Advantage of the present utility model and beneficial effect are: the lasting Withstand test device of this PE plastic pipe has that automaticity is high, control accuracy is high, Sustainable Exploitation platform, good reliability, appearance design is attractive in appearance, compact, floor area is little; Control parameter, the test result directly host computer in automatically controlled part are inputted and are read, and operation is simple.
The accompanying drawing explanation
Fig. 1 is the general structure schematic diagram of the lasting Withstand test device of the utility model PE plastic pipe;
Fig. 2 is the water route control chart of the lasting Withstand test device of the utility model PE plastic pipe.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in general structure Fig. 1, the utility model is the lasting Withstand test device of a kind of PE plastic pipe, includes controller 3, attemperater 13, connection sealing joint 12, constant pressure pump 1 four major parts.
Controller 3 comprises hydraulic pressure water route control section 4 and automatically controlled part 5, and automatically controlled part 5 is controlled hydraulic pressure water route control section 4 by control circuit 10.Automatically controlled part 5 mainly comprises host computer 6, Programmable Logic Controller 8, printer 9, control circuit 10, pressure signal is that the pressure transducer 18 in hydraulic pressure water route control section 4 collects the analog quantity current signal, by compiling functional module in controller (PLC) 8, analog signals is transferred to digital quantity signal, in Programmable Logic Controller 8, internal relay output switch amount signal is controlled the keying of solenoid valve 18 and constant pressure pump 1.Control parameter by host computer 6 input original tube data (tube outer diameter, wall thickness) and testing standard (ring stress or fluid pressure, test duration), be sent to Programmable Logic Controller by dedicated communications cable 7, by Programmable Logic Controller 8 programs, calculate the control parameter.When reaching the upper of control parameter, controlled pressure prescribes a time limit, start self-clocking, by directly reading the test result of pressure, time and temperature on host computer 6, when reaching setting-up time, system stops timing automatically, and the test result that host computer 6 shows can be by by printer 9 printouts by telecommunication cable 7.
