Abstract

Provided is a connector lap joint type seal ring. A main body of the seal ring is of an O-shaped annular disc structure. A section opening is formed in the disc structure of the seal ring, cuts at the two ends of the section opening correspond to each other and are attached, two lap joint type step faces are arranged on the cuts at the two ends respectively, the heights of the step faces are gradually decreased from the ends of the cuts to the inner end of the ring, and meanwhile a layer of graphite material coating is further arranged on each step face. The connector lap joint type seal ring is simple in process, convenient to process, easy to assemble and excellent in safety performance.

Description

A kind of interface overlap joint type seal ring
Technical field
The utility model relates to the mechanical sealing element field, is specially a kind of interface overlap joint type seal ring.
Background technique
In general; in numerous seal means of field of sealing technology; adopt seal ring axle spare to be sealed very general; existing seal ring mostly is cast iron greatly or stainless steel material is made; weight is heavier and cost of production is higher; processed complex; simultaneously; often only has single seal action; for the frequent axle spare that needs slip; need to apply lubricant method, in general lubricant method, usually can adopt the mode of cut-offfing the face opening at the seal ring anchor ring to realize; opening on this seal ring only has 0.1mm ~ 0.15mm usually; its too small openings is easily because of the locking overheating failure, the excessive leakage of oil of then can leaking gas of opening, simultaneously; the inertia of oil ring self was larger when penetrating end-face structure also can cause work about this; energy consumption is larger, causes seal wears speed to be accelerated.Along with the improvement of equipment, the enhancing of environmental consciousness, existing requirement improves, and this seal ring more and more can not satisfy engineering demand.
The model utility content
The technical problem that the utility model solves is to provide a kind of interface overlap joint type seal ring, and its reasonable in design, tightness are superior, can solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of interface overlap joint type seal ring, the ring-shaped disc chip architecture that its seal ring main body is the O type, and have a section opening at this disc structure, the otch at the two ends of described section opening is corresponding and applying mutually, the step surface of two overlap joint types is set respectively on its two ends otch, the height of this step surface reduces to ring the inner gradually from cut ends, simultaneously, also is provided with one deck graphite material coating on this step surface.
In the utility model, the thickness of described graphite material coating is 200 μ m ~ 500 μ m.
Beneficial effect: the utility model is simple in structure, easy to use, the otch at two ends is respectively equipped with the step surface of two overlap joint types, two step surfaces can be bonded to each other, wear-resistant, guaranteed that the seal ring two ends can fit tightly for a long time, gas leak phenomenon can not occur, prolong the working life of seal ring, reduced user cost.
Description of drawings
Fig. 1 is the section hatch frame schematic representation of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of interface overlap joint type seal ring referring to Fig. 1, in the present embodiment, seal ring 1 main body is a flat disc disc structure, has a section opening at this disc structure, and section opening both sides have overlap joint button step 2, the height of the step surface of this step 2 reduces to ring the inner gradually from cut ends, simultaneously, also be provided with one deck graphite material coating 3 on the step surface of this step 2, the step 2 of both sides can be bonded to each other, and fit after installation closely, sealability is excellent.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims (2)

1. interface overlap joint type seal ring, the ring-shaped disc chip architecture that its seal ring main body is the O type, it is characterized in that, disc structure at seal ring has a section opening, the otch at the two ends of described section opening is corresponding and applying mutually, and the step surface of two overlap joint types is set respectively on its two ends otch, and the height of this step surface reduces to ring the inner gradually from cut ends, simultaneously, on this step surface, also be provided with one deck graphite material coating.
2. a kind of interface overlap joint type seal ring according to claim 1 is characterized in that, the thickness of described graphite material coating is 200 μ m ~ 500 μ m.
