Valve is special equipment (boilers, pressure vessels, pressure piping, etc.) a limit on the pressure relief plays an important role in the security annex. General safety valve mounted directly on the special equipment, his design, manufacture, installation, use, testing, and other special equipment must comply with the requirements of the relevant provisions of A40YC spring safety valve manufacturers, because it moves better reliability and performance bad is directly related to the equipment and personal safety valve type, and is closely related to energy conservation and environmental protection. Appropriate choice of valve should consider the following aspects: 1, structure, depending on the process conditions and the working media device characteristics. Generally boilers, pressure vessels discharge capacity is not the case multi-use spring-loaded safety valve, safety valve otherwise choose better. 2. If the media toxic, flammable, should choose a closed valve 3, each valve has its own working pressure range, the choice should be selected in accordance with the actual needs. 4, the choice of emissions vent valve must be greater volume of equipment, so as to ensure that part of the media were excluded to avoid the pressure continues to rise. Safety valve with radiator use A40Y-C type with radiator spring safety valve is suitable for operating temperatures ≤420 ℃, A40Y-C type with radiator spring safety valve is suitable for operating temperatures ≤450 ℃ equipment and piping for air, LPG and other media, as the overpressure protection device. When the equipment and piping within the pressure exceeds the allowable value safety valve, safety valve spring radiator will automatically open the valve, Shandong, then the whole emissions; when the pressure is reduced to a predetermined value, the radiator spring safety valve will automatically closed, protective equipment and safe operation.
