Abstract
The utility model discloses a but valve rod packing seal of self compensating, it includes the filler base, filler base suit is on the valve rod, a plurality of V types are filled sealedly to filling the base location suit on the valve rod, fill the bush setting and fill sealed top and suit on the valve rod in the V type, compression spring press the top of filling the bush and suit on the valve rod, install the gland on compression spring's top, the gland passes through bolt fixed mounting on the valve body. This seals has from compensation function, can guarantee that sealing of valve rod still has fine sealed effect after dismantling wearing and tearing, reduce the possibility that the valve rod leaked to the work load of maintaining has been reduced.
Description
Technical field
The utility model relates to valve stem seal technical field, and particularly relating to one can self-compensating stem packing sealing.
Background technique
Existing valve rod sealing, in repeatedly disassembling section process, packing seal will be worn and torn, thus easily cause valve stem seal place to leak, in long-play process, needing often leaks to valve rod processes, valve maintenance workload will be increased, adds additional the work load of staff.Need development and Design novel valve stem to be filled with a sealing based on above-mentioned analysis thus reduce the burden that sealed valve stem water leakage phenomenon reduces efforts personnel.
Model utility content
The purpose of this utility model provides one self-compensating stem packing to seal, this sealing has self-compensating function, can ensure that being sealed in of valve rod carries out still having good sealing effect after dismounting is worn and torn, reduce the possibility that valve rod leaks, thus reduce the workload of maintenance.
In order to realize above-mentioned technical characteristics, the purpose of this utility model is achieved in that one can seal in self-compensating stem packing, it comprises filler base, filler base sheath is contained on valve rod, multiple V-type is filled with a sealing and is contained on valve rod by filling base setting sleeve, filled liner is arranged on top that V-type is filled with a sealing and is sleeved on valve rod, Compress Spring is pressed in the top of filled liner and is sleeved on valve rod, be provided with gland on the top of Compress Spring, gland is mounted by means of bolts on valve body.
Described filler base adopts polytetrafluoroethylmaterial material to make.
Described V-type is filled with a sealing and adopts polytetrafluoroethylmaterial material to make, and can be played sealing effect by compressive strain.
The quantity that described V-type is filled with a sealing is determined according to the degree of depth of filling letter.
Described filled liner and gland all adopt stainless steel material to make.
The utility model has following beneficial effect:
First filler base is fixedly mounted on valve rod in use, then multiple V-type is filled with a sealing and is accumulated in together by filling base location and installation on valve rod, again by filled liner, Compress Spring and gland are arranged on valve rod successively, finally by bolt, gland is fixed on valve body, by above-mentioned structural design, by Compress Spring V-type is filled with a sealing and compresses, it is made to be close on valve rod, play seal action, even if when one of them V-type is filled with a sealing generation wearing and tearing, other V-type is filled with a sealing and also can further compresses thus fit closely with valve rod under the action of the spring, play seal action.Thus, above-mentioned being filled with a sealing has auto-compensation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is sectional arrangement drawing of the present utility model.
Fig. 2 is the sectional view of the utility model filler base.
Fig. 3 is the sectional view that the utility model V-type is filled with a sealing.
Fig. 4 is the sectional view of the utility model filled liner.
In figure: filler base 1, V-type are filled with a sealing 2, filled liner 3, Compress Spring 4, gland 5, bolt 6, valve rod 7, valve body 8.
Embodiment
Below in conjunction with accompanying drawing, mode of execution of the present utility model is described further.
As Figure 1-4, one can seal in self-compensating stem packing, it comprises filler base 1, filler base 1 is sleeved on valve rod 7, multiple V-type is filled with a sealing and 2 is contained on valve rod 7 by filling base 1 setting sleeve, filled liner 3 be arranged on V-type be filled with a sealing 2 top and be sleeved on valve rod 7, Compress Spring 4 is pressed in the top of filled liner 3 and is sleeved on valve rod 7, be provided with gland 5 on the top of Compress Spring 4, gland 5 is fixedly mounted on valve body 8 by bolt 6.
Further, described filler base 1 adopts polytetrafluoroethylmaterial material to make.Filler base 1 is processed with the sphenoid surface that the V-type groove that is filled with a sealing 2 with V-type matches, thus serve V-type is filled with a sealing 2 supporting effect, guarantee compressive strain occurs simultaneously, play auto-compensation.
Further, the described V-type 2 employing polytetrafluoroethylmaterial materials that are filled with a sealing are made, and can be played sealing effect by compressive strain.By compressive strain can make V-type be filled with a sealing 2 both sides and valve body and valve rod are fitted closely, play seal action.
Further, described V-type be filled with a sealing 2 quantity determine according to filling the degree of depth of letter.Multiple V-type be filled with a sealing 2 superposition can play auto-compensation.
Further, described filled liner 3 and gland 5 all adopt stainless steel material to make.Adopt stainless steel material can extend the working life of sealing configuration.
Working principle of the present utility model is:
By the compressive force of Compress Spring 4, the V-type stacked is filled with a sealing and 2 carries out compressive strain, itself and the junction plane between valve body 8 and valve rod 7 are effectively fitted, play seal action, when V-type is filled with a sealing 2 generation wearing and tearing, also further can compress it, play auto-compensation, prevent water leakage phenomenon.
Advantage of the present utility model:
1, the working life that valve rod is filled with a sealing is extended.
2, the maintenance workload of valve is decreased.
Above-described embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
