Abstract
The utility model discloses an integral manhole flange taking a flange plate as an integral manhole, in which the flange plate is sealed by a flange cover. The integral manhole flange is convenient and reliable in connection, and good in overall sealing effect. The integral manhole flange disclosed by the utility model is used for sealing an opening of a tank body, and comprises a flange plate and a flange cover, wherein the flange cover is used for sealing the flange plate; the edge of the flange plate is provided with a convex rim, bolt holes are correspondingly formed in the convex rim and the flange cover, and the bolt holes are through holes; the center of the flange plate is provided with an installing through hole; and the flange cover and the flange plate are connected through bolts, the bottom of the flange cover is provided with an extending part extending to the inside of the installing through hole of the flange plate, the extending part is of an inverted cone structure, and a sealing gasket is arranged between the flange cover and the flange plate. The bottom part of the flange plate is of an inverted cone structure, and the bottom end of the flange plate is welded on the opening of the tank body. The flange plate and the flange cover are connected through double-end bolts.
Description
Technical field
The utility model relates to pipeline installation fitting field, is specifically related to flange.
Background technology
The airtight containers such as tank body generally are provided with manhole flange, the seal request of manhole flange is higher, meanwhile, common manhole flange is very inconvenient when butt flange lid and flange, is mainly connecting bore structure unreasonable the causing of flange and blind flange.
The utility model content
Technical problem to be solved in the utility model is to provide for above-mentioned deficiency of the prior art the integer manhole flange that a kind of flange is integer manhole, for flange, by blind flange, seals, and it is easy to connect reliable, and integral sealing effect is good.
The utility model solves the technical scheme that its technical matters adopts: integer manhole flange, for the opening of sealed shell of tank, comprises flange and for the blind flange of sealing flange;
The edge of described flange makes flange, the corresponding bolt hole of offering on flange and blind flange, and bolt hole is through hole; The center of flange is manufactured with the installation through hole;
Above-mentioned blind flange and flange are bolted, and the blind flange bottom arranges and stretches to the extension that flange is installed the vertebral body structure in through hole, between blind flange and flange, packing seal is set.
Further: the bottom of above-mentioned flange is the vertebral body structure, and bottom is welded on the opening of tank body.
Further: above-mentioned flange is connected by thru-bolt with blind flange.
The utility model compared with prior art has the following advantages:
The utility model integer manhole flange, by the manhole flange dish in an integral body of tank body opening part welding, this flange is manufactured with the flange that is specifically designed to the butt flange lid, thus, bolt can be very convenient when mounting flange and blind flange, dismounting easily; Blind flange is made extension downwards, can failure-free by flangeseal; Finally by packing seal, realize better sealing.
