Card sets of valve in our country developed in recent years, the connection and sealing principle of it is that when the screw nut, card sets of pressure, the blade is biting into the tube outer wall and card sets of male cone and cone closed and joint under pressure, and thus can be reliably prevent leakage.
USES:
Card card sets of valve and pipeline in a set of links, prevent leakage, metal.Card sets of valve is widely used in petroleum, chemical, natural gas, power station, metallurgy, national defense scientific research and other fields.
Features:
1) small size, light weight, simple structure, disassembling easy;
2) connect the relay is strong, wide use, resistant to high voltage (1000 kg/cm2), high temperature (650 ℃) and impact vibration;
3) can be a variety of materials, suitable for corrosion protection;
4) the processing accuracy is not high;
5) easy to high altitude installation.
