Intelligent switch type external regulation electric flanged ball valve gate
Electric flanged ball valve door adopt integration structure with input control signals (
4 ~ 20 ma DC or 1 -
And single-phase power supply can control operation, with strong function, small size, light and pleasant, form a complete set of reliable performance, simple, flow capacity, especially suitable for medium is sticky, including particle and fiber properties.
At present, the valve is widely used in food, environmental protection, light industry, petroleum, paper making, chemical teaching and scientific research equipment, electric power industries such as industrial automatic control system.
Working principle: electric flanged ball valve door is suitable for the two cut off, adjust the occasion.
Electric flanged ball valve door USES the direct way to connect the valve and actuator, electric actuator, built-in servo system do not need to match servo amplifier, enter 4
20 ma signal and 220 vac power can control operation.
Attachment with simple, compact structure, small size, light weight, small resistance, the advantages of stable and reliable.
Actuator can according to user requirements, another configuration UNIC, PSQ, HQ, DHL and other types of electronic electric actuators or GTX, AL gas piston type actuators, etc.
Electric actuators can be directly receiving computer or industrial instruments such as the output of 4 ~ 20 madc or 1 ~ 5 VDC control signal, the 220 vac power, according to the valve position feedback signal is compared with the set value deviation interval adjustment to smart actuator drive motor (
To achieve and form a complete set of valve actuator precise positioning of the opening of the door or other devices, and output of 4 ~ 20 madc position feedback signal.
The core control components of electronic servo controller applying modern digital technology, designed for DCS/PLC specification, signal acquisition, processing, feedback and control in a body.
Use original electronic braking circuit and additional mechanical inertia, damping device to eliminate for instantaneous stop, no oscillation, when positioning precision can reach 0.
More than 3%.
Silicon controlled rectifier output, action time is fast, stable output, high reliability.
Small volume, light and pleasant, reliable performance, simple, large flow capacity, especially suitable for medium is sticky, including particle and fiber properties.
Now the valve is widely used in food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, electric power industries such as industrial control coefficient.
Product features: 1, the electric ball valve fluid resistance small, are all valves fluid resistance in the smallest one, with AC220V, AC380V or DC24V power supply voltage, accept (
10 ma or 1 -
Current or voltage signal, can control operation, to Angle the itinerary of the output torque rotating sphere 0 ~ 90 & ordm;
, can complete opening and closing action or adjust the action.
2, ball core channel level off is smooth, not easy to deposit medium, can be in-line ball.
Simple structure, light weight, good sealing performance.
Especially suitable for the requirement of zero leakage rate.
3, using the HL type, 3810 r, PSQ quarter-turn all electronic electric actuator gate of o-type ball valve actuating device, the structure of the electromechanical integration design, machine servo operation and opening position feedback signal, position indicator, manual operation, and other functions, functional, reliable performance, simple wiring, with AC220V or AC380V voltage power, directly to a unified standard signal (
10 ma DC or 1 -
0 - 5 v直流
And turn it into corresponding to the input signal displacement, Angle displacement (
Movement, change the rotation of the ball core opening, so a certain position of the input signal corresponding to a certain opening, realize the proportional control action.
Two switch type accept AC220V or AC380V voltage power, through the motor and reversing switch action, and at the same time the output switch valve indicator)
Is a kind of high precision, high performance, high reliability products.
