Description

Improved structure of flap valve

Technical Field

The utility model relates to a flap valve technical field, concretely relates to flap valve improves structure.

Background

The flap valve is used as an ash bucket unloading device of various removing devices and a feeding and unloading device of various mills, dryers, storage bins and other devices, prevents wild wind from blowing in, and takes a heavy hammer, an electric motor and a push rod as main driving forces; the valve plate of plate valve is opened automatically under the action of material gravity, and after the material fell, counter weight lever system made the valve plate automatic re-setting, prevented that open air from blowing in to accomplish the transport of material. The double-layer flap valve mainly utilizes the switches of the upper valve and the lower valve at different time to ensure that a layer of valve plate is always in a closed and isolated state in the middle of the equipment so as to prevent air channeling. If the pneumatic double-layer air locking valve is used for positive pressure conveying, the pneumatic double-layer air locking valve can also play a role in balancing and flow aiding of the pressurizing valve, so that the continuous pulsating feeding of the equipment can be realized, and meanwhile, the air locking function is realized, and the requirement of pneumatic conveying of powder and granular materials is met.

The valve port of the existing flap valve needs to be opened and closed manually to complete the operation, and the working efficiency is low, so that further improvement treatment is needed.
