Outdoor antifreezing and damp-proof type fire hydrant used for low-temperature environment ship

Abstract

The invention discloses an outdoor antifreezing and damp-proof type fire hydrant used for a low-temperature environment ship. A water inlet port of a fire valve is connected to a first end of a fire water pipe, the fire water pipe and the fire valve are arranged in a cabin wall, and a second end of the fire water pipe communicates with water source; a fire hydrant joint is arranged on the outer side of the cabin wall, and the fire hydrant joint is connected with a water outlet port of the fire valve in a direct communicating mode; an auxiliary pipeline is arranged in the cabin wall arranged outside the fire water pipe, a first end of the auxiliary pipeline communicates with the first end of the fire water pipe, and a second end of the auxiliary pipeline communicates with the second end ofthe fire water pipe; a first water pump is connected to the auxiliary pipeline; the first water pump is controlled to be started and stopped by a controller according to the temperature in the cabin wall; and the fire water pipe is located at the upper end of the fire valve, the fire hydrant joint is located at the lower end of the fire valve, and the outlet end of the fire hydrant joint is located at the lowest position of a water outlet pipeline arranged between the fire valve and the fire hydrant joint. According to the outdoor antifreezing and damp-proof type fire hydrant used for the low-temperature environment ship, normal using of the fire hydrant in cold areas like a polar region is guaranteed, and the situation that water cannot flow from the fire hydrant due to the fact that thefire hydrant is frozen is avoided.

Description

technical field [0001] The invention relates to a fire hydrant used in an open-air space in a wet fire-fighting system of a sailing ship in a low-temperature environment, and belongs to the technical field of shipbuilding, in particular to an open-air anti-freezing wet fire hydrant for a ship in a low-temperature environment. Background technique [0002] Ships using wet fire fighting in cold regions such as polar regions, because the water in the fire pipes is always exposed to the cold environment, it is prone to freezing, and the fire protection system cannot meet the requirements of wet fire fighting systems that can supply water. The traditional wet fire hydrants of ships sailing in low temperature environment need to arrange electric heat tracing or steam heat tracing, which consumes a lot of energy, and special protection boxes need to be installed; or fire hydrants need to be arranged in indoor positive temperature places, but fire water is required Protected outdoor...

[0002] Ships using wet fire fighting in cold regions such as polar regions, because the water in the fire pipes is always exposed to the cold environment, it is easy to freeze, causing the fire fighting system to fail to meet the requirements of wet fire fighting systems that can supply water

The traditional wet fire hydrants of ships sailing in low temperature environment need to arrange electric heat tracing or steam heat tracing, which consumes a lot of energy, and special protection boxes need to be installed; or fire hydrants need to be arranged in indoor positive temperature places, but fire water Protected outdoor spaces are inconvenient to use
