Valve connection type --- sleeve connection

The sleeve connection is only developed in China in recent years. Its connection and sealing principle is that when the nut is tightened, the ferrule is subjected to pressure so that the blade bites into the outer wall of the tube, and the outer conical surface of the ferrule is under pressure and joints. The inner surface of the cone closes, so it can reliably prevent leakage.

The advantages of this connection form are:
The
1, small size, light weight, simple structure, easy assembly and disassembly;

2, strong connection, a wide range of use, can withstand high pressure (1000 kg/cm2), high temperature (650 °C) and shock vibration

3, can choose a variety of materials, suitable for anti-corrosion;
The
4, the processing accuracy is not high; easy to install at high altitude.

At present, the card sleeve connection type has been adopted in some small-diameter valve products in China.
