Preferably, rubber sleeve 2 both ends open width differs, and the wide one end of its opening is airtight with the outlet side of valve body 3 to be connected.
Preferably, the external diameter of packing ring 7 is more than middle chamber radius and the internal diameter less than or equal to inlet end cavity.
Preferably, the locator card of valve rod 1 and the external diameter both sealing ring 8 are all higher than the internal diameter of outlet side cavity, but the external diameter of locator card is less than the external diameter of sealing ring 8.
Preferably, valve rod 1 passes part from outlet side cavity, is cased with an Olivary head 6, and Olivary head 6 is wrapped up by rubber sleeve 2.
Preferably, valve rod 1 material is that 20# is firm.
Preferably, the material of rubber sleeve the 2nd, sealing ring 4 and sealing ring 8 is chloropharin.
Preferably, the material of valve body 3 and Olivary head 6 is reinforced polyamide 1010.
Preferably, spring 5 material is 65Mn-GB699-88.
Preferably, packing ring 7 material is HPb59-1.
Preferably, three grades of staged cavitys be processed by mould on valve body 3 one-time formed, and three grades of staged cavitys are respectively inlet end cavity, middle chamber and outlet side cavity, the cavity internal diameter of three, it is followed successively by from big to small: inlet end cavity, middle chamber and outlet side cavity.
Preferably, locator card plays the effect of control valve rod 1 position, and its manufacture craft can be valve rod 1 and locating ring secondary operations is bonded, it is also possible to be mould one-shot forming.
Preferably, valve rod 1 passes part from outlet side cavity, can add the termination of a near-spherical, for example: spherical, olive-shaped, the termination point casing of near-spherical passes part at valve rod 1 from outlet side cavity, and adding behind termination can the preferably inlet of Non-follow control gas and admission velocity.
The beneficial effects of the utility model: practical, production cost is low, is conveniently connected to gasing tank, and Non-follow control gas passes part from outlet side cavity, and is punched into gas in balloon, easy to use.

Detailed description of the invention
A kind of helium gas charging valve, including valve body the 3rd, valve rod 1 and rubber sleeve 2, described rubber sleeve 2 both ends open, one end is connected with the outlet side of valve body 3；There are three grades of staged cavitys of a connection inlet end and outlet side at described valve body 3 center, and the radius of cavity successively decreases along inlet end successively to outlet side direction, forms inlet end cavity, middle chamber and outlet side cavity respectively；Described placed sealing ring 4 and packing ring 7 in inlet end and middle chamber joint；Being sequentially placed return spring 5 and valve rod 1 in described middle chamber, valve rod 1 is provided with locator card, and return spring 5 is connected with valve rod 1 locator card, is provided with sealing ring 8 at the locator card of valve rod 1 and the interface of outlet side cavity；Described valve rod 1 runs through middle chamber and outlet side cavity, under the effect of spring 5 or pressure, can move up and down along the planned orbit of the parallel direction of cavity, and valve rod 1 passes from outlet side cavity, passes part and is wrapped in rubber sleeve 2.
When using the utility model, only first need to be connected to the inlet end of valve body 3 of the present utility model on helium air accumulator, the inflation inlet needing inflatable balloon is enclosed within rubber sleeve 2 slot, pressed the Olivary head 6 of valve rod 1 by rubber sleeve 2, move in the horizontal rail direction making the cavity along valve body 3 for the Olivary head 6, extrusion spring 5 makes gap occur at locator card and sealing ring 8, make the helium can be from the inlet end cavity of valve body 3, enter in balloon through middle chamber and outlet side cavity, after the helium in balloon is substituted the bad for the good, unclamp Olivary head 6 on valve rod 1, sealing ring can play the effect preventing gas from leaking, valve rod 1 can make locator card and the space closure of sealing ring 8 by spring 5, thus realize that valve body 3 is closed, inflation finishes, thus realize the purpose of this utility model.
The simple change of those ordinary skill in the art and replacement, be all protection domain of the present utility model.
