Claims

[Scope of utility model registration request]

In a type of valve in which a ring-shaped valve seat is arranged between the valve element of the valve body and the valve element is rotated to open and close the fluid passage while maintaining airtightness by crimping the valve element, the valve, and the seat. An annular groove is formed in the crimped surface of the valve seat that is crimped to the valve element, and in the center, and a passage communicating between the annular groove and the outside of the valve seat is formed inside the valve seat, and is provided on the valve body. forming a passage in the valve body that communicates the sealant injection part with the passage in the valve seat;
A valve characterized in that the sealant injected from the injection part is introduced into an annular groove provided on a crimping surface of the valve seat when necessary.
