Description
Technical Field
The utility model relates to an experiment frock, concretely relates to compound pipe hydrostatic test frock for pipe fitting of steel skeleton polyethylene belongs to plastic conduit experiment technical field.
Background
The large-caliber plastic pipe belongs to a chemical building material, is a replacement product for replacing steel by plastic and replacing cement by plastic, is applied to municipal drainage, remote low-pressure water delivery, farmland irrigation and the like, and has important significance for energy conservation, emission reduction and environmental protection. The steel skeleton plastic composite pipe is used as a novel pipeline, and solves the difficult problems of pressure resistance and corrosion resistance of metal pipelines and plastic pipelines. Before the steel skeleton pipe fitting is used, a pressure test needs to be carried out to determine the maximum pressure which can be borne by the steel skeleton pipe fitting in the using process.
At present, the hydrostatic test tool for the steel skeleton polyethylene plastic composite pipe fitting used in a laboratory is simple in structure and only comprises a common blind plate and a skeleton gasket. The rubber material that the skeleton packing ring on the market used at present is harder, and rubber is not good to skeleton steel ring cladding effect, and the packing ring is out of shape and the fracture easily, and is great to the experimental result influence, thereby causes the pressure to keep not to lead to the test failure even, perhaps the serious condition that the packing ring directly deviate from. In view of the above circumstances, it is very necessary to develop a novel pressure test tool for steel skeleton polyethylene plastic composite pipe fittings.
The test tool is convenient to install during testing, so that the test period is greatly shortened; use novel frock, greatly increased the success rate of experiment.
Disclosure of Invention
The utility model aims at overcoming current frock technique shortcoming of suppressing, to steel skeleton polyethylene plastic composite pipe fitting suppress experimental, provide a suppress experimental frock.
The technical scheme of the utility model is realized like this: the hydrostatic test tool for the framework polyethylene plastic composite pipe fitting comprises a blind plate, a fastener, an annular rubber ring and a bolt for fixing the fastener.
The blind plate is provided with a rubber ring groove for placing a rubber ring, and the edge of the rubber ring groove is provided with a chamfer; the purpose is as follows: the annular rubber ring can expand transversely after being extruded, and the chamfer prevents sharp rubber ring groove edge from cutting the annular rubber ring, and leads to the rubber ring to release and break because of stress concentration. The blind plate is provided with bolt holes for mounting fasteners and water inlet/outlet holes.
The outer edge of the fastener is provided with a certain radian and is matched with the inner wall of the steel skeleton polyethylene plastic composite pipe fitting to be tested; the outer edge of the fastener is provided with a chamfer angle; the fasteners are mounted to the blind plate using bolts. The purpose of the fastener is as follows: 1. the steel skeleton polyethylene plastic composite pipe fitting is convenient to mount; 2. the position of the steel skeleton polyethylene plastic composite pipe fitting is limited, so that the pipe fitting and the annular rubber ring are not dislocated due to the deviation of the pipe fitting caused by external force or gravity.
The utility model discloses outstanding advantage is: the defect that the existing test tool is wrong is solved: the sealing performance of the tool is poor, the framework gasket is easy to damage, the tool is troublesome to install, and the framework gasket and the pipe fitting are easy to misplace to cause water leakage and the like. The tool is simpler and more convenient to mount, the sealing performance is better, the success rate of the test is improved, and the test time is saved.

Detailed Description
The present invention will be further described with reference to the following examples.
As shown in fig. 1, 2, 3 and 4, the hydrostatic test tool for the steel skeleton polyethylene plastic composite pipe fitting comprises a blind plate 1, a fastener 2 and an annular rubber ring 3. The blind plate 1 is provided with bolt holes 22 for mounting fasteners 2, a rubber ring groove 13 for placing an annular rubber ring 3 and water inlet/outlet holes 14; the edge of the rubber ring groove 13 is provided with a chamfer 131.
The outer edge of the fastener 2 is provided with a chamfer 21 which is convenient for the installation of the steel skeleton polyethylene plastic composite pipe fitting; two through bolt holes 22 are provided on the fastener 2. Preferably, the height of the fastener is 40mm, the thickness of the fastener is 30mm, and the included angle between the left end face and the right end face is 30 degrees. Preferably, the bolt hole diameter of the fastener is 5mm, and the bolt for mounting the fastener is an M5 bolt.
The cross section of the annular rubber ring 3 is circular, and the diameter is 10-15 mm. Preferably, the circular diameter of the cross section of the annular rubber ring is 10 mm.
Compared with the prior art, the scheme has the advantages that: the defect that the existing test tool is wrong is solved: the sealing performance of the tool is poor, the framework gasket is easy to damage, the tool is troublesome to install, and the framework gasket and the pipe fitting are easy to misplace to cause water leakage and the like. The tool is simpler and more convenient to mount, the sealing performance is better, the success rate of the test is improved, and the test time is saved.
The above description is only provided as an implementable technical solution of the hydrostatic test tool for the steel skeleton polyethylene plastic composite pipe fitting of the present invention, and is not provided as a single limitation condition for the structure itself.
