SU147A1 - Sliding steam valve with pistons sliding on its rolling pin and washers resistant for them - Google Patents

Description

The proposed sliding steam valve with 11Orn1 sliding on its rolling pin and thrust washers for them is intended to prevent decelerating phenomena in the locomotive cylinders when the steam locomotive runs without steam and to suck in them gases from the smoke box; this should increase the length of the path traveled by the steam-free locomotive, and improve the operation of the spool bushings and engine cylinders, as well as the driving mechanism; as a result, there should be savings in fuel and repairs when the engine is exploited.

FIG. 1, the spool is shown in longitudinal section, when working with steam, in FIG. 2 - when operating without steam, and in FIG. 3 is a side view of the spool disc.

The spool consists of two spool discs A, supplied with ordinary spool, spring rings, worn loosely on the spool rolling pin - and sliding along it between the thrust H1aibs in-in. The washers are pressed against the conical sharpening of the rolling pin with nuts, with the lock nuts / and the checks e. When the regulator is opened, the fresh steam entering the special tube between discs A will move them

to thrust washers e-in and presses them on lapping i: -c. The ego pressing of the discs A is maintained during the whole movement of the spool rolling pin - “, and the discs A work as in the usual, non-sliding, spool (Fig. 1). In order to see the landing of spool disks A on the shields in without impacts, these disks have cylindrical undercuts B (Fig. 2) and through holes O on the outer planes. and, squeezing the steam penetrating here through the holes of O, form vapor buffers that soften the fit. When the regulator is closed and the steam inlet is shut off, the discs A are shifted by pucks into each other and stopped. At the same time, spool discs A will open fully the steam inlet channels / V, connecting them with the corresponding steam outlets. Due to this, when a steam locomotive moves without steam, gases that are compressed in one cavity of a steam cylinder can freely be distilled into another cavity through steam distribution channels and steam outlets and, therefore, shifted, as indicated in FIG. 2, the spool will replace the bypass.
