Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1：Referring to Fig. 1, Fig. 2, a kind of big flow automatic vacuum liquid-drainaged device, including vacuum tank 2, also include a control
Device processed and a liquid level sensor 7, described liquid level sensor 7 is located in vacuum tank 2, and described vacuum tank 2 side sets at bottom
There is leakage fluid dram, also include a threeway 4, described threeway 4 is made up of supervisor and arm, and described supervisor one end is connected by stop valve 3
Leakage fluid dram, the other end is connected to the pneumatic piston cylinder drawing water, described arm connected drainage water pipe 6；And set on discharge opeing water pipe 6
There is a liquid can only flow to the check valve 5 of discharge opeing water pipe 6 from threeway 4；
Described liquid level sensor 7 is connected with the input of controller, the output end phase of piston cylinder, stop valve 3 and controller
Even, its work is controlled by controller.
In the present embodiment, Master cylinder body 8 that described pneumatic piston cylinder includes being vertically arranged, first piston 9, wear from top to bottom
Enter the piston rod 10 that Master cylinder body 8 is connected with first piston 9, piston rod 10 top is provided with second piston 11, and cylinder body top is prolonged upwards
Stretch formation one subsidiary cylinder 12, described second piston 11 and subsidiary cylinder 12 be slidably matched, subsidiary cylinder 12 open top and with threeway 4
Supervisor connects, and described first piston 9 is provided with magnet ring, described vacuum tank 2 is additionally provided with sewage draining exit, subsidiary cylinder 12 top here
Liquid in-out mouth shown in opening i.e. Fig. 2.
Preparation before utility model works is：
1st, check whether source of the gas, power supply supply are normal；
2nd, adjustment completes positioning and the program correctness of initial position；
3rd, each motive position is adjusted to original state.
Operation principle of the present utility model is：
Vacuum tank 2, when vacuumizing state, can produce big quantity of fluid in tank body, during ambient systems are run, when in vacuum tank 2
Liquid capacity reach minimum liquid level and above when, liquid level sensor 7 feeds back signal to controller, and controller retransmits signal command
