Description
Technical field
The present invention relates to ship's space tightness test field, in particular to a kind of open type cabin air-leakage test test is used
Tooling and its application method.
Background technique
At present during shipbuilding, the close property in cabin is the project that must carry out submitting inspection.For airtightness cabin,
Such as the cabins such as cargo tank, water tank, manhole road door closure need to only be sealed, can directly be inflated by pipeline and carry out air-tight test.
And for open type cabin, such as side tugboat, hole capital after selling all securities etc., nobody duct door closure is isolated, but has size at 1 square metre or more
Large opening in this way before doing such cabin air-tight test, large opening must just be sealed as open channels region
It closes.Previous large opening closing is all to carry out butt welding weldering with four side steel plate of large opening using the sealing plate as bore size
It connects, to guarantee that the gas of air-tight test is not revealed from there, this method not only wastes material, also to be welded, and welds
Carbon afterwards digs repairing of cutting off and polish, and additional workload increases, and the air-tight test preparation time is longer.
Summary of the invention
To waste of material caused by large opening closing, work effect when in order to solve existing open type cabin air-leakage test
The low problem of rate, the object of the present invention is to provide a kind of open type cabin air-leakage test test tooling and its users
Method.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of open type cabin air-leakage test test tooling, including arch code, bolt and round tube, the arch code are 90 degree
The band steel of circular arc, the arch code have both ends, and one of end is weldingly fixed on the round tube outer surface；The round tube is
The cylindrical round steel of disposed thread, the screw thread on the bolt match with the screw thread inside the round tube.
Specifically, the band steel of the arch code is with a thickness of 4mm-8mm.
Specifically, the arch code is fixed with the round tube using fillet welding, the height of leg is 3mm.
Specifically, the bolt performance rate is 4.8 grades.
Specifically, the bolt outer diameter is 16mm, the round tube outer diameter is 21.3mm.
Specifically, the bolt is in contact with the round tube, the reach s at position is at least 50mm.
A kind of open type cabin air-leakage test test application method of tooling,
Firstly, a sealing plate of selection length and width dimensions out 10mm more major than four edge lengths of cabin large opening, is covered on described
Cabin large opening surrounding；
Secondly, according to the length and width dimensions of the sealing plate, it is unilateral to place a tooling ontology every 300mm；
Again, the arch code of each tooling ontology is scheduled into four side of cabin large opening far from the end point solid welding of the round tube
On the steel plate at place, the bolt on the tooling ontology is rotated down, until sealing plate four while with cabin large opening four steel plate
Until closely connected；
Finally, if there is gas leakage at the large opening of cabin, adjusting bolt when being inflated to cabin air-tight test and continuing to backspin
Turn, until there is no gas leakages.
Compared with prior art, the present invention realize the utility model has the advantages that tooling of the invention, by by arch code far from round tube
End point solid welding on the four side steel plate of cabin large opening, the height for adjusting bolt can be realized to cabin large opening steel plate
The adjusting of tightness between sealing plate, the configuration of the present invention is simple is easy to use, reduces the waste of material in use process, improves
Working efficiency.

Specific embodiment
Below according to attached drawing, the present invention will be described in detail.
Reference attached drawing 1,
A kind of open type cabin air-leakage test test tooling, including arch code 10, bolt 20 and round tube 30, the arch code
10 be the band steel of 90 degree of circular arcs, and the arch code 10 has both ends, and one of end is weldingly fixed on 30 outer surface of round tube
On；The round tube 30 is the cylindrical round steel of disposed thread, the spiral shell inside screw thread and the round tube 30 on the bolt 20
Line matches.
The band steel of the arch code 10 is with a thickness of 4mm-8mm.
The arch code 10 is fixed with the round tube 30 using fillet welding, and the height of leg is 3mm.
20 performance rate of bolt is 4.8 grades.
20 outer diameter of bolt is 16mm, and 30 outer diameter of round tube is 21.3mm.
Be in contact with the round tube 30 reach s at position of the bolt 20 is at least 50mm.
Referring to attached drawing 2 and attached drawing 3
A kind of open type cabin air-leakage test test application method of tooling,
Firstly, a sealing plate 2 of selection length and width dimensions out 10mm more major than 3 four edge lengths of cabin large opening, is covered on institute
State 3 surrounding of cabin large opening；
Secondly, according to the length and width dimensions of the sealing plate 2, it is unilateral to place a tooling ontology 1 every 300mm；
Again, the arch code of each tooling ontology 1 is scheduled into cabin large opening 3 four far from the end point solid welding of the round tube
On steel plate where side, the bolt on the tooling ontology 1 is rotated down, until sealing plate 2 four is while with cabin large opening four
Until steel plate 4 is closely connected；
Finally, if there is gas leakage at cabin large opening 3, adjusting bolt 20 in the inflation of cabin air-tight test and continuing downwards
Rotation, until there is no gas leakages.
