Abstract
The utility model relates to a protection cover for a pumping plug of a heat insulation air bottle. The protection cover comprises a protective cap and a base which is welded on a heat insulation air bottle seal; the side wall of the protective cap is provided with a safety relief hole; the lower side of the base is a slope; and the protective cap and the base are fixedly connected. Due to the arrangement of the protective cap, injury of staff caused by the flying of the pumping plug the protective cap is avoided, and solid impurities following with gas emission is prevented when gas blows out; manual dismounting is judged by observing a plastic pin; when the bottle needs secondary vacuum pumping, the purpose can be achieved by just cutting the pin off and taking the protective cap down, and the operation is convenient and fast.
Description
Technical field
The utility model relates to a kind of protection structure of low-temperature pressure container, especially relates to the protective cover that a kind of insulated gas cylinder vacuumizes plug.
Background technique
Along with applying of economic development and modern technologies, as class gas usage such as rock gas, helium, oxygen, sharply strengthen, and low-temperature pressure container is by low-temperature storage liquid gas, the storage volume of comparing compression is larger, safer again, the automobile-used LNG(liquefied natural gas LNG Liquefied natural gas of special picture) gas cylinder, use amount rises year by year.Owing to carrying out storing liquefied gas by low temperature; therefore it is particularly important that thermal insulation property just seems; again owing to all adopting the structure of inside and outside two courages; by interlayer vacuum-pumping being reduced to heat transmission; reach insulation effect; thereby layer vacuum plays vital effect to gas cylinder performance, therefore also just particularly important to the protection of finding time to chew.
In existing industry, for the protective measure of finding time to chew, generally adopt serum cap, vinyl cover, and this just there is material aging, easily come off, easily by defects such as artificial damages.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of difficult drop-off and is easy to determine whether that the insulated gas cylinder of artificial damage vacuumizes the protective cover of plug.
The technical scheme in the invention for solving the technical problem is: a kind of insulated gas cylinder vacuumizes the protective cover of plug; described protective cover comprises safety cover and is welded on the base on insulated gas cylinder end socket; described safety cover sidewall is provided with safety relief hole; described base downside is inclined-plane, and safety cover is fixedly connected with base.
Further concrete, described base and safety cover are provided with corresponding pin-and-hole, are provided with plastic pin in pin-and-hole.
Further concrete, described safety relief hole is 8 and is uniformly distributed.
Further concrete, described safety cover downside is inclined-plane, at safety cover downside, is provided with semicircle welding hole.
Further concrete, described semicircle welding hole is 4 and is uniformly distributed.
The beneficial effects of the utility model are as follows: 1. when bottle interlayer occurs to leak, cause interlayer pressure to rise rapidly, finding time to chew plug will be flown out by top, due to speed, easily causes the accident, and had safety cover, can effectively prevent the injury that it flies out personnel etc. are caused; 2. when occurring to leak, bottle interlayer cause interlayer pressure to rise rapidly, find time to chew plug be ejected after, a large amount of gas is externally discharge directly, as being mixed with solid impurity in gas, be prone to accidents, and had safety cover, and because escape orifice is in side, the solid impurity that during gas ejection, safety cover is taken out of when just effectively barrier gas is discharged; 3. safety cover adopts plastic pin to be connected with base, in the time will taking off cover, must first plastic pin be destroyed, and can be so to have to have artificial dismounting by observing plastic pin judgement; 4. when bottle needs secondary vacuum pumping, only pin need be prescinded, take off guard shield, convenient and swift.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model safety cover;
Fig. 3 is the structural representation of the utility model base.
In figure: 1, safety cover; 2, safety relief hole; 3, plastic pin; 4, base; 5, semicircle welding hole; 6, pin-and-hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail.
A kind of insulated gas cylinder vacuumizes the protective cover of plug as shown in Figure 1, described protective cover comprises safety cover 1 and is welded on the base 4 on insulated gas cylinder end socket, described safety cover 1 sidewall is provided with safety relief hole 2, described base 4 downsides are inclined-plane (as shown in Figure 3), and safety cover 1 is fixedly connected with base 4; Described base 4 and safety cover 1 are provided with corresponding pin-and-hole 6, are provided with plastic pin 3 in pin-and-hole 6.
Safety relief hole on safety cover 12 is 8 and is uniformly distributed as shown in Figure 2; Safety cover 1 downside is inclined-plane, at safety cover 1 downside, is provided with semicircle welding hole 5; Described semicircle welding hole 5 is 4 and is uniformly distributed.
When installing; first; the base 4 that the safety cover 1 that aluminium is made and stainless steel material are made links together by plastic pin 3; safety cover 1 is covered on and finds time to chew; mode by welding is interior spot-welded together by base 4 and end socket at semicircle welding hole 5; due to interlayer internal pressure, cross senior general and find time to chew the accident that plug top flies to hurt sb.'s feelings and greatly reduce occurring like this, guaranteed its Security.
It is emphasized that above is better implementation column of the present utility model, and any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
