There are significant differences between the terminal water testing device and the water testing valve in many aspects. They each serve different systems and functions:
First of all, functionally, the terminal water testing device is The core component of the automatic sprinkler system, designed to check the reliability of the system and ensure timely response in the event of a fire by testing the water filling speed of dry and pre-action system pipes. The water test valve is used in the medical field for signal detection and parameter adjustment of MRI equipment.
Secondly, in terms of component composition, the terminal water testing device is usually set up in an easy-to-operate position and equipped with efficient drainage facilities, and its flow coefficient matches the system nozzle. The water test valve includes a wider range of components such as sprinklers, alarm valve groups, etc., and its water outlet method is connected to the drainage pipe.
In terms of application principle, the terminal water test device relies on a variety of engine technologies, such as models from Pratt & Whitney, General Electric and Rolls-Royce, while the water test valve uses General Electric’s GenX Engine, its performance is more advanced and more energy efficient. The power sources and working principles of the engines are also different. The former is propelled by jet reaction force, while the latter belongs to the turbofan engine category.
Finally, in terms of installation position, the terminal water testing device is placed at the most unfavorable point of the alarm valve water supply for real-time testing of the system, while the water testing valve may only be used for terminal water testing when specific needs arise. The device is connected and used less frequently.
In summary, there are obvious differences between the terminal water testing device and the water testing valve in terms of original design intention, component configuration, technical principles and practical application scenarios. Both serve fire extinguishing systems and medical imaging equipment respectively. maintenance and testing needs.
