In this state, when the knob of the pressure knob is rotated in the locking direction to press the pressure jig directly under the connecting rod contacting the end thereof, the external of the electronic control valve is caused by an external force transmitted to the electronic control valve through the pressure jig. Since the O-ring members O1, O2, and O3 provided on the surface are completely in contact with the inner surface of the mounting hole, the first, second and third connection holes 121a, 121b, 121c formed on the outer surface of the first jig and The first, second and third ports P1, P2 and P3 of the corresponding solenoid control valves are isolated from each other.

The output unit 130 is branched from the first branch line (119a) and the second three-way valve 132 in the middle of the length of the compressed air discharge line 131 for discharging the compressed air through the first port (P1) The first and second branch discharge lines 133a and 134a connected to the second three-way valve 132 are provided with a first flowmeter 133 and a second flowmeter 134, respectively, and are controlled by external signals. After the discharge of the compressed air discharged from the electronic control valve (V) is to measure the flow rate of the discharged compressed air.

A third ball valve 137 is opened and closed to guide the discharge to the auxiliary discharge line (134a) or the discharge air to the compressed air discharge line 131 side.

As shown in FIG. 5A, the compressed air, which is pressure-controlled first and second by the first three-way valve 118 of the input unit 110, is input to the third port P3 through the third branch line 119c. When the compressed air which is not electronically controlled through the first and second ports P1 and P2 is discharged, the first and second ports P1 and P2 are completely opened in the electronic control valve to have the maximum opening size. Therefore, the flow rate of the compressed air discharged through this is maximized.

As shown in FIG. 5B, the compressed air, which is pressure-controlled first and second by the first three-way valve 118 of the input unit 110, is input to the third port P3 through the third branch line 119c. When the compressed air is discharged through the first and second ports P1 and P2 and the compressed air is discharged, the first and second ports P1 and P2 are partially opened by the spool of the electronic control valve so that the opening size is small. As a result, the flow rate of compressed air discharged through it is reduced.

In this state, when the second ball valve 135 provided in the auxiliary discharge line 135a is closed, and the third ball valve 137 provided in the first branch line 119a is opened, the first port Compressed air discharged through the air is discharged to the atmosphere by the third three-way valve 136 of the first branch line (119a) connected to the first port (P1), while discharged through the second port (P2) Compressed air is discharged to the extruded air discharge line 131 connected to the first branch line (119a), and then to the first branch discharge line (133a) in which the first flow meter (133) is installed by the second three-way valve. The discharge flow rate of the compressed air is measured by the first flow meter 133, which is a discharge flow rate and is a low flow meter which measures the low flow compressed air.

As shown in FIG. 5C, the compressed air, which is pressure-controlled first and second by the first three-way valve 118 of the input unit 110, is input to the second port P2 through the second branch line 119b. When the compressed air is discharged by electronic control only through the first port P1, the first port P1 is partially opened by the spool of the electronic control valve, and thus the compressed air is discharged through the opening. Will reduce the flow rate.

In this state, when the second ball valve 135 provided in the auxiliary discharge line 135a is closed, and the third ball valve 137 provided in the first branch line 119a is also closed, the second ball valve 135 is closed.
