Preferably, the diameter of described the first cavity is less than the diameter of described the second cavity, and the diameter of described the 3rd cavity is less than the diameter of described the second cavity, and the diameter of described the 4th cavity is greater than the diameter of described the 3rd cavity.
Preferably, described the 4th cavity is positioned among described prolongation guard circle.
Preferably, the top of described main body is also provided with a brace being connected for the courage body with inner bag, and the diameter of described brace is greater than the outer circumference diameter of described main body.
Preferably, described through hole is three.
The inner bag that a kind of sport balls of the present utility model is used, comprises courage body and is connected to the valve on courage body, described valve is aforesaid valve.
Compared with prior art; the utility model inner bag valve; to consider under all general ball scopes that to inflate by air tube length be 30mm～35mm; one prolongation guard circle is set; and retain the aeration modes of existing valve; when air tube inserts inflation, extending under the effect of guard circle, can avoid touching the inwall of inner bag and inner bag is punctured.
Further, the position of locating near gas outlet at prolongation guard circle is provided with through hole, by this through hole, can make air can smoothness fill with rapidly inner bag when injecting, and reaches effect and the efficiency identical with traditional type vapour lock.
Valve of the present utility model, while inflating, air tube can not touch wall of inner container under the prolongation guard circle of valve coated, all there will not be the situation that punctures inner bag when making inner bag in inflation or cooling down;
In addition, because the entire length of valve is than traditional length, the probability that the air of inner bag inside is overflowed via valve reduces, and improves the air-tightness of inner bag.
Accompanying drawing explanation
Fig. 1 is the overall structure figure of the inner bag valve embodiment that uses of the utility model sport balls;
Fig. 2 is the profile of inner bag valve shell in Fig. 1.
The specific embodiment
For making the technical solution of the utility model clearer, below in conjunction with accompanying drawing, by specific embodiment, the utility model is elaborated.
Basic conception of the present utility model is; at valve shell, one prolongation guard circle is set, when air tube inserts inflation, in the end of air tube can being coated on; at this, extend under the effect of guard circle, can make air tube avoid touching the inwall of inner bag and inner bag is punctured.
Embodiment mono-
Referring to Fig. 1, Fig. 2, the inner bag valve in the present embodiment comprises inner core 1, shell 2, and inner core 1 is arranged in the cavity of shell 2.
Shell 2 comprises brace 21, main body 22 and prolongation guard circle 23, and this prolongation guard circle 23 is provided with three through holes 24, this through hole 24 and the bottom margin conducting that extends guard circle 23.Three through holes 24 are along extending circumferentially evenly arranging of guard circle 23, and the shape of three through holes 24, size are all identical.The outer circumference diameter of brace 21 is greater than the outer circumference diameter of main body 22.
Shell 2 is provided with the cavity of up/down perforation, and this cavity comprises the first cavity 2a, the second cavity 2b, the 3rd cavity 2c, the 4th cavity 2d from top to bottom.Wherein, the diameter of the first cavity 2a is less than the diameter of the second cavity 2b, and the diameter of the 3rd cavity 2c is less than the diameter of the second cavity 2b, and the diameter of the 4th cavity 2d is greater than the diameter of the 3rd cavity 2c.The 4th cavity 2d is arranged in and extends guard circle 23.The top of the 4th cavity 2d is cone cylinder body shape, and bottom is cylindrical.
