[0005]

[Effects of the operation and the invention] The locking grooves of the pipe joints are respectively locked to the locking portions of the presser fittings, and these pipe couplings are fitted into the joint mounting holes formed in the output port block, so that the output port is formed. The block, the plurality of pipe joints, and the press fittings are integrally assembled, and the pipe joint is firmly attached to the output port block by locking the locking portion and the locking groove.
In particular, a single holding bracket that is superimposed on the output port block
From the bolt holes, which opened at both ends, the output port block
Insert bolts into the above hydraulic equipment through bolt holes at both ends.
Since the screw is tightened, the presser fitting is the same as the washer
Output port block with synthetic resin, etc.
Even if it is made of the same material
Use the presser fittings to lock and
Also tightly tighten the output port block to hydraulic equipment

FIG. 1 shows an embodiment of the present invention. In this embodiment, an output pipe connecting assembly 1 uses a bolt described later to output an output of a pilot type solenoid valve 2 having a main valve 3 and a pilot solenoid valve 4. Attached to port. The valve body 6 of the main valve 3 has an input port P and a discharge port E for the pressure fluid.
A, EB, and output ports A, B opened on the surface opposite to the opening surface of these ports, and valve holes 6a opening these ports, and slidably inserted into the valve holes 6a. The main valve body 8 is actuated by pilot fluid pressure acting on piston storage boxes 7a and 7b mounted on both sides of the valve body 6,
The piston 9a is provided in the piston storage box 7a, and the piston 9b having a smaller diameter than the piston 9a is provided in the piston storage box 7b.
Are slidably inserted.

The pilot solenoid valve 4 has a pilot input port, a pilot output port, and a pilot discharge port (all not shown). When the solenoid is excited, the pilot input port and the pilot output port communicate with each other to supply pilot fluid. When the solenoid is de-energized, the pilot output port and the pilot discharge port communicate with each other to form a well-known three-port solenoid valve through which the pilot fluid is discharged to the outside. The piston storage box 7b communicates with the piston storage box 7a.
0b communicates with the input port P.

The output pipe connection assembly 1 mounted on the valve body 6 has joint mounting holes 14, 14 and bolt holes 13.
a, 13a, and one-touch fittings 15, 1 fitted in fitting mounting holes 14, 14, respectively.
5 and a presser fitting 16 for locking these pipe joints.
When the holding member 16 and the holding member 16 are attached to the valve body 6, the joint attachment holes 14, 14 individually communicate with the output ports A, B. The body 20 of the one-touch fitting 15 has an O-ring 2 that fits tightly into the locking groove 21 and the joint mounting hole 14 therebelow.
The guide 23, the collet 24, the metal chuck 25, and the release bush 26 are sequentially attached from the outside of the body 20 toward the center. When a tube (not shown) is inserted through the release bush 26, ,
A plurality of locking claws formed at the tip of the chuck 25 are locked on the outer peripheral surface of the tube, and the tube is sealed by the packing 27. When the release bush 26 is pushed in, the locking of the tube by the locking claw is performed. It is configured as a well-known pipe joint that can be released and the tube removed. The pressure foot 16, without a plan view S-shape, both

When the one-touch fitting 15 is changed, the bolts 17 , 17 are removed, and the locking between the locking portion 30 of the press fitting 16 and the locking groove 21 of the one-touch fitting 15 is released. Since it can be removed from the joint mounting hole 14,
It can be replaced with another pipe joint 15 having a desired pipe diameter. In this case, since the diameter of the joint mounting hole 14 of the output port block 13 does not change, by preparing a plurality of types of pipe joints 15,... Can be changed. Therefore, the number of types of the one-touch fitting 15 is reduced, so that inventory management is facilitated.
