Description

{The proposed flat regulator, which serves to control the steam supply to the turbine, is placed on the axis associated with the main shaft and carrying the screw sleeve wedged on it with a screw thread, on which the gear is worn. The latter, by means of gears, connected tightly with weights, pivotally suspended in the casing, engages with the internal gear crown of the casing of the regulator, fastened to the sleeve. When the number of the circuson is changed, the gear is 1-one by the action of centrifugal force developed by the weights, nepeMi is cut by cutting the sleeve, and through the corresponding gear causes a change in the value of the cross section of the steam inlet.

In FIG. 1 shows a vertical cross section of a flat regulator; FIG. 2 is a longitudinal section of it.

An internal gear ring 19 with teeth facing the center is placed inside the casing 18 fixedly attached to the sleeve 26, which is fixed by means of dowels on the axis 27 connected to the main shaft of the turbine.

The sleeve 26 is equipped with a double thread screw thread, which is screwed on the gear 23 with long teeth

28)

And cone 24, connected in one.

On the right side, the cone 24 is provided with a plate against which the spring 25 rests.

Four gear wheels 21 interlocking with them are symmetrically placed between the ring crown 19 and the gear 23, which are connected together with the loads 20 and pivotally suspended in the casing 18.

When the turbine rotates, the system described above will rotate around its axis, which, under the influence of the centrifugal force of the weights 20, rotates the teeth 21, which, moving along the crown 19, rotate in the same direction, but at a much larger angle, the gear 23. Lastly, thanks to the presence of a screw thread will move along the axis, simultaneously dragging and the cone 24. Moving the cone along the axis accordingly raises or lowers the roller 16 and the rods 11, 13, which causes a decrease or increase in the opening of the steam inlet plate 9. Move the horse Sa 24 depends on the force of the spring 25 and the magnitude of the centrifugal force of the weights 20. A standard steam line valve (not shown in the drawing) and a manual regulating valve serve to change the speed.

a flywheel 12 screwing onto the ends of the rods 11, 13 having left and right threads. When the flywheel 12 is rotated, the ends of the rods 11, 13 move closer or farther away, which changes the size ratio between the cone position and the steam inlet cross section, and thus the speed of the turbine changes.

The spring 14 serves to better attach the roller 16 to the surface of the cone.

The subject matter of the invention.

Flat controller, different

using loads 20 pivotally suspended in housing 18 and tightly connected with gears 21 interlocking on one side with an internal gearing crown 19 of casing 18 and on the other side with gear 23 mounted on a helical cutting sleeve 26, stuck on the axis of the adjuster and fastened with to about zhuh with 1l 18.
