The purpose of this utility model is achieved through the following technical solutions.
A kind of reduction jar tightness system, its spy is that this device is made up of following structure:
The sealing support tube-this is that an end has coupling flange and reduction jar close jar of steel cylindrical body that mouthful flange connects; Two vertical fixedly gussets that axially are arranged with at the circle outer side;
Fixed cross beam-this crossbeam one end for turn a shape structure and the sealing support tube one of them fixedly gusset connect by bearing pin;
Sealing cover-sealing lid is that a periphery is flat cyclic sphere cover body structure; On lid, traverse central vertical and be provided with fixedly gusset, be provided with between two parties on the gusset of sealing cover one have in the gusset in interior channel bar, the channel bar outside of silking be provided with two backstays that have internal chute;
Sealing cover hold-down gear-this device is by a handwheel and be fixed in screw rod handwheel under, that pass fixed cross beam and form, and the termination of its screw rod connects with the interior channel bar thread fit that sealing cover has interior silking;
Sealing cover fixedly pressure handle-this pressure handle is that the termination is hamate pressure handle, its press support fulcrum pin axle be connected in the sealing support cylinder another fixedly on the gusset; When sealing cover was closed, the gib head of pressure handle was pressed on the fixed cross beam.
A kind of reduction of the present utility model jar tightness system adopts handwheel to drive the mode that screw mandrel compresses sealing cover, and comprises sealing cover and crossbeam etc. zero (portion) and all rotate around bearing pin at interior parts, no longer needs manually it to be taken in one's arms and embraces.Significantly reduce the time that opens and closes the reduction jar, only need 1 person-time of * can finish in 0.5 minute behind this equipment of use, significantly reduced " useless working hour ", avoided the sky of jar to burn to greatest extent, improved production efficiency, also prolonged the work-ing life of jar, working strength of workers has also obtained reducing greatly in addition.Through facts have proved, result of use is very good, has greatly and enhances productivity, and improves advantages such as work situation.
