Abstract
The utility model relates to a single-sided arc positioning rubber sealing ring which comprises a cylindrical rubber barrel wall and a coaxial inner hole, wherein the cylindrical rubber barrel wall is formed by integral injection molding. The utility model is characterized in that the mounting surface of the cylindrical rubber barrel wall is made into a radial plane, the sealing surface of the cylindrical rubber barrel wall is made into a semicircular cambered surface, and the circumferential surface of the inner hole of the sealing ring is coaxially provided with an axial table. The utility model has the advantages of scientific design and simple structure, and is easy to manufacture; and compared with the like sealing ring, the rubber sealing ring provided by the utility model made of the same rubber has the advantages of obviously longer service life and better sealing effect, and can compensate the deformation.
Description
Technical field
The utility model belongs to the rubber product field, relates to rubber seal, especially a kind of pedion circular arc location rubber seal.
Background technique
Seal ring is mainly used in dielectric leakages such as preventing grease, profit in the seal arrangement, prevents that simultaneously extraneous medium from getting in the seal arrangement, is requisite accessory in various water-tight equipments, valve, the pipeline.Existing seal ring is the simple circle loop configuration of different size, in use, receives multiple factor affecting such as temperature, pressure, burn into wearing and tearing for a long time; Deform easily, cause the sealing effect variation, even leak; Especially in the high seal arrangement of some required precisions, cause greater loss easily, and change the seal ring complicated operation; The labor intensive material resources increases cost.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, the pedion circular arc location rubber seal that a kind of design science, simple in structure, reliability and durability are provided, is easy to assemble.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of pedion circular arc location rubber seal comprises the cylindrical shape rubber barrel of integrated injection molding and coaxial endoporus, and it is characterized in that: the radial plane is processed in said cylindrical shape rubber barrel lower end surface, and said cylindrical shape rubber barrel upper-end surface is made as the semicircle cambered surface.
And, the coaxial pillow block that is shaped on of the endoporus circumferential surface of said seal ring.
The advantage and the good effect of the utility model are:
1, this seal ring plane one end is used for the location; Cambered surface is used for sealing, makes things convenient for installing and locating, is easy to assembling; Cambered surface is used for sealing elastic strain takes place more easily; Have better sealability, and when standing multiple extraneous factor for a long time and influence, can more effectively compensate distortion, prolong the working life of seal ring.
2, be shaped on coaxial pillow block on this seal ring inner peripheral surface, can locate axial position exactly during assembling, be convenient to locate the coaxial Sealing that is installed in the seal ring.
3, the utility model design science, simple in structure, easy to manufacture is compared the identical material rubber of employing and is processed, and significantly promotes working life and sealing effect with similar seal ring; And can compensate distortion; Have longer working life, reduce cost, use manpower and material resources sparingly.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment
Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of pedion circular arc is located rubber seal, comprises the cylindrical shape rubber barrel 1 and coaxial endoporus 2 of integrated injection molding, and the utility model innovative point is:
The attachment face of said cylindrical shape rubber barrel is processed radial plane 5, location when being convenient to install; In addition, in order to obtain better sealability, the sealing surface of said cylindrical shape rubber barrel is processed semicircle cambered surface 4.
For the axial position of accurate location and installation at the ring inner hole parts; As shown in Figure 2; The coaxial pillow block 3 that is shaped on the circumferential surface of sealing circle endoporus; Can realize the axially locating of Sealing in seal ring through this pillow block,, improve sealing effect to avoid the circumferential wrinkling of seal ring or to reverse the part of being caused and reveal.
Claims (2)
