Embodiment Construction

[0019] The present invention will be further described now in conjunction with accompanying drawing.

[0020] Such as figure 1 and 2 As shown, the present invention provides a control system for controlling the flow rate, which includes: a liquid crystal control panel 7, a circuit board 1, a mounting plate 10, a safety valve 8, a first flow sensor 2, a first proportional valve 5, The first air intake block 4 , the first normally closed switch valve 3 , the second flow sensor 11 , the second proportional valve 14 , the second air intake block 13 , the second normally closed switch valve 12 , and the air outlet block 9 . Such as figure 1 As shown, the liquid crystal control panel 7 is installed on the panel 6, and the panel 6 is fixed on the outside of the mounting plate 10 (that is, the side outside the vertical paper surface), and the circuit board 1 is installed on the mounting plate 10. The inner side of the board 10 (i.e. the side that is vertical to the inside of the pa...

Abstract

The invention relate to a control system used for flow control. The system comprises a liquid crystal control screen (7), a circuit board (1), an installation board (10), a safety valve (8), a first flow sensor (2), a first proportional valve (5), a first air inlet block (4), a first normally-closed switch valve (3), a second flow sensor (11), a second proportional valve (14), a second air inlet block (13), a second normally-closed switch valve (12) and an air outlet block (9). The first flow sensor (2) and the second flow sensor (11) are installed at the bottom of the air outlet block (9), the first air inlet block (4) is installed between the first flow sensor (2) and the first proportional valve (5), and the first normally-closed switch valve (3) is installed beside the first air inlet block (4). The second air inlet block (13) is installed between the second flow sensor (11) and the second proportional valve (14), and the second normally-closed switch valve (12) is installed beside the second air inlet block (13).

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a control system for controlling flow. Background technique [0002] At present, the existing control system generally uses a mechanical structure to adjust the individual flows of various gases, and then outputs them together. This method produces the problem that the concentration needs to be calculated manually, which is relatively complicated. Contents of the invention [0003] The object of the present invention is to provide a control system for flow control in order to solve the problem that the existing control system cannot automatically display the concentration value. [0004] The invention provides a control system for controlling the flow rate, the system includes: a liquid crystal control panel, a circuit board, a mounting plate, a safety valve, a first flow sensor, a first proportional valve, a first air intake block, a first constant Closed on-off val...
