Description

For measuring the liquid in the distribution network, there is a whole range of double action meters with fixtures for locking taps during emptying and filling, but all of them suffer from some or other disadvantages. Some of them do not meet the requirements of sanitary inspection due to the presence inside the measuring instruments of devices for controlling the locking and release of valves that are exposed to oxidation, contamination and difficult to wash and clean. Others do not justify themselves for reasons of inaccurate measuring or deviations from the amount of liquid set for measuring. The idea of the inventors is directed to the creation of such a liquid meter, which would measure out with greater accuracy, satisfy the requirements of hygiene, prevent the possibility of abuse, and finally, take into account the amount of liquid passed through the meter. According to the invention, a device of the type described is proposed, consisting of a pair of alternately operating measuring vessels with a stop valve that is locked during the filling and emptying period and a container regulating capacity of measuring vessels, the distinctive feature of which is from the already known liquid meters that

To solve the problem of accurate metering, besides the tube in the meter lid, which communicates with the supply tank, and intended to stop the flow of liquid into the measuring vessel over a certain amount, a second tube of small diameter moved in the vertical direction inside the first tube is used to establish a more accurate metering.

FIG. 1 of the drawing shows the appearance of the device with a partial section; FIG. 2 shows the device of the crane locking device in side view and FIG. A 3-mechanism for activating a meter that records the amount of fluid passing through the instrument.

An instrument for a measured spill of liquids is a type of backpressure instrument. It consists of a pair of hermetically sealed measuring vessels 7 and 2, which are filled through an intermediate tank 77. The constant level of the liquid in this tank is maintained by means of a well-known float valve installed at the end of the supply pipe entering this tank. The sequential filling and emptying of the measuring vessels / and 2 is controlled by a multi-way distribution valve 75, the body of this crane communicates with the measuring vessels through cranked tubes 18 fixed to their bottoms 18. Turning the plug of the distribution valve 13 is made by the handle 19 protruding partially from the casing 20 blocking access to the crane, the counter and the fixture that secures the crane. The lids of the 3 measuring vessels have the tubes 5 passed through their center. These tubes communicate the measuring vessels 7 and 2 with the supply tank 77. On the inner side of the lid 3 there are tubes 4 installed in them that are concentric with the tubes 5. These tubes and 5 are designed to to leave the exact amount of liquid, and the tube 4 solves the problem of coarse Stmer, and the tube 5 refines this dimension by moving it in a vertical direction and, consequently, by changing the time at which the liquid clogged. The difference in the diameters of tubes 4 and 5 makes it possible to establish the exact amount of liquid required for dispensing. A meter 75 is mounted in a housing 20 enclosing the crane, and each time the latter is switched, it is driven by a cam 14 mounted on the valve plug.

The stopping of the crane during the emptying of the measuring vessels is reached by the bolt 11 entering the sockets 12 on the stopper of the crane 13. The bolt dropping into the sockets of the crane stopper occurs when the valve 10 is turned by the liquid flowing out of the measuring vessel. The valve 10, turning on the hinge, closes the opening 9 of the drain pipe 6 and with its shoulder moves the bolt in the vertical direction. The liquid, pouring out of the nozzle b, enters the box 7 and from the latter through the nozzle 8 into the reception dish. The plug 75 is extended by a rod 16, to which the handle 19 and the cam 14 are attached.

The device works like this. By switching the valve, the filling of one of the measuring vessels begins. The liquid, reaching the tube 4 and closing it, forms a liquid sealing, preventing further air from the measuring vessel through the tube 5. The Rdnanr part of the liquid will enter

into the tube 4. To regulate this amount of fluid that has entered the tube, a second tube 5 of smaller diameter is used, producing a second liquid closure and setting a precise metering. After filling, the valve switches in the opposite direction, the filled measuring device begins to be emptied, and the second one at this time is filled. The fluid flowing out of the nozzle b will, by its weight, deflect the butterfly valve 10 and the latter will insert the bolt 11 into the socket 72 of the tap of the crane, which means that the valve locks for a while until the measuring vessel is completely free of liquid. In the following, the process will be repeated in the same order.

The subject matter of the invention.

Claims (3)

1. A device for measured spill of liquids, consisting of a pair of measuring vessels alternately filled and emptied when switching a multi-way valve, which is locked during the emptying time of one or another measuring vessel, using displaceable 3 vertical direction tubes for regulating the amount of liquid subject to tempering, communicating with the supply tank, and a counter for registering the amount of liquid passed through the device, characterized in that, in order to achieve an accurate measurement of the liquid with Clauses 7, 2, covers 5 of the latter are equipped with a pair of concentric tubes 4 v (5, the first of which is fixed and has a diameter greater than the diameter of the second, serves to approximate the amount of liquid to the spill, the second tube 5 is designed to precisely adjust this number by moving vertically inside the tube 4. 2.
