The inboard card of described two flange plate is the plane of fitting mutually.
The centre of described two flange plate offers through hole, and described annular groove is between through hole and the flange hole.
The bolt head of described bolt is the pentagon bolt head.
The counterbore of described one of them flange plate cooperates with described bolt head or nut spline.
The purpose of this utility model also is to provide a kind of antitheft flange, thereby prevents that flange from being destroyed the enforcement theft by the lawless person.
The technological scheme that antitheft flange of the present utility model adopted is: a kind of antitheft flange, comprise flange plate, flange plate circumferentially offer flange hole, the place, aperture of described flange hole one side is provided with the counterbore that is used to hold bolt head or nut, offer annular groove on the card of opposite side, on this annular groove card of living in the flange hole periphery and the annular groove place have and be used for the applying plane that cooperatively interacts with another antitheft flange.
Described annular groove card of living in is the plane.
The centre of described flange plate offers through hole, and described annular groove is between through hole and the flange hole.
Be provided with seal ring in the described annular groove.
The utility model adopts the technological scheme of offering counterbore on flange hole, bolt head and nut sink in the counterbore, general extracting tool can't stretch in the counterbore, can only rely on special instrument just can dismantle, and has prevented that the lawless person from implementing theft by demounting bolt and nut; In addition, abandon the boss structure in the existing design, adopted the alternative structure of annular groove, the seal ring that can be provided with in the annular groove, when two flanges interconnected, two flange plate compressed seal ring mutually and realize sealing on the applying plane at annular groove place, and the applying plane that is in the flange hole periphery simultaneously guarantees between two flanges very close to each other substantially, the lawless person just can't implement theft by sawed-off connecting bolt, has improved the anti-theft effect of flange.
