Background

The radial annular surface T of the partition plate body, the steam chamber M, a radial working surface D1 around a boss C of a steam inlet window of the steam chamber M, the width W of the boss, the height H of the boss, an outer wall surface S around the boss C, a radial working surface D of the rotating ring 4 and a matching relation between the working surface D and the working surface D1 are shown in a figure (D1). The dashed lines on the rotating ring 4 indicate the steam channels on the rotating ring. The baffle body 2 is provided with a plurality of groups of steam chambers M, and a plurality of nozzles 3 are arranged in each group of steam chambers. When the rotary partition plate works, the partition plate body 2 is fixed, the rotating ring 4 rotates by a certain angle as required to open each group of steam chambers M, so that steam flows into the steam chambers M from a channel shown by a dotted line on the rotating ring 4, the steam is generally not allowed to flow into the steam chambers M from the periphery of the steam chamber M inlet boss C, and the radial annular working surface D of the rotating ring 4 is in contact sliding fit with the radial working surface D1 on the periphery of the steam chamber M steam inlet boss C of the partition plate body 2. When the rotary clapboard works under the conditions of high steam pressure and high working temperature, the radial working surface D of the rotary ring 4 is pressed against the radial working surface D1 around the window boss C of the clapboard body 2 by the axial thrust generated by the action of steam pressure difference on the rotary ring 4, the friction between the two radial working surfaces D and D1 is increased when the rotary ring 4 rotates, the mechanical properties of the currently used rotary ring and clapboard body materials are reduced when the steam temperature is higher than 350 ℃, and the matching working surfaces D, D1 on the rotary ring 4 and the clapboard body 2 are worn and cannot work normally after the working time is long.

In general, the radial working surface D on the rotating ring 4 is in sliding sealing fit with the radial working surface D1 around the inlet boss C of the steam chamber M of the partition plate body 2 in operation so as to control the steam amount entering the steam chamber M. Steam exists on the radial surfaces on the two sides of the rotating ring 4, and the steam pressure difference acts on the rotating ring 4 to generate axial force, so that the friction force of sliding when the working surfaces D and D1 rotate is increased, and the abrasion of the working surfaces D and D1 is increased. Particularly, when the steam temperature is higher than 350 ℃, the mechanical properties of the metal material are reduced rapidly, so that the working surfaces D and D1 are abraded at a higher temperature, and finally, the use requirements of the steam turbine during operation cannot be met.
