SU13788A1 - Switch valve for metering liquids of instruments with several paired measuring vessels - Google Patents

Description

In the proposed switching valve, for measuring liquid and devices with several pair of measuring vessels, a cylindrical plug with a central supply channel having two radial channels connected to it is used. The stopper can be relocated in the axial direction by means of a spring and a lever, whereby the annular recesses on its surface communicate one of the loose vessels with the liquid supply pipe and the other with the feed channel.

In FIG. 1 schematically depicts a side view of the instrument supplied by the proposed crane, the latter being shown in section; FIG. 2-horizontal section of it with a different position of the tube; fpg 3-top view of the crane.

The plug D is fitted with a central channel J with two radial branches K, has annular recesses B and B on the surface.

At the position indicated in FIG. 1, the fluid flowing through pipe B goes

through pipe B into the recess, from where it passes through pipe G, into the measuring vessel j. At the same time, the latter’s paired vessel (not shown in the drawing) is connected through pipe D and channel K downwards. If you press downwards on the lever P of the plug L, then the drop L is connected to the recess 5, and the vessel F will be blocked; the recess B will now connect tube C to tube T, as a result of which the second measuring device will be filled, etc. To return the plug ZT to the upper position, spring J. serves.

To communicate the crane with another vessel of vessels G (Fig. 2) or G. The cork is turned using the handle A, and the arrow is equipped with a scale L (not shown) for correct installation.

The subject of the patent.

A switching valve for liquid-measuring devices with several measuring vessels, characterized by the use of the spring G and the lever P of the cylindrical n |) arm .77,

equipped with a central feed channel K and two communicating with it radial channels IC, on the surface of which tube there are annular recesses B and j5j, through which

at any position of the plug, one of the tubes T, or T of each pair F, M and F, of the measuring vessels communicates with the liquid supply tube B, and the other T. T with the above channel K.
