Abstract

The invention discloses a precision device for controlling the flow rate of liquid. The precision device comprises a first liquid driving assembly and a second liquid driving assembly. The first liquid driving assembly comprises a first driving component and a rotary type central shaft. The first driving component drives the rotary type central shaft to rotate. The side face of the rotary type central shaft is provided with a first central hole and a second central hole. The second liquid driving assembly comprises a second driving component, a piston head, a liquid storage cavity and a cavityouter shell. The second driving component drives the piston head to move in the liquid storage cavity. The liquid storage cavity is fixedly formed in the cavity outer shell. The cavity outer shell isprovided with a first through hole and a second through hole. The first through hole is formed between the liquid storage cavity and the first central hole. The second through hole is formed betweenthe liquid storage cavity and the second central hole. The invention further discloses an application method of the precision device for controlling the flow rate of the liquid. The needed quantitative liquid is precisely conveyed through the double liquid driving assemblies; and meanwhile, the precision device is compact in structure and wide in application scope.

Description

technical field [0001] The invention relates to the technical field of liquid conveying equipment, in particular to a precision device for controlling liquid flow and its application method. Background technique [0002] At present, the entry and exit of liquid on the market is realized by a solenoid valve. The movement of the cylinder is driven by the solenoid valve to drive the center rod to move, and the reciprocating motion of the drive center rod is used to control the liquid in and out during the transmission process, even Turning the device on and off. [0003] This traditional simple device structure often has the phenomenon of unstable liquid flow rate and uneven liquid delivery, and then the work of the overall equipment is intermittent, which seriously affects the production workflow. Contents of the invention [0004] An object of the present invention is to provide a precision device for controlling the flow of liquid. The liquid flow in and out can be precis...
