The above-mentioned expansion joint for blast furnace slag flushing waterpipe, is provided with rubber between described import guide shell and outlet guide flow cartridge
Sealing shroud, one end of rubber sealing boot docks with import guide shell, the other end of rubber gasket and outlet guide flow cartridge rebate
Close.
The above-mentioned expansion joint for blast furnace slag flushing waterpipe, is provided with the company affixed with suction flange outside described suction flange
Acting flange, adpting flange is provided with the inspection hole of L-shaped, checks that the cavity between tail end and corrugated tube and first guide shell in hole is even
Logical, check that the entrance point in hole is provided with inspection hole plug.
The above-mentioned expansion joint for blast furnace slag flushing waterpipe, the described affixed suction flange of adpting flange, import guide shell
Entrance point and adpting flange seam, the port of export of outlet guide flow cartridge and outlet(discharge) flange seam.
The above-mentioned expansion joint for blast furnace slag flushing waterpipe, described packing seal puts and is provided with filler inlet, and filler is noted
Entrance is provided with feeding port plug.
This utility model is carried out for the problem solving blast furnace slag quenching water expansion joint for pipeline precipitated carbonate silting corrugated tube
Improving, arrange the flexible guide shell structure of sealing inside expansion joint, described structure neither affects the compensation of expansion joint, again can be real
Now seal, it is ensured that medium does not enter between guide shell and corrugated tube.Such that make life-time service also not have carbonate deposition
The drawback of fouling silting corrugated tube, it is ensured that the reliability of expansion joint work.Make regular check on the reality of corrugated tube the most for convenience
Border situation, arranges inspection hole, can make regular check on bellows interior state by opening inspection hole plug, and make place in time
Reason.Use this utility model that expansion joint can be avoided to compensate inefficacy too early, saved production cost, alleviate workman's replacing and dispatch workers to do on-site repairs
Labor intensity.
