Description

In the proposed observation device, a float is placed inside the boiler in the boiler water level, connected to one of two communicating vessels containing difficultly boiling liquid. Another vessel is brought out, and according to the level of liquid in it, depending on the fluctuations of the vessel placed in the boiler, the level of water in the latter is determined.

The bottom of the isolation from the environment of the boiler vessel is enclosed in a cap, which can also serve as a float, the cavity of which is communicated with the atmosphere through a tube.

In the schematic drawing of FIG. 1 is a side view of a device for monitoring the level of water in a boiler; FIG. 2 is the same in a different form of implementation; FIG. 3 - the same, with an insulating-1m cap; FIG. 4 - the same with a cap serving as a float; FIG. 5 - dp signaling device for distance level indications.

With a float placed on a tube (Fig. 1) or floating freely 1M (Fig. 2) in a boiler, is connected a cylindrical vessel connected via tubes 3 and 2 passing through the bottom of the boiler with a glass vessel 4 discharged to the outside. with a funnel-shaped cap 5. The top opening of the cap 5 is closed

a stopper made of porous material, for example cotton wool, felt, etc., for communication with the atmosphere. Through the funnel 6 of the upper tube 3, the vessels 1 v (4 are partially filled with difficultly boiling liquid. When the water level in the boiler changes, the float with vessel 1 rises or falls, and depending on the change in the level of liquid in the vessel 4, water level is determined.

Yes, the possibility of observing the level of water in high-placed boilers introduces a device already known, consisting of a tube 7 connected to the tube 2 and equipped with a V-shaped tube 8 at the bottom, filled with the arch. The oscillations of the column L of mercury, depending on the change in the value of H, will be proportional to the change in the water level in the boiler. A float 9 can be placed in the expanded part of the tube 8 (г., 5), connected with the arrow 10 sliding along the plate // included in the battery circuit / J; When the arrow / i5c brush is connected by one of the contacts / 2, the circuit is closed and a sound or light alarm is triggered to indicate a corresponding level change.

In the embodiment of the device shown in FIG. 3, for isolation from
