Description
Technical field
The invention belongs to petrochemical unit and build installing area, be mainly concerned with in petrochemical unit vertical and cylindrical welding storage tank site operation process the simple machine that at the bottom of tank, weldquality leak test detects.
Background technology
In petrochemical unit installation process, the base plate weld seam of vertical cylinder steel welding oil tank is the Focal point and difficult point of Engineering Quality Control.How quick, accurate, economical this type of weld seam is carried out to leak test detection, be the important process content in oil tank installation process always.
Design of the present invention 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 object of the invention is to, provide a kind of tank back welding seam leak test circular vacuum tank, carry out leak test detection with the base plate weld seam of realizing quick, accurate, economic vertical cylindrical steel welding oil tank.
The object of the invention to solve the technical problems realizes by the following technical solutions.The circular vacuum tank of tank back welding seam leak test proposing according to the present invention, 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 object of the invention to solve the technical problems 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, adopt following technical scheme for completing object of the present invention:
1. vacuum box structure: tank back welding seam leak test of the present invention adopts columnar structured by circular vacuum tank entirety, taking scum rubber as cylindrical shell, top seals with poly (methyl methacrylate) plate;
2. hermetically-sealed construction: this vacuum tank adopts scum rubber as cylindrical shell, the encapsulant while simultaneously also contact with tank bottom as vacuum tank, easily purchases, easily processes, 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 uses, easy to operate, quick.
By technique scheme, the present invention at least has following advantages and beneficial effect: tank back welding provided by the invention 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 solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Brief description of the drawings
Fig. 1 is the structural representation of the circular vacuum tank of tank back welding seam leak test of the present invention.
Embodiment
Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, the tank back welding proposing according to the present invention 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 invention 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: make with the thick foam rubber sheet of 40mm 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, is bonded in closely scum rubber cylindrical shell one end with multi-purpose adhesive.At 3 tappings of poly (methyl methacrylate) plate, a vacuum meter is installed respectively, one find time mouthful (when leak test, connecting vacuum pump uses), a drain, and mounted valve is controlled respectively.Certainly, tank back welding seam leak test of the present invention 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 present invention; 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, can carry out the angle of complete detection considers from the base plate weld seam of saving material and realizing vertical cylindrical steel welding oil tank, 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.
Carry out before leak test detection with circular vacuum tank at application tank back welding seam of the present invention leak test, 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 sews on spraying liquid soap at tank back welding, then vacuum tank is placed on to weld seam top, guarantee that weld seam is in the middle of vacuum tank, and the convenient observation of the poly (methyl methacrylate) plate by top, and guarantee bottom and tank body good seal.Open vacuum meter operation valve, open mouthful operation valve of finding time, close atmospheric valve, will in casing, vacuumize with vacuum pump, observe vacuum meter and determine be low to moderate-53kPa of pressure.Now, observe weld seam to be checked by the poly (methyl methacrylate) plate of vacuum tank bottom.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 invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, 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 solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
