Detailed Description

In order to make the structure and function of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solution 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 arranged on.

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 sundries in the pipe are washed to the fire pool.

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.

It should be noted that the utility model discloses the drawing is the schematic diagram, and the condition is complicated in the factory, all connects a plurality of fire hydrants on each fire branch pipe, and fire water branch pipe valve is normally open type, and the return water main valve is normally closed type, does not influence the use of fire hydrant, and after fire water manages the operation a period, opens the circulation that the return water main valve carried out fire water, prevents that debris deposit in the pipeline.

The utility model relates to a waterproof ring-shaped is laid in the factory, and after fire water operation a period, the valve on each branch road is closed to the accessible, manages the circulation one by one with fire water, with intraductal remaining iron rust, impurity such as silt rush to fire pool 1, rethread blowoff valve 12 row to sewage pipe network after the deposit of 1 bottom in fire pool, reach to eliminating impurities such as silt in the fire water management, prevent the deposit purpose of corroding that the pipeline long-term operation caused.

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