Stainless steel fittings fittings sealing principle

Stainless steel fittings ferrule tube fitting the basic structure of the body made ​​of stainless steel fittings , card sets, compression nut composed of three basic parts ( Fig. 1 >, where stainless steel fittings ferrules are key parts .
Stainless steel fittings ferrule is a hill -side with the inner edge of the metal ring , it has good rigidity , hardness and toughness. Stainless steel Hydraulic tube fittings ferrule surface hardness is generally 5 to 63 , hard layer depth of 05 and II, the hardness of the substrate between 9891 ~ 96 . Stainless steel fittings card sets in the assembly process, when tighten the compression nut , stainless steel fittings ferrule axial force, pushed the connector body 24 " tapered bore , the card sets in the radial direction under the action of radial force contraction, so that the inner sleeve and the outer tube cut edge an annular groove is formed , as shown in Figure 2, segment 0 of the annular groove depth of about 3 to 0,501,111 , formed stainless steel ferrule and the pipe joint between the outer wall seal; Meanwhile , the card connector body Gunn outer wall 24 . tapered hole is completely tightly bonded together to form a sleeve between the joint body tapered bore sealing tape . 6 above in Figure 2 . " , 6 two a sealing tape to complete the sealing of a tube . From stainless steel Hydraulic pipe fittings ferrule tube fitting sealing principle can be seen, stainless steel fittings ferrule manufacturing quality is good or bad in itself as well as sealing tape ", 6 are in good form is related to the pipe stainless steel fittings for leaks of the key issues .
