Position opens up fluted, offers fixation hole, second method on the connector at position corresponding with the threaded hole
It is provided with filter screen on the left of blue inner via hole, is provided with gasket on the left of the filter screen.
Further, the first flange and second flange outer surface are coated with anticorrosive paint.
Further, the ring flange is fixedly connected with first flange, second flange, and is uniformly opened on the ring flange
Equipped with mounting hole, installation threaded rod has been connected through a screw thread in the mounting hole.
Further, fixed thread bar has been connected through a screw thread in the threaded hole.
Further, the depth of the fixing groove be greater than connection connector length, and the fixing groove in and connector
Junction is provided with rubber pad.
Further, contact ring is provided on the left of the gasket.
The beneficial effects of the invention are as follows：A kind of pipeline connection High-sealing-performflange flange according to the present invention, passes through setting
Fixing groove and connector protrude into connector in fixing groove in connection, with link block and groove, so that connector exists
Fixing groove is not in position rotation, is fixedly connected with first flange with second flange by being fixedly connected for ring flange, passes through
Threaded hole, fixation hole and fixed thread bar cooperate, and positioning further is fixed to connector, because of the extension of connector, so that
Connection gap lengthens when pipeline connects, and by the way that gasket is arranged, considerably increases the leakproofness of flanged joint, the present invention has knot
Structure design is rationally, sealing effect is good and structural strength is high.

Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Fig. 1-Fig. 3 is please referred to, the present invention provides a kind of technical solution：
A kind of pipeline connection High-sealing-performflange flange, including first flange 1, second flange 2, the first flange 1 and the second method
Orchid 2 is fixedly connected by ring flange 3, and the first flange 1,2 lumen centers of second flange offer through-hole 4, the through-hole 4
Outside offers fixing groove 5, protrudes into connector 8 in fixing groove 5 in connection, 5 inner cavity of fixing groove is evenly arranged with company
Connect block 6, connector 8 in that is not in that position rotates in fixing groove, is uniformly provided with threaded hole 7, institute on the left of the fixing groove 5
