Abstract
The utility model discloses a kind of globular pressure-container and deflation structure thereof.Deflation structure includes that air relief cock is provided with the weak structure opening gas vent when being impacted or impact for breaking for blocking the air relief cock being arranged on the gas vent of vessel.In the utility model, air relief cock plays the effect of the gas vent of blocking container body, and when vessel is exitted by needs, after only the weak structure on air relief cock need to being broken, air relief cock is opened from gas vent, gas in vessel can be released, so in stored condition formula, air relief cock ensures that the gas vent of vessel is in integrated sealing state, only in the case that damage type is opened, just can open the gas vent of vessel, therefore this deflation structure solves valve in prior art and descends the problem that gases at high pressure still can slowly be revealed in off position, whole globular pressure-container is made to have the advantage that long-term storage is difficult to reveal.
Description
Technical field
The utility model relates to a kind of globular pressure-container and deflation structure thereof.
Background technology
At present, common gas globular pressure-container is applied to store low-pressure gas, such as Chinese patent literature CN more
High pressure nitrogen spherical container disclosed in the preparation method of 105081705 A high pressure nitrogen spheric holders, including upper and lower two halves
The spherical shell of global shell make-up, is provided with air inlet and the gas outlet for efflux gas that supplied gas enters on spherical shell, with
Inject high pressure nitrogen realizing from air inlet to spherical shell, discharge high pressure nitrogen from gas outlet.But this gas globular pressure-container
In, the switch of gas outlet is typically by the Valve controlling of repeatable switch, so during Highpressure gas storage, at valve
Spool and valve seal position, it will usually the slow leakage of gases at high pressure occurs, although this slow leakage does not results in height
Calm the anger the rapid loss of body, but needs to gases at high pressure long time stored when, with the lengthening of period of storage, this slowly let out
The phenomenon that the gases at high pressure that dew is stored in still causing spherical shell run off in a large number so that gases at high pressure are with the lengthening of period of storage
The situation that pressure reduces and tolerance reduces occurs.
Utility model content
The purpose of this utility model is to provide a kind of deflation structure, it is intended to solve in prior art valve in off position under
The problem that gases at high pressure still can slowly be revealed.In addition, another object of the present utility model is to provide a kind of use this venting knot
The globular pressure-container of structure.
In order to realize object above, in the utility model, the technical scheme of deflation structure is as follows:
Deflation structure, including for blocking the air relief cock being arranged on the gas vent of vessel, air relief cock is provided with use
Open the weak structure of gas vent in breaking when being impacted or impact.
Weak structure is the annularly extension arranging on air relief cock or annularly spaced apart weak groove.
Air relief cock is provided with the blind hole of the inner chamber for connecting vessel, and described weak groove is in the periphery of air relief cock
On on the position of blind hole and/or the hole wall of blind hole, the pore wall thickness of the groove bottom part at annular groove for the air relief cock be less than its remaining part
The pore wall thickness dividing.
Air relief cock has the exposed parts for overhanging from gas vent, and described blind hole is prolonged along the overhanging direction of exposed parts
Stretch, and cecum and the described groove of blind hole are on the exposed parts of air relief cock.
Also include breaking the impact head of described weak structure for clashing into or impact air relief cock and for driving impact head
The driving means of movement.
In the utility model, the technical scheme of globular pressure-container is as follows:
Globular pressure-container, including spherical vessel, vessel is provided with the gas vent that supplied gas is released, venting
Closure on mouth is provided with air relief cock, and air relief cock is provided with the weak knot opening gas vent when being impacted or impact for breaking
Structure.
Weak structure is the annularly extension arranging on air relief cock or annularly spaced apart weak groove.
Air relief cock is provided with the blind hole of the inner chamber for connecting vessel, and described weak groove is in the periphery of air relief cock
On on the position of blind hole and/or the hole wall of blind hole, the pore wall thickness of the groove bottom part at annular groove for the air relief cock be less than its remaining part
The pore wall thickness dividing.
Air relief cock has the exposed parts for overhanging from gas vent, and described blind hole is prolonged along the overhanging direction of exposed parts
Stretch, and cecum and the described groove of blind hole are on the exposed parts of air relief cock.
Also include breaking the impact head of described weak structure for clashing into or impact air relief cock and for driving impact head
The driving means of movement.
In the utility model, air relief cock plays the effect of the gas vent of blocking container body, and puts vessel at needs
During gas, after only need to breaking the weak structure on air relief cock, air relief cock is opened from gas vent so that the gas in vessel
Can release, so in stored condition formula, air relief cock ensures that the gas vent of vessel is in integrated sealing state, is only breaking
In the case that bad formula is opened, just can open the gas vent of vessel, therefore this deflation structure solves valve in prior art
Descend the problem that gases at high pressure still can slowly be revealed in off position so that whole globular pressure-container has long-term storage and is difficult to
The advantage revealed.
