Abstract
The utility model discloses a sealing head used for the tests of plastic pipe pressure-withstanding and explosion, which includes a clamping disc, a pressing ring, a sealing ring, and a clamping core provided with a channel; the pressing ring takes the shape of a sidestep and is sleeved and arranged on the clamping core; the end of the pressing ring is provided with a trimming; a concave trough can be formed between the trimming and the pressing disc at the end of the clamping core; the concave trough is provided with a sealing ring; the diameter of the front section of the pressing ring complies with the diameter of the pressing disc and is slightly less than the internal diameter of the specimen; after the pressing ring and the clamping core are arranged in the internal wall of the specimen, the axial move between the pressing ring and the clamping core can make the sealing ring in the concave trough extrude and deform and tightly glue to the internal wall of the specimen so as to implement the sealing; the utility model has good adaptability to the internal diameter tolerance of the tested specimen, insures good sealing to the port of the specimen, and has the advantages of smart usage, good sealing performance and convenient disassembly and assembly, etc.
Description
Technical field:
The utility model relates to a kind of test top pressure closure, relates to particularly that a kind of plastic pipes fitting is withstand voltage, the explosion bulge test top pressure closure.
Background technology:
Continuous expansion along with the plastic applications scope, its demand is increasing, corresponding manufacturer also increases thereupon, the tubing model of being produced, specification is of a great variety, country has formulated corresponding standard, pilot project to plastic pipe, require all to have done concrete regulation, and plastic pipe is withstand voltage, explosion bulge test is absolutely necessary, carry out withstand voltage to plastic pipe at present, the anchor clamps that explosion bulge test is used, what adopt is outer close equipment structure, and only be applicable to tubing and pipe fitting with nominal outer diameter, then inapplicable for the tubing and the irregular goods of appearance that with the internal diameter are standard, this has brought inconvenience for manufacturing enterprise and detection department.
Summary of the invention:
The utility model is at the deficiencies in the prior art, provide a kind of plastic pipes fitting withstand voltage, the explosion bulge test top pressure closure, technical matters to be solved is applied widely, good sealing effect, and mounting or dismounting are convenient, can be used for being that the pipe part and the irregular goods of appearance of standard carry out withstand voltage with the internal diameter, explosion bulge test, the technical scheme that the utility model adopted is as follows: the utility model comprises chuck, trim ring and O-ring seal, it is characterized in that also comprising the sandwich 5 that is provided with runner 6, trim ring 2 is step-like, be sleeved on the sandwich 5, and can move axially with respect to the sandwich generation, the termination of trim ring is provided with side cut, can form groove between the platen 10 of this side cut and sandwich termination, groove is established " O " RunddichtringO 3, the diameter of trim ring leading portion is consistent with the diameter of platen, and be slightly less than the internal diameter of test specimen, the trim ring back segment plays the role of positioning, and one side contacts with chuck, and one side contacts with test specimen.
For the enhanced leaktightness effect, also can between sandwich, establish " O " RunddichtringO 4 at trim ring.
Moving axially between above-mentioned trim ring and the sandwich can be adopted following three kinds of schemes:
The one, between trim ring and sandwich, adopt threaded engagement, make to produce between trim ring and the sandwich by the turn trim ring and move, can push " O " O-ring seal 3.
The 2nd, at the other end of sandwich screw thread is set, make to produce between trim ring and the sandwich by clamp nut 8 and move, realize the purpose of extruding " O " O-ring seal 3.
The 3rd, the threaded hole that is communicated with trim ring and platen is set, make to produce between trim ring and the sandwich by trip bolt 9 and move, thus extruding " O " O-ring seal 3.
Action principle of the present utility model is as follows: at first trim ring, the sandwich that is nested together placed in the test specimen, make between trim ring and the sandwich to produce by external force and move axially, make the be squeezed distortion and being close on the test specimen inwall of O-ring seal in the groove between trim ring termination and the platen, at this moment, the test specimen termination withstands on the step of trim ring, finish seal operation, be fixed on the examination frame by the test specimen of chuck at last good seal.
Compared with prior art, the utility model is good to the adaptability of the id tolerance of tested sample, can guarantee the excellent sealing to sample port, has advantages such as use is flexible, good seal performance, mounting or dismounting convenience.
