Fig. 3 is the three-dimensional exploded view that this utility model uses state.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As it is shown in figure 1, the core assembly of a kind of gas ratio valve, including spool 1 and rubber blanket 2.Described spool 1 includes the cylindrical part 11 of under shed, the flange portion 12 of the sphere curved surface around cylindrical part lower end, and the top board of cylindrical part 11 has through hole 13；
Also including an inner spool pillar 3, inner spool pillar 3 from top to bottom includes being positioned at the connecting portion 31 at top, shank portion 32, bar portion 33, the pedestal 34 of under shed hollow and the annular seat board 35 around pedestal；
Tubular face 21 that the outer circumference face of described rubber blanket 2 includes being positioned at bottom and superposed sphere curved surface portion 22；
Described pedestal 34 is positioned at the centre bore of rubber blanket 3, annular seat board 35 support rubber cushion 3, the connecting portion 31 of inner spool pillar 3 stretches out through spool 1, shank portion 32 is positioned at through hole 13, bar portion 33 is positioned at cylindrical part 11, the lower end in bar portion 33 and pedestal 34 support and coordinate, the upper surface of flange portion 12 and pedestal 34 and rubber blanket 2 against.
The sphere curved surface portion 22 of described flange portion 12 and described rubber blanket 2 adapts.Could also say that: the flange portion 12 of sphere curved surface and the sphere curved surface portion 22 of rubber blanket 2 constitute ball-crown body.
As in figure 2 it is shown, have buffer gap 4 between the top of the cylindrical part 11 of the upper end, bar portion 33 of described inner spool pillar 3 and spool 1.
As it is shown on figure 3, this reality have novel in use, the connecting portion of inner spool pillar 3 31 is sealed with locking piece 8 through supporting plate 5, voltage stabilizing sheet 6 and solenoid valve seat 7；The top braces supporting plate 5 of the cylindrical part 11 of spool 1.During assembling, harmless to rubber blanket 2.
Above-described is only preferred embodiments of the present utility model.It should be pointed out that, for the person of ordinary skill of the art, in the case of without departing from this utility model principle, it is also possible to make some improvement and modification, this is also considered as protection domain of the present utility model.
