Abstract

The utility model discloses a fine-tuning face-sealed inflatable bottle, which comprises a gas valve and an inflatable bottle; the utility model is characterized in that: the valve is face-sealed straight with the oxygen inflatable bottle mouth, and a vent-hole is arranged at the side of the valve; a gas flow channel arranged in the central part of the valve core is communicated with a V-shape fine-tuning slot positioned at the surface of the valve core, and the valve cover is connected with a valve core nut by a locator card at the bottom outside of the valve cover and the two form a face-sealed friction; the V-shape fine-tuning slot can be communicated with the vent-hole of the valve by turning the valve core to realize the fine-tuning deflated function. The seal of the valve and the bottle mouth, the valve core adopts a face-sealed structure and the utility model has the advantages of good air tightness, reasonable structure, low cost, adjusting the release gas quantity by the V-shape fine-tuning slot at the surface of the valve core, accurate and uniform gas quantity after once adjustment, safety and reliably, therefore, the aseptic oxygen inflatable bottle is widely used.

Description

Finely tune quiet face seal gas filling bottle

Technical field:

The utility model discloses the quiet face seal gas filling bottle of a kind of fine setting, is to the improvement of existing valve inside centre lathe type gas filling bottle, belongs to medical science oxygen therapy apparatus technical field.

Background technique:

The bleed valve of existing medical oxygen therapy bottle adopts valve inside or thimble deflation structure, and its shortcoming is that air-flow is not easy control, and fine adjustment is poor, and is poorly sealed, and the oxygen storage time is short, has influenced promoting the use of of transfusion oxygen therapy.

Summary of the invention:

The utility model discloses the quiet face seal gas filling bottle of a kind of fine setting, has overcome the shortcoming that sealing is poor, fine setting is bad of the oxygen therapy bottle of existing valve inside or thimble structure.

Technical solution of the present utility model is as follows: constitute the oxygen therapy bottle by bottle and air valve, wherein, air valve comprises: valve body, spool, the spool location piece, valve core nut, bottleneck nut and seal rubber pad, valve body and oxygenation bottleneck are the quiet face seal of stretched, side of valve body is provided with vent, the middle part of spool is provided with air-flow path and is connected with the V-type trimming groove that the spool face ring leaves, valve body is enclosed within spool and is connected with valve core nut by the bottom location piece outward, constitute quiet face seal friction pair, can make the vent conducting of V-type trimming groove and valve body realize the venting function by rotational valve core.

During use the syringe needle on the spool is inserted in the glue lid of infusion bottle, its vent is communicated with V-type regulating tank on the valve body, regulate discharge quantity gradually, finish even venting by rotational valve core.

Good effect of the present utility model is: valve body and bottleneck, spool adopt quiet surface seal structure, tightness is good, rational in infrastructure, cost is lower, utilize the V-type trimming groove of spool face to regulate discharge quantity, once regulate back tolerance accurately, evenly, easy to operate, safe and reliable, aseptic oxygenation bottle is extensive use of.

Description of drawings:

Fig. 1 is the utility model structure principle chart.

Fig. 2 is the utility model spool V-type trimming groove sectional view.

Embodiment:

According to Fig. 1, air valve is by valve body 2, spool 3, spool location piece 4, valve core nut 5, bottleneck nut 6 and seal rubber pad 7 constitute, the bottleneck of the gas filling bottle 1 of hard and the valve body of air valve 2 are connected for the quiet face seal of stretched, guarantee that gas does not leak, referring to Fig. 2, spool 3 middle parts are air-flow path 10, the surface of spool 3 has V-arrangement trimming groove 8 from-shallow-to-deep, the formation that links to each other with its air vent bleed passage, the top of spool 3 also is provided with transfers device handle 9, can drive spool 3 rotates, the side of valve body 2 has vent and transfers groove to be communicated with the V-arrangement of spool 3, valve core nut 5 is fixedlyed connected spool 3 by location piece 4 with valve body 2, bottleneck nut 6 is tightened in air valve on the gas filling bottle 1 by seal rubber pad 7.

Claims

1, the quiet face seal gas filling bottle of a kind of fine setting, constitute by air valve and gas filling bottle, it is characterized in that: valve body and oxygenation bottleneck are the quiet face seal of stretched, side of valve body is provided with vent, the middle part of spool is provided with air-flow path and is connected with the V-type trimming groove that the spool face ring leaves, valve body is enclosed within spool and is connected with valve core nut by the location piece of bottom outward, constitutes quiet face seal friction pair, can make the vent conducting of V-type trimming groove and valve body by rotational valve core.
