Abstract
The utility model relates to a sealing ring of a pressure cooker, which is composed of a circular ring body, wherein the inner edge of the circular ring body forms an upper and a lower layers which are respectively and outward turned in the upper direction and the lower direction; the cross section of the circular ring body is a horizontal U-shaped structure with an opening toward a circle center of the circular ring body; either the upper layer or the lower layer of the circular ring body is provided with a plurality of through holes. When the pressure in a cooker exceeds the set safety pressure, the through holes on the circular ring body of the utility model can realize safe pressure relief, and a high-pressure gas in the cooker is relieved from the through holes on the sealing ring so as to ensure that the pressure cooker or an electric pressure cooker is safe in use. The utility model has the characteristics of reasonable structure and safe use.
Description
Technical field
The utility model is the sealing ring of the accessory of a kind of pressure cooker or electric pressure cooking saucepan, particularly a kind of pressure cooker, belongs to the improvement technology of existing seal ring of pressure cooker.
Background technology
Existing pressure cooker or electric pressure cooking saucepan major part rely on safety valve to realize safety relief, but obstruction or the inefficacy easily of traditional safety valve causes quick-fried pot; China ZL98224816.4 patent, provided a kind of by being fixed on soft sealing ring on the pot cover inner chamber perisporium and the interior pot upper edge dynamic seal (packing) pressure relief device that the pressure release gap slot offered on the circle limit forms that turns up, it is big to offer pressure release gap slot technology difficulty but turn up in interior pot upper edge on the circle limit, influences attractive in appearance again.China's ZL91111160.3 patent, provided a kind of utilize elastic cover to be subjected to the high pressure distortion after, the scheme of pressure release is come in the gap between pot cover and the sealing ring, but because sealing ring itself is flexible, pressure release gap, pressure release pressure transient are difficult to realization.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned sealing ring, provide a kind of and can guarantee sealing, can when the pressure cooker internal pressure surpasses the safe pressure of setting, guarantee the sealing ring of the pressure cooker that the gases at high pressure in the pot release from the gap between pot cover and the sealing ring again.
The technical scheme that realizes the utility model purpose is: the utility model is made of circle body, the interior edge of circle body for respectively up and down direction turn up upper and lower two-layer, the cross section of circle body be the opening of accumbency to the U in circle body center of circle font structure, on the upper and lower two-layer any one deck of circle body, be provided with several through holes.
In technique scheme, be respectively equipped with several through holes on two-layer in that circle body is upper and lower.
The shape of above-mentioned through hole can be circular, or oval, or polygon, or polygonal star, or flower is distinguished shapes such as shape.
Its diameter dimension scope of the size of above-mentioned through hole is 0.1～20 millimeter.
The beneficial effects of the utility model are: sealing ring is installed between the pot cover and pot body of pressure cooker or electric pressure cooking saucepan, increase along with pot inner pressure, gap between pot cover and the pot body also can become big thereupon, when pot inner pressure surpasses the safe pressure of setting, the interstice coverage that gap between pot cover and the pot body can seal just above sealing ring, through hole on the sealing ring can be realized safety relief, release in the through hole of gases at high pressure in the pot from the sealing ring, thereby guarantee the safety that pressure cooker or electric pressure cooking saucepan use, have characteristics rational in infrastructure, safe in utilization.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a use principle pressure release state partial enlarged drawing of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the specific embodiment.
As shown in Figure 1, the utility model is made of circle body 1, circle body 1 can adopt full rubber or silicon rubber to make, the interior edge of circle body 1 for respectively up and down direction turn up upper and lower two-layer, the cross section of circle body 1 is the U font structure of the opening of accumbency to circle body 1 center of circle, at circle body 1 upper and lower two-layer any one deck, or two-layer several through holes 11 that is provided with, the quantity of through hole 11 is established 6 for every layer, through hole 11 be shaped as circle, its aperture is 3 millimeters.When the utility model uses, as shown in Figure 2, the utility model is installed between the pot cover 3 and pot body 2 of pressure cooker or electric pressure cooking saucepan, increase along with pot inner pressure, gap between pot cover 3 and the pot body 2 also can become big thereupon, when pot inner pressure surpasses the safe pressure of setting, the interstice coverage that gap between pot cover 3 and the pot body 2 can seal just above sealing ring, through hole 11 on the sealing ring can be realized safety relief, gases at high pressure in the pot release in through hole 11, thereby guarantee the safety that pressure cooker or electric pressure cooking saucepan use, have characteristics rational in infrastructure, safe in utilization.
When the utility model was specifically implemented, the position of through hole 11, shape, pore size, quantity can be determined according to the concrete structure design or the test of pressure cooker or electric pressure cooking saucepan.
