The test device 10 is used for measuring the flow restriction rate of the flow guide 20, which includes the flow restriction rate of pure water, gas or other liquid, etc., and is not described herein again. The flow restriction rate of pure water will be mainly described as an example.
Specifically, the test device 10 includes a mounting seat 100, and a mounting groove 101 is formed in the mounting seat 100. The shape of the mounting groove 101 is various, specifically, the mounting groove has a regular shape such as a circle, a square, an ellipse, and the like, and of course, the mounting groove 101 may also have other irregular shapes, wherein, in order to reduce the manufacturing difficulty of the testing device 10 and the cutting difficulty of the diversion member 20 during use, the mounting groove 101 is usually square, and a groove is generally milled on a section bar with a certain thickness. The installation groove 101 is provided with a fluid inlet 102 and a fluid outlet 103 which are communicated with the installation groove 101, wherein, in order to cover the fluid inlet 102 and the fluid outlet 103 simultaneously on the same side of the flow guide element 20, the fluid inlet 102 and the fluid outlet 103 are generally arranged on the bottom of the installation groove 101.

Thus, during the actual detection, by introducing pure water into the fluid inlet 102, the first pressure detection device 400 and the second pressure detection device 500 respectively read the water pressure at the fluid inlet 102 and the water pressure at the fluid outlet 103 as the pure water continuously flows in, and then the flow limit rate can be calculated according to the test values of the first pressure detection device 400 and the second pressure detection device 500.
Preferably, in order to improve the sealing performance between the fixing member 200 and the mounting seat 100, a sealing member 700 is disposed at the connection position of the fixing member 200 and the mounting seat 100. Wherein the shape of the sealing member 700 is adapted to the shape of the mounting groove 101 and the fixing member 200.
It should be noted that the diversion member 20 is usually a diversion cloth, and the diversion cloth is usually a woven cloth, but the testing device 10 provided by the present invention can also be used for diversion rate or flow limiting rate of other materials.

In one embodiment, the fluid inlet 102 and the fluid outlet 103 are disposed on the bottom of the mounting groove 101; in order to improve the testing accuracy of the testing device 10, the side of the fluid inlet 102 close to the mounting groove 101 is provided in an elongated shape, and the side of the fluid outlet 103 close to the mounting groove 101 is provided in an elongated shape. That is, since the membrane elements are mostly arranged in an elongated shape, the elongated fluid inlet 102 and fluid outlet 103 are closer to the membrane elements, thereby improving the accuracy of the test by the testing device 10 by simulating the actual condition of the filter element more. Preferably, the fluid inlet 102 and the fluid outlet 103 are respectively disposed at two opposite sides of the mounting groove 101.
On the basis of the previous embodiment, in order to reduce the processing difficulty, the mounting groove 101 is arranged in a square shape, and further, in order to reduce the volume of the testing device 10, the fluid inlet 102 and the fluid outlet 103 are respectively arranged on two opposite sides of the mounting groove 101 in the width direction, it can be understood that, in the testing process, the fluid inlet 102 and the fluid outlet 103 need to have a certain distance which is closer to the length of the diversion piece 20 in the membrane element, so that the measured flow limiting rate is more accurate, therefore, in order to reduce the volume of the testing device 10, the fluid inlet 102 and the fluid outlet 103 are respectively arranged on two opposite sides of the mounting groove 101 in the width direction, so that the volume of the testing device 10 can be reduced to a certain extent, thereby reducing the material cost of the testing device 10, further reducing the production cost of the testing device 10, and in addition, reducing the occupied area of the testing device 10 and simultaneously being easier to carry.

In this way, the pressing rod 320 can extend and contract between the mounting plate 121 and the base 110, so as to press or release the fixing member 200, thereby realizing the adjustment of the pressing force. Preferably, in order to facilitate the control of the pressure applied by the pressure regulating device 300, a third pressure detecting device 600 is disposed on the pressure regulating device 300.
In one embodiment, the pressure adjustment device 300 includes a pressure lever 320 and a driver 310; the driving member 310 is mounted on the mounting plate 121; the driving member 310 is connected to the pressing rod 320 in a driving manner, so that the pressing rod 320 can press the testing chamber, and the testing chamber can be adjusted.

In addition, the pressure adjustment device 300 may be configured to add a weight, such as a weight, to the fixing member 200, and determine that the pressure applied to the test chamber is different according to the added weight.
Preferably, in order to prevent the pressing rod 320 from easily fracturing the fixing member 200, the pressure adjustment device 300 further includes a pressing plate 330, and the pressing plate 330 is mounted at one end of the pressing rod 320 for contacting the fixing member 200.
