Abstract
The utility model relates to a sealing ring for pressure cookers, which is used on pressure cookers and is composed of a ring body and a sealing lip edge, wherein, the rim of the sealing lip edge is provided with a leakproof ring, and the inner side of the sealing lip edge is provided with a reinforcing rib. The sealing ring for pressure cookers has the advantages of good leak resistance, long service life and easy application.
Description
The utility model relates to the sealing ring that uses on a kind of pressure cooker.
Family's seal ring of pressure cooker used in everyday follows the string owing to rubber wore out after use a period of time at present, produces gas leak phenomenon.Though the user can solve problem by changing a new circle, both bothers like this, can increase the certain economic burden again.The innovation and creation of relevant seal ring of pressure cooker were more in recent years.The manufactured materials that focuses on change pressure cooker circle that these innovation and creation have; The structure of the correction pressure cooker circle that has improves its sealing property.Although these innovation and creation more or less have certain effect, effect is not very remarkable, particularly after the elastomeric material of sealing ring begins to wear out.
The purpose of this utility model provides that a kind of leak resistance is good, the seal ring of pressure cooker of long service life.
The purpose of this utility model is to realize by following technical proposal: this seal ring of pressure cooker is made up of the sealing lip limit on circle body and the circle body, and the edge on sealing lip limit is provided with the leakproof ring, and the inboard on sealing lip limit is provided with reinforcement.The leakproof ring is set, the sealing lip limit is fully opened, guarantee that sealing ring keeps excellent sealing performance at pressure cooker brand, model, factor such as the new and old Shi Junneng that changes.Inboard on the sealing lip limit is provided with reinforcement, mainly is that the sealing property that guarantees sealing ring when the circle body material is also not aging fully can obviously not descend.In addition, it also can suitably save the material of circle body.
This seal ring of pressure cooker so leak resistance is good, has prolonged service life owing to set up leakproof ring and reinforcement greatly.Simultaneously, the utility model implements easily higher utility is arranged.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the schematic cross-section of this seal ring of pressure cooker.
As shown in the figure, this seal ring of pressure cooker comprises circle body (1), sealing lip limit (2), leakproof ring (3) and reinforcement (4).In the present embodiment, the cross sectional shape of leakproof ring (3) is a rectangle.The cross section of leakproof ring (3) also can be shapes such as circle.The inboard reinforcement (4) in sealing lip limit (2) has one group two.According to actual needs, reinforcement (4) also can be provided with more than two groups or two groups.
