Instrument pipe valves are a key component of fluid control systems, mainly used to control the flow, stop, change direction, and other operations of fluids. Common fluid pipe valves include valves, filters, flow meters, pressure gauges, etc.
Valve is a commonly used type of instrument pipe valve, which can control the flow and direction of fluid by opening or closing. According to different working principles, valves can be divided into different types such as globe valves, gate valves, ball valves, butterfly valves, etc. For example, gate valve is a commonly used valve that cuts off fluid in pipelines by lifting the gate. It has a simple structure, good sealing performance, and is suitable for high flow and high pressure pipeline systems. Ball valves control the opening and closing of fluids by rotating the ball. They are flexible in operation, have good sealing performance, and are suitable for high viscosity fluids and corrosive media. Butterfly valve is a disc-shaped valve that controls fluid flow by rotating a disc. It has a compact structure, small volume, and is widely used under low pressure and moderate temperature conditions. Check valves can prevent fluid backflow and only allow fluid to flow in one direction. They play a role in protecting equipment and preventing pressure fluctuations in pipeline systems.
In addition to valves, filters are also an important component of fluid pipe valves. Filters are used to remove impurities and particulate matter from fluids to protect fluid piping valves and other piping equipment from wear and blockage. According to different filtering principles, filters can be divided into different types such as surface filters, depth filters, bag filters, etc.
In addition, flow meters are used to measure the flow rate of fluids and can be used to monitor and control fluid flow rates. According to different measurement principles, flow meters can be divided into different types such as throttling, vortex street, ultrasonic, etc. Pressure gauges are used to measure the pressure of fluids in pipelines and can be used to monitor and control fluid pressure. According to different measurement principles, pressure gauges can be divided into different types such as spring type, resistance type, capacitance type, etc.
In addition, instrument pipe valves also include some pipeline connectors, such as elbows, flanges, pipe joints, etc., which are used to connect different components of the pipeline system and have the characteristics of withstanding pressure, sealed connections, and easy disassembly.
Overall, instrument piping valves play an important role in fluid control systems, ensuring the safety and stability of fluid flow in pipelines. Different types of instrument pipe valves have different characteristics and applicable scenarios, and need to be selected and applied according to specific usage environments and requirements.
