Abstract

The invention discloses a timing controlled intermittent fluid controller. The timing controlled intermittent fluid controller comprises an STC89C52RC single-chip microcomputer, a keystroke input device, a storage chip, a clock chip, a relay and a liquid crystal display device. The keystroke input device, the storage chip, the clock chip, the relay and the liquid crystal display device are all connected with the STC89C52RC single-chip microcomputer and controlled by the STC89C52RC single-chip microcomputer. The timing controlled intermittent fluid controller controls an electromagnetic valve to turn on and turn off through the relay by setting the parameters such as the running time, the turn-on time and the turn-off time to implement control over the intermittent frequency and the interval time of liquid fluid in a pipeline, is accurate in control and convenient to operate and achieves the effect of human-computer interaction.

Description

technical field [0001] The invention relates to a timing-controllable intermittent fluid controller and a method for adjusting fluid intermittent frequency, belonging to the technical field of fluid timing control. Background technique [0002] The fluid controller can control the fluid flow state, and has the functions of adjustment, diversion, retention and so on. [0003] The patent application with the publication number CN106164549A discloses a fluid controller, which adjusts the flow rate by limiting the up and down movement of the valve stem accompanying the opening and closing. This method suppresses an increase in cost due to addition of components for the setting unit, etc., but the control is inflexible and timing control cannot be performed. [0004] The application with the publication number CN106471300A discloses a fluid controller, which is a fluid controller that adjusts the flow rate by limiting the up and down movement of the valve stem (stem) accompanyin...
