Problems solved by technology

In the prior art, a filling valve is only connected to the material tank through one pipeline, that is, a single-channel structure, which has the following problems: 1. The flow rate that can pass through a single channel is limited, the efficiency is low, and it cannot be adapted to the filling of large barrel containers. 2. The control valve is commonly used as a single-stage valve, that is, a switch valve with only two working states of fully open and fully closed. When the container bottle is about to be filled, the liquid flowing out of the pipeline still maintains the maximum flow and velocity, and the liquid is easy to Overflow due to excessive perfusion; 3. Use a two-stage valve instead of a single-stage valve to increase the half-open working state to control the flow rate, but the two-stage valve is expensive, which is several times or even ten times the price of a single-stage valve

Embodiment 1

[0014] Embodiment one, such as figure 1 Shown is a two-channel quantitative filling device.

[0015] The quantitative filling device of the present invention has a liquid inlet pipe 1 for liquid to flow in, liquid flows out to a liquid outlet pipe 5 of the filling valve, and two circulation pipes 21 and 22 connecting the liquid inlet pipe 1 and the liquid outlet pipe 5, The liquid inlet ends of the flow pipes 21 and 22 are connected with the liquid inlet pipe 1, the liquid outlet ends of the flow pipes 21 and 22 are connected with the liquid outlet pipe 5, and the flow meters 31 and 32 and the control valve 41 are respectively installed on the flow pipes 21 and 22 , 42, the flow meters 31, 32 send the detected flow signals to the control valves 41, 42 to control the flow state of the flow pipes 21, 22, and the flow meters 31, 32 are in the front pipeline of the control valves 41, 42.

[0016] When the filling starts, the control valves 41 and 42 are opened, and the filling fl...

Embodiment 2

[0017] Embodiment two, such as figure 2 Shown is a three-channel quantitative filling device.

[0018] There are three flow pipes 21, 22, 23 connecting the liquid inlet pipe 1 and the liquid outlet pipe 5, and flow meters 31, 32, 33 and control valves 41, 42, 43 are respectively installed on each pipe. All the other are the same as the first embodiment.

[0019] When filling, the control valves 41, 42, 43 are opened, and the filling flow reaches the maximum. When the flow meters 31, 32, 33 detect the first value signal, the control valve 43 is closed, while the control valves 41, 42 remain open. state, the filling flow decreases. When the flow meters 31 and 32 detect the second value signal, the control valve 42 closes, while the control valve 41 remains open, and the filling flow is minimum. When the flow meter 31 detects the second value signal When the three-value signal is used, the control valve 41 is closed, and the filling stops.

[0020] The beneficial effect is th...

Abstract

The invention relates to a quantitative filling device. The quantitative filling device is provided with two or more than two circulation pipelines to connect a liquid inlet pipe and a liquid outlet pipe, all the pipelines converge to a same filling valve for filling so that the filling flow is increased, the filling efficiency is improved, multilevel control is achieved, the cost is reduced, and the control is convenient.

Description

technical field [0001] The invention relates to a quantitative filling device and a filling method thereof, in which multiple filling channels confluence in one filling valve for filling. Background technique [0002] The filling machine has a material tank for storing liquid and a filling valve for filling. The material tank and the filling valve are connected by a pipeline. There is a flow meter on the pipeline to measure the flow of the liquid and control the opening of the pipeline. closed control valve. In the prior art, a filling valve is only connected to the material tank through one pipeline, that is, a single-channel structure, which has the following problems: 1. The flow rate that can pass through a single channel is limited, the efficiency is low, and it cannot be adapted to the filling of large barrel containers. 2. The control valve is commonly used as a single-stage valve, that is, a switch valve with only two working states of fully open and fully closed. W...
