Spring-loaded safety valve with radiator is mainly suitable for high temperature and pressure environment, the main models are A48Y, A48SH, A48SB, A40Y and so on. Flange safety valves like A41, A42, etc. can also be equipped with a radiator under special requirements. With spring-type safety valve with a radiator for operating temperature "C" ≤ 425 ℃; "I" ≤ 500 ℃; "V" ≤ 500 ℃ steam and other media equipment or piping, as overpressure protection device. Connecting flange standard press JB / T ...... 94 series 1, series 2. Spring-loaded safety valve with radiator commonly used in power station boiler operation, is an effective protection of power plant boilers, is the most important and last safety relief device. In recent years, the state attaches more importance to the safety of boilers and pressure vessels, as well as the implementation of energy-saving emission reduction, high-temperature high-pressure safety valve safety, sealing, back seat sensitivity, energy-saving and put forward higher requirements. As we all know, the working status of the safety valve depends mainly on the sensitivity of the spring. Spring is one of the key parts of the safety valve, the quality of which directly affects the safety valve performance is good and bad, so the safety valve spring with the general equipment used in the spring compared with some special high requirements. The setting pressure of the safety valve is obtained by adjusting the amount of compression of the spring. When the size of the safety valve has been determined, the stiffness of the spring determines whether the discharge pressure, the relief pressure, the opening height and the mechanical property of the safety valve can be satisfied Relevant standards. Safety valve action performance is stable (especially at high temperatures), spring design matching and manufacturing quality plays an extremely important role. Shanghai Wuyue safety valve manufacturers will be used within each nominal pressure range of the spring is divided into a number of pressure levels (that is, with a number of springs), it is clear that the more points, the more the number of springs, the actual use of each spring The more accurate the stiffness, the easier it is to operate the safety valve. However, the spring material is generally based on the medium and temperature to determine. Safety valve material, the domestic manufacturers usually use 50CrVA, for corrosive media, are generally used 50CrVA surface spray Teflon, but only for temperatures less than or equal to 200 ° C operating conditions, higher than 200 ° C Another corrosion or low temperature conditions, the general use of 304,316 stainless steel or Inco nickel material. For high temperature and high pressure safety valve (such as steam station superheated steam drum), such as the use of 50CrVA material, you need to add insulation to isolate the spring chamber, or the bonnet is designed to open, can also use 30W4Cr2VA, W1804V and other high temperature Spring steel. This shows that the spring-loaded safety valve with a radiator is mainly suitable for high temperature and pressure work environment, the purpose is to speed up the internal heat relief valve to prevent excessive spring deformation of the spring temperature, affecting the normal spring sensitivity. Commonly used safety valve for the operating temperature, such as carbon steel WCB (C) ≤ 350 ℃; chromium-molybdenum steel 1Cr5Mo (I) ≤ 500 ℃; chromium molybdenum vanadium steel 15CrMoIV (V) ≤ 540 ℃, the temperature exceeds 350 ℃, safety Valve basically need to be equipped with a radiator. Spring-loaded safety valve with radiator is used for overheating saturated steam at high temperature and high pressure. It is suitable for power boiler, cracking furnace, once-through boiler, reheater, power station boiler, waste heat recovery boiler equipment and power, steel, metallurgy and other industries.
