Optimize as a supplement, described air outlet is connected with the vacuum blower vacuumizing, and described the first suction port is connected respectively the seal container that need to vacuumize with the second suction port, and the 3rd suction port is communicated with atmosphere.
The application process of four-way vacuum valve as above comprises the steps:
(1) when the seal container connecting when the first suction port need to vacuumize, the second cylinder advances and blocks the second suction port, motionless the 3rd suction port of blocking of the 3rd cylinder, the seal container that the vacuum blower that air outlet connects starts from the first gas flow path, the first suction port to be connected vacuumizes;
(2) when the seal container connecting when the second suction port need to vacuumize, the first cylinder advances and blocks the first suction port, motionless the 3rd suction port of blocking of the 3rd cylinder, the seal container that the vacuum blower that air outlet connects starts from the second gas flow path, the second suction port to be connected vacuumizes;
(3) when the seal container that the seal container connecting when the first suction port is connected with the second suction port does not need to vacuumize, the first cylinder and the second cylinder are blocked respectively the first suction port and the second suction port simultaneously, the 3rd cylinder declines and opens the 3rd suction port, internal cavities is communicated with atmosphere, and vacuum blower can be taken out atmosphere and work on; When the first suction port or the second suction port need to vacuumize, the 3rd cylinder rollback to initial position is blocked the 3rd suction port makes internal cavities airtight, repeating step (1) or step (2).
Model utility advantage:
Four-way vacuum valve described in the utility model can be continual alternately to two powder containers, carrying out vacuum takes out powder, make vacuum blower always in running order, not free wait, has improved upper powder efficiency greatly, upper powder per hour can reach more than 5 tons, is original twice.
