Abstract
Provided is a storage tank base plate vacuum test box, characterized in that an organic glass plate is provided with two equal-sized holes, with one hole being connected with a gas source pipe of a vacuum pump while the other hole being provided with a negative pressure gauge; the center of a resin cystose is cut into an opening frame; and the organic glass plate and the resin cystose are bound together for sealing the opening frame. With a storage tank base plate vacuum test box of the utility model, the welding line detecting speed via vacuum test is substantially raised during the storage tank construction process. The storage tank base plate vacuum test box of the utility model allows one person to complete the operation of the whole vacuum test, thereby substantially raising the working efficiency. The whole height of the vacuum test box is no greater than 100 mm, that is to say, the distance between the organic glass plate and the welding line is just like the height of the a piece of resin cystose while the user carries out vacuum operation, thereby allowing users to clearly and accurately watch the welding line and accordingly find out whether there exist pores or not.
Description
Technical field
The utility model relates to a kind of large-scale storage tank base plate vacuum test instrument.
Background technology
After storage tank bottom plate construction welding is in the past finished, the old-fashioned vacuum tank of general employing, namely adopt the vacuum tank of iron plate welding fabrication, use very clumsy, contact imprecision with base plate, the most old-fashioned vacuum tank still uses powder of lacquer putty for use on as encapsulant, and spray after the suds on the limit in welded joints, can't clearly see whether the weld seam top exists pore under the irradiation of sunlight and when forming easily water vapour and causing vacuumizing, and can not clearly see the base plate weld seam.In addition in vacuum, this type of vacuum tank can not allow unlimited the vacuumizing of vacuum pump.Because the intensity that the sealing that powder of lacquer putty for use on is done can bear is limited, a some gas leakage is sometimes arranged at once just with in the putty suction vacuum tank that seals.The operator also needs again to clear up vacuum tank, and then re-starts and vacuumize test, has both wasted the time like this, has also wasted the material of operation.
The utility model content
The purpose of this utility model provide a kind of light, contact tightly with base plate, vacuum test case that can clear observation weld seam, overcome all unfavorable factors that traditional concept is brought.
For achieving the above object, the utility model provides a kind of storage tank bottom plate vacuum test case, it is characterized in that: poly (methyl methacrylate) plate is provided with the identical hole of size, two places, a hole connects the gas source pipe of vacuum pump, the negative pressure tensimeter is installed in a hole, the heartcut of resin foamed plate becomes an openning frame, and poly (methyl methacrylate) plate and resin foamed plate are bonding, is used for sealing openning frame.
By using vacuum tank of the present utility model, in the Storage Tank Construction process, increased substantially the speed of vacuum test detection weld seam, because new-type vacuum tank has just reduced 15Kg than old-fashioned vacuum tank on weight, old-fashioned vacuum tank a people can't operate at all, and the shortage in weight 5Kg of vacuum tank of the present utility model, a people just can carry out the operation of whole vacuum test.Ten ten thousand stere Tank base plates need to vacuumize weld seam and be about 2100 meters, adopt old-fashioned vacuum tank to operate, every day, every vacuum tank needed to dispose 2 pincers worker at least, at utmost can finish about about 100 meters of vacuum weld seam every day, be exactly 2 pincers worker, worked about 11 days; And adopt after the vacuum tank of new utility model, be equipped with a pincers worker just can operate, can finish at least for each person every day 200 meters with the upper plate weld inspection, as long as 1 pincers worker just can be finished the work in 5 days.On personnel amount and work efficiency, all occupy absolute advantage.New-type vacuum tank obviously is fit to on-the-spot use than old-fashioned vacuum tank more on result of use: the whole height of new-type vacuum tank is no more than 100mm, equaling our poly (methyl methacrylate) plate when carrying out vacuum operation only has the height of a resin foam apart from weld seam, whether energy is clear and see accurately weld seam clearly, have pore to exist thereby reach clear seeing.And old-fashioned vacuum tank adopts black iron plate and angle steel, has sheltered from the light irradiation, does not see the base plate weld seam.
Use the material aspect, the vacuum tank of new utility model has saved the employed iron plate of old-fashioned vacuum tank and angle steel, only just can produce vacuum tank with lightweight organic glass and resin foam, also satisfies than being easier in material purchases.
Through practice, the poly (methyl methacrylate) plate that 20mm is thick can satisfy-the negative pressure test of 70KPa, and the storage tank bottom plate vacuum test as long as satisfy-35KPa just can, can poly (methyl methacrylate) plate not caused damage, can satisfy the needs of constructing fully.
Description of drawings
Fig. 1 is poly (methyl methacrylate) plate and resin foamed plate bonded structure graph of a relation;
Fig. 2 is side view of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, poly (methyl methacrylate) plate 2 is provided with the identical hole 3,4 of size, two places, and hole 3 connects the gas source pipe of vacuum pump, the negative pressure tensimeter is installed in hole 4, the heartcut of resin foamed plate 1 becomes an openning frame, and poly (methyl methacrylate) plate and resin foamed plate are bonding, is used for sealing openning frame.
During use, fastening bolt 5,7th, vacuum pump interface are installed by sealing gasket 8 by 3 places in the hole.
