when the second moving plate 13 moves downwards, the pushing rod 804 is driven to move downwards through the connecting block 805, so that air temporarily stored in the air storage pipe 801 is extruded and enters the air bag 703 through the connecting pipe 802 and the hose 803, the air bag 703 is inflated and then abuts against the side wall of the valve body 12 to form a sealing effect, and therefore two ends of the valve body 12 can be sealed when the valve body 12 is inflated for testing, and testing accuracy is guaranteed;
when the test is required, the opening and closing member 1201 is closed, the air pump 602 is started, the electromagnetic valve 604 is opened, at the moment, the tested gas enters the air charging pipe 601 through the air supply pipe 603 and enters the right cavity of the valve body 12 after passing through the second mounting column 16, at the moment, the pressure of the right cavity is gradually increased, the pressure of the right cavity is tested through the second gas pressure sensor 17, the pressure of the left cavity is tested through the first gas pressure sensor 15, if the first gas pressure sensor 15 detects that the pressure of the left cavity is increased, the air leakage phenomenon exists in the opening and closing member 1201, the tightness of the air leakage phenomenon is disqualified, and therefore the detection of the tightness of the valve body 12 is more convenient, the efficiency is higher, and the accuracy of the test is ensured;
and when the inflation test is carried out, when gas enters the inflation tube 601, the gas also enters the fixed cylinder 901 and pushes the piston 902 and the moving rod 903 to move upwards, when the impact test is carried out on the valve body 12, the electromagnet 1005 is powered off, at the moment, the electromagnet 1005 does not attract the balancing weight 1004, the balancing weight 1004 moves downwards under the action of gravity and impacts the top of the moving rod 903, so that the moving rod 903 and the piston 902 move downwards, and the gas in the fixed cylinder 901 is rapidly extruded into the right cavity of the valve body 12 through the inflation tube 601, so that the gas rapidly impacts the opening and closing member 1201, and the influence caused by the water hammer phenomenon of the valve body 12 when the valve body 12 is closed is simulated, thereby the test effect is better.
