Description
Technical field
The utility model relates to a kind of plastic pipes fitting and valve internal hot-water pressure test machine, particularly a kind of plastic pipes fitting and valve internal hot-water pressure test machine that is used to test the heat-resisting and voltage endurance capability of plastic pipe and pipe fitting and valve internal.
Background technology
The life problems of delivering hot water's plastic conduit and pipe fitting and valve is the thing that people pay close attention to.Present test is that sample is coupled together with sample web member and pressure pipeline, put into the isoperibol case of steady temperature water or air, by tank through high-pressure hydraulic pump, electromagnetic valve group, pressure transducer, pressure buffer are irritated and pipeline is formed testing machine, for providing the water of constant pressure, it does experiment, how long sample destroys the probable life of judging sample under this condition in observation, infers its life-span, quality inspection.Its weak point is that this is variant with this equipment test and practical application condition.When especially parts such as slip-knot formula valve were done experiment, the part that individual threads connects was had to use instead metal parts and is done experiment, and can not simulate practical situations.
Summary of the invention
The utility model overcomes deficiency of the prior art, provides a kind of and actual behaviour in service identical plastic pipes fitting and valve internal hot-water pressure test machine.
In order to solve the problem of above-mentioned technology, the utility model is achieved through the following technical solutions: plastic pipe spare internal hot-water pressure test machine comprises tank and high-pressure hydraulic pump, the water under high pressure pump pipeline is connected by the sample web member of well heater with sample one end, the sample web member of the sample other end unloads pressure electromagnetic valve by exhaust and is connected with tank, between well heater and sample web member temperature sensor and pressure transducer is installed.
The utility model also can be achieved through the following technical solutions: between above-described high-pressure hydraulic pump and the well heater water circulating pump is housed, on the pipeline between high-pressure hydraulic pump and the water circulating pump, the pipeline that unloads between the pressure electromagnetic valve by pipeline and the sample web member and the exhaust of the sample other end is connected.
The utility model also can be achieved through the following technical solutions: above-described exhaust is unloaded pressure electromagnetic valve, high-pressure hydraulic pump, well heater, temperature sensor and pressure transducer and is connected with controller by umbilical cable respectively.
The utility model can also be realized by following skill case: above-described water circulating pump is connected with controller by umbilical cable.
Compared with prior art, the beneficial effects of the utility model are: sample is placed in the air under the laboratory environment temperature, and the equal inside of tested parts applies the water that flows of constant temperature, constant voltage, and is consistent with the actual behaviour in service of plastic conduit.For the tubing test, near practical situation.For pipe fitting and valves test, need not change any part and directly test as tubing.Has practical significance.Remove the isoperibol case simultaneously, not only saved the cost of environmental cabinet but also make test setup time shortening.When especially specimen size is big (as the tubing of diameter 630mm, water tank is not less than 6 cubic metres, and the sample that must use crane just can connect is put into water tank).The use present technique can be saved the device fabrication cost more than 50%, and makes test technology simple, can save the use cost more than 50% in test.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawings: 1, pressure electromagnetic valve 8, high-pressure hydraulic pump 9, tank 10, sample web member are unloaded in temperature sensor 2, pressure transducer 3, well heater 4, controller 5, water circulating pump 6, sample 7, exhaust.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: the utility model is made up of following four parts:
1, the ebullator 5 that connects the pipeline have heat-insulation layer is got water, the well heater 3 through having temperature sensor 1, and an end water that flows to sample 6 by the pipeline that has pressure transducer 2 flows back to by the road from the other end, forms circulating water flow.Sample is connected with pipeline by sample web member 10.
2, high-pressure hydraulic pump 8 is connected on the circulation line, and it 9 squeezes into circulation line through high-pressure pump 8 with water from the water source, keeps the circulation line inner pressure constant.On the top of circulation line exhaust is housed, unloads and lay down internal pressure when draining inner air and test termination when pressure electromagnetic valve 7 is used for on-test.
3, the test temperature environment can be finished by the original temperature control in laboratory.
4, controller 4 is connected with pressure transducer 2 with high-pressure hydraulic pump 8 by umbilical cable, the constant pressure in the Control Circulation pipeline; Controller 4 is connected Control Circulation pipeline temperature constant with water circulating pump 5 with well heater 3 and temperature sensor 1 by umbilical cable; Controller 4 also moves with solenoid valve 7 connection control system exhausts and release by umbilical cable.
The utility model has removed heavy big constant temperature environmental cabinet; The wall of the dependence part of sample inside static pressure is transferred heat to inner mode with the temperature of environment, change into by water circulating pump, well heater and necessary pipeline and form the constant temperature current of internal flow, add the constant pressure that hydraulic pressure is kept the current of the inner constant temperature of pipeline to pipeline by a high-pressure pump with sample.Finish test.
During test, earlier sample 6 is connected by web member 10 and pipeline, open solenoid valve 7, open high-pressure hydraulic pump 8,, gas is got rid of totally by solenoid valve, close solenoid valve 7 and high-pressure hydraulic pump 8 to the pipeline intracontour waterflooding; The ON cycle water pump 5 then, and is constant according to the measurement result control heater 3 maintenance water temperatures of temperature sensor 1; Measured value control high-pressure hydraulic pump 8 according to pressure transducer 2 starts/stops, and keeps the constant pressure in the circulation line.Pick up counting this moment, when reaching the time of testing requirements, stops test.
Stopped process is: stop well heater 3, stop high-pressure hydraulic pump 8; Open solenoid valve 7 and unload and put pressure, when treating that specimen temperature reduces, change sample 6 and test or unload sample 6 once more.Process finishes.
