The present invention for achieving the above object is in the connecting device for coupling the intake and exhaust pipe to the solenoid and the valve body, the solenoid and the valve body is composed of a connecting hole which is configured to be compressed to the fastening hole Lose.

The connector includes a seating member in which a single-layered stone piece is formed on an outer circumferential surface to be seated in a fastening hole, first and second connecting members inserted into the seating member and pressed into the seating member, and an intake / exhaust pipe is connected in the first connecting member. It is to provide a hydraulic or pneumatic pipe connection device of the solenoid valve, characterized in that consisting of the mounting member is mounted.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, a fastening hole 21 is formed so that the intake pipe 6 and the exhaust pipe 6a are installed, and fastening pieces 22 are formed before and after both sides, and grooves 23 at the rear of the fastening pieces 22 are formed. At least one valve body (2) formed with; A fastening member (3) seated in the groove (23) and having a thread formed on its inner circumference; A fastener (4) fitted to the fastening piece (22) to connect and fix each valve body (2) to each other by bolts (7) with threads of the fastening member (3); The inlet pipe 6 and the exhaust pipe 6a are connected to the solenoid 5 and the main body 2 of the solenoid valve device 1 composed of a solenoid 5 which is fastened to the upper end of the valve body 2 by a bolt 7a. In the connecting device for connecting), the solenoid 5 and the connector 10 which is pressed against the fastening hole 21 formed in the valve body (2).

The connector 10 is a seating member 11 to be seated in the fastening hole 21, and the first and second connections are inserted into the seating member 11 and connected to the intake and exhaust pipes 6 and 6a. The members 12 and 12 'and the mounting member 13 mounted so that the intake / exhaust pipes 6 and 6a are connected to the first connecting member 12 are provided.

In addition, the rubber packing 14 is mounted to maintain the airtightness on one side outer circumference of the seating member 11, and the rubber packing 14a is also mounted on the outer circumferential surface of one end of the second connection member 12 ′. .

The seating member 11 has a single-layered stone piece 11a configured to be compressed with the inner circumferential surface of the fastening hole 21 when seated by the fastening hole 21 on the outer circumferential surface, and a through hole 11b is formed at the center thereof. The mounting groove 11c is configured such that the rubber packing 14 is mounted on the circumference.

The first and second connection members 12 and 12 'may have a through hole 12a formed at the center thereof, and the rubber packing 14a may be mounted around one end of the second connection member 12'. The mounting piece 12b is comprised so that it may be.

In addition, the outer circumferential surface of the first connecting member 12 is configured to protrude the pressing piece 12c so as to prevent the detachment when the connecting member 12 is mounted into the through hole 11b of the seating member 11, the inner peripheral surface The separation preventing piece 12d is configured to prevent the separation when the intake / exhaust pipes 6 and 6a are attached to the mounting member 13.

In the accompanying drawings, reference numeral 8 denotes a connecting plate which is fastened to both sides of the valve body 2, and 9 denotes a gasket for maintaining airtightness.
