Embodiment 1

[0018] Embodiment 1: The elastic occlusal mechanism under the left valve plate can be called the left elastic occlusal mechanism, the upper elastic filling body is called the left upper elastic filling body, the lower cavity part is called the left lower cavity part, There is a first slider and a second slider in the cavity of the first layer. Similarly, the elastic occlusal mechanism under the right valve plate can be called the right elastic occlusal mechanism, and the upper elastic filling body is called the upper right elastic filling body. , the lower cavity part is called the right lower cavity part, and the third slider and the fourth slider are arranged in the right lower cavity part.

[0019] A preferred example of the present invention is that both ends of the lower cavity part are further provided with a guide slope 9 located below the elastic connector, and the highest end of the guide slope is fixedly connected to the end wall of the lower cavity part. The role of...

Abstract

The invention discloses an anti-displacement soft sealing gate valve which comprises a valve rod (1), a valve cover (2), a valve body (3) and a valve plate. The valve plate comprises a left valve plate (4) and a right valve plate (5) which are connected with the valve rod, a certain gap is reserved between the left valve plate and the right valve plate, and elastic meshing mechanisms are arrangedon valve body channels below the left valve plate and a right valve plate; each elastic meshing mechanism comprises an opening groove capable of accommodating the left valve plate / the right valve plate, wherein the opening groove is divided into an upper layer elastic filling body (6) and a lower layer cavity part, two end walls of the lower layer cavity part are respectively connected with sliding blocks (8) through elastic connecting pieces (7), and the sliding blocks are located on the two sides of the left valve plate / the right valve plate. The anti-displacement soft sealing gate valve has the beneficial effects that when the left valve plate and the right valve plate move downwards, the left valve plate and the right valve plate are in contact with the elastic meshing mechanisms, theupper elastic filling bodies are deformed in a V shape, the two sides of the left valve plate and the right valve plate are meshed, reliable clamping force is provided, and lateral displacement of the valve plate is prevented.

Description

technical field [0001] The invention relates to a valve, in particular to a soft-sealed gate valve and a use method thereof. Background technique [0002] The opening and closing part of the gate valve is the valve plate, and the movement direction of the valve plate is perpendicular to the flow direction of the medium. The gate valve is generally used for full opening and full closing, and cannot be adjusted and throttled. The valve plate has two sealing surfaces. The most commonly used mode is that the two sealing surfaces of the valve plate are wedge-shaped. The wedge angle varies with the valve parameters. The wedge angle of the soft gate is about 8 degrees, and that of the hard gate is about 2.5 degrees. The valve plate of the wedge gate valve can be made as a whole, and the sealing surface is inlaid with copper or different types of steel, which is called a rigid valve plate. This type of gate valve is called a metal hard-sealed gate valve, hereinafter referred to as a...
