Positive Pressure Delivery Rotary Valve

Equipped with equalizing port, it can effectively convey materials under positive pressure. The number and thickness of blades will increase to effectively prevent backflow.

Positive pressure conveying rotary valve is a material conveying equipment specially designed for positive pressure conditions in pneumatic conveying system, and is widely used in grain, chemical, building materials, electricity, metallurgy, environmental protection and other industries. The rotary valve can operate stably in a closed pipeline, equipped with equalizing port structure and thickened and dense rotor blade design, ensuring stable feeding, sealing and locking air, and preventing backflow under high pressure environment. It is an important component for building an efficient pneumatic conveying system.

The equalizing port can effectively balance the pressure difference between the rotary cavity and the downstream pipeline, prevent the rotary valve from generating "air lock" due to uneven internal and external pressure, and ensure continuous and stable material feeding without blockage or impact.

Thickening and dense design of rotor blades
·Increasing the number of blades, effectively reducing the volume of each grid, and increasing the feeding density;
·Thickening the blades improves their rigidity and wear resistance, and maintains structural stability under positive pressure gas impact;
·Tight blade gap and rotor structure can effectively prevent backflow and material backspray.

Strengthened sealing structure
·Through multiple sealing designs (such as labyrinth seals, graphite seals, packing seals, etc.), materials are still prevented from leaking and gas from backflowing under positive pressure, ensuring the sealing and conveying efficiency of the entire pneumatic system.
·The stable pressure-resistant structure is particularly suitable for 0.1~0.6Mpa positive pressure pneumatic systems
