Detailed Description

In order to make the structure and function of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention.

Referring to the attached drawing 1, the corrosion-inhibition annular fire-fighting pipe comprises a fire-fighting water pool 1 and a fire-fighting water pump 2 connected with the fire-fighting water pool, a fire-fighting water pump outlet valve 3 is arranged on an outlet pipeline 13 of the fire-fighting water pump, the outlet pipeline of the fire-fighting water pump is connected with five fire-fighting branch pipes 14, each fire-fighting branch pipe 14 is connected with one water return branch pipe 15, each water return branch pipe 15 is provided with a fire-fighting water branch pipe valve, the five water return branch pipes 15 are connected to a water return main pipe 16 and communicated to the fire-fighting water pool 1 through a water return main pipe 16, a water return main valve is.

Based on above-mentioned technical scheme, when need not fire water to circulate, it can to close the return water main valve. When a certain fire branch pipe needs to be washed, the corresponding fire branch pipe is opened only, the corresponding fire water branch pipe valve opens the corresponding water return branch pipe, and the water return main valve is opened, so that the fire water circulation of the fire pool → the fire branch pipe → the water return main pipe → the fire pool can be completed, meanwhile, the opened fire branch pipe is washed, and the process of flushing sundries in the pipe to the fire pool is realized.

Furthermore, the number of the water return main pipes is two, and each water return main pipe is provided with a water return main valve. In consideration of water flow, when all fire-fighting water branch pipe valves are opened and all fire-fighting branch pipes are washed, one water return main pipe cannot meet the backflow of all fire-fighting water, so that the two water return main pipes can be connected in parallel, and the two water return main pipes can be used for one by one, so that when one water return main pipe is damaged, the water return main pipe can be replaced in time, and the paralysis of the whole fire-fighting water circulation system is avoided.

Further, the fire branch pipes 14 provide emergency water for fire fighting for each device in the plant area, and each fire branch pipe is connected with a fire hydrant 11. Under the ordinary state, each return water main valve is closed, and fire pump 2 keeps pressure for each fire branch pipe 14, guarantees that fire hydrant 11 can normal use.

The working process is as follows: the factory fire water comes from the fire pool 1, pressurizes through the fire pump 2, and send to fire water ground and each fire branch pipe through fire pump outlet valve 3. Under the ordinary state, each return water main valve is closed, and fire pump 2 is the pressurize of each fire branch pipe 14, guarantees that fire hydrant 11 can normal use, and the rivers are in no flow state in each fire branch pipe this moment basically. After the fire-fighting water pipe runs for a period of time, the first water-returning main valve 9 or the second water-returning main valve 10 is opened, and then the first fire-fighting water branch pipe valve 4, the second fire-fighting water branch pipe valve 5, the third fire-fighting water branch pipe valve 6, the fourth fire-fighting water branch pipe valve 7 and the fifth fire-fighting water branch pipe valve 8 are opened in sequence; make fire water at the pipeline internal loop erode, finally reach the fire control and manage interior debris and wash clean, prevent that the pipe wall from adhering to the purpose that the deposit corrodes the pipeline. For example, a first fire branch pipe needs to be cleaned, the first fire water branch pipe valve 4 corresponding to the first fire branch pipe is opened, the first water return main valve 9 is opened, and the second fire water branch pipe valve 5, the third fire water branch pipe valve 6, the fourth fire water branch pipe valve 7, the fifth fire water branch pipe valve 8 and the second water return main valve 10 are closed; the sediments such as rust or silt in the first fire branch pipe circulate to the fire pool 1 through the first fire branch pipe valve 4 and the first main return valve 9 along with the fire water, and simultaneously, impurities in the pipe are flushed to the fire pool 1, and after the impurities are precipitated in the pool, the impurities are discharged to a sewage system through the drain valve 12.

The attached drawing is a schematic diagram, the conditions in a plant area are complex, each fire branch pipe is connected with a plurality of fire hydrants, a fire water branch pipe valve is normally open, a water return main valve is normally closed, the use of the fire hydrants is not affected, and after a fire water pipe runs for a period of time, the water return main valve is opened to circulate fire water so as to prevent sundries in the pipe from depositing.

The invention is designed to be annularly paved in a plant area in a waterproof way, after fire fighting water runs for a period of time, the fire fighting water pipe can be circulated one by closing the valves on each branch, impurities such as rust, silt and the like remained in the fire fighting water pipe are flushed to the fire fighting water pool 1, and the impurities such as the silt and the like in the fire fighting water pipe are discharged to a sewage pipe network through the drain valve 12 after the impurities are deposited at the bottom of the fire fighting water pool 1, so that the purposes of eliminating the impurities such as the silt and the like in the fire fighting water pipe and preventing the.

The above list is only the preferred embodiment of the present invention. It is obvious that the invention is not limited to the above embodiments, but that many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the invention.
