Description
Technical field
The utility model is related to a kind of stable Air-tight Test sealing device of performance.
Background technology
, it is necessary to close pipeline section to be detected, Ran Houxiang during the sealing detection of pipeline Air-tight Test or tank body is carried out
Inflated in pipeline section to be detected（The sealing detection of tank body can abstract be to carry out sealing detection to one section of pipeline section）, by air gauge come
Detect the gas-tight property of pipeline section.Because the use high pressure gas in experimentation of holding one's breath is inflated supercharging to inner tube segment, its air pressure
Control range have certain fluctuation, if the connection between sealing device and pipeline is not sufficiently stable, it will cause sealing device
Displacement extrudes pipeline by high pressure, causes test failure.Lack a kind of easy to use in the market, sealing property is stable to close
Gas tests sealing device.
The content of the invention
The purpose of this utility model is to overcome the defect of prior art to be sealed there is provided a kind of stable Air-tight Test of performance
Device, its stable connection between pipeline, and it is easy to use.
To achieve the above object, the utility model employs following technical scheme：
A kind of stable Air-tight Test sealing device of performance, including be separately positioned on two of pipeline section A1 two ends to be tested it is close
Air bag 1 is sealed, two pressure bladders 1 can treat test section A1 and be sealed, an annular seal space is formed between two pressure bladders 1
2, the pressure of pressure in the air supply pipe 3 of supply in oriented annular seal space 2 and measurement annular seal space 2 is set on one of pressure bladder 1
Power table 4；
One end of pressure bladder 1 sets the air inlet 11 of inflation in oriented pressure bladder 1, and air inlet 11 is towards annular seal space 2
It is outside；The hangnail 5 of quality of rubber materials, hangnail 5 are arranged side by side on the side wall that pressure bladder 1 is connected with pipeline section A1 tube walls to be tested
To the outer inclination of annular seal space 2, angle of inclination is β, and β is more than or equal to 15 degree, less than or equal to 30 degree.
The utility model is integrally easy to use, can effectively treat test section A1 and be sealed, pressure bladder 1 is tried with waiting
Pipeline section A1 stable connections are tested, voltage endurance capability is strong.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the D portions mplifying structure schematic diagram of accompanying drawing 1.
In the accompanying drawings, 1 pressure bladder, 11 air inlets, 2 annular seal spaces, 3 air supply pipes, 4 pressure gauges, 5 hangnails, A1 pipes to be tested
Section, 6 draw rings, 7 pull ropes.
Embodiment
The embodiment provided below in conjunction with accompanying drawing 1 to 2, further illustrates embodiment of the present utility model.This reality
The following description is not limited to new.
As shown in Figure 1-2：A kind of stable Air-tight Test sealing device of performance, including it is separately positioned on pipeline section A1 to be tested
Two pressure bladders 1 at two ends, two pressure bladders 1 can treat test section A1 and be sealed, shape between two pressure bladders 1
Into an annular seal space 2, the air supply pipe 3 of supply and measurement annular seal space in oriented annular seal space 2 are set on one of pressure bladder 1
The pressure gauge 4 of pressure in 2；The width at the two ends of pressure bladder 1 is less than the width at middle part, be conducive to air pressure in pressure bladder 1 to
Middle part is concentrated, and improves the connective stability between the side wall and pipeline section A1 to be tested of pressure bladder 1, and this " middle part is big by two
It is small " structure be easy to pressure bladder 1 to be installed into pipeline section A1 to be tested.Only need to connect air supply pipe 3 and high-pressure air source when using
Connect.
One end of pressure bladder 1 sets the air inlet 11 of inflation in oriented pressure bladder 1, and air inlet 11 is towards annular seal space 2
It is outside；The hangnail 5 of quality of rubber materials, hangnail 5 are arranged side by side on the side wall that pressure bladder 1 is connected with pipeline section A1 tube walls to be tested
To the outer inclination of annular seal space 2, angle of inclination is β, and β is more than or equal to 15 degree, less than or equal to 30 degree, and hangnail 5 is to the outside side of annular seal space 2
To inclination so that after pressure bladder 1 is put into pipeline section A1 to be tested and inflated, hangnail 5, which is grabbed, to be attached on pipeline section A1 to be tested tube wall,
The connective stability between pipeline section A1 to be tested of whole pressure bladder 1 is improved, the anti-pressure ability of whole sealing device is improved.
It is preferred that, pressure bladder 1 is fixed with traction towards being provided with draw ring 6, draw ring 6 on one end outside annular seal space 2
Rope 7,, can be by drawing after experiment is finished when there is certain distance at pipeline section A1 to be measured two ends apart from the mouth of pipe of whole pipeline
Drag pull rope 7 to take out pressure bladder 1, further increase the dismounting speed of whole device, improve property easy to use.
The utility model is integrally easy to use, can effectively treat test section A1 and be sealed, pressure bladder 1 is tried with waiting
Pipeline section A1 stable connections are tested, voltage endurance capability is strong.Volume Changes are big after being inflated due to pressure bladder 1, so a kind of sealing of model
Device is applicable to the use with multiple diameter pipeline and tank body.
In use, it is that it is very convenient on pipeline to be installed to without gaseity that pressure bladder 1, which is installed preceding,.During experiment, inflation is realized
Sealing.After the completion of experiment, directly deflate, greatly improve disassembly efficiency.
In addition, because most of test sites in place out of doors, it is necessary to carry, pressure bladder 1 is lightweight, volume
It is small, it can effectively improve use, the conevying efficiency of testing crew.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to protection domain of the present utility model.
