Weifang double valve spring safety valve _ _ Valve Model 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. Valve play a security role in the system. When the system pressure exceeds the predetermined value, the valve opens Weifang double spring safety valve, the system is part of the gas into the atmosphere, so that the system pressure does not exceed the allowable value, in order to ensure the system does not cause excessive pressure accident occurred. Also known as a safety valve relief. Valve is an automatic valve safety 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 Shandong valves on pressure vessels and process system, and in the aerospace, petrochemical, energy, metallurgy and other industries have a wide range of devices and equipment used. The adjustment ring is used to change the flow of the medium in the valve flap folding rear side reflection angle, thereby changing the size of the fluid forces, in order to adjust the pressure back seat. Increased adjustment ring on the safety valve when Weifang A38Y-16C, turning angle decreases, the fluid force decreases, so that the back seat pressure increased. Conversely, when the adjustment ring on the lower back seat pressure is reduced. Of course, while the adjustment ring in the back seat pressure change also affects the discharge pressure, which increases the adjusting ring so that the discharge pressure has increased, reducing pressure on the adjusting ring so that emissions decreased, but the degree of impact is not back Pressure on as obvious.
