The specific embodiment
Below in conjunction with above-mentioned accompanying drawing embodiment the utility model is described in detail again.
Pressure cooker adjustable pressure limiting valve (referring to Fig. 1-11) is the steam pressure limiting pressure-regulating valve of weight superposing type, by the Different Weight group that third gear weight mutual superposition is formed, has third gear pressure cooker pressure at expulsion and regulates.
Valve seat 6 is tightly connected with pot cover 13, and the surface of pot cover is provided with the sign (not shown) that third gear is represented pressure at expulsion, to indicate the pressure at expulsion of the different foods of boiling.The valve seat center is steam vent I15, and spool 9 is sleeved on outside the valve seat, and interior shoulder is provided with jump ring 14, and valve and valve seat come off and cause damage when preventing that pot cover is reverse.When spool pushes in no external force, it is motionless to be in original position, the top of spool is by little pin 5 one that links to each other with knob head 1, knob head and spool have the steam vent II2 of 2 circumference uniform distributions, this steam vent II communicates with steam vent I, be provided with top 4 on the steam vent I of being fitted in by spring 3 pushing tows between knob head and the valve seat, top by jack-up during the pressure cooker pressure release, steam is discharged through steam vent II by steam vent I.
Knob head 1 below is provided with the knob 7 by 8 supportings of counterweight pad, and anti-skidding muscle 16 is arranged on the knob, identifies by the operating pressure on the arrow points pot cover and realizes regulating.The counterweight cushion cover is contained on the spool, spacing by the omoplate on the spool 18, but spool is provided with the weight of the controlled pressure pot pressure at expulsion that tangles several groups of weight stacks respectively, weight has last weight 10 and lower heavy punch 11, be processed with outside keyway 22 structures on the periphery of upper and lower weight, be provided with hanging structure between weight and the spool, this structure comprises that spool links up with 19 and 2 lower draw-bars 20 on 2 diametric 2 of periphery, can tangle weight and lower heavy punch respectively, and the diametric(al) of last weight and lower heavy punch endoporus have 2 corresponding fan-shaped extensions shoulders 23.The original position and the outside keyway 22 angle α of the fan-shaped extension shoulder of last weight 10
1Be counterclockwise 30 °; The original position and the outside keyway 22 angle α of the fan-shaped extension shoulder of lower heavy punch 11
2Be 30 ° of clockwise directions, the fan-shaped extension of upper and lower weight takes on 23 for diametric(al) is symmetrical arranged, its fan-shaped central angle alpha
3It is 60 °.
It between upper and lower weight and the knob relation of being in transmission connection of rotating synchronously, this is in transmission connection is the intercalation connection that slides over each other, be the protruding key 17 mutual slippery grafting of outside keyway 22 and knob endoporus on the upper and lower weight periphery, upper and lower weight is slided up and down along knob only, when knob was regulated, upper and lower weight was driven synchronous rotation.
The weight that this valve is formed weight superposing control pressure cooker pressure at expulsion has third gear, and first grade of weight formed (see figure 1) by knob head 1, spring 3, top 4, knob 7, counterweight pad 8, spool 9, jump ring 14; Second grade of weight by knob head 1, spring 3, top 4, knob 7, counterweight pad 8, spool 9, go up weight 10, jump ring 14 is formed (see figure 2); The third gear weight by knob head 1, spring 3, top 4, knob 7, counterweight pad 8, spool 9, go up weight 10, lower heavy punch 11, vertical pin 12, jump ring 14 and form (see figure 3).
The last weight of first grade of weight, lower heavy punch all fall, and promptly the spool hook does not all tangle, if push the knob head downwards with hand this moment, spring is compressed, whole valve body descends, and when treating that spool chassis is separated from vertical pin, knob is promptly rotatable, the rotation of knob drives upper and lower weight rotation, when the fan-shaped extension of last weight endoporus shoulder is tangled by going up on the spool, unclamp hand after, spring reset, to go up weight and mention, the weight that act on the summit this moment just equals second grade of weight weight.As continue to rotate knob, the fan-shaped extension shoulder of lower heavy punch endoporus is just tangled by the spool lower draw-bar, and holds up and go up weight, unclamp hand this moment after, upper and lower weight all is raised, this moment whole valve weight all be added in top on, form third gear weight weight.
Because valve in the course of the work, the exhaust of need often takeofing, sometimes also do irregular rotation, for the weight that prevents to be raised comes off, the spy is provided with circumferential locking mechanism between lower heavy punch and spool, this mechanism can be made up of with the vertical pin slotting slot 21 that matches the vertical pin 12 of close-fitting in lower heavy punch vertical pin hole 24 and spool chassis, and slot has 6, circumference uniform distribution.As long as valve is not that the people is for pressing down, vertical pin just is inserted in the slot of spool chassis all the time, the relation of being in transmission connection because of last weight, lower heavy punch and knob, can only slide up and down along knob, so knob can not produce irregular rotation when being subjected to the discharge of steam impact, upper and lower weight can not break away from articulating of spool hook yet and fall, guarantee that the pressure of setting up is constant, guarantee the needs of food boiling.
When this valve is done the pressure limiting adjusting, elder generation's push-turn key head, spring is compressed, after pressing to disengagement weight vertical pin, be that rotatable knob is done to regulate arbitrarily along contrary direction, forming upper and lower weight does not all have and tangles or go up that weight is tangled or go up the third gear pressure limiting pressure that weight, lower heavy punch are all tangled.
