Description

Technical Field

[0001] The invention relates to the technical field of mud valves, in particular to a mud valve capable of preventing sludge deposition and blockage. Background Art

[0002] Knife gate valve is also called knife gate valve, knife gate valve, slurry valve, mud valve. Its opening and closing parts are gates. The movement direction of the gate is perpendicular to the direction of the fluid. The medium is cut off by the blade-shaped gate that can cut fiber materials. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form a wedge. The wedge angle varies with the valve parameters, usually 5°. The gate of the wedge knife gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This gate is called an elastic gate. When the knife gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface. This is self-sealing. Most gate valves use forced sealing, that is, when the valve is closed, the gate is forced to press against the valve seat by external force to ensure the sealing of the sealing surface.

[0003] During the use of the mud valve, the mud is cut by the blade gate. The cut mud will stay on both sides of the gate. After cutting for a period of time, the mud will dry and adhere. The mud on both sides of the gate will agglomerate and cause blockage, thereby affecting the transportation of the mud and reducing the efficiency of the mud transportation. Summary of the invention
