Abstract
The utility model discloses a sealing ring used on a drainage pipeline, which comprises a sealing ring body. A plurality of grooves in corrugate arrangement are arranged on an inner ring face of the sealing ring body, barbs are arranged on an outer ring face of the sealing ring body, the barbs are arranged at one end portion of the sealing ring body, and the barbs and the sealing ring body are integrally formed. By means of the structure, the plurality of grooves in corrugate arrangement are arranged on the inner ring face of the sealing ring body, so the numbers of contact surfaces of the sealing ring body and the pipeline can be increased. Therefore, even though a certain partial position on one contact surface of the sealing ring body and the pipeline is damaged, the integral sealing performance of the pipeline is not influenced. Accordingly, service life of the sealing ring is prolonged, and the sealing performance of the pipeline is effectively improved. In addition, the barbs arranged on the outer ring face of the sealing ring body can prevent mutual slide between a sleeve and the pipeline and avoid backflow of water in installation of the pipeline under the action of gravity fluid.
Description
Technical field
The utility model relates to a kind of sealing ring, is specifically related to a kind of sealing ring that is used on the drainage pipe.
Background technology
At present; The sleeve that drainage pipe for building generally includes the drainage pipe body and two sections drainage pipe bodies are linked together; In order to make the effect that reaches waterproof sealing between drainage pipe body and the sleeve, need between drainage pipe body and sleeve, sealing ring be set usually, and the existing sealing ring that is used on the drainage pipe is mainly the O RunddichtringO; The sealing ring of this structure is applied to relatively poor, the easy damage of sealing effectiveness on the drainage pipe; And the back is installed when fluid washes away drainage pipe for a long time, also cause the drainage pipe body to slide mutually easily, even break away from each other with sleeve.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of not fragile, sealing effectiveness better and can prevent the sealing ring on the drainage pipe that is used for that drainage pipe and sleeve slide mutually after installing.
For realizing above-mentioned purpose; The utility model provides a kind of sealing ring that is used on the drainage pipe; Comprise the sealing ring body, the inner ring surface of said sealing ring body is provided with several and is the groove that corrugated is provided with, and the outer ring surface of said sealing ring body is provided with hangnail.
The beneficial effect of the utility model is: adopt said structure; Several are set on the inner ring surface of said sealing ring body are the groove that corrugated is provided with; Can increase the contact surface number of sealing ring body and pipeline; Even a certain local location is damaged and does not also influence the overall tightness of pipeline on the contacted contact surface of sealing ring body and pipeline like this, prolong the application life of sealing ring body, also improved the sealing performance of pipeline effectively; On the outer ring surface of said sealing ring body, hangnail is set in addition, can prevents the slip each other of sleeve and pipeline, and under the effect of gravity fluid, avoid water to pour in down a chimney during pipe laying.
The utility model can further be set on the end end that described hangnail is arranged on the sealing ring body, and described hangnail and the integrated moulding setting of sealing ring body.
Description of drawings
Fig. 1 is the structure sectional view of the utility model;
Fig. 2 is the concrete application sketch map of the utility model.
The specific embodiment
As shown in Figure 1ly provided a kind of sealing ring that is used on the drainage pipe; Comprise sealing ring body 1; The inner ring surface of said sealing ring body 1 is provided with several and is the groove 11 that corrugated is provided with; The outer ring surface of said sealing ring body 1 is provided with hangnail 12, and described hangnail 12 is arranged on the end end of sealing ring body 1, and described hangnail 12 and the 1 integrated moulding setting of sealing ring body.
As shown in Figure 2ly on the link end face of pipeline 2, step is set; Sleeve 3 is socketed on the step surface 21 of pipeline 2; And the outer ring diameter of sleeve 3 is identical with the outer ring diameter of pipeline 2; After sleeve 3 socket-connected with pipeline 2 like this, the outer ring surface of the outer ring surface of sleeve 3 and pipeline 2 can keep continuity and planarization, is convenient to the assembling of drainage pipe; Be equipped with sealing ring body 1 on the step surface 21 of said pipeline 2 simultaneously, the hangnail 12 on the said sealing ring body 1 can prevent sleeve 3 and pipeline 2 slip each other, makes pipeline 2 more firm with being connected of sleeve 3; In addition for making things convenient for being connected of sleeve 3 and pipeline 2, be provided with chamfering 211 at step surface 21 front ends of said pipeline 2, in the inner ring surface both side ends of sleeve 3 chamfering 31 is set.
