Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a gate valve with a slag discharge structure. Background Art

[0002] The gate valve is an opening and closing part, the movement direction of the gate 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. Usually the sealing surface will be welded with metal materials to increase wear resistance, such as cladding 1Cr13, STL6, stainless steel, etc.

[0003] The existing Chinese patent CN111895173B disclosed a gate valve on October 19, 2021, comprising: a valve body having an inlet flow channel and an outlet flow channel; a gate plate slidably arranged in the valve body, the gate plate being able to block the inlet flow channel and the outlet flow channel; a valve stem rotatably connected to the upper end of the gate plate and threadedly connected to the valve body, and the gate plate can be driven to move in a vertical direction by rotating the valve stem, thereby controlling the on and off of the gate valve, and a balancing valve sleeve is fixedly connected to the valve stem, and by making the force of the medium acting on the balancing valve sleeve and the gate plate in a balanced state, the medium under high pressure will not produce a large resistance to the opening and closing of the gate plate, so that the gate plate is easier to open and close.

[0004] However, when the above device is closed, the water source is blocked by the gate plate. Impurities in the water source are blocked by the gate plate, so the impurities will adhere to the surface of the gate plate. When cleaning, there is no good slag discharge structure, so the slag will remain inside, and the whole device needs to be disassembled to clean the impurities. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a gate valve with a slag discharge structure is proposed. When a person opens the slag discharge gate plate cover, the water valve gate plate is lifted due to the retraction of the gate plate lifting cylinder. Impurities attached to the surface of the water valve gate plate can be cleaned through the gate plate cleaning plate, and the cleaned impurities are discharged through the holes after the slag discharge gate plate cover is disassembled. After the impurities are discharged, the slag discharge gate plate cover is re-sealed, so that the outside can be used directly after water is passed, and there is no need to disassemble the whole for cleaning, which makes cleaning more efficient and convenient.
