Description

The freight container fluid bag

Technical field

The utility model relates to a kind of packaging bag that is used for freight container, particularly a kind of freight container fluid bag.

Background technology

Freight container is mainly used in the liquid that storage need be used with fluid bag.Compare with packing barrel with the jar case, freight container is low, easy to maintenance with the fluid bag cost, and the time spent is not collapsible.All can be provided with liquid entrance and exhausr port on the fluid bag, the valve that can carry the device of liquid to be connected with the outside generally is housed on bag is imported and exported.Valve is fixed together by the bag of inside and outside flange and fluid bag, and wherein valve is connected with outward flange, and bag then is sandwiched between inside flange and the outward flange.Because valve and outward flange are two parts independent of each other, in order to prevent leak of liquid, must take corresponding seal approach between valve and the outward flange, relatively complicated from structure like this, and make troubles for the installation of valve.In addition, in order to discharge air in the bag, exhausr port will connect a freeing pipe, and freeing pipe links to each other with exterior exhaust gear again; When not needing exhaust, again freeing pipe is pulled down, then with sealing plug with on the exhaust plug, the structure that this freeing pipe and bag are separated is more complicated also, uses inconvenient.

Need to provide for this reason a kind of freight container with fluid bag to overcome above-mentioned defective.

The utility model content

The technical problems to be solved in the utility model provides a kind of freight container fluid bag simple in structure, easy to assembly.

In order to solve the problems of the technologies described above, the utility model freight container comprises the bag with liquid entrance and exhausr port with fluid bag, liquid valve is housed on the liquid entrance, liquid valve is fixed on the bag by flange, flange comprises outward flange and the inside flange of clamping bag, and outward flange and liquid valve fuse.

The integrated sealing member required between liquid valve and the outward flange and the corresponding attaching parts of having saved of liquid valve and outward flange, the structure of liquid valve and outward flange just all obtains simplifying like this, and then makes the assembling of bag also become convenient.

As an embodiment of the present utility model, flange is made of plastics, and inlays an endless metal pad in the flange.So both can increase the Joint strenght of flange, and can avoid liquid liquid that bag is adorned and plain metal direct contact to produce adverse consequences again.

Can be provided with the handle of controlled valve on the liquid valve recited above, with the opening and closing of controlling liquid valve.

A liquid valve is housed on the bag recited above, and it is positioned at the head of bag, or is positioned at the afterbody of bag, perhaps is positioned at the upper surface of bag.In another embodiment of the present utility model, two liquid valves also can be housed on the bag, one in these two valves as the feed liquor valve, and another is as liquid valve, to realize the valve special use; Perhaps, two valves are simultaneously all as injecting liquid to bag and with advancing/liquid valve that the liquid of bag is extracted out.

As further improvement of the utility model, on the exhausr port of bag freeing pipe is housed, the termination that freeing pipe links to each other with the external world has threaded connection, and threaded connection is provided with the nut that seals.As an embodiment of the present utility model, freeing pipe also is fixed on the bag by flange, flange comprises outward flange and the inside flange of clamping bag, freeing pipe and outward flange connect together, outward flange is provided with the threaded exhaust passage of inner surface belt, freeing pipe links to each other with outward flange by the threaded connection pipe of outer surface belt, and the end inside face that freeing pipe links to each other with connection pipe is provided with respective threads, and the two ends of connection pipe screw in respectively in exhaust passage and the freeing pipe.Freeing pipe directly is fixed on the bag, so just can save the trouble that each exhaust all will be reinstalled freeing pipe.

Describe the utility model in detail below in conjunction with accompanying drawing, it illustrates principle of the present utility model as the part of this specification sheets by embodiment, and other aspects of the present utility model, feature and advantage thereof will become very clear by this detailed description.
