Product Description
Relief valve, also known as return valve, is a hydraulic pressure control valve. Relief valves are divided into two categories: spring type and rod type. In addition, there are impulse type safety valve, pilot type safety valve, safety switch valve, safety decompression valve, deadweight safety valve and so on. The relief valve is the overflow through the valve port to adjust the working pressure of the system or limit its maximum working pressure to prevent the system from overloading. In the assembly or use of the relief valve, due to the damage of the O-ring seal, the combination seal ring, or the loosening of the installation screw and pipe joint, it may cause undue external leakage.
Safety relief valve has spring type and rod type two categories. In addition, there are impulse type safety valve, pilot type safety valve, safety switch valve, safety decompression valve, deadweight safety valve and so on. Spring type safety valve mainly relies on the force of the spring and work, spring type safety valve and closed and not closed, generally flammable, explosive or toxic media should be selected closed, steam or inert gas can be selected not closed, in the spring type safety valve with a wrench and without a wrench. The function of the wrench is mainly to check the flexibility of the valve disc, and sometimes it can be used as a manual emergency pressure relief. The lever safety valve mainly relies on the force of the lever weight to work, but the large volume of the lever safety valve often limits the selection range. Use a safety valve with radiator when the temperature is high.
Constant pressure overflow effect: In the quantitative pump throttling regulation system, the quantitative pump provides a constant flow rate. When the system pressure increases, the flow demand will decrease. At this time, the relief valve is opened, so that the excess flow flows back to the tank, to ensure that the relief valve inlet pressure, that is, the pump outlet pressure is constant (the valve port is often opened with pressure fluctuations). Pressure stabilizing effect: The relief valve is connected in series on the return oil circuit, the relief valve produces back pressure, and the stability of the moving parts is increased.
