A bellows valve is a valve that uses bellows as the sealing element of the valve stem. The advantage of using bellows as the valve stem on the valve is that it can eliminate the shortcomings of ordinary valve stem packing seals that age quickly and are prone to leakage. At the same time, it improves energy efficiency and enhances the safety of production equipment. Bellows valves are also widely used in production and life, such as farmland water conservancy, petrochemical industry, aviation and other fields. Therefore, the understanding of bellows valves cannot be ignored. Next, I will introduce to you the working principle and manufacturer of bellows valves.
1. The working principle and use advantages of bellows valves
1. Working principle
The bellows seal stop valve adopts the bellows seal design, completely eliminating the need for It overcomes the shortcomings of ordinary valve stem packing seals that age quickly and leak easily. It not only improves energy efficiency, increases the safety of production equipment, reduces repair costs and frequent maintenance, but also provides a clean and safe working environment. Bellows valves, firstly because of their simple structure and secondly because of their low price, have almost no "competitors" so far. The only thing that can compete with the diaphragm valve is the invention of the so-called bellows, commonly known as the bellows valve.
Products are widely used in various fields such as municipal construction, farmland water conservancy, thermal power generation, petrochemical industry, metallurgical mining, fire protection and environmental protection, food, shipping, medicine and light textiles. Due to its high price, this kind of bellows valve has better technical advantages than diaphragm valves, but it is still difficult to compete with diaphragm valves, as introduced in this article. ?This type of valve should generally be installed horizontally in pipelines.
2. Advantages of use:
Double sealing design (bellows packing) If the bellows fails, the valve stem packing will also avoid external leakage and comply with international sealing standards;
p>
No fluid loss, reducing energy loss and improving factory equipment safety;
Long service life, reducing the number of maintenance times and reducing operating costs;
Strong and durable bellows seal Designed to ensure zero leakage from the valve stem and provide maintenance-free conditions.
2. Manufacturer
1. Shanghai Keke Valve Group Co., Ltd.
Shanghai Keke Valve has R&D, manufacturing, testing, and testing capabilities, and its product structure Reasonable, unique and exquisite production technology, complete specifications, reliable quality. Shanghai Keke Valve mainly adopts American API, ANSI, British BS, German DIN, French NF, Japanese JIS, JPI, Chinese GB and other standards to produce butterfly valves, gate valves, ball valves, globe valves, check valves, plunger valves, and cocks. valves, regulating valves, traps, pressure reducing valves, power station valves, filters, etc. We can also manufacture various special valves according to user requirements.
2. Shandong Tengyuan Plastic Industry Co., Ltd.
is a company specializing in the production of PE water supply pipes, PE gas pipes, PE flame retardant and antistatic mining pipes, and PE ground source heat pump pipes , PE siphon drainage pipes, PERT floor heating pipes and supporting PE water supply pipe fittings, PE gas pipe fittings, PE flame retardant, anti-static mine double-resistance pipe fittings, PE ground source heat pump pipe fittings, PE spray-coated anti-corrosion steel flange pieces, PE ball valves, PERT A high-tech enterprise specializing in floor heating pipe fittings, PE siphon drainage pipe fittings and other series of products.
The above is an introduction to the working principle and use advantages of bellows valves and the knowledge of some manufacturers. I hope that friends in need can be helpful in this regard. The double sealing design of the bellows valve makes it less likely to leak, eliminates fluid loss, reduces energy consumption, and improves equipment safety. Improves the service life of the equipment. Therefore, bellows valves are widely used in all aspects of our production and life. I hope the above content introduction can help everyone.
