Description
Technical field
Flange field is the utility model is related to, is especially a kind of flange opener.
Background technology
Flange, flange flange disk or bead are called, are widely used in the import and export of equipment.Due to installed in end face of flange
On pad it is easy to aging, therefore in use for some time, it is necessary to flange be opened, to be changed to pad.Traditional side
Method is mainly opened flange by instruments such as flat mouth screwdriver or crowbars, because crowbar or screwdriver do not have on flange
The fulcrum of effect, it is very easy to skid, whole operation process is not only cumbersome, wastes time and energy, and easily causes the sealing of flange
Surface damage, cause burr and deeper cut occur, increase many troubles to follow-up overhaul plan sealing surface, also for equipment from now on
Operation bring potential safety hazard, or even need to change accessory because sealing surface cut is too deep sometimes, virtually increase maintenance into
This.
Utility model content
It is a kind of simple to operate, time saving and energy saving that the technical problems to be solved in the utility model is to provide, and is opening the mistake of flange
Cheng Zhong, it can effectively avoid the flange opener of flange seal surface damage.
Technical solution of the present utility model is to provide a kind of flange opener with following structure, including pedestal,
Threaded mandrel, the one or six prism, the two or six prism and disk, threaded mandrel top are rotatably connected with pedestal, the one or six rib
Post is arranged on threaded mandrel top and is integral with threaded mandrel coaxial line, the one or six prism with threaded mandrel, the two or six rib
Post offers the internal thread being screwed into for threaded mandrel along own axes direction, and disk is arranged on the two or six prism bottom and with second
Six prism coaxial lines, disk are integral with the two or six prism.
Flange opener described in the utility model, wherein, it is rotatably connected and refers to pedestal at the top of the threaded mandrel,
Open up fluted in base bottom surface, be provided with boss at the top of threaded mandrel, boss be located in groove, and boss top is sphere, spiral shell
Line push rod is contacted by sphere with pedestal point.
Flange opener described in the utility model, wherein, it is provided with some hemisphere on base top surface and disk bottom surface
Shape is raised.
After above structure, compared with prior art, the utility model flange opener has advantages below：Passing through will
Two the utility model are symmetricly set between flange and equipment, are then rotated the one or six prism using spanner, are opened flange
Device gradually extends along own axes, so as to reach the purpose that flange is opened on top.This structure of the present utility model is led to prior art
Cross screwdriver or crowbar is opened flange and compared, operation is more simple, and whole process is very time saving and energy saving, and is opening flange
During, the damage of flange sealing surface will not be caused, is effectively saved the cost of overhaul.
Threaded mandrel is contacted by sphere with pedestal point, can effectively reduce threaded mandrel in rotary course, with pedestal it
Between frictional force, operation is got up more light.
During opening flange on top, hemispherical projections can increase the frictional force that the utility model contacts with equipment, prevent
Skid.
Brief description of the drawings
Fig. 1 is the main view cross section structure diagram of the utility model flange opener.
Embodiment
The utility model flange opener is described in further detail with reference to the accompanying drawings and detailed description：
As shown in figure 1, in this embodiment, the utility model flange opener includes pedestal 15, threaded mandrel
17th, the one or six prism 16, the two or six prism 19 and disk 18.The top of threaded mandrel 17 is rotatably connected with pedestal 15；First
Six prisms 16 are arranged on the top of threaded mandrel 17 and are one with threaded mandrel 17 with the coaxial line of threaded mandrel 17, the one or six prism 16
It is overall；Two or six prism 19 offers the internal thread being screwed into for threaded mandrel 17 along own axes direction；Disk 18 is arranged on
The bottom of two or six prism 19 is simultaneously integral with the coaxial line of the two or six prism 19, disk 18 with the two or six prism 19.
The top of threaded mandrel 17 is rotatably connected using following structure with pedestal 15：Opened up on the bottom surface of pedestal 15 fluted
14, the top of threaded mandrel 17 is provided with boss 12, and boss 12 be located in groove 14, is sphere 11 at the top of boss 12, threaded mandrel
17 are contacted for 15 points by sphere 11 with pedestal.Threaded mandrel 17 is contacted for 15 points by sphere 11 with pedestal, can effectively reduce screw thread
Push rod 17, with the frictional force between pedestal 15, makes operation get up more light in rotary course.
In order to increase the frictional force that the utility model contacts with equipment, prevent from skidding, the top surface of pedestal 15 and the bottom surface of disk 18
On be provided with some hemispherical projections 13.
In use, two the utility model flange openers are symmetricly set between flange and equipment first, then make
The one or six prism 16 is rotated with spanner, flange opener is gradually extended along own axes, so as to reach the purpose that flange is opened on top.
This structure of the present utility model is compared with prior art opens flange by screwdriver or crowbar, and operation is more simple, entirely
Process is very time saving and energy saving, and during flange is opened, will not cause the damage of flange sealing surface, is effectively saved inspection
Accomplish this.
The utility model it is compact it is easy to carry, use simple, cheap, rapid operation, safe, versatile.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical scheme of utility model is made, all should fall into the scope of protection of the utility model.
