The specific embodiment

(embodiment 1)

See Fig. 1-4, the male valve of present embodiment comprises: seal closure 1, spool 2 and valve body 3.Seal closure 1 adopts tin-plate and its surface through electroplating, and spool 2 adopts POM (polyformaldehyde) material to make.

Valve body 3 comprises: adopt the inner valve body 3-1 that the POM material makes and be placed in the outer valve 3-2 that is made by PE (polyethylene) material in the inner valve body 3-1 outside.

See Fig. 3, the cross section of outer valve 3-2 is rhombus or olive shape.The inwall of described outer valve 3-2 is provided with annular boss 3-21, and the bottom of inner valve body 3-1 and described annular boss 3-21 socket-connect, and the bottom of inner valve body 3-1 has hangnail 3-12.

The upper surface of described annular boss 3-21 is provided with lower seal 6, is used to make vapor seal between the contact surface of bottom of the upper surface of annular boss 3-21 and described inner valve body 3-1, thereby makes vapor seal between the contact surface of inner valve body 3-1 and outer valve 3-2.

See Figure 11, during use, the lateral surface of outer valve 3-2 links to each other with the inlet seal of soft bag 9, because outer valve 3-2 is the PE material, so conveniently valve body 3 and soft bag 9 are connected and sealed, but the PE material has penetrablility to gas, and inner valve body 3-1 adopts the POM material to make, its intensity is good, and air-tightness is good, so the better performances of its impermeabilisation, so these two kinds of materials are made the interior outer valve of valve body 3 respectively, both satisfy valve body 3 and soft bag 9 needs that are tightly connected mutually, the requirement of having satisfied valve body 3 air-tightness and impermeabilisation had been arranged, guaranteed relevant operating needs.

The upper port of described inner valve body 3-1 and outer valve 3-2 has the flanging 3-11 and the 3-22 of upper and lower settings; Be fixed with seal closure 1 on this conduplication side 3-11 and the 3-22, be provided with back seal circle 4 between the flanging 3-11 of inner valve body 3-1 upper port and the seal closure 1; Be provided with spool 2 in the valve body chamber 3-10 of inner valve body 3-1, spool 2 bottoms are provided with spring 5, and the upper end 2-1 of spool 2 is a hollow cavity, and this upper end 2-1 passes seal closure 1; The neck 2-2 of the annular groove shape of spool 2 is provided with 2 of connecting with described hollow cavity (among other embodiment, can be 1,3, even more) through hole 2-20; Described back seal circle 4 is placed in the neck 2-2 of described spool 2, and back seal circle 4 makes vapor seal between the valve body chamber 3-10 of described through hole 2-20 and inner valve body 3-1.The sidewall of the neck below of described spool 2 is provided with 6 groove 2-3, is provided with exterior seal ring 8 in the arc groove of seal closure 1 outer peripheral edges.

When the spray valve of present embodiment is located on the soft bag 9 shown in Figure 11, if press the upper end 2-1 of bottom spool 2, then described back seal circle 4 breaks away from each other with the neck 2-2 of described spool 2, communicate between the valve body chamber 3-10 of described through hole 2-20 and inner valve body 3-1, at this moment, owing to the air pressure in the valve body chamber 3-10 (being soft bag 9) of inner valve body 3-1 is higher, so the liquid in the soft bag 9 sprays through the through hole 2-20 of each groove 2-3, spool neck 2-2 and the upper end 2-1 of spool 2 successively.

See Figure 11 and 12, it is leg-of-mutton 2 annular relief 3-14 that the upper surface of inner valve body 3-1 is provided with the cross section, with the upper surface of guaranteeing inner valve body 3-1 and the air-tightness of described back seal circle 4.
