Fig. 1 is a schematic structural diagram of an electrolyte solution feeding system with an emergency shutdown function according to the present invention.

Detailed Description

The electrolyte solution feeding system with emergency shutdown function of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

Please refer to fig. 1.

The utility model provides an electrolyte transfusion system with emergency shutdown function, mainly used electrolyte transmission and partial shipment, electrolyte transfusion system mainly includes infusion pipeline 100, first control valve 200, second control valve 300, pressure sensor 400 and controller 500.

The infusion pipeline 100 is provided with a feeding end 110 and a plurality of discharging ends 120 communicated with the feeding end 110, wherein the feeding end 110 is used for feeding electrolyte raw materials, specifically, the feeding end 110 is connected with a container for containing the electrolyte raw materials, the discharging ends 120 are respectively used for being connected with liquid injection barrels for subpackaging, and in the electrolyte conveying process, electrolyte enters the infusion pipeline 100 from the feeding end 110 and then is input into different liquid injection barrels through the discharging ends 120.

The first control valve 200 is disposed at the feeding end, the second control valve 200 is correspondingly disposed at the discharging ends 120, the second control valve 200 corresponds to the discharging ends 120 in number, in other words, each discharging end 120 is disposed with a second control valve 200, the pressure sensor 400 is disposed at the infusion pipeline 100, the pressure sensor 400 is located between the first control valve 200 and the second control valve 300, and the pressure sensor 400 is mainly used for testing the internal pressure of the infusion pipeline 100. The controller 500 is in signal connection with the first control valve 200, the second control valve 300, and the pressure sensor 400, respectively.

The utility model discloses an electrolyte transfusion system during operation, first control valve 200 is opened, when the electrolyte liquid level in the notes liquid bucket that discharge end 120 corresponds reaches the limiting position, the second control valve 200 that corresponds closes, after second control valve 200 when a plurality of discharge ends 120 closes, pressure sensor 400 works this moment, test infusion pipeline 100's intraductal pressure, judge when intraductal pressure value is less than the default and take place the weeping, controller 400 controls first control valve 200 and closes, it is normal to judge the infusion when intraductal pressure reaches the default, resume electrolyte transfusion system's normal work.
