The utility model discloses a new structure improves the disk seat of current inflation gate valve, has set up the sealed structure of lip formula sealing washer, has avoided using in the past rubber O type circle structure can take place to react and the unable problem with the medium when certain special operating mode, and the sealed structure of this lip formula sealing washer has very high sealing performance simultaneously, can satisfy the needs of various special operating modes, the utility model has the advantages of simple and reasonable structure, the installation is used sealed effectual, and the cost of manufacture is low, and the practicality is strong.
Description
Technical Field
The utility model relates to an inflation gate valve specifically relates to an inflation gate valve lip type seals disk seat structure.
Background
The sealing between the valve seat and the valve body of the commonly used expansion gate valve usually adopts a rubber O-shaped ring sealing structure, but rubber can react with media under certain special working conditions, so that the expansion gate valve cannot be used. And this kind of operating mode has higher requirements to the sealing performance of valve, for this reason, we propose an inflation gate valve lip type seal valve seat structure.
Disclosure of Invention
The utility model aims to solve the technical problem that an inflation gate valve lip formula seals disk seat structure is provided, has solved the sealed structure of current rubber O type circle, and rubber O type circle can react with the medium when certain special operating mode, and can not use to this kind of operating mode requires higher problem to the sealing performance of valve.
In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides an inflation gate valve lip type seals disk seat structure, includes flashboard, disk seat, valve body, sealing washer and sealed the pad, the left and right sides of flashboard symmetry respectively is equipped with the disk seat, two the disk seat is fixed mounting respectively in the valve body, a plurality of sealing washers of fixedly connected with between disk seat and the valve body, the disk seat is located one side fixedly connected with of flashboard and seals up.
On the basis of the scheme, the flashboard is in sliding sealing fit with the sealing gasket.
On the basis of the scheme, the sealing ring is a lip type sealing ring.
On the basis of the scheme, the sizes of the central holes of the two valve seats and the inner hole of the valve body are the same and are on the same axis.
Compared with the prior art, the utility model beneficial effect who has is: the utility model provides an inflation gate valve lip formula seal disk seat structure adopts new structure, improves the disk seat of current inflation gate valve, has set up the sealed structure of lip formula sealing washer, has avoided using in the past rubber O type circle structure can react and the unable problem of using with the medium when certain special operating mode, and the sealed structure of this lip formula sealing washer has very high sealing performance simultaneously, can satisfy the needs of various special operating mode, the utility model has the advantages of simple and reasonable structure, the installation is used sealed effectual, and the cost of manufacture is low, and the practicality is strong.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to fig. 1 to 2, it can be known that the lip type sealing valve seat structure of the expansion gate valve comprises a gate plate 1, valve seats 2, a valve body 3, sealing rings 4 and sealing gaskets 5, wherein the valve seats 2 are symmetrically arranged on the left side and the right side of the gate plate 1 respectively, the two valve seats 2 are convenient to seal with the gate plate 1, the two valve seats 2 are fixedly arranged in the valve body 3 respectively, the sealing rings 4 are fixedly connected between the valve seats 2 and the valve body 3, the sealing rings 4 are convenient to seal between the valve seats 2 and the valve body 3, the sealing gaskets 5 are fixedly connected to one side, located on the gate plate 1, of the valve seats 2, and the sealing gaskets 5 are convenient to seal between.
The flashboard 1 is in sliding sealing fit with the sealing gasket 5, so that the liquid in the valve body 3 is blocked conveniently; the sealing ring 4 is a lip type sealing ring, has good sealing effect, can not react with other media, and is suitable for different special working conditions; the central holes of the two valve seats 2 are the same as the inner hole of the valve body 3 in size and are on the same axis, so that the liquid in the valve body 3 can conveniently circulate.
The utility model discloses a principle and advantage: the utility model provides an inflation gate valve lip formula seal disk seat structure, is to improving the 2 sealed modes of disk seat of current inflation gate valve, changes rubber O type circle seal structure in the past into the seal structure of lip formula sealing washer, when some special operating mode uses, can not take place the sealing washer and the sealed problem of medium emergence reaction influence, and the seal structure sealing performance of this lip formula sealing washer is good simultaneously, can satisfy the requirement of various special operating mode to valve seal nature, the utility model has the advantages of simple and reasonable structure, the leakproofness is good, and the cost of manufacture is low, is fit for using widely.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
