Valve manufacturers, valve, valve type Everbright Everbright Limited provided by Shandong valve. Valve Co., Ltd. Shandong China Everbright (www.sdgdfm.com) is specialized in the "valve" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Manager Ma. Double spring safety valve for the equipment and pipeline operating temperature ≤350 ℃ steam, air and other media. When the pressure inside the equipment and piping exceeds the allowable value, the valve automatically opens, and then the whole amount of emissions, when the pressure is reduced to a predetermined value, the valve automatically closes to ensure the safe operation of the equipment and piping. Explained that the valve is in a Y-connector installed two of the same type of safety valve specifications, its nominal diameter refers to the Y-connector inlet diameter, the combination is as follows: The main component materials Description: A38Y, A43H, A37H Safety In addition to the three-way valve for WCB outside material safety valve, the rest of the parts and materials are A47H, A48Y same type spring-loaded safety valve. 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 displacement is greater than the safety relief valve to vent device volume Weifang double spring safety valve, the pressure inside the device that is gradually decreased, but also through a short exhaust after pressure that drops 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, Shandong media to stop discharge valves, 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.
