Abstract
The utility model relates to a safety valve for a high-pressure cooker and aims to solve the problem of inconvenient and unsafe steam releasing operation of the prior safety valve for the high-pressure cooker. The safety valve for the high-pressure cooker comprises a seat hole formed on a base and a valve plug; a sealing rubber ring is arranged on the seat hole, the upper part thereof is clamped on the inner wall of the lower part of the seat hole; an annular groove is formed at the lower part of the sealing rubber ring; the valve plug is clamped in the sealing rubber ring; a blocking disc is arranged at the bottom part of the valve plug; and an annular part matched with the blocking disc is arranged on the sealing rubber ring. When the safety valve is installed, an installation hole is formed in the corresponding position of a cooker cover, and the annular groove at the lower part of the sealing rubber ring is clamped on the installation hole. When the safety valve is in use, steam can be released only through pressing the safety valve by using a pair of chopsticks. The safety valve for the high-pressure cooker has the advantages of convenient pressure release, simple structure, safety and reliability and can be widely applied to various high-pressure boilers.
Description
Technical field
The present invention relates to a kind of pressure cooker safety valve.
Background technology
In daily life, the application of pressure cooker is very general.Pot cover for existing pressure cooker has been provided with a bleeder pipe, be equipped with a pressure limiting bonnet on this bleeder pipe, this pressure limiting bonnet bottom centre has blind hole, and the blind hole center is provided with taper gas shutoff plug, has some steam vents of letting out on the pressure limiting bonnet side wall around the taper gas shutoff plug.Taper is stifled to be pressed on the bleeder pipe, and during use, when pressure cooker pressure reached certain numerical value, HCS played the pressure limiting valve crown, and safety is guaranteed in the pressure release of pressure limiting valve take-off steam bleeding.
This safety valve structure is simple, during steam bleeding, the pressure limiting bonnet is picked up a bit gently, and progressively steam bleeding is reduced to normal pressure until the pressure cooker internal pressure, just can open pot cover, inconvenient operation, and also dangerous.
Utility model
The technical problem to be solved in the present invention is the above-mentioned defective that how to overcome prior art, and a kind of pressure cooker is provided.
For solving the problems of the technologies described above, this pressure cooker comprises seat hole and the valve plug that is opened on the pedestal with safety valve, this hole is provided with O-ring seal, sealing cushion rubber top is stuck on the inwall of described seat bottom, hole, the O-ring seal bottom has annular groove, described valve fork clip is in O-ring seal, and valve plug bottom is provided with stifled dish, and described O-ring seal is provided with the ring portion of joining with described stifled dish.During installation, on the relevant position of pot cover, open installing hole, the annular groove of O-ring seal bottom is stuck on the word dress hole.In the use, when needing steam bleeding,, get final product steam bleeding as long as press with chopsticks.
As optimization, it also comprises a little shape safety valve, this little shape safety valve comprises valve opening and the interior elastic telescopic post of valve opening that is located on the pedestal, elastic telescopic post top is pressed with cover plate, have steam leakage window on the valve opening hole wall of the seat hole hole wall of valve plug below and elastic telescopic post below, described O-ring seal and steam leakage window opposite position are thin layer.So design, when the pressure cooker internal pressure was too high, thin layer broke, and when steam backs down little shape safety valve pressure release, thereby made pressure cooker of the present invention, and is safer.
As optimization, described elastic telescopic post forms by last cup post, following glass post and the helical spring between the two, wherein go up glass post and the mutual clamping of following glass post, formation telescope structure.So design is simple in structure.
Pressure cooker of the present invention has convenient, simple in structure, the safe and reliable advantage of pressure release with safety valve, is widely used in various pressure cookers.
Description of drawings
Below in conjunction with accompanying drawing pressure cooker of the present invention is described further:
Fig. 1 is the product body structure schematic diagram of this pressure cooker with safety valve;
Fig. 2 is the cross-sectional view of A-A among Fig. 1;
It is too high that to be structure shown in Fig. 2 press at pressure cooker Fig. 3, and thin layer breaks, the schematic diagram (arrow is represented the steam that leaks) during little shape safety valve jumping up pressure release;
Fig. 4 is the decomposing schematic representation of each parts among Fig. 1.
Among the figure: 1 be pedestal, 2 for a seat hole, 3 for the valve plug, 4 for valve opening, 5 for the elastic telescopic post, 6 for steam leakage window, 7 for last cup post, 8 for following glass post, 9 for O-ring seal, 10 for annular groove, 11 for stifledly coiling, 12 being thin layer.
The specific embodiment
Embodiment one: shown in Fig. 1 to 4: this pressure cooker comprises seat hole 2, valve plug 3 and little shape safety valve that is opened on the pedestal 1 with safety valve, described little shape safety valve comprises the elastic telescopic post 5 in the valve opening 4 that is located on the pedestal 1 and the valve opening 4, elastic telescopic post 5 tops are pressed with cover plate (not drawing among the figure), have steam leakage window 6 on the hole wall in the seat hole 2 of valve plug 3 belows and valve opening 4 hole walls of elastic telescopic post 5 belows.Described elastic telescopic post 5 is made up of last cup post 7, following glass post 8 and the helical spring between the two, wherein goes up cup post 7 and following glass post 8 mutual clampings, forms the telescope structure.
Described seat hole 2 is provided with O-ring seal 9, sealing cushion rubber 9 tops are stuck on the interior ring platform of described seat hole 2 lower inner wall, and its underpart has annular groove 10, and described valve plug 3 is stuck in O-ring seal interior 9, valve plug 3 bottoms are provided with stifled dish 11, and described O-ring seal 9 is provided with the ring portion of joining with described stifled dish 11.Described O-ring seal 9 is a thin layer 12 with steam leakage window 6 opposite positions.
