Technical field
This utility model is related to flange technical field, specially a kind of compression type flange with sealing ring.
Background technology
Flange is widely used in the connection of industrial pipeline, and common flange is only capable of playing the effect of connection it is impossible to play close
Envelope acts on, and during flange connects and uses, in pipeline, the fluid media (medium) of flowing usually can overflow from the junction of flange,
Cause to reveal, affect normal work.In the prior art, in order to ensure sealing, often in the pipe joint of pipeline or plunger etc. even
Meet place, using gasket seal, and existing gasket seal adopts gum pad, asbestos pad etc. mostly, and sealing effectiveness is poor, and assembling is multiple
Miscellaneous, easily come off, service life is short, connect inconvenient, waste the set-up time, connection speed is slow, and increased the labor of operator
Fatigue resistance.
Utility model content

The problem of middle proposition.
This utility model adopts the following technical scheme that：
A kind of compression type flange with sealing ring, by upper flange body, boss, sealing device, screw, flange lock, close
Seal ring, groove, stepped hole, lower flange body, through hole, diaphragm seal, arc groove composition.
Described lower flange body upper end is connected with upper flange body.
It is provided with the arc groove of an annular between described lower flange body upper end and upper flange body, in arc groove, sealing ring is installed.
Described upper flange body is internally provided with through hole, and the upper surface of upper flange body is provided with boss.
Described lower flange body is internally provided with through hole, and the lower surface of lower flange body is provided with boss.
Described boss is internally provided with stepped hole.
Described step in the hole is provided with sealing device.
The bottom of described lower flange body is provided with the groove of an annular.
It is provided with diaphragm seal in described groove.
It is mounted on the flange lock of a U-shaped in the side wall of described upper flange body and lower flange body, flange lock lower end sets
A projection is had just to block in a groove, flange lock upper end is provided with a screwed hole, and screw thread in the hole is provided with screw.
