AI Technical Summary
After the existing ash-removing valve is used for a period of time, smoke and dust ash is prone to accumulate at the valve, which changes the balanced weight of the valve, resulting in the failure of the sealing state and requires periodic cleaning. The use cost of the electric device is high and it is prone to accumulate smoke and dust ash and stuck in the motor, resulting in a risk of shutdown.
A gravity self-export trial ash removal valve is designed to automatically unload ash by gravity of the flip plate, and manually clean it using the rapid cleaning components, avoiding the use of electric devices.
It realizes automatic dust removal without electric devices, reduces usage costs and reduces failure rates, and only requires manual regular dust removal.

Technical Field
[0001] The utility model belongs to the technical field of ash discharge valves, in particular to a gravity self-unloading trial ash discharge valve. Background Art
[0002] The ash discharge valve is used for intermittent ash discharge in the sealed bin. Only when a certain amount of smoke and dust accumulates in the ash discharge valve will the valve be opened instantly to discharge the ash. In the rest of the time, the valve is closed and the outside air cannot enter the bin. After the existing ash discharge valve has been used for a period of time, smoke and dust are easily accumulated on the valve when it meets water. The accumulated dust changes the balance weight of the valve, and the valve cannot be kept in a normally closed and sealed state. The smoke and dust on the valve must be cleaned periodically to keep the valve plate clean and free of dust. The existing ash discharge valve is usually equipped with a complete set of electric devices to clean the accumulated dust, which makes its production and use cost relatively high, and it is easy for smoke and dust to accumulate and jam the motor during use, resulting in the risk of downtime.
