BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piping connection device for a fire-fighting operation valve, and more particularly, to a piping connection device for a fire- So that the direction of the fluid can be easily confirmed after the piping is installed on the operated valve so that the check of the water pressure and the check and replacement according to the leakage can be smoothly performed To a piping connection device for a fire-fighting operated valve.

Generally, fire-fighting facilities are installed in the buildings to prepare for the occurrence of fire. Among these fire-fighting facilities, there are sprinkler facilities which are installed and used the most.

In the sprinkler system, when the thermally conductive portion of the sprinkler head is opened due to fire in a state where the predetermined amount of pressurized water is always filled in the piping system, pressurized water is discharged and the water flow detection device is activated to generate an alarm, And the water is continuously sprayed through the head.

The water flow detection device of the sprinkler facility is a device that automatically detects the water flow in the pipe due to fire and generates an alarm signal.

On the other hand, Korean Utility Model Registration No. 20-0447360 (Jan. 20, 2010) discloses a pipe connecting pipe for a fire-fighting ready valve.

However, such a conventional pipe connector has a problem in that it is difficult to quickly cope with changes in hydraulic pressure, leakage and the like due to leakage or the like, since the direction of the fluid can not be easily known after the pipe is installed in the operable valve.

However, in the present invention, the 'pipe connection port for the fire-fighting ready valve' is replaced with the 'pipe connection device for the fire-fighting operation valve' among the configurations disclosed in the above-mentioned registered utility model No. 0447360, And a description of the operation is further included, and this part is the most important constitutional feature.

Accordingly, the device structure, characteristics, and operating relationship described below will be referred to as the above-mentioned registration utility model No. 0447360, and the configuration related to the main features of the present invention will be described in detail at the rear end.

1 to 2, a piping connection device (hereinafter referred to as "connection device") of a fire-fighting operation valve according to the present invention is mounted on a primary pipe 2 of a fire- (100) for connecting pipes of an actuation valve (1) for fire fighting which automatically detects a water flow phenomenon and issues an alarm to a signal through an alarm switch (4), and the body (100) The discharge port 102 and the first and second minute mechanisms 103 and 104 are formed.

The inlet (101), the outlet (102) and the first and second minute devices (103, 104) can be understood as a tube having both ends open.

The second branching mechanism 104 is formed in a direction perpendicular to both the inlet 101, the outlet 102 and the first branching mechanism 103.

The inlet (101), the outlet (102), and the first and second distributing mechanisms (103, 104) are formed with threads on the inner peripheral surface.

The inlet (101), the outlet (102), and the first and second distributors (103, 104) may have threads formed on their outer circumferential surfaces.

The connection device connects the connection pipe to the inlet port 101 and the outlet port 102 to form a main pipe when a piping for arranging an application article is required.

The first branch mechanism (103) connected between the main pipelines is assembled with an application article oriented in one direction, and the second branch mechanism (104) Thereby assembling another one of the usable articles.

The use article may be a pressure gauge or the like, and may be directly connected to the first and second minute mechanisms 103 and 104 to be assembled and connected.

Alternatively, when the installation site is located far from the main pipe, or when there is an obstacle such as the fire-fighting operation valve 1, other connecting parts between the distributing devices 103 and 104 and the usable goods, for example, , El arch, etc., can be connected.

The connection device includes a first branch mechanism 103 for allowing a part of the introduced fluid to be discharged through a different path from the discharge port 102 and a second branch mechanism 103 for discharging the second branch mechanism 104 in a direction different from the first branch mechanism 103. [ So that it is possible to install and arrange the application articles so as to face the first and second minute mechanisms 103 and 104 in different directions respectively.

In addition, the connection device can efficiently install the piping of the use article even in a place where there is an obstacle such as a fire-operated valve, and can reduce the piping construction cost by reducing the number of piping connection parts and the number of piping connection processes And the piping joint portion is greatly reduced, so that stable piping can be achieved without leakage of the fluid.

2, an inlet 101 is connected to a main pipe 8 connected to a primary pipe 2 of a fire-fighting operation valve, and an outlet 101 is connected to the outlet 102. [ The differential pressure gauge 6 is assembled.

In the present invention, the configuration of the checking unit 200 for confirming the traveling direction of the fluid passing through the body 100 is further implemented, as shown in FIGS.

This is because the connection device is connected to the operation valve 1 so that fluid flows from the inlet 101 toward the outlet 102 or flows from the outlet 102 to the inlet 101 As shown in FIG.

In addition, when the connecting pipe is connected to the inlet 101 and the outlet 102 to form a main pipe, the connection device can not easily confirm the flow of the fluid while being far from the operable valve 1 Because.

As a result, the connection device can not be smoothly inspected and replaced due to a change in water pressure, leakage, or the like.

The checking unit 200 can easily check the traveling direction of the fluid flowing in the connecting device in a state where the connecting device is installed with the piping on the operating valve 1, So that replacement can be performed smoothly.
