Claims

[Claims for Utility Model Registration] '(1) The valve casing 7 of the pressure check valve installed in the fluid passage communicating the pressure vessel and the pressure switch includes:
forming a hole through which the pressure chamber device and the pressure switch communicate, and an opening whose tip and end communicate with the hole, and a valve body comprising a stop valve body and an exhaust valve body is provided in the opening; The stop valve body can be opened and closed in the middle of the hole by external operation, and the exhaust valve body is also formed into a stop valve body by external operation, and the exhaust hole communicating with the hole can be opened to the atmosphere. A pressure check valve in a pressure vessel characterized by: (2) Claim 1 of the Utility Model Registration Claim, characterized in that the opening is configured to be tightly plugged with a removable blind lid, and configured to allow a pressure rise test adapter to be attached and detached. Pressure check valve in the pressure vessel described. (3) The stop valve body is screwed into the hole in a manner that allows it to move forward and backward freely by external operation and is airtightly screwed into the hole so that its tip can open and close the hole, and the exhaust valve body can be inserted into the exhaust hole by external operation. A pressure check valve for a pressure vessel according to claim 1 or 2, which is built into the stop valve body via a spring so as to be openable and closable.
