SU19412A1 - Tool for adjusting the pressing of self-springing piston rings - Google Patents

Description

When steam is let through by piston cranes for repair, they have to remove the front cylinder cover, etc., and during the shooting of the ring, there are often cases of breakage. In order to avoid ring breakage and to adjust them without disassembling the cylinder, the proposed C1-torsion 5gI uses a rod that is moved and cut along the ijiTOica central channel with a conically turned end on which rods located in the radial channels of the piston and fitted with pistons at the outer ends are placed under pistons. rings.

In FIG. 1 shows a vertical section through a piston with proposed devices; FIG. 2 is a front view with a partial section,

In the piston rod, a central channel is threaded with a cut-in end, into which a rod b fixed with a lock nut fj is screwed, equipped with a conically turned end, against which the rods located in the radial canal of the piston are equipped with hollows (I, placed in the corresponding angle bars) under the piston rings, e. The rods are pre-screwed into the heads d, and then riveted. To seal the pistons, release the lock nut d and a key that is put on the square part of the cylinder /, screw it into the rod, m conical end, respectively, pushes the rods and heads

which

adjusts the pressing of the piston rings e.

The subject of the patent.

A device for adjusting the pressing of piston self-springing rings, characterized by the use of rods a in the radial channels of the piston, stasbeygenic at the outer ends of the heads /, placed under the rings e and upright with the ends of the rod located in the central channel of the piston rod and the thicker bridging of the latter on the cut / and held in certain positions with the help of KOHTJ nuts fi.
