Abstract
The invention belongs to the technical field of seals and relates to a combined seal which comprises a circular body. The upper end of the circular body is provided with a circular groove for mounting a rubber seal member. The bottom of the circular groove is evenly and peripherally provided with more than two axial through holes. The lower portion of each through hole is provided with an expanded-hole part penetrating through the lower end of the circular body. The integrated rubber seal members are vulcanized in the circular groove, the through holes and the lower expanded-hole parts of the through holes. The combined seal has the advantages that the integrated rubber seal members are vulcanized in the circular groove, the through holes and the lower expanded-hole parts of the through holes, the rubber seal members in the through holes and the expanded-hole parts mutually hold one another, the rubber seal member in the circular groove is free of leaving the circular groove body even when squeezed and twisted for a long period of time, stability and sealing performance of the seal are increased, the service life of the seal is prolonged, and the combined seal is applicable to spools or can serve as a universal seal body.
Description
Technical field
The invention belongs to the Sealing technical field, refer in particular to a kind of Assembled sealer.
Background technique
Sealing is to prevent fluid or material or the part of solid particle from leaking and prevent the component of the intrusion machinery equipment inside such as introduced contaminants such as dust and moisture between adjacent junction plane.Traditional Sealing comprises ring body, ring body is provided with the installation cavity of installing for rubbery sealed body, install to vulcanize in the cavity rubbery sealed body is arranged, cavity is installed is comprised the annular groove that is located on one of them end face of ring body, offer the fixed hole that communicates with the ring body other end in the annular groove bottom, accordingly, rubbery sealed body comprises the seal ring that is positioned at annular groove and is positioned at the fixed hole rubber cylinder.
The Sealing of said structure is in the process of using, seal ring on the rubbery sealed body contacts with sealed parts, and be squeezed for a long time and reverse, and then can cause the rubber cylinder in the fixed hole to be driven, if things go on like this, rubber seal know from experience to break away from ring body, and Sealing is damaged, and causes that sealing is unreliable and seal durability is short.
Summary of the invention
The purpose of this invention is to provide a kind of Assembled sealer.
The object of the present invention is achieved like this:
A kind of Assembled sealer, comprise ring body, the upper-end surface of ring body is provided with the circular groove of installing for rubbery sealed body, the bottom of described circular groove circumferentially is evenly equipped with through hole axial more than two, the bottom of through hole is provided with the reamer that connects the ring body lower end surface, and sulfidization molding has the rubber seal of integral type in the reamer of described circular groove, through hole and through hole bottom.
The upper-end surface of above-mentioned rubber seal is circular groove or the annular protrusion that is provided with one or more.
Above-mentioned through hole is through hole cylindrical or taper or stepped shape.
The cross-sectional profiles of above-mentioned circular groove is rectangle or trapezoidal or arc.
The cross-sectional profiles of above-mentioned reamer is rectangle or trapezoidal or arc.
The annular groove that with described through hole be communicated with of above-mentioned reamer for arranging in the lower end surface of ring body.
Above-mentioned ring body is that polytetrafluoroethylmaterial material is made.
The present invention compared to existing technology outstanding and useful technique effect is: the present invention's sulfidization molding in the reamer of circular groove, through hole and through hole bottom has the rubber seal of integral type, because the rubber parts in through hole and the reamer has mutual restraining function to the rubber seal in the circular groove, even being squeezed for a long time, the rubber seal in the circular groove reverses, can not break away from the circular groove body yet, strengthen steadiness, sealability and the working life of Sealing, be applicable to do spool or general sealed body.

The upper-end surface of above-mentioned rubber seal 20 is circular groove 21 or the annular protrusion that is provided with one or more.
Above-mentioned through hole 12 is through hole cylindrical or taper or stepped shape.
The cross-sectional profiles of above-mentioned circular groove 11 is rectangle or trapezoidal or arc.
The cross-sectional profiles of above-mentioned reamer 13 is rectangle or trapezoidal or arc.
The above-mentioned annular groove that with described through hole 12 be communicated with of reamer 13 for arranging in the lower end surface of ring body 10 is although the rubber material that uses in annular groove like this is many, fixing more firm.
Above-mentioned ring body 10 is made for polytetrafluoroethylmaterial material.
Above-described embodiment is preferred embodiment of the present invention only, is not to limit according to this protection scope of the present invention, therefore: all equivalences of doing according to structure of the present invention, shape, principle change, and all should be covered by within protection scope of the present invention.
