Abstract
The utility model relates to an iron lid-screwing-typed pressure cooker. The material of an existing buckling-typed aluminium pressure cooker is changed into cast iron, and the bearing connection method is changed into the threaded connection method. Sealing rings are installed in the threaded knife-withdrawing slot of the lid of the cooker and the chamfering inclined plane of the mouth of a cooker cylinder, and through the adjustable pressing force of the threaded connection, the ageing shrinkage of the rubber sealing rings is compensated to realize reliable sealing. The appearance is painted with high-temperature-resistance paint to prevent rusting. The mouth of the lid of the cooker is provided with a plurality of longitudinal slots. When a constant-pressure exhaust valve and a safety valve are out of order for being blocked, the lid of the cooker is forcibly opened by being tripped to prevent explosion. The utility model has firm structure, a high sealing degree, safety of asepsis and harmlessness, low cost, less investment and obvious effect.
Description
The utility model relates to the iron cap-rotating type pressure cooker of a kind of kitchen cooker.
At present the attaching type aluminum pressure cooker that uses of kitchen is not only high regional indispensable cooker above sea level, and also is commonly people in low area above sea level and accepts.This be because it save time, energy-conservation, the soft aquatic foods of cooking food, it is harmful to health that its weak point is an aluminium element, in addition, the rubber seal of attaching type is under higher temperature, pressure, easily aging the contraction, and the space that holds sealing ring between pot bucket and the pot cover is fixed.Like this, when the new clothes sealing ring, withholding of pot bucket and pot cover cooperates tightly, even is difficult to tip in, and after using a period of time, rubber ring is aging to be shunk, withhold to cooperate to fluff, and seal failure, pressed gas sprays from seal clearance, does not reach setting pressure.When serious, sealing ring is gone out one section by pressed gas and is caused the accident.
The purpose of this utility model provides a kind of irony that health-care effect, high sealing iron cap-rotating type pressure cooker are arranged for overcoming outside the above-mentioned deficiency.
Iron cap-rotating type pressure is made up of pot bucket (1), pot cover (2), sealing ring (3), constant pressure exhaust valve (4), safety valve (5) and square contiguous block (6), handle (7) etc.Pot bucket and pot cover are with being threaded, and the appearance dress is coated with high temperature resistant paint.
Be further described below in conjunction with accompanying drawing:
Accompanying drawing one is the structure chart of iron cap-rotating type pressure cooker.
Accompanying drawing two is pot bucket, pot cover connecting portion profile.
Accompanying drawing three is pot cover oral area fluting schematic diagrames.
With reference to accompanying drawing one, two, the pot bucket (1) of iron cap-rotating type pressure cooker is made of iron, and oral area has external screw thread.The oral area of pot cover (2) has internal thread, and has several cannelures (seeing accompanying drawing three), makes oral area have the elasticity of hypertonic.Pot cover internal thread escape place is provided with special-shaped rubber ring (3), and the constant pressure exhaust valve (4) the same with existing attaching type aluminum pressure cooker is equipped with at the pot cover top, presses 981 millibars in keeping.The setting pressure of safety valve (5) is 1962 millibars, the nearly screw thread place of pot cover and pot bucket is riveting contiguous block (6), in order to bakelite handle (7) to be installed, iron cap-rotating type pressure cooker inner surface is through thermo-chemical treatment, outer surface is coated with heat resistance paint (500 ℃) in case get rusty, and satisfy the selection requirement of the people to the outward appearance look with different tones, under the normal operating position, pot bucket (1) and pot cover (2) bear internal pressure to be threaded, and the degree that compresses of borrowing the adjustability adjusting sealing ring that is threaded, the aging contraction of compensation rubber sealing circle (3), it is tight that sealing is remained.When constant pressure exhaust valve (4) stops up, the interior pressure when being increased to 1962 millibars, safety valve (5) works, fuse piece dashes wears exhaust, when constant pressure exhaust valve (4) and safety valve (5) all stop up when malfunctioning, when internal pressure is increased to 2943 millibars, oral area has the pot cover (2) of elasticity hypertonic under the internal pressure effect, force to break away from the screw thread of pot bucket (1), and be opened, avoid pressure cooker to burst.
The utility model is compared with existing attaching type aluminium pressure cooker, keeps its outstanding advantages, the soft aquatic foods of cooking food, and time-saving energy-saving has remedied its deficiency, and is not only harmless on the contrary useful in people's health. In addition, greatly prolong the service life of sealing ring, reduced the accident link. Appearance colour is beautiful, low cost of manufacture. Although cast iron matter is crisp, percentage elongation is little, and is blocked when malfunctioning when constant pressure exhaust valve (4) and safety valve (5), has the internal pressure that the telescopic pot cover of elasticity (2) can be increased and washes open and avoid bursting. Remedying its deficiency, is a kind of comparatively desirable cooker for kitchen use.
Claims (2)
1, a kind of iron cap-rotating type pressure cooker of being made up of pot bucket, pot cover, sealing ring, constant pressure exhaust valve, safety valve, bakelite handle and contiguous block thereof is characterized in that: made of iron, pot bucket (1) and pot cover (2) are with being threaded; A special-shaped rubber seal is installed in the pot cover internal thread escape.
2, pressure cooker according to claim 1 is characterized in that: have equidistant several cannelures around the pot cover oral area, every groove is cut from the edge and is passed to internal thread escape section start.
