Abstract
The utility model discloses a compact plug valve, its technical scheme main points are compact plug valve, including valve body, the valve rod of mutually supporting, be equipped with the passageway that link up that supplies the medium to flow through on the valve body, with the crossing conical valve pocket of passageway still locates the toper cock body that is used for opening and close in the valve pocket including the rotation, still be equipped with the elastic component between cock body and valve body base. The plug body is conical, and a tight effect is achieved by pushing the plug body upwards; and the leakproofness can not conveniently be adjusted in the rigid fit, consequently adopts the elastic component to make the cock body keep upwards conflicting the valve body, has guaranteed airtight effect, has guaranteed the elastic fit of valve body with the cock body simultaneously, and when the clearance appears in the cooperation of valve body and cock body upper end, the elastic component pushes up the effect that realizes the automatically regulated leakproofness with the cock body.
Description
Technical field
The utility model relates to a kind of valve, and more particularly, it relates to a kind of compact type stopcock.
Background technique
Because structure is simple, switch rapid, pressure drop is less, stopcock is used widely within the specific limits.The basic structure of existing stopcock comprise valve body, valve rod, the cock body be connected with valve rod, for rotating the component such as the handwheel of cock body.Its basic principle rotates to location place for operating handwheel, and when the passage on cock body is just to import and export, stopcock is in opening state.When the passage on cock body and the import and export passage on valve body in 90 ° time, stopcock is in closed condition.
At present, stopcock disclosed on market, often the matching relationship of valve body and cock body is that rigidity is connected, and sealing effect is poor, and the sealing of cock body and valve body is easily influenced, further causes medium surprisingly to circulate, causes adverse consequences.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of sealing good compact type stopcock.
For achieving the above object, the utility model provides following technological scheme: a kind of compact type stopcock, comprise the valve body, the valve rod that cooperatively interact, described valve body is provided with the through passage flow through for medium, with the valve pocket of the taper of described passages intersect, also comprising the taper cock body for opening and closing rotating and be located in valve pocket, between described cock body and valve base, being also provided with elastic component.
The utility model is set to further: described cock body is provided with the annular groove storing grease.
The utility model is set to further: described elastic component comprises disc spring.
The utility model is set to further: described cock body and valve body cooperation place are provided with and flow into for medium the guiding groove making cock body have the trend of moving upward.
The utility model is set to further: described cock body is provided with through hole, and described through hole is communicated with guiding groove and cock body inner chamber.
The utility model is set to further: be provided with low-leak type filler between described valve rod and valve body, and described valve rod is provided with O type circle, is marked with grease outside described O type circle.
Compared with prior art, the utility model has the advantage of: cock body is taper, realizing tight effect by upwards being pushed away by cock body; And rigidity cooperation can not facilitate to obtain regulating seal property, therefore adopt elastic component that cock body is kept up conflict valve body, ensure that obturation effect, ensure that the resilient engagement of valve body and cock body simultaneously, valve body and cock body upper end coordinate there is gap time, elastic component realizes the effect of automatic regulating seal property by cock body pushes away.

Embodiment
Referring to figs. 1 through Fig. 4, a kind of compact type stopcock of the utility model embodiment is described further.
A kind of compact type stopcock, comprise the valve body 1, the valve rod 2 that cooperatively interact, valve body 1 is provided with the through passage 11 flow through for medium, the valve pocket 12 of the taper crossing with passage 11, also comprising the taper cock body 3 for opening and closing rotating and be located in valve pocket 12, between cock body 3 and valve body 1 base, being also provided with elastic component 5; Cock body 3 is tapers, therefore cock body 3 is upwards pushed away realizing tight effect; Elastic component 5 achieves the elastic packing of cock body 3 and valve body 1, achieve better self-regulating function compared to rigid seal, in a practical situation, elastic component 5 is upwards compensated by resilient force cock body 3 and coordinates space, automatically adjust timely in real time, easy to use.
As shown in Figure 3, cock body 3 is provided with the annular groove 4 storing grease; In use, the gap of the grease in annular groove 4 to cock body 3 and valve body 1 cooperation place compensates timely, improves the sealing effect of cock body 3.
As shown in Figure 2, elastic component 5 comprises disc spring 51, disc spring 51 has the trend of upwardly cock body 3, be different from traditional rigidity to coordinate, this elastic structure can supplement matching gap in time, ensure that valve body 1 seals stability, achieve the sealing effect automatically regulating cock body 3 and valve body 1, and the structure of disc spring 51 also achieves the effect of damping, powerful buffering.
Described cock body 3 is provided with valve body 1 cooperation place and flows into for medium the guiding groove 32 making cock body 3 have the trend of moving upward; After interior media circulation, first through passage 11, further flow to cock body 3 again and lead to guiding groove 32, pressure medium in guiding groove 32 produces active force upwards and promotes cock body 3, ensures that it coordinates closely, and so the flow velocity of medium, flow are larger, the pressure produced is also larger, the sealing effect realized is better, and adjustment automatically in real time, easy to use.
Preferably, cock body 3 is provided with through hole 31, through hole 31 is communicated with guiding groove 32 and cock body 3 inner chamber, cut-out tap valve, and medium imports cock body 3 inner chamber by through hole 31, during work, medium produces larger pressure to cock body 3 outer wall, and after inner chamber is full of medium, the medium of circulation ensure that the balance of pressure difference inside and outside cock body 3, avoid pressure medium to cross ambassador's cock body 3 and be out of shape, improve working life and the ability of anti-deformation of cock body 3.
Low-leak type filler 6 is provided with between described valve rod 2 and valve body 1, described valve rod is provided with O type circle 7, is marked with grease outside described O type circle 7, and the grease that high pressure injects achieves further sealing effect to O type circle 7, triple seal designs, and meets the function of the low leak-testing of helium leak check.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
