Description

This invention relates to the further improvement of already known steam separator mechanisms for operating steam engines, for a tandem pump, using only one spool, one spaced one cTotpofly impact piston M, and the other for steam, in relation to (beat and a simplified design. To this end, to ensure the output of the spool from the middle position, by feeding naipa into the chamber ia (the driver (by one, in the proposed vapor-transfer device, the distance between the channel) The camera communicates between the upper and middle discs with a part of the cylinder and the piston hell and under the piston, which is smaller than the distance between the spool discs mentioned above. to the compression chamber of the working machine "s. Thus: the spool being moved: in the | bottom side of the piston of the steam cylinder, in the other direction it is moved by the compressible same piston, while moving it to

lower dead position, m ay steam. At the same time, moving the spool does not cause a decrease in pressure in the upper spool, as it is, as already said, with the lower part of the steam cylinder, where, before displacing the spool down, there was crushed steam, and where, after shifting the spool down, fresh steam arrives. The possibility of obtaining compressed m ate steam: is achieved by the fact that the lower part of the cylinder is connected to the spool chambers by two independent channels — one for the inlet of the new barrel under the piston, the other: for the discharge of that pair into the atmosphere (or a low-pressure cylinder). At the same time, the opening of the last kiaal is located above the bottom surface of the porsche at its extreme lower position.

In FIG. 1 shows a diagram of a steam-separation device for tandem-coicy; FIG. 2 - application to compound pump.

A cylindrical spool 1 for a tandem pump is placed in a detachable carriage of a steam cylinder 2 and

It consists of three discs 3, 4 and 5. It is equipped with a shank b, which serves to deliver the zipper to the piston 16 in the upper position. The chamber drives 3, 4 half fresh steam from the boiler and through openings 7, 8 (from the position of the spool) from the spool is reported irn POS: M: Protect channel 7, 8 with a piece of Chi, or 1 over the barrel Porsch & m The chamber between the disks 4, 5 communicates, on the one hand, with the atmosphere, on the other, through the openings 9 and 10 and the corresponding channels, also with the lower and upper parts of the steam generator. Hole 12 in the lower part of the cilium, to which the channel is adjacent, communicating through OTiBepcTHe 9 with the atmosphere, is expanded, as already mentioned, above the bottom: its piston surface is in its lowest position.

In kZmera above the top of the disk 3 there is a hole 11, connected by a channel 13 with a hole in the bottom of the cylinder. A hole is arranged in the chamber below the lower disk, which connects this chamber with the atmosphere.

The distance between channels 7 and 8 is such that they cannot be simultaneously closed. If channel 7 is open at start-up and channel 8 is closed, then steam from the boiler enters the space above the piston 16. If channel 8 is open and channel 7 is closed, then steam enters below oorsch 16. Finally, if both channels 7 and 8 are open , then through the channel 13 through the opening 11 the steam enters the chamber above the disk-3 and moves the spool downwards, and the channel 7 is not closed.

The effect of the steam-dividing device is as follows. If the spool 1 is in the “i-position”, the steam from the boiler through the channels 8 and 15 falls under the piston 16 nd moves it upwards. Mated steam (ILi air) through the holes 14 and 10 from the upper part of the cylinder goes IB atmosphere, and from 1x1 ping 9 closed disc KOMi 4. The spool position is ensured by the fact that

the disc contains fresh steam that enters there through the opening 11 through channel 13, and sing, the hatchway has a PSL: atm0: spherical pressure.

When the rim 16 comes up to the upper position, it strikes the shank 6 and moves the spool to the upper position, with the steam from the chamber above the disk 3 being displaced to the lower part of the cylinder 2. The 1 m disk 3 communicates with the atmosphere (through hole II , channel 13, as well as through the channel connecting the holes: 12, 9) earlier than steam through channels 7, 14 begins to flow into the upper part of the cylinder. Therefore, for some reason, the e-gold after the gold piston does not inch before its piston, its upper position, it moves into this position — the vapor pressure on the x-island 6.

The cloud then the piston 16, lowering the valve, will block the opening 12, which is under the piston. The steam begins to compress and this compressed steam (or air at start-up) presses and - and the upper disk 3 of the spool. Since the pressure under parish does not: m can increase to the pressure of the fresh steam by the piston: k because the horizontal section of the disk 3 is greater than the horizontal section of the shank 6, the movement of the zo-lotter downwards ensures. After the zolatik is moved down the verx part of the cylinder 2 through the openings 14, 10 is in communication with the atmosphere, and fresh steam enters the lower part through the openings 8, 15. The constancy of the position of the spool is ensured by the fact that vapor pressure is above the spool and atmospher pressure under the spool.

The unstressed lowering of the spool is achieved on the one hand by small ones, m di am: the opening of the hole connecting the LOWER chamber with the atmosphere, on the other hand the gradual increase in the distance in the upper chamber of the spool. When climbing up, the gift of the spool is removed, due to the presence of a paravite pillow.

When applying and offering a compaud-aooos (Fig. 2), another disk 17 is required to the described ipKdaBiiTb slide valve to form a camera that serves to communicate the low-pressure cilidar with atmosphere through holes 11 and 18 or 19. Naip from c The high pressure niad 22 enters the low pressure cylinder 23 through the chamber between the disks 4 and 5 and through the holes 20 or 21.

The subject matter of the invention.

Claims (2)

1. A steam distribution device for “steam engines” using only one spool moving in one direction of the piston, and in the other - steam, about and l. This is due to the fact that, for the purpose of obiChepheni1, through the flow of steam into the national chamber, through the channel connected to the space under the piston, in the case of a spool stop, in the middle position, the distance between the channels 7 and 8 is less than between the discs 3 and 4 spool. 2. Device pop. 1, characterized in that the channel 13 for supplying steam to the chamber above the golden chain is connected to the compression chamber of the working cylinder of the machine.
