SU12466A1 - Lubrication switch for stop when driving a steam locomotive without a pair of spools - Google Patents

Description

In the present invention, a lubricant switch for gold-bearing locomotives stopping when driving without steam, is supplied with a distribution tube with channels, which, when driving with open pressure regulation, turns the steam to pass the spool to the spools, and when the regulator is closed, the spring turns to lubricate back with grease pump.

In FIG. 1 shows a longitudinal section of the switch; FIG. 2-section on lipia 1 - 1 FIG. 1st; FIG. 3 is a top view; fmg 4 is a top view of a distribution plug with a reinforced padded carrier; FIG. 5 is an inside view of the side surface of the housing in an expanded view showing the location of the openings of the nozzles; FIG. 6 is a view of the lower part of the rod; FIG. 7 - end view; FIG. 8 is a side view of the piston; FIG. 9 is a side view of the components of the piston; FIG. 10 is a top view of the housing with fittings at the position of the distribution plug corresponding to the lubrication pass ъ gold-nickel figs. 11 - also at the position of the plug corresponding to the direction of lubrication in the lubrication pump.

The switch consists of four main parts (Fig. 1, 2 and 3): housing A, steam cylinder with housing cover B, plug B and piston with rod g.

Case A has the shape of a cylinder and around its circumference there are ten pairs of diametrically opposite fittings arranged in different levels: 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10, of which 1, 2, 3 , 4 serve as input for lubrication and are connected to the Frndman oil, the four fittings 6, 7, 8 and 9 opposite to them are output and communicate with spools, fitting 10 serves to drain the lubricant back into the oil, and through fitting 5 heating device.

Inside the casing (Fig. 2) there is a Trench for inserting the distribution plug and cylindrical for its tail. An annular coping protrusion 11 centers the lid B. For heating in the lower part of the body, there is an annular recess 11, which is closed at the bottom by a ring and communicates with a number of vertical channels not drilled in wall thickness between fittings; .13. . Channel 14 (FIG. 11) is reported as being supplied to CPU 5 ;,

for removal of the heating steam serves fitting 15 (Fig. 2). At the bottom, the body ends with a round tail, with which the device is attached to a steam locomotive.

The steam cylinder, which is integral with the lid B (Fig. 2 and 3), is closed by the lid 16 (Fig. I and 3), screwed in with four bolts. A fitting 17 serves to feed the cylinder into the cylinder from the steam tube. The opposite part of the cylinder passes into the tube for seeding the rod, which is screwed inside with the end into which the coupling 18, which adjusts the spring force of the mud and is fitted with a locknut 19.

The NDR was drilled by means of a lid connected to housing A with four screws 21, centered around an annular protrusion 11. In the center. the cover has a screw 22 (fig. 2 and h) with a lock nut preventing the cork from lifting. A piston Pr, detachable in three parts, is put on the cone of the stem and secured by two nuts 23.

The stem G in length has two different diameters; In the part of the rod with a large diameter, a notch 24 is arranged, covering the finger 29 of the carrier 28 (Fig. 1), and the return squad Lzh is put on the part with a smaller diameter. The slot 25 at the end of the rod is puddled to place the wedge 27 when the instrument is muffled.

To retract the stem G, a flywheel 26 is mounted on its end, to which a wedge 27 is suspended from a chain.

The distribution plug B is tightly rubbed into the corresponding recess of housing A. On its upper surface, two screws 30 are fastened. The carrier 28 is fastened with a finger 29, which serves to turn the plug with the -G stem.

At the nozzle 31 of the cylinder (Figs. 1 and 3), an oil is placed so that the lubricant opening is located behind the first piston ring when the piston is in the working position with steam, in order to avoid blowing lubricant out of the oil with steam.

Hole 32 serves to drain the steam leaking through the rings, and hole 33

eliminates air compression under plug B during heating and removes lubricant that has been used on the plug.

Fittings 1, 2, 3, and 4 and 6, 7, 8, and 9 have through holes that continue in the plug in a position that corresponds to the operation of steam on the spools (Fig. 10); in the position of the tube without steam (Fig. 11), fittings 1,2, 3 and 4 are connected with fitting 10 by converging channels into a common opening.

The action of the device is as follows.

When opening a pair of piston Pr, pushing back, cutout 24 of the rod 7 turns the finger 29 of the carrier 28 and distributes the plug B and places the holes in the fittings in the through position. The return spring PZ is compressed and the lubricant from the oil enters the spools. When closing -pair by the action of the spring Pzh, piston Pr with rod 7 is returned back, turning the plug B. The through holes are then separated and channels are inserted against the inlet nozzles 1, 2, 3, 4, diverting grease back into the nozzle 10.

The movement of the piston Pr is limited, on the one hand, by the cover 16 of the cylinder, on which it rests against the nut 23, on the other hand by the annular ledge 20.

For the plug of the device, the rod 7 is pulled off behind the mohovich 28 into the working position and jammed through the groove 25 with a wedge 27.

All the channels, both in the traffic jam and in the housing, are slightly broken at the junctions. On all non-working surfaces of the plug, grooves are cut out in a staggered order for fatigue.

The subject of the patent.

A lubricant switch for stopping when a locomotive rides without steam spools, characterized by the use of a distribution plug B fitted with channels Кз (fig. 1Q) v Кн (fig. 11) turned when driving with an open regulator - pressure and steam on the piston Pr for passing the lubricant Kavalam Ks to the spools, and when the regulator is turned in the opposite direction by the Pzh spring, which can be adjusted, it is used to direct the lubricant through the channels 1, 2, 3, 4 (Fig. 11) back through the E and channel 10 to the lubricating pump.
