Abstract
The utility model discloses an internal thread ball valve, comprising a valve body, a valve cover, a valve rod, a ball and a handle, wherein the valve body is an internally threaded valve body; the valve cover is an internally threaded valve cover; one end of the valve cover is inserted into the valve body; the valve body and the valve cover form an internal cavity for containing the ball; the inlet/outlet of the internal cavity runner is an internally threaded connecting port; the contact surface between the ball and valve body and the contact surface between the ball and the valve cover are respectively provided with a sealing ring. By using internal thread ball valve, the valve body is an internally threaded valve body and the valve cover is an internally threaded valve cover; after the valve body and the valve core are combined, the inlet/outlet of the internal cavity runner is used as an internally threaded connecting port, so the ball valve can be connected with external connecting pieces by screw thread without adding a connecting flange at the inlet/outlet of the internal cavity runner, therefore the production cost is reduce and the structure of the ball valve is simpler and more compact.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of internal thread ball valve.
Background technique
Ball valve is present widely used a kind of valve, its spheroid is located in the body cavity runner, the inner chamber runner offers can be for the import and export of medium turnover, but existing ball valve, in order to be connected with joint outer part, usually special adpting flange end face is set in the import and export of its medium, such structure setting not only makes ball valve increase the moulding difficulty in manufacturing, and improved cost of production, bring unnecessary economic burden.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of simple in structure, internal thread ball valve that cost of production is lower.
For achieving the above object, the utility model provides a kind of internal thread ball valve, include valve body, valve gap, spheroid, valve rod, handle, wherein said valve body is tapped valve body, described valve gap is tapped valve gap, one end inserting of valve gap is in valve body, and valve body and valve gap constitute the inner chamber that can hold spheroid, and the import and export of inner chamber runner are tapped connecting port.
The beneficial effects of the utility model are: because ball valve provided by the utility model, its valve body is tapped valve body, valve gap is tapped valve gap, after valve body and the valve gap combination, the import and export of its inner chamber runner are tapped connecting port, so when ball valve is connected with joint outer part, can be by being threaded, needn't reduce cost of production effectively at the adpting flange of setting up of the import and export of inner chamber runner, also make the structure of ball valve become more simple compact.
The utility model can further be set to be equipped with seal ring on the surface of contact of described spheroid and valve body and on the surface of contact of spheroid and valve gap.
The utility model also can further be set to described valve rod one end and be located in the valve body and the spheroid interlock, is equipped with handle on the valve rod the other end, be provided with stuffing box packing and fastening screw nut between valve rod and the valve body, and described fastening screw nut is located at the outside of stuffing box packing.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model.
Embodiment
Provided a kind of internal thread ball valve as shown in Figure 1, include valve body 1, valve gap 2, spheroid 3, valve rod 4, handle 5, wherein said valve body 1 is tapped valve body 1, described valve gap 2 is tapped valve gap 2, one end inserting of valve gap 2 is in valve body 1, valve body 1 constitutes the inner chamber that can hold spheroid 3 with valve gap 2, and the import and export 6 of inner chamber runner are tapped connecting port 6, and be provided with pad 7 between described valve gap 2 and the valve body 1, be equipped with seal ring 8 on the surface of contact of described spheroid 3 and valve body 1 and on the surface of contact of spheroid 3 and valve gap 2, described valve rod 4 one ends are located in the valve body 1 and link with spheroid 3, be equipped with handle 5 on valve rod 4 the other ends, be provided with stuffing box packing 9 and fastening screw nut 10 between valve rod 4 and the valve body 1, and described fastening screw nut 10 is located at the outside of stuffing box packing 9.
