Detailed Description
To make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions in the embodiments of the present utility model will be clearly and completely described below, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model. Accordingly, the detailed description of the embodiments of the utility model provided below is not intended to limit the scope of the utility model as claimed, but is merely representative of selected embodiments of the utility model.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in the following figures.
Examples:
as shown in fig. 1 to 3, a sealing ring for a water supply pipe includes: elastomer 1, skeleton 2, interior sealing ring 3, outer sealing ring 4, locating surface 5 and gusset 6.
The elastic body 1 and the framework 2 are of annular structures, and the lower end of the elastic body 1 is fixedly connected with the framework 2. The elastic body 1 is used for fitting a sealing surface, and the elastic body 1 is made of soft materials, can be TPE, TPV, TPU, TPEE, TPS, TPO and TPEA, and is preferably TPV. The elastomer 1 is composed of two layers of sealing rings, an outer sealing ring 4 on the outside and an inner sealing ring 3 on the inside.
The diameter of the inner sealing ring 3 is slightly smaller than that of the pipeline, and the outer surface of the pipeline can be hooped when the inner sealing ring is installed on the pipeline, so that extrusion sealing is formed. Simultaneously, the inner surface of the inner sealing ring 3 is subjected to pressure, so that the inner sealing ring 3 is further tightly attached to the outer surface of the pipeline, and the sealing pressure level is improved.
The outer sealing ring 4 is integrally connected with the inner sealing ring 3, the radius of the outer sealing ring 4 and the radius of the inner sealing ring 3 from top to bottom are increased, and an annular groove is formed between the outer sealing ring 4 and the inner sealing ring 3. After the installation, the outer sealing ring 4 is tightly pressed on the inner surface of the high pressure side of the installation position of the pipeline sealing ring to form extrusion sealing. Simultaneously, the inner ring surface of the outer sealing ring 4 is subjected to pressure, so that the outer sealing ring 4 is further tightly attached to the inner surface of the high-pressure side of the installation position of the pipeline sealing ring, and the sealing pressure level is improved.
The framework 2 is made of hard material polyolefin or polyolefin alloy, preferably PP or ABS alloy, and is connected with the elastomer 1 to increase the deformation resistance of the sealing ring when being pressed. As shown in fig. 3, the radius of the skeleton 2 decreases from top to bottom, i.e., the cross section of the skeleton 2 is triangular with a downward tip. The bottom edge of the framework 2 is uniformly provided with a plurality of triangular openings.
The rib plate 6 is made of the same material as the framework 2, is arranged between the elastic body 1 and the framework 2, a plurality of grooves are formed in the lower end of the elastic body 1 and are uniformly distributed, the upper end of the rib plate 6 is fixedly connected in the grooves, the lower end of the rib plate 6 is fixedly connected with the upper end of the framework 2, and the rib plate 6 and the framework 2 are of an integrated structure. The elastic body 1, the rib plates 6 and the framework 2 are formed by injection molding.
In the utility model, only one groove can be arranged, the groove is in a ring shape, the upper end of the rib plate 6 is embedded into the groove, and the lower end of the rib plate is fixedly connected with the framework 2.
As shown in fig. 2, more preferably, when the grooves are provided in a plurality, the upper ends of the grooves penetrate the elastic body 1, so that the elastic body 1 forms an opening at the bottom end of the annular groove. Compared with the condition that the sealing material does not penetrate, the material consumption required by the molding of the elastomer 1 is reduced, the sealing performance is ensured, the product weight and the product cost are reduced, meanwhile, the longitudinal length is longer than that of the sealing material without penetrating, and the longitudinal length of the hard material is increased, so that the capability of resisting longitudinal deformation when the sealing ring is pressed is improved, and the sealing pressure grade is better.
Compared with a pipeline sealing ring without the rib plates 6, the connecting area of the elastic body 1 and the framework 2 is increased, the connecting strength between the elastic body 1 and the framework 2 can be ensured, the service life of the sealing ring is prolonged, the deformation resistance is enhanced, meanwhile, the rib plates 6 form a partition plate between the outer sealing ring 4 and the inner sealing ring 3, so that the deformation of the outer sealing ring 4 and the inner sealing ring 3 caused by pressure fluctuation is reduced, the material fatigue is slowed down, and the service life of the sealing ring is prolonged. The utility model is applicable to pvc-o pipes, but can also be used to seal other pipes similar in structure to pvc-o pipes.
After the pipeline sealing ring is installed, the outer surface of the pipeline can be hooped by the inner sealing ring 3, the outer sealing ring 4 is pressed and clung to the inner surface of the high-pressure side of the installation position of the pipeline sealing ring, and the positioning surface 5 is abutted to the inner surface of the low-pressure side of the installation position of the pipeline sealing ring, so that the outer sealing ring 4 is pressed and clung to the inner surface of the high-pressure side of the installation position of the pipeline sealing ring, and meanwhile, the sealing effect of the sealing ring to the side sliding of the low pressure after being pressed is prevented, and the sealing pressure level is improved.
