DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance valve in a fire hydrant device installed in a building such as a building or a tunnel.

[0002]

2. Description of the Related Art A fire hydrant device installed in a building such as a building or a tunnel, for example, generally has a fire extinguishing hose having a base end connected to a fire extinguishing agent supply source and a nozzle at a tip end. It is used to extinguish a fire generated by a fire extinguishing agent discharged from a nozzle via a hose. In a fire hydrant device provided with such a fire extinguisher hose, the fire extinguisher hose is always housed in a housing, and is used by being pulled out from the housing when a fire occurs.

In the fire hydrant device as described above, when performing a discharge check to determine whether or not the fire hydrant device maintains a predetermined function and performance, it is possible to perform a discharge check without allowing water to flow through a fire hose. In some cases, a primary side of a fire-extinguishing hose in a housing is provided with a valve for maintenance. This maintenance valve has a connection port for the emission check device,
The secondary side flow path of the valve is switched from the flow path on the fire extinguishing hose side to the side to which the discharge inspection device is connected.
Therefore, at the time of the release check, the release check device is connected to the discharge check device connection port of the maintenance valve, and the secondary flow path of the maintenance valve is switched to the discharge check device side. The discharge inspection of the fire hydrant device can be performed without passing water through the fire extinguishing hose by passing water through the fire extinguishing test using a pressure gauge or the like.

In general, a fire hydrant device has an opening on the front side of a housing so that a fire extinguishing hose can be pulled out from the front side of the housing or vice versa. Although the fire hydrant device is provided with the maintenance valve, the forward sloping door for opening and closing the opening is also provided. The door is opened, and the discharge inspection device is connected to the maintenance valve through the opening.

[Problems to be solved by the invention]

[0006] The maintenance valve in the conventional fire hydrant device is provided such that its connection port faces directly in front of the housing. For this reason, the maintenance valve in the conventional fire hydrant device has the following problems when performing the discharge inspection work.

When connecting the discharge inspection device to the connection port of the maintenance valve, the worker performs the connection work in an unreasonable posture with the arm extended from the front side of the housing through the front tilting door. Work is difficult. When connecting the discharge inspection device to the connection port of the maintenance valve, instead of connecting the worker from the front side of the housing through the front leaning door, even when connecting from the side of the front leaning door Since the connection port of the maintenance valve faces the front direction of the housing, connection work cannot be performed on the connection port from the front direction. Therefore, there is no difference that the worker will perform the connection work in an impossible posture,
The task remains challenging. When the discharge check device is connected to the maintenance valve and water is passed from the maintenance valve to the discharge check device, the hose portion of the discharge check device tries to extend straight due to water pressure, but the hose portion of the discharge check device tries to expand. In the direction, that is, in front of the connection port of the maintenance valve, various equipments (operation levers, operation nameplates, etc.) on the front tilting door are located, and these equipments are such that the hose portion of the discharge inspection device extends straight. Will be in the way. For this reason, when performing a discharge check by passing water through the discharge check device,
Since the work must be performed so that the various equipments on the front leaning door do not interfere with the discharge inspection device that is in a water-permeable state, the work is difficult.

In view of the above circumstances, an object of the present invention is to provide a maintenance valve for a fire hydrant device capable of facilitating connection work of a discharge inspection device.

Another object of the present invention is to provide a maintenance valve for a fire hydrant device, which makes it possible to easily perform a discharge check operation by a discharge check device.

[0010]

According to the present invention which achieves the above object, it is a maintenance valve for a fire hydrant device which is provided in a housing having a forward tilting door and is located on the primary side of a fire extinguishing hose. The maintenance valve of the fire hydrant device, characterized in that the maintenance valve is provided such that the discharge inspection device connection port is directed in the horizontal direction toward a side near the maintenance valve of the forward-sloping door. ,.

According to the present invention, when the emission inspection device is connected to the emission inspection connection port of the maintenance valve from the side of the front tilting door of the fire hydrant device from the side near the maintenance valve,
Since the discharge inspection connection port of the maintenance valve faces the worker, the worker will connect the discharge inspection device from the front side of the maintenance valve discharge check connection port. The connection work can be performed in an easy-to-use (easy to apply) posture.

Further, when the discharge inspection device is connected to the discharge inspection device connection port of the maintenance valve and then the discharge inspection device is passed through to perform the discharge inspection, the hose portion of the discharge inspection device is subjected to water pressure. Direction where the hose part of the emission check device is about to extend,
That is, since the front of the connection port for the discharge inspection device of the maintenance valve is oriented in the horizontal direction toward the side near the maintenance valve of the forward-sloping door, the various devices provided on the back surface of the forward-sloping door ( The operating lever and the operating nameplate do not prevent the hose section of the discharge check device from trying to extend straight. Therefore, the discharge inspection work can be performed by passing the water through the discharge inspection device without taking care not to obstruct the various devices on the front door from getting in the way, so that the operation can be easily performed.

The vertical direction of the connection port for the discharge inspection device of the maintenance valve is arbitrary from diagonally upward to diagonally downward, and is set so that the worker can easily connect the discharge inspection device. do it.

Still further, according to the present invention, which achieves the above object, it is a maintenance valve of a fire hydrant device provided in a housing provided with a forward tilting door and located on a primary side of a fire extinguishing hose. The valve is a maintenance valve for a fire hydrant device, wherein the discharge inspection device connection port is provided so as to face vertically upward.

According to the present invention, since the connection port for the discharge inspection device of the maintenance valve is directed vertically upward, the worker can use the weight of the discharge inspection device when connecting the discharge inspection device while connecting the discharge inspection device. Since the discharge inspection connection port of the maintenance valve faces the worker, the worker will connect the discharge inspection device from the front side of the maintenance valve discharge check connection port. The connection work can be performed in an easy-to-use (easy to apply) posture.
