card sets Note the use of hose fittings

Sleeve type hose connector has a simple structure , easy to use and do not have the advantages of welding . But in the high-pressure Hydraulic pipe fittings, if the improper operation will often cause leakage , affecting its widely used. After years of practice I summed up some experience , and achieved good results. Card sets of pipe joints mainly by a 24 degree taper hole connector body 1, with a sharp inner edge of the card sets 2 and play the role of compression nut 3 compression of three parts . Tighten the nuts 3:00 , lined butterfly valve ferrule 2 is advanced 24 degree taper hole and subsequently deformed, so that the card with Hydraulic hose fittings body cone sleeve forming spherical contact seal ; Meanwhile , the card edge embedded steel inner sleeve 4 the outer wall of the outer wall of the pressure out a ring groove , which play the role of a reliable seal . The best choice for stress relief annealing steel pipe 20 # fine extubation , it is a good card kit blade embedded in the outer surface of steel pipes , play a reliable seal.
