The compression member 250 is annular and the lower end of the compression member 250 is configured to sufficiently compress the packing member 210 to have a width enough to apply a predetermined force to the packing member 210 desirable.

1, in order to secure the watertightness of the branch pipe 100, the main pipe connecting device for branching the pipe 100 includes a connecting pipe 200 And a packing member 390 mounted on the outer periphery of the joint pipe 310. The packing member 390 is screwed to the other side of the tightening pipe 230 and has an inner hollow portion to which the branch pipe 100 is inserted. And a joint fixing pipe (330) screwed to the joint pipe (310).

The branch pipe 100 is inserted into the inner hollow portion of the coupling pipe 310 and the male screw portion 203 or the male screw portion 203 of the coupling pipe 200 is inserted into the inner or outer circumferential surface of the coupling pipe 310. And a threaded portion that is screwed with the female threaded portion 231 of the fastening pipe 230 is formed.

That is, the threaded portion of the coupling pipe 310 may be selectively formed with the female threaded portion 313 or the male threaded portion 311 depending on whether the threaded portion of the coupling pipe 310 is screwed to the coupling pipe 200 or the coupling pipe 230 have.

More specifically, when the coupling pipe 310 is screwed to the male threaded portion 203 of the coupling pipe 200, as shown in FIGS. 1 to 3, A female screw portion 313 corresponding to the male screw portion 203 and a male screw portion 311 corresponding to the female screw portion 333 of the joint fixing pipe 330 are provided on the outer peripheral upper end portion of the joint pipe 310 .

The third watertight portion for securing the watertightness between the connection pipe 200 and the branch pipe 100 may further include a connection packing 370 inserted between the upper end of the connection pipe and the lower end of the branch pipe. .

That is, a connection pipe packing 370 is further inserted between the connection pipe 200 and the branch pipe 100 to form a third watertight portion. The connection pipe 370 is connected to the connection pipe It is possible to prevent the leakage occurring due to the mechanical contact between the connecting pipe and the branch pipe.

In other words, since the coupling pipe 200 and the branch pipe 100 are designed to have a circular structure, if the end portion of the coupling pipe 200 and the end portion of the branch pipe 100 are not made into a complete straight structure A gap may be formed in a contact portion between the connection pipe 200 and the branch pipe 100 to prevent leakage. In order to solve the problem, the present invention is characterized in that a connection packing 370 So that the connection packing 370 functions as an airtight seal between the end of the connection pipe 200 and the end of the branch pipe 100 so that complete watertightness is achieved.

The connection packing 370 may be formed in a cap shape to connect between the connection pipe 200 and the branch pipe 100.

That is, the connection packing 370 is formed in the shape of a circular ring, and a cap having a space is formed therein. The lower end of the connection pipe 200 and the lower end of the branch pipe 100 are connected to each other by a soft packing The inner circumference of the connection pipe 200 and the inner circumference of the branch pipe 100 are commonly connected to each other so that the gap between the connection pipe 200 and the branch pipe 100 It can be washed once more so that the watertight ability can be improved much more.

In other words, the connection packing 370 of the present invention enables the first water tightness by connecting the inner circumference of the connection pipe 200 and the inner circumference of the branch pipe 100 by using the vertical plane, 200) and the end portion of the branch pipe (100) are commonly connected to each other to enable the second water tightness, thereby maximizing the watertightness efficiency between the connection pipe and the branch pipe. At this time, the connection packing is formed into a circular ring shape and at the same time, the ring cross-section is formed into a cap shape, so that the connection pipe and the branch pipe are combined and cushioned while being buffered, thereby maximizing the watertightness capability.

In order to check whether the connection pipe 200 and the branch pipe 100 are closely coupled to each other, a pressure sensing sensor 400 is installed at one end of the connection packing, and information on the pressure sensing sensor is checked And an error signal automatic output unit 1000 for outputting an alarm signal when the controller determines that the contact is not properly performed.

The error signal automatic output unit 1000 is configured to continue the alarm signal if the error condition is not released.

The configuration of the error signal automatic output unit 1000 of the present invention is as follows.

