safety valve calibration bench

       The safety valve calibration bench is a device that simulates the working environment of the safety valve off-line, and raises the internal pressure to the point where the safety valve takes off, and at the same time can display the take-off pressure of the safety valve through the pressure gauge on the device. It can verify the safety valve take-off pressure (also called opening pressure, set pressure) sealing test pressure. It is suitable for performance tests such as set pressure, reseating pressure and sealing performance of direct load and pilot operated safety valves. The design principle of the equipment is advanced, and the pneumatic liquid booster pump is used as the clamping pressure source, and the pneumatic gas booster pump is used as the test pressure source. The equipment is equipped with a gas cylinder, which can be tested continuously; The test pressure can be adjusted steplessly and boosted The speed can be set; Both the clamping pressure source and the test pressure source are booster pumps imported from the United States, and the output pressure range is wide; All high-pressure valves, pipe fittings and joints are made of 316 raw materials imported from the United States to ensure the pressure resistance level, safe and reliable , and suitable for most gas and liquid media. ·With power-off protection function, the system will automatically release the pressure after power failure to terminate the experiment, ensuring the safety of operators and equipment to the greatest extent. 1. It has a step-by-step pneumatic clamping structure according to different calibers and pressures; 2. It has a pressure switching mechanism based on the calibration pressure; 3. According to user needs, it can be equipped with a computer to display, print and store relevant data.
