The hydraulic butterfly valve is a kind of multi-purpose valve with high flow control accuracy and wide application range. According to different structures and control methods, hydraulic butterfly valves can be divided into a variety of types, the following will introduce its main types and their application scenarios.
1. Double acting hydraulic butterfly valve
Double acting hydraulic butterfly valve is a valve controlled by two hydraulic pressure control units. It has the advantages of fast response, high precision, simple operation, etc., and is widely used in chemical industry, hydraulic system and other fields. This valve has a shorter closing delay time, which is suitable for use under working conditions requiring high flow, high sensitivity and high speed, and is applied to pneumatic and hydraulic automatic control systems.
2. Electric hydraulic control butterfly valve
The electro-hydraulic butterfly valve is a variant of the hydraulic butterfly valve, and its structure is similar to that of the hydraulic butterfly valve. The actuator part is equipped with the electro-hydraulic commutator and feedback sensor, and the opening of the valve is controlled by the circuit, which has higher operating accuracy and stability. Because the electric hydraulic commutator is used instead of the original hydraulic commutator, the control part and the executive part can be separated, so as to realize human-computer interaction and automatic control.
3. Simulated electric hydraulic control butterfly valve
The analogue electrohydraulic control butterfly valve is a kind of hydraulic control butterfly valve that can control the opening of the valve by controlling the electrical signal. It can control the opening by simulating the size of the voltage or current, and can even be closed-loop control. Suitable for applications requiring fine adjustment and frequent change of opening, such as water treatment, petrochemical and other industries.
4. Electromechanical hydraulic butterfly valve
Electromechanical hydraulic control butterfly valve is a combination of mechanical, electrical and hydraulic control of a variety of control valves, through electrical signals and hydraulic signals to achieve fine flow regulation control. Suitable for applications where multiple parameters need to be controlled at the same time, such as sewage treatment, environmental protection industry, etc.
5. Digital hydraulic butterfly valve
Digital hydraulic butterfly valve is a combination of digital circuit and hydraulic control technology, through high-speed computer control to achieve flow control valve. It has the advantages of high precision, fast response speed, strong programmability, etc., and is suitable for occasions requiring high-precision flow regulation and frequent change of control signals, such as aerospace and other fields.
In short, when selecting the hydraulic butterfly valve, it is necessary to select the appropriate type according to the actual application scenario and combined with the characteristics and functions of the hydraulic butterfly valve, improve the flow adjustment accuracy and control efficiency, and achieve better product working results.
