Brief introduction of gas lift pressure reducing valve
Air pressure reducing valve uses the opening of the opening and closing parts in the control valve body to adjust the flow rate of the medium and reduce the pressure of the medium. At the same time, the opening of the opening and closing parts is adjusted by the pressure behind the valve to keep the pressure behind the valve within a certain range, and cooling water is injected into the valve body or behind the valve to reduce the temperature of the medium. This kind of valve is called decompression and desuperheating valve. The characteristic of this valve is to keep the outlet pressure and temperature within a certain range when the inlet pressure is constantly changing. Pressure reducing valves can be divided into diaphragm type, spring diaphragm type, piston type, lever type and bellows type according to their structural forms; According to the number of valve seats, it can be manual single-seat and double-seat type; According to the position of intervertebral disc, it can be divided into active type and reactive type.
Air pressure reducing valve's working principle
1 and QPF-F50 pneumatic balance valves, also known as main pressure reducing valves, are used to adjust the pressure value of compressed air in the pneumatic circuit to make the set pressure value close to constant.
2. The valve is a pressure regulating-overflow combined valve. When the outlet pressure is lower than the set pressure, it acts as a pressure regulating valve to raise the pressure to the set pressure. When the outlet pressure is higher than the set pressure, it acts as an overflow valve to reduce the outlet pressure to the set pressure. So as to ensure that the outlet pressure is always stable at the required set pressure.
3. Because the valve has the characteristics of pressure regulating valve and overflow valve at the same time, it can replace the pressure regulating valve and overflow valve at the same time, which is simpler and more compact than setting the pressure regulating valve and overflow valve separately in the gas path system. At the same time, the set pressure difference between the pressure regulating valve and the overflow valve is eliminated, which ensures that the air pressure in the system can be adjusted and stabilized at the required set pressure value more accurately.

Air pressure reducing valve is very small, so we hardly pay attention to it in our daily life, but it silently plays an unimaginable role in our life, protecting our lives. If the pneumatic valve doesn't work, the pipeline may burst and so on. At that time, the threat to our life safety will be great, so everyone should understand its working principle, pay more attention to it and see if it can work normally. If there is a problem in air pressure reducing valve, it should be solved in time.
