Abstract

The utility model provides an aerating valve, including valve body, rubber sleeve and valve rod, a rubber sleeve pot head is on the valve body, and the interface of giving vent to anger is opened to one end, and the inside axial of valve body has the tertiary cascaded cavity of an intercommunication inlet end and the end of giving vent to anger, and the internal diameter of cavity is proper to reducing in proper order to giving vent to anger along the inlet end, forms inlet end cavity, middle cavity and the end cavity of giving vent to anger respectively, the valve rod afterbody passes through the sealing washer setting and in middle cavity upper end, is equipped with the spring in the end cavity of giving vent to anger, and spring one end is even on the end cavity inner wall of giving vent to anger, and the locator card is passed through even on the valve rod to one end, and under the effect of spring or pressure, the valve rod can reciprocate about or skewly along the predetermined trajectory of the parallel direction of cavity, and the valve rod is worn out from the end cavity of giving vent to anger, wears out the part and is wrapped up in the rubber sleeve. The aerating valve gas tightness is better, can use repeatedly many times.

Description

A kind of charge valve

Technical field

This utility model relates to a kind of aerating device, particularly to a kind of charge valve.

Background technology

Charge valve used in the market is mainly charge valve as disclosed in CN202023958U.This charge valve is in use, helium interface and gas tube are connected on helium air accumulator, the inflation inlet needing inflatable balloon is enclosed within the charging connector on rubber sleeve, valve rod is stirred by rubber sleeve, the deviation of valve rod so that helium can enter in balloon in valve body, after the helium in balloon is substituted the bad for the good, unclamping hands, valve rod can realize closing valve body by return spring.Use this charge valve can control the release of helium, but owing to valve rod is fixed on valve inner by spring and locator card, make to offset about the action that valve rod can only whip, using after a period of time owing to the abrasion of the parts such as spring sealed circle can cause the air-tightness of charge valve bad, inflation when, gas leak phenomenon can occur.

Utility model content

Technical problem to be solved in the utility model is for the deficiencies in the prior art, it is provided that the charge valve that a kind of Novel air tight is good.

To achieve these goals, following technical scheme is proposed:

A kind of charge valve, including valve body, rubber sleeve and valve rod, rubber sleeve one end is enclosed within valve body, one end has interface of giving vent to anger, it is characterized in that, valve inner axially has a connection inlet end and three grades of staged cavitys of outlet side, and the internal diameter of cavity is sequentially reduced along inlet end to direction, outlet side, forms inlet end cavity, middle chamber and outlet side cavity respectively；Described valve rod afterbody is arranged on middle chamber upper end by sealing ring, it is provided with spring in the cavity of outlet side, spring one end is connected on the cavity inner wall of outlet side, one end is connected on valve rod by locator card, under the effect of spring or pressure, described valve rod can move up and down or left and right deviation along the planned orbit of the parallel direction of cavity, and valve rod passes from outlet side cavity, passes part and is wrapped in rubber sleeve.

Further, described outlet side cavity has a horn opening.

Further, it is provided with sealing ring and packing ring between described inlet end cavity and middle chamber.

Compared with prior art, the beneficial effects of the utility model are: charge valve air-tightness is preferable, can be reused several times.

Accompanying drawing explanation

Fig. 1 is sectional view of the present utility model.

Detailed description of the invention

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.

A kind of charge valve, including valve body 3, rubber sleeve 2 and valve rod 1, rubber sleeve 2 one end is enclosed within valve body 3, one end has interface of giving vent to anger, described valve body 3 is internal axially a connection inlet end and three grades of staged cavitys of outlet side, the internal diameter of cavity is sequentially reduced along inlet end to direction, outlet side, forms inlet end cavity, middle chamber and outlet side cavity respectively；Described valve rod afterbody is arranged on middle chamber upper end by sealing ring 4, spring 5 it is provided with in the cavity of outlet side, spring 5 one end is connected on the cavity inner wall of outlet side, one end is connected on valve rod by locator card 6, under the effect of spring or pressure, valve rod 1 can move up and down or left and right deviation 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.Described outlet side cavity has a horn opening.Sealing ring 8 and packing ring 7 it is provided with between described inlet end cavity and middle chamber.

When using this utility model, inflatable interface is connected with gas filling bottle, again object to be inflated such as balloon etc. is inserted in rubber sleeve 2, by fiddling with rubber sleeve 2, valve rod 1 is deviateed, move up and down in valve cavity or left and right deviation, gas can enter balloon by valve body 3, stops when balloon is full of fiddling with, and can stop inflation.

This utility model charge valve, makes the most easy to use, and air-tightness is good, can use repeatedly.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
