The back of the precision digital display flowmeter 7 is fixedly connected to the right side of the front surface of the aluminized iron plate 1. A micro precision digital display pressure gauge 8 is fixedly connected to the right side of the front surface of the aluminized iron plate 1. A flat micro-porous membrane fixture 9 is arranged on the right side of the micro precision digital display pressure gauge 8. The effective test area of the specially designed flat micro-porous membrane fixture 9 can reduce calculations and conveniently and efficiently obtain test data. At the same time, the device has a simple structure, reasonable assembly and matching, is very convenient for installing and testing samples, has a fast test speed, accurate test results, good repeatability and linearity, and high test efficiency, greatly improving work efficiency and test cost.

[0024] In order to ensure the connection between the gas purification pressure regulating valve 4, the first-stage precision pressure regulating valve 5, the second-stage precision micro gas pressure regulating valve 6, the precision digital display flowmeter 7 and the micro precision digital display pressure gauge 8, the gas purification pressure regulating valve 4, the first-stage precision pressure regulating valve 5, the second-stage precision micro gas pressure regulating valve 6, the precision digital display flowmeter 7 and the micro precision digital display pressure gauge 8 are all connected through the connecting pipeline 10. The connecting pipeline 10 can connect the above-mentioned unit structures, and at the same time, the connecting pipeline 10 can firmly seal each connection, ensuring the stability of the device during later use.

[0025] In order to facilitate the rapid installation or disassembly of the flat microporous membrane fixture 9 by the staff, a quick insertion tube is used to connect the micro precision digital display pressure gauge 8 and the flat microporous membrane fixture 9. The quick insertion tube has the advantages of simple operation, convenient installation, good sealing performance, safety and reliability, and high stability. Therefore, due to the setting of the quick insertion tube, the staff can quickly install or disassemble the flat microporous membrane fixture 9.

[0026] In order to facilitate the overall sealing and tightening of the flat microporous membrane fixture 9, a silicone sealing pad is provided on the flat microporous membrane fixture 9, and a handle for locking is also provided. The silicone sealing pad can ensure the sealing effect of the flat microporous membrane fixture 9, and at the same time, the handle also facilitates the staff to tighten the whole flat microporous membrane fixture 9.

[0027] In order to facilitate efficient calculation and quickly read the test results, there is a circular hole in the middle of the silicone sealing pad provided inside the flat microporous membrane fixture 9. The area of the circular hole is the effective test area of the filter membrane. The effective test area of the filter membrane in the flat microporous membrane fixture 9 is specially designed to facilitate efficient calculation and quickly read the test results.

Because it is fixedly installed, the staff can use screws or other fixing structures to install it on the aluminized iron plate 1. Therefore, the disassembly and assembly of the above-mentioned several groups of devices can be realized. When the above-mentioned several groups of devices are damaged, the staff can disassemble them, which is convenient for the staff to repair or replace them.

[0029] The electrical components mentioned in this article are all electrically connected to the external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.

[0030] In use, first place the filter membrane between the silicone gaskets, clamp the flat microporous membrane with the silicone gaskets, put the sample together with the silicone gaskets into the flat microporous membrane fixture 9, install the pressing part, and then lock the upper and lower parts of the flat microporous membrane fixture 9 through the handle. Thus, the locking of the sample is completed. Then, the staff uses a quick insertion tube to connect the flat microporous membrane fixture 9 and the device. Subsequently, first open the external air source pressure valve, and the test gas will be provided through the air inlet pipeline 2. Then open the air inlet pneumatic slide valve 3 to input clean compressed air. Then adjust the gas purification pressure regulating valve 4 to the specified value. Subsequently, perform the first-stage pressure regulation. By adjusting the first-stage precision pressure regulating valve 5, the pressure to be measured can be adjusted to the required test pressure value. Then, fine-tune the test pressure to the required test value according to the required pressure to be measured. The micro-adjustment of the gas flow rate is mainly carried out through the second-stage precision micro gas pressure regulating valve 6. The main purpose is to carry out the micro-adjustment of the test pressure to be measured through the adjustment of the micro gas flow rate. Observe the micro-precision digital pressure gauge 8 to reach the test pressure, and observe the precision digital flowmeter 7. After waiting for a period of time, read the gas flux of the flat microporous membrane at the specified test pressure value. Thus, the test of the gas flux of the flat microporous membrane is completed.
