Description

B patent No. 13162, describes an apparatus for automatic feeding of steam boilers, in which there is a spool chamber equipped with two spools located one above the other for steam and for water from the injector set in motion by the stem of the float. In the proposed modification of this apparatus, instead of two spools located one above the other, there are two zodotniki placed on the sides of the swivel chamber and interconnected with a spring-mounted cross member connected to a rod carrying a disk connected to it and connected to a float.

The drawing shows a longitudinal section of a modified apparatus.

In the round case of the float 1, mounted by the Ring lug 2 on the stand 3, is placed; n the float 4, provided inside with a thrust column 5, preventing deformation of the walls of this float. The lid 6, bolted to the chamber 1, has projections on both sides, to which the injector 7 and the valve 8 of the chamber are attached;

The sides have a round protrusion 9 with thin walls entering the chamber 1 between the walls of the latter and the float 4 and intended to isolate the latter from the strong pressure of steam entering the side tube 10 of the body of the chamber 1.

On the lid 6, a circular spool chamber 11 is fastened on the outside, which has thick walls on both sides with channels for steam and water. The chamber 11 is closed by a bolted throat 13, fitted with spool nipples 14 and a tap 15, which serves to release excess steam from the chamber. From the side of the spool 12, the walls have vertical projections in the form of dovetail tails, which enter the respective slots of the spools 12, moving along them up and down and are equipped with semicircular channels 16, as well as slots 1 / for the cross member 18 connecting the spools 12, tightly pressed springs 19 of the cross member 18. Last connected by means of a nut with a rod 20, carrying a disk 21 rigidly connected with it and connected by a chain with a float 4.

The coasters 22 spools 12 are reinforced to the lid 6, below which the latter cannot be lowered. The injector chamber 7, connected by pipelines with the spool chamber 11, is round-shaped, thinned in the middle, with holes for water and water vapor from the lower and upper ends, respectively, with a side pipeline ending in a thinned tube in chamber 7 couple.

The spherical valve chamber 8, consisting of two bolted halves and communicating with the pipelines with the spool chamber 11, has a valve inside with a spring covering the tapered bore at the moment when the water enters the boiler. The apparatus is installed at the side of the boiler at the desired water level in it. When water is lost "in the boiler and in the float chamber 1 communicating with it, the float 4 lowers9 together with the stem 20, moving the spools 12 to the lower extreme position, after which 11 pairs entered the spool chamber through it and the spool channels will rush into the injection chamber 7, where, the exit from the narrow tube goes upwards / sucks the water of the lower pipe and goes along with it through the spool chamber 11 and the architect 1 12 canals to the valve chamber 8, opening the valve and direction Subscribe to the boiler.,

When the water rises in the boiler, the latter raises the float 4 chambers 1 together with the rod 20 and spools 12 and closes the channels until the next loss: water in the boiler.

The subject of the patent.

A modification of the apparatus described in Patent No. 13162, characterized in that, instead of two spools located one above the other, two spools 12 are used, placed on the sides of the spool chamber and connected to each other with a spring 18 equipped with springs 19, connected in turn with a rod 20 carrying a disk 21 rigidly connected with it and connected to the float 4 by a chain.
