The inwall on described seal ring " U " shape structure both sides all has the step that convexes to form.
There is the groove of the step coupling that convexes to form with seal ring " U " shape structure both sides inwall on described supporting base two surfaces.
The area of described groove cross section is not more than the area of the step cross section that convexes to form.
Described supporting base and top board or press table are fixed by " U " shape both sides of bolt press seal circle.
Above-mentioned elastic packing positioning device can be applicable to the mechanism hand hand touch end, is used for catalyst carrier is fixed in catalyst cupport is processed.Seal ring in the elastic packing positioning device adopts elastic material to make, and usually can adopt such as materials processings such as rubber, elastomeric plastics and make, and seal ring is an annulus, and cross section is outwardly open " U " shape structure; The supporting base that mates with seal ring also is a circle structure, when supporting base and seal ring combination seal ring " U " shape structure both sides conveniently are enclosed within on upper and lower two surfaces of supporting base, and the bottom of " U " shape structure reserved enough spaces, top board and the press table of two rings compressed respectively the both sides of " U " shape seal ring, can be fixed by bolt, the space that " U " shape structural base is reserved forms the hollow ring of sealing, be provided with the vent that is communicated with hollow ring and outside at supporting base, vent can be communicated with external high pressure gas usually.
When carrying out the catalyst carrier coating processing, carrier is placed in the annular seal circle of upper and lower two groups of elastic packing positioning devices, after the vent inflation, seal ring expands and the carrier outer wall to be fixed and to be compressed to carrier forms carrier to external sealed, after coating processing is finished in the discharge seal ring gas can take out carrier.
Fix in order to guarantee the hollow ring volume that elastic packing positioning device headspace forms, the present invention is provided with the step that convexes to form with the inwall on seal ring " U " shape structure both sides, match and on supporting base two surfaces groove is set, the step that convexes to form forms annulus at seal ring " U " shape inner structural wall, groove also forms the annulus of corresponding coupling on the supporting base surface, the area of groove cross section is not more than the area of step cross section usually.When the combination of supporting base and seal ring, step embeds in the groove, and the location is convenient, accurately, the elastic space size uniformity that hollow ring forms, and it is better that the step that forms at upper and lower pressing plate extruding lower convexity fills up the groove sealability.
Helpfulness of the present invention: the present invention adopts " U " shape ring structure, fixing by the sealing of rigid support seat, the hollow ring that forms is not yielding, carrier is fixing reliable, sealability is better, arranged projection and coupling the further accurate stable of groove structure the hollow ring volume, install and the catalyst-coated processing more convenient, sealability is better.
