When the pressure is double spring safety valve device exceeds a specified operating pressure and reach the safety valve opening pressure relief valve Weifang A38Y-16C, the role of the media in trouble inside flap above loading mechanism force is greater than the force exerted on it, and So leave the valve seat, the valve is turned on, the media inside the device is discharged through the seat, if the safety valve displacement is greater than the safety discharge device, the pressure inside the device that is gradually decreased, but also through the exhaust after a short time, That 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 valve manufacturers, 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 seals: valve adjustment is completed, it should be sealed to prevent the casual good condition change has been adjusted. When renovations Weifang double valve spring safety valve, the valve before removing the screw and adjust the position of the adjustment ring should write down, in order to work on the adjustment trimmed. After the re-adjustment should be sealed again. Valve Co., Ltd. Shandong Everbright valve manufacturer specializing in the production, welcome new and old customers to order our products!
