Description
Technical field
The utility model relates to a kind of pipe fitting manufacturer production quality control and breadboard check utensil of being applicable to, relates in particular to U-PVC pipe fitting load performance and detects anchor clamps.
Background technology
Along with continuing to increase of national water conservancy construction paces, the high-efficiency water-saving irrigation technique constantly obtains promotion and application, and the water-saving irrigation product has become a very important part in the modern agriculture construction.The U-PVC pipe fitting is being brought into play crucial effects in the agricultural construction in modern times as indispensable one big class in the saving product of water, and its product quality enjoys the concern of enterprise and businessman.Load performance is an important indicator of weighing the pipe fitting quality as one of conventional sense project of U-PVC pipe fitting.In the routine check; Traditional detection method is: earlier pipe fitting and required tubing surface of contact are polished with 40 purpose sand paper; To increase the friction force of bonding plane, burnishing part is cleaned with acetone soln in the back, to be dried after; With PVC glue pipe fitting and tubing are carried out bonding, after at room temperature place at least and make an experiment behind the 24h.Several point defects below this method can occur: (1) in inspection operation, because of early stage pipe part need place 24h at least after bonding, make that to detect set-up procedure too consuming time, influence the promptness of assay, be unfavorable for producing and follow the tracks of and guidance; (2) the once bonding success ratio of pipe fitting can't be guaranteed, and the situation that the abutting edge leaks in the hydrostatic test process, often occurs, if the abutting edge leaks or cracking appears in bonding tubing, will cause the failure of pipe fitting hydrostatic test, and all that has been achieved is spoiled; (3) in the bonding process, smear very fewly like PVC glue, the abutting edge leaks easily; PVC glue is smeared too much, can converge into shallow bid glue and flow to pipe fitting or pipe material inner wall, the experiment proof; Be easy to turn white with pipe fitting under the equal pressure or pipe material inner wall glue impression place and break, influence test accuracy; And in this process, the glue consumption is difficult to control, and is easy to so causes test failure; (4) for φ 90 above pipe fittings; Need the outer wall of tubing, the inwall of pipe fitting to be polished at the bonding initial stage with 40 order sand paper; Increase the friction factor of bonding plane, to guarantee the fixing of pipe part bonding plane, this process can increase testing staff's workload greatly; Make and detect the cost rising, brought a lot of unnecessary loss to enterprise.
The utility model content
The utility model technical matters to be solved provides a kind of simple in structure, with low cost, time saving and energy saving and U-PVC pipe fitting load performance that satisfy testing requirements and detects anchor clamps.
For addressing the above problem, the described U-PVC pipe fitting of the utility model load performance detects anchor clamps, and it is characterized in that: it comprises pull bar, train wheel bridge, lower plate and anchor clamps; Said train wheel bridge and said lower plate link together through the symmetrically arranged said pull bar in two ends; The bottom of said train wheel bridge and the top of said lower plate are equipped with said anchor clamps, and pipe fitting is installed at this anchor clamps center; Be respectively equipped with rapid-acting coupling, vent valve mounting hole on the said train wheel bridge; One end of said anchor clamps links to each other with said rapid-acting coupling, vent valve respectively, and the bottom of this rapid-acting coupling and vent valve and said tube intracavity connect; The two ends up and down of said pipe fitting all connect sealing through said anchor clamps.
Said rapid-acting coupling and said vent valve are symmetrical set along the center line of said train wheel bridge.
Be respectively equipped with pressure ring, O-ring seal and the nut of screwing on the said anchor clamps; The said nut of screwing links together the two ends up and down and the said anchor clamps of said pipe fitting through said pressure ring, O-ring seal successively.
The utility model compared with prior art has the following advantages:
1, since in the utility model train wheel bridge and lower plate be fastened together through the symmetrically arranged pull bar in two ends, therefore, not yielding and intensity is high.
2, because the utility model anchor clamps are provided with O-ring seal, pressure ring, the nut of screwing, it cooperatively interacts and can significantly improve the anchor clamps sealing, guarantees the degree of accuracy that detects.
3, because the utility model cooperates through last lower plate and anchor clamps makes an experiment, therefore, need not carry out the polishing, cleaning, drying in early stage, bonding, dry run again, both simple to operate, time saving and energy saving again; Got rid of simultaneously because of bonding tubing breaks and caused the hidden danger of the failure of an experiment, improved the success ratio and the accuracy of test, guaranteed the promptness that detects, thus tracking instruction production better.
4, the utility model is simple in structure, with low cost.
