The gate control unit has body with bypass channel for pass on fluid medium, this is equipped with suitable means for mounting at the pipeline and guides as plates made of stable to corrosion and/or abrasive wear material, those are fixed in the body practically at right angle to geometrical axis of the channel and have openings corresponding to the channel in shape and the area of flow-through cross-section, slide plate made of stable with respect to corrosion and/or abrasive wear material, this is placed between the guide plates in slide setting, and suitable guide of reciprocal displacement of the plate along the guide plates between the positions ôclosedö and ôopenedö. The bypass channel of the body is lined with shells, those are at least partially made of stable to corrosion and/or abrasive wear material, are installed inside the body with sealing, and are serve as supports for the guide plates and are fixed against axial shift by support threaded bushings, and the slide plate has in the upper section an opening for the fluid medium pass. |
