SU13624A1 - Instrument for automatic metering of liquid using two alternate measuring vessels - Google Patents

Description

The invention relates to an instrument for automatically measuring a liquid by means of two successively measuring vessels connected to each other and to supply and flow pipelines by means of a common distribution valve. In the proposed device, the tap of the crane is equipped with three channels, the openings of which are located in one plane, normal to the axis of the crane, the latter being equipped with two connections to the supply pipeline.

In FIG. 1 shows a schematic section of the device; FIG. 2 vertical section of the measuring vessel; FIG. 3 shows the relative position of the parts of the device.

In the plug of the distribution valve 1), equipped with two tubes 7 and 8 for connecting to the supply line C and tubes 9 and 10 connecting it to the measuring vessels N and M, there are three channels 1 - 2, 3 - 4 and 5 - 6 whose openings are located in one plane, normal to the axis of the park.

At position a of the tap of the crane D (Fig. 1), the channel 3-4 connects the tubes 7 9 between them, the irregular flow than the liquid from the supply pipe C enters the vessel N, while the channel 1-2 communicates the tube 10 with the flow pipe H, As a result, vessel M. is emptied. Turning the nrobka to position b, vessel N is communicated through tube 9 and channel 5-6 with flow pipe H, and vessel M through tube 10, channel 3-4 and tube 8 with feed pipe pipeline c. At the same time, the vessel M is filled and the vessel N is emptied. For a more uniform filling and emptying, the vessels M and N are equipped with float valves K (Fig. 2).

The subject of the patent.

A device for automatic metering of the core bridge with two successive measuring vessels connected with each other and with the feed and supply pipelines through a common distribution valve, characterized in that the valve plug is equipped with three channels 1-2, 3-4 and 5-6, with than only one of them overlaps the other two, the openings of which channels are located in the same plane normal to the axis of the crane equipped with two connections to the supply pipeline c.
