Water jacket and air bag type sealing device for hydraulic test of air bottle outside measuring method

Abstract

The invention relates to a water jacket and air bag type sealing device for hydraulic test of an air bottle outside measuring method, in particular to a test container for forming seal between a water jacket and a water jacket cover. The sealing device mainly comprises a pressure test joint, the water jacket cover, a pneumatic joint, a flange, a rubber air bag, a connecting flange and the water jacket, wherein the pressure test joint is fixedly connected with the water jacket cover through a connecting bolt and an O-shaped ring which seals the connecting part; the pneumatic joint is fixedly connected to an outer circular face of the connecting flange; the rubber air bag and the connecting flange are placed between the flange and the water jacket and fixed through the connecting bolts; and the connecting faces of the connecting flange, the flange and the water jacket are sealed through an upper end face and a lower end face of the rubber air bag. The sealing device has a simple, compact and reasonable structure, has simple and convenient operation, is quick, effective and reliable to form a water jacket seal, can ensure smooth hydraulic test of the air bottle outside measuring method, and greatly improves the production efficiency.

Description

technical field [0001] The invention relates to a water jacket airbag type sealing device for a water pressure test of a gas cylinder external measurement method, in particular to a test container for forming a seal between a water jacket and a water jacket cover. Background technique [0002] When carrying out external measurement method hydrostatic test (hereinafter referred to as the test) to the gas cylinder, the sealing form between the water jacket cover and the water jacket all adopts the form of the ring-shaped sealing ring plane seal. For this type of sealing structure, when testing, the water jacket cover needs to be pressed tightly on the water jacket to achieve the sealing effect. It is complicated to replenish water into the water jacket to exhaust air; moreover, because the flat ring-shaped sealing ring is easily damaged after being squeezed, the seal fails and leaks, so the ring-shaped sealing ring needs to be replaced frequently, and normal tests cannot be ca...

For this type of sealing structure, when testing, the water jacket cover needs to be pressed tightly on the water jacket to achieve the sealing effect. Supplement water into the water jacket to exhaust, the operation is complicated; moreover, because the flat ring-shaped sealing ring is easily damaged after being squeezed, resulting in seal failure and leakage, so the ring-shaped sealing ring needs to be replaced frequently, and normal tests cannot be carried out
