When the control valve is arranged, the control valve is opened during filling, and liquid in the loop can flow circularly during filling; when the control valve is opened, the liquid flowing out from the filling head 3 is divided into two paths, one path flows through the control valve, flows through the quantitative control valve 2 and then flows out from the liquid outlet 23, the other path flows into the quantitative cavity 12 through the quantitative cavity connecting port 32 and the quantitative cavity inlet 121, and then flows through the quantitative control valve 2 through the quantitative cavity outlet 122 and then flows out from the liquid outlet 23.
In the present invention, when the residual liquid is not required to be pumped out and drained, the second piston 310 can be always in the closed state at the left side.
The detailed working process of the invention is as follows:
when not filling: the first piston 36 in the filling head 3 pushes the first control valve 37 to be opened, the second piston 310 moves to the left, and the third piston 24 in the quantitative control valve 2 pushes the second control valve 26 to be opened; liquid enters the filling head 2 from the liquid inlet 31, when a control valve is not arranged at the quantitative control valve connecting port 33 or the control valve is arranged but is opened, the liquid flows in two paths, one path flows through the quantitative control valve connecting port 33, flows through the left inlet 21 of the quantitative control valve 2, enters the quantitative control valve 2 and then flows out and circulates through the liquid outlet 23; the other path flows through the inlet 121 of the quantitative cavity via the connection port 32 of the quantitative cavity, and then flows through the right inlet 22 of the quantitative control valve 2 via the outlet 122 of the quantitative cavity, and then flows out of the circulation via the liquid outlet 23 of the quantitative control valve 2. Thus, when not filled, the liquid in the pipeline is always in a circulating state. When the residual liquid in the filling head needs to be removed, the second piston 310 is moved to the right, so that the filling port 34 is communicated with the liquid discharge port 35, and then the residual liquid in the filling head is pumped out by a vacuum pump, so that the pollution is avoided.
During filling: the first piston 36 in the filling head 3 moves to the left, the first control valve 37 is driven to be closed, or the first control valve 37 is rebounded by the spring 39 to be closed, the second piston 310 moves to the left, the third piston 24 in the quantitative control valve 2 moves to the left, the second control valve 26 is driven to be closed, or the second control valve 26 is rebounded by the spring 39 to be closed, liquid enters the filling head 2 from the liquid inlet 31, and due to the fact that the first control valve 37 is closed, the liquid can only enter the quantitative control valve 2 from the quantitative control valve connecting port 33 and enters the quantitative control valve 2 through the left inlet 21 in the quantitative control valve 2, and due to the fact that the second control valve 26 is closed, the liquid flows. After the liquid in the quantitative cavity is pressurized by the pressurizing piston, the liquid flows back to the filling head through the inlet 121 of the quantitative cavity and the connecting port 32 of the quantitative cavity, and the liquid entering from the liquid inlet 31 is positioned on one side of the first control valve 37, so that liquid circulation is formed; the reverse flow of liquid is on the other side of the first control valve 37, and the reverse flow of liquid can only be filled through the filling port 34 because the second piston 310 moves to the left to block the liquid outlet 35.
The foregoing detailed description is given by way of example only, to better enable one of ordinary skill in the art to understand the patent, and is not to be construed as limiting the scope of what is encompassed by the patent; any equivalent alterations or modifications made according to the spirit of the disclosure of this patent are intended to be included in the scope of this patent.
