Intelligent switch type adjustment type, intelligent electric flange ball valve

The electric flange ball valve adopts an integrated structure, and has an input control signal (4~20mA DC or 1-5V DC) and a single-phase power supply to control the operation. It has strong function, small size, light and cheap, reliable performance and simple matching. Flow capacity, especially suitable for occasions where the medium is viscous, containing particles, and fiber properties. At present, the valve is widely used in industrial automatic control systems for food, environmental protection, light industry, petroleum, paper, chemical teaching and research equipment, electric power and other industries.

working principle:

The electric flange ball valve is suitable for two-way cutting and adjustment. The connection between the electric flange ball valve and the actuator is directly connected. The electric actuator has a built-in servo system. It does not need to be equipped with a servo amplifier. It can be controlled by inputting 4-20mA signal and 220VAC power supply. The utility model has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable operation and the like. The actuator can also be equipped with electronic electric actuators such as UNIC, PSQ, HQ, DHL, etc. or gas piston actuators such as GTX and AL according to user requirements.

The electric actuator can directly receive the 4~20mADC or 1~5VDC control signal output from the computer or industrial instrument, 220VAC power supply, and intelligent step adjustment of the actuator drive motor according to the deviation of the valve position feedback signal and the set value (PID adjustment) ), to achieve precise positioning of the valve or other device opening with the actuator, and output the position feedback signal of 4 ~ 20mADC. Its core control component electronic servo controller is designed with modern digital technology and designed for DCS/PLC specification. It integrates signal acquisition, processing, feedback and control. The original electronic brake circuit is added and the mechanical damping device is added to eliminate the inertia, which can be stopped instantaneously, without oscillation during positioning, and the positioning accuracy can reach 0.3% or more. SCR output, fast action time, stable output and high reliability. Small size, light and cheap, reliable performance, simple matching, large circulation capacity, especially suitable for occasions where the medium is viscous, containing particles and fiber properties. At present, the valve is widely used in industrial control factors of food, environmental protection, light industry, petroleum, paper, chemical, teaching and research equipment, power and other industries.

Features:

1. The electric ball valve has small fluid resistance and is a small type of fluid resistance in all valves. It is powered by AC220V, AC380V or DC24V power supply voltage and accepts (4-20mA, 0-10mA or 1-5VDC) current signal or voltage. The signal can be controlled to operate, and the torque of the angular output can be rotated from 0 to 90o to complete the opening and closing action or the adjustment action.

2. The core channel is smooth and smooth, it is not easy to deposit medium, and it can be used for pipeline type. The structure is simple, the weight is light, and the sealing performance is good. Especially suitable for applications requiring zero leakage rate.

3, using HL type, 3810R type, PSQ type angular stroke full electronic electric actuator is the O-type ball valve drive device, mechanical and electrical integration structure design, with internal servo operation and opening signal position feedback, position indication, manual Operation and other functions, strong function, reliable performance, simple connection, AC220V or AC380V power supply voltage, directly accept the unified standard signal (4-20mA DC, 0-10mA DC or 1-5V DC, 0-10V DC),

This is converted into a displacement corresponding to the input signal, and is moved by an angular displacement (0 to 90o) to change the rotational opening of the core. Therefore, a certain input signal corresponds to a certain position opening degree, and a proportional adjustment action is realized. (The two-position switch adopts AC220V or AC380V power supply voltage as power, realizes the switching action through the positive and negative motor rotation, and simultaneously outputs the switch valve position indication signal). It is a high precision, high performance, high reliability product.
