State first flange, the second flange.
Further, the first flange, the second flange both sides are respectively provided with bolt hole, and the full filament length screw rod can be worn
Cross the bolt hole.
Further, first nut, second nut, the 3rd nut are mating with the full filament length screw rod
Connection can block the first flange, the bolt hole in the second flange.
Further, first nut, second nut are arranged on one end of the full filament length screw rod, positioned at described the
Between one flange, the second flange, set close to the first flange.
Further, mutually locked between first nut and second nut.
Further, the full filament length screw rod stretch out on one end of the second flange be equipped at intervals with successively the 3rd nut,
Nut.
Further, first flange, described second described in the nut distending of the second flange both sides alternately are tightened
Flange.
Further, the angle between two sets of screw nut assemblies is in 90-180 °.
The beneficial effects of the utility model are：The swollen silk device of flange of the utility model solves medium pipeline big orifice valve
During replacement, valve passes in and out the problem of being clamped by flange, and convenient material drawing is easily achieved, and suitable for any place, can improve equipment
Installation exercise efficiency does not damage new valve and flange gasket, reduces security risk, cost-effective.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is a kind of structure diagram of the swollen silk device of Simple valve flange of the utility model.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
With reference to Fig. 1, Simple valve flange is swollen, and silk device includes screw nut assembly 1, first flange 7, second flange 8, spiral shell
Stem nut component 1 is made of the first nut 2, the second nut 3, the 3rd nut 4, full filament length screw rod 5, nut 6, for distending first
Flange 7 and second flange 8.
Screw nut assembly 1 includes two sets, is separately positioned on first flange 7, the both sides of second flange 8；By alternately twisting
1 distending first flange 7 of screw nut assembly, the second flange 8 of tight both sides.
Full filament length screw rod 5 can pass through first flange 7, the bolt hole 9 of second flange 8, convenient for distending first flange 7 and second
Flange 8.
First nut 2, the second nut 3, the 3rd nut 4 expire the 5 mating connection of filament length screw rod with described, and can block first
The bolt hole 9 of flange 7, second flange 8.
First nut 2, the second nut 3 are arranged on one end of full filament length screw rod 5, between first flange 7, second flange 8,
It is set close to first flange 7, first flange 7 can be propped up convenient for the first nut 2.
It is mutually locked between first nut 2 and the second nut 3, for the first nut 2, the second nut 3 and full filament length screw rod 5
Between mutually lock, while the first nut 2 can prop up first flange 7.
Full filament length screw rod 5 is stretched out on one end of second flange 8 is equipped at intervals with the 3rd nut 4, nut 6 successively, conveniently passes through
