1、 Purpose:
SK dual channel conveying valves are commonly used in industries such as building materials, metallurgy, mining, petrochemicals, electricity, and light industry. They are used in pipeline systems for high-pressure pneumatic conveying of powdery substances such as cement, cement raw materials, limestone, coal powder, etc. They play a role in conveying direction and are generally installed at the branching points of pipelines.
Structural Features
The internal reversing of SK dual channel conveying valve adopts a rotating valve disc, which is controlled by a pressure regulating device to match the sealing surface. The valve disc adopts a blade shape to cut off the attachments on the sealing surface during movement and ensure sealing performance. The structure of Nantong Zhongkuang's dual channel conveying valve is complete, with flexible and reliable direction change, good air tightness, wear resistance, etc. The conveying channel is smooth and unobstructed, ensuring smooth fluid flow. S is a worm gear transmission type, D is an electric transmission type, and Y is an electro-hydraulic transmission type.
3、 Working principle
The SK dual channel conveying valve is mainly composed of left and right valve bodies, rotating valve discs, regulating devices, sealing surfaces, and positioning cams. Manually operate the handwheel to drive the worm gear and drive the operating rod, and the valve disc moves together. The valve body is in the straight or branch position, and the dial feedbacks the position of the valve disc; When the driving device receives the command action, it drives the control rod and the valve disc to move together, making the valve body in the straight or branch position, and feedback the position signal. When the positioning cam mechanism reaches the valve disc, it will activate the electrical switch and feedback the signal.
