Claims

[Scope of utility model registration request]

A pressure vessel, a lid that closes the opening of the pressure vessel, a blind groove provided on the joint surface of either the pressure vessel or the lid, and a sealing agent injected into the groove attached to the lid. The check valve consists of a sphere that opens and closes the injection port, an intermediate member that contacts the sphere, and a helical spring that elastically presses the sphere toward the injection port via the intermediate member. in the valve body, and the intermediate member is provided with a flow path that guides the sealing agent to be injected into the inner cavity of the helical spring and has a cross-sectional area equal to or larger than that of the injection port. Joint sealing device.
