Abstract

The utility model discloses a tightly sealed knife-edge valve with a good use effect. The knife-edge valve comprises a valve body and a gate, wherein the gate is arranged in the valve body; a sealing ring is fixedly arranged on a valve body and on one side of the gate; three or more gate wedge blocks are fixedly arranged above the gate; three or more valve body wedge blocks are fixedly arranged at the upper part of the valve body; and the positions of the gate wedge blocks correspond to the positions of the valve body wedge blocks. The knife-edge valve has the advantages that when the knife-edge valve is in use, and the gate is closed downwards, the gate wedge blocks and the valve body wedge blocks push against one another, and the gate is forced to be in tight contact with the sealing ring on one side, so that the use effect is improved.

Description

Knife-edge valve

Technical field

The utility model relates to a kind of valve mechanical field, relates in particular to a kind of 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, and 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 the utility model provides a kind of knife-edge valve tight, that using effect is good that seals.

For realizing above-mentioned purpose, the technological scheme that the utility model adopted is:

A kind of knife-edge valve; Comprising: valve body, flashboard; Flashboard is installed in the valve body, is installed with seal ring on the valve body of flashboard one side, and its characteristics are: described flashboard upper fixed is designed with flashboard wedge degree piece; Described valve body top Fixed Design has valve body wedge degree piece, and flashboard wedge degree piece is corresponding with valve body wedge degree piece position.

According to above-mentioned knife-edge valve, its characteristics are: described flashboard wedge degree piece and three of corresponding installations of difference of valve body wedge degree piece or polylith.

The utility model has the advantages that: the utility model in use, when closing flashboard downwards, flashboard wedge degree piece and valve body wedge degree piece push mutually, force flashboard to contact with the seal ring of a side is tight, have increased using effect.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

A kind of knife-edge valve is like Fig. 1, shown in 2; Comprising: valve body 1, flashboard 2; Flashboard 2 is installed in the valve body 1, is installed with seal ring 3 on the valve body 1 of flashboard 2 one sides, and flashboard 2 upper fixed are designed with flashboard wedge degree piece 4; Valve body 1 top Fixed Design has valve body wedge degree piece 5, and flashboard wedge degree piece 4 is corresponding with valve body wedge degree piece 5 positions.

In the present embodiment, flashboard wedge degree piece 4 and valve body wedge degree piece 5 three of corresponding installations of difference or polyliths.

The utility model beneficial effect is: the wedge degree of flashboard wedge degree piece in the utility model and valve body wedge degree piece is inequality, and flashboard cuts out downwards, and flashboard closely is connected with seal ring on the side valve body, leaks in eliminating.

Embodiment recited above describes the preferred implementation of the utility model; Be not that design and protection domain to the utility model limits; Under the prerequisite that does not break away from the utility model design concept; Common engineers and technicians make the technological scheme of the utility model in related domain various modification and improvement all should fall into the protection domain of the utility model.
