In the sealing plane flange being provided with one side dual-cavity of the present invention, the first annular groove of above-mentioned flange body and second
Cannelure is respectively equipped with the first " O " RunddichtringO and second " O " RunddichtringO, for the flange of heavy caliber and high pressure
Body, such sealing means further increase described in be provided with the sealing property of sealing plane flange of one side dual-cavity, can
High by property.
Be additionally provided with pressure testing hole on the end face of above-mentioned flange body, and this pressure testing hole be positioned at first annular groove and the second cannelure it
Between, may utilize this pressure testing hole and be provided with one side to described between above-mentioned first " O " RunddichtringO and second " O " RunddichtringO
The sealing plane flange of dual-cavity carries out the water pressure test, can realize to the sealing plane method being provided with one side dual-cavity described in each
Orchid carries out monomer sealing property detection.
As a kind of improvement to technical scheme of the present invention, the cross section of above-mentioned first annular groove and the second cannelure is all in square
Shape.
As a kind of improvement to technical scheme of the present invention, the cross section of above-mentioned first annular groove and the second cannelure is all in ladder
Shape.
As a kind of improvement to technical scheme of the present invention, the cross section of above-mentioned first annular groove and the second cannelure is all in arc
Shape.
In technical scheme of the present invention, Cross section Design by above-mentioned first annular groove and the second cannelure is rectangle, trapezoidal
Or arc, both facilitated processing and assembling, also can guarantee that first " O " RunddichtringO, second " O " RunddichtringO each served as sealing
Effect, thus improve sealing effectiveness.
As a kind of improvement to technical scheme of the present invention, above-mentioned flange body uses fiberglass to make.
It in addition, in technical scheme of the present invention, all is not specifically noted, all can be by using the routine in this area
Means realize the technical program.
Therefore, the invention has the beneficial effects as follows and provide a kind of sealing plane flange being provided with one side dual-cavity, this is provided with one side
