Description

Technical Field

[0001] The utility model relates to the technical field of precision filter detection devices, in particular to a precision filter sealing detection device. Background Art

[0002] In order to ensure the safety and effectiveness of the filter, it is necessary to conduct corresponding tests on the filter. The general test items of the filter are appearance, particulate contamination, filtration rate (i.e. filtration performance), leakage (i.e. sealing), flow rate, and tensile strength. The sealing test of the filter is an important test component.

[0003] The existing Chinese patent CN216207358U discloses a precision filter sealing detection device, which selects a sleeve rod of suitable specifications at the bottom of the connecting pipe and docks them, and then the cylinder drives the connecting pipe and the sleeve rod to move downward until the sleeve rod is stuck to the filter surface, and the high-pressure gas is transported to the inside of the connecting pipe through the air pipe, and enters the inside of the sleeve rod and the filter surface. If the filter surface has good sealing, the air is completely blocked. If the sealing is defective, the gas passes through the filter and enters the inside of the support rod. The detection data of the air flow sensor changes to obtain the detection result;

[0004] However, the above-mentioned precision filter sealing detection device places the filter on a base, and uses the filter body to block the connection between the base and the support rod. Therefore, the specifications of the base should match the specifications of the filter. However, the above-mentioned precision filter sealing detection device only selects the corresponding sleeve rod according to the specifications of the filter, and does not select the base, which may easily lead to the filter being unable to block the connection between the support rod and the base well.
