At present, tubing compression tester primarily of controller, constant temperature water tank, fixture, hydraulic system composition, concerning with a good tubing compression tester, fixture and hydraulic system most important, direct affect equipment serviceable life, test accuracy and stability.The impermeability of fixture is inadequate, easily produces experimental mistake.(application number is that the Chinese patent of CN200820076378.X discloses a kind of plastic pipes fitting and valve internal hot-water pressure test machine) on market, comprise tank and high-pressure hydraulic pump, it is characterized in that water under high pressure pump pipeline is connected with the sample web member of sample one end by well heater, the sample web member of the sample other end unloads pressure electromagnetic valve by exhaust and is connected with tank, is provided with temperature sensor and pressure transducer between well heater and sample web member.Although this testing machine can Preliminary Simulation and developmental tube pipe, its control accuracy is lower, and the amplitude of control also cannot reach the requirement at present to tubing, easily causes the damage of testing machine itself.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of easy to adjust, and impermeability is superior, the tubing compression tester of durable.
For achieving the above object, the utility model provides following technical scheme: a kind of tubing compression tester, comprise fixture, hydraulic system, described hydraulic system comprises feed source, gas cap liquid supercharge pump, main distributing valve block, little distribution valve block, described feed source, gas cap liquid supercharge pump, main distributing valve block, little distribution valve block connects successively, main distributing valve block is connected with large accumulator successively, stop valve, retaining valve, little distribution valve is connected with entering water electromagnetic valve successively, little accumulator, pressure transducer, pressure release electromagnetic valve, described fixture is arranged between entering water electromagnetic valve and pressure release electromagnetic valve.
Preferably, described fixture comprises end cap, gripping sleeve, clamping disk(-sc), trim ring, O-ring seal, and described gripping sleeve end is connected with slippage before and after trim ring, described O-ring seal arrange with trim ring bottom, described clamping disk(-sc) is sheathed on gripping sleeve, and described clamping disk(-sc) is flexibly connected with end cap.
Preferably, the madial wall of described gripping sleeve is provided with pawl.
Preferably, the lateral wall of described gripping sleeve is obliquely installed.
Compared with prior art, the beneficial effects of the utility model are: by increasing advanced gas cap liquid supercharge pump, hydraulic pressure can be increased by air pressure, control meticulousr, regulated by main distributing valve block and little distribution valve block two groups simultaneously simultaneously, reach coarse adjustment, thin tuning cooperatively interacts, Stress control is meticulousr, the response time is short, be swift in response, fixture is arranged between entering water electromagnetic valve and pressure release electromagnetic valve, effectively can change the pressure in test specimen, fixture can be used for a long time, strengthen result of use, increase serviceable life.
Accompanying drawing explanation
Fig. 1 is the hydraulic system block diagram of the utility model tubing compression tester embodiment;
Fig. 2 is the cut-open view of the fixture of the utility model tubing compression tester embodiment.
In figure 1, hydraulic quick coupler, 2, end cap, 3, O-ring seal, 4, trim ring, 5, gripping sleeve, 6, clamping disk(-sc), 7, screw, 8, test specimen.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model tubing compression tester embodiment is described further.
Tubing compression tester is primarily of controller, constant temperature water tank, fixture, hydraulic system composition, and controller and constant temperature water tank are to belong to prior art, and therefore not to repeat here.
A kind of tubing compression tester, comprise fixture, hydraulic system, described hydraulic system comprises feed source, gas cap liquid supercharge pump, main distributing valve block, little distribution valve block, described feed source, gas cap liquid supercharge pump, main distributing valve block, little distribution valve block connect successively, main distributing valve block is connected with large accumulator, stop valve, retaining valve successively, little distribution valve is connected with successively entering water electromagnetic valve, little accumulator, pressure transducer, pressure release electromagnetic valve, between described entering water electromagnetic valve and pressure release electromagnetic valve, is provided with fixture.Gas cap liquid supercharge pump is connected with air compressor machine, and air compressor machine provides gases at high pressure to gas cap liquid supercharge pump, and the hydraulic pressure flowing through gas cap liquid supercharge pump is increased, and water under high pressure is again through main distributing valve block, and large accumulator wherein plays the effect of voltage stabilizing and pressure accumulation.When entering water electromagnetic valve is opened, water under high pressure enters test specimen 8, and entering water electromagnetic valve is closed immediately, and when the pressure in test specimen 8 reduces, solenoid valve opens ftercompction immediately.Carry out dual regulation by main distributing valve block, little distribution valve block, play the effect of good steady pressure and supplementary pressure.
Because to test specimen 8, easy damage equipment appears that in pressurization impermeability weakens, the catastrophic failure leaked air, in general all fixtures, and the serviceable life reducing equipment, its main cause makes fixture to the reason of the grip of test specimen 8 and impermeability deficiency.
As shown in Figure 2, fixture comprises end cap 2, gripping sleeve 5, clamping disk(-sc) 6, trim ring 4, O-ring seal 3, is provided with hydraulic quick coupler 1, makes rapidly easy for installation in the middle of end cap 2, improves the installation effectiveness of test specimen 8.Described gripping sleeve 5 end is connected with slippage before and after trim ring 4, after fixture put into by test specimen 8, described O-ring seal 3 arrange with trim ring 4 bottom, O-ring seal 3 forms sealing at test specimen 8 lateral wall, trim ring 4 forms second sealing effectiveness at test specimen 8 lateral wall, described clamping disk(-sc) 6 is sheathed on gripping sleeve 5, simultaneously when clamping disk(-sc) 6 toward test specimen 8 axial direction motion time, gripping sleeve 5 lateral wall is obliquely installed, step up cover will move inward, promote trim ring 4 and O-ring seal 3, make O-ring seal 3 deformation, make sealing effectiveness more remarkable, gripping sleeve 5 sidewall is provided with pawl, make gripping sleeve 5 effectively can catch test specimen 8 sidewall, play anti-skidding effect, described clamping disk(-sc) 6 is connected by screw 7 with end cap 2, can be effectively fixing by clamping disk(-sc) 6.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
