Description of drawings
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the force-applying piece in the embodiment and the structural representation of compressing member.
Embodiment
A kind of battery diaphragm ventilation property test device as shown in Figure 1, comprises the container 5 of contain fluid, support 4, conduit, compressing member 12 and the force-applying piece 11 of support vessels 5.Conduit comprises the rubber tube 3 of an end and container 5 connections, the glass tube 2 that an end is connected with rubber tube 3, and rubber tube 3 is a flexible pipe, container 5 can be perched, thereby produce hydraulic pressure in conduit.
The structure of force-applying piece 11 and compressing member 12 as shown in Figure 2.Compressing member 12 comprises pressing plate 107, supporting bracket 108.Pressing plate 107 is provided with central shaft 1071, is with spring 105 on the central shaft 1071; Also offer air-vent 106 on the pressing plate 107; Also be provided with groove on the pressing plate 107 and be used to install O RunddichtringO 13.Supporting bracket 108 has the end that perforation is used for fixing glass tube 2; Also be equiped with valve 109 on the supporting bracket 108.Valve 109 also can be installed on the glass tube 2.
Force-applying piece 11 comprises rotary handle 101, screw rod 102, fixed cover 103, thread bush 104.Wherein, screw rod 102 and thread bush 104 cooperates, and screw rod 102 passes fixed cover 103, and fixed cover 103 and thread bush 104 are fixture, and rotary handle 101 and screw rod 102 are movable part.
During said apparatus work, battery diaphragm to be tested is placed between supporting bracket 108 and the pressing plate 107, operation rotary handle 101 drives screw rod 102 rotations, and screw rod 102 moves down.After screw rod 102 moves down, behind the upper surface that touches pressing plate central shaft 1071, press pressing plate 107 and also move down, the sealing ring 13 that is fixed on the pressing plate 107 is pressed on barrier film on the supporting bracket 108, and seals with the external world.At this moment, the lower surface of battery diaphragm contacts with space in the glass tube 2, and glass tube 2 is communicated with container 5, and relative upper surface contacts with space in the air-vent 106, and air-vent 106 is in communication with the outside.When filling liquid and the lower surface generation hydraulic pressure at battery diaphragm in the container 5, liquid or the gas that is sealed in the glass tube 2 permeate from the barrier film of test and discharge from air-vent 106.The hydraulic pressure when testing by setting and the area of barrier film write down the needed time of liquid level decline desired location in the container 5, thereby measure the gas permeability of barrier film.
One end of spring 105 is fixed on the thread bush 104, and the other end is fixed on the central shaft 10071.When screw rod 102 moves up when returning, move on the spring band dynamic pressure plate 107, form the space at pressing plate 107 and 108 of supporting brackets, conveniently pick and place barrier film.
The break-make of control air-flow adopted stainless steel ball valve when valve 109 was used to test.
Fixed cover 103 is used for screw 102 and moves vertically, avoids O RunddichtringO 13 discontinuity everywhere, influences sealing effectiveness.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
