Pouring material flap valve

The working principle of the pouring material flap valve mainly relies on pneumatic or electric operation, and the valve is opened and closed by controlling the movement of the valve stem. Specifically, when the air source is introduced from the upper intake port, the valve stem drives the valve plate to move downward and the valve closes; When the gas source is introduced from the lower air inlet, the valve stem drives the valve plate to move upward and the valve opens. The spring loaded between the valve plate and the valve seat always presses the valve plate into the valve seat, protecting the sealing performance of the valve, while allowing the valve plate to move vertically up and down, helping to compensate for the thermal expansion and contraction of valve parts, overcoming the impact of any back pressure changes on the seal, and preventing particulate media from entering between the two sealing surfaces. In addition, the valve plate can rotate during the opening and closing process, causing grinding and polishing between the sealing surfaces. Moreover, due to the eccentricity of the valve body towards the channel, eddy currents are generated during the opening and unloading of materials. The material eddy currents formed will clean the valve cavity on their own, protecting the valve cavity from dust accumulation. This feature ensures that the pouring material flap valve has a long service life and excellent sealing performance.

The design of the new pouring material flap valve also includes adding maintenance doors, pulse holes, etc. These improvements have improved the opening and closing performance of the flap valve, facilitated the maintenance and disassembly of the valve plate, and greatly reduced the workload of maintenance personnel. At the same time, the high-temperature strength of the flap valve is improved by using the lining material of the casting material and adopting slow baking and high-temperature firing methods, which increases the service life by 2-3 times. This improvement not only enhances the overall performance of the flap valve, but also achieves significant benefits in industrial processes such as cement production.
