Abstract
The utility model discloses a kind of sealing ring, the sealing ring includes sealing ring body sealing ring body, an outwardly extending A leakage-proof ring of circle is equipped at the upper marginal position of the sealing ring body, the inner peripheral surface of sealing ring body is circumferentially with the elastomeric element that section is cambered surface, through-hole circumferentially is equipped in the elastomeric element, elastomeric element, sealing ring body and A leakage-proof ring construction are integrated.The sealing ring can prevent it from shifting during the installation process, and the sealing ring has good sealing performance.
Description
Technical field
The utility model relates to seal member fields, and in particular to a kind of sealing ring.
Background technique
For better seal effect, sealing ring can be provided between the usual pump housing and pump cover, but sealing ring producer is
Control cost, conventional ring structure is all relatively simple on the market at present, therefore is easy to happen offset during the installation process,
Lead to the leakproofness decline of pump.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model relates to a kind of sealing ring, the sealing ring can
Prevent it from shifting during the installation process, and the sealing ring has good sealing performance.
According to technical solution provided by the utility model, a kind of sealing ring, the sealing ring includes sealing ring body sealing
Ontology is enclosed, an outwardly extending A leakage-proof ring of circle, the inner circumferential of sealing ring body are equipped at the upper marginal position of the sealing ring body
Face is circumferentially with the elastomeric element that section is cambered surface, is equipped with through-hole circumferentially in the elastomeric element, elastomeric element, close
Seal ontology and A leakage-proof ring construction are integrated.
Further, the elastomeric element has multiple, and multiple elastomeric elements are linked together.
Further, an outwardly extending B leakage-proof ring of circle is equipped at the lower edge position of the sealing ring body.
Further, the cross-sectional area of the B leakage-proof ring is gradually reduced by B leakage-proof ring inward flange to its outer edge, and B
Leakage-proof ring is bent gradually downward by inner edges to its outer edge and is inwardly collapsed.
Further, the sealing ring body is L shape, including the A seal section and B seal section being linked together.
Further, the cross-sectional area by A leakage-proof ring is gradually reduced by A leakage-proof ring inward flange to its outer edge, and
And A leakage-proof ring is bent gradually downward by inner edges to its outer edge and is inwardly collapsed.
From the above as can be seen that technical solution provided by the utility model have compared with prior art it is following excellent
Point: first, it is located at the hollow elastomeric element on sealing ring body inner peripheral surface, it is described when elastomeric element is by radial compression
Through-hole can provide sufficient space for the deformation of elastomeric element can prevent sealing ring sliding offset, lift-off seal effect.Its
Two, it positioned at the design of the leakage-proof ring at sealing ring body edge, can prevent liquid from leaking from the edge of sealing ring, improve sealing ring
Sealing performance.
Detailed description of the invention
Fig. 1 is the utility model sectional side elevation.
1. sealing ring body, 110.A seal section, 120.B seal section, 2. elastomeric elements, 3. through-holes, 4.A leakage-proof ring, 5.B
Leakage-proof ring.
Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below in conjunction with specific embodiment, and
Referring to attached drawing, the utility model is further described.Wherein identical components are presented with like reference characters.It needs
Illustrate, word "front", "rear" used in the following description, "left", "right", "up" and "down" refer to the side in attached drawing
To.The word "inner" used and "outside" refer respectively to the direction towards or away from geometric center of specific component.
As shown in Figure 1, the utility model provides a kind of sealing ring, the sealing ring includes:
Sealing ring body 1, the sealing ring body 1 are L shape, are sealed including the A seal section 110 being linked together up and down and B
Section 120, forms a step between the A seal section 110 and B seal section 120, the step can play the role of limit, prevents
Only sealing ring sliding offset.
Elastomeric element 2, the elastomeric element 2 have multiple, and multiple elastomeric elements 2 are sequentially arranged in sealing ring body from top to bottom
It on 1 inner peripheral surface, and is linked together with the sealing ring body 1, the section of each elastomeric element 2 is cambered surface, elasticity
Component 2 is equipped with its through-hole 3 circumferentially, and when elastomeric element 2 is by radial compression, the through-hole 3 can be elastic portion
The deformation of part 2, which provides sufficient space, can prevent sealing ring sliding offset, lift-off seal effect.
A leakage-proof ring 4, the A leakage-proof ring 4 are set to the top edge of A seal section 110, and the cross-sectional area of A leakage-proof ring 4 is by A leakproof
4 inward flanges to its outer edge is enclosed to be gradually reduced, and A leakage-proof ring 4 be bent gradually downward from inner edges to its outer edge and to
Interior gathering.The A leakage-proof ring 4 can be close to pump housing inner wall, prevent liquid from leaking from the top edge of sealing ring, improve sealing ring
Sealing performance.
B leakage-proof ring 5, the B leakage-proof ring 5 are set to the lower edge of B seal section 120, and the cross-sectional area of B leakage-proof ring 5 is by B leakproof
5 inward flanges to its outer edge is enclosed to be gradually reduced, and B leakage-proof ring 5 be bent gradually downward from inner edges to its outer edge and to
Interior gathering.The B leakage-proof ring 5 can be close to pump housing inner wall, prevent liquid from leaking from the lower edge of sealing ring, improve sealing ring
Sealing performance.
It should be understood by those ordinary skilled in the art that: the foregoing is merely specific embodiment of the utility model and
, it is not intended to limit the utility model, all any modifications within the purport of the utility model, made, change equivalent replacement
Into etc., it should be included within the scope of protection of this utility model.
