Embodiment:

With reference to Fig. 4, be shaped on planar slot in the valve body 6, groove has backed down arc surface pit 6.2 and vent hole 15, and the trough rim inboard is shaped on a restriction protrusion 6.1.

With reference to Fig. 5, Fig. 6, cover plate 13 interior edge faces have arc surface pit 13.2, are integral when L shaped fixed touching plate 11 and cover plate 13 injection mouldings, and fixed touching plate 11 upper ends constitute the contact 11.1 that closes, divides with movable touching plate 12.

With reference to Fig. 7, Fig. 8, Fig. 9, elastic reset slide 7 middle parts have rectangle fenestra 7.2, and the rear end has the draw-in groove 7.5 that links with pull bar 3 tops; Front end is made plane groove, sets the movable touching plate 12 that elastic spring is made in the groove; The smooth upper-end surface 7.1 of the slightly protruding one-tenth of top front, the front portion, upper-end surface is shaped on axial notch 7.4, and this groove is positioned under the vent hole 15 place axis; One outside, slide 7 upper ends is along being shaped on one section groove 7.3, for cooperating the stroke stop bit mechanism that constitutes slide 7 with valve body 6 interior restriction protrusion 6.1.

With reference to Fig. 1, Fig. 2, Fig. 3, the exhaust fitting 9 that is communicated with air cushion is threaded with valve body 6 by O RunddichtringO 10, valve body 6 with fasten in opposite directions by screw 16 and cover plate 13.Be communicated with by vent hole 15 in the valve body 6 with between the joint 9.Air valve handle 1 is tightened together with air valve pull bar 3 by interior hexagonal tight fixed bolt 2, air valve pull bar 3 tops are passed the center hole of valve body 6 and are linked with the draw-in groove 7.5 of air valve slide 7, slide 7 is loaded in valve body 6 and cover plate 13 buckling bodies, and is slidingly matched with the valve body planar slot.Bench port is expanded in vent hole 15 lower ends of valve body 6, setting-in O-ring seals 8 in mouthful.Valve body 6 respectively is shaped on relative arc surface pit 6.2,13.2 with cover plate 13, and arc surface pit 6.2,13.2 and therebetween rectangle fenestra 7.2 are formed the cylindrical cavity volume of ccontaining helical spring 14.

When being installed, this hand control valve is fixed product with nut 4 and internal tooth packing ring 5.

Working procedure:

Helical spring 14 places in the cylindrical cavity volume that arc surface pit 6.2,13.2 and therebetween rectangle fenestra 7.2 form, and hole, the two ends wall of arc surface pit 6.2,13.2 constitutes the pedestal of helical spring 14.

Inflation: press lower air valve handle 1, helical spring 14 is subjected to down pressure extrusion-deformation, and air valve slide 7 is descending with handle 1, and movable touching plate 12 contacts energising to lower slider and with the air valve fixed touching plate 11 that is embedded in 13 li of cover plates, make air pump motor energising entry into service, inflate to shock-absorption air bag; Simultaneously 7.1 extruding O RunddichtringO 8 lower end surfaces, air valve slide upper-end surface and block vent hole 15 on the valve body 6 are closed valve.When the external force effect disappearance that acts on the air valve handle 1, helical spring 14 actions on the slide 7 reset, and make slide 7 reply original states, because vent hole 15 is still blocked in slide upper-end surface 7.1, valve still is in closed condition.

Venting: air valve handle 1 is under the effect of pulling force, the helical spring 14 that resets is subjected to external force extrusion-deformation upwards, slide 7 upwards slides, the axial notch 7.4 of slide 7 upper-end surfaces 7.1 is under the seal ring 8 of air valve body 6, sealing disappears, and the gas in the air bag carries out exhaust decompression by the vent hole on gas-tpe fitting 9 and the air valve body 6 15.Release handle 1 when exhaust is finished, and external force disappears, and helical spring 14 actions that reset on the air valve slide 7 reset, and make air valve slide 7 reply original state, and vent hole 15 are blocked again with valve closure in air valve slide upper-end surface 7.1, finishes whole work period.
