Description

Central distribution device for liquid fuel to heating devices in apartment blocks The invention relates to a central distribution device for liquid Fuel to heating devices in apartment blocks, the distribution device being a central deep-lying oil container and a pump for sucking in the liquid fuel from the oil container and pushing it up through one that extends to the upper floor Pressure line and at least one downpipe connected to the pressure line has, of the branch lines at the level of those in the individual floors Branch off heating devices.

The object of the invention is to remove the downpipes from central distribution facilities to keep the above-mentioned type depressurized in order to counter the risk of fire. These is at pressurized case and subsequent branch lines with their many Connection points are given to a greater extent by leaking connections. This also applies to a previously known system with an elevated tank. In their drainage lines there is an overpressure determined by the position of the elevated tank at all points 'of the fuel.

In contrast, according to the invention to solve the above-explained Task provided that the pressure line via a cross-sectional constriction essentially vertical downpipe is connected and the liquid Fuel metering devices arranged in a cascade among one another in the downpipe can be fed to the downpipe with a larger passage cross-section than the cross-sectional constriction is.

This leaves all downpipes that occur multiple times in a block of flats and all the numerous storey branch lines branching off from it depressurized. Every Downpipe forms in the intended placement of the metering devices in it at the same time the overflow and return lines.

In the drawing, the subject matter of the invention is based on exemplary embodiments shown. In it, F i g. 1 shows a diagram of the line network, FIG. 2 one of the Metering devices which are arranged in the downpipes, FIG. 3 a section after the line 3-3 of FIG. 2, fig. 4 another embodiment of a metering device, F i g. 5 the connection of the central pressure line to a vertical downpipe.

The liquid fuel (oil) is pressed from a central, lower-lying oil container 1 by the pump 2 into the pressure line 3, 4. In each case via a cross-sectional constriction 5, the oil flows from this pressure line into downpipes 6, to which distribution lines 7 are connected in the various floors (see FIGS. 1, 2 and 4). The excess oil not removed from the distribution lines 7 is returned to the oil container 1 through an overflow and return line 8.

In Fig. 2, the metering device 11 has a trough-shaped top open container with its circular end wall facing the distribution line 7 12 provided overflow opening 12a to the distribution line 7. This metering device is designed as a bridge part with a passage cross-section13 and one off a pipe section existing pin 15 in a distribution line 7 opposite Tube 7a introduced with sealing cap 16 and placed therein on a circular plate 14 rotatable in order to shut off the supply to the distribution line 7 by turning the container around. The passage cross section 13, designed as a bridge part, allows a passage for from Container free of unabsorbed fuel. This reaches the next lower, of the metering devices 11 arranged one below the other in a cascade-like manner the metering device 11 provided, can be screwed onto an external thread of the tube 7a Sealing cap 16 and a sealing ring 17 is sealed, the sealing cap 16 also serves as an actuation button. By the use of Sealing rings 17 of different thicknesses, it is possible, did 2uriiel3'vöitichtung 11 horizontally to adjust, whereby the ratio of the amount of oil, which on the container on the one hand and on the other hand, the passage cross section 13 can be controlled.

In Fig. 4 dihe Ziimeßvbrrichtung 19 is drawn, which can also serve as a level controller for the ah the distribution lines 7 connected heating equipment. If this ambient device 19 is used, special level regulators can be omitted on the heating devices.

The oil flows mainly on the walls of a fall 6 , fills the space of the inflow device 19 up to the passage cross section 20 and flows further downwards in it, on the other side of the pipe 13. A level I is established in the distribution line 7.

Such a level position has for an oil distribution "system at deffi the Bieimstöffkösten are turned over, special meaning. Consumer; the one want an exact calculation, the connection of a quantity counting fillet can beänti: ägeii, however, a certain supply pressure is generally required for its use is.

By sealing the passage cross-sections 20, for. B. by means of a pen. The like., And putting on an open top, in 1 'i g. 4, the pipe drawn in dashed lines vhid the level I raised to the level 11 , whereby the required supply pressure can be obtained.
