Pipeline connecting ring type and card type what is the difference?
PVC pipe ring pressure connection, is a kind of cold extrusion by means of pipes and pipe fittings connection sealing way, it is the bell will advance a sealing ring pipe insert, from the external connection section of the socket to put pressure on the week. Pressing, connection socket together with the insertion of the pipe together under the concave deformation after locking the lock, so as to realize the effective connection method of sealed pipes and fittings.
1 compression ring joint
The ring pressure connecting pipe is inserted into the socket of the pipe with a rectangular sealing ring in advance, and the stable section and the sealing section of the socket are pressed by the outside. Pressing, stable segment socket insert pipe together with concave deformation after being locked with locking; movement and deformation in the cavity to fully fill the gap between the pipe and pipe sealing material makes the pressure of the sealing section at both ends, so as to achieve effective sealing pipe and fittings.
2 card type connection
Card type is connected with the sealing ring socket pipe connecting pipe, with special tool press and a pipe connection sealing and fastening function. The basic composition of press fitting is a special shape at the end of >U type O type sealing ring is arranged in the groove of the pipe connector. When assembled, the stainless steel pipe is inserted into the pipe, using special tool pressure seal sealing pressure, sealing pipe, pressure part of the tube is extruded into hexagonal, thus forming the corresponding connection strength, at the same time as the ring compression deformation of the sealing function. The pipe fitting cost is low, the project installation is simple, the construction speed is quick.
