Pneumatic dispatching valve is one of the industrial process control instruments widely used in petroleum, chemical, electric power, metallurgy and other industrial enterprises. According to the operation principle of pneumatic dispatching valve, compressed air is used as the power source, air cylinder is used as the performance arrangement, electric valve positioner, converter, solenoid valve, positioning valve and other accessories are used to drive the valve, end the switching value or share dispatching, receive the control signal of industrial automatic control system, and end the dispatching of pipeline medium: flow, pressure, temperature and other process parameters. Pneumatic dispatching valve is characterized by simple control, fast response, intrinsically safe, no need to take explosion-proof method.
What are the characteristics and usefulness of pneumatic scheduling valves in the clarification of pneumatic scheduling valves?
The use and characteristics of pneumatic dispatching valve: it is a right-angle reverse layout, which can be used in conjunction with valve positioner to end share dispatching. V-shaped spool is most suitable for various dispatching occasions, with large rated flow coefficient, large adjustable ratio, good sealing performance, lively dispatching function, small volume and vertical installation. Suitable for controlling gas, steam, liquid and other media.
The characteristics of pneumatic dispatching valve are: it is a right-angle reverse layout, which is composed of V-shaped valve body, pneumatic actuator, positioner and other accessories. It has the inherent flow characteristics similar to that of 100 ratio. The double bearing layout is selected, with small initiating torque and excellent activity and induction speed. Super shearing ability.
The pneumatic piston performs the arrangement with compressed air as the power source, and the crank arm is rotated 90 degrees through the movement of the piston to make the valve active switch. Its components are: dispatching bolt, fulfilling arrangement box, crank arm, cylinder, cylinder shaft, piston, connecting rod, cardan shaft.
Working principle of pneumatic scheduling valve: Pneumatic scheduling valve consists of fulfillment arrangement and scheduling arrangement. The fulfillment arrangement is the thrust component of the dispatch valve, which generates the corresponding thrust according to the control signal pressure to advance the action of the dispatch arrangement. The valve body is a part of the pneumatic scheduling valve, which directly touches the scheduling medium and schedules the flow of fluid.
