Description
Technical field
The utility model relates to a kind of limiting valve of pressure cooker, especially the improvement structure of limiting valve of pressure cooker.
Background technology
The present auto-electronic pressure cooker of selling on the market, be equipped with pressure limiting valve on its pot cover, general pressure limiting valve comprises valve body, and the jump ring, sleeve that place valve hole bottom are in the spool of valve hole bottom, and the thimble, pressure limiting valve seat and the anti-blocking seat that clog valve core through hole and pressurized come-up are formed.1), when pot inner pressure surpasses voltage limiting value there is following defective in the pressure limiting valve of this structure:, lose heart, its heating cooking process is in exhaust condition always at once, and food loses original nutrient contents and genuineness; 2), will realize that complete exhaust must take away valve body in the pot, its troublesome poeration more has plenty of, and when valve body was taken out, the steam in the pot was discharged in a large number quickly and scalded wrist easily, and child runs into just more dangerous.
The utility model content
It is not finish under the exhaust condition that the purpose of this utility model is to address the aforementioned drawbacks and a kind of cooking process rational in infrastructure, whole is provided, automaticity height, easy to operate and safe and reliable limiting valve of pressure cooker.
Technology solution of the present utility model is as follows:
A kind of improvement structure of limiting valve of pressure cooker, comprise valve body, place the jump ring of valve hole bottom, sleeve is in the spool of valve hole bottom, clog the thimble of valve core through hole, pressure limiting valve seat and anti-blocking seat are formed, valve body places in the cavity of a handle, be right after an end of thimble in the cavity of this handle, the other end of thimble stretches into valve hole and fills in the upper end of valve core through hole, the handle sleeve is in the pressure limiting valve seat, it inserts pressure limiting valve seat lower end partly and has several high breach and the low breach that is differential arrangement, is provided with in the pressure limiting valve seat and described high breach and the suitable projection of low breach.
The utility model can also adopt following technical measures to solve:
Described high breach and low breach are located on the opening perisporium of handle lower end.
Described high breach and low breach are curved, between two adjacent breach certain distance are arranged.
Described projection is the some projections that are horizontal protrusion in the pressure limiting valve seat, and projection is identical apart from the distance of pressure limiting valve seat bottom.
Described handle sleeve is printed on the sign that shows exhaust condition on the outer surface of pressure limiting valve seat.
Described jump ring is the sheet piece that is " Ω " shape, and spool passes the jump ring through hole and is clipped in this jump ring through hole.
There is recess the lower end of described valve hole, and jump ring is installed on the position of this recess.
Adopt the outstanding effect of the limiting valve of pressure cooker of said structure to be:
1), the pressure limiting valve of above-mentioned pressure cooker, because thimble is fastened on the handle inner chamber, the other end of thimble stretches into valve hole and fills in the upper end of valve core through hole, wherein, valve body places in the above-mentioned portable cavity, thimble and valve body portable and that cavity is interior connect together, its quality can be according to the voltage limiting value setting, so, the pressure limiting valve of this structure is not exhaust at normal cooking status, it is portable to be that pot inner pressure can not promote, and thimble still clogs valve core through hole, guarantees food original nutrient contents and genuineness.
2), the pressure limiting valve of the utility model pressure cooker, insert pressure limiting valve seat lower end partly at handle and have several high breach and the low breach that is differential arrangement, be provided with in the pressure limiting valve seat and described high breach and the suitable projection of low breach.When static, the high breach of handle lower end is bearing on the interior projection of pressure limiting valve seat, and thimble clogs spool upper end through hole, and pressure limiting valve is in air-tight state.Because handle and valve body are locked together, wait to cook and finish when needing exhaust, can stir handle gently and drive the valve body turn, make to catch up with and state the adjacent low breach of high breach and drop down onto above-mentioned projection in the pressure limiting valve seat, thimble leaves the spool bore certain distance, the steam in the pot is expelled to fully can opens pot cover.If pressure cooker needs to continue again pressurization, rotate handle again, the high breach adjacent with low breach dropped down onto on the projection in the pressure limiting valve seat again get final product.High breach on the handle is supported on projection in the pressure limiting valve seat and converts low breach to and be supported on projection in the pressure limiting valve seat, and promptly sealing state is converted to exhaust shape shape, can above-mentioned high breach, low breach and projection be set according to voltage limiting value.Its automaticity height, the user is easy to operate; Also avoided causing the accident of scalding wrist because of realizing that complete exhaust must take away valve body.

The specific embodiment
Extremely shown in Figure 2 as Fig. 1, a kind of improvement structure of limiting valve of pressure cooker, comprise valve body 1, place the jump ring 2 of valve body 1 via bottoms, sleeve is in the spool 3 of valve body 1 via bottoms, clog the thimble 4 of spool 3 through holes, pressure limiting valve seat 5 and anti-blocking seat 6 are formed, valve body 1 places in the cavity of a handle 7, be right after an end of thimble 4 in the cavity of this handle 7, the other end of thimble 4 stretches into valve body 1 through hole and fills in the upper end of spool 3 through holes, handle 7 sleeves are in pressure limiting valve seat 5, it inserts pressure limiting valve seat 5 lower end partly and has several high breach 8 and low breach 9 that are differential arrangement, is provided with the projection 10 suitable with described high breach 8 and low breach 9 in the pressure limiting valve seat 5.High breach 8 and low breach 9 are located on the opening perisporium of handle 7 lower ends.Wherein, high breach 8 and low breach 9 are curved, between adjacent two breach 8,9 certain distance are arranged.Described protruding 10 is the some projections that are horizontal protrusion in the pressure limiting valve seat 5, and projection is identical apart from the distance of pressure limiting valve seat 5 bottoms.
Above-mentioned handle 7 sleeves are printed on the sign 11 that shows exhaust condition on the outer surface of pressure limiting valve seat 5.Jump ring 2 is the sheet pieces that are " Ω " shape, and spool 3 passes jump ring 2 through holes and is clipped in these jump ring 2 through holes.There is recess 12 lower end of valve body 1 through hole, and jump ring 2 is installed on the position of this recess 12.There is screw thread described spool 3 lower ends, and the first end of this spiral shell successively passes a small washer 13, pressure limiting valve seat 5, pot cover 14 1 installing holes, sealing ring 15, Anti-stop cover 16 and nut 17, all screw tight on pot cover 14 with anti-blocking seat 6.
Operation principle: when static, the high breach 8 of handle 7 lower ends is bearing on the projection 10 in the pressure limiting valve seat 5, thimble 4 in handle 7 cavitys clogs spool 3 through holes, make pressure limiting valve be in air-tight state, stir handle 7, handle 7 drives valve bodies 1 turn, and the low breach 9 adjacent with this high breach 8 is threaded on the projection 12 in the pressure limiting valve seat 5, realizes the purpose of exhaust; If pressure cooker need continue pressurization, can continue to stir portable 7, low breach 9 adjacent high breach 8 are dropped down onto on the projection 12 in the pressure limiting valve seat 5 again, pressure limiting valve is in airtight, and pressure cooker can continue the heating pressurization.
