Embodiment
This verifying attachment that is used for ship hull weld joint air-tight is made of filament plate 8 and pump gas silking rapid-acting coupling assembly, this pump gas silking rapid-acting coupling assembly comprises a two-way attaching nut 7, two rapid-acting coupling 6,6 ＇, is with manometric three-way pipe 5, through type stop valve 3 and tracheae connector 1; According to filament plate 8, two-way attaching nut 7, rapid-acting coupling 6, be with manometric three-way pipe 5, through type stop valve 3, rapid-acting coupling 6 ＇, tracheae connector 1 composition that is linked in sequence.
Described filament plate 8 ＇ are provided with the tensimeter of a band rapid-acting coupling.
This ship hull weld joint air-tight pump pressure verifying attachment that is used for, its using method is as follows:
A, at first require to mark the filament plate installation position according to weld seam watertightness on the body section drawing, after steel plate cutting, before the assembling, the section port that the steel plate member that watertightness requires is arranged made to recognize obvious sign, and the steel plate member section parts that has watertightness to require is carried out the laggard luggage of processing of rust removing join, carry out the cleaning of welded seam area before welding, must keep the airway unobstructed no-sundries, guaranteeing has the air flue gap in the weld seam.
B, the position section A, the A that demarcate by the segmentation drawing at the weld seam two ends
1 placeEach welds filament plate 8,8 ＇ that a block check is used, wherein filament plate 8 ＇ joint detection device C
1, whether unimpeded 8 of another piece filament plates connect measures welding line air pressure verifying attachment C; In the leak-stopping hole of respectively opening one 20mm * 20mm with weld seam two thread plate outside, and wrap weldering along the slit, the device assembles of finishing before the check is prepared.
C, pump gas joint is inserted rapid-acting coupling place of source of the gas end connect check and survey device, introduce detection place of exerting pressure of 0.02Mpa air pressure butt welded seam, be coated with suds outside whole section tested commissure, all gas leakage foamings place then are judged to be the gas leakage point, then discharge air pressure, leak source is carried out repair welding; So hunt leak piecemeal repeatedly, repair welding, up to the check of finishing whole weld seams, repair welding operation.
To carry out the preliminary work in early stage in the past according to following steps in concrete detection:
1, on the body section drawing, marks the requirement of corresponding tightness of welding lines.And mark the filament plate installation position.
2, after steel plate cutting, before the assembling.Section port to steel plate member that the watertight requirement is arranged is made sign
3, have the steel plate member section port position of watertight requirement to eliminate rust, the no-sundries that keeps clean assembles then.More than operation is convenient to weld back weld seam pressure air smoothness.
4, before welding, at first want the clean welds zone, guarantee the air flue no-sundries; The molten degree of depth of GPRS wlding during welding, guaranteeing has certain clearance in the weld seam.Welding current will be regulated suitably, not with air flue gap through welding, in order to avoid the molten dark obstructing airway of wlding.Be welded with the weld seam of watertight requirement, preferably operate by the special messenger.
5, filament plate should be 5 ° and tiltedly puts.That is: reserve the 2mm gap in commissure, filament plate base, to guarantee airway unobstructed.Periphery carries out the watertight welding.
6, respectively welding a filament plate (fixed) with weld seam two ends by the segmentation drawing.A filament plate air inlet is used; Another piece filament plate is installed is and measure the whether terminal pressure meter connector of unimpeded usefulness of welding line air pressure.
7, near the weldering of the leak-stopping hole of the same outside of weld seam two thread plates, respectively opening a 20mm * 20mm, and Yan Fengxibao.
8, steel plate member welding back (needing two-sided welding) can carry out the weld joint air-tight pump pressure check.The tightness of welding lines pneumatic test
L, pump gas joint insert origin or beginning rapid-acting coupling; Install the silking joint endways
One of mm0～0.16Mpa tensimeter.
2, connect " air-tight pump pressure joint " from compressed air distributor with the 15m sebific duct, introduce the 0.02Mpa air pressure, butt welded seam is exerted pressure.
3, may be coated with suds by air-leak section at weld seam, air-leak section may bubble.Irising out leak source with pen is sign.Discharge air pressure then, leak source is carried out repair welding.
4, after leak source has been caught, repeat above-mentioned 1,2,3, workflow again.Confirm no leak source, treat that the pump atmospheric pressure is stable after, can file an application to apply for checking and examination.
5, apply for checking and examination successfully, be considered as this work and finish.At last that filament plate mouth and the electricity consumption soldering of leak-stopping hole is flat.Vacuumize with vacuum (-tight) housing in repair welding place.Confirm to enter next procedure behind the no leak source.
