Abstract
The utility model relates to a throttle valve body which comprises a body. A concave face structure which is arranged by being matched with a valve element is arranged in the inner cavity of the body, a clamping groove is formed in the middle of the concave face structure, a rubber body is arranged in the clamping groove, the rubber body extends out of the clamping groove and is tightly attached to the concave face structure, and the concave face structure is arranged under the valve element. The throttle valve body has the advantages that the structure is simple, the clamping groove is formed in the middle of the concave face structure, the rubber body is arranged in the clamping groove, the valve element and the rubber body are mutually extruded, and good air impermeability is achieved.
Description
Technical field
The utility model relates to valve field, relates in particular to a kind of throttle valve valve body.
Background technique
Existing throttle valve generally is comprised of valve body, valve gap, valve rod, handwheel and spool, described valve gap is connected with valve seal and fixes, the valve gap center is equipped with valve rod, the lower end of valve rod is equipped with spool, spool is located between the import and outlet of valve body, spool can rotate with valve rod and move up and down, and is tightly connected with body cavity formation.At present, the spool of existing throttle valve and body cavity are steel and consist of, and its sealing is relatively relatively poor, causes the compact type between throttle valve valve body and the spool poor.
The model utility content
In view of this, be necessary to provide a kind of simple in structure, the throttle valve valve body of good airproof performance.
The utility model is achieved in that a kind of throttle valve valve body, comprises body, is provided with in the inner chamber of described body with spool to cooperate the concave structure of installing, and the middle part on the described concave structure is provided with draw-in groove, is provided with rubber body in the described draw-in groove.
Further, described rubber body extends to outside the draw-in groove, and is close to concave structure.
Further, described concave structure be located at spool under.
The advantage of a kind of throttle valve valve body that the utility model provides is: the utility model is simple in structure, is provided with draw-in groove by the middle part on concave structure, is provided with rubber body in the described draw-in groove, mutually pushes at spool and rubber body, reaches good tightness.
