Valve types mainly include the following categories:
Diode valves, thyristor valves, and IGBT valves: These valves consist of power electronic equipment and their accessories, and can provide unidirectional or bidirectional conductivity. They are typically used for flexible transmission in power systems.
Ground valves ": including gates and throttle valves. Gate valves block or connect the flow of media through the movement of gate valves, and are suitable for fire pump exhaust pipes, suction pipes, etc. D. Other matters Rotary valves open and close by rotating a disc around the valve axis, and their application range is similar to that of valves.
Regulating valve ": such as pressure reducing valve and throttle valve used to regulate the pressure and flow rate of the medium. The pressure reducing valve adjusts the pressure by the pressure difference generated by the different cross-sectional areas at both ends of the piston, while the throttle valve adjusts the flow rate by changing the throttle section.
One way valve: including a one-way valve and a backflow fuse used to prevent medium backflow. The one-way valve is driven by its own weight and average pressure, and the reflux fuse is a combination of two independent one-way valves and a safety drain valve.
Type of safety valve: used for overpressure protection. When the pressure of the medium in the equipment or pipeline exceeds the specified value, the safety valve releases the medium outside the system to prevent excessive pressure. This type of valve is commonly used in gas fire extinguishing systems and automatic sprinkler fire extinguishing systems.
These valves have a wide range of applications in related fields, ensuring the normal operation and safety of the system.
