Pressure relief valve

Product Description

Work principle

Pressure relief valve is composed of needle valve, pressure gauge, main valve, pilot valve and connecting pipe, which is a kind of hydraulic control valve. The main valve is divided into two parts by the diaphragm, the lower cavity of the diaphragm is the water flow channel, and the upper cavity is the control room, which controls the opening and closing of the main valve disc. The pilot valve itself is a pressure relief valve, it also has a control room and water flow channels, and the opening and closing of the valve disc is controlled by the control room. The needle valve is the throttle valve, which controls the flow of water in the connecting pipe

function

When the upper limit of the safe pressure is reached, it can be automatically turned on to reduce the pressure to ensure safety. The most common is the pressure relief valve on the pressure cooker at home, which is a simple mechanical pressure relief, and the pressure relief valve of the heating and air conditioning system, which is a water floating pressure relief valve. It is a kind of valve that releases part of the pressure when the system pressure exceeds the design specification to make the system work normally.

Feature

1. Accurate and maintain the safe and stable pressure, once the pressure is over, the pressure relief valve can be fully opened and timely pressure relief.
2. The closing speed is adjustable to eliminate pressure fluctuations.
3. The diaphragm transmission mechanism reduces the operating hysteresis to a minimum.
4. It can be installed in any position, and can be repaired and inspected without changing the pressure setting value or removing it from the pipeline.
