The experimental component 500 includes a water storage tank 501 fixedly arranged on the side surface of the L-shaped mounting seat 100, and a high-pressure water pump 502 arranged on the upper surface of the water storage tank 501.

[0038] A liquid inlet pipe 503 extending to the upper surface of the lifting plate 301 is embedded in the inner top wall of the upper positioning plate 303, and a through hole 504 for the liquid inlet pipe 503 to slide is opened on the upper surface of the lifting plate 301. An electronic pressure gauge 505 is arranged on the outer surface of the liquid inlet pipe 503, which can facilitate the monitoring of the internal pressure of the valve.

[0039] The liquid inlet end of the high-pressure water pump 502 extends to the inner bottom of the water storage tank 501, and a hose 506 communicating with the liquid inlet pipe 503 is arranged at the liquid outlet end of the high-pressure water pump 502.

[0042] Embodiment Two

[0043] Based on Embodiment One, and different from Embodiment One,

[0044] A valve experimental device further includes:

[0045] A sealing assembly 400, which is used to seal the upper positioning disk 303 and the water inlet end of the valve. The sealing assembly 400 includes sealing grooves respectively opened on the opposite surfaces of the lower positioning disk 302 and the upper positioning disk 303, and a concave sealing gasket 401 is fixedly arranged on the inner wall of the sealing groove. The sealing assembly 400 further includes two corrugated airbag columns 402 fixedly arranged on the upper surface of the upper positioning disk 303, and the top ends of the corrugated airbag columns 402 are fixedly connected to the lower surface of the lifting plate 301. An annular installation groove is opened on the inner walls of the sealing groove and the concave sealing gasket 401 on the upper positioning disk 303, and an annular sealing airbag 403 is fixedly arranged on the inner wall of the annular installation groove. Inflation pipes 404 extending into the annular sealing airbag 403 are embedded in the inner bottom walls of the two corrugated airbag columns 402;

[0046] A tightening return spring 405 is fixedly arranged on the inner top wall of the corrugated airbag column 402, and the bottom end of the tightening return spring 405 is fixedly connected to the inner bottom wall of the corrugated airbag column 402, which is convenient for the reset of the corrugated airbag column 402 and the annular sealing airbag 403 after the detection contact.

[0048] During operation, when the device conducts a pressure detection test on the valve, the valve can be placed on the upper surface of the L-shaped mounting base 100, and the water outlet pipe of the valve is inserted into the lower positioning disk 302. Then, the lifting motor 304 is started to drive the threaded column 305 to rotate. The rotation of the threaded column 305 drives the lifting plate 301 to move downward. The downward movement of the lifting plate 301 drives the upper positioning disk 303 to move downward and tightly abut against the top end of the water inlet pipe of the valve. Then, the high-pressure water pump 502 is started to pump the water in the water storage tank 501 through the hose 506 and the liquid inlet pipe 503 into the valve and then back to the water storage tank 501 through the return pipe 507. After that, the solenoid valve on the return pipe 507 is closed, and the internal pressure of the valve is observed through the electronic pressure gauge 505, so that the device can effectively experiment on valves of different specifications and heights. When the upper positioning disk 303 contacts the top end of the water inlet of the valve, the continuous downward movement of the lifting plate 301 will drive the upper positioning disk 303 to squeeze the two corrugated airbag columns 402, so that the gas in the corrugated airbag column 402 can enter the annular sealing airbag 403 and make it expand, so that it tightly abuts against the surface of the top end of the water inlet pipe of the valve, realizing an effective seal at the connection between the upper positioning disk 303 and the valve and ensuring the accuracy of the experimental data.
