Abstract
The utility model relates to an internal elastic sealing ring. The cross section of the internal elastic sealing ring comprises two curve lip sections; the lip of the two curve lip sections is faced to the inner of sealing ring; a plurality of small column heave sets, which are distributed on the same circle and faces to the inner edge of the other curve lip section, are provided on the inner edge of the curve lip section. The utility model of the new type internal elastic sealing ring, which compares with the sealing ring of the existing pressure cookers, has the advantages of fine elasticity and indefectible.
Description
Technical field
The utility model relate generally to cooker specifically, relates to a kind of novel internal elastic type seal ring.
Background technique
Existing high-pressure cooker sealing ring is made with plastics or rubber, and its cross section is essentially the V-arrangement that keeps flat, and opening is towards the inside of seal ring.During use, it is embedded in the groove of inside, high-pressure pot cover edge, be tightened on high-pressure pot cover on the pressure cooker body after, high-pressure cooker sealing ring in high-pressure pot cover lower end surface and a upper-end surface of pressure cooker body top edge between seal.This high-pressure cooker sealing ring uses in the near future, one side is shape because the both sides of enough forming V-shape cross sections become to change, be close together mutually, the just very fast disappearance of elasticity, on the other hand because the connection part on the both sides of enough forming V-shape cross sections is weak, very easily damage, two aspects all cause it can not play seal action well.
Summary of the invention
The technical problem that the utility model will solve existing high-pressure cooker sealing ring elasticity evanescence and damage easily provides a kind of novel internal elastic type seal ring.
Novel internal elastic type seal ring of the present utility model, it is characterized in that, its cross section comprises cross section, two arc lip limits part, the lip of cross section, two arc lip limits part is towards seal ring inside, and the roundlet columnar projections towards the inward flange of another arc lip limit part of multicomponent cloth on same circumference arranged on the inward flange of cross section, arc lip limit part.
Novel internal elastic type seal ring of the present utility model also comprises a rectangular cross-section part, and the non-lip end of the last lower limb at grade of rectangular cross-section part and cross section, two arc lip limits part is connected as a single entity.
Novel internal elastic type seal ring of the present utility model, also be included in many muscle of the non-lip end setting of arc lip limit cross section part and cross section, arc lower lip limit part, they are spaced from each other, be evenly distributed on the same circumference arc lip limit cross section part and cross section, arc lower lip limit part in the connection.
Novel internal elastic type seal ring of the present utility model, the lip limit of cross section, last arc lip limit part is relative with the lip limit of cross section, arc lower lip limit part, and the thickness at the lip limit of cross section, last arc lip limit part and the lip limit of cross section, arc lower lip limit part place is respectively greater than the thickness of last arc lip limit cross section part and cross section, arc lower lip limit part other parts.
Novel internal elastic type seal ring of the present utility model is compared with existing high-pressure cooker sealing ring, because it comprises two arc lip limit parts, so good springiness; Owing to the roundlet columnar projections of many groups towards another arc lip limit part arranged on the internal surface of one arc lip limit part,, can keep the elasticity of two arc lip limit parts muchly so two arc lip limit parts can not be close together; Because the non-lip end and the rectangular cross-section part of its two arcs lip limit part are connected as a single entity, the connection part of two arc lip limit parts is strengthened, and seal ring is not fragile.
Description of drawings
Fig. 1 is the perspective diagram of novel internal elastic type seal ring of the present utility model;
Fig. 2 is the cross-sectional schematic representation of the amplification of novel internal elastic type seal ring shown in Figure 1
Embodiment
For further specifying novel internal elastic type seal ring content of the present utility model, characteristics and effect, describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Referring to Fig. 1 and Fig. 2, novel internal elastic type seal ring of the present utility model comprises cross section, arc lip limit part 2 and cross section, arc lower lip limit part 3 on the rectangular cross-section part 1.The non-lip end and the rectangular cross-section part 1 of cross section, last arc lip limit part 2 and cross section, arc lower lip limit part 3 are connected as a single entity.
The horizontal axis of cross section, last arc lip limit part 2 and cross section, arc lower lip limit part 3 relative moment tee section parts 1 can be symmetrical, also can be asymmetric.
The inward flange 21 of cross section, last arc lip limit part 2 and the inward flange 31 of cross section, arc lower lip limit part 3 can be two sections camber lines, also can be two sections circular arc lines, and two sections circular arc lines are on same circumference.
The outward edge 23 of cross section, last arc lip limit part 2 and the outward edge 33 of cross section, arc lower lip limit part 3 are two sections camber lines.
The lip limit 22 of cross section, last arc lip limit part 2 is relative with the lip limit 32 of cross section, arc lower lip limit part 3, and the thickness at lip limit 22 and 32 places, lip limit is respectively greater than the thickness of cross section, last arc lip limit part 2 and cross section, arc lower lip limit part 3 other parts.
Has roundlet columnar projections 4 on the inward flange of cross section, last arc lip limit part 2 towards the inward flange of cross section, arc lower lip limit part 3.Roundlet columnar projections 4 is spaced apart from each other, and three roundlet columnar projections 4 are one group, and even branch is six groups on same circumference.Also roundlet columnar projections 4 can be arranged on the inward flange of cross section, arc lower lip limit part 3.
Referring to Fig. 2, non-lip end in cross section, last arc lip limit part 2 and cross section, arc lower lip limit part 3 is provided with many muscle 5, and they are spaced from each other, and are evenly distributed on the same circumference, so that cross section, arc lip limit part 2 and cross section, arc lower lip limit part 3 in the connection, the intensity of increase seal ring.
