The working principle of the invention:
The working principle of the coal-grinding distributing valve is mainly sketched as following four situation:
Situation one (upper slide valve moves to left end, and lower slide valve moves to right end)
Since lower slide valve moves to right end, so left channel of the coal dust in direction controlling block is in the open state, with upper slide valve
Access between be connected directly；Again since upper slide valve moves to left end, reduce with lower slide valve associated channel area of section, pulverized coal flow
Reduce, and flowed out by a mouthfuls, enters back into b mouthfuls, flowed directly out via the left side discharge port being connected with lower slide valve.
Situation two (upper and lower slide valve moves to left end)
Left end is moved to by lower slide valve, so left channel of the coal dust in direction controlling block is in close state；Again due to upper
Slide valve also moves to left end, so right channel of the coal dust in direction controlling block is also at closed state, then the coal-grinding divides at this time
Not flow regime is in the coal dust in valve.
Situation three (upper and lower slide valve moves to right end)
Since upper and lower slide valve moves to right end, so right side feed passageway of the coal dust in direction controlling block is in the open state,
It is connected directly between the access of upper slide valve, reduces with lower slide valve associated channel area of section, pulverized coal flow reduces, and coal dust can be straight
It connects and is flowed out by b mouthfuls, enter back into a mouthfuls, flowed directly out via the right side discharge port being connected with lower slide valve.
Situation four (upper slide valve moves to right end, and lower slide valve moves to left end)
It is and upper so right side feed passageway of the coal dust in direction controlling block is in the open state since lower slide valve moves to left end
Be connected directly between the access of slide valve, lower slide valve moves to left end, at this time maximum flow of the coal dust in aspect control block, coal dust via
B mouthfuls of outflows, enter back into a mouthfuls, and flow directly out from the right side discharge port being connected with lower slide valve.
In conclusion the coal-grinding distributing valve passes through moving left and right for control or more slide valve, and then coal dust is controlled in valve body
Flow direction and flow.
