Abstract
The utility model discloses a vacuum chamber that is used for basin welding seam gas tightness to detect, box including semi -closed form, the box adopts the band steel to make, the top of box is sealed through transparent organic glass, and the bottom of box is opening status, and the bottom of box is equipped with the rubber sponge board that the round is used for sealed welding seam, one side of box is passed through the gas outlet and is connected the vacuum pump, the absorption of rubber sponge board is sealed around the basin welding seam, and suds are evenly paintd on the surface to the welding seam, the utility model discloses simple structure, convenient to use is applicable to the job site and does existing usefulness at present, has practiced thrift the cost, has guaranteed welding quality moreover.
Description
Technical field
The utility model is related to a kind of air leakage detection tool, more particularly to a kind of for the true of basin weld joint air-tight detection
Empty van.
Background technology
In the basin job site of petroleum chemical industry, generally it is required for being subjected to.Then sometimes because behaviour
Make carelessness or other extraneous factors of personnel, the situation for causing the weld seam for welding to have gas leakage is produced, if do not carried out to weld seam
Detection, the imprecision of weld seam easily causes the quality problems of whole basin.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of vacuum tank for the detection of basin weld joint air-tight,
The vacuum box structure is simple, easy to operate, it is adaptable to which that job site is now done and first used, and has saved cost, it is ensured that welding quality.
To achieve the above object, the utility model provides following technical scheme：It is a kind of to be examined for basin weld joint air-tight
The vacuum tank of survey, including semiclosed shape casing, the casing is made of band steel, and the top of the casing is by transparent organic
Glass capsulation, the bottom of casing is open state, and the bottom of the casing is provided with a circle for the rubber sea of seal-weld
Continuous plate, the side of the casing connects vavuum pump by gas outlet, and the cellular rubber plate absorption is sealed in the week of basin weld seam
Enclose, and uniform application suds on the face of weld.
Preferably, the side of casing is also equipped with vacuum table, and pressure-reducing valve is installed on the another side of casing.
Preferably, the two ends end of casing is provided with angle steel.
Using above-mentioned technical proposal, when the air-tightness of weld seam is detected, cellular rubber plate is attached to around basin weld seam,
Then air is extracted by vavuum pump, makes to produce negative pressure in vacuum tank, cellular rubber plate is pressed downward in the presence of negative pressure, so that
Seal up weld seam.And if now weld seam contains stomata, then in the presence of vavuum pump, the stomata of weld seam can then ventilate, from
And the suds for being coated in face of weld is produced bubble, and operating personnel then can observe weld seam table by transparent organic glass
The situation in face.The utility model simple structure, it is easy to use, it is adaptable to which that existing use is now done in job site, save cost, Er Qiebao
Welding quality is demonstrate,proved.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the A-A sectional views of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings, by the description to embodiment, the utility model is described further：
As shown in Figure 1, 2, a kind of vacuum tank for the detection of basin weld joint air-tight of the utility model, including semiclosed shape
Casing 1, the casing 1 is made of band steel, and the two ends end of casing 1 is provided with angle steel 7, and such casing 1 can increase
Weight, in order to have more sealing in seal-weld.The top of casing 1 is sealed by transparent organic glass 2, casing 1
Bottom is open state, and the bottom of the casing 1 is provided with a circle for the cellular rubber plate 3 of seal-weld, the casing 1
Side by gas outlet connect vavuum pump 4, the side of casing 1 is also equipped with vacuum table 5, for observing the negative pressure in casing 1
Situation, installs pressure-reducing valve 6 on the another side of casing 1, for protecting casing 1, the absorption of cellular rubber plate 3 is sealed in basin
Around weld seam, and uniform application suds on the face of weld.
The utility model is dry by polishing is cleared up in the range of weld seam and weld seam both sides 50mm before the air-tightness of detection weld seam
Only, cellular rubber plate 3 is attached to around basin weld seam again then, air is extracted by vavuum pump 4, made to be produced in vacuum tank and bear
Pressure, cellular rubber plate 3 is pressed downward in the presence of negative pressure, so as to seal up weld seam.And if now weld seam contains stomata, then
In the presence of vavuum pump 4, the stomata of weld seam can then ventilate, so that the suds for being coated in face of weld produce bubble.Operation
Personnel can then observe the situation of face of weld by transparent organic glass 2, so as to detect the airtight sex chromosome mosaicism of weld seam, such as
Fruit detects qualified, then vacuum tank can be forward elapsed, until all weld seam detections are finished.
The utility model simple structure, it is easy to use, it is adaptable to which that existing use is now done in job site, save cost, Er Qiebao
Welding quality is demonstrate,proved.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.
