Description

Irregular sealing ring

Technical Field

The utility model relates to a sealing washer technical field, in particular to irregular sealing washer.

Background

The sealing ring is a part with sealing performance in a working pressure and certain temperature range, and has good stability and good waterproof, oil-proof and antifouling effects, so that the sealing ring is widely applied to production and life, and the sealing effect of the sealing ring is often influenced by the working pressure, the working temperature, the corrosivity of a sealing medium, the combination of the sealing surface and other factors.

To obtain a good sealing effect, the sealing ring must not only have good sealing performance matching with the sealing environment, but also be tightly attached to the surface of the object to be sealed. At present, for sealing of some irregular curved surfaces, a plurality of sealing rings are mostly adopted and sealed in a mode of applying certain pressure, the positioning is troublesome, the sealing effect is unstable, and the sealing rings and sealed objects are also possibly deformed or damaged under the influence of the sealing pressure.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an irregular sealing washer solves the sealed problem on the irregular surface that mentions in the background art.

In order to achieve the above object, the utility model provides a following technical scheme: the irregular sealing ring comprises a sealing base, wherein a sealing ring is arranged at the upper end of the sealing base, and a groove is formed in the upper end of the sealing ring. The utility model discloses in, irregular sealing washer chooses for use that the adsorptivity is strong, the stronger soft silica gel material of anti deformability makes, the sealing ring with shape, size and the quantity of recess all depend on the shape and the structure on the surface that will seal.

In order to make the sealing ring fit the surface of the product to be sealed more to ensure the sealing effect, preferably, the sealing base is of an annular structure, the inner ring size of the sealing ring is the same as that of the sealing base, and the outer ring size of the sealing ring is smaller than that of the sealing base.

In order to ensure the sealing effect, preferably, the corners of the groove are provided with groove chamfers.

In order to facilitate assembly and ensure a sealing effect, preferably, the sealing base and the corners of the sealing ring are provided with sealing chamfers.

The utility model discloses in, all chamfers are arc chamfer.

Advantageous effects

Compared with the prior art, the beneficial effects of the utility model are as follows:

(1) the groove structure and the sealing surface of the utility model can be completely attached to the irregular surface to be sealed, and the positioning and sealing can be better carried out;

(2) the utility model is convenient to assemble, has good sealing effect, can achieve excellent sealing effect by one sealing element, and is economical and practical;

(3) the utility model discloses do not need great pressure just can realize the location of sealing washer during the installation, can avoid pressure to reach the damage of sealed product to the sealing washer, prolong its life.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an irregular sealing ring, includes sealing base 1, and sealing base 1 upper end is provided with sealing ring 2, and recess 3 has been seted up to sealing ring 2 upper end. The utility model discloses in, irregular sealing washer chooses for use that the adsorptivity is strong, the stronger soft silica gel material of anti deformability makes, and the shape, size and the quantity of sealing ring 2 and recess 3 all depend on the shape and the structure on the surface that will seal. In this embodiment, the surface to be sealed is an arc with 4 smooth protrusions, and an irregular sealing ring with a top end with an arc surface and 4 smooth grooves is adopted.

In order to make the sealing ring more fit the surface of the sealed product to ensure the sealing effect, further, the sealing base 1 is of an annular structure, the size of the inner ring of the sealing ring 2 is the same as that of the inner ring of the sealing base 1, and the size of the outer ring of the sealing ring 2 is smaller than that of the outer ring of the sealing base 1.

In order to ensure the sealing effect, the corners of the groove 3 are provided with groove chamfers 4.

In this embodiment, all the chamfers are arc chamfers.

Example 2

In order to facilitate assembly and ensure sealing effect, further, the corners of the sealing base 1 and the sealing ring 2 are provided with sealing chamfers 5.

In this embodiment, all the chamfers are arc chamfers.

Embodiment 2 is based on embodiment 1, has increased sealed chamfer 5 of sealed base 1 and sealing ring 2 edge, and this structure can make the assembly of irregular sealing washer more smooth and easy.
