This utility model is further arranged to: described slot is positioned at the bottom position of recess sidewall.
This utility model is further arranged to: described anticorrosion blank flange is removably connected by bolt with anti-corrosion pipeline.
The beneficial effects of the utility model: this utility model adds with ladder mouth in traditional blank flange card
Groove, then in groove, setting area extends to the corrosion protective lining on ladder mouth, and corrosion protective lining have employed high intensity, Gao Fang
The polytetrafluoroethylmaterial material of corruption is made, when anticorrosion blank flange and the mutual compact siro spinning technology of anti-corrosion pipeline, due to corrosion protective lining
Axial depth more than the degree of depth of ladder mouth, so ladder mouth and the difference in internal diameters of corrosion protective lining and the space that produces is corrosion protective lining
Pressurized generation creep diffusion provides and utilizes space, and the anticorrosion at ladder mouth is served as a contrast by the retention Hp prominent to the end face of anti-corrosion pipeline
In occur the direction of creep diffusion to play the role of positioning, therefore make blank flange and anti-corrosion pipeline be formed when being mutually butted closely,
Contact surface is big, the anticorrosion of rigidity connects, and not only preserving and sealing is effective, and anti-corrosion life increases.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
As shown in Figures 1 and 2, a kind of anticorrosion blank flange, it is connected, including flange body 1, institute with anti-corrosion pipeline 5 adaptation
State the card being connected with anti-corrosion pipeline 5 in flange body 1 and be provided with the internal diameter groove 11 more than anti-corrosion pipeline 5 internal diameter, described recessed
Groove 11 is provided with stair-stepping ladder mouth 111, and it is described that described anticorrosion blank flange also includes using polytetrafluoroethylmaterial material to be poured into
Groove 11 is interior and extends to the corrosion protective lining 2 on ladder mouth 111, and the thickness of the corrosion protective lining 2 at described ladder mouth 111 is higher than rank
The degree of depth of ladder way 111, and its external diameter more than groove 11 internal diameter and less than the internal diameter of ladder mouth 111；On described ladder mouth 111 with
Be provided with retention Hp 1111 at the knuckle of groove 11, described retention Hp 1111 along the axis direction of flange body 1 to anti-corrosion pipeline 5
End face highlights, and described corrosion protective lining 2 is provided with the location division 21 contacted with retention Hp 1111 adaptation；Described anticorrosion blank flange with
Anti-corrosion pipeline 5 is removably connected by bolt 4.
This utility model adds the groove 11 with ladder mouth 111 in traditional blank flange card, then recessed
In groove 11, setting area extends to the corrosion protective lining 2 on ladder mouth 111, corrosion protective lining 2 have employed high intensity, high anti-corrosive properties poly-
Tetrafluoroethene material is made, when anticorrosion blank flange and anti-corrosion pipeline 5 mutual compact siro spinning technology, and axial due to corrosion protective lining 2
The degree of depth more than the degree of depth of ladder mouth 111, so ladder mouth 111 and the difference in internal diameters of corrosion protective lining 2 and the space that produces is anticorrosion lining
In 2 pressurized generation creeps diffusions provide and utilize space, the prominent retention Hp 1111 of end face to anti-corrosion pipeline 5 is to ladder mouth
The direction that corrosion protective lining 2 at 111 occurs creep to spread plays the role of positioning, and therefore makes anticorrosion blank flange and anti-corrosion pipeline 5 phase
Formed during docking closely mutually, contact surface anticorrosion big, rigidity connects, and not only preserving and sealing is effective, and anti-corrosion life
Increase.
As in figure 2 it is shown, the sidewall of described groove 11 is provided with slot 112, described corrosion protective lining 2 is by slot 112
Card is embedded in described groove 11, and corrosion protective lining 2 can be played the role of positioning by slot 112, consolidates both combinations.Further, institute
State slot 112 and be positioned at the bottom position of groove 11 sidewall.
As in figure 2 it is shown, curved of described retention Hp 1111 is prominent, arcwall face is smoother, and existing positioning action again will not
Corrosion protective lining 2 at ladder mouth 111 is damaged.Further, described retention Hp 1111 projecting height is ladder mouth 111 degree of depth
Half.
As it is shown in figure 1, be coated with anticorrosive coat 3 on described flange body 1 outer surface, described anticorrosive coat 3 is that aqueous inorganic is rich
Zinc enamelled coating.Flange body 1 outer surface coated anti-corrosion layer 3, can prevent the corrosion of outer bound pair blank flange, thus extend blank flange
Service life.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and modification, above-mentioned vacation
If these improve and modification also should be regarded as protection domain of the present utility model.
