Abstract
The utility model discloses a kind of flexible ceramic gate valve, including valve body, flashboard, compression skewback and drive system, described flashboard includes valve plate, ceramic-seal ring, spring and valve plate seat, described valve plate and described valve plate seat are Split type structure, described ceramic seal circle is fixed on described valve plate, arranges by described spring between described valve plate and described valve plate seat.In this utility model, flashboard is to include valve plate, valve plate seat, ceramic-seal ring and the flexible flashboard of spring composition, this flashboard ensure that under any working condition, the sealing property of valve and start-stop performance, solve under high temperature, high pressure conditions, the rigid extruding of flashboard, valve seal, causes ceramic seal circle fragmentation or the stuck problem of thermal expansion；And the sealing surface uniform force of ceramic seal circle, compensate for ceramic gate valve pressured tight skewback pressure, causes the defect of sealing surface unbalance stress.
Description
Technical field
This utility model relates to gate valve field, particularly relates to a kind of flexible ceramic gate valve.
Background technology
Gate valve refers to that valve plate is driven by valve rod, lifts or the valve of side-to-side movement, can with electronic, pneumatic, surge and
Manually etc. mode drives gate valve plate, opens or block the passage of fluid.At present, in ceramic gate valve, flashboard is single disc, valve
Seal the pressured tight skewback of thrust to realize, but when using compression skewback structure, skewback is uneven to valve plate thrust, easily causes
Valve plate deforms, and makes ceramic-seal ring fragmentation, affects the sealing property of valve；And compress skewback and valve seal is rigid connecing
Touch, when seal pressure is excessive, easily cause the damage of sealing surface；And under high temperature and high pressure condition, easily cause valve card
Extremely.
Utility model content
The purpose of this utility model is to provide a kind of flexible ceramic gate valve, it is possible to solve skewback to valve plate thrust inequality
Technical problem.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of flexible ceramic gate valve, including valve body, flashboard, compression skewback and drive system, described flashboard includes valve plate, pottery
Porcelain sealing ring, spring and valve plate seat, described valve plate and described valve plate seat are Split type structure, and described ceramic seal circle is fixed on described
On valve plate, arrange by described spring between described valve plate and described valve plate seat.
Preferably, the material of described valve plate and described valve plate seat is wear-resisting, corrosion resistant metal or special engineered pottery material
Material.
The beneficial effects of the utility model are:
This utility model provides a kind of flexible ceramic gate valve, and flashboard is for including valve plate, valve plate seat, ceramic-seal ring and bullet
The flexible flashboard of spring composition, this flashboard ensure that under any working condition, the sealing property of valve and start-stop performance, solves
Under high temperature, high pressure conditions, the rigid extruding of flashboard, valve seal, causes ceramic seal circle fragmentation or stuck the asking of thermal expansion
Topic；And the sealing surface uniform force of ceramic seal circle, compensate for ceramic gate valve pressured tight skewback pressure, causes sealing surface stress
Uneven defect.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation of this utility model flexible ceramic gate valve.
In figure: 1, valve body；2, skewback is compressed；3, valve plate seat；4, spring；5, valve plate；6, ceramic seal circle.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
As it is shown in figure 1, a kind of flexible ceramic gate valve that this utility model provides, including valve body 1, flashboard, compression skewback 2 and
Drive system, flashboard includes valve plate 5, ceramic-seal ring, spring 4 and valve plate seat 3, and valve plate 5 and valve plate seat 3 are Split type structure, pottery
Porcelain sealing ring 6 is fixed on described valve plate 5, arranges by spring 4 between valve plate 5 and valve plate seat 3.
In technique scheme, valve plate 5, valve plate seat 3, ceramic-seal ring and spring 4 form flashboard for flexible flashboard, this knot
The flashboard of structure ensure that under any working condition, the sealing property of valve and start-stop performance, solves at high temperature, high pressure shape
Under state, flashboard, valve body 1 seal rigid extruding, cause ceramic seal circle 6 fragmentation or the stuck problem of thermal expansion；Ceramic seal circle 6
Sealing surface uniform force, compensate for the pressured tight skewback 2 of ceramic gate valve and press, cause the defect of sealing surface unbalance stress.
In the present embodiment, the material of valve plate 5 and valve plate seat 3 is wear-resisting, corrosion resistant metal or special engineered pottery
Material.
It should be noted that spring 4 can be the spring 4 of cylindrical spring 4 or other forms.
Disclosed above being only specific implementation of the patent example, but this patent is not limited to this, general for this area
For logical technical staff, on the premise of without departing from this utility model principle, the deformation made should be regarded as belonging to this utility model
Protection domain.
