The copper safety valve is a valve that automatically controls and protects. Instead of relying on any external force, he uses the force of the medium itself to discharge a certain amount of medium to prevent the pressure inside the system from exceeding a predetermined safety value. When the pressure returns to normal, the safety valve automatically closes to prevent the media from continuing to be removed. It is suitable for pressure control and protection of pressure systems such as boilers, hydraulic presses, hydraulic presses, air compressors, and air conditioners.

This product is a valve that automatically controls and protects. Instead of relying on any external force, he uses the force of the medium itself to discharge a certain amount of medium to prevent the pressure inside the system from exceeding a predetermined safe value. When the pressure returns to normal, the safety valve automatically closes to prevent the media from continuing to be removed. It is suitable for pressure control and protection of pressure systems such as boilers, hydraulic presses, hydraulic presses, air compressors, and air conditioners. Safety valves are safety devices designed to prevent pressure equipment and containers from rupturing due to pressure build-up or pressure inside the container. The safety valve is a safety device widely used in pressure systems such as pressure vessels, boilers and pressure pipes to ensure the safe operation of the pressure system. When the pressure of the container exceeds the design specification, the safety valve is automatically opened to discharge the high pressure inside the gas reducer to prevent damage to the container or the pipeline. When the pressure in the container drops to the normal operating pressure, it is automatically closed to avoid exhausting all the gas due to overpressure of the container, resulting in waste and production interruption. The safety valve is mainly composed of a valve seat, a valve disc (spool) and a loading mechanism. The valve seat is integral with the valve body, and some are assembled with the valve body, which is in communication with the device. The valve flap is often attached with a valve stem that snaps onto the valve seat. Above the valve disc is the loading mechanism, the size of the load can be adjusted. When the pressure in the device is within a certain working pressure range, the force acting on the valve disc by the internal medium is less than the force exerted on the valve by the loading mechanism, and the difference between the two forms a sealing force between the valve flap and the valve seat. The valve flap is pressed against the seat and the media of the device cannot be discharged. When the pressure in the device exceeds the specified working pressure and reaches the opening pressure of the safety valve, the force exerted by the internal medium on the valve is greater than the force exerted by the loading mechanism on the valve, so that the valve flap leaves the valve seat and the safety valve opens. The medium inside is discharged through the valve seat. If the displacement of the safety valve is greater than the safety relief of the equipment, the pressure inside the equipment gradually decreases, and after a short period of exhaust, the pressure drops back to the normal working pressure. At this time, the internal pressure acts on the valve flap and the force exerted on the valve is smaller than the force applied by the loading mechanism. The valve flap is pressed against the valve seat, the medium stops discharging, and the device maintains normal working pressure and continues to operate. Therefore, the safety valve is closed or opened by the force of the medium on the valve flap and the force of the loading mechanism to prevent the device from overpressure.

Copper safety valve installation precautions
1. All safety valves should be installed vertically.
2. There should be no resistance at the exit of the safety valve to avoid pressure.
3. The safety valve should be specially tested before installation and checked for its official seal.
4. Regular inspection of the safety valve in use
