In choosing a small rotary valve, besides considering the material discharge rate per revolution and the operating speed, we should also consider the size of the inlet port of the rotary valve that we will be using. Each material has different channel capacity properties. small rotary valve The small inlet port prevents some materials from flowing into the valve housing and thus can clog the valve face.
This can be determined by selecting either hand that can be extended with the thumb parallel to the axis of the screw conveyer. And can hold all four fingers around the axis of the screw conveyer In the same direction as the flight around the axis of the screw conveyer. If it's the left hand, it's called the left hand, or if it's the right hand,
The construction of a screw conveyor using the blade pitch at the entrance short pitch than the general pitch (conveying pitch) is another way to prevent knocking of the screw conveyors. Due to the compression of the material during the conveying after the material compresses at the inlet, when it reaches the conveying range, the pitch is wider. The material will break down, not compact, making it easy to flow. To calculate the loading rate of this type of screw conveyor, the inlet pitch is used to calculate, in other words, the inlet conveyor screw blade pitch determines the material handling rate.
Our rotary valve standard model has a size DN100 to DN600. We can overhaul and produce with other size.
