Fire pump connectors are connecting devices used by fire trucks and mobile pumps to deliver fire water or other liquid extinguishing agents to the fire water supply system inside buildings. Connectors generally consist of a main body, fire interface, safety valve, water flow check valve, and water flow shutoff device, etc. The structural design ensures that the remaining water between the fire interface and the water flow check valve can be drained after use. According to the installation type, they can be divided into ground type, underground type, wall type, and multi-purpose type.

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.
