What is electric regulating valve?
Electric regulating valve is an important execution unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being used more and more in various industrial production fields. Compared with the traditional pneumatic control valve, it has obvious advantages: the electric Regulating valve is energy-saving (only consumes electricity when working), environmentally friendly (no carbon emission), and quick and convenient installation (no complicated pneumatic pipelines and air pump workstations are required).
Valve structure of electric actuator valve
The electric control valve,electric water valve is composed of the electric actuator and the regulating valve after being connected and combined by mechanical connection, assembly, debugging and installation.
Working principle of electrical actuators
Working power supply: DC24V, AC220V, AC380V AC110V,DC12V, and other voltage levels.
Input control signal: DC4-20MA or DC1-5V, 0-10V,0-5V
Feedback control signal: DC4-20MA (load resistance below 500 ohms)
By receiving the signal of the industrial automation control system (such as: 4~20mA), the valve is driven to change the cross-sectional area between the valve core and the valve seat to control the flow, temperature, pressure and other process parameters of the pipeline medium. Realize automatic adjustment function.
The new type of electric control valve actuator contains feeding function, which accepts a unified standard signal of 4-20mA or 1-5V·DC, converts the current signal into a corresponding linear displacement, and automatically controls the opening of the control valve, so as to meet the requirements of the pipeline. Continuous adjustment of process parameters such as pressure, flow, temperature and liquid level of the internal fluid.
Flow characteristics
The flow characteristic of the electric control valve,electric actuator valve is the relationship between the relative flow of the medium flowing through the electric control valve and its opening under the condition that the pressure difference between the two ends of the valve remains constant.
The flow characteristics of the electric regulating valve are: linear characteristics, equal percentage characteristics and parabolic characteristics.
Application field
Electric power, chemical industry, metallurgy, environmental protection, water treatment, light industry, building materials and other industrial automation systems.
Install of actuators electric
The electric regulating valve is most suitable to be installed with the upper end of the working piston at the lower part of the horizontal pipeline. The temperature sensor can be installed in any position and the entire length must be immersed in the controlled medium.
Electric control valves generally include a driver, which accepts driver signals (0-10V or 4-20MA) to control the valve for adjustment, and can also form an intelligent network control system according to control needs to optimize control to achieve remote monitoring.
Electrical Principles
Action principle: motor power supply 220VAC or 110VAC, control signal 4~20mA, there is a controller in the valve, the controller converts the current signal into the angular stroke signal of the stepper motor, the motor rotates, driven by gears, levers, or gears and levers Stem operation for straight or angular travel
Feedback: The motor runs through the gear, and the three-joint sliding rheostat outputs the valve's positioning signal, in addition to the three-line limit signal (fully open, fully closed. Common line).
The intelligent electric regulating valve is a pressure balance regulating valve.
The overall structure is compact, light in weight, good in stability and high in protection level. Therefore, it is widely used in automatic adjustment systems such as large thermal power plants, chemical plants, water treatment and sewage treatment, natural gas oil fields, and steel plants.
What is difference between on-off electric valve and regulating electric valve?
Electric valve overview:
Electric valve is a common valve controlled by power supply, w.hich is mainly used in pipeline systems of various industries to control the switching and adjustment of media. The emergence and use of electric valves also perfectly reflects valve intelligent technology change. And it can fully meet the standardization requirements in the test, so the electric valve has also become an intelligent control valve favored by users among the valve types.
The difference between on-off electric valve and regulating electric valve:
The difference between the switch-type electric valve and the regulating type electric valve is that the switch-type electric valve is only used as a switch for the quality of the main pipeline, usually fully open or fully closed. The adjustable electric dampening door is not
It can only use dry switch and also can use dry adjustment (4~20mA or 0-10V) signal input and output. Therefore, when selecting models, we must pay attention to whether the on-site use requirements are switch-type or adjustment-type.
On-off electric valve:
The function of the on and off-type electric valve on the pipeline is mainly to fully open or fully close, usually refers to the electric gate valve,electric ball valve,electric actuated butterfly valve, the electric globe valve, and the electric gate valve and the electric globe valve are classified into a straight stroke, because the electric gate valve and
The electric globe valve is a dry up and down forced sealing structure. The working principle is also based on the power supply (AC220V or AC110V), and this conversion is driven by the straight-stroke electric actuator to move the valve stem up and down.
