Abstract
The utility model discloses a kind of air-tightness auxiliary detection devices for pressure vessel, apply in air seal test apparatus field, including body and the connector for being arranged on its one end；The body is provided in the axial direction with shrinkage pool in one end away from connector；The inner surface of the shrinkage pool and the outer surface of connector are equipped with screw thread；The connector and body interior are axially through offering the venthole that is connected with shrinkage pool.It is to open two holes on component to be measured unidirectionally to be detected mainly to solve existing airtight test method, hole air inlet, outlet air at one.There are the problem of for the number of openings it is more, during pressurization air pressure it is unstable, it is necessary to ensure the pressure holding effect of multiple tappings, accuracy is relatively low, and need after testing to do encapsulation process to multiple perforates, it is less efficient.It only needs to open up a hole on component to be measured when the utility model is used, the good pressure maintained in the components such as babinet, tank body makes test more accurate, rapidly.
Description
Technical field
The utility model belongs to air seal test apparatus field, and in particular to a kind of air-tightness for pressure vessel aids in inspection
Survey device.
Background technology
In the large-scale component of the industries such as ship, heavy industry, as babinet, tank body construction in, it is necessary to carry out airtight examination to component
It tests.Existing airtight test method is to open two holes on component to be measured unidirectionally to be detected, hole air inlet, outlet air at one.It deposits
The problem of it is more for the number of openings, air pressure is unstable, it is necessary to ensure the pressure holding effect of multiple tappings during pressurization, accuracy compared with
It is low, and need after testing to do encapsulation process to multiple perforates, it is less efficient.
Therefore, it is necessary to work out a kind of air-tightness auxiliary detection device for pressure vessel, ensure only to need when using
A hole is opened up on component to be measured, the good pressure maintained in the components such as babinet, tank body makes subject to test more
Really, rapidly.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of air-tightness auxiliary detection dresses for pressure vessel
It puts, ensures only to need to open up a hole in member bodies to be measured when using, in the components such as good maintenance babinet, tank body
Pressure, make test more accurate, rapidly.
In order to achieve the above objectives, the utility model provides following technical solution：
A kind of air-tightness auxiliary detection device for pressure vessel, including body and the connector for being arranged on its one end；
The body is provided in the axial direction with shrinkage pool in one end away from connector；The inner surface of the shrinkage pool and the outer surface of connector are equal
Equipped with screw thread；The connector and body interior are axially through offering the venthole that is connected with shrinkage pool.
Preferably, the connection mode between the body and connector is integrally formed.
Preferably, the diameter of the body is no more than 50mm, of length no more than 200mm.
Preferably, the material of the body is Q235B steel.
Preferably, the internal diameter of the venthole is no more than 14mm, and less than the internal diameter of shrinkage pool.
Preferably, the diameter of the connector is less than the diameter of body.
Preferably, the diameter of the connector and the internal diameter of shrinkage pool are identical.
The beneficial effects of the utility model are：
1st, compared with prior art, only need to open up a hole can be completed test to the utility model on component to be measured, protect
It presses effect good, makes test more accurate, rapid.
2nd, the utility model body diameter is no more than 50mm, and of length no more than 200mm, itself size is small, easy to use,
It can carry.
3rd, the utility model connector diameter is less than body diameter, therefore incision pore size is small, after the completion of test, Ke Yizhi
The stifled eye of welding is connect, after can also being bolted with screw rod, welds, polish.
Description of the drawings
In order to make the purpose of this utility model, technical solution and advantageous effect clearer, the utility model provides as follows
Attached drawing illustrates：
Fig. 1 is the sectional view of the utility model front view；
Fig. 2 is the utility model front view.
It is marked in attached drawing as follows：Body 1, connector 2, shrinkage pool 3, screw thread 4, venthole 5.
Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
A kind of air-tightness auxiliary detection device for pressure vessel, including body 1 and the connector for being arranged on its one end
2；The body 1 is provided in the axial direction with shrinkage pool 3 in one end away from connector 2；The inner surface of the shrinkage pool 3 and connector 1
Outer surface is equipped with screw thread 4；The connector 1 and body 2 axially inside run through the venthole 5 for offering and being connected with shrinkage pool 3.
Further, the connection mode between the present embodiment uses body 1 and connector 2 is integrally formed.
Further, a diameter of 50mm, length 200mm for the body 1 that the present embodiment uses.
Further, the material for the body 1 that the present embodiment uses is made for Q235B steel by machining means, into
Type is easy.
Further, the internal diameter for the venthole 5 that the present embodiment uses is 14mm, and is less than the internal diameter of shrinkage pool 3.
Further, the diameter for the connector 2 that the present embodiment uses is less than the diameter of body 1.
Further, the diameter for the connector 2 that the present embodiment uses is identical with the internal diameter of shrinkage pool 3, is all 27mm.
Service condition：Air-tight test test start when, opened on component to be measured and 2 outer surface thread of connector 4
Then connector 2 is tightened on component to be measured by the threaded hole matched somebody with somebody.To increase air-tightness, can increase between connector 2 and component to be measured
