Abstract

The invention relates to a quick coupling characterized in that said quick coupling used for the high temperature fluids in the pipe coupling systems comprises at least one of the gasket-free valve assembly (40), alternative valve assembly-1 (40-1), alternative valve assembly-2 (40-2) or alternative valve assembly-3 (40-3) in a plug and/or body member (10) and there are present a valve ball (44) providing the sealing for the high temperature fluids and/or composite fluids, which gives a combination of hardness, strength and corrosion resistance, a valve rear (43) designed considering the spherical structure geometry, a valve front (46), and the wing structures compatible with the plug and/or body member (10) and also suitable for the flow rate.

IPC Classes  ?

• F16L 37/23 - Couplings of the quick-acting type in which the connection is maintained by means of balls, rollers, or helical springs under radial pressure between the parts by means of balls
• F16L 37/407 - Couplings of the quick-acting type with fluid cut-off means with fluid cut-off means in only one of two pipe-end fittings with a lift valve being opened automatically when the coupling is applied the lift valve being of the ball type
• F16L 37/33 - Couplings of the quick-acting type with fluid cut-off means with fluid cut-off means in each of two pipe-end fittings at least one of two lift valves being opened automatically when the coupling is applied the lift valves being of the ball type
