Between the gas charging valve and bleed valve of described one-way valve in valve body, it is made up of nonreturn valve core and unidirectional valve pocket, valve pocket is an enclosed cavity, the one end is thin neck, and it has passage to be connected with gas charging valve, has passage to be connected with bleed valve at the large-diameter portion branch of valve pocket, nonreturn valve core is made of the conical surface flange of valve rod and close one end, stem diameter is less than described thin neck, and the external diameter of conical surface flange is greater than thin neck, and its conical surface partly extends to big footpath cavity in thin neck; On the pairing valve body of the other end of valve rod, a pit is arranged.
It is that an independent plug is connected with valve seal that described unidirectional valve pocket has an end of pit.
The utility model is an one with the Air filling and discharging valves collection, simplifies the structure, and has reduced cost of production, and it is also convenient to install.Just can utilize human body to trigger its inflation valve rod by simple trigger mechanism on the seat, realize inflation automatically, and human body can make bleed valve open after disseating, automatic deflation.This valve can be installed in below the seat, and the integrity that does not disfeature makes the seat more attractive in appearance.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model;
Fig. 2 is the schematic representation of a kind of application mode of the utility model.
Embodiment
Referring to Fig. 1, structure of the present utility model is to make gas charging valve A, a bleed valve B and an one-way valve C in valve body 11, the structure of gas charging valve A and bleed valve B is identical, they are by being positioned at described valve body 11, two valve pockets 12 that are parallel to each other, spool 7, valve rod 9, Returnning spring 6 formations, and the equal connecting tube joint 1 of the same end of two valve pockets 12 is respectively as inflation interface D and air bag interface E.The other end of valve pocket 12 has two-stage reducing step, the outer end of valve rod 9 passes the reducing of outermost, there is outward flange to be positioned on the second level reducing step at these valve rod 9 inner side faces, valve rod 9 the inners are connected with spool 7, outward flange 71 is arranged on spool 7 side faces and be enclosed within the valve pad 8 that it has valve rod 9 one sides, between pipe joint 1 the inner of the spool flange 71 and valve pocket 12 the other ends, place Returnning spring 6.Another valve port of bleed valve B connects air vent F.
Between the gas charging valve A and bleed valve B of described one-way valve C in valve body 11, it is by nonreturn valve core 5, unidirectional valve pocket 13, valve pocket 13 is an enclosed cavity, its bottom is sealed with a plug 3, its outlet end is thin neck 131, it has passage 15 to be connected with gas charging valve A, large-diameter portion branch at valve pocket 13 has passage 14 to be connected with bleed valve B, nonreturn valve core 5 is made of the conical surface flange 52 of valve rod 51 and close one end, the diameter of valve rod 51 is less than described thin neck 131, the external diameter of conical surface flange 52 is greater than thin neck 131, and its conical surface extends to big footpath cavity part in thin neck 131; The other end of valve rod 51 a pit 31 is arranged on the right plug 3.
