Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to the specific implementation mode of the present invention further details of
Explanation.
As shown in Figure 1 to Figure 3, the bush structure for being used for filter seals detection, it is close that bush structure is located at filter
The inside of envelope property detection gas hood, the lower end of bushing 5 are equipped with the opening for being sleeved on filter, and bushing is equipped with inside and outside ventilation
Through-hole 503.
3 structure of gas hood includes gas hood cylinder 301 and the gas nozzle 304 that is located on gas hood cylinder, and gas hood cylinder 301 is opened for lower end
The cylindrical structure of mouth, lower ending opening end face are equipped with for being bonded closed ring type seal, gas hood cylinder top with detection platform
Portion is equipped with the connector 302 for being connected with lower air cylinder 4.
Vertical filter to be detected is placed in detection platform 1, the lower ending opening of filter is located in detection platform,
The stomata of detection platform is located in the lower ending opening of filter, and gas hood, which moves downward, covers filter to be detected, and gas hood passes through
The sealing ring of lower end is compressed with detection platform and is sealed, by the drop-down cylinder 2 of pull-down structure by sealing ring pressure at filter port
It is tightly sealed in detection platform, by the air inlet into filter cavity of the stomata in detection platform, by detecting the gas on gas hood
Whether mouth has gas outflow, to detect filter end with the presence or absence of leakage.As gas nozzle has gas outflow, filter to exist
Leakage is waste product.
Gas nozzle 304 is connected by tracheae with detection water box, and detecting storage in water box has water.The air inlet of detection water box passes through
Pipeline is connected with the gas nozzle on gas hood, and the detection camera of corresponding detection water box setting, detection water box are transparent water box, pass through inspection
It surveys bubble in water box and detects sealing performance, bubole analysis filter is captured automatically with the presence or absence of leakage by detecting camera.
Filter dimensions is more, and distance is very big between some gas hood inner walls and filter outer wall, influences to tie detection
Fruit is analyzed.For this purpose, being equipped with bushing 5 in gas hood, the lower end of bushing is equipped with the opening for being sleeved on filter, and bushing is equipped with
The through-hole of inside and outside ventilation ensures the air cavity range between gas hood and filter, to ensure that the bubble in detection water box out is steady
It is fixed, convenient for capturing analysis.
Bushing 5 is plastic bushing, preferably nylon jacket.Bushing is the cylindrical structure of lower ending opening, and the lower end of bushing is opened
Mouth inner edge is equipped with chamfering, convenient for filter to be inserted in.
The lateral surface of bushing is equipped with corresponding through hole and is equipped with groove, and through-hole is in groove, and the groove on bushing is annular
Groove 504, groove setting corresponding with the gas nozzle on gas hood, avoiding bushing from being bonded with gas nozzle influences normal outlet.
The top of bushing is equipped with can be along the top plate 501 of the axially adjustable position of bushing;Preferably, the top nozzle of bushing is equipped with
Internal thread, top plate are equipped with external screw thread compatible with internal thread, and the outer surface of top plate is equipped with convenient for top plate rotation process
