Product Parameters

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: Use nitrogen in a nitrogen cylinder as the test pressure source, pressurized by a pneumatic booster pump, and used for testing. Equipped with a gas booster pump, the driving air source is 2-8bar.

3.Liquid test: Use water as the test medium, pressurized by the pneumatic liquid booster pump, and used for the test test. Equipped with an air-driven liquid booster pump,the booster medium is water, the driving air source is 2-8bar,.

4.All valves, fittings and joints are made of stainless steel.

5.In addition to the manual control of the check valve, the test process is computer operation, automatic clamping, automatic data recording, and printing of relevant data and pressure-time curve diagrams of the test process.

6. One sets of test and check bases, for DN10-DN300 test use.

7. The computer adopts industrial computer, which has stable performance, shock resistance and firmness. During the verification operation, the appearance inspection status, the reason for the failure, and the maintenance status of the inspected safety valve can be selected, and it can be automatically imported into the inspection report of the verification task and automatically saved.

8. During the calibration process, the setting pressure can be automatically measured and recorded, and the three qualified setting pressure values and average values measured can be automatically imported into the verification report of the inspection task, with a pressure-time curve attached.

10. Equipped with multiple test fixtures to meet the test requirements of the safety valve of the checkered series.

Application Fields:
Used for testing all kinds of safety valve, such as spring directly load safety valve, Power assisted safety valve, Supplementary loaded safety valve, fully open, slightly open, flange, thread type safety valve. Safety valve test bench is to use high pressure air or nitrogen as the medium to test the sealing performance of the safety valve, jump pressure, back seat pressure, etc., for a variety of safety valve set pressure adjustment, set pressure test, discharge pressure test, back seat pressure test, test the pressure sealing performance of the safety valve, leakage rate. Safety Relief Valve Test bench has obvious advantages in techniques, test accuracy, safety etc.

The safety valve checkout platform is a device that simulates the working environment of the safety valve offline and makes the internal pressure rise to the safety valve lift.

At the same time, the pressure gauge on the device can show the starting pressure of the safety valve.

The test pressure can be checked to check the starting pressure (also called opening pressure, setting pressure) of the safety valve.  Suitable for performance testing of fixed pressure, backseat pressure and tightness of direct loading and pilot safety valves.
