The relief valve check ( testing machine) Safety valve calibration machine is a kind of offline simulation relief valve working environment, and make the internal pressure to the jump, at the same time can through the device of pressure gauge shows pressure relief valve of takeoff device. Can check jump pressure relief valve Also called opening pressure, setting pressure) Seal test pressure. Scope of application: applicable to direct load type and pilot operated relief valve setting pressure, back pressure and sealing performance testing, etc. Relevant standards: GB12242 - The relief valve performance test method of relief Industrial Valves check 98 main technical parameters: suitable size: DN 15 - DN200mm; A test of the valve number: 1. Pressure range: 0 ~ 40 mpa; Pressure precision: 0. 4 level gauge; Drive source: compressed air - 6 10条; Overall dimensions: 1300 mm * 800 mm * 1200 mm; Relief valve check Taiwan booth parameters: 1, the DN100 relief Industrial Valves installed booth Cu: relief valve DN25 set-up a DN100 high pressure: PN 32 mpa maximum loading card: 50 kn working medium: clean air, nitrogen working temperature: 0 - 50 ℃ under air displacement: 0. 3 to 0. 8 mpa2, DN200 relief valve installed booth Cu: relief valve DN100 set-up a DN200 highest pressure: PN 16 mpa maximum loading card: 100 kn working medium: clean air, nitrogen working temperature: 0 - 50 ℃ under air displacement: 0. 3 to 0. 8 mpa3, DN400 relief valve installed booth Cu: relief valve DN200 one DN400 highest calibration pressure: PN 8 mpa maximum loading card: 300 kn working medium: clean air, nitrogen working temperature: 0 - 50 ℃ under air displacement: 0. 3 to 0. 8 mpa relief valve check main functions and characteristics: advanced the design principle of the equipment using pneumatic liquid booster pump as clamping pressure source, and as a source of test pressure pneumatic gas booster pump, equipment is equipped with a cylinder, can test continuously; The test pressure can be adjusted, pressure rise rate can be set; Clamping pressure source and test pressure source adopt the imported booster pump, output pressure range is extensive; All high pressure valves, pipe fittings and adopt the import material 316 products, guarantee the withstand voltage level, safe and reliable, and can accommodate most of the gas and liquid medium. Power-fail protection function, power system automatically after unloading, the termination of the test, to ensure maximum operating personnel and equipment safety. Relief valve check table features 1, have according to the step of different diameter and pressure pneumatic clamping structure; 2, according to the calibration pressure size of switching mechanism; 3, according to user needs to match the computer display, print, store the data.
