In the following description to illustrated embodiment, with reference to the accompanying drawing that forms this paper part, and embodiment illustrates with diagramatic way in described accompanying drawing.Should be appreciated that because under the situation that does not break away from the spirit and scope of the present invention, can carry out structural change, so can utilize other embodiment.
Illustrate and described exemplary coupling assembly 10 referring to figs. 1 to Fig. 9.Coupling assembly 10 comprises container insert 12, allocation units 14 and dip-tube 16.In the exemplary embodiment, container insert 12 is constructed with relative to each other the function that is connected fast/separates with allocation units 14.
For example, as shown in Figure 1, allocation units 14 comprise port one 27, and this port one 27 is constructed to be permeable to accept which is provided with the adapter 57 of screw thread.The opposite end of adapter 57 comprises attaching parts structure 58, and described attaching parts structure 58 is configured to be connected with attaching parts 59.In the exemplary embodiment, attaching parts 59 is a kind of quick connection/separation attaching partss, for example, disclosed attaching parts in the U.S. Patent No. of submitting on March 10th, 1,999 6,231,089, the full content of this patent is incorporated among the application in the reference mode.
In addition, allocation units 14 comprise vent window 79, and described vent configurations becomes to accept to be provided with the adapter 49 of screw thread thereon.The opposite end of adapter 49 comprises and is used for the band barb surfaces 47 that is connected with the flexible pipe (not shown), described flexible pipe and then be connected to such as gas sources such as air source.
In the exemplary embodiment, coupling assembly 10 provides a kind of semiclosed system that is used at container distribution and stored contents thing.In illustrated embodiment, coupling assembly 10 is not a bounded system, and wherein, dip-tube 16 and container insert 12 do not have shut off valve.Coupling assembly 10 is included in the transportation and dip-tube 16 and container insert 12 to be carried out the leak free transportation covers 13.Because in dip-tube 16 and container insert 12, do not have any disconnecting valve, so, cover 13 and common of short duration time durations when allocation units 14 not being connected to container insert 12 as yet having removed transportation, the content with container insert 12 joining containers can be exposed to container user outward.
When being in coupled condition, there are following three kinds of conventional configurations, be used to manage steam and the potential user who contacts with container contents:
● the vent window of Chang Kaiing fully, it provides the air intake that enters drum, the identical opening dissipation that allows steam to pass through via air inlet simultaneously;
● through the apneustic vent window of check, the air check control setup that it normally is incorporated in container insert or the allocation units is used to allow vent air to enter in the container, but does not allow steam or container contents to come out via this ventilation orifice; Perhaps
● the vent window of band valve, it comprises that one enters isolation and combination leak free air draft flow path in the allocation units via the container insert, it can have external port.For example, can use fluking type exit skirt (MPT) and allow the user to have following three kinds of selections that are used to manage the pressure condition in the drum potentially: (1) only with vapor discharge to atmosphere, (2) check valve is installed in port, this check valve allows in the air admission drum, but do not allow steam to come out (if the overturning situation takes place from identical port, can make seal of vessel like this), perhaps (3) make vapor flow paths vertically be deep into a control position, for example air scrubber or filter (this option can provide a kind of method so that apply the layer of inert (for example, nitrogen) of " blanket gas " in case oxidation to container contents for the end user).
For these several options, the vent window of Chang Kaiing does not provide the leak free container fully, although this option can be cheap.The vent window option of band valve provides maximum comformability, although it can comprise trading off between flow and the expense.Apneustic vent window through checking is the solution between vent window that opens wide fully and the vent window of being with valve.
Coupling assembly 10 can comprise the discretionary choices in these ventilation options.In the shown and described example of this paper, coupling assembly 10 comprises the vent window option of being with valve.
Coupling assembly 10 can be applicable to technical purity grade (IPG) application, although use certain material can also make coupling assembly 10 can be used in the chemical system of high purity grades (HPG).In the exemplary embodiment, coupling assembly 10 also is designed to and can obtains department of Transport (DOT) and/or United Nations (UN) authentication with various container dimensional.
