Abstract

The utility model discloses a vacuum accommodating device, which especially relates to a vacuum air suction valve. The vacuum air suction valve comprises a valve cover (1), a base (2) and a screw extrusion rod (3), wherein the valve cover (1) is provided with at least one through hole (11), and the middle part of the base (2) is opened. The vacuum air suction valve has the functions that when the air is sucked, the valve cover is first loosened, an air pump or a vacuum cleaner is directly covered on the valve cover to suck air, and the gas in an accommodating bag enters into the through hole of the valve cover via a through passage which is formed by the loosening of the screw extrusion rod and a T-shaped sealing gasket from the opening at the middle part of the base, so the air leakage does not occur, and the air suction effect is favorable; after air suction is finished, the valve cover is directly screwed, and the opening of the base is sealed in a way of using the screw extrusion rod to extrude the T-shaped sealing gasket, so the operation is simple and the use is convenient.

Description

A kind of vacuum extraction valve

Technical field

The utility model relates to a kind of vacuum collecting device, relates in particular to a kind of vacuum extraction valve.

Background technique

At present, be used for the device to the vacuum storage bag vacuum suction, generally all be to vacuumize with extraction pump or vacuum cleaner, such air suction mode is owing to be to seal gas with gasket seal, so in the time of need bleeding through being everlasting, valve body is easy to cause gas leakage in the time of need to separating and bleed, the dynamics of bleeding is inadequate, the long weak effect of bleeding of time that causes bleeding is bled if perhaps extraction pump is screwed on the bleeding point, so that use also very inconvenient.

The model utility content

The purpose of this utility model is to provide a kind of vacuum extraction valve, can not bleed with extraction pump or good cooperation of vacuum cleaner to solve existing gasket seal, and gas leakage causes the problem of the poor effect of bleeding easily.

For addressing the above problem, technical solution adopted in the utility model is:

A kind of vacuum extraction valve, comprise the valve gap that is provided with at least one through hole, base and the spiral depression bar of intermediate openings, described spiral depression bar is installed in the interior screw mouth of described base, the middle part of described spiral depression bar is provided with circular hole, be provided with at least one air outlet around the circular hole, be equipped with in the described circular hole can compression seal base intermediate openings T word gasket seal, gapped between the neck of described T word gasket seal and the circular hole internal diameter, described valve gap and base interfix by positioning device, the mutual UNICOM of described air outlet and through hole; The bottom surface of described base is provided with at least one stiffening rib, and the inwall middle part of described valve gap is provided with at least one stiffening rib, and described valve gap is by stiffening rib and described spiral depression bar rotary synchronous.

For making the utility model play better technique effect:

Further technological scheme is that the end that above-mentioned T word gasket seal passes circular hole is provided with globule half.

Further technological scheme is that above-mentioned air outlet is circular arc.

Further technological scheme is that above-mentioned positioning device is to be made of the flange collar on the groove circle on the base bore outer wall and the valve gap bore inwall.

The beneficial effect that adopts technique scheme to produce is: a kind of vacuum extraction valve of the utility model is when needs are bled, can unscrew first valve gap, directly extraction pump or vacuum cleaner are covered on the valve gap and bleed, the passage of formation entered the through hole on the valve gap after gas in the collecting bag became flexible by spiral depression bar and T word gasket seal from the opening in the middle part of the base, air tight, has the extraordinary effect of bleeding, after finishing when bleeding, directly tighten valve gap, spiral depression bar extruding T word gasket seal is sealed up the opening on the base to be got final product, simple to operate, easy to use.

Embodiment

In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Fig. 1, Fig. 2, Fig. 3 and Fig. 4 show an embodiment of a kind of vacuum extraction valve of the utility model: a kind of vacuum extraction valve, comprise the valve gap 1 that is provided with at least one through hole 11, the base 2 of intermediate openings and spiral depression bar 3, described spiral depression bar 3 is installed in the screw mouth 21 in the described base 2, the middle part of described spiral depression bar 3 is provided with circular hole 4, be provided with at least one air outlet 5 around the circular hole 4, be equipped with in the described circular hole 4 can compression seal base 2 intermediate openings T word gasket seal 6, gapped between the neck 62 of described T word gasket seal 6 and circular hole 4 internal diameters, described valve gap 1 and base 2 interfix described air outlet 5 and through hole 11 mutual UNICOMs by positioning device; The inwall middle part of described valve gap 1 is provided with at least one stiffening rib 13, and described valve gap 1 is by stiffening rib 13 and described spiral depression bar 3 rotary synchronous.

According to another embodiment of a kind of vacuum extraction valve of the utility model, the end that T word gasket seal 6 passes circular hole 4 is provided with globule 61 half, can make T word gasket seal 6 be not easy to be separated from fully from spiral depression bar 3 after loosening.

According to another embodiment of a kind of vacuum extraction valve of the utility model, be the shape in conjunction with spiral depression bar 3, air outlet 5 can be maximized, can be set to circular arc in air outlet 5.

According to another embodiment of a kind of vacuum extraction valve of the utility model, positioning device is to be made of the groove circle 22 on the base 2 bore outer walls and the flange collar 12 on the valve gap 1 bore inwall.

Its using method is: when needs are bled, can twist first and send valve gap 1, directly extraction pump or vacuum cleaner are covered on the valve gap 1 and bleed, the passages that form after the gas in the collecting bag is loosening by the circular hole 4 on the spiral depression bar 3 and T word gasket seal 6 from the opening at base 2 middle parts enter air outlet 5 and enter through hole 11 on the valve gap 1 again; After finishing when bleeding, directly tighten valve gap, spiral depression bar extruding T word gasket seal is sealed up the opening on the base 2 get final product, simple to operate, easy to use.
