All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

As shown in fig. 1 and fig. 2, the gas-liquid detecting and adjusting mechanism of a double feed machine of the present invention includes a connector 10, a pressure sensor 20, a first valve 30, a check valve 31, a pressure pump 32, a second valve 33, a liquid storage tank 34, a liquid level sensor 21, a single chip microcomputer 40, a gas storage tank 50, a three-way valve 51, and a gas flow meter 52.

And the joint 10 is externally connected with a gas-liquid outlet of the re-feeding machine S. Preferably, the quick-change connector is adopted, so that the quick-change connector can be quickly connected and detached.

The pressure sensor 20 detects the pressure in the pipeline, and in the present embodiment, an electronic pressure sensor is used, but a pressure gauge may be used instead of the pressure sensor to adapt to manual operation.

The first valve 30, the check valve 31 and the second valve 33 are electromagnetic valves in the present embodiment, but manual valves may be used to accommodate manual operation.

The liquid storage tank 34 stores the standing-withdrawing liquid, and generally preferably adopts a cylindrical tank body, so that the inner surface of the formed tank body is cylindrical, the upper diameter and the lower diameter of the tank body are consistent, and the liquid level can be rapidly calculated through liquid level lifting.

The liquid level sensor 21 collects the liquid level in the liquid storage tank 34, and the liquid level sensor 21 is arranged in the liquid storage tank 34. . Considering that the standing liquid can disturb the liquid level sensor 21 when flowing into and out of the liquid storage tank 34, and further reduce the control precision, the upper end and the lower end of the liquid level sensor 21 are hinged with the liquid storage tank 34 respectively.

The gas-liquid outlet of the re-feeding machine, the joint 10, the pressure sensor 20 and the first valve 30 are communicated in sequence;

the check valve 31 is communicated with the liquid storage tank 34;

the second valve 33 is in communication with the pressure pump 32 and the reservoir tank 34 in this order.

In the above embodiment, the first valve 30 may be omitted, however, it is found through practical tests that if only the check valve 31 or the second valve 33 is used to control the liquid flow, there is a problem that the control is not accurate due to the excessive liquid pressure, and therefore, the first valve 30 is provided to be linked with the check valve 31 or the second valve 33, one is used for rough flow adjustment, and the other is used for fine flow adjustment, so that the flow control accuracy can be increased.

since the volume of the stagnation liquid can be regarded as a constant value in both the shuttle and the reservoir tank 34, the discharge volume in the shuttle is Δ V₂The space of the standing-retreat liquid can be regarded as being completely occupied by gas, so that the volume V of the original gas in the reciprocating machine can be calculated by the following formula₁：

P₁V₁＝P₂(V₁+ΔV₂)；

Then the volume V of the original standing-retreat liquid in the re-feeding machine is calculated according to the following formula₀：

V₀＝V_{Rated value}-V₁，V_{Rated value}The rated capacity of the re-feeding machine;

further passing through the standard value V of the stationary liquid in the re-feeding machine_{Standard of merit}Determining the volume V of the standing-retreat liquid to be supplemented_{Supplement device}：

V_{Supplement device}＝V_{Standard of merit}-V₀+ΔV₂。
