Fig. 2 is a schematic view of the overall structure of the present invention.
Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.
In this embodiment, as shown in fig. 1 and 2, a flexible liquid filling control system includes four tank chambers, and the tank chambers are connected by a bottom manifold. Steel structure supports are arranged around the steel support. The liquid inlet end is provided with two electric valves which are arranged on a tank bottom manifold in parallel, the liquid outlet end is provided with two electric valves which are arranged on the tank bottom manifold in parallel, a liquid level meter (a pressure transmitter) is arranged on the liquid outlet end manifold, and a control box is arranged at the bottom of the water tank. The control cabinet is provided with a liquid level indicating instrument for displaying the current liquid level value, a liquid inlet end electric valve control knob for simultaneously opening/closing the two electric valves, and a liquid outlet end control knob for simultaneously opening/closing the two electric valves. A local/remote switching knob. The control cabinet, the electric valve and the liquid level meter are connected to a PLC in the control cabinet through hard wires, and the control cabinet can be communicated with an upper computer through Ethernet.
When the knob is switched to be remote, the upper computer system can automatically adjust according to the height of the liquid level in the tank, and when the liquid level reaches 95% of the height of the liquid tank, liquid supply at the liquid inlet end is automatically stopped. The tank provides drainage when the liquid level is below 5%. The liquid tank can simultaneously supply and discharge liquid when the liquid level is between 5 and 95 percent.
When the knob is switched to the local place, liquid can be fed and discharged according to the operation of actual working conditions. When the liquid level reaches 95% of the height of the liquid tank, the system can automatically stop liquid supply at the liquid inlet end.
