The present invention use process is as follows：
Gate valve or shut-off valve hand wheel type sample 29 are placed in sample mobile station 7 up and down, it is defeated to display PLC controller 56
Enter gate valve or 29 specifications and models information of shut-off valve hand wheel type sample such as valve sample and imports and exports horizontal axis away from valve bottom
Distance A value etc., the flexible work of spindle motor II 11 make upper and lower sample mobile station 7 be moved to gate valve or shut-off valve hand wheel type sample
29 inlet and outlet horizontal axis stop working with flexible spindle motor II 11 rear in a horizontal plane substantially with 25 axis of moving tube, with even
Connection device such as pipe connects the installation gate valve such as II 27, loose joint 28 or shut-off valve hand wheel type sample 29, presses display PLC controller 56
In test start button, each component for being controlled of display PLC controller 56 enters working condition, air pump 1, water booster pump 3
After pressure sensor IV 60, pressure sensor III 61 reach programming setup pressure value, the spindle motor I 47 that stretches works for work, hangs down
Straight telescopic shaft I 44 moves down and the component for driving I 44 lower end of vertical telescopic axis to connect moves down, telescopic shaft after being displaced downwardly to set distance
Motor I 47 stops working, i.e., monitoring camera II 37 is to the image data that display PLC controller 56 transmits：It is Pneumatic parallel double
The pneumatic-finger a33 of effect clamper 35 shows that PLC controller 56 instructs flexible spindle motor I after reaching at valve rotation handwheel 32
47 stop working, and display PLC controller 56, which controls solenoid valve II 59 and opens, passes through tracheae 50 to the gas supply of solenoid valve block 57, display
PLC controller 56 controls solenoid valve block 57 and gas source is sent to Pneumatic parallel double acting folder through pneumoelectric rotary joint 42 by tracheae 50
Holder 35 makes to move horizontally the shortening of bar 34, and both sides move horizontally the fixed pneumatic-finger a33 in 34 end of bar will be parallel and near to pneumatically
The inner shape of finger a33 is arc 52, and cushion 51 is fixed on arc 52, is equipped in the centre of cushion 51 soft
Property pressure sensor 74, handwheel 32 and make pliable pressure when the cushion 51 on two pneumatic-finger a33 touches valve rotation
Sensor 74 shows that PLC controller 56 controls solenoid valve block 57 and keeps the pressure value after reaching authorized pressure value.Show PLC control
Device 56, which controls hollow shaft, which surveys the work of torque motor 40, rotates Pneumatic parallel double acting clamper 35 and rotates handwheel with movable valve
Valve sample 29 is closed in 32 rotations, and PLC controller 56 controls electric controlled regulating valve 54 and solenoid valve I 21 is in the open state, when
After pressure sensor II 53 and pressure sensor I 26 reach regulation pressure difference to the data that display PLC controller 56 transmits, display
PLC controller 56, which controls hollow shaft, which surveys the work of torque motor 40, opens valve sample 29, and water flows into reservoir 15 through water pipe 4
Into water booster pump 2, such water circulation use.Display PLC controller 56, which controls hollow shaft, which surveys the work of torque motor 40, makes valve
It is that the one action of valve sample 29 recycles that sample 29, which is opened to closing, and rate is not more than 6 times/min, when reaching 5000 tasks
Hollow shaft surveys torque motor 40 and stops working after circulation, and display PLC controller 56 is according to programming to each cycle hollow of sample 29
Axis is surveyed the image data that the force value that torque motor 40 obtains and monitoring camera I 30 and monitoring camera II 37 transmit and is carried out automatically
Comparative analysis is made whether situations such as operational torque goes beyond the scope or leaks conclusion.
Its installation steps and test procedure when detecting valve and being ball valve or butterfly valve and check valve manual handle type sample 70
With gate valve or shut-off valve hand wheel type sample 29, but it is unique the difference is that Pneumatic parallel double acting clamper 35 changes eccentric gas into
It is detailed as shown in Figure 4 to move parallel double acting clamper 69.
When detecting power drive type valve sample 71, the step and sample 70 and sample that are mounted on test pipeline 25
29 is identical, but the working cycles movement of valve sample 71 not through flexible spindle motor I 41, Pneumatic parallel double acting clamper 35 or
Eccentric Pneumatic parallel double acting clamper 69 and hollow shaft survey torque motor 40 to complete but by control line 73 by showing PLC
The control of controller 56 is completed to be detailed in described in Fig. 5, the image and pressure that display PLC controller 56 is transmitted according to monitoring camera I 30
Sensor I 26, pressure sensor II 53 situation of change to make power drive type valve sample 71 little in actuation cycle rate
Add up in 5000 tasks circulation whether there is the slow movement time to have leakage beyond specified value or valve sample 71 in 6 times/min
The conclusion of situation.
The device is suitable for the 5000 tasks circulation of the progress of various specifications valve used in automatic sprinkler system
Test during test is without human intervention automatically performed judgement, reduces labor intensity, reduces human interference factor, improves
Detection automation improves test mass and efficiency.