A contact power supply unit 1101, a contact error signal output unit 1102, an oscillation transformer 1103, a relay operation switching unit 1108, a relay switch 1107, a first circuit connection switch sw1, A communication terminal power switch sw2, and a power source holding switching section 1118. [

The power supply unit 1101 applies a power supply signal by itself.

The contact error signal output unit 102 receives a signal from the control unit 500 and switches the power supply circuit when it is detected that the connection state of the connection pipe and the branch pipe is incomplete from the pressure sensor.

When the power switch is turned on, the oscillation transformer 1103 is supplied with electric power to output a boosted AC current.

The switching unit 1108 for relay operation is connected to the output terminal of the oscillation transformer 1103 and is turned on by electrical supply.

The relay switch 1107 is installed at an output terminal of the relay operation switching unit 1108 and generates a magnetic force.

The first circuit connection switch (sw1) performs a function of energizing the circuit by pulling the iron wire by the relay switch (1107).

The power switch for outputting the error signal sw2 induces an error signal to be displayed by supplying power to the error signal output control unit 1140 while the iron strip is pulled by the relay switch 1107. [

The power supply switching unit 1118 is connected to the base end of the first circuit connection switch and the emitter end and the collector end are connected to the oscillation transformer 1103 and the relay operation switching unit 1108, The wire is pulled by the operation of the switch 1108 to form a closed circuit while switching is turned on, and then the operation of the relay switch 1107 is stopped. At this time, if the first circuit connecting switch sw1 and the error signal output power switch sw2 are forcibly turned off, the closed circuit is broken while the closed circuit is broken and the relay operating switch 1108 is turned on and the relay switch is turned on The first circuit connecting switch sw1 and the error signal output power switch sw2 are turned on to induce the error signal to be output continuously.

Hereinafter, the operation of the error signal automatic output unit 1000 will be described.

First, when the contact error signal output unit 1102 is turned on, a DC power source is connected to supply power to the oscillation transformer, and a high voltage is applied to the secondary side of the oscillation transformer.

The power source induced on the secondary side becomes a DC power source of a half wave through a rectifying diode, and this half wave DC power source becomes a more stable DC power source due to the charging and discharging action of the condenser.

This DC power source is applied to the anode terminal of the thyristor through the coil of the relay switch 1107, while the DC power source charges the capacitor through the resistor. The elevated voltage passes through the die and triggers the switching section 1108 for relay operation so that the node node and the cathode node are switched so that the operation of the relay switch is made, The circuit connection switch sw1 and the error signal output power switch sw2 are turned on to apply power to the error signal output control unit 1140 to display an error signal.

When the first circuit connection switch sw1 is activated, a base end of the power supply maintaining switch 1118 is activated, and a closed circuit is induced in the emitter end and the collector end of the power supply holding switch 1118 to supply power to the transformer Off.

That is, a voltage between the resistor 1109 and the capacitor 1110 flows through the diode 1120 to flow between the emitter terminal and the collector terminal of the power source holding switching unit 1118, and the resistance between the resistor by the bypass and the capacitor When the voltage between the resistor and the capacitor is lowered, the trigger signal to the switching unit for relay operation 1108 is stopped, so that the node end and the tail end are turned off and the current flows to the relay switch 1107 So that the power supply is continuously stopped for switching.

On the other hand, if the operator turns off the first circuit connecting switch and the error signal output power switch during the error signal output, there is no current flow in the closed circuit, and accordingly, the bias voltage flowing between the emitter end and the base end of the power- And the power supply switching unit 1118 is turned off.

The power supply switching unit 1118 is turned off to remove the bypass voltage between the resistor and the capacitor through the diode 1120 and the voltage is charged in the capacitor 1110.

The charged voltage causes a break-over phenomenon of the die 1111 and a trigger signal is output from the die to the switching section 1108 for auxiliary switch operation to move the iron piece, while maintaining the closed circuit, and at the same time, So that the error signal display unit 1150 can be continuously operated.

That is, according to the present invention, if the error factor is not cured, the warning sound is continuously output, and the user can always operate the branch connection device after healing the error factor.
