A large valve and a small valve having a small valve seat formed on the large valve body on which a small valve body is seated are arranged in series with each other in the conduit, A valve stem is slidably disposed in the main body, and the valve stem is provided at one end with a protrusion that penetrates the valve seat and opens and closes the small valve body, and a locking part that opens and closes the large valve body, A nozzle gun comprising a lever that is swingably attached to the main body and is slidably operated by coming into contact with the other end of the valve stem.

Claims

[Scope of utility model registration request]

A large valve whose main body is provided with a conduit whose base end communicates with a pressure source and whose distal end is fitted with a nozzle or the like, and which forms a large valve seat on which a large valve body is seated; A small valve having a small valve seat on which a small valve body is seated is disposed in parallel with each other in the pipeline, and the small valve is inserted through the large valve seat of the large valve body. A valve stem is slidably disposed on the main body, and has a protruding part for opening and closing the valve body and a locking part for opening and closing the large valve body, each at one end thereof. A nozzle gun comprising a lever that is swingably attached to the main body and is slidably operated when brought into contact with the lever.
