Flange has the flange plate of being called or bead, it is a kind of connection set being widely used, to the requirement of strength of flange, be quite high, once flange damages, can impact work, flange is applied to when pipeline connects be found everywhere in daily life, yet flange exists the poor problem of join strength, hubbed clip-on-welding flange comprises flange body and neck platform, joint between neck platform and neck platform and flange body is easily damaged, to such an extent as to whole flange need to be replaced, and cost is high; And in transit, the neck platform of hubbed clip-on-welding flange easily collides with, be therefore necessary hubbed clip-on-welding flange to transform.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of hubbed clip-on-welding flange of anti-slip.
For achieving the above object, the utility model provides following technological scheme: a kind of hubbed clip-on-welding flange, comprise flange body and neck platform, described flange body is provided with through hole, described through hole is provided with internal thread, and described neck platform comprises neck end and the portion that screws being wholely set with neck end, described in the portion of screwing be provided with outside thread, described neck platform coordinates with through hole whorl, between described flange body and neck end, is provided with Sealing.
By adopting technique scheme, hubbed clip-on-welding flange is divided into neck platform and flange body two-part, in through hole in flange body, be provided with internal thread, on the rotary part of neck platform, be provided with outside thread, neck platform and flange body are coordinated and are fixed connection by screw thread rotation, when occurring that flange body or neck platform are damaged, only need to change broken parts, do not need whole flange all to change, greatly saved cost, extended the working life of flange simultaneously yet; In addition, between flange body and the neck end of neck platform, Sealing is set, strengthens the sealing between neck platform and flange body.
The utility model is further set to: described flange body is provided with a plurality of mounting holes, and described mounting hole is evenly distributed to be circularized, and described mounting hole two ends are provided with counter sink.
By adopting technique scheme, in flange body, be provided with a plurality of mounting holes, and mounting hole is evenly distributed to be circularized, convenient by bolt or screw, to being fixed between flange and pipe fitting, be connected, and at mounting hole two ends, be provided with counter sink, during installation, the head of the head of bolt or screw be placed on counter sink, can slow down bolt or the screw destruction to mounting hole, also strengthen aesthetic property simultaneously.
The utility model is further set to: described flange body and neck platform form by stainless steel.
By adopting technique scheme, the material of flange body and neck platform is stainless steel, be that hubbed clip-on-welding flange is made by stainless steel, because stainless steel has high mechanical properties, the features such as corrosion resistance, therefore the hubbed clip-on-welding flange of being made by stainless steel also has the features such as high mechanical properties and corrosion resistance, and while connecting for pipeline, stability and soundness are good.
The utility model is further set to: described Sealing is felt seal.
By adopting technique scheme, between flange body and the neck end of neck platform, Sealing is set, strengthen the sealing between neck platform and flange body, Sealing is preferably felt seal, the sealing of felt seal and soundness are compared general seal ring and will be got well, and be difficult for aging, long service life.
The utlity model has following advantage: flange is divided into flange body and neck platform two-part, adopt split type mounting flange, even while occurring that flange body or neck platform are damaged, only need to change broken parts, cost-saving, the while has also extended the working life of flange; In addition, in transit, flange can be split to transportation, damage is not easy to collide with.
Accompanying drawing explanation
