Referring to fig. 1-3, a device for detecting the sealing performance of a gas self-closing valve comprises a sealed transparent cup body 1, wherein the inner cavity of the sealed transparent cup body 1 is filled with purified water 2, and the top of the sealed transparent cup body 1 is fixedly connected with an air outlet pipe 3 and an air inlet pipe 4 in a penetrating manner respectively;
the bottom of the air inlet pipe 4 extends to the inner cavity of the purified water 2;
the air outlet pipe 3 is positioned at the top of the purified water 2, and the connection parts of the surfaces of the air outlet pipe 3 and the air inlet pipe 4 and the sealed transparent cup body 1 are subjected to sealing treatment;
when in use, the device is divided into two parts, namely inner sealing detection and outer sealing detection;
the inner seal is shown in figure 2: the input fixed air source comprises: 0.2Mpa, 0.6Kpa, 15 Kpa; the leak detector, the tested product clamping device, the reversing valve and other components.
The operation implementation process comprises the following steps:
the 0.2Mpa air source controls to transmit pressure air to the cylinder through the 2-position reversing valve, thereby clamping the tested product.
After a tested product is clamped, the gas is controlled by a 3-bit reversing valve 2, and 0.6Kpa pressure gas is input to supply gas to the tested product through a leak detector;
when the product is airtight, the leak detector tends to be static when the air pressure at the inlet and outlet of the leak detector is balanced;
when a product leaks, the air pressure at two sides of the leak detector cannot reach balance, and bubbles can be continuously generated by the leak detector;
supplying gas to a tested product through a leak detector to input 16Kpa pressure gas through a 3-bit reversing valve 2;
when the product is airtight, the leak detector tends to be static when the air pressure at the inlet and outlet of the leak detector is balanced;
