Design of the present utility model is to meet under the technical requirement of such weld seam leak test detection and the prerequisite of safety in production, design a kind of novel, simple and easy, circular vacuum tank of on-the-spot leak test efficiently, can meet preferably the requirement of this type of project progress, quality and cost aspect.
Summary of the invention
The purpose of this utility model is, provides a kind of tank back welding seam leak test circular vacuum tank, to realize the base plate weld seam of quick, accurate, economic vertical cylindrical steel welding oil tank, carries out leak test detection.
The purpose of this utility model and solve its technical matters and realize by the following technical solutions.According to the circular vacuum tank of tank back welding seam leak test the utility model proposes, it comprises scum rubber cylindrical shell, poly (methyl methacrylate) plate, vacuum meter, find time mouth and drain, wherein this poly (methyl methacrylate) plate is closely connected with one end of this scum rubber cylindrical shell, and this vacuum meter, this is found time mouthful and this drain is arranged on this poly (methyl methacrylate) plate.
The purpose of this utility model and solve its technical matters and also can be applied to the following technical measures to achieve further.
The circular vacuum tank of aforesaid tank back welding seam leak test, wherein this poly (methyl methacrylate) plate is circular, and its diameter is identical with the external diameter of this scum rubber cylindrical shell one end.
In other words, for completing the purpose of this utility model, adopt following technical scheme:
1. vacuum box structure: tank back welding seam leak test of the present utility model is columnar structured with the whole employing of circular vacuum tank, take scum rubber as cylindrical shell, and top seals with poly (methyl methacrylate) plate;
2. hermetically-sealed construction: this vacuum tank adopts scum rubber as cylindrical shell, the encapsulant while also contact with tank bottom as vacuum tank, easily purchases, easily processes simultaneously, and can Reusability;
3. operating structure: this vacuum tank is established 3 perforates on the poly (methyl methacrylate) plate of top, respectively as pressure observe, find time, emptying used, easy to operate, quick.
By technique scheme, the utility model at least has following advantages and beneficial effect: tank back welding that the utility model provides seam leak test is simple with circular vacuum box structure, easily manufacture, lightweight, easily move, easy to operate, it is clear to observe, meet preferably the needs that such weldquality checks, there is good economic benefit.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of instructions, and for above and other object of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is the structural representation of circular vacuum tank for tank back welding seam leak test of the present utility model.
Embodiment
For further setting forth the utility model, be to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, tank back welding according to the utility model proposes is stitched to its embodiment of circular vacuum tank, structure, feature and effect thereof for leak test, be described in detail as follows.
As shown in Figure 1, tank back welding seam of the present utility model circular vacuum tank 10 for leak test, comprise scum rubber cylindrical shell 1, poly (methyl methacrylate) plate 2, vacuum meter 3, find time mouthfuls 4 and drain 5, wherein this poly (methyl methacrylate) plate 2 is closely connected with one end of this scum rubber cylindrical shell 1, this vacuum meter 3, this find time mouthfuls 4 and this drain 5 be arranged on this poly (methyl methacrylate) plate.
In one embodiment, this tank back welding seam leak test is as follows by the method for making of circular vacuum tank 10: with the thick foam rubber sheet of 40mm, make the cylindrical body that external diameter is 50cm, be highly controlled at 120mm left and right.Preparing a diameter is 50cm, the poly (methyl methacrylate) plate that thickness is 6mm, and top drills through 3 openings, with multi-purpose adhesive, is bonded in closely scum rubber cylindrical shell one end.At 3 tappings of poly (methyl methacrylate) plate, a vacuum meter is installed respectively, one find time mouthful (during leak test, connecting vacuum pump uses), a drain, and mounted valve is controlled respectively.Certainly, tank back welding seam leak test of the present utility model is not limited with this embodiment by the size of circular vacuum tank, and those skilled in the art can adjust flexibly according to the utility model; In addition, the shape of this poly (methyl methacrylate) plate and size also can be for sealing up arbitrarily the pattern of this scum rubber cylindrical shell one end, from saving material and realizing vertical cylindrical steel and weld the angle consideration that the base plate weld seam of oil tank can carry out complete detection, preferably this poly (methyl methacrylate) plate is circular, and its diameter is identical with the external diameter of this scum rubber cylindrical shell one end.
At application tank back welding seam of the present utility model leak test, with circular vacuum tank, carry out before leak test detection, need carry out following preliminary work: will in tank body to be detected, clean out, particularly the coating complete liquidation of weld seam to be detected is clean, can carry out vacuum leakage test detection.Meanwhile, be ready to the aids such as vacuum pump, vacuum meter, brush, liquid soap.
Concrete testing process is as follows: before leak test, first at tank back welding, sew on spraying liquid soap, then vacuum tank is placed on to weld seam top, guarantee that weld seam is in the middle of vacuum tank, conveniently by the poly (methyl methacrylate) plate at top, observe, and guarantee bottom and tank body good seal.Open vacuum meter operation valve, open mouthful operation valve of finding time, close atmospheric valve, with vacuum pump, will in casing, vacuumize, observe vacuum meter and determine be low to moderate-53kPa of pressure.Now, by the poly (methyl methacrylate) plate of vacuum tank bottom, observe weld seam to be checked.If weld seam has leakage, will produce bubble at leak source; If no abnormality seen situation, illustrates that tank bottom weldquality is good.Close vacuum pump operation valve, open atmospheric valve, move chest to next commissure to be checked, repeat according to this, until weld seam has all detected.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
