Abstract
The utility model relates to a full-automatic plastic tube pressure-resistance tester. A pressure damping stabilizer and a pressure supplementing electromagnetic valve are arranged between a normally open electromagnetic valve and a pressure transmitter, and a pipeline is added between a liquid box and the outlet of the normally open electromagnetic valve. The pipeline is provided with a return flow electromagnetic valve, and the pressure supplementing electromagnetic valve and the return flow electromagnetic valve are respectively connected with a controller. When media pass through the normally open electromagnetic valve, one part firstly enters the pressure damping stabilizer and then enters a tested pipe. The pressure impact to the tested pipe caused by the media is reduced. When the test stops, the normally open electromagnetic valve and the pressure supplementing electromagnetic valve are closed by the controller and the return flow electromagnetic valve is opened. Therefore, the media in the pipeline can return in the liquid box. The utility model has the advantages of more accurate test results and media loss reduction.
Description
The utility model belongs to the measurement technical field of measurement and test, is a kind of plastic tube compression tester.
Existing plastic tube compression tester is mainly by fluid box, force (forcing) pump, accumulator, normally open solenoid valve, pressure unit and controller constitute, medium in the fluid box enters accumulator by force (forcing) pump, pass through normally open solenoid valve again, pressure unit enters measured tube, pressure unit is communicated with measured tube, and connection controller, controller connects solenoid valve, pressure to measured tube is controlled, this testing machine can be measured the resistance to pressure of plastic tube, but when measured tube broke or stop to test, the dielectric loss amount was big, when medium enters measured tube simultaneously, measured tube is produced stronger compression shock, and test effect is undesirable.
The purpose of this utility model is to provide a kind of test findings accurate, the full-automatic plastic pipe compression tester that the dielectric loss amount is little.
Solution of the present utility model is to be equiped with pressure damping stabilizator and ftercompction solenoid valve between normally open solenoid valve and pressure unit, between the outlet of fluid box and normally open solenoid valve, increase pipeline is arranged, be equiped with return flow solenoid valve on the pipeline, the ftercompction solenoid valve is connected with controller respectively with return flow solenoid valve, and wherein the pressure damping stabilizator is airtight container.When medium passes through normally open solenoid valve, a part directly enters measured tube, the advanced people's pressure damping of another part stabilizator, enter measured tube again, reduced the compression shock of medium to measured tube, when measured tube broke or stop to test, controller was with normally open solenoid valve and ftercompction closed electromagnetic valve, and open return flow solenoid valve, make medium back flow in the pipeline to fluid box.
The utility model can reduce the compression shock of medium to measured tube, improves test mass, makes test findings more accurate, has reduced the loss of medium simultaneously, has reduced operating cost.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing is the utility model synoptic diagram.
The utility model mainly is made of fluid box 1, force (forcing) pump 2, accumulator 3, normally open solenoid valve 4, pressure unit 5 and controller 6, pressure unit 5 is communicated with measured tube 10, between normally open solenoid valve 4 and pressure unit 5, be equiped with pressure damping stabilizator 7 and ftercompction solenoid valve 8, between the outlet of fluid box 1 and normally open solenoid valve 4, increase pipeline is arranged, be equiped with return flow solenoid valve 9 on the pipeline, ftercompction solenoid valve 8 is connected with controller 6 respectively with return flow solenoid valve 9, and wherein pressure damping stabilizator 7 is airtight container.
