The fire-resistant gate valve uses a gate plate as its opening and closing part (in the structure of a gate valve, the opening and closing part is called the gate plate, and the matching seat is called the gate seat). The gate plate moves vertically up and down the centerline of the gate seat passage. When the gate plate is fully raised, the pipe is fully open, and the medium can flow smoothly; when the gate plate is lowered and fully contacts the gate seat, the pipe is cut off, and the flow of the medium is completely stopped, thus effectively controlling the medium in the pipe. In practical use, it is necessary to avoid slightly opening the gate plate, because the high-speed flowing medium will strongly erode the sealing surface, accelerating the damage of the sealing surface, affecting the service life and sealing performance of the valve.

The threaded soft seal gate valve is a substitute for traditional threaded iron gate valves and copper ball valves. It has the following characteristics: 1. Traditional gate valves have recesses at the bottom of the inner cavity, which easily cause debris accumulation and prevent them from closing tightly, causing water leakage. The threaded soft seal gate valve has a flat bottom without any recesses, allowing for unimpeded fluid flow and preventing debris accumulation. 2. The gate valve uses a fully enclosed food-grade rubber gate plate, which is complete, smooth, beautiful, meets drinking water hygiene requirements, has reliable sealing performance, and is leak-free. 3. The valve body is coated with a sanitary-grade resin, enhancing its corrosion resistance, making it environmentally friendly, beautiful, and long-lasting, without secondary pollution of the medium. 4. The outer surface is sprayed with a non-toxic epoxy resin paint, which is beautiful and corrosion-resistant.

Protective gate valves, also known as civil air defense protective valves, are made of copper core and copper gate valve materials. They include visible stem copper core copper stem protective valves and hidden stem copper core copper stem protective valves. These valves use a gate (the closing member) driven by a valve stem to move up and down along the sealing surface of the valve seat, connecting or cutting off the fluid channel. Gate valves have low flow resistance and require little effort to open and close, making them widely used for opening and closing civil air defense pipelines. When a gate valve is partially open, vortices are generated behind the gate, which can cause erosion and vibration of the gate and damage the sealing surface of the valve seat, making repairs difficult. Therefore, protective gate valves use copper core sealing to prevent corrosion and maintain smooth opening and closing.
