The ZJHP quick change pneumatic thin film single seat regulating valve adopts a top guide structure, with a compact valve body structure and an S-shaped fluid channel. The pressure drop loss is small, the flow flux is large, the adjustable range is wide, and the accuracy of flow characteristics is high. The guiding area of the valve core is large and has strong anti vibration performance. The valve seat closing performance meets the GB/T4213-92 standard. The regulating valve is equipped with a multi spring diaphragm actuator, which has a small structure and large output force. It is more suitable for high temperature, low temperature, and small pressure difference before and after the valve, which require high reliability and closing performance.

Q1:what is the safety valve ?
1. The main purpose of safety valves is to protect life, property and the environment. A safety valve is designed to open and release overpressure in a container or device, and to re-close and prevent further fluid release when it returns to its normal state.
2. A safety valve is a safety device that is in many cases the last line of defense. It is important to ensure that the safety valve can operate at all times and under all circumstances. Safety valves are not process valves or pressure regulators and should not be abused. It should be run for one purpose only: overvoltage protection.\
Q2:How does a Safety Valve work?
The working principle of a safety valve can be summarized as follows:
1. Open: When the system pressure exceeds the set pressure of the safety valve, the valve disc opens under the action of medium pressure and spring force, releasing pressure.
2.Keep open: When the system pressure stabilizes within the set pressure, the spring stabilizes, the system remains under stress, and the safety valve remains open.
3. Close: When the system pressure is lower than the set pressure of the safety valve, the spring cannot lock and seal, and the valve disc closes under the action of medium pressure, and the medium pressure no longer increases.
