Abstract
The utility model relates to an air bag type sealing rubber ring for a pressure-cooker characterized in that inflation is implemented through an inflation device. The upper edge opening and an upper edge opening of the sealing rubber ring are connected by a support wall, forming an integral closed air bag. The air bag is connected with an inflation/exhaust device arranged on a cooker cover through one ventilation pipe. The inflation/exhaust device is composed of a metal pipe, a rubber Inflation ball, a core and an exhaust switch. The utility model has the advantages of favorable performance, long service life, and non-air leak due to aging. After sufficient air is inflated in the air bag, the air bag expand outwards. A gap between a cooker cover and a cooker opening is tightly sealed through the upper outer wall and the lower outer wall of the air bag, which is just like the situation that after an inner tire of a tire is fully inflated, no gap exists between the inner tire and an outer tire.
Description
The utility model belongs to a kind of rubber ring of pressure cooker sealing.
Pressure cooker has become a kind of important cooker in the kitchen with the characteristics of its fast energy-and time-economizing of cooked food.The O-ring seal of pressure cooker is very easy to badly cause gas leakage, makes pressure cooker lose its characteristic and has become ordinary pan.Need the frequent O-ring seal of changing like this.Existing several gasket cement of pressure cooker circle is not long service life, an available wheat harvesting period that has, and what have can only be with tens days.Therefore the consumer complains that the working pressure pot will change tens O-ring seals in 1 year, and the money of cost is also more than buying a pressure cooker.
When easily bad and reason gas leakage of the O-ring seal of pressure cooker is to use pressure cooker, HTHP in pot weakens the very easily aging distortion elasticity in the key position-lip limit of O-ring seal, and causing between O-ring seal and pot cover, the pot mouth has the slit to produce gas leakage even drainage.The patent of invention 911066810 that the present technique field retrieves discloses a kind of " inflatable rubber seal and hermetically-sealed construction thereof ", and it is to utilize the inner gas that produces behind the heated pressure container to enter the hollow ring of O-ring seal.This inflation mode can not be inflated according to actual needs, does not reach required aeration quantity, and result of use is undesirable.
The purpose of this utility model is in order to address the above problem, a kind of good seal performance to be provided, and service life is lasting, carries out inflatable air bag formula gasket cement of pressure cooker circle by aerating device.
The technical solution of the utility model is: the two lip limit mouths up and down of O-ring seal are linked the air bag that forms a complete closure with abutment wall, with a breather pipe filling on air bag and the installation pot cover, Exhaust airbag device are connected.Fill, exhaust apparatus is made up of metal tube, rubber inflatable ball, valve inside, air discharge cook.
The utility model can not cause gas leakage because of cushion rubber lip limit aging distortion elasticity weakens by after date when using one section.Because after charging into the gas of q.s in the air bag, the outside expanding volume of air bag enlarges, and the outer wall up and down of air bag just lip limit is tight with sealing between pot cover and the pot mouthful, and the inner tube of a tyre that resembles tire is full of behind the gas and has not a particle of the gap between the cover tire.
Accompanying drawing is the utility model cross-sectional view, and concrete structure is as follows: air bag (1), breather pipe (2), metal tube (3), air discharge cook (4), valve inside (5), inflatable ball (6).
The utility model is finished the work like this.Close and check earlier whether air discharge cook (4) is shut behind the lid of pressure cooker, pinching inflatable ball (6) with hand again makes the gas process metal tube (3) in the ball, the valve inside (5) and the breather pipe (2) of air inlet enter air bag (1), pinch continuously several times, pinch after inflatable ball (6) requires great effort very much when feeling in one's hands, air bag (1) is just by sufficient gas, and the outer wall up and down of air bag (1) is close to pot cover and pot mouth.At this moment, pressure cooker has sealed tight.In the time of after food boils, will outwarding winding pot cover, air discharge cook (4) is opened, the gas in the air bag (1) is discharged its volume-diminished.The pot cover of outwarding winding like this is easily easy.
Structure of the present utility model and operation principle are equally applicable to industrial pressure vessel.
Claims (2)
1, a kind of gasbag-type gasket cement of pressure cooker circle, the two lip limit mouths up and down that it is characterized by cushion rubber link the air bag that forms a complete closure with abutment wall, breather pipe with air bag with fill, exhaust apparatus is connected.
2, as claimed in claim 1ly fill, exhaust apparatus, it is characterized by on the pot cover that is installed in pressure cooker, form by metal tube, rubber inflatable ball, valve inside, air discharge cook.
