[0046] How to use quick connectors for blast furnace stave pressure test
[0047] The method for using the quick connector for blast furnace stave pressure test is characterized in that it comprises the following steps:
[0048] a. Clean up the dust and oil stains on the stave water pipe 9, and use a grinder to smooth the burrs and flashes of the nozzle;
[0049] b. Insert the connecting piece 3, the crimping sleeve 4 and the rubber hose 5 into the cap 2, so that the connecting piece plate is in flat contact with the cap 2, and the other end of the rubber hose 5 is connected to the pressure test pump.
[0050] c. Insert a rubber gasket 6 between the disc of the connector in the pipe cap and the end of the blast furnace stave water pipe to be pressure tested;
[0051] d. Put the lining ring 7 into the casing 1, and make one end of the U-shaped groove in front;
[0052] e. Rotate the casing 1 and the inner lining ring 7 into the cap 2, and it is advisable to lightly contact on...
