Detailed Implementation
[0020] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0021] Example: Figure 1 and Figure 2 As shown, a water injection and pressure holding test mechanism for a membrane product includes a water injection test mechanism and a water pressure holding mechanism.
[0022] The water pressure maintaining mechanism includes a pipeline filter valve body, a pressure sensor 2.8 installed inside the pipeline filter valve body, the pressure sensor being connected to a water pressure gauge 2.1, and the pipeline filter valve body being provided with a valve body inlet 2.4, a valve body outlet 2.7, and an air inlet 2.2;
[0023] The water injection testing mechanism includes a fixed plate 1.5, on which four guide rods 1.18 are mounted via linear bearings 1.19. A pressure sealing structure is fixedly mounted on the four guide rods. A pressure cylinder 1.1 is mounted on the fixed plate, and the output end of the pressure cylinder is fixedly connected to the pressure sealing structure to realize the lifting and lowering of the pressure sealing structure. The pressure sealing structure includes a pipe plate 1.17 and a sealing plate 1.16. A sealing plate is fixedly mounted on the pipe plate, and a fixture 1.13 is mounted on the sealing plate. The fixture is provided with multiple product placement slots. The pipe plate is provided with an inlet 1.3 and an outlet 1.10, which are connected to the valve body inlet and outlet, respectively. Guide rails 1.4 are provided on both sides of the fixed plate, and a pressure plate 1.6 is fixedly mounted on the guide rail and moves horizontally along the guide rail. The horizontal movement of the pressure plate is driven by a translation cylinder 1.8. The pressure plate is used to cooperate with the fixture to press and seal.
[0024] A wastewater tray 1.14 is installed outside the sealing plate on the pipe plate, and a wastewater discharge port 1.9 is opened on the wastewater tray. A Z-axis buffer 1.2 is installed on the fixed plate below the pipe plate. X-axis buffers 1.7 are installed on both sides of the guide rail.
[0025] The sealing plate is equipped with a fixture positioning pin 1.12, and the fixture is equipped with a corresponding fixture positioning hole for positioning and installing the fixture.
[0026] The fixture is equipped with pressure plate positioning pins 1.11 at the four corners, and the clamping plate is equipped with corresponding pressure plate positioning holes for positioning and pressing down with the clamping plate.
[0027] The pipeline filter valve body is made of 304 stainless steel. The water pressure gauge is fixedly mounted on the bottom of the mounting plate via the water pressure gauge bracket. A valve body fixing ring is provided on the pipeline filter valve body, and the valve body is fixedly mounted on the bottom of the mounting plate via the valve body fixing ring.
[0028] In use, water enters the 304 pipe filter valve body through the inlet. After a certain amount of water is stored, air enters through the air inlet to pressurize the water to a suitable pressure. The water pressure is controlled by a pressure sensor, and the pressure gauge displays the water pressure to ensure that the water in the 304 pipe filter valve body maintains a suitable pressure. When the fixture filled with products is placed on the water injection testing mechanism and positioned by the fixture positioning pin, the translation cylinder extends, driving the clamping plate to move above the fixture. The clamping cylinder extends, driving the entire mechanism to rise, and the clamping plate positioning pin enters the clamping plate, while product 1.15 is pressed onto the clamping plate. Water at a suitable pressure enters the pipe plate through the inlet, then enters the product through the sealing plate, etc. After testing the product for a suitable time, the water flows back to the 304 pipe filter valve body through the outlet. Water overflowing from unqualified products during the test is discharged from the wastewater outlet. After the test, the clamping cylinder retracts to drive the entire mechanism to reset, and the translation cylinder retracts to drive the clamping plate to reset.
[0029] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
