Introduction
The new safety valve calibration table developed and manufactured by our company is suitable for performance testing of setting pressure, return pressure and sealing of direct load type and pilot type safety valve.Related standards:TSGZF001-2006 safety valve safety technical inspection regulations, GB-T12242-2005 pressure release device performance test specification, GB-T12241-2005 safety valve general requirements, GB-T12243-2005 spring direct load safety valve, in line with safety valve performance test National standard.
Features and features:
1. Pneumatic clamping and air-driven hydraulic clamping device are used, the clamping force is adjustable, and a pressure gauge is displayed to show the corresponding clamping force. A comparison table of pressure and clamping force is provided to facilitate the operator to verify the pressure and communication according to the safety valve. Select the proper clamping force.
2.Gas test: Water is used as the test pressure source, the pressure is boosted by a gas-driven liquid booster pump, and the pressure of the medium after boosting is 0-32MPa.
3.All valves, fittings and joints are made of stainless steel.
4. The test process is computer-operated, automatically records the data, and can print the relevant data and pressure-time graph of the test process.
5. Two sets of test and check bases, including two clamp bases, for DN10-DN200 test use.
6. Equipped with multiple test fixtures to meet test requirements using safety valves
