Abstract
The utility model discloses a safety-relief device for the pressure pot, comprising a pressure adjusting bolt, an upper valve body and a lower valve body of the exhaust valve arranged on the cover of pressure pot, which is characterized in that a multi-claw circlip is arranged to fasten the inner end surface of the upper valve body in the exhaust valve through the pressure adjusting bolt, a piston with prism is arranged on the inner area of the exhaust valve, the claw mouth of the multi-claw circlip is sliding connected to the piston prism, the multi-claw circlip is fastened on the low inner end surface of the upper valve body in the exhaust valve through the pressure adjusting bolt, the claw mouth of the multi-claw circlip is sliding connected with the prism of the piston, the claw mouth reaches the side edge under the pressure of the rising air, the o sealing position of the piston is disengaged from the lower valve body, the exhaust valve discharges outside, when the exhausted air reaches the safe pressure, the piston is automatically sealed to ensure pressure not rise up. The utility model has the advantages of simple, safe and beautiful structure.
Description
Technical field:
The utility model relates to the pressure cooker field, more particularly relates to the safe pressure relief device of pressure cooker.
Background technology:
At present, pressure cooker exquisite appearance, energy savings, high efficiency are subjected to liking of numerous people.General pressure cooker cooking, internal pressure rises to when exceeding set pressure, and safety valve can be opened, and gas is discharged from steam vent, and when pot internal gas pressure descended, safety valve can cut out automatically.Safety valve was once lost efficacy the danger that is easy to blast.As application number is 00202187, the applying date is on January 11st, 2000, and denomination of invention is a pressure cooker anti-explosion exhaust valve, is made up of aiutage, nut, push rod, filter air chamber, spring and bearing plate, it is flexible to it is characterized in that utilizing pressure cooker pressure to adjust push rod, reaches explosion-proof purpose.When pot inner pressure exceeded design load, bearing plate overcame spring and heavy valve resistance at once, made push rod push heavy valve exhaust open.Dangerous situation is got rid of, and pressure reduces, and in the push rod withdrawal exhaust duct, makes in the pot to keep-up pressure.This patent anti-explosion exhaust valve repeats sealing, and operating safety factor is low, complex structure.
The utility model content:
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only easy to use, the pressure cooker safe pressure relief device that safety coefficient is also high.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of pressure cooker safe pressure relief device, by regulator bolts and be installed in exhaust upper valve body that pressure cooker pot covers, valve body constitutes down, have steam vent on the upper valve body, the lower end of following valve body is provided with air admission hole, it is characterized in that: be provided with the pawl jump ring of hanging by regulator bolts at air bleeding valve upper valve body inner face, the piston on top band prismatic or spherical inclined-plane is installed in the top air bleeding valve of air admission hole, and the pawl mouth of pawl jump ring and the inclined-plane of piston are slidingly connected.
As further specifying of such scheme, described air bleeding valve is arranged on the middle part of pressure cooker pot lid, also can be installed in other correct position, regulates the middle position that bolt is positioned at valve body.
Following valve body covers the inner face contact position with pot, the piston side is equipped with O-ring seals respectively with following valve body contact position.
The pawl card number of described pawl jump ring is two pawls or more than two pawls.
Its top of piston on band inclined-plane, described top is cone or spheroid.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the multijaw jump ring is hung at air bleeding valve upper valve body inner face by regulator bolts, the pawl mouth of multijaw jump ring and piston prismatic inclined-plane are slidingly connected, after pressure release finishes, piston can not repeat sealing voluntarily, guarantee that pressure can not rise, compare with first modern technology, have more advantage simple in structure, safe, attractive in appearance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals: 1, pot covers 2, descends valve body 3, upper valve body 4, steam vent 5, regulator bolts 6, O RunddichtringO 7, pawl jump ring 8, air bleeding valve 9, piston 10, air admission hole 11, O RunddichtringO 12, inner bag 13, stay-warm case 14, sealing ring
The specific embodiment
As shown in Figure 1, of the present utility model is example with voltage power (pot) pot, voltage power (pot) pot is outer to be stay-warm case 13, in inner bag 12 is arranged, this pressure cooker safe pressure relief device is arranged on the pot cover 1, lid 1 and 12 of inner bags are provided with sealing ring 14, pressure relief device is by regulator bolts 5 and be installed in the exhaust upper valve body 3 that pressure cooker pot covers, following valve body 2 constitutes, two pawls or multijaw jump ring 7 are set are installed in air bleeding valve upper valve body 3 inner faces by regulator bolts 5, the piston 9 on band prismatic inclined-plane, top is installed in the inside of air bleeding valve 8, and the pawl mouth of multijaw jump ring 7 and piston 9 prismatic inclined-planes are slidingly connected.Following valve body 2 covers the inner face contact position with pot, piston 9 sides are equipped with O-ring seals 6 and 11 respectively with following valve body 2 contact positions, and air admission hole 10 is positioned at the lower end of valve body 2 down, has steam vent 4 on the upper valve body 3.
Described air bleeding valve 8 is arranged on pressure cooker pot and covers 1 middle part, also can be installed on other suitable position, and regulator bolts 5 is positioned at the middle position of upper valve body 3.
In the use, liquid boiling in pot, when air pressure inside rose to set pressure, Pneumatic pipe cleaner safety valve air admission hole up pushed away piston 9, after the corner angle on prismatic inclined-plane rose to the pawl mouth A point of multijaw jump ring sheet, the centripetal tension of pawl jump ring will be past to drawing the prismatic cylinder of piston 9.The O shape seal valve position of piston 9 has just broken away from time valve body as a result.Compressed Gas in pot is at once by air admission hole 10, steam vent 5 outside pressure releases.Pressure release finishes, and piston 9 can be from movable sealing.
