In order to overcome above-mentioned shortcoming, the purpose of this utility model is: design a kind of safe pressure relief device of family pressure cooker, be used to protect user's personal safety.
The safe pressure relief device of a kind of family pressure cooker of the utility model, consist predominantly of a pot cover, one pot of body, pot cover is provided with steam control valve and an air bleeding valve and a pressure relief device, and this pressure relief device is when pot inner pressure reaches predeterminable level, and promptly can pressurized forming perforation provides and let out except that pot inner pressure.This pressure relief device is that a conjugate foramen is set on pot cover, on conjugate foramen, fix a pressure release mounting, this pressure release mounting affixed conjugate foramen of sealing that can make progress from the pot cover bottom surface, this pressure release mounting keeps sealing state when being atmospheric pressure state in pot, when the pressure superpressure in the pot, the pressure release mounting punctures, and lets out except that pot inner pressure, avoids blast to hurt sb.'s feelings.This pressure release mounting also can be made a movable elastic force piston, one end is fixed on the pot cover, the other end is the abutting end of pot cover, piston is embedded in the conjugate foramen, when pot inner pressure was normal pressure, piston was blocked conjugate foramen, during the pot inner pressure superpressure, piston is raised by the air pressure pushing tow, and air pressure is let out by conjugate foramen and removed.
The utility model has the advantages that: simple in structure, safe in utilization.
The utility model has following accompanying drawing:
Fig. 1 is the schematic diagram of one of the utility model preferred embodiment.
Fig. 2 is the pressure release schematic diagram of one of the utility model preferred embodiment.
Fig. 3 is the schematic diagram of another preferred embodiment of the utility model.
Number in the figure is as follows:
10. pot cover 11. valve 12. air bleeding valves
13. conjugate foramen 14. pressure relief devices 15. packing rings
16. 20. pots of bodies of rivet, 141. pressure release mountings
142. rivet 143. pistons
Now lift a preferred embodiment and cooperate graphic being described as follows:
As shown in the figure, a kind of family pressure pressure cooker safe pressure relief device of the utility model, it is to comprise a pot cover (10) and one pot of body (20), simultaneously, this pot cover (10) top is provided with a steam control valve (11) and an air bleeding valve (12), an if pressure relief device (14), this pressure relief device (14) is provided with a conjugate foramen (13) in the predeterminated position of this pot cover (10), in this conjugate foramen (13), connect and establish a pressure release mounting (141), this pressure release mounting (141) is to be the gradually thin lamellar body of a periphery axial centre, this pressure release position system is located on this pressure release mounting (141), this pressure release mounting (141) is placed on pot cover (10) end side and is arranged in this conjugate foramen (13), and be exposed on the pot cover (10), simultaneously and establish and add packing ring (15) with rivet (16) and engage, prevent that according to this this pressure relief device (14) can so not drop in pot when being in no atmospheric pressure state in the pot.Certainly, also can be directly affixed with welding manner.
The pressure release mounting of above-mentioned embodiment is not have passage in principle, and both having made also is small passage.
Suppose pressure cooker in use, normal pressure is between 10～15 pounds (4.54～6.81 kilograms).When all air bleeding valves get clogged or burn improper excessive high temperature and the pressure of causing, the ability to bear that surpasses air bleeding valve, cause pressure in the pot gradually when normal 10～15 pounds begin to increase, traditional pressure cooker just can only lean on pot cover annex colloid to overlap ring breakage and lead pressure off.
Depending pot cover alone comes the pressure release meeting to produce danger greatly with pot colloid ring breakage of body thorough seal.So this case is designed, above-mentioned safe pressure relief device, system is set in when pressure and surpasses 15 pounds later on little by little, before also not surpassing 20 pounds, this safe pressure relief device will break automatically, and reach the effect of pressure release, and needn't allow pressure continue to increase when very big, just utilize the pot cover and the colloid cover ring breakage of pot body thorough seal to come pressure release.
