Description
Technical field
The present invention relates to tubing air-leakage test field, refer in particular to a kind of pipe connector air-leakage test assembly.
Background technology
Pipe connector air tightness detection equipment is mainly used to detect whether the interface position of pipe fitting leaks gas, owing to pipeline is usual
It is used for carrying various gas (including poisonous, to have pollution gas) or various liquid (including poisonous, to have pollution liquid), and
All there is the interface position at pipe fitting in most of pipe leakage, so, the air-leakage test of pipe connector is the most particularly significant, thus
The purposes of pipeline air tightness detection machine is the most widely；But the at present air-leakage test to pipe connector, mainly use by
Pipeline two is blocked, and will detect, this check system in pipeline after filling high pressure gas in pipeline encroached water or in foaming agent
Operation complexity, the detection time is longer, so that the work efficiency that duct products produces is low.
Accordingly, it is desirable to provide a kind of simple operation, the pipe connector air-leakage test assembly that detection efficiency is high, this assembly is not
Be only capable of precision detects whether there is gas leakage at pipe connector, and easy to detect, substantially increases the inspection of duct products
Survey efficiency.
Summary of the invention
It is an object of the invention to provide a kind of simple operation, the pipe connector air-leakage test assembly that detection efficiency is high, be somebody's turn to do

The detection efficiency of product.
The pipe connector air-leakage test assembly of the present invention, including the mandrel that can be inserted in detected pipe connector and two
Interval is coated at the elastic seal ring outside described mandrel；Described mandrel one end is provided with air inlet, and mandrel is positioned at two elastic seal rings
Between sidewall be provided with the gas outlet connected with described air inlet；Described mandrel is provided with for described elastic seal ring vertically
Being located remotely from each other and carry out spacing locating part, elastic seal ring described in two can be at the work of the compressed gas discharged from described gas outlet
Seal for pipe joints between being radially expanded two sealing rings under with；
Further, the axial both sides of two elastic seal rings are all arranged with outer back-up ring and inner shield ring, and described outer back-up ring is for right
Elastic seal ring is located remotely from each other and carries out spacing, and described inner shield ring can be under the effect of the compressed gas discharged from described gas outlet
Axially compressed described elastic seal ring；
Further, the described the most integrally formed restraining position ring block of mandrel cylindrical, the outer back-up ring near described spacing ring passes through
The mode offseted with described spacing ring end face realizes axial limiting, away from the outer back-up ring of described spacing ring by being fixedly welded on core
Axle cylindrical；
Further, outside mandrel between elastic seal ring described in two, it is cased with sleeve, and elastic to two by this sleeve
Sealing ring is the most close to each other carry out spacing；
Further, the inner circle of described sealing ring is circumferentially arranged with annular groove, and the bottom land of described annular groove is arc surface；
Further, described sleeve lateral wall is provided with the steam vent corresponding with described gas outlet；
Further, described air inlet is connected by the air flue being axially disposed in mandrel with gas outlet；
Further, described air flue is provided with female thread near the sections of air inlet.
The invention has the beneficial effects as follows: the pipe connector air-leakage test assembly of the present invention, pipe connector is being carried out gas
Close property detection time, first by this assembly insert need detection tubing in, and make two elastic seal rings between pipe connector, so
Air inlet on backward mandrel pours gases at high pressure, and gases at high pressure will pour between two elastic seal rings after gas outlet is discharged
In inner cavity of pipe, the pressure of gases at high pressure, by axially compressed two elastic seal rings, makes elastic seal ring be radially expanded and presses
Tight at tubing inner headed face, make tubing inner chamber realize sealing, now, if there is no gap or micropore at tube connector, the gas in tubing
Pressure will keep high value, if tube surfaces or joint exist gap or micropore, the air pressure in tubing will be gradually lowered, and therefore lead to
Cross existing barometer to be maybe immersed in the water by detected pipe fitting and i.e. can detect that tubing air-tightness is the best.
Accompanying drawing explanation
With embodiment, technical solution of the present invention is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is the axonometric drawing of the present invention.
Detailed description of the invention
Fig. 1 is the axonometric drawing of the present invention；As it can be seen, the pipe connector air-leakage test assembly of the present embodiment, including can
Insert the mandrel 5 in detected pipe connector and at least two interval is coated at the elastic seal ring 2 outside described mandrel 5；Described
Mandrel 5 one end is provided with air inlet 8, and the mandrel 5 sidewall between two elastic seal rings 2 is provided with and connects with described air inlet 8
Gas outlet 4；Described mandrel 5 is provided with and carries out spacing locating part, described in two for being axially away from one another two elastic seal rings 2
Elastic seal ring 2 can be radially expanded under the effect of the compressed gas discharged by described gas outlet 4 and be sealed by tubing, right
When tubing carries out air-leakage test, first this assembly is inserted in the tubing needing detection, and make two elastic seal rings 2 be positioned at needs
Between the pipe joint of detection, then the air inlet 8 on mandrel 5 pours gases at high pressure, and gases at high pressure will after gas outlet 4 is discharged
Pouring in the inner cavity of pipe between two elastic seal rings 2, the pressure of gases at high pressure, by axially compressed two elastic seal rings 2, makes
Elastic seal ring 2 is radially expanded and is pressed on tubing inner headed face, make tubing inner chamber realize seal, now, if tube surfaces or
Joint does not has gap or micropore, and the air pressure in tubing will keep high value, if tube surfaces or joint exist gap or micro-
Hole, the air pressure in tubing will be gradually lowered, and therefore maybe by existing barometer detected pipe fitting is immersed in the water and can be detected
Go out tubing air-tightness the best.
In the present embodiment, the axial both sides of elastic seal ring 2 described in two are all arranged with outer back-up ring 1 and inner shield ring 3, described outside
