The utility model discloses a theory of operation:
the working principle of the coal grinding distribution valve is mainly briefly described as the following four conditions:
case one (Upper slide valve to left and lower slide valve to right)
The lower slide valve moves to the right end, so that a left passage of the pulverized coal in the direction control block is in an open state and is directly connected with a passage of the upper slide valve; and because the upper slide valve moves to the left end, the cross section area of a channel communicated with the lower slide valve is reduced, the flow of the pulverized coal is reduced, and the pulverized coal flows out from the port a, then enters the port b and directly flows out from a left discharge port connected with the lower slide valve.
Case two (Upper and lower slide valve moving to left)
The coal dust is moved to the left end from the lower slide valve, so that a left passage of the coal dust in the direction control block is in a closed state; and since the upper slide valve is also moved to the left end, the right passage of the pulverized coal in the direction control block is also in a closed state, and the pulverized coal in the pulverized coal distribution valve is in a non-flowing state at the moment.
Case three (Upper and lower slide valve moving to right end)
Because the upper slide valve and the lower slide valve are moved to the right end, a right feeding passage of the pulverized coal in the direction control block is in an open state and is directly connected with a passage of the upper slide valve, the cross section area of a passage communicated with the lower slide valve is reduced, the flow rate of the pulverized coal is reduced, and the pulverized coal can directly flow out from the port b, then enters the port a and directly flows out through a right discharge port connected with the lower slide valve.
Case four (Upper slide valve to right and lower slide valve to left)
The lower slide valve moves to the left end, so that a right feeding passage of the coal powder in the direction control block is in an open state and is directly connected with passages of the upper slide valve, the lower slide valve moves to the left end, the flow of the coal powder in the direction control block is maximum at the moment, and the coal powder flows out from the port b, then enters the port a and directly flows out from a right discharge port connected with the lower slide valve.
In summary, the coal grinding distribution valve controls the left and right movement of the upper and lower slide valves, so as to control the flow direction and flow rate of the pulverized coal in the valve body.
