Abstract
When people install pipelines, the pipelines need connecting by a flange plate usually. At present, the used flange plates all have the same defect of inconvenient installation. The utility model provides a quickly mounting-dismounting type flange plate which is characterized in that a connecting hole of a bolt is outwards provided with an opening in the radial direction and is provided with a safety hole, and therefore, a bolt can be directly put in a screw hole from the opening. The mounting time, the connecting time and the dismounting time of the flange plate are greatly shortened.
Description
The utility model relates to a kind of piping flange dish, is used for the connection between the pipeline.
People are when carrying out piping erection, and being connected usually between pipeline and the pipeline will be used flange plate, although the structural type of flange plate is many, all has a common shortcoming, promptly connect inconvenient between the flange plate.Particularly in the landform more complicated, when pipeline need repeatedly bend, especially like this, trouble is installed, the time that needs is long.
The purpose of this utility model is to provide a kind of quick assembling ﹠ disassembling flange plate of novel structure, adopts this flange plate, and it can shorten the assembling of flange plate significantly, connects the take-down time.
The method that the utility model adopted is to change original flange plate to connect the form of screw and achieve the above object.
The utility model is owing to adopt this new form.Can shorten assembling, connection, the take-down time of flange plate significantly, can replace present widely used welded flange, welding neckflange, loose flange, can reduce production costs significantly.
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Fig. 1 is the structural representation of flange disk body 1
Fig. 2 is an installation diagram of the present utility model
The utility model comprises flange disk body (1), SEALING FITTING (2), central authorities at flange disk body (1) have pipeline attachment hole (3), it is characterized in that: also have insurance hole (4) and bolt connecting hole (5) on the flange disk body (1), and the radially external opening of bolt connecting hole (5).Changed originally when pipe laying, because bolt connecting hole opening not need screw out the nut on the bolt, the mode that screw rod is penetrated from bolt connecting hole again, and bolt directly can be put into bolt connecting hole (5) by opening.Insurance hole (4) then be of adopting that machinery tools process with bolt connecting hole (5) in same garden in the heart, its diameter can steadily place bolt greater than the seam of bolt connecting hole diameter.
When connecting between the pipeline, the SEALING FITTING on the flange plate (2) is welded in respectively on the pipe that needs to connect, lightly rotates flange plate and make bolt connecting hole (5) opening unanimity, again bolt is put into and screwed nut by opening.During dismounting, only need unscrew the insurance hole (4) that bolt head just can expose on the flange plate after nut 2～3 teeth and can take out bolt, mounting flange is separated.Owing on flange plate, designed insurance hole (4), make bolt when screwing state, become firm the connection with flange plate, even vibration is arranged, can not come off yet.
Claims (1)
1, the utility model relates to a kind of quick assembling ﹠ disassembling flange plate, it comprises flange disk body (1), SEALING FITTING (2), central authorities at flange disk body (1) have pipeline attachment hole (3), it is characterized in that: also have insurance hole (4) and bolt connecting hole (5) on the flange disk body (1), and the radially external opening of bolt connecting hole (5).
