The course of work of the invention is specific as follows:
As shown in figure 4, the first electromagnetism guiding pneumatic operated valve 6 is to open (such as Fig. 5), and the second electromagnetism is oriented to pneumatic operated valve 19 when clingfish
To close (such as Fig. 6), four-way reversing valve 4 switches in negative pressure state.Pumping fish tube 1 is put into fish and water mixture, vacuum pump 3 is started,
Preceding port 10, the second electromagnetism for the second electromagnetism guiding pneumatic operated valve 19 being successively connected to through four-way reversing valve 4 are oriented to pneumatic operated valve 19
The rear port 12 for the first electromagnetism guiding pneumatic operated valve 6 that port 12 is connected to afterwards, the preceding port 10 of the first electromagnetism guiding pneumatic operated valve 6 are connected to
Fish tank 5 so that foring vacuum at once in fish tank 5；Fish and water is sucked with pumping fish tube 1 into fish tank 5, meanwhile, it is true in fish tank 5
Empty that voluntarily the valve plug of the valve plug connecting rod 7 of the second electromagnetism guiding pneumatic operated valve 19 is tightly sucked, valve port voluntarily has sealing state.
When the fish and water liquid level in fish tank 5 rises to the first liquid level meter 15, the first liquid level meter 15 issues signal instruction four-way
The preceding magnetic means 8 and rear magnetic means 14 of reversal valve 4 and the second electromagnetism guiding pneumatic operated valve 19 act；Second electromagnetism guiding is pneumatic
The preceding magnetic means 8 of valve 19 generates magnetic force and magnet piston 11 is released, and the piston area of magnet piston 11 is 21 side wall of cylinder block
The inner end of preceding waist hole 9 is blocked, the mobile B in 7 stroke of valve plug connecting rod of magnet piston 11, at this moment, the preceding waist hole 9 of 21 end of cylinder block
It is opened, air-flow enters the end of cylinder block 21,11 valve plug connecting rod 7 of magnet piston is sent to together at rear waist hole 13, rear magnetic force
The cathode of device 14 generates magnetic force and magnet piston 11 is sucked, and four-way reversing valve 4 switches, and negative pressure becomes positive pressure in fish tank 5, and vacuum is inhaled
Fish pump will enter live fish and discharge program.
As shown in fig. 7, form positive pressure when row fish in fish tank 5 and the fish and water in pumping fish tube 1 is forced to flow back, fish and water reflux liquid level
When being down to the second liquid level meter 2, the rear magnetic means 14 that the second liquid level meter 2 issues the first electromagnetism of signal instruction guiding pneumatic operated valve 6 is produced
Magnetisation power releases magnet piston 11, and the piston area of magnet piston 11 blocks up the inner end of the rear waist hole 13 on 21 side wall of cylinder block
Firmly, the mobile B in 7 stroke of valve plug connecting rod of magnet piston 11, at this moment, the rear waist hole 13 of 21 end of cylinder block is opened, air-flow into
The end for entering cylinder block 21, before 11 valve plug connecting rod 7 of magnet piston is sent to together at waist hole 9, the first electromagnetism is oriented to pneumatic operated valve 6 and closes
(such as Fig. 6) is closed, at this moment the fish and water at the first electromagnetism guiding 6 valve port of pneumatic operated valve drains, and it is existing that card fish will not occur when closing valve
As positive pressure in fish tank 5, the first electromagnetism guiding 6 valve plug of pneumatic operated valve is pushed down by pressure, 5 self-sealing of fish tank, work of the fish and water in pressure
Under, live fish is sent to the collection of live fish by defeated fish pipe 20.
As shown in figure 8, third liquid level meter 16 issues signal when fish and water liquid level drops to third liquid level meter 16 in fish tank 5
Instruct four-way reversing valve 4, the rear magnetic means 14 of the second electromagnetism guiding pneumatic operated valve 19 and preceding magnetic means 8 and the first electromagnetism guiding
The preceding magnetic means 8 and rear magnetic means 14 of pneumatic operated valve 6 act；Four-way reversing valve 4 switches, positive buckling negative pressure in fish tank 5, and second
The rear magnetic means 14 of electromagnetism guiding pneumatic operated valve 19 generates magnetic force and magnet piston 11 is released, and the piston area of magnet piston 11 is gas
The inner end of rear waist hole 13 on 21 side wall of cylinder body is blocked, the mobile B in 7 stroke of valve plug connecting rod of magnet piston 11, at this moment, cylinder block
The rear waist hole 13 of 21 ends is opened, and air-flow enters the end of cylinder block 21, before 11 valve plug connecting rod 7 of magnet piston is sent to together
At waist hole 9, preceding magnetic means 8 generates magnetic force and magnet piston 11 is sucked, and the second electromagnetism guiding pneumatic operated valve 19 executes closing, at this moment
Fish and water drains at valve port, and card fish phenomenon will not occur for valve closing；And the preceding magnetic means 8 of the first electromagnetism guiding pneumatic operated valve 6 produces
Magnetisation power releases magnet piston 11, and the piston area of magnet piston 11 blocks the inner end of the preceding waist hole 9 on 21 side wall of cylinder block,
The mobile B in 7 stroke of valve plug connecting rod of magnet piston 11, at this moment, the preceding waist hole 9 of 21 end of cylinder block is opened, and air-flow enters gas
The end of cylinder body 21 is together sent to 11 valve plug connecting rod 7 of magnet piston at rear waist hole 13, and rear magnetic means 14 generates magnetic force magnetic
Iron piston 11 is sucked, and (such as Fig. 5) is opened in the guiding execution of pneumatic operated valve 6 of the first electromagnetism；At this moment, vacuum is formed in fish tank 5 again, fishpump is again
Original clingfish state is returned to, is thusly-formed circulation suction, row fish touches formula.
A kind of heretofore described vacuum fishpump bubbled through the water column, fish tank are bubbled through the water column, and are oriented to using electromagnetism pneumatic
Valve meets liquid level meter and directly controls, and is turned on the power using the strength that vacuum fishpump has itself as valve member, and four-way commutates
The switching of valve, air-flow can be directly entered in fish tank, solved valve member and opened the time difference generated with airflow；The fishpump, energy
Live fish quality is effectively improved, energy consumption is reduced, has filled up the blank that vacuum fishpump is conveyed toward eminence.
