1988165438+1October1kloc-0/is a day that Mr. Ming Cidong will never forget. On this day, after overcoming the unimaginable difficulties of ordinary people, under great pressure, Hualin Special Control Valve Research Institute, the predecessor of Hualin Company, was born.
At that time, our regulator industry mostly used imported valves, which were expensive. In this case, Mr. Ming Cidong loudly put forward the slogan of "localization of control valves". He led the technicians of Hualin Special Regulating Valve Research Institute to go deep into the specific application site of customers and deal with various faults, from which he accumulated a lot of first-hand information, and then went back to the institute to do experiments and improve it bit by bit. At the beginning of his business, he almost traveled all over the country; In the experiment of product development, he often has no rest days for several months in a row, and the hardships are beyond ordinary people's imagination.
Regulating valve products can be simply divided into two categories: one is ordinary valve and the other is special valve. Most valves (60%∽70%) belong to ordinary valves, which are used under moderate conditions such as low temperature, low pressure and ordinary medium. Special valves refer to valves that are used in special environments such as high temperature, high pressure, strong acid and strong alkali and need special design to meet the requirements. Obviously, the technical requirements of special valves are higher, more difficult and more demanding from customers.
It is a fundamental starting point for Mr. Ming Cidong to start his business to "meet the urgent needs of customers and solve the problem of industrial self-control". Difficult and special valves are the soft underbelly of the regulator industry, so Mr. Ming Cidong decided to chew this hard bone first. Under his leadership, Hualin has successively completed a number of national, provincial and ministerial-level scientific research projects, introduced hundreds of domestic projects, and successfully developed hundreds of special control valves, which solved many problems such as high temperature and high pressure, strong corrosion, anti-clogging, anti-corrosion, emergency action, suspension crystallization, micro-pressure automatic control and so on. 1April, 1992, four products, such as anti-cavitation high pressure differential control valve, perfluorinated corrosion-resistant single-seat control valve, corrosion-resistant cut-off butterfly valve and corrosion-resistant ball valve special for water treatment, obtained national patents. 1996 in may, Sichuan baxian hualin special regulating valve research institute was transformed into Chongqing hualin mechanical engineering co., ltd.
In the long-term customer tracking service, Mr. Ming Cidong further found that the control valve, as a long-standing problem in the field of automatic control, is manifested in the following aspects: 1, too heavy. The weight of control valve is dozens, hundreds or even thousands of kilograms, which brings great trouble to transportation, hoisting, installation and maintenance. 2. There are many kinds. Control valves can be divided into nine categories in structure, from which hundreds of series and tens of thousands of specifications are derived, which brings great problems to calculation, selection, maintenance and spare parts. 3. Poor reliability. Performance: running, leaking, dripping, blocking, jamming, dynamic difference, short life and many other aspects.
These so-called old, big and difficult problems are also common in ordinary valves which account for 60%-70% of all regulating valves. In order to solve the above problems, a new product is urgently needed, which has the following characteristics: 1, and the weight must be greatly reduced; 2. Must have all the functions of single-seat valve, double-seat valve and sleeve valve, and can adapt to the occasions of ball valve, eccentric valve and butterfly valve, and then replace many products with a full-function product to solve the long-standing problems of various control valve products; 3. Reliability must be improved.
In order to accomplish this idea, Mr. Ming Cidong deeply studied the development history of control valves, and found that the reasons for the less and less application of pneumatic ZMA□ and electric ZZZ □ are the backward application level (old products in the 1960s), large volume, complicated flow path, small Kv, easy blockage and poor reliability. However, the weight, volume and height of the fine valve and Cv3000 products have all decreased by 30%, and the Kv value has increased by 30%, which is an improvement compared with the original old products, so it became the mainstream at the end of the 20th century, but this dominant position will soon be replaced by the angular stroke valve.
This is because, compared with the angular stroke valve (the spool moves up and down), the straight stroke valve has the following nine disadvantages:
1. From the flow path analysis, the flow path of the straight-stroke valve is complicated, resulting in four shortcomings:
(1)Kv value is small;
(2) poor anti-clogging;
(3) large volume and heavy weight;
(4) poor appearance;
2. The straight stroke valve stem moves up and down, resulting in large sliding friction, which leads to two disadvantages:
(5) The valve stem has poor sealing and short service life;
(6) poor vibration resistance;
3. From the structural analysis, there are three shortcomings:
(7) The allowable pressure difference of a single seal is small;
(8) The double seal leaks seriously;
(9) The valve core is in the middle, which can't avoid the direct erosion of high-speed media (cavitation and particles) and has a short service life.
Therefore, the wide application of angular travel valve will become inevitable. Of course, this does not mean that the angular stroke valve has no shortcomings. Mr. Ming Cidong envisioned that the new product should overcome the shortcomings of both the straight stroke valve and the angular stroke valve, and have the advantages of both.
In order to achieve this goal, Mr. Ming Cidong led all the staff of Hualin. After several years of efforts and hundreds of times of continuous improvement and perfection, he finally got a product with wide adaptability, excellent performance and greatly reduced weight. This is the full-function ultra-light control valve that later caused revolutionary changes in the control valve industry. Compared with the common control valve, the full-function ultra-light control valve has achieved a qualitative leap in the following aspects:
1, weight decreased by 70∽80%. Cv3000 series and domestic small regulating valves reduce the weight of old products by 30%. The weight of the full-function ultra-light control valve is reduced by 70%-80%, which truly realizes the instrumentation and lightweight of the control valve.
