[0002] The gate valve is a gate plate of an opening and closing part. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate plate. Usually, the sealing surface is welded with metal materials to increase wear resistance. The gate plate has a rigid gate plate and an elastic gate plate. According to the difference in the gate plate, the gate valve is divided into a rigid gate valve and an elastic gate valve; the existing gate valve has poor sealing performance, and leakage is likely to occur at the connection, which is not only dangerous, but also causes varying degrees of waste;

[0003] After searching, it is found that the authorization announcement number is: CN217271990U, which is a gate valve with good sealing effect. Although the gate valve has the advantage of improving the sealing of the gate valve body, the connection of the gate valve is not provided with a sealing structure. When the arc-shaped baffle becomes loose, the gate valve is very likely to leak, affecting subsequent use.

[0004] Therefore, a gate valve with good sealing effect is proposed to solve the above problems. Utility Model Content
