Description

Technical Field

[0001] The utility model relates to a dock fire water operation system, in particular to a fire water circulation and loading system, belonging to the technical field of fire pipeline design. Background Art

[0002] The wharf is currently 600m 3 The terminal has a fire water tank, an electric fire water pump, and a backup diesel fire water pump. To ensure the normal backup of the fire pump, the terminal fire diesel pump is regularly started and debugged as required. Each time the fire diesel pump is debugged, the operator needs to go down into the fire well and open the corresponding valve (valve specification DN350) in the narrow underground well space to achieve the purpose of fire water circulation. This operation is very inconvenient and there are safety risks in working in a confined space.

[0003] The original fire truck water supply pipeline pumped water into the fire truck through the fire truck's onboard pump. The fire truck water supply line extended to the middle of the fire water pool. Therefore, when water was added to the middle of the pool, the pump would be emptied and the water in the lower part of the pool could not be pumped into the fire truck.

[0004] The original fire water circulation line is located in a fire well, where the space is small, the pipeline is thick, and the valve opening and closing are extremely difficult. Utility Model Content

[0010] Furthermore, the fire diesel pump circulation line is drawn from the fire truck pumping line and connected to the position between the first control valve and the one-way valve of the underground circulation line;

[0011] Furthermore, the underground circulation line has a diameter of DN350, and the pipeline is relatively thick;

[0012] Furthermore, the fire-fighting diesel pump circulation line is set at an above-ground position at a height of 1.5 meters from the ground;
