Features

Large flow water supply: Capable of providing a substantial amount of firefighting water within a short time, typically with a discharge rate greater than that of a standard ground hydrant, suitable for extinguishing large-scale fires.

- Quick on/off operation: For instance, the SSFT series high-flow ground fire hydrants, with a quick on/off feature, can be fully opened or closed by turning the handle just 4/5 rotations.

- Features pressure regulation: Internally equipped with a pressure-reducing device, it can be segmented to open under the action of fire water pressure, achieving pressure reduction and ensuring the safe and stable supply of fire-fighting water.

- Anti-freeze and collision-resistant design: Features a spring-sealed drain outlet in the structure, which can automatically close the valve upon being broken, immediately stopping the water flow. It also automatically drains excess water inside, preventing the equipment from freezing damage.

Structure

-栓体: Consists of the upper and lower sections, containing a reverse-graduated sealing component with decreasing diameters from top to bottom within the cavity, which can seal the top of the cavity under hydraulic pressure.

- Lever assembly: Extending from the upper part of the bolt body to the lower part, rotating the lever assembly allows the reverse sequential sealing assembly to open from bottom to top in a step-by-step manner.

- Interface: Features a large diameter of 150mm or 100mm for connecting the fire truck's pump suction pipe; also includes two smaller diameter of 65mm interfaces for attaching fire hoses.

- Additional Components: Includes items such as switch valves, drainage systems, collision protection structures, etc.
