Description
Technical field
The utility model belongs to the tobacco leaf storage technical field, is specifically related to a kind of tobacco leaf storage tent and charges and discharge the gas joint.
Background technology
After the tobacco leaf harvesting baking, for assorted flavor of the green grass or young crops of removing tobacco leaf and excitant, need refine tobacco leaf, the alcoholization time is 1-3.Tobacco leaf is rich in nutriment and is easy to infested; Under the hygrothermal environment, tobacco leaf is easy to produce and goes mouldy in addition.
Traditional method of killing the tobacco leaf insect is stifling with phosphine gas, but phosphine severe toxicity and inflammable and explosive damages to producers easily, and in tobacco leaf, has residual.Adopt the sealing storage practice that insect and the moisture that tobacco leaf is wrapped in the isolated external world in the sealing tent got into the cigarette buttress, but Vermins-proof mildew-proof; Can also charge into inert gas in the tent in sealing and oxygen concentration is reduced to rapidly kill insect and the mould in the tobacco stacking in the sealing tent below 2%, or in the sealing tent, place air conditioning agent and regulate oxygen concentration, humidity Vermins-proof mildew-proof.Thus it is clear that, realize that the green insecticidal degerming must guarantee that tobacco leaf stack sealing is good.
The main tent sealing tobacco leaf stack that uses in existing the production, tent is divided into counterdie and cover film, utilizes method such as heat seal to seal cover film and counterdie, and tobacco leaf is stacked in the seal cavity.For disinsection mold-proof and improve tobacco-alcoholizing quality, often need open one or more pores inflation or venting in the sealing tent on the sealing tent, how to guarantee that pore place sealing becomes in the production relatively stubborn problem.The method of being adopted at present is that gas ducting or pump-line were directly from inside to outside penetrated tent, and the pore that adopts adhesive tape to cross tent in duct penetration then carries out adhering and sealing on every side.The method operating process is more loaded down with trivial details, and bigger pressure can't be born in the junction.The method not only is not easy to operation, and can't guarantee to seal the air-tightness in the cigarette buttress.
The utility model content
The utility model technical problem to be solved is to the above-mentioned deficiency that exists in the prior art, provides a kind of tobacco leaf storage tent to charge and discharge the gas joint, and it is simple in structure, is easy to Fast Installation, and can guarantee that the tent sealing is good.
Solving technical scheme that the utility model technical problem adopted and be this tobacco leaf storage tent charges and discharge the gas joint and comprises perforate on the base that has male-pipe and sealing gasket, the tent, is placed on tent outer sealing gasket, internal thread flange and valve; Wherein sealing gasket is enclosed within on the male-pipe of base; Male-pipe on the base puts sealing gasket more successively after passing the perforate on the tent, is threaded with the internal thread flange; Outer tube joint on the internal thread flange is connected with valve, forms to charge and discharge the gas joint.
Preferably, this tobacco leaf storage tent charges and discharge the gas joint and also comprises the support that is placed in the tent, and base is rack-mount.
Preferably, said internal thread flange is fitted with the screwed pipe on the base mutually, and the internal thread flange outer diameter is fitted with the internal diameter of valve mutually.
Preferably, the aperture of the inside and outside sealing gasket that is provided with of said tent equals the external diameter of male-pipe on the base and the internal diameter of internal thread flange.
Preferably, the male-pipe height is identical on perforate on said tent height and the base, and the perforate external diameter is not more than the male-pipe external diameter.
Preferably, said support bottom is provided with a sheet metal, and the support upper end is a circular arc, and base is installed in the circular arc of support.
Preferably, the inside and outside sealing gasket of said tent is silicagel pad, rubber blanket, tetrafluoroethene pad or aramid fiber pad.Charging and discharging after the gas joint installs like this, forming soft the contact between inside and outside silicagel pad and the tent, sealing strengthens.
Preferably, said valve is the spring one way stop peturn valve, and valve is bonding through adhesive and internal thread valve.The effect of spring one way stop peturn valve is to prevent that gas from flowing backwards and the leakage of the interior gas of sealing tent.On tent, adorn an inflation and air extractor respectively, when on tent, aerating device being installed, valve is bonded on the internal thread flange with adhesive; When being installed on tent, outside air extractor then valve is enclosed within on the internal thread flange in the other direction.
Preferably, said sealing gasket and internal thread flange periphery can be polygon or circular arc.
Further preferably, said sealing gasket and internal thread flange periphery are circular.
The beneficial effect of the utility model is: it is simply rapid to make tent charge and discharge the gas process operation, and sealing effectiveness is good.Use helicitic texture to make closely contact between the sealing gasket, avoid gas leakage.
Description of drawings
Fig. 1 is for charging and discharging the rigging position graph of a relation of gas joint in specific embodiment of the utility model.
Among the figure: the 1-support; The 2-base; Sealing gasket in the 3-tent; The 4-tent; 5-tent external seal pad; 6-internal thread flange; The 7-valve; The 8-male-pipe.
Embodiment
For making those skilled in the art understand the technical scheme of the utility model better, the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1; In the present embodiment; This tobacco leaf storage tent charges and discharge the gas joint and comprises the support 1 that is placed in the tent and be installed in the base that has male-pipe 82 on the support 1 and be enclosed within the sealing gasket 3 on the male-pipe 8 of base 2; With the position perforate of screwed pipe 8 height such as grade of base 2, the base male-pipe 8 that has sealing gasket 3 passes from tapping, on screwed pipe 8, puts sealing gasket 5, internal thread flange 6 and valve 7 more successively on tent 4.
Said internal thread flange 6 is fitted with the male-pipe 8 on the base 2 mutually, and internal thread flange 6 external diameters are fitted with the internal diameter of valve 7 mutually.Tent 4 inside and outside sealing gaskets 3 that are provided with and 5 aperture equal the external diameter of male-pipe 8 on the base 2 and the internal diameter of internal thread flange 6.On the tent on perforate height and the base 2 male-pipe 8 highly identical, and the perforate external diameter is not more than male-pipe 8 external diameters.
