Abstract
The invention relates to a butterfly valve shaft sleeve capable of being detached online. The butterfly valve shaft sleeve capable of being detached online comprises a valve body, wherein a through hole is formed in the middle of the valve body in the vertical direction, a valve rod is arranged in the through hole, the outer side of the valve rod is sleeved with a shaft sleeve which comprises a lower shaft sleeve body, the lower shaft sleeve body is of a cylindrical structure hollow inside, an integral connecting flange is arranged on the upper portion of the lower shaft sleeve body, a sealing ring groove is formed in the lower shaft sleeve body, a plurality of sealing ring grooves are formed in the outer surface of the lower shaft sleeve body, and the connecting flange is provided with at least two round through holes and two threaded through holes. The butterfly valve shaft sleeve capable of being detached online has the advantages that the shaft sleeve is of an integral structure, when loss of a valve shaft sleeve sealing ring is caused, the valve shaft sleeve sealing ring can be maintained on a pipeline while a whole valve does not need to be detached, the shaft sleeve can be easily removed out of the valve body by pushing and pulling a threaded rod, and the valve can be used while the sealing ring is replaced with a new one and the new one is installed.
Description
technical field:
The present invention relates to one and can dismantle butterfly valve shaft sleeve online, belong to machinery valve field.
background technique:
Current butterfly valve shaft sleeve is on the market axle sleeve and flange separated type, only consider easy for installation, if day rear axle housing seal ring loss after, just can must keep in repair after the dismounting of whole butterfly valve when valve rod upper end is revealed, and the dismounting of barrel-type conventional bushings is extremely inconvenient.
summary of the invention:
Technical problem to be solved by this invention is: provide one can dismantle butterfly valve shaft sleeve online, just can change the seal ring on butterfly valve shaft sleeve like this when keeping in repair very easily.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: one can dismantle butterfly valve shaft sleeve online, include valve body, described valve body center vertical direction is provided with through hole, and be provided with valve rod in described through hole, the outside of described valve rod is socketed with axle sleeve, described axle sleeve includes Lower shaft sleeve, described Lower shaft sleeve is the cylindrical structural of inner hollow, and the top of described Lower shaft sleeve is provided with the adpting flange of one, and described adpting flange is also the cylindrical structural of inner hollow.
In order to prevent liquid from oozing out from axle sleeve, further, the inside of described Lower shaft sleeve is provided with seal groove, and the outer surface of described Lower shaft sleeve is provided with many seal grooves.
In order to can be for convenience detach, more further, described adpting flange be provided with at least two manholes, two tapped through holes, described manhole and tapped through hole with the center line of adpting flange for the symmetrical uniform arrangement of symmetry axis.
Compared with prior art, usefulness of the present invention is: a kind of valve stem sleeve that the present invention relates to is structure as a whole, not needing to dismantle whole deck valve door when the loss of valve shaft housing seal ring can in the enterprising maintenance of pipeline, axle sleeve can be easy to remove in valve body by screw rod push-and-pull, change seal ring reinstall can recover valve use.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is plan view of the present invention.
In figure: 1, valve body; 2, through hole; 3, valve rod; 4, axle sleeve; 5, Lower shaft sleeve; 6, adpting flange; 7, seal groove; 8, manhole; 9, tapped through hole.
embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments: one can dismantle butterfly valve shaft sleeve online, include valve body 1, described valve body 1 center vertical direction is provided with through hole 2, valve rod 3 is provided with in described through hole 2, the outside of described valve rod 3 is socketed with axle sleeve 4, described axle sleeve 4 includes Lower shaft sleeve 5, described Lower shaft sleeve 5 is the cylindrical structural of inner hollow, the top of described Lower shaft sleeve 5 is provided with the adpting flange 6 of one, described adpting flange 6 is also the cylindrical structural of inner hollow, the inside of described Lower shaft sleeve 5 is provided with seal groove 7, the outer surface of described Lower shaft sleeve 5 is provided with many seal grooves 7, described adpting flange 6 is provided with at least two manholes 8, at least two tapped through holes 9, described manhole 8 and tapped through hole 9 with the center line of adpting flange 6 for the symmetrical uniform arrangement of symmetry axis.
During use, first seal ring is set in the seal groove 7 on axle sleeve 4, then axle sleeve 4 is set on valve rod 3, whole axle sleeve 4 is placed in valve body 1, together with axle sleeve 4 being fixedly attached to valve body 1 by manhole 8 with bolt, if seal ring breaks, to be bolted on tapped through hole 9, then down thread, bolt top is on valve body, axle sleeve 4 will be exited, thus seal ring can be changed easily, in maintenance process, not need to dismantle whole valve body so just can change seal ring easily.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
