The filler side of the being generally filler and unilateral V-type for occurring the packing seal position use of the valve rod of ball valve in the market are filled out
Expect to seal, leakage would tend to occur, some pollutions are brought to environment.
Utility model content
The purpose of this utility model is to provide a kind of ball valve of flexible filler pressing sleeve, to provide good sealing
Energy.
To achieve these goals, the technical solution adopted in the utility model is：A kind of ball of flexible filler pressing sleeve
Valve, including valve body and valve rod, set between the valve body and valve rod and gland are set on filler, filler, the gland
Filler pressing sleeve is set between filler, it is characterised in that：The filler pressing sleeve is elastic filler gland, and filler pressing sleeve is in stem shaft
Can occur to set on elastic deformation, the gland in screwed hole corresponding with filler pressing sleeve, screwed hole provided with top to direction
The compression adjusting screw of filler pressing sleeve upper end.
The utility model is further arranged to, and the upper side of the filler pressing sleeve is intilted inclined-plane, filler pressure
One annular groove is set on the lateral wall of set.
The utility model is further arranged to, and the filler pressing sleeve is located at part on the upside of annular groove to filler pressing sleeve
Outside is extended with compressing the abutting part that adjusting screw offsets, and gland is provided with the deformation sky deformed upon for abutting part
Between.
The utility model is further arranged to, and a ring annular groove is set on the madial wall of the filler pressing sleeve, and should
Annular groove is set through the upper side of filler pressing sleeve.
The utility model is further arranged to, and the filler pressing sleeve is made up of hard rubber material.
The utility model is further arranged to, and elastic bone corresponding with its deformation direction is provided with the filler pressing sleeve
Frame.
The beneficial effects of the utility model：The ball valve of flexible filler pressing sleeve provided by the utility model, it passes through
Flexible filler pressing sleeve is set between filler and gland so that filler can form elasticity between valve rod and valve body
Sealing, to reach good sealing effectiveness.

Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.
The utility model is illustrated below with reference to Fig. 1 to Fig. 3.
A kind of ball valve of flexible filler pressing sleeve, including valve body 1 and valve rod 2, are set between the valve body 1 and valve rod 2
Gland 4 is set on filler 3, filler 3, filler pressing sleeve 5, the filler pressing sleeve are set between the gland 4 and filler 3
5 be elastic filler gland, filler pressing sleeve 5 the axial direction of valve rod 2 can occur on elastic deformation, the gland 4 set with
Provided with the compression adjusting screw 6 for heading on the upper end of filler pressing sleeve 5 in the corresponding screwed hole of filler pressing sleeve 5, screwed hole.In above-mentioned setting
The elastic force that filler pressing sleeve 5 applies to filler is can adjust by compressing adjusting screw 6, the work of control and regulating seal property energy is reached
With to adjust the elastic force that filler pressing sleeve 5 applies to filler according to pressure medium.
The upper side of filler pressing sleeve 5 is to set an annular recessed on inclined inclined-plane, the lateral wall of filler pressing sleeve 5 on the inside of it
Extend to the outside of filler pressing sleeve 5 with compressing adjusting screw 6 groove 7, the part that the filler pressing sleeve 5 is located at the upside of annular groove 7
The abutting part 8 offseted, gland 4 is provided with the deformation space 9 deformed upon for abutting part.The inner side of the filler pressing sleeve 5
One ring annular groove 10 is set on wall, and the annular groove 10 is set through the upper side of filler pressing sleeve 5.
The filler pressing sleeve 5 provided in above-mentioned technical proposal its by compress adjusting screw 6 top pressure when, filler pressing sleeve 5
Top can be deformed upon into deformation space 9 and annular groove 7, because abutting part 8 extends out to the outside of filler pressing sleeve 5
Part, so filler pressing sleeve 5 can also be deformed upon to its inner side direction, such filler pressing sleeve 5 will be applied to its downside and inner side
Plus elastic force so that filler plays good sealing function between valve rod and valve body.
Filler pressing sleeve 5 is made up of hard rubber material, and elasticity corresponding with its deformation direction is provided with the filler pressing sleeve 5
Skeleton 11, elastic skeleton 11 plays a part of improving the deformation restoring force of filler pressing sleeve 5, filler pressing sleeve 5 is had longer use
Life-span.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification, above-mentioned vacation can also be made
If these improvement and modification also should be regarded as protection domain of the present utility model.
