Abstract

The utility model discloses a kind of novel sealing structure gate valve, it comprises valve body, flashboard, valve seals and ram seal circle, it is characterized in that, the inner circle of described ram seal circle has carried out hollow process and flashboard is non-contact seal structure.The utility model can significantly improve the sealability under high pressure conditions, can guarantee the normal operation of high pressure conditions lower pipeline.

Description

Novel sealing structure gate valve
Technical field:
The utility model belongs to valve field, especially brake gate door, is specifically related to a kind of novel sealing structure gate valve.
Background technique:
The flashboard of existing gate valve and the sealing of valve body 0 ' 1 normally valve body are provided with a valve body sealing device 0 ' 2, flashboard 0 ' 4 is provided with bronze ram seal circle 0 ' 3 device, especially the bronze ram seal circle 0 ' 3 of flashboard 0 ' 4 normally solid structure, and belong to direct contact type with flashboard 0 ' 4 to seal, do not absorb the ability of valve body resiliently deformable, as Fig. 3.This structure flashboard bronze be sealed in engineering pressure higher when, valve body is under high pressure effect, and meeting generation resiliently deformable more or less, has so just had a strong impact on the sealability of valve itself, cause pipeline to seal, great harm is caused safely to pipeline.
Summary of the invention:
The purpose of this utility model is to provide a kind of valve body deformation when can absorb high pressure and the novel sealing structure gate valve of good sealing effect.
In order to realize the utility model, the technological scheme that the utility model is taked is as follows:
A kind of novel sealing structure gate valve, it comprises valve body, flashboard, valve seals and ram seal circle, it is characterized in that, the inner circle of described ram seal circle has carried out hollow process and flashboard is non-contact seal structure.
The utility model has carried out hollow process due to the inner circle of ram seal circle, and such ram seal circle can absorb fully to the resiliently deformable of valve body, fully ensure that the sealability of valve.When loine pressure is very large, utilizes hollow gap effectively can absorb the distortion of valve body, thus ensure that the sealing under valve high pressure conditions.
Accompanying drawing illustrates:
Fig. 1 is the structural representation after the utility model is installed;
Fig. 2 is the utility model flashboard and ram seal circle A place enlarged view;
Fig. 3 be A place adopt existing flashboard and ram seal circle time enlarged view;
In Fig. 1,2, valve body 1, valve seals 2, ram seal 3, flashboard 4.
In Fig. 3, valve body 0 ' 1, valve seals 0 ' 2, ram seal 0 ' 3, flashboard 0 ' 4.
Embodiment:
Embodiment 1:
As shown in Figure 1, 2, a kind of novel sealing structure gate valve, it comprises valve body 1, valve seals 2, flashboard 4, ram seal circle 3, and the inner circle of wherein said ram seal circle 3 has carried out hollow process and flashboard 4 is non-contact seal structure.
The utility model has carried out hollow process due to the inner circle of ram seal circle 3, and such ram seal circle 3 can absorb fully to the resiliently deformable of valve body 1, fully ensure that the sealability of valve.When loine pressure is very large, utilizes hollow gap effectively can absorb the distortion of valve body 1, thus ensure that the sealing under valve high pressure conditions.
First valve seals 2 is mechanically embedded on valve body 1 when the utility model is installed, ram seal circle 3 is mechanically embedded on flashboard 4 simultaneously.
The utility model can significantly improve the sealability under high pressure conditions, can guarantee the normal operation of high pressure conditions lower pipeline.
