Abstract
The utility model discloses a double-side seal knife-shaped valve which is capable of tight sealing and has good using effect. The knife-shaped valve comprises a valve body and a flashboard, wherein the flashboard is mounted in the valve body, the left board and the right board of the flash board are designed to be wedged, and the thickness of the bottom of the flashboard is less than that of the upper part of the flashboard. Valve body wedges are designed at positions inside the valve body corresponding to the wedges of the flashboard, and the thickness of the bottom of the valve body wedges is greater than the thickness of the upper part of the valve body wedges. Valve body soft sealing rings are fixedly mounted at positions corresponding to the wedges of the flashboard on two sides or one side inside the valve body. The knife-shaped valve has the advantages that when the valve is in use, and when the flashboard is closed downward, the wedges of the flashboard and the wedges of the valve body or the valve body push and press against each other and force the flashboard and the valve body to form a close contact, so that the using effect is improved.
Description
Technical field
The utility model relates to a kind of valve mechanical field, relates in particular to a kind of dual face seals knife-edge valve.
Background technique
At present, the seal arrangement of the valve body of domestic wafer type knife-edge valve is installed in a side of valve body, the flow direction of liquid flows to the other end from an end of valve, when the flashboard of valve cuts out, because the seal arrangement of knife-edge valve only is installed in a side of valve body, poorly sealed, liquid can leak in seal arrangement, has a strong impact on the using effect of knife-edge valve.
Summary of the invention
The purpose of this utility model provides a kind of dual face seals knife-edge valve tight, that using effect is good that seals.
For achieving the above object, the technological scheme that adopts of the utility model is:
A kind of dual face seals knife-edge valve, comprising: valve body, flashboard, flashboard are installed in the valve body, and its characteristics are: the left and right plate face of described flashboard is designed to the wedge degree, and the thickness of the bottom of flashboard is less than the thickness on flashboard top.
According to above-mentioned dual face seals knife-edge valve, its characteristics are: the inboard Position Design corresponding with flashboard wedge degree of described valve body has valve body wedge degree, and described valve body wedge degree is that bottom thickness is greater than the thick section in top.
According to above-mentioned dual face seals knife-edge valve, its characteristics are: both sides or the side position corresponding with flashboard wedge degree in the described valve body are installed with valve body soft seal ring.
The utility model has the advantages that: the utility model in use, when closing flashboard downwards, flashboard wedge degree and valve body wedge degree or valve body push mutually, force flashboard tightly to contact with valve body, have increased using effect.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of dual face seals knife-edge valve, as shown in Figure 1, 2, comprising: valve body 1, flashboard 2, flashboard 2 are installed in the valve body 1, and the left and right plate face of flashboard 2 is designed to the wedge degree, and the thickness of the bottom of flashboard 2 is less than the thickness on flashboard 2 tops.In the present embodiment, the valve body 1 inboard Position Design corresponding with flashboard wedge degree has valve body wedge degree 3, and described valve body wedge degree 3 is that bottom thickness is greater than the thick section in top; In the present embodiment, both sides or the side position corresponding with flashboard wedge degree in the valve body 1 is installed with valve body soft seal ring.
The beneficial effects of the utility model are: the flashboard wedge degree in the utility model is not identical with the direction of valve body wedge degree, and when flashboard cut out downwards, flashboard was more and more tightr with contacting of valve body, leaks in eliminating.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in related domain various modification and improvement all should fall into protection domain of the present utility model.
