The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically technical scheme of the present invention.
Embodiment:
Relief valve of pressure cooker as shown in the figure mainly is to realize through knob lid 1, knob body 3, regulator board 4, pressure regulation valve body 19, pressuring adjusting valve base 16, pressing plate 7, spool 13, pressuring adjusting valve base mold insert 17, pressure regulator valve spring 20, elastic seal ring 18, seal receptacle 12, contiguous block 8.Knob body 3 is formed knob with knob lid 1, is stuck in through the draw-in groove on the knob body 33 in the bayonet socket of pressuring adjusting valve base, makes knob upper and lowerly not move, and can only rotate.One location projection 32 is arranged on the knob body 3, match, be used for positioning with link stopper 162 on the pressuring adjusting valve base (comprising contiguous block).On the knob lid 1 indication point is arranged, be used for indicating the position of transferring the files.Regulator board 4 is through being threaded on the knob body 3, and screw thread adopts left hand thread, handled easily, and regulator board has the backstay 41 that stretches out for 4 times, matches with two locating holes 71 on the pressing plate 7, guarantees when knob rotates, can not rotate, and regulator board 4 can only upper and lowerly move.Pressure regulation valve body 19 is enclosed within on the regulator board 4, in pressure regulation valve body 19 and the regulator board 4 pressure regulator valve spring 20 is housed.Spool 13 and pressure regulation valve body 19 are connected through draw-in groove, and spool 13 adopts beveled structures 131, when the work exhaust, increases compression area, can fully drain a pot interior elevated pressures, assurance pressure cooker operate as normal.Seal receptacle 12 directly is stuck on the pressure cooker cover 14.Pressuring adjusting valve base 16 is fastened on the pressure cooker cover 14 through contiguous block 8 usefulness clamping screws 11; Simultaneously can compress seal receptacle 12; Lock sealing circle 10 is housed on the clamping screw 11; Pressuring adjusting valve base 16 is distributed with two link stoppers 162 that are mutually 240 degree on (comprising contiguous block 8), guarantee that knob can only rotate back and forth between 2 grades at 0 grade; Gear numeral 161 is arranged on the pressuring adjusting valve base, represent neutral gear, low pressure shelves and high pressure shelves respectively with 0,1,2, the indication point that covers with knob is complementary.Pressuring adjusting valve base mold insert 17 is enclosed within outside the pressure regulation valve body 19, has pressing plate 7 to be screwed above, is pressed on the seal receptacle 12 with the arc surface structure below.When operate as normal, the rotation knob, knob body 3 drives regulator board 4 through internal thread 34 and moves up and down; Thereby change the decrement of pressure regulator valve spring 20; Make to act on the power generation size variation on the spool 13, therefore just changed the pressure size in the pot, reach the pressure regulation effect.When knob is screwed into indication point on the knob lid 1 during 0 grade-1 grade (not comprising 1 grade) at pressuring adjusting valve base, regulator board 4 is upwards mentioned pressure regulation valve body 19 in highest order through draw-in groove, makes spool 13 break away from pressuring adjusting valve base mold inserts 17, does not have pressure in the pot; When knob is screwed into indication point on the knob lid 1 and aims at 1 grade of pressuring adjusting valve base; Regulator board 4 is toward descending; Through the downward top pressure regulation of spring force valve body 19, make spool 13 sealing that matches with pressuring adjusting valve base mold insert 17, an operating pressure reaches low pressure shelves pressure (such as 50kPa) in the pot; Indication point when be screwed into knob lid 1 along with knob on is to 2 grades of pressuring adjusting valve base 16 time; Regulator board 4 continues toward descending; Thereby the spring operating distance between regulator board 4 and the pressure regulation valve body 19 constantly reduces, and the decrement that makes pressure regulator valve spring 20 produce constantly increases, and the spring force that acts on the spool 13 also can constantly increase; Guaranteed that a pot interior operating pressure can constantly raise; Thereby accomplished the pressure regulator valve continuous voltage regulating effect (put from 1 grade to 2 gears, such as according to designing requirement, can pressure regulation to any operating pressure value in 50kPa to 100kPa interval).Pressuring adjusting valve base mold insert 17, pressing plate 7 and 13 of spools are furnished with elastic seal ring, and water vapour flows to the knob place when preventing work, in order to avoid scald one's hand.Gas circuit diaphragm seal 15 is housed in the pressuring adjusting valve base, and pressuring adjusting valve base mold insert 17 is provided with the gas outlet, and exhaust guide effect when being used for work is avoided directly contacting with working of plastics, cleans easily, prevents to wear out.When pot inner pressure reached the operating pressure exhaust, steam can only be arranged downwards under the effect of elastic seal ring 18, through the exhaust of pressuring adjusting valve base gas outlet, under the leading according to gas circuit diaphragm seal 15, was discharged to 16 liang of side positions of pressuring adjusting valve base to steam then.Head part 5 and head part spring are installed in the aperture of pressuring adjusting valve base 16, and be fixing with pressing plate 7 above, matches with three grooves 31 on the knob body 3, can confirm that gear puts in place during the adjustment gear, reaches feel or the effect of sounding.
