Abstract
The present invention relates to the protective cover that a kind of insulated gas cylinder vacuumizes 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, and described Its lower side is inclined-plane, and safety cover is fixedly connected with base.There is safety cover, then can effectively prevent from finding time to chew filling in the injury caused personnel etc. that flies out; Had safety cover, because escape orifice is in side, during gas ejection, safety cover just can solid impurity that take out of when effectively barrier gas is discharged; Judge it is have to there is artificial dismounting by observing plastic pin; When bottle needs secondary vacuum pumping, only pin need be prescinded, take off guard shield, convenient and swift.
Description
Technical field
The present invention relates to a kind of operator guards of low-temperature pressure container, especially relate to the protective cover that a kind of insulated gas cylinder vacuumizes plug.
Background technique
Along with applying of economic development and modern technologies, sharply strengthen as class gas usage such as rock gas, helium, oxygen, and low-temperature pressure container is by low-temperature storage liquid gas, the storage volume comparing compression is larger, safer again, special in automobile-used LNG(liquefiednaturalgas LNG Liquefied natural gas) gas cylinder, use amount rises year by year.Owing to carrying out storing liquefied gas by low temperature; therefore thermal insulation property just seems particularly important; again owing to all adopting the structure of inside and outside two courages; by reducing heat trnasfer to interlayer vacuum-pumping; reach insulation effect; thus layer vacuum plays vital effect to gas cylinder performance, therefore the protection of chewing finding time is also just particularly important.
In existing industry, the protective measure of chewing for finding time generally adopts serum cap, vinyl cover, and this just exists material aging, easily comes off, easily by defects such as artificial damages.
Summary of the invention
Technical problem to be solved by this invention 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 present invention solves the technological scheme that its technical problem takes: 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 Its lower side is inclined-plane, and safety cover is fixedly connected with base.
Concrete further, described base and safety cover are provided with corresponding pin-and-hole, are provided with plastic pin in pin-and-hole.
Concrete further, described safety relief hole is 8 and is uniformly distributed.
Concrete further, be inclined-plane on the downside of described safety cover, side is provided with semicircle welding hole under its protective cover.
Concrete further, described semicircle welding hole is 4 and is uniformly distributed.
Beneficial effect of the present invention is as follows: 1. when bottle interlayer generation leakage causes interlayer pressure to rise rapidly, find time to chew plug to be flown out by top, due to speed, easily cause the accident, and had safety cover, then effectively can prevent its injury that personnel etc. are caused that flies out; 2. when bottle interlayer generation leakage causes interlayer pressure to rise rapidly, find time to chew after plug is ejected, a large amount of gas directly externally discharges, as being mixed with solid impurity in gas, then be prone to accidents, and had safety cover, because escape orifice is in side, during gas ejection, safety cover just can solid impurity that take out of when effectively barrier gas is discharged; 3. safety cover and base adopt plastic pin to be connected, and when taking off cover, must first plastic pin be destroyed, and so judge it is have to there is artificial dismounting by observing plastic pin; 4., when bottle needs secondary vacuum pumping, only pin need be prescinded, take off guard shield, convenient and swift.

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 present invention 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, be inclined-plane (as shown in Figure 3) on the downside of described base 4, 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 2 as shown in Figure 2 on safety cover 1 is 8 and is uniformly distributed; Be inclined-plane on the downside of safety cover 1, on the downside of safety cover 1, be 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 make aluminium and stainless steel material make is linked together by plastic pin 3; safety cover 1 is covered on and finds time to chew; by the mode of welding semicircle welding hole 5 in by base 4 and end socket spot-welded together; find time to chew plug and push up the accident flying to hurt sb.'s feelings and greatly reduce occurring to cross senior general due to interlayer internal pressure like this, ensure that its Security.
It is emphasized that above is better implementation column of the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
