Threaded connection, the exhaust knob are inserted in the air bleeding valve pipe, and the exhaust knob outer wall is provided with the mount of ring-type, described
Mount is provided with the first sealing ring with the air bleeding valve pipe junction, and the air bleeding valve pipe is away from wrist-watch interior side oral area and institute
State exhaust knob junction and be provided with the second sealing ring.
The exhaust knob includes exhaust plug and exhaust bonnet, and the exhaust plug is placed in the air bleeding valve pipe, institute
State air bleeding valve bore and be more than the exhaust plug external diameter, between having between the air bleeding valve inside pipe wall and the exhaust plug outer wall
Gap.
The watchcase connecting portion is additionally provided with the passage and the installing port being connected outside wrist-watch, the air bleeding valve pipe
Coordinate with the installing port gap.
First sealing ring, the second sealing ring are the rectangular annulus in cross section.
The compression elastic piece is compression spring.
The watchcase connecting portion is connected with the delivery valve seat spiral.
The number of air hole is two.
First sealing ring, the second sealing ring are quality of rubber materials.
The utility model has the advantages and positive effects of：During normal use, by being vented knob and delivery valve seat spiral shell
Screw tightly, the compression elastic piece on air bleeding valve pipe is compressed, so that the first sealing ring, the second sealing ring compress, play
Waterproof action；When Divers carry out helium-oxygen diving, helium gas molecules enter in underwater watch with the intensification of submerged depth, when
When Divers float, pressure gradually rises in wrist-watch, by unscrewing exhaust knob, makes the first sealing ring, the second sealing ring not
Seal again, helium gas molecules in table are discharged, while by controlling the ventilation gap between exhaust knob and air bleeding valve pipe, ensure water
Molecule does not enter in table；Have the advantages that it is simple in construction, easy to use, improve diving security while ensure waterproof effect.

Embodiment
As Figure 1-3, the utility model includes air bleeding valve 1 and watchcase connecting portion 2, air bleeding valve 1 include delivery valve seat 3,
Air bleeding valve pipe 4 and exhaust knob 5, watchcase connecting portion 2 are provided with the passage 6 with being connected inside wrist-watch, watchcase connecting portion 2 and row
Air valve seat 3 is threadedly coupled, and is connected between delivery valve seat 3 and air bleeding valve pipe 4 by compression elastic piece 7, and compression elastic piece 7 is sheathed on
It is vented on knob 5, delivery valve seat is threadedly coupled with exhaust knob 5, passes through screw thread between fixed delivery valve seat and exhaust knob 5
Length, the height that control exhaust knob 5 can screw out, prevent exhaust knob 5 screws out from excessively causing space excessive in discharge helium
Water is set to enter inside watchcase simultaneously.
It is vented knob 5 to insert in air bleeding valve pipe, exhaust knob 5 outer wall is provided with the mount 8 of ring-type, mount 8 and exhaust
