<p>The tapping valve (13) has a connecting flange (21) i.e. thread flange, completely or partially produced from an electrically conductive plastic material. A plastic valve housing (18) is screwed with an inlet socket (20) on the connecting flange. The valve housing is welded onto a drain socket (12) of a replaceable rectangular inner container (2) by the flange. The tapping valve is electrically grounded by a ground conductor i.e. electrical cable. The ground connector connects the connecting flange with a support frame or an outer jacket of a shipping and storage container.</p> |
