The processing step that uses the utility model to detect the water-fast impact of fluted tube is:
With being connected in the punching oil pipe port after given the test agent (fluted tube) water filling, carry out exhaust to given the test agent, the opening pressure test pump is given the water tank exhaust, and Adjustment System pressure is 2.5Mpa then; When the right side of reversal valve coil gets when electric, water pressure impact test piece, reversal valve left side coil get when electric, and pipeline carries out pressure release; The PLC control system is counted synchronously, system's auto stop behind the circulation impact given the test agent 20000 times.
Whether reach requirement by GB inspection given the test agent.
Above embodiment only is used to explain the technical scheme of the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to preferred embodiment; The those of ordinary skill in affiliated field is to be understood that; Still can make amendment and perhaps the part technical characterictic is equal to replacement the embodiment of the utility model; And not breaking away from the spirit of the utility model technical scheme, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
