Everbright valve is pressure vessels, boilers, pressure piping systems, such as the use of widely used as a pressure safety device safety valve to ensure the safe operation of the pressure system. When the tank pressure exceeds the design requirements, the safety valve automatically opens, exhaust gas to reduce the high pressure inside, to prevent damage to the vessel or pipeline. And when the pressure within the container to normal operating pressure, i.e. off automatically to avoid all of the gas discharge vessel overpressure, resulting in waste and production interruptions. When the pressure is double spring safety valve device exceeds a specified operating pressure and meet safety valve opening pressure, the internal role of the media in trouble flap above loading mechanism force is greater than the force exerted on it, and then leave the valve seat safety valve open, the media inside the device is discharged through the seat, if the safety valve displacement is greater than the equipment Shandong safety discharge valve, the pressure inside the device that is gradually decreased Double spring safety valve, and through a short exhaust After that the pressure drop back to normal operating pressure. Pressure within this time to turn the valve on top of the force is less than the force applied to the loading mechanism on top of it, they pressed the valve seat and the media to stop the discharge, equipment to maintain normal operating pressure continues to run. Therefore, the safety valve is a force on the valve through the medium of growth and decline of the force and the loading mechanism, or turn itself off in order to achieve the purpose of preventing overpressure device. Valve play a security role in the system. When the system pressure exceeds a predetermined value, the safety valve opens, the system part of the gas into the atmosphere, so that the system pressure does not exceed the allowable value, in order to ensure that the system pressure is too high and not because of the accident. Also known as a safety valve relief. Valve is an automatic valve automatically open when the amount of fluid discharged rated medium overpressure, when the pressure is back to normal and automatically shut down to prevent the media flow. It is important to protect the equipment and process systems on the pressure vessel, and in the aerospace, petrochemical, energy, metallurgy and other industries have a wide range of devices and equipment used.
