Reference Standards:
TSGZF001-2006, GB-T12242-2005, GB-T12241-2005, GB-T12243-2005
Range of application: applicable for the set-pressure, setback pressure and sealing tests of direst loaded and pilot-operated safety valves.
Technical Parameters:
â¢Maximum drift diameter: DN400mm
â¢Maximum test pressure: 60Mpa
â¢Pressure test precision: pressure gauge of 0.4 grades (Users can choose a more precise one.)
â¢Test medium: nitrogen, compressed air or clean water (Gas liquid dual-capable one can be designed.)
Functions and Characteristics:
â¢The equipment has advanced design principle. It uses pneumo-hydraulic booster pump as its clamping pressure source and air driven gas booster pump as its test pressure source. A gas cylinder is equipped, which enables the test to be conducted continuously.
â¢The test pressure is adjustable and the process of pressurization is stable.
â¢Clamping pressure source and test pressure source can use imported booster pumps from America or Germany, which have a wide range of output pressure.
â¢All the manual high pressure valves, pipe fittings and connectors are imported ones, which guarantee their pressure levels, safety and reliability. Most gas and liquid media are available.
MAQ-400 /48BA Functions and Characteristics:
â¢Maximum drift diameter: DN400mm
â¢Maximum test pressure: 48Mpa
â¢Pneumatic control hydraulic clamping device is adopted. Clamping force is adjustable. The equipped pressure gauge displays the corresponding clamping force and provides a comparison table between the pressure and the clamping force, which facilitates operators to choose appropriate lamping force according to the safety valve calibration pressure and the drift diameter.
â¢All the valves, pipe fittings and connectors are made of stainless steel.
â¢The test is operated manually and operators record the data.
â¢The system includes two test and calibration tables. One is equipped with two clamping devices. There are totally three clamping devices: one is for safety valves of DN15-DN100; one is for safety valves of DN100-DN200; one is for safety valves of DN200-DN400.
â¢Various test tools are equipped to meet the needs of customers on different kinds of safety valves.
