Plate/ring sealing device is facilitated to open or close.
It is for technical solution used by realization the purpose of this utility model:
A kind of connection structure of pipeline, the flange including two for being welded on the pipeline of docking, is mounted on two methods
Board-like or ring type sealed inserted piece between orchid, be formed on the excircle of the flange it is multiple be evenly arranged it is outwardly directed
Support plate, has in each support plate bolt to install connecting hole, and the bolt with stop collar installs connecting hole by the bolt
By two corresponding support plate connections, the other end of the bolt with stop collar is threadedly coupled double nut；The sealed inserted piece
Two sides and two flanges between have washer respectively；A lug is formed on the excircle of the sealed inserted piece, on the lug
There is bolt through hole, can be used for the connection bolt of flange by being connected afterwards with attaching nut.
The support plate is steel plate, the support plate and flange welding.
The support plate is rectangular-shaped body plate.
The sealed inserted piece of the utility model is attached by bolt hole thereon with flange, the support plate with flange welding
On bolt rise load-bearing effect, by bolt it is elastic can be convenient open or close sealing insert.

Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Referring to shown in figure, a kind of connection structure of pipeline, the flange including two for being welded on the pipeline of docking, i.e.,
First flange 3 and second flange 4, board-like or ring type the sealed inserted piece being mounted between two flanges, the outer circle of the flange
It is formed with multiple outwardly directed support plates 6 being evenly arranged on week, has bolt that connecting hole, packet are installed in each support plate
The through-hole 15 in first flange and the threaded hole in second flange 14 are included, the bolt 5 with stop collar (set) 8 passes through the bolt
Connecting hole is installed to connect two corresponding support plates, the other end of the bolt with stop collar is threadedly coupled double nut 13；
There is washer 16 respectively between the two sides of the sealed inserted piece and two flanges；Formation one is convex on the excircle of the sealed inserted piece
Ear has bolt through hole on the lug, and can be used for the connection bolt 17 of flange, (threaded hole is non-by flange bolt connecting hole
Threaded hole) 10 and the bolt through hole after, be connected with attaching nut 18.
Wherein, the support plate is steel plate, the support plate and flange welding, and the support plate is rectangular-shaped body plate, branch
Fagging is uniformly distributed in flange center's line both sides span centre.
Wherein, the sealing surface of the flange is fine groove waterline sealing surface Ra 6.3-12.5um,
Wherein, the bolt hole on the flange should be evenly distributed with, and be straddled in flange center's line both sides, wherein in the flange
After being welded to connect with pipeline 100, it to be welded with triangle stiffener plate 7 between flange and the outer wall of pipeline, reinforces branch to realize
Support.
Wherein, the sealed inserted piece is cyclic annular or plate, can be referred to as plate 2, slotting ring 1, and plate 2, slotting ring 1 are distinguished
One lifting lug, plate lifting lug 21, slotting ring lifting lug 11 have a mounting hole respectively above, such as plate mounting hole 22, slotting ring mounting hole
12, the plate, slotting ring lifting lug mounting hole among two bolts hole of two panels flange, and it is solid by the bolt of installation
Fixed, one end of the flange and pipeline weld, and pass through the branch of bolt and welding on flange between the flange and flange
Bolt on fagging is fixed.When changing the outfit plate/slotting ring, completed by following steps:
1) 180 ° of screw bolt and nut on lower flange is unloaded on the direction that plate/slotting ring pulls out.
2) unscrew remaining 180 ° of screw bolt and nut on flange, unscrewing rear bolt end face should be except nut end face.
3) unscrew the load-bearing bolt in four support plates counterclockwise, and do not adjust double nut.
4) when replacing plate/ring washer as needed, it is ensured that plate/ring lifting lug is located among two bolts hole.
5) it tightens the load-bearing bolt in four support plates clockwise and does not adjust double nut.
6) 180 ° on the flange being removed of screw bolt and nut is reinstalled.
7) all screw bolt and nut are tightened by the general industry specification of washer in place is sequential.
The utility model can bolt be quick and convenient opens or closes plate/slotting ring by opening, and is particularly suitable for heavy caliber
It is frequently necessary to the plate/slotting ring pipeline opened or closed, and easy to dismantle.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
