Embodiment
Below in conjunction with accompanying drawing the utility model is made and to further specify.
With reference to figure 1 and Fig. 2.Clip hydrostatic test platform according to the utility model one embodiment comprises tank 1, water pump 2, water pump drive motor 3, water inlet pipe 41, testing tube 42, rubber tube 43, return pipe 44, first water pressure gauge 51, second water pressure gauge 52, pressure transducer 6, first solenoid valve 71, second solenoid valve 72 and PLC controller 8.
The entrance of water pump 2 is communicated with tank 1, and the outlet of water pump 2 is communicated with an end of water inlet pipe 41.The other end of water inlet pipe 41 is communicated with an end of first solenoid valve 71, and the other end of first solenoid valve 71 is communicated with an end of testing tube 42 by first arm 45, by the end connection of second arm, 46 second solenoid valves 72.The other end of second solenoid valve 72 is communicated with an end of return pipe 44, and the other end of return pipe 44 is communicated with tank 1.
As shown in Figure 3, the other end of testing tube 42 sealing is provided with through hole 420 at the tube wall of testing tube 42; Rubber tube 43 is set on the testing tube, and a pair of tested clip 91,92 is stuck in the two ends of this rubber tube 43.
In conjunction with shown in Figure 4, first water pressure gauge 51 and pressure transducer 6 are arranged on the water inlet pipe 41, and second water pressure gauge 52 is arranged on first arm 45.The signal output part of pressure transducer 6 is electrically connected with the input end of PLC controller 8.The signal input part of the signal input part of the signal input part of water pump drive motor 3, first solenoid valve 71 and second solenoid valve 72 is electrically connected with the output terminal of PLC controller 8.
In a preferred embodiment, clip hydrostatic test platform of the present utility model also is provided with retaining valve 73 and surplus valve 74.One end of retaining valve 73 is communicated with the other end of water inlet pipe 41, and the other end of retaining valve 73 is communicated with an end of first solenoid valve 71 and an end of surplus valve 74 respectively, and the other end of surplus valve 74 is communicated with return pipe 44.Surplus valve 74 can adopt proportional pressure control valve.
