PATENT OFFICE.

The invention relates to a device for the automatic heating of Water and for moving the heated water through a pipe system with the aid of steam according to the type of patent 154418 . protected device, but differs from this in that the heating and the expulsion of the heated water takes place in two separate rooms. this

ίο has the advantage that the warming is done by the expulsion is not disturbed in any way, including during expulsion Progress continues, while with the older device the supply of the material to be heated Water must be interrupted for the time of expulsion.

The device can be used for heating apartments, for heating water for Laundries or other household purposes, for heating the feed water for Steam boiler or the like. Be used.

The device is either steam

of low voltage to heat the water and steam of higher voltage used to circulate it, or steam for both purposes is made from it Tube removed; but then a pressure reducing valve must be installed in the pipe leading to the boiler room be switched on.

The device makes it possible to keep the water moving continuously without

that its heating is interrupted; in addition, one can see the information communicated to the water Regulate heat independently of the flow, and finally the pressure and the flow in the circulation pipe become constant and the flow is not affected by the heating.

Two exemplary embodiments of the subject matter of the invention are shown in the drawing. The upper container a, the boiler room, is used to heat the water. It is fed through the pipe j, which can be shut off by the tap k , slightly pressurized steam. A water tank / is arranged above the boiler room, from which the water enters the boiler room α through the pipe system c and the valve d. Here it is divided into fine rays by perforated plates h and ζ. A pipe not shown in the drawing leads from the upper part of the boiler room to the riser pipe %. This pipe is provided with a non-return valve and has the purpose of removing the air that remains in the boiler room and preventing the accumulation of steam in it.

When the boiler room is filled with water up to a certain height, the water lifts a float e and closes the valve d completely or partially with the help of the lever / and the rod g, see above

Claims (2)

that the water either does not enter the boiler room or only enters the boiler room at a slow rate. The heated water flows through a check valve into the ejector /. When this is filled to a certain height with water, the water lifts the float ί in the ejector so far that it hits against the stop u and opens the high-pressure steam valve ρ by means of the lever w. As can be seen, this is designed as a double seat valve. From its lower seat a pipe q, the purpose of which will be explained later, leads to the low pressure steam pipe j. This pipe is now closed. From the tube χ then high-pressure steam enters the ejector one, the check valve in and drives the heated water through a check valve s in the lower part of the ejector and the pipe \ in the container /. Should in the event that the float t settle, a second float can be provided 3, wherein the valve closes r independently of the float t, so that the blowing is avoided by high-pressure steam into the pipe \. As the water level in the ejector drops, the float t moves downwards, hits the stop 2, closes the high-pressure steam pipe χ with the lever w and valve ρ and at the same time connects the ejector with the pipe q, through which the steam remaining in the ejector is in flows through the boiler room, in which it helps to heat the incoming water. The pressure between the heating chamber and the ejector is q through the tube balanced, the water can again through the check valve in flow into the ejector, and the process described above is repeated. Fig. 2 shows an embodiment of the device which differs from the first only in that the containers α and / are not arranged one above the other, but side by side. The reference numbers are the same. The device is shown here with the boiler room full. The valve is d accordingly closed, "can occur while in the ejector valve ρ high pressure steam and the heated water through the tube expels \. The boiler room α as well as the ejector I can be fed by steam from the same steam pipe. In the pipe leading to the boiler room, a pressure reducing valve is switched on, which reduces the pressure of the steam intended for the boiler room accordingly. The pressure in the boiler room can be higher or lower than atmospheric pressure. The pressure reducing valve can be used to regulate the amount of heat required to heat the water. For safe operation of the apparatus, it is a condition that the vapor pressure in the boiler must not prevent the inflow of water in it and must have the high pressure steam in the ejector sufficient voltage to maintain the pressure of the water in the tube to overcome%. Godfather nt-A ν Proverbs: I. Apparatus for heating water and for moving the heated water in a pipe system with the aid of steam in the manner of the device protected by patent 1.54418, characterized in that the heating space (a) for heating and the ejector (I) for expelling the heated water through a check valve (m) are separated from each other, with a float in the boiler room (a) for regulating the flow of water into the boiler room and a float (t) in the ejector for regulating the steam supply to the ejector. 2. In the device according to claim ι a device for pressure equalization between the low-pressure steam line and the expeller (I), consisting of a tube (q) with a valve (p) controlled by the float (t). 1 sheet of drawings.
