Accompanying drawing explanation
Fig. 1 is the part cross-sectional plane schematic diagram that aqueous vapor of the present invention is controlled an embodiment of main valve;
Fig. 2 is the floor map of another angle of an aqueous vapor of the present invention embodiment of controlling main valve.
Embodiment
Below in conjunction with each mode of execution shown in the drawings, the present invention is described in detail; but should be noted that; these mode of executions are not limitation of the present invention; those of ordinary skills are according to these mode of execution institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection scope of the present invention.
As shown in Figure 1 and Figure 2, aqueous vapor of the present invention is controlled main valve 100, comprising: valve body 10, the second cavity 102 that be provided with the first cavity 101 in described valve body 10, parallels with described the first cavity 101.
Wherein, described the first cavity 101 comprises the first chamber 1011 and the second chamber 1012, the internal diameter of described the first chamber 1011 is greater than the internal diameter of described the second chamber 1012, in described the second chamber 1012, be provided with the first spool 20, described the first spool 20 two ends are provided with the seal ring fitting with described the second chamber 1012 inwalls.Preferably, sealing circle is O RunddichtringO.Between the sealed at both ends circle of described the first spool 20, be provided with the first outlet nozzle 30 being connected with described the second chamber 1012, in present embodiment, this first outlet nozzle 30 is perpendicular to described valve body 10.When described the first spool 20 is positioned at initial position, the path between the first chamber 1011 and the second chamber 1012 is by the first spool 20 sealings, and the first outlet nozzle 30 airless spray.
Similarly, described the second cavity (not shown) comprises the 3rd chamber (not shown) and (not shown), the internal diameter of described the 3rd chamber is greater than the internal diameter of described the 4th chamber, in described the 4th chamber, be provided with the second spool (not shown), described the second spool two ends are provided with the seal ring fitting with described the 4th chamber inner wall, are provided with the second outlet nozzle 50 being connected with described the 4th chamber between the sealed at both ends circle of described the second spool.In present embodiment, this second outlet nozzle 50 is perpendicular to described valve body 10.When described the second spool is positioned at initial position, the path between the 3rd chamber and the 4th chamber is sealed by the second spool, the second outlet nozzle 50 airless ejections.Described the 3rd chamber is also connected with one the 3rd outlet nozzle 60.
