Introduction to double-layer electric air-locking flap valve Huaying Environmental Protection Factory Direct Sales

Product introduction editor
Double-layer electric air-locking flap valve
Also known as air-locking feeder, it has two categories: single door and double door. It is widely used in building materials, metallurgy, chemical industry, In industries such as electric power, it is used as the ash hopper unloading device of various dust removal equipment and the feeding and unloading device of various grinding machines, dryers, silos and other equipment to prevent wild wind from blowing in.
This series of valves adopts a steel plate welded structure, connecting rod, crank transmission mechanism, and automatic reset mechanism. It has a compact structure and works smoothly and reliably.
Working principle editor
The reducer drives the transmission rod through the crank, cam and connecting rod to drive the upper and lower transmission shafts to rotate and open interactively. Through the equipped lever system or tension spring, the valve plate is ensured Reliable reset to prevent wild wind from blowing in, and complete the feeding and unloading of the system according to the determined opening and closing frequency.
Structural Features Editor
Double-layer electric air-locking flap valve plate
It has two sealing surfaces. The two sealing surfaces of the most commonly used model gate valve form a wedge shape. The wedge angle changes with the valve parameters. Different, usually, the gate of the wedge gate valve can be made into a whole, called a rigid gate, or it can be made into a gate that can produce slight deformation to improve its craftsmanship and compensate for the angle of the sealing surface during the processing. The deviation caused by this kind of gate is called an elastic gate. When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, relying on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing surface. The seal is that the self-sealing part of the gate valve adopts forced sealing, that is, when the valve is closed, external force must be relied on to force the gate to the valve seat to ensure the sealing performance of the sealing surface
