Claims

[Scope of utility model registration request]

It has a valve housing and a movable valve inserted into the valve housing, and has a seat part at an inner end of a drain inlet communicating with a valve chamber in the valve housing, and a seat part and an inward part following the seat part. The movable valve has a conical tip that comes into close contact with the seat portion and a sealing material that comes into close contact with the inclined surface, and the movable valve is closed by a spring that makes the movable valve non-wetted with liquid. A liquid drain valve, which is connected to an operating member which is biased in a direction and is not in contact with liquid, and has a liquid drain outlet provided in a lower part of the valve casing to discharge the entire amount of liquid in the valve chamber.
