Problems solved by technology

[0002] At present, the sealing device of the valve body of the domestic wafer type knife valve is installed on one side of the valve body, and the flow direction of the liquid flows from one end of the valve to the other end. When the valve gate is closed, due to the sealing device of the knife valve It is only installed on one side of the valve body, the seal is not tight, and the liquid will leak from the sealing device, which seriously affects the use effect of the knife valve

Embodiment 1

[0018] A wafer double-sided sealing knife valve, such as figure 1 , 2 As shown, it includes: a valve body 1, a gate 2, the gate 2 is installed in the valve body 1, and the left and right sides of the gate 2 are respectively fixed with gate wedge rings 3.

[0019] In this embodiment, the thickness of the bottom of the gate wedge ring is smaller than the thickness of the upper part; in this embodiment, valve body wedge rings 4 are fixedly designed on the left and right sides of the valve body 1, and the gate wedge The ring 3 corresponds to the position of the valve body wedge ring 4; the thickness of the bottom of the valve body wedge ring 4 is greater than the thickness of the upper part; the two sides or one side of the valve body 1 correspond to the gate wedge ring 3 The position of the valve is fixed with a soft sealing ring of the valve body.

Embodiment 2

[0021] A wafer double-sided sealing knife valve, such as figure 1 , 2 As shown, it includes: a valve body 1, a gate 2, the gate 2 is installed in the valve body 1, and the left and right sides of the gate 2 are respectively fixed with gate wedge rings 3.

[0022] In this embodiment, the thickness of the bottom of the wedge wedge ring 3 is smaller than the thickness of the upper part; in this embodiment, a wedge is designed at the position corresponding to the wedge wedge ring 3 inside the valve body 1, the said The wedge is that the thickness of the bottom is greater than that of the upper part; two sides or one side of the valve body 1 corresponding to the wedge wedge ring 3 are fixedly installed with soft sealing rings of the valve body.

[0023] The beneficial effects of the present invention are: the direction of the wedge degree of the disc wedge ring in the present invention is different from that of the valve body wedge disc, and when the gate plate is closed downward,...

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 [0001] The invention relates to the field of valve machinery, in particular to a wafer double-sided sealing knife valve. Background technique [0002] At present, the sealing device of the valve body of the domestic wafer type knife valve is installed on one side of the valve body, and the flow direction of the liquid flows from one end of the valve to the other end. When the valve gate is closed, due to the sealing device of the knife valve It is only installed on one side of the valve body, and the seal is not tight, and the liquid will leak from the sealing device, which seriously affects the use effect of the knife valve. Contents of the invention [0003] The object of the present invention is to provide a double-sided sealed knife valve with tight sealing and good use effect. [0004] To achieve the above object, the technical solution adopted in the present invention is: [0005] A double-sided sealed knife-shaped valve for clamping, which includes...
