Description

Technical Field

[0001] The utility model relates to the field of water conservancy facilities, and more specifically, to a small water conservancy gate valve. Background Art

[0002] A gate valve primarily consists of a valve body, gate, stem, seat, and actuator. The gate moves up and down within the valve body, controlling or blocking the flow of fluid by varying the flow area between the gate and seat. Gate valves are commonly used in water supply and drainage systems and small canals to control water flow and pressure, facilitating agricultural irrigation.

[0003] The gate of the gate valve moves in the limit groove of the plate frame. There is a certain gap between the gate and the limit groove. Therefore, the sealing of the gate valve is not enough and water will seep in. It is necessary to improve the structure of the gate valve and improve its sealing. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a small hydraulic gate valve with stronger sealing performance.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions.

[0007] Furthermore, a plate moving foot is welded on one side of the water retaining gate plate, and the plate moving foot and the foot sinking groove correspond one to one.

[0008] Furthermore, a sealing gasket is provided on one side of the plate limiting groove, and the sealing gasket and the plate limiting groove are fixed by adhesive bonding.

[0009] Furthermore, the lifting screw and the rotating wheel are screwed together by threads.

[0010] Furthermore, a transverse plate is welded inside the gate frame, and the transverse plate divides the internal space of the gate frame into a water-passing window and a plate retracting window.

[0011] Compared with the prior art, the advantages of the present invention are:

[0012] The water blocking gate plate of the present application is movably installed below the C-shaped hanging buckle, and can move forward and backward, thus canceling the structure of the water blocking gate plate fixed by screws. BRIEF DESCRIPTION OF DRAWINGS
