Description

Fire-fighting water supply system for building

Technical Field

The application relates to the field of fire-fighting water source supply, in particular to a building fire-fighting water supply system.

Background

When a fire disaster occurs in the building, a fire water supply system in the building needs to supply water to a fire system in the building, and a common fire system in the building is a water mist spray head, a temperature sensor and a smoke sensor which are matched with each other, so that the fire water supply system in the building is required to continuously provide a large amount of water and high pressure for a period of time.

A fire water supply system for a building is disclosed as CN208809360U and comprises a transfer water tank, a water supply device and a fire pipeline. The transfer water tank is arranged on a refuge layer of the building. The water feeder is arranged on the first floor of the building and is used for being connected with a water outlet of the fire engine and conveying fire water in the fire engine outwards. The water inlet end of the fire-fighting pipeline is connected with the water feeder, and the water outlet end of the fire-fighting pipeline is communicated with the water transferring tank.

In view of the above-mentioned related technologies, the inventor believes that the water feeder may feed more impurities into the transfer water tank, so that when a water source in the transfer water tank is pumped to a water mist nozzle arranged in a building, the water mist nozzle may be blocked to reduce the amount of water sprayed, and there is a defect that the water feeding system may cause the water mist nozzle not to work normally.

SUMMERY OF THE UTILITY MODEL

In order to reduce the possibility that the water supply system causes the water mist spray head to be blocked and not to work properly, the application provides a fire fighting water supply system for a building.

The application provides a building fire control water supply system adopts following technical scheme:

the utility model provides a building fire control water supply system, is including locating in the building and save the fire water tank at fire control water source, locate the building and to send into the bottom water supply pipe of fire-fighting water in the fire water tank, communicate in the fire water tank and with the water pump in the fire water tank send to the case outlet pipe in the inside water smoke shower nozzle of building, the inside in-box baffle that separates into two parts with fire water tank inside that is equipped with of fire water tank, the baffle upper surface is located above the liquid level in the fire water tank in the case, and the water inlet one end of bottom water supply pipe delivery port one end and case outlet pipe is located the both sides of in-box baffle respectively, and the several mesh has been seted up in the case baffle runs through, is equipped with in the mesh and carries out filterable filter to the water in the fire water tank.

Through adopting above-mentioned technical scheme, the bottom flow pipe is gone into the water pump and is saved to the fire water tank in, and the water source of incasement baffle towards bottom flow pipe one side flows to incasement baffle towards case outlet pipe one side after the filtration of filter screen for be difficult for having more suspension impurity in entering into the water source to case outlet pipe, make the difficult condition that appears blockking up of water smoke shower nozzle by case outlet pipe water supply.

Optionally, the coaxial threaded connection of mesh inner wall has the filter body pipe, and the filter body is located in the filter body pipe, and the filter body pipe is close to the coaxial fixedly connected with pipe ring piece of one end of bottom layer flow pipe, and pipe ring piece butt is in incasement baffle.
