Abstract
The utility model discloses a wear -resisting knife gate, including valve body and flashboard, be equipped with the sealing strip with flashboard matched with in the valve body, the valve body includes left valve body and right valve body, a left side valve body and right valve body all inlay have with flashboard matched with valve body in the backing member, make the flashboard reciprocate in the valve body, the flashboard is inconsistent with the interior backing member of valve body, flashboard and the friction of valve body production metal, and the service life of the glass pump is increased, because the backing member has the elastic deformation characteristic in the valve body, when the flashboard compresses tightly the interior backing member of valve body, elastic deformation can take place for the backing member in the valve body, the flashboard of more closely laminating, can effectively improve the sealed of slide valve like this, the backing member was just passable in the backing member use took place to wear and tear and only need change the valve body alone in the valve body, long service life, and maintenance cost is reduced. The sealing strip includes the rubber layer of sealing strip body and parcel sealing strip body, and the sealing strip body adopts the metalwork for this sealing strip remains the high strength character of metal seal strip, and sealing strip and the friction of valve body production metal are also avoided to the rubber layer simultaneously, improve life.
Description
Technical field
This utility model is related to valve field, more specifically, it relates to a kind of wear-resisting knife gate valve.
Background technology
Also known as knife door lock valve, blade type Parallel Slide Valves, its opening and closing element is flashboard to knife gate valve, the direction of motion of flashboard and fluid side
To perpendicular, by medium being cut off with the knife-edge flashboard of cutting fiber material.Valve body not actually exists chamber, and flashboard exists
Lifting in side guide groove, and be pressed on valve seat by the lug of bottom, wherein sealing strip and flashboard are set in side guide groove
End face phase be adjacent to formation sealing, to ensure the sealing of knife gate valve.
In lifting process in side guide groove, the end face of flashboard is adjacent to valve body to the flashboard of wherein one-way sealing gate valve
Inner surface, but flashboard and valve body are all generally foundry goods and material hardness quite so that the contact surface of flashboard and valve body easily produces
Raw abrasion, reduces the sealing of gate valve, reduces the service life of gate valve.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of the resistance to of one-way sealing gate valve
Mill structure, can effectively reduce the contact surface abrasion of flashboard and valve body, improve service life.
For achieving the above object, this utility model provides following technical scheme:
A kind of wear-resisting knife gate valve, including valve body and flashboard, is provided with the sealing strip matching with flashboard in described valve body, described
Valve body includes left valve barrel and right valve barrel, and described left valve barrel and right valve barrel are all inlaid with the valve body inner piece matching with flashboard, valve
Internal backing member is made using having resilient nonmetallic materials, and described valve body inner piece is inconsistent with flashboard；
The mating surface of described left valve barrel and right valve barrel is equipped with the seal groove for installing sealing strip, and described sealing strip includes
Weatherstrip body and the rubber layer of environmental sealing bar body, weatherstrip body adopts metal manufacture.
This utility model is arranged further: described valve body inner piece is in u shape, and described valve body inner piece is arranged on left valve barrel
Edge with the valve opening of right valve barrel.
This utility model is arranged further: described seal groove is arranged on valve body inner piece, and described sealing strip passes through sealing
Groove is matched with valve body inner piece.
This utility model is arranged further: described valve body inner piece and rubber layer are all made using polyurethane.
This utility model beneficial effect: described left valve barrel and right valve barrel are all inlaid with the valve body liner matching with flashboard
, so that flashboard moves up and down in valve body, flashboard is inconsistent with valve body inner piece for part, and flashboard produces metal friction with valve body, carries
High service life, because valve body inner piece has elastic deformation characteristic, during flashboard compression valve body inner piece, valve body inner piece can be sent out
Raw elastic deformation, even closer laminating flashboard, so can effectively improve the sealing of slide valve, valve body inner piece is sent out using process
It is just permissible that raw abrasion only needs to be individually replaced valve body inner piece, is easy to keep in repair, reduces maintenance cost；
Described sealing strip includes weatherstrip body and the rubber layer of environmental sealing bar body, and weatherstrip body adopts metal
Manufacture so that this sealing strip retains metal sealing strip high-intensity performance, rubber layer also avoids sealing strip to produce gold with valve body simultaneously
Belong to friction, improve service life.

Specific embodiment
1 to Fig. 4 wear-resisting knife gate valve a kind of to this utility model is described in further details referring to the drawings.
A kind of wear-resisting knife gate valve, including valve body 1 and flashboard 2, is provided with, in described valve body 1, the sealing strip matching with flashboard 2
3, described valve body 1 includes left valve barrel 11 and right valve barrel 12, and described left valve barrel 11 and right valve barrel 12 are all inlaid with and are matched with flashboard 2
Valve body inner piece 4, valve body inner piece using have resilient nonmetallic materials make, elasticity nonmetallic materials can be poly-
Urethane or other elastomeric materials, described valve body inner piece 4 is inconsistent with flashboard 2 so that flashboard 2 moves up and down in valve body 1,
Flashboard 2 is inconsistent with valve body inner piece 4, and flashboard 2 produces metal friction with valve body 1, improves service life, due to valve body inner piece
4 have elastic deformation characteristic, and during flashboard 2 compression valve body inner piece 4, valve body inner piece 4 can occur elastic deformation, even closer patch
Combined floodgate plate 2, so can effectively improve the sealing of flashboard 2 valve, and valve body inner piece 4 occurs abrasion to only need to individually more using process
Change wedge just permissible, be easy to keep in repair, reduce maintenance cost；；
The mating surface of described left valve barrel 11 and right valve barrel 12 is equipped with the seal groove 13 for installing sealing strip 3, described close
Strip of paper used for sealing 3 includes weatherstrip body 31 and the rubber layer 32 of environmental sealing bar body 31, and weatherstrip body 31 adopts metal manufacture,
This sealing strip 3 is made to retain metal sealing strip 3 high-intensity performance, rubber layer 32 also avoids sealing strip 3 and valve body 1 to produce gold simultaneously
Belong to friction, improve service life.
Described valve body inner piece 4 is in u shape, and described valve body inner piece 4 is arranged on left valve barrel 11 and the valve opening of right valve barrel 12
