Abstract
The utility model relates to a tool for a leakage test of a corrugated tube, and belongs to the technical field of the tool for the leakage test of a mechanical sealing corrugated tube. The tool is composed of front and rear cover plates, a connecting bolt, sealing gaskets and a pressure test joint. The peripheries of the front and rear cover plates are provided with more than three through holes. The center of the rear cover plate is connected with the pressure test joint. The internal side of each of the front and rear cover plates is provided with one elastic sealing gasket for sealing effect respectively. The connecting bolt penetrates through the front and rear cover plates and the sealing gaskets so that the corrugated tube is fastened. The beneficial effects of the tool are that: the tool is simple and reasonable in structure, easy to process and simple and rapid in operation without any damage to the corrugated tube so that the tool is applicable to the leakage test of the corrugated tubes with various diameter sizes and high in practicality.
Description
Technical field:
The utility model relates to a kind of specific purpose tool of corrugated tube leak test, belongs to mechanical seal corrugated tube leak test technical field of tools.
Background technology:
Metal bellows mechanical seal belongs to the one of mechanical seal, for the sealing of the turning axle of machinery pump slewing.Being of wide application of it, from low temperature to high temperature, from neutral medium to Korrosionsmedium, from low speed to high speed, the condition of work from common to harsh all can be selected.In petrochemical industry, be generally used for important pump.As high temperature oil pump, liquid hydrocarbon pump etc.
Corrugated tube is the elastic compensating element of such mechanical seal, at pump continuously, play very important effect in safety in production process.Its material is generally austenitic stainless steel, and wall thickness only has 0.16～0.2mm.
Pump, in operational process, is in due to corrugated tube in the rugged surroundings such as high temperature, with pressure, vibration, corrosion for a long time, and corrugated tube usually can occur crackle at crest and trough place because of tired, even fracture; With pressure, the inflammable and explosive medium of high temperature will flow out from cracks, causes the leakage of pump, then may cause poisoning, fire and explosion accident.
Before mechanical seal maintenance, installing, generally all need it to check, and be observation method of naked eye to the corrugated tube inspection of mechanical seal conventionally, very easily find for obvious crackle, but for trickle crackle, naked eyes just cannot be checked through, and also there is no special inspection and testing tool.So leak as long as the bellows mechanical seal of pump, in order to guarantee to be perfectly safe reliably, often will change a whole set of mechanical seal, can, can also reusable, expensive bellows mechanical seal having eliminated, cause the very large waste of material unavoidably.Therefore, the corrugated tube leak test of special mechanical seal detects just particularly important, also imperative.
Summary of the invention:
The purpose of this utility model is the defect that cannot with the naked eye check corrugated tube fine cracks existing in prior art in order to overcome, provide one have simple in structure, practical, easy to operate, fast, corrugated tube leak test specific purpose tool accurately.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of corrugated tube leak test specific purpose tool, is made up of front shroud, back shroud, coupling bolt, has central through hole on back shroud, and the internal thread of its central through hole is connected with action pressure-testing joint, on the front shroud end face corresponding with back shroud, is lined with elastic sealing element.
The beneficial effects of the utility model are: simple and reasonable for structure, and handling ease; Simple to operate, quick, to corrugated tube without any damage; Be applicable to the corrugated tube leak test of various diameter, practical.
Accompanying drawing explanation:
Fig. 1 is the utility model structural front view.
Embodiment:
In conjunction with Fig. 1, the utility model is described in detail:
A kind of corrugated tube leak test specific purpose tool, formed by front shroud 7, back shroud 4, coupling bolt, on front shroud 7, have central through hole, its central through hole internal thread is connected with action pressure-testing joint 1, on front shroud 7 end face corresponding with back shroud 4, is lined with respectively front shroud elastic sealing element 5A and back shroud elastic sealing element 5B.
On the ring week of described front shroud 7 and back shroud 4, be evenly equipped with more than 3 through hole, for coupling bolt 2 is installed.
In the time carrying out leak test, corrugated tube 6 is placed between front shroud 7 and the corresponding end face of back shroud 4, adjust the nut 3 of coupling bolt, after achieving butt-end packing, form annular seal space, instrument entirety is put into water, in annular seal space, pass into compress wind by action pressure-testing joint, can realize the detection to corrugated tube performance.
