Abstract
The utility model discloses a kind of soft sealing butterfly valve with gland, including valve body, the inner wall of valve body is rotatably connected to valve rod, is socketed with flap on valve rod.After upper seal and lower seal are worn, turn fastening bolt, due to the presence of elastic washer, it can guarantee that ladder gland carries out downwards micro-positioning regulators, and then compress upper seal and lower seal, so that upper seal and lower seal is generated radial deformation, adjusts the leakproofness of upper seal and lower seal；Upper seal and lower seal serious wear, when scrapping, ladder gland is moved up along valve rod, upper seal and lower seal can be separated in lap segment, it is removed, then new upper seal and lower seal are mounted on valve rod from lap segment, it is not necessary to upper seal and lower seal can also be installed by handwheel disassembly, it is time saving and energy saving；The hackle mark of the lap segment of upper seal and lower seal is intermeshed, and improves leakproofness.
Description
Technical field
The utility model relates to butterfly valve technical field more particularly to a kind of soft sealing butterfly valves with gland.
Background technique
Existing wafer type butterfly valve, the method that reply valve shaft leakage problem uses is: the mounting O-shaped between valve shaft and valve body
Circle or other kinds of sealing ring, under general working condition, this processing method can solve most valve shaft leakage
Problem.
But under the conditions of high temperature and pressure etc. is special or extreme operating condition, the sealing ring service life of existing soft seal form
It can greatly shorten, need to regularly replace O-ring, and the wafer type butterfly valve of existing assembly method needs to remove in replacement o circle
It installs O-ring after driving device or handwheel additional, or replaces O type circle after valve of dismantling.The mode of existing replacement o circle will obviously
The use cost of valve is significantly greatly increased, increases the meaningless amount of labour.Therefore, the prior art is defective, requires further improvement
With it is perfect.
Utility model content
Purpose of the utility model is to solve disadvantage existing in the prior art, and propose a kind of with gland
Soft sealing butterfly valve.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of soft sealing butterfly valve with gland, including valve body, the inner wall of valve body are rotatably connected to valve rod, are socketed on valve rod
There is flap, mounting base is connected at the top of valve body, the upper end of the valve rod through mounting base and is removably connected with handwheel, described
The top of mounting base be equipped with stepped groove, valve rod be located at one section in stepped groove be from top to bottom respectively sleeved on ladder gland under it is close
Seal, upper seal is socketed on ladder gland, and the ladder gland is connect by fastening bolt with mounting base.
Preferably, one section in the upper seal and lower seal is equipped with lap segment, and the opposite side of lap segment is equal
Equipped with hackle mark.
Preferably, elastic washer is equipped between the ladder gland and mounting base, elastic washer is socketed on ladder gland.
Preferably, the handwheel and valve rod are by hold-down bolt downlink connection, and handwheel is equipped with anti-skid chequer.
Compared with prior art, the utility model has the beneficial effects that
(1) after upper seal and lower seal are worn, fastening bolt is turned, due to the presence of elastic washer, can be protected
Card ladder gland carries out downwards micro-positioning regulators, and then compresses upper seal and lower seal, produces upper seal and lower seal
Raw radial deformation, adjusts the leakproofness of upper seal and lower seal；
(2) when scrapping, ladder gland is moved up along valve rod for upper seal and lower seal serious wear, can be incited somebody to action
Upper seal and lower seal are separated in lap segment, are removed, then by new upper seal and lower seal from lap segment
It is mounted on valve rod, it is not necessary to upper seal and lower seal can also be installed by handwheel disassembly, it is time saving and energy saving；
(3) the hackle mark intermeshing of the lap segment of upper seal and lower seal, improves leakproofness.
Detailed description of the invention
Fig. 1 be the utility model proposes structural schematic diagram；
Fig. 2 is part A structural schematic diagram in Fig. 1；
Fig. 3 is the structural schematic diagram of upper seal and lower seal.
In figure: handwheel 1, flap 2, valve body 3, valve rod 4, ladder gland 5, upper seal 6, fastening bolt 7, elastic washer 8,
Lower seal 9, hackle mark 10, mounting base 11.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of soft sealing butterfly valve with gland, including valve body 3, the inner wall of valve body 3 are rotatably connected to valve
Bar 4 is socketed with flap 2 on valve rod 4, and the top of valve body 3 is connected with mounting base 11, and mounting base 11 is run through in the upper end of the valve rod 4
And it is removably connected with handwheel 1, the top of the mounting base 11 is equipped with stepped groove, and valve rod 4 is located at one section in stepped groove by upper
It is respectively sleeved on ladder gland 5 and lower seal 9 under, upper seal 6 is socketed on ladder gland 5, the ladder gland 5 is logical
It crosses fastening bolt 7 to connect with mounting base 11, elastic washer 8, elastic washer 8 is equipped between the ladder gland 5 and mounting base 11
It is socketed on ladder gland 5, using the elasticity of elastic washer 8, fastening bolt 7 is facilitated to adjust ladder gland 5, and then compress upper close
Seal 6 and lower seal 9, the handwheel 1 passes through hold-down bolt downlink connection with valve rod 4, and handwheel 1 is equipped with anti-skid chequer, increases
Friction.
One section in the upper seal 6 and lower seal 9 is equipped with lap segment, and the opposite side of lap segment is equipped with saw
Groove 10 improves the leakproofness of lap segment using the engagement between two sides hackle mark 10, and then it is close under to improve upper seal 6
The whole leakproofness of seal 9.
In this case, after upper seal 6 and lower seal 9 are worn, fastening bolt 7 is turned, due to depositing for elastic washer 8
, it is ensured that ladder gland 5 carries out downwards micro-positioning regulators, and then compresses upper seal 6 and lower seal 9, makes 6 He of upper seal
Lower seal 9 generates radial deformation, adjusts the leakproofness of upper seal 6 and lower seal 9, and upper seal 6 and lower seal 9 are ground
Damage is serious, and when scrapping, ladder gland 5 is moved up along valve rod 4, can be by upper seal 6 and lower seal 9 in lap segment
It separates, is removed, be then mounted on new upper seal 6 and lower seal 9 on valve rod 4 from lap segment, it is not necessary to will
Upper seal 6 and lower seal 9 can also be installed by the disassembly of handwheel 1, time saving and energy saving, and upper seal 6 and lower seal
The hackle mark 10 of 9 lap segment is intermeshed, and improves leakproofness.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
