Description

An electric wear-resistant slurry gate valve

technical field

The utility model relates to the technical field of valves, in particular to an electric wear-resistant ore slurry gate valve.

Background technique

The gate valve is an opening and closing gate, 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 and throttled, the gate valve is sealed by the contact between the valve seat and the gate, usually sealed The surface will be surfacing with metal materials to increase wear resistance, such as surfacing 1Cr13, STL6, stainless steel, etc. The gate has rigid gate and elastic gate. According to the difference of the gate, the gate valve is divided into rigid gate valve and elastic gate valve.

At present, the existing electric wear-resistant gate valves generally use the gate to realize fluid on-off, but after the gate is used for a long time, the gate itself will wear to a certain extent, resulting in fluid leakage from the gate when the valve is closed , the lack of alarm function will cause the staff to not find out in time, which will cause certain economic losses. When the staff finds the leakage in time, they need to close the main valve, and it takes a certain time to close the main valve, which will lead to excessive fluid leakage. Many, for this reason, we propose an electric wear-resistant slurry gate valve.
