In the existing flow quick response test method, when the existing flow test technology is used for testing under the condition that the response speed is high for the micro flow test, the phenomenon of slow response in the flow test process caused by pressure oscillation caused by valve action can occur due to the valve action. Based on the above, the embodiment of the invention discloses a micro-flow quick response test method, a micro-flow quick response test device, electronic equipment and a storage medium, wherein flow tests are carried out in a multi-branch pipeline mode, and when the micro-flow quick response test method is set, a test valve with a smaller drift diameter is used for quickly balancing the pressure difference at two ends of a flow sensor so as to improve the response speed of test flow.
Example 1
As shown in fig. 1, an embodiment of the present invention provides a micro-flow rapid response test method, including:
the device comprises an air charging pipeline 1, wherein a first balance valve 11, a pressure stabilizing tank 12 and an air charging valve 13 are sequentially arranged on the air charging pipeline 1, and the input end of the air charging pipeline 1 is an air inlet;
a first branch pipeline 2, one end of the first branch pipeline 2 is connected with the output end of the charging pipeline 1, a second balance valve 21 is arranged on the first branch pipeline 2 to control the on-off of the first branch pipeline 2,
a second branch pipeline 3, one end of the second branch pipeline 3 is connected with the output end of the air charging pipeline 1, a test valve 31 is arranged on the second branch pipeline 3 to control the on-off of the second branch pipeline 3,
a third branch pipe 4, one end of the third branch pipe 4 is connected with the output end of the gas charging pipe 1, and a flow sensor 41 is arranged on the third branch pipe 4 to perform flow test on the gas flow passing through the third branch pipe 4;
a pressure sensor 7, wherein the pressure sensor 7 is used for monitoring pressure signals in each branch pipeline;

The gas circuit control at different stages of the inflation test balance is realized by arranging the plurality of branch pipelines, so that the test of the corresponding product is finished; in the gas balance stage, the effect of quick response can be achieved by making the test valve 31 maintain an open state to quickly balance the pressure difference across the flow meter caused by the actions of the first balance valve 11 and the inflation valve 13. The purpose of detecting each pressure value and each flow value in the test process is achieved by arranging the pressure sensor 7 and the flow sensor 41.
The parallel connection mode adopted in the embodiment of the invention mainly has the following considerations: when avoiding inflating, the high pressure and high flow directly reaches the product through the flow sensor, and the problem that the pressure resistance and the flow range of the flow sensor are exceeded is easily caused, so that the purpose of protecting the flow sensor can be achieved. In addition, the flow sensor of the embodiment of the invention is necessarily connected in parallel at the test valve, but cannot adopt a serial connection mode.
The provision of surge tank 12 is necessary at the time of the setup, and when the heel test stage is entered, surge tank 12 is disconnected from the former air source, and air supply operation is performed by supplying air from surge tank 12. The reason for adopting the surge tank for air supply operation is that the test effect is affected in consideration of the unstable and large fluctuation of the factory air source, so the surge tank is arranged to isolate the air source for air supply operation.
More preferably, the first balance valve 11, the inflation valve 13, the second balance valve 21, the test valve 31 and the exhaust valve 61 are two-way valves.
More preferably, the diameters of the first balance valve 11, the charging valve 13, the second balance valve 21 and the exhaust valve 61 are all smaller than the diameter of the first balance valve 11, and the diameter of the test valve 31 is smaller than the diameter of the first balance valve. The ratio between the diameter of the test valve 31 and the diameter of the first balance valve 11 is any value between 1/15 and 1/3.
In the specific setting, the path of the test valve 31 is designed to be very small, and the flow sensor 41 caused by the valve action is slowed down by adopting a small path valve, so that the problem of slow flow test response speed is caused.
More preferably, the diameter of the test valve 31 is any value between 0.1 mm and 1 mm, and the diameter of the first balance valve 11 is any value between 3 mm and 8 mm. More specifically, the diameters of the first balance valve 11, the second balance valve 21, the charge valve 13 and the discharge valve 61 were all 4mm, and the diameter of the test valve 31 was 0.5mm.
More preferably, the flow sensor 41, the time module and the pressure sensor 7 are electrically connected with the control module;
the air source device is used for performing inflation operation through a pipeline of the air inlet testing device.
And counting time information in the whole test process by adopting a time module and correspondingly judging the time information.
In the minute flow rate test, since the flow sensor 41 has a small path, the valve is operated to easily cause imbalance in pressure across the flow sensor 41, resulting in a relatively long time for testing the flow rate to a true value. Through increasing test valve 31, select the two-way valve that the latus rectum is little, the differential pressure that causes when the valve action is little, the quick balanced flow sensor 41 both ends to promote the response speed of test flow, response speed promotes approximately has 10S, can promote holistic detection efficiency. However, it takes about 20 seconds to enter the single balancing stage without using the device of the embodiment of the invention.
The micro-flow quick response testing device in the embodiment of the invention adopts a multi-branch pipeline mode to carry out flow test, and when the micro-flow quick response testing device is set, the pressure difference at two ends of the flow sensor 41 is quickly balanced by adopting the testing valve 31 with smaller drift diameter, so that the response speed of the tested flow is improved.
