Abstract
The utility model relates to the pressure testing devices of bellows-welding component, more particularly to a kind of pressure test fixture of bellows component, including main body and channel, the mobile limit section of restricted bellows component is fixedly installed in main body one end, the mobile dismountable position limiting structure of restricted bellows component is arranged in the main body other end, the air inlet setting in channel is in limit section, the gas outlet in channel is arranged on the side of main body, so, dismountable position limiting structure one end insertion needs to detect bellows component in main body, after limit section one end is fixed, it is fixed by dismountable position limiting structure, it can be used to subsequent air-leakage test, the utility model structure is simple, bellows component can be quickly installed and carry out air-leakage test.
Description
Technical field
The utility model relates to the pressure testing devices of bellows-welding component, and in particular to a kind of pressure testing folder of bellows component
Tool.
Background technique
In the prior art, the air-leakage test of bellows component, therefore, one side helium matter are generally carried out using helium mass analyzer
Spectrometer is expensive, on the other hand, helium mass analyzer it is complicated for operation, for medium-sized and small enterprises, application cost is high.
For a kind of composite pressure testing tool of current bellows component, the fixture of bellows is two coaxial arrangements
Grip block, two grip block are relatively mounted on the inner wall of sink, and bellows component is sealedly connected between two grip blocks, such
Corrugated pipe clamp, which needs to install with the both ends of bellows component respectively during the installation process, to be fixed, and regular hour damage is caused
It loses, grip block is mounted on inboard wall of cistern and has a certain impact to grip block, and ripple can quickly be fixed by now needing to develop one kind
The fixture of pipe, ventilation can test the air-tightness of bellows into the water.
Utility model content
The purpose of this utility model is that: for current bellows component pressure test fixture is installed the fixed bellows component time
Longer problem provides a kind of pressure test fixture of bellows component.
To achieve the goals above, the technical solution adopted in the utility model are as follows:
Restricted wave is fixedly installed in a kind of pressure test fixture of bellows component, including main body and channel, described main body one end
The mobile position limiting structure of restricted bellows component, the limit is arranged in the mobile limit section of line tube assembly, the main body other end
Bit architecture is detachably arranged in the main body, and the channel inlet mouth setting is in limit section, the channel gas outlet setting
On the side of main body.
Further, the pressure test fixture of a kind of bellows component further includes two sealing rings, and the sealing ring setting exists
On the side of the main body, the gas outlet is arranged between two sealing rings, increases air-tightness during pressure testing.
Further, the position limiting structure is arranged on the body, and the nut limit using setting on the body,
The matched external thread structure of nut is provided in the main body, nut can be good at fastening journey needed for adjusting bellows component
Degree.
Further, the internal thread structure for cooperating quick connector is provided at the air inlet of the limit section, in this way, can
Cooperation quick connector well, realizes quick air inlet and pressure testing.
In conclusion due to the adoption of the above technical solution, the beneficial effect of the application is:
1. bellows component is put into main body limit section limit, separately by setting limit section and dismountable position limiting structure
One end is fixed with dismountable position limiting structure, can reduce the time that fixture installs fixed bellows component.
2. the pressure test fixture of the bellows component by above-mentioned setting can directly ventilate after installing bellows component,
It is then placed in water, can be detected the air-tightness of bellows component, shorten the time of detection bellows component air-tightness, improve
Production efficiency.
Detailed description of the invention

Fig. 2 is the structural schematic diagram that the utility model assembles bellows component；
Marked in the figure: 1- main body, the channel 2-, 3- limit section, 4- position limiting structure, 5- air inlet, the gas outlet 6-, the side 7-,
8- sealing ring, 9- bellows component, 10- bellows seal.
Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
As depicted in figs. 1 and 2, a kind of pressure test fixture of bellows component, including main body 1 and channel 2,1 one end of main body are solid
The mobile limit section 3 of restricted bellows component 9 is set surely, and the mobile limit of restricted bellows component 9 is arranged in 1 other end of main body
Bit architecture 4, removably on the body 1, the air inlet 5 in channel 2 is arranged in limit section 3 position limiting structure 4, channel 2 for setting
Gas outlet 6 is arranged on the side 7 of main body 1.
The pressure test fixture of this bellows component further includes two sealing rings 8, and sealing ring 8 is arranged on the side 7 of main body 1,
Gas outlet 5 is arranged between two sealing rings 8, and sealing ring 8 used in the present embodiment is O-ring seal, and 1 other end of main body is set
The mobile position limiting structure 4 of the limitation bellows component 9 set uses nut, is provided with the matched external thread structure of nut in main body 1,
Limit the internal thread structure being provided at the air inlet 5 of section 3 for cooperating quick connector.
The specific workflow of the utility model: removing the nut of the pressure test fixture of this bellows component, will remove nut
One end is inserted into bellows component 9 to be detected, and the bellows seal 10 of one end and main body 1 are fixed in bellows component 9,
And the movement of bellows component 9 is limited by limit section 3, O-ring seal 8 is used for seal bellows pedestal 10 and main body 1, ripple
The bellows seal 10 of the other end and main body 1 are fixed in tube assembly 9, and the shifting of bellows component 9 is limited by tightening nut
Dynamic, O-ring seal is used for seal bellows component 10 and main body 1, in the follow-up process, by the defeated of compressed air conveying device
Gas pipeline is inserted into quick connector, and the bellows component 9 and fixture that assemble are put into sink, is conveyed and is filled by compressed air
