It middle the step of detecting when taking gas, improves efficiency.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
In figure: rubber protecting jacket 1, take air valve ontology 2, counterbore 201, stomata 202, shrinkage hole 203, nipple 1,
Nipple 2 205, hexagonal axis 206, groove 1, sealing ring 1, spool 4, step 401, spring positioning axis 402, guiding
Bar 403, groove 405, sealing ring 25, spring 6.
Specific embodiment,
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
As shown in Figure 1, a kind of portable self closing takes air valve, comprising rubber protecting jacket 1, air valve ontology 2, sealing ring one are taken
3, spool 4, sealing ring 25, spring 6, it is described that air valve ontology 2 is taken to set hexagonal axis 206,206 top and bottom of hexagonal axis point
Nipple 2 205 and nipple 1 are not set, takes and sets stomata 202 in air valve ontology 2, and the stomata 202 divides into counterbore
201, the lower end of the counterbore 201 sets shrinkage hole 203, and 401 upper end of step of the spool 4 sets guide rod 403, the guide rod
Set sealing ring 1 in groove 2 405 between 403 and step 401,401 lower end of step sets spring positioning axis 402, spool 4 and takes gas
After valve body 2 assembles, guide rod 403 and stomata 202 are socketed, and upper end is socketed spring positioning axis after the spring 6 is packed into counterbore 201
402, the end face of step 401 is withstood in 6 end of spring, and 6 lower end of spring resists the medial surface of shrinkage hole 203, and spring 6 is past spool 4
Upper top, the sealing ring 1 of 401 upper end of step, which seals stomata 202, separates 201 gas circuit of counterbore of stomata 202 and lower end, described
The ring of rubber protecting jacket 1, which is socketed in, to be overturn the nut cap of rubber protecting jacket 1 after groove 1 and covers outside nipple 2 205, this reality
It is simple with new structure, it takes gas convenient, enormously simplifies the step of being detected when taking gas in industrial production, improve efficiency.
The tail portion of the nipple 1 sets sealing ring 25, is conducive to connect sealing with tracheae.
The spring 6 is Pagoda-shaped, and the small end of spring 6 is connect with spring positioning axis 402, and the big end of spring 6 resists contraction
The medial surface in hole 203 makes the elastic force direction of spring 6 to center convergence, avoids spring positioning axis 402 from deviating and influence to avoid sealing
Enclose the leakproofness of one 3 pairs of stomatas 202.
203 diameter of shrinkage hole is less than the outside diameter of spring 6, and spring 6 is avoided to deviate from counterbore 201.
The rubber protecting jacket 1 sets a connecting band, and one end of connecting band sets lasso, and the other end sets nut cap, when not taking gas,
Nipple 2 205 is protected in nut cap, also protects the stability of 403 nature of guide rod, avoids external action and gas leakage.
The end face of the spool 4 applies 4 energy play formula activity of spool when overcoming the elastic force of spring 6, when taking gas, opens rubber
Protective case 1 covers on the nut cap taken on the nipple 2 205 of air valve ontology 2, the container with seal to living to take air valve ontology 2
Stomata 202 press down, the guide rod 403 of synchronous drive spool 4 moves down, sealing ring 1 synchronize toward bottom offset open gas
The inlet end in hole 202, endotracheal gas enters through stomata 202 from counterbore 201 and enters in container, after taking gas,
Container is taken away, and spring 6 pushes spool 4 to rise automatically, and the inlet end of one 3 synchronous sealed stomata 202 of sealing ring takes gas rapid, takes
Jia bombardier is suddenly and simple to operation, conveniently, takes gas and sealing to carry out in a flash, greatly reduces the possibility of local gas leakage when taking gas
Property.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should all cover within the rights protection scope of the utility model.
