Overview

Product Details

A flow valve refers to a type of valve that achieves constant fluid flow by adjusting the opening of the valve port or the position of the corresponding valve core. In industrial production and automation control, flow valves are widely used in fluid control systems in industries such as hydraulic, pneumatic, and heating. It can maintain a certain value of hydraulic system flow to achieve precise flow control or energy regulation, ensuring the reliability and stability of the entire system.

classification

1. Differential pressure constant flow valve: also known as a throttle valve, it restricts the flow rate of the medium through the throttle port and the structural size of the throttle port or hole, so that the fluid experiences a certain pressure drop when passing through the valve. Common differential pressure constant flow valves include throttle valves, orifice plates, fuel injectors, etc.

2. Flow balanced constant flow valve: It maintains a constant system flow by utilizing the principle of mechanical force balance on the valve core or flow balance between flow control components. The most common flow balanced constant flow valves include extended arm type, double diaphragm type, three-way flow controller, etc.

3. Direct acting constant flow valve: It is a valve that uses a valve core that directly unloads or generates a reactive force to control the opening of the valve port, thereby maintaining a constant flow rate at the valve port. Common direct acting fixed flow valves include piston type fixed flow pumps, pressure buffers, spool type fixed flow pumps, etc.

4. Electromagnetic constant flow valve: It uses an electromagnet to control the position of the valve core, thereby achieving stable flow regulation. Electromagnetic constant flow valves are divided into electric, electro-hydraulic, and electro-hydraulic types, and are widely used in large mechanical equipment, metallurgy, railways, and chemical industries.

Application scenarios

1. Hydraulic system: Hydraulic system is one of the main application areas, which can control the flow rate of hydraulic system under different operating conditions, ensuring the stability and working efficiency of the system.

2. Heating system: It is also widely used in the heating industry, especially in air conditioning systems. It can ensure stable flow of hot water during the circulation process, thereby achieving constant temperature and energy savings.

3. Pneumatic system: Pneumatic system is also one of the application fields, which can control the flow rate of gas in different systems, ensuring the stability and efficiency of the system.
