The present invention relates to a fire hydrant for the fire hydrant equipment and a method of using the fire hydrant, and in particular, the hydrant equipment that can prevent the generation of the shooter in the connection pipe naturally by the continuous flow of water in the connection pipe from the water pipe to the fire hydrant It relates to a water spray prevention device and a method of using the same.

In general, a large amount of water is required to extinguish a fire in a city, and a fire hydrant or a sprinkler is provided on the inside and outside of a building to supply a large amount of water. Fire hydrants are connected directly to the underground pipes, so that large amounts of water can be supplied in case of emergency. When the fire hydrant is installed outside of the building, the fire hydrant is installed at a distance that is easily accessible.

1 schematically illustrates a conventional fire hydrant 30 buried underground in a roadside of a city. As shown in FIG. 1, the conventional fire hydrant 30 is connected to the water supply pipe 10 through a branch pipe 20, and a valve 40 is embedded at the bottom of the fire hydrant 30. The valve 40 may be opened and closed by the switch 32 exposed at the top of the fire hydrant (30). Therefore, in case of emergency, by coupling a fire hose (not shown) to the outlet 34 of the fire hydrant 30, and opening the valve 40, a large amount of water flowing through the water pipe 10 is branch pipe 20 ) And through the fire hydrant 30, and then immediately spout out through the outlet 34 and the hose coupled to the fire hydrant (30). On the other hand, the said valve 40 is normally closed by the said switch 32, and is preserve | saved in that state.

Since the conventional fire hydrant equipment is composed of the water supply pipe 10, the branch pipe 20, the valve 40 and the fire hydrant 30 in this way, there is no problem in case of emergency, but usually has some problems.

First, in the conventional fire hydrant equipment, the water inside the branch pipe 20 is stagnant in the usual time, thereby generating water (死水). This is because, as confirmed above, the valve 40 is normally closed, so that water contained in the pipe of the branch pipe 20 is present in the state, and when a certain time elapses, Because it is naturally decayed and can only be converted to rotting water.

Second, the conventional fire hydrant equipment is usually required for continuous and continuous management and maintenance work. This is because, as described above, since the shooter is inevitably generated inside the branch pipe 20 during normal times, in order to prevent this, it is necessary to replace the water inside the regular cycle before changing to the shooter. In a conventional fire hydrant installation, for this operation, the valve 40 of the fire hydrant 30 should be opened at least every six months to discharge the water in the branch pipe 20 to the outside. In reality, however, it is not difficult to carry out these tasks continuously.

Third, the conventional fire hydrant equipment has a disadvantage that can not exclude the possibility of contaminating the water of tap water. In the conventional fire hydrant equipment, when there is a shooter in the branch pipe 20, the inside of the branch pipe 20 until the shooter is safely discharged to the outside. This is because there is a possibility that flow into the water pipe 10 is inevitably in communication with the branch pipe (20). This is a serious problem because it pollutes the water supply that ordinary citizens use as drinking water.

As such, the conventional fire hydrant equipment has a number of problems, which are primarily caused by the shooter water generated in the branch pipe 20, which is from the water pipe 10 to the fire hydrant 30. The longer the distance, the greater the amount of shooters in proportion to it, and the more serious the side effects.

On the other hand, the conventional technology for preventing the shooting water generated in such a fire hydrant facility is disclosed in the Republic of Korea Utility Model No. 2000-5488 "Waterworks Sprinkler Prevention System" and Republic of Korea Utility Model Registration 201207 "Waterworks Sprinkler Prevention System "Is introduced. The two "water supply shooter prevention device" is configured to send a part of the water flowing in the water pipe 10 to the branch pipe 20 by a locking plate, in which case the branch pipe 20 Since it does not have a structure that can circulate all the water inside, there is a disadvantage that can not prevent the origin of the still water (still water) due to the stagnant water.

In this way, the conventional conventional fire hydrant equipment usually retains the water accumulated in the branch pipe as it is or flows only a part thereof, and also retains the rest in a stagnant state, so that water is generated in the branch pipe. Is not solved at all, and the prior art as an improved product thereof does not fundamentally prevent the occurrence of shooters in the branch pipe.

Accordingly, it is an object of the present invention to provide a fire fighting shooter prevention device for newly generating a water pipe in the branch pipe by changing the structure of a branch pipe of a conventional fire hydrant.

Another object of the present invention is to provide a fire hydrant for preventing fire, which does not generate water in the branch pipe at all, while using a conventional fire hydrant as it is.

It is also an object of the present invention to provide a method for using a fire hydrant preventing device for preventing fire from occurring in the branch pipe by newly changing the structure of a branch pipe of a conventional fire hydrant.

The present invention relates to a shooter preventing device used in fire hydrant equipment and a method of using the same.

Fire hydrant for the fire hydrant facility according to the present invention is a water supply pipe for sending water from the water supply source, the branch pipe is connected to the water pipe and sends the water of the water pipe, and the branch pipe is connected to the fire extinguisher hose in the fire In the fire hydrant equipment consisting of a fire hydrant, the branch pipe is formed of a U-shaped tube consisting of an inlet for drawing water from the water pipe and an outlet for sending water from the water pipe back to the water pipe, The type pipe includes a first valve at its inlet and a second valve at its outlet, and the water pipe includes a third valve in the middle of a coupling position between the inlet and the outlet.

In addition, the method of using the fire hydrant prevention device for fire hydrant according to the present invention is a water supply pipe for sending water from the water supply source, and the U-shaped as a whole is connected to the inlet and the outlet to the water pipe and the first valve and the outlet portion in the inlet portion A method of using a fire hydrant device comprising a U-type pipe having a second valve and a hydrant coupled to the U-type pipe, wherein the first valve and the second valve are normally opened, and the third valve is partially opened. Alternatively, by closing all the water, the water flowing through the water pipe continues to flow inside the U-shaped pipe, thereby preventing the fire hydrant from being fired.

In the present invention, in the case of emergency, in the case of emergency, the fire hydrant can be opened by using the switch of the fire hydrant as in the usual case, and there is no need to perform separate operation. In this case, it is because the water in the water pipe directly pumps up to the fire hydrant. If the water pressure is weak, when the second valve and the third valve are closed, all the water flowing through the water pipe flows into the fire hydrant, so that a much higher flow rate is secured more quickly than the conventional fire hydrant. There are also advantages to doing this.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in more detail. However, the accompanying drawings are only intended to describe the technical spirit of the present invention in more detail, and the technical spirit of the present invention is not limited thereto.
