Abstract

PROBLEM TO BE SOLVED: To connect fire hoses having different bores by applying the constitution that a plurality of ferrules are arranged on the the peripheral side of a dead-end cylinder fitted to the drain port of a fire hydrant open/close valve, so as to be continuous to the drain hole and directed in the same direction as well as to correspond to fire hoses having different diameters. SOLUTION: A fire hydrant open/close valve 1 is installed with a feed port 1a screwed to the end of a steel pipe 2 laid in a fire hydrant box, and has a valve disc 1d fitted via a valve spindle 1c continuous to a turning handle 1b, a valve seat 1e and a drain port 1f. A discharge port device B is installed via a flange ring 3 screwed to the internal thread 1g of the drain port 1f. In this case, the discharge port device B has a dead-end cylinder 4 with one end closed and the other end open, and openings 4f and 4g are formed on the peripheral side 4e of the dead-end cylinder 4. In a normal state, the openings 4f and 4g are closed with caps 5a and 5a. At the time of use, the caps 5a and 5a are removed, and then connectors mounted on a fire hose end are coupled or screwed to the openings 4f and 4g.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water outlet device which is a fire squad dedicated to a fire brigade provided in a fire hydrant box or a water outlet storage box.

[0002]

2. Description of the Related Art It is customary to have a water outlet equipped with a base for connecting a fire hose diameter designation of 65A, and there appears to be a water outlet equipped with a base capable of connecting both fire hose diameter designations of 65A and 50A. is there.

[0003]

A water outlet is used to connect a fire hose dedicated to a fire brigade as well as to a device built in a fire hydrant box for the purpose of extinguishing fires at an early stage and a middle stage. Or a fire hose connection port provided at the drain of a fire hydrant on-off valve that communicates via a steel pipe from a water outlet installed near it, and is required to be installed on each of the second and higher floors of a building with seven or more floors. Generally, it is provided in the fire hydrant box in addition to the water outlet storage box dedicated to the water outlet. However, as described above, the water outlet in the prior art is usually provided with a base for connection of a name 65A, which is a name according to the diameter of the fire hose, so that the name is 50A or 40A for a fog gun. When connecting hoses, they must be connected via different diameter metal fittings, which hinders emergency fire fighting activities.

[0004] For this reason, it seems that a water outlet equipped with a base to which fire hoses of names 65A and 50A can be connected is used, but if one base is used to handle two kinds of diameters. It is considered that the inner diameter of the base is 50A, that is, based on the small diameter, and according to this, 65A (large diameter)
There is a problem with water discharge and water pressure when connecting a fire hose.

[0005] In view of the above, an object of the present invention is to make a designation 65A,
An object of the present invention is to provide a water outlet device provided with a plurality of bases to which fire hoses such as 50A and 40A can be connected.

[0006]

In order to achieve the above object, a fire-extinguishing water outlet device is provided with a bag cylinder capable of being angularly fixed in a circumferential direction connected to a drain port of a fire hydrant on-off valve. A plurality of connection bases, which communicate with the drain port and the bag cylinder, are oriented in the same direction, and correspond to different diameters of fire hoses of different diameters, are arranged on the side surface.

[0007]

According to the present invention, since a plurality of connecting bases for each of the fire hoses of different diameters are provided in the bag cylinder communicating with the fire hydrant opening / closing valve, the fire hose diameter brought by the fire brigade can be responded to immediately. Since the cap is oriented in the same direction and the bladder is provided so as to be angularly displaceable and fixed in the circumferential direction with respect to the drain port of the hydrant on-off valve, the pipe end position in the fire-extinguishing water steel pipe in the hydrant box Irrespective of the above, the connection base can always be arranged in the front, so that the connection of the fire hose is simple, which contributes to quick fire fighting.

FIG. 1 is a view showing the arrangement of the water outlet device, FIG. 2 is a front view of the water outlet device, and FIG. FIG. 4 is a cross-sectional view taken along line X-X 'of FIG. 2, FIG. 5 is a cross-sectional view showing a state in which a screw-type base is mounted, and FIG. 6 is a state in which a fire hose is connected via a fitting. FIG. 7 shows a fire hose diameter designation 50A.
FIG. 8 is a longitudinal sectional view of a bag cylinder provided with three types of openings, which will be described below with reference to the drawings.

In the drawing, reference numeral 1 denotes a fire hydrant on-off valve, and the fire hydrant on-off valve 1 is a pipe of a steel pipe 2 for supplying fire-extinguishing water piped into a fire hydrant box A from a water inlet installed at a front entrance of a building or in the vicinity thereof. The hydrant opening / closing valve 1 is provided with a valve body 1d provided through a valve rod 1c connected to a rotating handle 1b, a valve seat 1e, and a drain port 1f.
A water outlet device B is disposed via a flange wheel 3 screwed to the female screw 1g of the drain port 1f.

The water outlet device B comprises a bag 4 having a sheath shape with one end closed and the other end opened. The flange 4b is provided at the open end 4a of the bag 4 and the flange 4b is provided. The fire hydrant on-off valve 1 and the hollow portion 4c of the bag cylinder 4 are communicated with each other by being fixed to the flange portion 3a of the wheel 3 with screws 3b,
Flange 3a of flange wheel 3 and flange 4 of bag cylinder 4
b, connecting holes 3c and 4d through which the screws 3b are inserted.
Are arranged at least at four equal concentric positions on the concentric circle, or a 90 ° arc-shaped long hole is arranged only at one flange portion 3a at a relative position on the concentric circle, and at the other flange 4b. Are two connecting holes 4 corresponding to each of the arc-shaped long holes.
d, for example, the bag cylinder 4 is provided so as to be displaceable at an angle of at least 90 ° on the circumference with respect to the drain port 1f of the fire hydrant on-off valve 1 so as to be fixed. Openings 4f and 4g corresponding to the hose diameter designations 65A and 40A are opened to communicate with the hollow portion 4c, and the female screws 4f 'and 4g' engraved in the openings 4f and 4g have designations 65A and 40A respectively. The connecting plug base 5 or the screw base 6 (FIG. 5) corresponding to each of the fire hoses H is screwed and fixed, and closed with the cap 5a or 6a in a normal state. , 6a are removed, and a fitting 7 attached to the end of the fire hose H is fitted or screwed into and connected.
