Each regulating valve is customized for users.

This series of regulating valves. Adopting a labyrinth flow channel and multi-stage valve core design, the structure is compact and can work stably under high temperature and high pressure difference conditions. Equipped with our company's designed intelligent actuator, the positive and negative action modes can be freely replaced on site. And it can provide effective anti-corrosion protection for the spring, thereby extending the service life of the actuator. The actuator and intelligent valve positioner are connected without pipelines, which improves the seismic performance, stability, and adjustment accuracy of the regulating valve. The double-sided valve seat and body compression connection method effectively improves the sealing level and service life of the valve, making maintenance and repair extremely convenient, thereby greatly enhancing the comprehensive performance of the regulating valve. By replacing the valve cover structure, it can be applied to various high-temperature and zero leakage situations, meeting different user requirements.

Pneumatic YSIQ70:

The locator receives standard current signals or computer signals, converts them into valve position set values, and converts the linear displacement of the actuator into angular displacement through a connecting device, which is measured by a position sensor and fed back to the microprocessor.

The microprocessor compares the actual valve position feedback value with the set value, detects the deviation, and outputs a pulse width modulation command (PWM) to the piezoelectric valve based on the magnitude and direction of the deviation. The piezoelectric valve adjusts the intake or exhaust volume of the diaphragm head according to the control command.

Electric YSID70:

After A/D conversion, the standard current signal or computer signal enters the intelligent signal acquisition and control unit of the intelligent electric actuator.

The signal acquisition control unit constantly detects the input signal and position feedback signal. When the two signals are unbalanced, it outputs a pulse width modulation command (PWM) to the bidirectional thyristor based on the magnitude and direction of the deviation, making it conductive and driving the motor to operate in the direction of reducing the deviation, thereby driving the deceleration mechanism and changing the opening of the valve.

control model

The control mode adopts PWM (Puise Width Modulation) drive;

Full speed state: When the control deviation is large, output a continuous signal;

Medium speed state: When the deviation is not significant, output a pulse signal;

Slow fine-tuning: When the deviation is small, output a smaller pulse signal;

Maintain positioning: When the deviation is small enough within the range of valve adjustment accuracy, there is no control command output.

The hedge ring labyrinth structure is designed based on the porous anti cavitation sleeve valve and multi-stage throttling principle, and is a new product of high-pressure differential anti cavitation regulating valve. The maze structure is composed of multiple opposing ring disks stacked together, using special structures and techniques. Compared with traditional maze structures, it has better processability and better pressure reduction and noise reduction effects. Due to the use of the hedging principle, when the medium passes through the ring groove on the disc, it will generate impact, friction, and vortex, thereby consuming a large amount of energy, which can effectively reduce the pressure. Under the same working conditions, fewer pressure reduction stages can be used to meet the usage requirements.
