Multi-layer electroplated tungsten alloy corrosion-resistant wear-resistant internal and external plated sleeve

The utility model discloses a multi-layer electroplated tungsten alloy corrosion-resistant and wear-resistant internal and external plating sleeve. The device comprises a first multi-layer wear-resisting sleeve, a fixing pipeline and a second multi-layer wear-resisting sleeve, a first fixing block is fixedly connected to the left side of the first multi-layer wear-resisting sleeve, and a first fixing frame is fixedly connected to the surface of the side, close to the first multi-layer wear-resisting sleeve, of the first fixing block. According to the utility model, the movable rotating rod andthe limiting block are arranged; moving a rotary rod by rotation, the limiting block can move in the first fixing block; therefore, the surfaces of the first fixing block and the second fixing blockcan abut against each other through the limiting block. The sealing performance of the joint of the first fixing block and the second fixing block is effectively enhanced; and through the arrangementof the fixing clamping plat
