Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valve discharging, in particular to a flap type valve. Background Art
[0002] Flap valves are often used to control fluid discharge, and flap valves are used to facilitate collection and processing. At the same time, during the unloading process, when the valve is closed, it can not only cut off the material, but also play a role in isolating and locking the air.
[0003] When using a flap valve to control the outflow of cement powder, due to its fine particles and high adhesion, the cement powder is easy to accumulate inside the valve and adhere to the valve plate or valve seat. As time goes by, these accumulations may gradually increase, causing the cement powder to easily clog the inner wall after the valve is opened and difficult to fall. At this time, a flap valve that is not easy to clog is needed. Utility Model Content
