Embodiment
The utility model below will combine accompanying drawing to do further to detail:
See also Fig. 1, shown in Figure 3, in the present embodiment, the unidirectional ventilation control gear of said diaphragm type; Comprise valve seat 1; Said valve seat 1 forms stepped through hole 11 along axis, is positioned at the stepped through hole 11 small-caliber ends air outlet hole joint 2 that is threaded, and is positioned at the stepped through hole 11 heavy caliber ends mangetic core assembly 3 that is threaded; Mangetic core assembly 3 inner chambers are provided with the one-way membrane member 34 that control gaseous flows to, the outer end of the mangetic core assembly 3 air source inlet joint 4 that is threaded.Offering the internal thread 42 that is threaded with the outside thread of mangetic core assembly 3 on the annular wall of said air source inlet joint 4 by some vents 41 of offering on the lid that is similar to bottle cap, the lid plane, lid inside forms.
See also shown in Figure 2ly, the dividing plate 32 that said mangetic core assembly 3 is radially offered by housing 31, housing 31 inner chamber middle-ends, the ring bodies 321 that dividing plate 32 is convexly equipped with towards air source inlet joint 4 directions along axis, ring bodies 321 inner chamber molding port ends are big and the pore 322 offered on dividing plate 32 plate bodys of T shape ladder hole 3211 that the bottom is little, ring bodies 321 peripheries, penetrate dividing plate ring bodies 321 from air outlet hole joint 2 one side valve chambeies and the one-way membrane sheet element 34 that extends to air source inlet joint 4 one side valve chambeies and wear ccontaining filtration sponge 33 in this spool is formed.Said housing 31 is by annular end cap 311; The tubular body 312 that this annular end cap 311 extends along axis towards both sides respectively; Tubular body 313; The annular groove 314 of moulding between tubular body 312 that matches with air source inlet joint 4 and the annular end cap 311; Be nested in the seal ring 315 in the annular groove 314; The protuberance 3131 of the middle part moulding of the outer surface of the tubular body 313 that matches with valve seat 1; The a pair of annular groove 3132 of these protuberance 3131 each moulding of both sides; 3133; The seal ring 316 that is sleeved in the protuberance 3131 outer end annular grooves 3133 is formed.
Said one-way membrane sheet element 34 upwards is convexly equipped with the cone 3421 that the film bar 342 of extension, shaft radial expansion that assembling caudacoria bar 342 is positioned at spool dividing plate ring bodies 321T type connecting part be used to be buckled on the T shape connecting part vertically by plate-like diaphragm 341, plate-like diaphragm 341 and forms from the center of circle.
Diaphragm type one-way valve be air-flow can only one direction flow and position control valve that can not reverse flow.Its working principle; When the pressure of valve seat 1 inner via hole 11 during greater than air source inlet joint 4 external air pressure, air overcomes plate-like diaphragm 341 small resistance and frictional force opens plate-like diaphragm 341, and source of the gas flows to outlet from inlet; When the pressure of valve seat inner via hole 11 during less than air source inlet joint 4 external air pressure; Under plate-like diaphragm 341 and spool mating face fit-state, spool is in closed condition, and source of the gas can't flow to air source inlet joint 4 outer ends from valve seat inner via hole 11.Because plate-like diaphragm 341 materials own belong to the soft silica gel class; Directly fit with the spool mating face; So the small variation of valve seat 1 inner cavity force value, plate-like diaphragm 341 can both sensitive opening or closures, guaranteed that air source inlet joint 4 air outside can flow in valve seat 1 chamber rapidly.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
