The specific embodiment
(embodiment 1)
See Fig. 1-4, the spray 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 process.
Wherein, valve body 3 is male valve, and it comprises: adopt inner valve body 3-1 that the POM material processes and the outer valve 3-2 that is processed by PE (poly-vinyl) or PP weldability materials such as (polypropylene) that is socketed on the inner valve body 3-1 outside.
Inner valve body 3-1 can also be by PA (polyamide; Be commonly called as nylon), ABS (acrylonitrile-butadiene-styrene), PC (poly-meric 2-chlorobutadiene), HIPS (flame-proof highly anti-flush polyphenylacetylene), PET (polyethylene terephthalate), PPS (polyphenylene sulfide) or PEI (polyethyleneimine) material process these materials resistance good penetrability.
See Fig. 3 and 16, the cross section of outer valve 3-2 is rhombus or olive shape.The inwall of said outer valve 3-2 is provided with annular boss 3-21, and the bottom of inner valve body 3-1 and said annular boss 3-21 socket-connect, and the bottom of inner valve body 3-1 has hangnail 3-12.The upper surface of said annular boss 3-21 is provided with lower seal 6, is used to make vapor seal between the contact surface of bottom of upper surface and said inner valve body 3-1 of annular boss 3-21, thereby makes inner valve body 3-1 and outer valve 3-2 sealing socket.
See Figure 13, 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, thus 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 process, and its intensity is good, and air-tightness is good; So the better performances of its impermeabilisation,, valve body 3 and soft bag 9 needs that are tightly connected had mutually both been satisfied so these two kinds of materials are processed the interior outer valve of valve body 3 respectively; The requirement of having satisfied valve body 3 air-tightness and impermeabilisation is arranged, guaranteed relevant operating needs.
The port of said inner valve body 3-1 and outer valve 3-2 has flanging 3-11 and the 3-22 that is provided with up and down; 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 port and the seal closure 1.
