Claims

SUMMARY OF THE INVENTION 1, A VALVE comprising a cf housing with a saddle located in the flow part 15 of the housing cavity; a locking member, the stem of which is threaded at the end and provided with sealing elements. a flywheel with external and internal threads of the opposite direction interacting with the threads on the stem and body, characterized in that in the flow part of the body cavity the cylindrical bore is made with an eccentricity relative to the axis of the rod g, and placed

5 g

0

, nom in the flowing part of the end of the rod is made a section of a cylindrical surface, coaxial with the bore and located with

j the possibility of its interaction with the surface of the bore

2. The valve according to claim 1, characterized in that the flywheel is provided with a removable stop cooperating with the end face of the threaded end of the stem when the valve is opened.

3. A vent according to claims 1 and 2, characterized in that the removable stop is made in the form of a threaded plug with a diameter equal to the diameter of the threaded end of the stem.
