A valve is a device in a fluid conveying system that controls the flow rate, direction, pressure, temperature, etc. of the fluid medium. It is a device that allows the medium (liquid, gas, powder) in piping and equipment to flow or stop and control its flow rate.
Valves can be divided into the following categories based on their functions:
Globe valve: used to completely shut off or open the flow of fluid.
Regulating valve: used to control the flow rate of fluid.
Check valve: used to prevent fluid backflow.
Diverter valve: used to divert fluid to multiple pipelines or equipment.
Overflow valve: used to prevent excessive fluid pressure.
Valves can be divided into the following categories based on their structure:
Rotary valve: The valve core changes the cross-sectional area of the flow channel through rotational motion.
Straight stroke valve: The valve core changes the flow channel cross-section through linear motion.
Angular stroke valve: The valve core changes the flow channel cross-section through angular line movement.
Valves can be classified into the following categories based on their materials:
Metal valve: a valve made of metal materials.
Non metallic valves: Valves made of non-metallic materials, such as plastic valves, rubber valves, etc.
Valves are widely used in industries, construction, agriculture, transportation, and other fields. In the industrial field, valves are used to control the fluid flow of production processes, such as water, steam, oil, gas, etc. In the field of construction, valves are used to control water supply, drainage, heating, ventilation and other systems inside buildings. In the field of agriculture, valves are used to control fluid flow during agricultural production processes, such as irrigation, drainage, sprinkler irrigation, etc. In the field of transportation, valves are used to control the fluid systems of transportation vehicles, such as cars, airplanes, ships, etc.
Valves are important components in fluid transportation systems, and their performance directly affects the safe, reliable, and efficient operation of the fluid system. Therefore, the selection, installation, maintenance, and other work of valves need to be strictly carried out in accordance with relevant specifications. |
