Description
Technical field
The utility model relates to the online prosthetic device of a kind of flange sealing surface, belongs to portable maintenance equipment technical field.
Background technology
In chemical enterprise, most equipment relies on Flange joint, because Chemical Manufacture inclement condition is close
Front cover usually can because of pressure medium, temperature, corrosion; Cause washing away of flange sealing surface, rotten
The change of erosion sealing surface material, causes sealing surface to lose efficacy.What chemical industry was particular about is ageing, as
Fruit sealing surface occurs just taking replacing means, and these means are all right for little sealing surface, if the sealing surface on large sealing surface or equipment then can spend the longer time, can not meet ageing requirement very well.
Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of online prosthetic device of flange sealing surface repairing flange sealing surface sealing deficiency online, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: the online prosthetic device of flange sealing surface, and it comprises means of abrasion and fixed adjustment part, and means of abrasion is made up of interconnective terminal pad and grinding head, and the abradant surface of grinding head is contacted by flour milling with flange; Fixed adjustment part is made up of cross arm, axial adjustment screw rod and terminal pad governor motion, axial adjustment screw rod is screwed in the end of cross arm, terminal pad governor motion is made up of backstay, spring, clamp nut, the direct-connected cross that is connected on of backstay that hangs down props up tube hub, and spring, terminal pad and clamp nut are socketed on vertical backstay from the bottom to top successively.
The online prosthetic device of above-mentioned flange sealing surface is provided with bearing between terminal pad and clamp nut.
Means of abrasion is divided into inner sealing surface grinding, the grinding of external seal face and end surface grinding according to flange institute abradant surface.
Compared with the prior art, the utility model goes out aly can be mounted to instrument equipment carrying out grind for the flange design that surface roughness does not reach seal request, the fixing of this device is made up of with the axial adjustment screw rod be connected thereon cross arm, can well adapt to various caliber by rotating four axial adjustment screw rods; Backstay is connected at the center of cross arm, linking springs, terminal pad and compression spiral shell successively on the securing lever, to realize the fixing of milling tool, just can rotate grinding tool grind by installing handle on grinding tool, have the advantage that structure is simple, easy to use, fixed bar is provided with spring, bearing established by spring, its Main Function provides certain pretightning force to grinding tool, and bearing is mainly convenient to grinding tool and is rotated.
