Title:
PRESSURE RESISTANCE INSPECTION DEVICE FOR VALVE
Document Type and Number:
WIPO Patent Application WO/2020/246592
Kind Code:
A1
Abstract:
Provided is a pressure resistance inspection device for a vehicle, in which while a space for inspecting leakage is set small to facilitate detection of search gas, external air is prevented from infiltrating into the space, so that leakage from a portion or the entirety of a test valve can be accurately inspected at once in a short time, and the pressure resistance of different test valves can be inspected continuously. The present invention comprises: a cover body 30 that encloses a portion or the entirety of a test valve 2 in an unsealed state; a gas sensor 12 that is mounted in a space S to be inspected inside the cover body 30; and an air curtain 40 that partitions and forms a communication area by which an external environment area T of the cover body 30 and the space S to be inspected of the cover body 30 communicate with each other, wherein the influence of the search gas inside the space S to be inspected due to atmospheric gas in the external environment area T is suppressed.
