Description

Technical Field

[0001] The utility model belongs to the technical field of air tightness detection, and more specifically, relates to an air tightness detection device suitable for an ultrafiltration system. Background Art

[0002] In the ultrafiltration system, air tightness is a very important performance indicator, because if there is a leak in the system, it will not only affect the filtration effect, but may also cause system failure or damage. Therefore, it is necessary to perform an air tightness test on the ultrafiltration system to prevent the leakage of the ultrafiltration system and the ultrafiltration membrane package from adversely affecting the product. The existing connection method of the air tightness test device suitable for the ultrafiltration system is to connect the compressed air terminal to the pressure reducing valve → air filter element → compressed air air pipe → ultrafiltration system air tightness test port, run the "air tightness test" program through the control panel, open the compressed air valve and slowly adjust the pressure reducing valve to make the pressure reach the test pressure range, close the compressed air valve and click the test button on the ultrafiltration system control panel to perform an air tightness test.

[0003] Existing application number CN202023308508.8 The utility model discloses an air tightness detection device for an ultrafiltration system unit, which relates to the technical field of ultrafiltration system detection equipment, including a base plate, a universal wheel is fixed to the bottom end of the base plate, and an electromagnetic slide rail is installed on the top of the base plate, the outer wall of the electromagnetic slide rail is sleeved with a slide seat, and a fixed rod is fixed on one side of the slide seat, a reset spring is installed inside the fixed rod, and a No. 2 fixed rod is fixed on one side of the reset spring, and a moving block is fixed on one side of the No. 2 fixed rod, and a mounting bracket is provided at one end of the electromagnetic slide rail. The utility model effectively solves the problem of lack of efficient detection device by arranging electromagnetic slide rail, slide seat, fixed rod, reset spring, No. 2 fixed rod, flaw detection head and moving block, and effectively solves the problem of lack of automatic marking structure by arranging marking pen, turntable, micro motor, micro electric push rod, cross plate, limit block and pressure sensor.

[0004] Based on the above, when the existing air tightness detection device suitable for ultrafiltration system is pressurized for testing inside the device at the compressed air terminal, the inside of the device is always in a high-pressure state, which makes the pressure reducing valve, air filter housing seal, compressed air air pipe and air pipe interface have the risk of leakage. If the air tightness test of the ultrafiltration system fails due to leakage, it needs to be processed and re-tested, which affects the detection efficiency. Moreover, after the test is completed, a pressure reducing valve is usually used to release the pressure, and the pressure reducing valve releases the pressure relatively slowly, which affects the efficiency.
