Description
Technical field
The utility model relates to valve technology field more particularly to a kind of plug valve slide constructions.
Background technique
Bracing type plug valve is the rotary valve that closure member is plunger shape, makes valve by being rotated by 90 ° and moving up or down
Passway beyond the Great Wall communicates or is not communicated with the passway on valve body, a kind of valve opened or closed is realized, mainly by valve
Body, valve deck, cock, flap, valve rod and rail brackets etc. are constituted, and cock is connect with flap by dovetail configuration.Due to bracing type
Plug valve is chiefly used in that medium is truncated on pipeline, and flap dovetail and cock dovetail can inevitably precipitate the accumulation such as dregs in use process
Object, and the structure is unfavorable for blowdown at flap and cock cooperation, to flap card resistance even locking phenomenon occur, exists certain
Leakage probability, and then influence valve service performance and service life.
Utility model content
The utility model is intended to provide plug valve slide construction, can avoid bracing type plug valve flap and goes out with cock mating surface
Existing card resistance and locking.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows：
A kind of plug valve slide construction, including valve rod, flap, cock and valve body, flap and cock are arranged in valve body, valve
Bar one end is put in valve body to be connect with cock, and there are two flaps, and two flaps are respectively arranged on the two sides of cock, and flap and cock are logical
It crosses dovetail groove to connect with dovetail boss, there is passway in the cock, the sealing surface of the flap is spherical surface, the dovetail groove
Slot of cooling down is equipped at base angle, the slot of cooling down is through slot.
Further, the junction of the dovetail boss and shoulder is equipped with slot of cooling down.
Wherein, the dovetail boss is arranged in cock, and the dovetail groove is located on flap.
Further, sealing ring is equipped between the flap and valve body.
Wherein, the valve clack sealing surface is equipped with the annular groove for installing sealing ring, and the sealing ring is mounted on sealing
In circle.
Compared with prior art, the utility model has the advantages that：
1. the utility model increases slot of cooling down at flap and cock dovetail configuration, it is similar to machine ram, in certain journey
It is conducive to the guiding of flap on degree and moves up and down, prevents flap dovetail and cock dove-tail slide face excessively impaired；Simultaneously in dovetail
At structure increase cool down slot carry out blowdown, can anti-block, anti-lock, the service life of valve can be extended；
2. being equipped with sealing ring between flap and valve body, quickly and easily sealing function is realized；
3. the utility model is compact-sized and ingenious, filth-discharging effect is ideal, and sealing performance is reliable, runs smoothly and flexibly,
Installation and debugging are convenient.

Fig. 2 is the cross-sectional view of bowing of the utility model；
Fig. 3 is the partial enlarged view in Fig. 2 at I；
In figure：Cool down slot, 7- dovetail groove, 8- dovetail of 1- valve rod, 2- flap, 3- cock, 4- sealing ring, 5- valve body, 6- is convex
Platform.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown in Figure 1, 2, 3, plug valve slide construction disclosed by the utility model, including valve rod 1, flap 2,3 and of cock
Valve body 5, flap 2 and cock 3 are arranged in valve body 5, and 1 one end of valve rod is put in valve body 5 to be connect with cock 3, and there are two flaps 2,
Two flaps 2 are respectively arranged on the two sides of cock 3, and flap 2 is connect with cock 3 by dovetail groove 7 and dovetail boss 8, convenient for up and down
Guiding when sliding.There is passway in cock 3, the sealing surface of flap 2 is spherical surface, it is equipped with slot 6 of cooling down at the base angle of dovetail groove 7,
Slot 6 of cooling down is through slot；The junction of dovetail boss 8 and shoulder is equipped with slot 6 of cooling down, and slot 6 of cooling down plays the role of blowdown, makes to act suitable
Freely.Wherein, dovetail boss 8 is arranged in cock 3, and the slot 6 of cooling down in cock 3 runs through the top and bottom of cock 3；Dovetail groove 7
On flap 2, the slot 6 of cooling down on flap 2 runs through the top and bottom of flap 2.
It is equipped with sealing ring 4 between flap 2 and valve body 5, realizes quickly and easily sealing function.2 sealing surface of flap is equipped with
For installing the annular groove of sealing ring 4, sealing ring 4 is mounted in sealing ring 4.
The utility model solves valve deposits such as dregs on pipeline and in flap and cock mating surface is difficult to blowdown
Problem guarantees the effective blowdown of valve and flexible movements, improves the service performance of valve and extend the service life of valve.
Certainly, the utility model can also have other numerous embodiments, without departing substantially from the spirit of the present invention and its essence
In the case where, those skilled in the art can make various corresponding changes and modifications, but these according to the utility model
Corresponding changes and modifications all should belong to the protection scope of the utility model the attached claims.
