Abstract
The utility model discloses a plug of a valve body, which comprises a plug body, wherein the side wall of the plug body is provided with external threads which are threadedly connected with the valve body; and the plug body is provided with a positioning structure for positioning a valve rod. The positioning structure comprises a boss arranged at the top end of the plug body; and a positioning hole matched with the valve rod correspondingly is vertically arranged in the boss. The plug has simple structure and good practical effect, the swing of the valve rod in the valve body is limited, the noise generation is effectively reduced, the sealing property between the plug and the valve body is good, and the reliability is high.
Description
Technical field
The utility model relates to control valve, particularly a kind of valve body plug of control valve.
Background technique
Some autocontrol valves in the market because valve rod is long, in the swing easily of valve body the inside, can have produced noise, and be difficult for sealing.
The model utility content
Problem to be solved in the utility model just provides a kind of valve body plug simple in structure, and the restriction valve rod can effectively reduce the generation of noise in the swing of valve body the inside, and good airproof performance.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of valve body plug, comprise the plug body, it is characterized in that: on plug body sidewall, be provided with the outside thread that is threaded with valve body, on the plug body, be provided with the position structure of location valve rod.Employing is threaded, and is simple, good airproof performance.
Further, described position structure comprises the boss that is located at plug body top, vertically is provided with the positioning hole with the valve rod corresponding matching in the boss.
Further, be provided with a cross through hole in the described boss.When there were foreign material the valve the inside, foreign material can flow through from cross through hole, do not influence the circulation of valve body after making the plug body and valve rod being connected as far as possible like this.
Further, the plug body of described outside thread lower end is provided with the annular groove of embedded sealing ring.Sealing when increase seal ring assurance valve body plug is connected with valve body.
After adopting technique scheme, the utlity model has following advantage: structure is very simple, and good practical effect not only limits valve rod in the swing of valve body the inside, can effectively reduce the generation of noise, and and valve body between good airproof performance, the reliability height.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of embodiment's of the utility model an entity structure schematic representation;
Fig. 2 is a sectional view embodiment illustrated in fig. 1;
Fig. 3 is a schematic representation in actual applications embodiment illustrated in fig. 1.
Embodiment
A kind of embodiment's of the utility model structural representation as illustrated in fig. 1 and 2, a kind of valve body plug, comprise plug body 1, on plug body sidewall, be provided with the outside thread 2 that is threaded with valve body, on the plug body, be provided with the position structure of location valve rod 9, described position structure comprises the boss 3 that is located at plug body top, vertically is provided with the positioning hole 4 with the valve rod corresponding matching in the boss.
In the foregoing description, be provided with a cross through hole 5 in the boss, when there were foreign material the valve the inside, foreign material can flow through from cross through hole, do not influence the circulation of valve body after making the plug body and valve rod being connected as far as possible like this.On the plug body of outside thread lower end, be provided with the annular groove 6 of embedded sealing ring, guarantee the sealing when the valve body plug is connected with valve body.As shown in Figure 3, present embodiment is applied in the four-hole three-way valve.
The utility model structure is very simple, and good practical effect not only limits valve rod in valve body the inside swing, can effectively reduce the generation of noise, and and valve body between good airproof performance, the reliability height.
Except that above preferred embodiment, the utility model also has other mode of execution, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
