The fire-resistant butterfly valve mainly consists of core components such as the valve body, butterfly plate, valve stem, and rubber (NBR) sealing ring. The butterfly plate is installed inside the valve body, and its opening, closing, or regulating function is achieved through the rotation of the valve stem. When the valve stem rotates the butterfly plate, the flow area between the butterfly plate and the valve body can be changed, thereby achieving precise control of the medium flow. The rubber (NBR) sealing ring is tightly embedded between the valve body and the butterfly plate to ensure excellent sealing performance when the valve is closed and effectively prevent medium leakage.

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 water flow indicator is an auxiliary alarm device in an automatic sprinkler fire extinguishing system. It is generally installed on the water supply main or branch pipes in each zone of the system. It converts the signal of water flow into an electrical signal to monitor and alarm the system. The water flow indicator consists of a main body, a micro switch, a paddle, and a flange (or threaded) three-way valve. When a fire occurs in a certain area of the system and the sprinkler sprays water, the signal of water flow in the pipe network is converted into an electrical signal output, transmitted to the module or control center to display the fire location, and realize area alarm. When the sprinkler stops spraying water, the paddle automatically resets to the servo state, and the alarm disappears.

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.
