The test bench can be used to test various safety valves, such as spring direct load safety valves, power auxiliary safety valves, auxiliary loading safety valves, full open, micro open, flange, threaded safety valves, etc. The safety valve test bench is to use high-pressure air or nitrogen as a medium to test the sealing performance, jump pressure, recoil pressure, etc. of the safety valve, and is used for various safety valve setting pressure adjustment, setting pressure test, exhaust pressure test, rear seat pressure test, testing the pressure sealing performance of the safety valve, leakage rate. Our safety valve test benches have obvious advantages in terms of technology, test accuracy, safety and so on.

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. With the same valve size, TEREK products can test higher pressures; At the same pressure, TEREK products can test larger valve sizes; Our test benches provide faster and more precise clamping forces. Control panel with different gauges for reference.

3. The equipment is equipped with our own air-operated booster pump products, which can quickly establish the pressure and keep the pressure constant; Using high-pressure stainless steel needle valve, two-way installation, high pressure resistance, durable; 

4. Typically, we use a two-stage pneumatic high-pressure gas booster pump and a high-pressure air-driven liquid pump to build a safety valve test bench. We are able to provide better technical support, price and service to our customers.

5. It is used to test various relief valves such as full open, micro open, metric, flange and thread. The safety valve test bench is used for various safety valve setting pressure adjustment, complete set of pressure testing, exhaust pressure testing, rear seat pressure detection, and its pressure safety performance evaluation. It has obvious advantages in technology, test accuracy, safety and other aspects.

PRODUCT PICTURES: 

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

1)Power system:
Air drive gas or nitrogen booster pump, air driving pressure 2-8 bar; High pressure testing range: 0-400 bar for option; Provide high pressure for valve test.

2)Clamping system: 
The clamping system is powered by the 0-32mpa output pressure provided by the LDD40 hydraulic booster pump, and the clamping force fully meets the pressure requirements of the safety valve. The safety valve adopts the corresponding connecting fixture of the specification, and is connected with the high-pressure pump gas pipeline;

Cylinder pressure to ensure the sealing between the measured part and the pipeline, separate operation. The liquid booster pump provides high pressure power. Cylinder clamping ensures the sealing between the tested parts and the pipeline.

3)Test system:
Pressure range: 0-1MPA, 0-2.5 MPA, 0 -10 MPA, 0-25 MPA and 0-60MPA. The performance index is up to the accuracy of ± 1%FS, and the range ratio is 60:1 and 64:1.

4) Electrical control and output system:
Reliable and high quality electrical components ensure high efficiency of the testing process.
The main parts of the equipment are assembled in closed stainless steel cabinet or stainless steel frames.The pressure gauge, valve and pressure regulator will be mounted on the panel. The corresponding sign will also be marked on the panel.

WHY CHOOSE TEREK PUMP:
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
 

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.
