ODMT Computer control Safety valve test bench is a new type device designed and manufactured by our company, The structural design are compact, Combined the air driven liquid booster pumps,gas/nitrogen booster pump,Precision high pressure gauge,Digital display clamping protector ,needle valves ,control switches ,electromagnetic valve ,Pressure relief regulating valve ,Pneumatic control ball valve ,pressure transducer ,data acquisition system ,Hydraulic clamping device ,data printer and other precision accessories are assembled in the frame or closed cabinet.
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.

1. Automatic hydraulic clamping, Adjustable clamping force, equipped with gauges displaying corresponding clamping forces, The material of the clamping valve fittings is stainless steel.

2.The same valve size, ODMT products can test bigger pressure; The same pressure, ODMT products can test bigger valve size; Provide quicker and more accurate clamping force. Control panel with different gauges for reference .

3. With Our self Products air driven booster pump , build up pressure quickly and Holding pressure constant; With high pressure stainless needle valve, installed in either direction, high pressure resistant, high durability; 

4.Normally we use double stage air driven high pressure gas booster pump and High pressure air driven liquid pump for building into the safety valve test bench. We are able to provide our customers better technical support, price and service.

5. Test various relief valves such as full-open, micro-open, metric, flanged and threaded etc. Safety valve test bench is used for various safety valve setting pressure adjustment, the whole set pressure detection, discharge pressure detection, back seat pressure testing, assessment of its pressure safety performance etc.. , Safety Relief Valve Test bench has obvious advantages in techniques, test accuracy, safety etc.
 

Structure and reliable, long life, high stability, no electricity, simple maintenance.

Safety Operation:use gas driven, no arc and sparks, it can be used in hazardous locations.

• Flexible application:different series of pumps can be used to obtain different pressure intervals and flow intervals. 

• Simple maintenance:Compared with other air-driving pumps,the pneumatic booster pump can perform the same job as other gas drive pumps, but with fewer parts and seals, and easier maintenance.

• Structure and reliable, long life, high stability, no electricity, simple maintenance.

• Automatic pressure holding, whatever the cause of the pressure drop, the pump will automatically start, keep the loop pressure constant.

Pneumatic pressurization technology is used to stabilize the pressure without fluctuation, and the output pressure can be adjusted. Automatic clamping system for quick valve installation and positioning.

Clamping pressure source pneumatic liquid booster pump, high pressure and stable output pressure.

All high pressure valves, pipelines and joints are made of stainless steel.

The clamping table adopts the three claws type, with stable output force and uniform pressure distribution Low maintenance expense.

Main functions and characteristics:

(1) This equipment has advanced design principle, with air driven liquid pump as its clamping pressure source and air driven gas booster as its test pressure source. It is equipped with a gas cylinder, which can conduct the test continuously.

(2) The test pressure is adjustable and the rate of pressure rise is settable.

(3) The clamping pressure source and the test pressure source use imported booster pumps from America or Germany. They have a wide output pressure range.

(4) All the high pressure valves, pipe fittings and connectors are imported from abroad, to ensure their pressure level, safety and reliability. Most gas or liquid media are applicable.

Range of application: Test the set pressure, setback pressure and tightness performances of direct loaded safety valves and pilot operated safety valves.
 

Safety valve test bench is used for various safety valve setting pressure adjustment, the whole set pressure detection, discharge pressure detection, back seat pressure testing, assessment of its pressure safety performance etc Main technical data for Manual/ Computer control safety valve test bench

The safety valve test bench system is mainly composed of power system, valve clamping system,  testing system, electrical control system.

Computer control system safety valve test bench equipment

Technical Parameters:

(1) Maximum drift diameter: DN400mm

(2) Maximum test pressure: 60 MPa

(3) Pressure test precision: Pressure gauge of 0.4 grades (More precise pressure gauge can be chosen.)

(4) Test medium: Nitrogen, compressed air or clean water (Medium with dual-use for gas or liquid can be produced.

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.