2. The types of regulating valves are greatly reduced, and the calculation, selection, installation, maintenance and spare parts work are simplified. The traditional nine kinds of control valve products have single function, many shortcomings and great limitations. Full-function ultra-light control valve is fully functional:
(1) Small leakage (one in a million ∽ one in a million)
(2) The allowable pressure difference is large (up to PN level)
(3) Good anti-blocking performance (the medium is straight through, and it is easy to take away the unclean medium)
(4) The adjustable ratio is large (R= 100∽200)
(5) Good working performance at small opening.
(6) The discharge coefficient kv is large.
(7) Best cost performance, high reliability, light weight and beautiful appearance.
Therefore, except for a few angle valves, three-way valves and some special occasions, they can all be replaced by one product, which greatly simplifies the variety of regulating valves.
3. Extremely high reliability. From the perspective of system engineering, Mr. Ming Cidong comprehensively analyzed the problems and unreliable factors existing in the past use of control valves, and put forward corresponding countermeasures and solutions, such as improving the reliability of sealing surface, guiding without gap and limiting movement, and adopting forged valve body for high temperature and high pressure valves, which greatly improved the reliability of control valves.
The development of full-function valves is a sign that the national industry has changed from simple imitation in the past to independent innovation in the field of regulating valves. So once it came out, it won wide social attention:
1997-5 full-function ultra-light control valve prototype was born;

Today, Hualin has become a well-known brand in the domestic control valve industry, and Hualin Group has become a medium-sized scientific and technological enterprise group integrating research and development and production of control valves, with two production bases in Chongqing and Deyang (covering an area of 150 mu). The company is a key supporting enterprise of the National Innovation Fund and an ISO9000 certified enterprise. Over the years, it has been rated as "an enterprise that values contracts and keeps promises" and won many national, provincial and municipal scientific research achievement awards.
In the process of hard work, Mr. Ming Cidong put forward a series of goals for himself and encouraged himself to continue to struggle. Sixteen years later, Mr. Ming Cidong is gradually realizing his goal:
First, "experts". From the initial professional and technical personnel to the first-class experts in the industry, he has published 3 technical monographs with more than 200,000 words, solved and overcome more than 0/00 scientific and technological difficulties, and won 5 national awards for his products. ...
Second, "inventor". Mr. Ming Cidong has set the goal of applying for 100 patents by 20 15 years. Up to now, he has 15 patents, of which the full-function ultra-light control valve was valued at 310.4 million yuan in 2002, and has now become the company's fist product.
Third, "entrepreneurs". As a successful entrepreneur, he should be worth hundreds of millions and make innovations in management science and art. From June 5 to April 38, 2004, he was selected as one of the "Top 100 Outstanding Management Innovations in Asia" in the "First Asian Management Innovations" jointly organized by SASAC, the National Development and Reform Commission and the Asian Young Chinese Enterprise Management Innovation Research Association.
Fourth, "entrepreneurial thinker". A successful entrepreneur must have a complete set of corporate philosophy, corporate culture and business philosophy with his own corporate characteristics to support and guide the enterprise, so that the enterprise can maintain long-term, stable and healthy development in the fierce competition. It is easy to prosper for a while, but difficult to build a century-old shop. At present, he is writing the book Enterprise Thinking. Among them, the excerpted paper "Solutions for Three Monks Without Water to Drink" was published at the China Management Science Innovation Conference and won the first prize.
Fifth, assuming that the above goals are achieved, what is the ultimate destination of successful enterprises? This is the most critical and important thing: is it profligacy? Or continue to improve and do something more meaningful? Mr. Ming Cidong believes that it is time to repay the society, the party's reform and opening-up policy and do a public welfare undertaking.
Sixth, "scholars." The process of life is the process of learning, and so is running a business, which is called a learning enterprise. As the boss of an enterprise, you should be a "coach". Therefore, Mr. Ming Cidong's sixth goal is to be a scholar, sum up his own experience and lessons to train employees, train college students (as visiting professors) and train customers, which can also be used for reference by others. At present, I am writing four books: Graphic Philosophy, Top Ten Mentality of Winners, Life Perception and Life Health Care.
"Don't work for the same purpose, but have ambition in the world", which can be said to be the best description of Mr. Ming Cidong. Hualin Hualin means "the Chinese nation stands tall in the world". This is also the pursuit of Mr. Ming Zhidong's lifelong efforts. Under his leadership, while creating tangible value for the society, Hualin spared no expense in investing a lot of manpower and material resources to spread the knowledge and technology of control valves by holding lectures, studying classes, publishing books and establishing the most professional website of the domestic control valve industry-China Control Valve Network. At the same time, constantly sum up management practices, improve management concepts, and explore management methods suitable for China's national conditions.
"If you are not indifferent, you will have no ambition. If you are not quiet, you will be far away." Mr. Ming Cidong is simple and does not like publicity. Adhere to the concept of "people first, honesty first"; Hobbies: reading, writing, poetry, photography, painting and calligraphy collection, traveling; Combination of arts and sciences, combination of Chinese and western. Mr. Ming Cidong used his own life to practice the ideal of serving the country in the technician industry!
