the further optimization and/or improvements to above-mentioned model utility technological scheme below:
above-mentioned limit component can be fixedly installed togather by welding and left connecting tube; Or limit component and left connecting tube connect as one.
above-mentioned limit component can be postive stop baffle; Postive stop baffle area is greater than the endoporus area of loose flange; On postive stop baffle, there is the pipeline communication hole that can make left connecting tube and right connecting tube be connected.
above-mentioned connector element can adopt bolt and nut, or/and bearing pin and cotter pin.
between above-mentioned postive stop baffle and fastening flange, can be installed with annular gasket seal; The right side of the postive stop baffle corresponding with gasket seal and the left side of fastening flange are intervally distributed with respectively sealing water wave wire casing from inside to outside.
the utility model reasonable and compact in structure, easy to use; Be connected with fastening flange by loose flange, postive stop baffle and fastening flange compressed spacing, realize pipeline docking; In docking operation, loose flange, in rotatable, the radial and axial adjustment of left connecting tube, makes flange fastener hole centering, easy to connect; And make the butt end face docking between flange intact, reduce butt seam; Need not manually repair, workload is low, and the efficiency that pipeline connects is high.
Brief description of the drawings
