[ background of the invention ]
As is well known, the failure of the sealing performance of the valve body in the production process directly affects the service performance of the product, so the sealing performance is required before the product is put on the market. The existing method for detecting the sealing performance is to charge a certain pressure of gas into a valve, and then observe whether bubbles are generated in water to judge whether leakage exists or not, for example, the method is as follows: CN201110061652.2 discloses a safety valve seal detector, whether there is the bubble to produce in order to confirm the leakproofness of the safety valve of examining through observing the leakage detector, but when this kind of detector detected the safety valve, if under the condition that has leak or trachoma on the safety valve body, gaseous leak or trachoma position on through the valve body were discharged, and the combustion gas can not enter into the aquatic and form the bubble, leads to the leakproofness of unable accurate observation valve body.
The utility model discloses it is not enough to provide to study to prior art promptly.

The valve that will wait to detect is placed on the connecting seat, press the button, the piston rod extension on the cylinder, the end cap descends to fix the valve on the connecting seat, it aerifys to give the valve through the air pump, it is gaseous to reach valve bottom position through the intake pipe, later through outlet duct to pressure measurement appearance position, the mercury column height through mercury barometer confirms gas pressure, and pressurize a period, during atmospheric pressure keeps, mercury height is unchangeable, valve seal satisfies the requirement, valve position atmospheric pressure is detected through mercury barometer, and during the leakproofness test, the mercury column height is unchangeable, can directly perceived confirmation valve seal, and set up and observe atmospheric pressure through mercury barometer, mercury density is big, can fill great atmospheric pressure, the leakproofness of detection valve that can be more accurate.
Preferably, a relay is further fixed on the workbench. The relay is a time relay, and the pressure maintaining time can be confirmed.
Preferably, a counter is further fixed on the workbench. The number of valves that have been detected is confirmed by a counter.
Preferably, the workbench is also provided with a pressure regulating meter. The air pump is connected with the connecting seat after being connected with the pressure regulating valve of the pressure regulating meter, and the air pressure for pressure maintaining during valve detection is regulated through the pressure regulating valve, and the tightness can be confirmed by comparing the pressure regulating meter with the mercury barometer.
Compared with the prior art, the utility model has the advantages that:
detect valve position atmospheric pressure through mercury barometer to during the leakproofness test, mercury column height is unchangeable, and the valve leakproofness of confirming that can be directly perceived, and set up and observe atmospheric pressure through mercury barometer, and mercury density is big, can fill into great atmospheric pressure, the leakproofness of detection valve that can be more accurate.
