SU11465A1 - Automatic feed regulator for steam boilers - Google Patents

Description

In the proposed automatic regulator p {(for steam boilers, a float valve is used

for steam and a piston valve in the feed line leading to the boiler.

 Figure 1 is a schematic vertical sectional view of the controller.

Steam and water spaces of the boiler are communicated through the nozzles g, g with the chamber, into the guides, about which the float n moves, fitted with a valve b on the tail of the upper rod, chamber d is communicated through the pipe t with the cylinder l equipped with a piston that sits on the same rod with the valve KIS piston in the cylinder l /.

As long as the water level in the boiler is high enough, the float n is in the upper position and the shutter b closes the opening of the pipe m. When the water level in the boiler drops, the float lowers, and the shutter b opens a pair of access to the cylinder l. Under the influence of steam, the piston and, together with the valve, goes to the right (see / drawing) and the feed water flows through the pipeline, p into the boiler.

When the water level in the boiler is aAc-4-1S5f is of normal size, the shutter grests steam access to the barrel, after which the steam in the last steam is condensed, and the condensate is drained through a drain pipe, equipped with a faucet. Under pressure from the supply line, nopnieHb e goes to the left, closing the valve to access the water in the boiler.

Valve k can be replaced with a cylindrical or flat valve.

I.,

The subject of the patent.

An automatic power regulator for steam boilers, characterized by the use of a float valve for steam and a piston valve on a feed line to the boiler, of which the first organ consists of a float and a slide in the rails o, o, and is provided with stopping the steam from the boiler to the second stop valve at a sufficiently high position of the water level in the boiler, and the second body is a valve k in the pressure feed line connected by a rod e down piston a and in , of which the hole under the influence of the vapor pressure that passed through the first stop valve

the body opens water to the boiler, and the piston in, under pressure from the supply line, closes the water to the boiler when the first piston a stops steam.
