The three-flange that described outlet conduit fastens through bolt is connected with solid powder discharge pipe.
In course of normal operation, solid powder gradually can fill up break-in cushion chamber and adapter cavity in course of conveying successively,
Form relative dead zone.Solid powder in carrying at a high speed along inlet pipeline passes through the process of break-in discharging opening and outlet conduit
In, original conveying direction can change.Different from common elbow, solid powder will not during conveying direction change
Directly contact with the tube wall of conveyance conduit, but directly contact with the powder piled up in break-in cushion chamber and adapter cavity, from
And avoid the abrasion to tube wall for the solid powder.Therefore, the design of break-in discharging opening, break-in cushion chamber and adapter cavity is not
Only can realize the change of solid powder direction of motion under higher transporting velocity, and solid powder can be prevented effectively from
Material directly contacts and worn out tube wall with pipeline outer wall at turning point, thus extends the service life of pipeline.
Further, using standard seamless steel pipe, its easy buying, processing technology is ripe, effectively reduces and is manufactured into
This.
Further, connected by flange, can make install, overhaul and change convenient and swift.
