Abstract
nullA kind of leakproof measurement apparatus，It it is local weld seam standby and Ship Structure to the sea frock method that carries out tightness test，It is characterized in that: in and Ship Structure confined space standby in sea frock，The docking of local、When corner connection weld seam and end seam need tightness test，Rubber peel by vacuum tank and bottom is firm with the steel sticking with weld seam，By the T-shape hollow circular-tube on case top by evacuating air in case，Keep negative pressure certain time in vacuum tank，If manometric negative pressure numeral is constant, show that tightness of welding lines is good，If pressure changes, show that weld seam is defective，It provides the benefit that: need not again do tightness test and verify the quality of local weld seam in whole cabin after making the defective Weld Seam Repairation of weld seam in big cabin and local，Only need to be by this test method，Save a large amount of manpower、Material resources and time，And make local weld seam inspection more convenient.
Description
Technical field
A kind of leakproof measurement apparatus relates to standby and Ship Structure the local weld seam of sea frock and carries out tightness test device
Technical field,
Background technology
Sea frock is standby and the prior art of the tightness of welding lines test of Ship Structure has a following shortcoming:
1, find after the weld seam in cabin is detected a flaw or made film that quality problems need to reprocess, local weld seam needs after reprocessing
Doing tightness test, the device that prior art is taked is that the air seal test doing whole cabin is to check its local weld seam
Close property.
2, the docking of local in cabin, corner connection weld seam and end seam, if welding after the entirety air seal test of cabin, only
Need the weld seam of the last welding of detection, but prior art is that the air seal test doing whole cabin is to check it
The close property of weld seam.
If 3 standby and boats and ships the partial structurtes of sea frock are more transformed into welding job again, now it is also required to its weld seam
Carry out tightness test, but prior art still does the air seal test in whole cabin to check its close property.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides that a kind of sea frock is standby and Ship Structure local
The tightness test device of weld seam, technical scheme is as follows:
In and Ship Structure confined space standby in sea frock, the docking of local, corner connection weld seam and end seam need close property
During test, the rubber peel by vacuum tank and bottom is firm with the steel sticking with weld seam.By " T " on case top
Type hollow circular-tube, by evacuating air in case, keeps negative pressure certain time in vacuum tank, if manometric negative pressure number
Word is constant, shows that tightness of welding lines is good, if pressure change, shows that weld seam is defective.
The invention has the beneficial effects as follows: need not whole cabin after making the defective Weld Seam Repairation of the weld seam in big cabin and local
Room is again done tightness test and is verified the quality of local weld seam, only need to save big with this assay device
Amount human and material resources and time, and make the inspection of the weld seam of local more convenient.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the present invention, the steel plate in figure 1, with weld seam；2 vacuum tanks；3, rubber peel；
4, T-shape hollow circular-tube；5, air；6, Pressure gauge.
Detailed description of the invention
The present invention is further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present invention solves that sea frock is standby and the tightness test of locally weld seam in Ship Structure cabin,
It is characterized in that: in and Ship Structure confined space standby in sea frock, the docking of local, corner connection weld seam and end seam
When needing tightness test, the rubber peel by vacuum tank and bottom is firm with the steel sticking with weld seam.Pass through
The T-shape hollow circular-tube on case top, by evacuating air in case, keeps negative pressure certain time in vacuum tank, if pressure
The negative pressure numeral of table is constant, shows that tightness of welding lines is good, if pressure change, shows that weld seam is defective.
Vacuum tank lucite is made, and should be able to cover the weld seam needing to do tightness test, and case top arranges one
Block Pressure gauge, bottom is provided with one piece of rubber peel, should the steel plate with bottom with weld seam fasten with glue firm,
Middle, case top arranges a T-shape hollow circular-tube, and including transverse tube and vertical tube, vertical tube is connected with case top, horizontal
Guan Zeyu vertical tube connects, and fans the air to transverse tube one end gas with air pump, air from another section of transverse tube out, vacuum
Pressure is caused to increase, owing to vacuum tank external and internal pressure is poor, in case due to the air rapid flow on transverse tube in case
Air is flowed out by T-shape hollow circular-tube, until being evacuated.
If running into angle welding, it is polygonal casing that the vacuum tank used by apparatus of the present invention should be transformed into cross section,
And angle welding must be covered, the rubber peel of bottom should be with bottom and two block plate firm pastings of corner connection.
Claims (2)
1. a leakproof measurement apparatus, is that local weld seam standby and Ship Structure to sea frock carries out tightness test
Device, is characterized in that: in and Ship Structure confined space standby in sea frock, the docking of local, corner connection
When weld seam and end seam need tightness test, the rubber peel by vacuum tank and bottom and the steel plate with weld seam
It is firm to paste.By the T-shape hollow circular-tube on case top by evacuating air in case, in keeping vacuum tank
Negative pressure certain time, if manometric negative pressure numeral is constant, show that tightness of welding lines is good, if pressure becomes
Change and then show that weld seam is defective.
2. kind leakproof measurement apparatus as claimed in claim 1, vacuum tank lucite is made, should be able to
Covering the weld seam needing to do tightness test, case top arranges one piece of Pressure gauge, and bottom is provided with one piece of rubber peel,
Should fasten with glue firm by the steel plate with bottom with weld seam, middle, case top arranges one " T "
Type hollow circular-tube, including transverse tube and vertical tube, vertical tube is connected with case top, and transverse tube is then connected with vertical tube, uses
Air pump fans the air to transverse tube one end gas, air from the transverse tube other end out, due on transverse tube in vacuum tank
Air rapid flow cause pressure to increase, owing to vacuum tank external and internal pressure is poor, in case air pass through " T "
Type hollow circular-tube flows out, until being evacuated.
