[0001] The utility model relates to the field of valve test benches, and more specifically, to a valve test bench. Background Art

[0002] The portable valve test bench is a device used to test the performance and working status of valves under various operating conditions. It can test and analyze the performance of valves such as opening and closing, sealing and flow by simulating the actual use conditions.

[0003] Common portable valve test benches usually include a main test bench body, a test control panel and a test gas source pipeline. In order to ensure that the top pressure sealing disc on the moving plate can quickly and well press against the valve flange for sealing, the moving plate is rigidly connected to the piston rod of the driving cylinder, and the top pressure sealing disc has a short stroke from contacting the valve flange to pressing the valve flange for sealing. Although it achieves the advantage of fast top pressure sealing, at the same time, because the top pressure sealing disc presses against the valve flange for a short stroke and has no buffer, the top pressure sealing disc directly presses against the valve flange. If it is not operated properly, it is easy to cause damage to the flange end face on the valve, affecting the normal use of the valve. Utility Model Content
