Abstract

The utility model relates to a leakage stopping device for a tank body of a liquefied gas spherical tank, which is a hand-operated tool special for leakage stopping of liquefied gas. The technical scheme is that a compaction hand wheel (2), a leakage stopping shade (3) and a pair of split reversed suspension cross rods are sequentially equipped on a leakage stopping retention bolt rod (1); a drainage tube (6) is arranged on the side surface of the leakage stopping shade; a drainage switch (5) is mounted on the drainage tube (6). The leakage stopping device is used for the leakage stopping of the tank body of the liquefied gas spherical tank, can stop up a leakage mouth more quickly, and prevents the liquefied gas from being further leaked; the operation of leakage stopping is performed on the spherical tank body so as to improve rescue efficiency.

Description

Liquifier spherical tank tank body leak stoppage device

Technical field

The utility model provides a kind of tank body leak stoppage device, specifically a kind of liquifier spherical tank tank body leak stoppage device.

Background technique

Burning or the blast of liquid gas, in the situation that shock and the leakage accident that causes that scratches happen occasionally, very easily occur in lpg spherical tank.In the emergency management and rescue that lpg spherical tank leaks were disposed, leakage stopping technology was very crucial Disposal Measures.Due to the effect of clashing into and scratching, the leakage hole surface configuration on spherical tank surface generally is irregular and out-of-flatness, brings difficulty for the stand-by service of leak stopping, so research is efficient, leak stoppage tool, dispose particularly important for the lpg spherical tank leakage accident easily.

At present, common rescue technology has: the one, and gas-filled type rubber leak stoppage instrument, as gas-filled type rubber tape external sealing type leak stoppage device, be banded in rubber tape on the tank body tank skin, and then pressurization inflation, utilize the expansion of inflating rubber band to block leakage hole; Gas-filled type rubber body internal sealing type leak stoppage device, at leakage hole, then pressurization inflation, utilize the inflating rubber body to expand and carry out leak stopping at the leakage hole place by inflating rubber body plug; Gas-filled type rubber Small-pore Leak Stoppage Rifle, the leakage mouth for little, advance aperture by the charge gun screw plug, and then pressurization inflation, utilize the expansion of rifle head, at the leakage hole place, implements leak stopping.Above inflating rubber leak stoppage utensil, only applicable surfacing, the leakage hole of rule, but in actual leakage accident, the tank skin at leakage hole place is often that tank body turns up, shape distortion, and above three kinds of leak stoppage tools and mode are difficult to prove effective.The 2nd, magnetic pressure type leak-stopping tool, be only applicable to tank surface smooth, the leakage hole of rule, and applicable object is single.In recent years, the magnetically pressing leakage blockage of tank body leakage has appearred disposing, but its complex structure, comparatively loaded down with trivial details during dismounting, manufacture cost is higher.The 3rd, the injection rubber type leak stoppage tool, this instrument needs and " fixture " supports the use, and normally for flange leakage, implements plugging operations, can't implement leak stopping to tank body.And this Plugging device complex structure, price is higher.

For this reason, create convenient and practically, the special type leak stoppage device is necessary very much targetedly.

Summary of the invention

Goal of the invention of the present utility model just is to provide a kind of portably using conveniently, and is safe and reliable, effectively the special manual liquifier spherical tank tank body leak stoppage device of leak stopping.

Realize that the technical solution of the utility model is such: liquifier spherical tank tank body leak stoppage device, comprise leak stopping maintenance screw rod, pressing handwheel, the drainage switch, the members such as drainage tube, on leak stopping maintenance screw rod (1) successively supporting be equiped with pressing handwheel (2), leak stopping cover (3) but and folding reversal of the natural order of things cross bar (4) in pairs, in the side of leak stopping cover (3), be provided with drainage tube (6), drainage switch (5) is housed on drainage tube (6).

The beneficial effects of the utility model are: in the breakage of lpg spherical tank tank body, in the accident rescue of gas leak, use this instrument, can faster leakage hole be blocked, stop the further leakage of liquid gas, save personnel's life, reduce property loss.Use this equipment to implement the spherical tank leak stopping, can improve greatly rescue efficiency, have adaptability, safety and stability preferably.The manufacture of this equipment and maintenance cost are cheap, science simple in structure, and handling safety is convenient, is convenient to popularize.Especially during icing after the leakage hole place is due to gas leak, because the protuberance space of leak stopping cover inside is larger, do not need deicing can implement leak stopping, prevented personnel's frostbite danger yet.

The accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present utility model.

In figure, the 1st, leak stopping maintenance screw rod, the 2nd, pressing handwheel, the 3rd, the leak stopping cover, the 4th, but folding reversal of the natural order of things cross bar, the 5th, drainage switch, the 6th, drainage tube.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described as follows:

Embodiment: liquifier spherical tank tank body leak stoppage device

But concrete structure be on leak stopping maintenance screw rod 1 supporting have pressing handwheel 2, and cover leak stopping cover 3 is arranged, is equiped with folding reversal of the natural order of things cross bar 4 in pairs under it, in the side of leak stopping cover 3, be provided with drainage tube 6, drainage switch 5 be housed on it.

Leak stopping cover 3 is circular indent design, and edge arranges Stamping Steel Ribbon, when compressing, can play good seal action.Can do according to different sizes at ordinary times severally, scene can choice for use more.Drainage switch 5 on the leak stopping cover and drainage tube 6 are convenient to the defeated tank switching that turns of the liquid gas after leak stopping, and can metal interface be set at the end of drainage tube, so that the enforcement of igniting emptying rescue means.

But the paired folding reversal of the natural order of things cross bar 4 of the lower end of leak stopping maintenance screw rod 1 installing, collapsiblely when inserting leak be integrated with bar, after entering, can automatically spring open, and forms and hang upside down, and plays positioning action.Cross bar can be arranged to two, three or four.

During use, leak stopping maintenance screw rod 1 is aimed to leak and insert, with cover cap, live leak, then reverse pressing handwheel 2 the leak stopping cover is compressed and can realize leak stopping.

Claims

1. liquifier spherical tank tank body leak stoppage device, comprise leak stopping maintenance screw rod, pressing handwheel, drainage switch and drainage tube, it is characterized in that: on leak stopping maintenance screw rod (1) successively supporting be equiped with pressing handwheel (2), leak stopping cover (3) but and folding reversal of the natural order of things cross bar (4) in pairs, in the side of leak stopping cover (3), be provided with drainage tube (6), drainage switch (5) is housed on drainage tube (6).

2. liquifier spherical tank tank body leak stoppage device according to claim 1 is characterized in that: leak stopping cover (3) is circular indent design, and edge arranges Stamping Steel Ribbon.
