Seal with gas leak detection function, high pressure gas container and gas leak monitoring system equipped with the same

摘要

The present invention relates to a seal capable of preventing gas outflow and at the same time detecting gas outflow, a high-pressure gas container having the same, and a gas outflow monitoring system for the high-pressure gas container. A seal having a gas leak detection function according to an embodiment of the present invention is installed between a first member and a second member coupled to each other to prevent gas leak and has a gas leak detection function for detecting gas leak, A seal plate installed between the first member and the second member to prevent gas leakage, and a gas detection unit configured on the seal plate to detect gas leakage, wherein the gas detection unit is from the inner periphery to the outer periphery of the seal plate. a gas inlet hole through which the gas flowing out between the first member and the second member is introduced, a gas pressure relief hole connected to the gas inlet hole to discharge the gas introduced into the gas inlet hole to the outside, the gas inlet hole a sensing plunger installed in a slidable manner to open and close the gas pressure relief hole by sliding in the gas inlet hole according to the pressure of the gas flowing into the gas inlet hole, and a gas installed in the sensing plunger and introduced into the gas inlet hole It includes a gas detection sensor for detecting the. Therefore, it is possible to sense the gas without damaging the container, and it is possible to prepare for a gas leakage accident.
