Abstract
The invention discloses a butt clamp bifacial sealing knife-edge valve which has the advantages of tight sealing and good using effect. The butt clamp bifacial sealing knife-edge valve comprises a valve body and a flashboard, wherein the flashboard is arranged in the valve body, the left and right sides of the flashboard are respectively fixedly provided with a flashboard wedge degree ring, and the thickness of the bottom of each flashboard wedge degree ring is less than that of the upper part of each flashboard wedge degree ring; the left and right sides of the interior of the valve body are respectively fixedly provided with a valve body wedge degree ring, the positions of the flashboard wedge degree rings and the valve body wedge degree rings are corresponding, and the thickness of the bottom of each valve body wedge degree ring is greater than that of the upper part of each valve body wedge degree ring; the position of the inner side of the valve body, corresponding to the flashboard wedge rings, is designed with a wedge degree, and the thickness of the bottom of the wedge degree is greater than that of the upper part of the wedge degree; and a valve body soft sealing ring is arranged at the position of the two sides or one side in the valve body, corresponding to the flashboard wedge rings. The butt clamp bifacial sealing knife-edge valve provided by the invention has the advantages that when the butt clamp bifacial sealing knife-edge valve is used and a flashboard is downwards closed, the flashboard wedge degree rings and the valve body wedge rings or the valve body are mutually pushed; and the flashboard and the valve body are forced to closely contact, so that the using effect is increased.
Description
Technical field
The present invention relates to a kind of valve mechanical field, relate in particular to a kind of to folder 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 invention is to provide a kind of seal tight, using effect is good to folder dual face seals knife-edge valve.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of to folder dual face seals knife-edge valve, comprising: valve body, flashboard, flashboard are installed in the valve body, and its characteristics are: arranged on left and right sides fixedly is designed with respectively flashboard wedge degree annulus on the described flashboard.
To folder dual face seals knife-edge valve, its characteristics are according to above-mentioned: the thickness of described flashboard wedge degree annulus bottom is less than the thickness on top.
To folder dual face seals knife-edge valve, its characteristics are: arranged on left and right sides fixedly is designed with valve body wedge degree annulus in the described valve body, and flashboard wedge degree annulus is corresponding with valve body wedge degree annulus position according to above-mentioned.
To folder dual face seals knife-edge valve, its characteristics are according to above-mentioned: the thickness of described valve body wedge degree annulus bottom is greater than the thickness on top.
To folder dual face seals knife-edge valve, its characteristics are according to above-mentioned: the inboard Position Design corresponding with flashboard wedge degree annulus of described valve body has the wedge degree, and described wedge degree is that bottom thickness is greater than the thick section in top.
To folder dual face seals knife-edge valve, its characteristics are: both sides or the side position corresponding with flashboard wedge degree annulus in the described valve body are installed with valve body soft seal ring according to above-mentioned.
Advantage of the present invention is: the present invention in use, when closing flashboard downwards, flashboard wedge degree annulus and valve body wedge degree annulus or valve body push mutually, force flashboard tightly to contact with valve body, have increased using effect.

Embodiment
The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
Embodiment 1
A kind of to folder 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 arranged on left and right sides fixedly is designed with respectively flashboard wedge degree annulus 3 on the flashboard 2.
In the present embodiment, the thickness of flashboard wedge degree annulus bottom is less than the thickness on top; In the present embodiment, valve body 1 interior arranged on left and right sides fixedly is designed with valve body wedge degree annulus 4, and flashboard wedge degree annulus 3 is corresponding with valve body wedge degree annulus 4 positions; The thickness of valve body wedge degree annulus 4 bottoms is greater than the thickness on top; Both sides in the valve body 1 or a side and flashboard wedge degree annulus 3 corresponding positions are installed with valve body soft seal ring.
A kind of to folder 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 arranged on left and right sides fixedly is designed with respectively flashboard wedge degree annulus 3 on the flashboard 2.
In the present embodiment, the thickness of flashboard wedge degree annulus 3 bottoms is less than the thickness on top; In the present embodiment, the inboard Position Design corresponding with flashboard wedge degree annulus 3 of valve body 1 has the wedge degree, and described wedge degree is that bottom thickness is greater than the thick section in top; Both sides in the valve body 1 or a side and flashboard wedge degree annulus 3 corresponding positions are installed with valve body soft seal ring.
The invention has the beneficial effects as follows: the flashboard wedge degree annulus among the present invention is not identical with the direction of the wedge degree of valve body wedge degree annulus, 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 invention; be not that design of the present invention and protection domain are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technological scheme of the present invention in related domain various modification and improvement all should fall into protection scope of the present invention.
