Automatic Safety Valve Test System
Automatic Safety Valve Test System is applied for various full-open, WeChat-style high, medium and low-pressure safety valves with diameters DN15~DN500 and pressure MAX.70MPa to test the trip pressure (also called opening pressure and setting pressure) and return pressure. and sealing and other performance tests
The fully automatic safety valve inspection bench uses an offline simulated safety valve working environment and is fully automatically controlled by a computer. It consists of a gas/liquid boosting system, a pressure control system, a hydraulic clamping table, a computer control system, a camera system (optional), etc. It integrates hydraulics, machinery, electrical appliances, software, control, and data processing, and has the advantages of reasonable structure, complete functions, stable performance, and high degree of digitalization.
The equipment is managed and produced in strict accordance with the SO 9001 quality management system based on our company's many years of production of valve testing equipment technology.
Products comply with GB/T 12241, GB/T 12242, GB/T 12243, GB/T 32291, TSG ZF001, API527 and other executive standards

Features:
The high-precision pressure regulating valve regulates the output pressure, and the test process is manually controlled through the button switch on the control cabinet ;
Automatic hydraulic clamping system, the workbench adopts the form of three claws, the output force is stable and evenly distributed, which facilitates the quick installation and positioning of the valve. The clamping pressure source adopts a booster pump imported from the United States, and the pressure head can automatically compensate for pressure to ensure the pressure test process. Stabilize the pressure of the system and prevent the safety valve from loosening,
All high-pressure valves, pipe fittings and joints are made of SUS 316 L material imported from the United States. The system uses weldless connections and cone seals, which are suitable for the sealing requirements of most hydraulic systems, ensuring pressure resistance levels, safety and reliability;
This uses imported high-quality pneumatic liquid booster pumps and pneumatic gas booster pumps. It uses pneumatic booster technology to stabilize and maintain stable pressure without fluctuations, and the output pressure is adjustable:
As well as imported high-quality pneumatic components, ultra-high-pressure valves, pipe fittings, and joints are made of high-quality HIP products imported from the United States.
Use pressure gauges above level 0.4 and provide pressure gauge distribution of different ranges to improve detection accuracy;
The automatic pressure acquisition system is used to detect the opening pressure and has overpressure, timeout and leakage monitoring functions, which can automatically alarm and terminate the test:
Automatic collection and monitoring system functions. (optional)
