Description
Technical field
Lpg filling technical field is the utility model is related to, particularly relates to a kind of tamper of cylinder for liquefied gas
Anti-down device of air.
Background technology
In recent years, liquefied gas has quickly entered huge numbers of families as a kind of New-type fuel, but due to filling liquefied gas
Cylinder for liquefied gas security risk that may be present, the person of entail dangers to user and the safety of property.
At present, in lpg filling industry, have it is many it is non-normal fill business, these, which are filled, does not fill money a little
Matter, filling equipment and fills the requirement that technology does not reach national regulation, and when being inflated to cylinder for liquefied gas, there are larger safety
Hidden danger.
To ensure user's security of the lives and property, the liquefied gas cylinder valve used at present has the function of that fixed point fills, and then
So that cylinder for liquefied gas fills mode using fixed point, can be the management archives of cylinder for liquefied gas Erecting and improving.But above-mentioned valve
Door is actual in use, violation operation or malicious sabotage（Such as valve can be opened using strong magnetic or when steel cylinder is deflated）,
Cylinder for liquefied gas limit is caused to fill failure, causing the use of cylinder for liquefied gas, there are larger security risk, serious threat user
The security of the lives and property.
Bigger steel cylinder liquefied gas is inverted by illegal fill, and is connected, made by tracheae with small steel cylinder liquefied gas
Big steel cylinder liquefied gas leads small steel cylinder, so operates abnormally dangerous, is easily fallen first, big steel cylinder is inverted, second, two kinds of mixing not
It is that a liquefied gas quality stood is bad.
Utility model content
For deficiency of the prior art, the technical problems to be solved in the utility model is the provision of a kind of liquefied gas steel
The anti-down device of air of tamper of bottle.
In order to solve the above technical problems, the utility model is realized by following scheme：A kind of cylinder for liquefied gas is prevented
Tear anti-down device of air open, the anti-down device of air of the tamper is arranged in the cavity of valve body lower end, valve body lower end cavity to spool it
Between feeder connection at be provided with taper surface, anti-down balloon pearl, the anti-down gas are provided with the cavity near the taper surface
The diameter of ball is greater than the through-hole diameter of taper surface bottom；
Antiwithdrawal device is provided with the cavity inner wall of valve body lower end, which includes cylinder bar, easily spring, fusion
Golden part, through hole is provided at both ends with the cavity inner wall diameter of the valve body lower end, and the fusible alloy part is the circle of one end open
Column box body, the cylinder box body edge of opening turn up, and spring sleeve column and flange collar have been cut in the cylinder bar front end, and the cylinder bar is from valve
The inside cavity of body lower end passes outwards through one through hole of inner wall, and the fusible alloy part is from the inside cavity of valve body lower end to overcoat
On inner wall another through hole, the spring one end is sleeved on spring sleeve column, and the other end is withstood in the inner groovy of fusible alloy part；
The anti-down balloon integument antiwithdrawal device blocks.
Further, the anti-down balloon pearl includes one in metal ball body, plastic sphere, rubber ball body, glass spheres
Kind.
Relative to the prior art, the beneficial effects of the utility model are：The tamper of the utility model cylinder for liquefied gas is prevented
Device of air prevent it is non-fill inflation, after big steel cylinder is inverted by it, the anti-down balloon pearl in valve body can block venthole,
Liquefaction conductance is set not go out.Steel cylinder oral area is provided with bayonet, antiwithdrawal device can be installed at bayonet, prevent informal fill a little
Remove valve body.
Brief description of the drawings
Fig. 1 anti-down balloon pearl opening channel design schematic diagrames when being the valve that the utility model is just being put；
Fig. 2 for the utility model inverted valve when anti-down balloon pearl block channel design schematic diagram.
Embodiment
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make the scope of protection of the utility model apparent clear and definite
Define.
Attached drawing 1-2, a kind of anti-down device of air of the tamper of cylinder for liquefied gas are refer to, the anti-down device of air of the tamper is arranged at
In the cavity of 1 lower end of valve body, taper surface is provided with cavity to the feeder connection between spool 2 of 1 lower end of valve body, in the cone
Anti-down balloon pearl 3 is provided with cavity near shape face, the diameter of the anti-down balloon pearl 3 is greater than the through hole of taper surface bottom
Diameter；
Be provided with antiwithdrawal device at the cavity inner wall of 1 lower end of valve body, the antiwithdrawal device include cylinder bar 5, spring 4, easily
Alloy components 6 are melted, are provided at both ends with through hole at the cavity inner wall diameter of 1 lower end of valve body, the fusible alloy part 6 is opened for one end
The cylinder box body of mouth, the cylinder box body edge of opening turn up, and spring sleeve column and flange collar, the column have been cut in 5 front end of cylinder bar
The inside cavity of body rod 5 from 1 lower end of valve body passes outwards through one through hole of inner wall, chamber of the fusible alloy part 6 from 1 lower end of valve body
Internal portion is outwards sleeved on inner wall another through hole, and described 4 one end of spring is sleeved on spring sleeve column, and the other end withstands on fusible alloy
