Description

The proposed apparatus for the automatic feeding of steam boilers aims to automatically maintain the water level in the steam boiler at a desired constant height.

The apparatus is shown in vertical section in the schematic drawing and is arranged as follows: the bottom of the float chamber A is provided with a pipe 8 connected to the water space of the boiler and a protrusion 1 with several openings; A rod 9 is freely inserted into the sleeve of the protrusion 1, passing through the conical opening expanding upwards in the lid 10 of chamber A, over which hole the rod 9 has a corresponding conical fit. On the rod 9, a float 2 is loosely worn, supporting loads 11, each of which is fixed at the end, e of the lever 12 suspended from the lid 10; the free ends of the levers 12 enter the slots of the ring 13 fixed on the rod 9. To the wall of the float chamber is attached a Z4 nozzle connected to the steam space of the boiler and a control valve 15. On the lid 10 a spool chamber D is strengthened in the thickened wall 5 of which there are several through channels; the two upper Oj and 0, jraK are the same as the two lower fj and 0 are flushed and communicate with each other using the pushed

springs 4 spools 5, of which the lower one is connected to the rod 9. Between themselves 30.10TNIKI-- are connected by a rod 15, passed through the guide sleeve 16. Channels O serve as outlet, and channels closed by mas.1enkami M are for lubricating the surface on which the slide slides when moving. Channel 0 is connected by pipe 1 to the steam space of the boiler; the channel Od-pipe 18 with the internal cone-tube of the injector, communicating from below with the reservoir; channel by pipe 19 with an external injector pipe equipped with a control valve 20, and channel 0 through the check valve G above the float chamber with the boiler water space. The injector, as well as the valve G, is attached to the float chamber. Valve valve G is a tapered disk S1, supported by the bottom spring 33 and the opening OPEN only in the direction from top to bottom.

Height Attaching the device to the boiler is chosen so that water, being at the desired level in the boiler, flows through pipe 8 into the float chamber and raises the float S to such a height that the loads 11 lying on it hold levers 13 rod 9 in position at which spools 5

overlapping channels 0, 0, 0. and 04. When the water level is lowered, the level in the float chamber will decrease accordingly in the boiler, as a result of which float 2 with weights 11 lowers, moving upward through rod 9 the spools 5 to such a position that channel C reported by channel O, channel O, -c 64; then the steam coming from the boiler through pipe 17, the passage through pipe 18 into the injector, will suck in the water, which through pipe 19, channels 0 and 0 through valve G enters the boiler. An increase in the water level in the boiler will cause the float to rise, S and, accordingly, lowering the spools 5 to it, and when the boiler is filled to the desired level, the latter do not rest so much that they cover channels O ,, n, 0 S 0 and thus stop the water supply to the boiler . With the cessation of the pressure of the water supplied to the boiler, the disc 21 of the valve G under the action of the spring S8 closes the passage, thereby preventing the back flow of water from the boiler. The taps 16 and 80, which are opened as needed, are designed to control the action of water.

The subject of the patent.

An apparatus for automatic feeding of steam boilers characterized by the use of float chamber A, spool chamber B and injector B, of which the float chamber is located at the height of the water level in the boiler, attached to the boiler using water and steam nozzles and includes a float 8 with some free stroke, the spool chamber is equipped with two for steam and for water from the injector-spool 5, produced in movement by the float rod and exhaust channels O, and the injector is connected to the float chamber and connected to the ash camera-twinned using. corresponding tubes, in which apparatus the lowering of the smelting of the zolotnbuk becomes in a position in which steam from the boiler is supplied to the injector for its operation, and water from the injector enters the boiler through the check valve G, and when the float rises at which the injector stops working.
