Comprehensive test device for joint sealing and hydraulic circulating of pipe body

Abstract

The invention discloses a comprehensive test device for joint sealing and hydraulic circulating of a pipe body, and belongs to the field of pipe body detection equipment. The comprehensive test device specifically comprises a square base, wherein a front baffle wall and a rear baffle wall are fixedly arranged at the two ends of the base; the front baffle wall is connected with the rear baffle wall through a pull rod; a pushing hydraulic cylinder is arranged in the middle of the front baffle wall; a movable end plug is mounted at the extension end of the pushing hydraulic cylinder; a press-down mechanism and a deflection hydraulic cylinder are arranged in the middle of the base; and the press-down mechanism and the deflection hydraulic cylinder are arranged between the front baffle wall and the rear baffle wall. The comprehensive test device can be used for carrying out joint sealing detection and hydraulic circulating tests on a nodular cast iron pipe at the same time, so that the defect of one device for one test is avoided, the utilization rate of the equipment is increased and the convenience is provided for staffs in operation.

Description

technical field [0001] The invention relates to a comprehensive experimental device for joint sealing and hydraulic circulation of ductile iron pipes, which belongs to the field of pipe body detection equipment. Background technique [0002] Today, with the continuous emergence of new technologies and materials, ductile iron pipes are pipes that cannot be completely replaced by other new materials, and still occupy an important position in the fields of water supply and gas transmission engineering. [0003] Before the 1980s in my country, the pressure pipes used in water supply projects were mainly steel pipes, socket cast iron pipes, reinforced concrete pipes and other pipes. Since then, the centrifugal ductile iron pipe industry has developed very rapidly. In particular, its mechanical properties are almost the same as those of steel pipes, or even higher, and its tensile strength is higher than that of asbestos cement pipes, polyethylene pipes, glass fiber reinforced pip...

AI Technical Summary

Problems solved by technology

At present, there are many experimental tests required for ductile iron pipes, and most of the experimental devices are separated, that is, one test and one device, which not only reduces the utilization rate of equipment but also takes up a lot of space

At the same time, it cannot adapt to new test requirements, such as the hydraulic cycle test described in the document "Research on the Performance of Water-based Epoxy Cover Layer Lined with Ductile Iron Pipe Cement Mortar", etc.
