[0002] A typical gate valve mainly consists of a valve body, a valve cover, a gate, and a valve stem. The valve cover is fixed to the valve body, and the valve stem passes through the valve cover. The outer end of the valve stem connects to the handwheel, and the inner end connects to the gate. Rotating the valve stem moves the gate up and down, thus opening and closing the gate valve. Due to the influence of the external environment (such as dust, rainwater, and acidic gases), the valve stem often corrodes or rusts, preventing the gate valve from opening and closing smoothly, which may adversely affect production or safety.
