    The case 10 has a rectangular shape and a fire hose 70 is installed therein. Support frames 12a and 12b are respectively installed at the lower end of the case 10, and each of the support frames 12a and 12b is embedded in the basement by a predetermined depth. At this time, the second connecting pipe 26 is inserted into the support frame 12a, and inside the support frame 12b is provided with a handle 18 to open and close the hydrant valve 16 to be described later. One valve rod 20 is inserted. In addition, the insulating material 28 is filled in each of the support frames 12a and 12b to prevent freezing during winter.

    On the other hand, the hydrant valve 16 which is opened and closed by the valve rod 20 is installed in the lower portion of the support frame 12b buried underground. Water supply pipe 14 is installed at the lower end of the hydrant valve 16, the first connection pipe 22 is installed on one side.

    And the T-shaped tube 24 is installed at the end of the first connecting tube 22 and the second connecting tube 26 described above, the water introduced into the first connecting tube 22 through the water supply pipe 14. It can be smoothly supplied to the second connecting pipe (26).

On the other hand, the lower end of the T-shaped tube 24 is formed with a protruding tube 25 is formed with a threaded outer peripheral surface, the drainage trap 30 shown in Figs. 2 and 3 is coupled to the protruding tube 25.

    The configuration of the drain trap 30 is as follows. First, the distal end of the connecting cap 34 is screwed to the lower end of the protruding tube 25. At this time, a conventional O-ring 56 is inserted between the protruding pipe 25 and the connection cap 34 to prevent leakage.

    And the cap bolt 32 is screwed to the lower end of the connection cap 34. At this time, the aforementioned 0-ring 56 is inserted between the cap bolt 32 and the connecting cap 34.

That is, the coupling pipe 36 is installed on the outer circumferential surface of the discharge trap so that soil, sand, gravel, etc. do not penetrate into the cap bolt 32 when buried underground so that a failure does not occur.

    Hereinafter, the operating state of the hydrant configured as described above will be described below. First, when a fire occurs, the user rotates the handle 18 installed on one side of the case 10 to open the hydrant valve 16, so that the water in the water supply pipe 14 embedded in the basement has a water pressure of 2 kg / cm 2 or more. Through the hydrant valve 16 through the first connecting pipe 22 is introduced into the T-type tube (24). At this time, the drain trap 30 installed at the lower end of the T-type tube 24 is automatically closed by the incoming water pressure so that water is introduced into the second connection tube 26 installed on the upper portion of the T-type tube 24. do.

    That is, more specifically, the water introduced into the T-shaped tube 24 is introduced into the drain trap 30 through the protruding tube 25 as shown in FIG. At this time, the guide pin 40 inserted into the guide groove 38 of the cap bolt 32 is lowered by the hydraulic pressure, and accordingly the protruding jaw of the disk 42 formed on the guide pin 40. As the 44 contacts the contact surface 48 of the guide groove 38, the guide groove 40 is blocked, so that water does not fall into the cap bolts 32 and the outlets 52 and 58 of the coupling pipe 36. It is to be introduced into the second connecting pipe 26 installed on the upper portion of the T-shaped tube (24). Since water is discharged through the fire hose 70 coupled to the second connecting pipe 26, it is possible to extinguish the fire initially.

    On the other hand, when the fire extinguishing is completed to rotate the handle 18 in the reverse direction, the hydrant valve 16 is closed to completely block the incoming water. At this time, the water that is not discharged remains in the first and second connection pipes 22 and 26, and the remaining water is discharged to the outside through the drain trap 30.

    That is, in detail, as shown in FIG. 3, the guide pin 40, which has been in contact with the contact surface 48 of the guide groove 38 by the water pressure, is rapidly dropped in water as the water is blocked. By the elasticity, the guide pin 40 is raised upward, so that the guide groove 38 is opened to allow residual water to flow therein. Thereafter, the water remaining in the first and second connection pipes 22 and 26 through the plurality of outlets 52 formed in the cap bolt 32 and the outlet 58 of the coupling pipe 36 is freely dropped to drain traps. It will be discharged to the outside.

That is, the water remaining in the first and second connection pipes 22 and 26 due to the above action is quickly and safely, that is, discharged without being disturbed from soil, sand, gravel, etc., so that no residual water remains at all in winter. It is possible to prevent the freezing of the tube that occurs frequently in the.

And the present invention is the hydrant valve 16 and the valve rod 20 is coupled by the socket 110. A female thread is formed inside the socket, and a male thread is formed at each of the front end of the valve rod and the front end of the hydrant valve. Therefore, it is possible to select and use several valve rods of different lengths as needed when the terrain where the fire hydrant is installed is inclined or the rock is underground. In other words, any one of a plurality of valve rods having different lengths of the hydrant valve may be selected and coupled to the hydrant valve. Likewise, the T-type tube 24 and the second connection tube 26 may be coupled by the socket 110. In this case, any one of a plurality of second connecting pipes having different lengths may be combined. After connecting the fire hydrant valve and the valve rod to the socket, connect a plurality of fixing screws to the fixing screw holes formed on the outer periphery of the socket to make the connection more secure. In the embodiment of the present invention, the fastening using four fixing screws.

The expansion joint pipe 120 is to form a pleated portion in the middle of the first connecting tube 22, and the protective cover is separately covered on the pleated portion. In general, when installing a fire hydrant, when the ground is inclined or there is a rock in the basement, it is difficult to horizontally connect the second hydrant pipe connecting the hydrant valve and the T-shaped pipe horizontally, and thus, the upper valve rod or the second connection. The tube is not vertically fixed but tilted. However, if the expansion pipe of the present invention is installed in the middle of the first connecting pipe, even though the hydrant valve and the T-shaped pipe is different in height, the expansion pipe is bent and the valve rod or the second connecting pipe is fixed vertically. will be.

In addition, the present invention is to install a first malodor backflow trap 130 in the first connecting pipe (22). The first malodor counterflow trap 130 is a function of removing the odor flowing back from the drain trap by placing a bent portion of the water in the middle of the first connecting pipe 22 is a straight pipe. Odor is blocked by the water's sealing action not to the water pipe.

And, the present invention is to install a waste water backflow prevention trap 150 at the lower end of the coupling pipe of the drain trap. The wastewater backflow prevention trap 150 is to install a drain plug 151 coupled to the hinge in the outlet 58 formed in the chamber, the drain plug 151 can open and close the hinge to the central axis, but the spring on the hinge It has a hinge structure for pipes with a stopper and it is opened to the outside by the weight of water remaining in the first and second connecting pipes 22 and 26, and closed again by the force of the spring. In the stopper is configured to no longer close in. Since the hinge structure uses a hinge installed in a general building door, detailed description thereof will be omitted. Therefore, the waste water outside the drain trap cannot enter the hydrant of the present invention. In other words, only water remaining in the first and second connection pipes 22 and 26 is discharged to the outside, and external waste water is not allowed to enter the inside. And the present invention is to install a second malodorous backflow prevention trap 140 in the lower portion of the wastewater backflow prevention trap (150). The second malodor counterflow trap 140 is composed of a convex top plate and a concave bottom plate that can contain water so as to block odors, so that water is automatically formed between the top plate and the bottom plate, so that the odor is directed toward the water supply pipe. To prevent backflow. Bongsu blocks the smell is the same as the first malodor counterflow trap.
