Ball valve structure principle: 1. The ball valve is not limited by the installation direction, and the flow direction of the medium can be arbitrary. The fluid resistance is small, and the full-bore ball valve basicall...
The opening and closing part of the ball valve is a sphere with a circular channel, which rotates around an axis perpendicular to the channel, and the sphere rotates with the valve stem to achieve the purpose of opening ...
During use, if the system pressure is too large, the safety valve will jump. The pressure regulating valve can set the pressure value. When the pressure is higher than this value, the valve opens, and when the pressure i...
Electric gate valve is a kind of linear motion valve, which is matched with Z-type multi-turn actuator, and there are switch type and intelligent type. This valve is simple to operate and is a common opening and closing ...
The purpose of the globe valve is as follows: Globe valves can be used in most media process systems. Various forms of globe valves have been developed to meet various uses in petrochemical, electric power, metallurgy, u...
1. StructureWhen the installation space is limited, attention should be paid to the selection. The gate valve can be tightly closed with the sealing surface by the medium pressure, so as to achieve the effect of no leaka...
