Устройство работает следующим обра зом. ' ⁴ The device operates as follows. ' ⁴

Под действием вакуума молоко через входное отверстие патрубка 2 поступает в приемную камеру 1 и из нее по патрубку 9 сливается в мерную камеру 3, при этом поплавок 5 всплывает. При наполнении камеры 3 до определенного уровня поплавок 5 перекрывает отверстие патрубка 9, причем за счет сообщения камеры 3 с атмосферой посредством отверстия 4 давление в ней будет больше, чем в камере 1. Под действием перепада давлений в камерах 1 и 3 поплавок 5 прижимается к патрубку 9, а молоко поступает по трубке б и через ее суженный выходной конец 10 в виде струи, преодолевая зазор 11, попадает в отводной патрубок 8 и далее в молокопровод. При этом в трубке 6 за счет сужения ее выходного конца 10 создается повышенное давление на ее стенки, за счет чего пропорциональная часть проходящего по ней молока поступает в калиброванный канал 12. После удаления из камеры 3 всего молока из нее отсасывается воздух.Under the action of vacuum, milk through the inlet of the pipe 2 enters the receiving chamber 1 and from it through the pipe 9 merges into the measuring chamber 3, while the float 5 floats. When the chamber 3 is filled to a certain level, the float 5 closes the opening of the nozzle 9, and due to the communication of the chamber 3 with the atmosphere through the hole 4, the pressure in it will be greater than in the chamber 1. Under the action of the differential pressure in the chambers 1 and 3, the float 5 is pressed against the nozzle 9, and milk flows through tube b and through its narrowed outlet end 10 in the form of a jet, overcoming the gap 11, enters the outlet pipe 8 and then into the milk line. At the same time, in the tube 6, due to the narrowing of its outlet end 10, increased pressure is created on its walls, due to which a proportional part of the milk passing through it enters the calibrated channel 12. After removing all milk from the chamber 3, air is sucked out.

Когда давление в камерах 1 и 3 сравнивается, поплавок 5 под действием своего веса и напора молока падает вниз, и молоко снова начинает поступать из камеры 1 в мерную камеру 3.When the pressure in chambers 1 and 3 is compared, the float 5 under the influence of its weight and the pressure of milk falls down, and milk again begins to flow from chamber 1 into the measuring chamber 3.

В дальнейшем цикл повторяется.Subsequently, the cycle repeats.

Молоко поступает через патрубок 13 в мензуру, с помощью которой определяют количество прошедшего через устройство молока, для чего мензура имеет масштабную шкалу, проградуированную, например, в килограммах. Из мензуры берут также пробы молока.Milk enters through the nozzle 13 into the scale, with which the amount of milk passed through the device is determined, for which the scale is scaled, graduated, for example, in kilograms. Milk samples are also taken from the scale.

Предлагаемое устройство для дозирования жидкостей по сравнению с извест'ным просто по своей конструкции и удобно в обслуживании.The proposed device for dispensing liquids in comparison with the known one is simple in design and easy to maintain.

(54) DISPENSING DEVICE The invention relates to devices for dispensing hygiene contaminants passing through a pipeline system under vacuum, in particular, devices for measuring the quantity and sampling of milk from each korsuy when milking milking machines. The closest solution to the invention in terms of technical and attainable results is a device for the questioning of liquids, consisting of a chamber with an inlet branch pipe, a measuring cabinet mounted below it with a hole in the side wall and located in it with a float and a supply tube, the upper end of which is located in the receiving chamber, the drain tube communicated by the calibrated channel with the feed tube, and the branch pipe, the receiving chamber communicating with the metering chamber 1 The presence of a drain chamber in this device considerably complicates its intercept rukshpo makes it netohnologichnoy. In addition, in the case of the device there are LIQUIDS, accessible places for washing and routine inspection. The chain of the invention is to simplify the design of the device, improving the manufacturability of its manufacture and ease of maintenance. This is achieved by the fact that in the proposed device for dispensing liquids, preferably milk, the discharge pipe is mounted in the receiving chamber opposite the output end of the feeding tube. FIG. Figure 1 shows schematically a device for dispensing liquids, a profile section; in fig. 2 - the same, with a measuring chamber filled with liquid. The device contains a receiving chamber 1 with an inlet nozzle 2, a measuring chamber 3 with an opening 4 in the side wall for communication with the atmosphere and a float 5 located in it and a delivery tube 6, a drain pipe 7 and an outlet nozzle 8. Measuring chamber 3 is mounted under the receiving chamber 1 and communicated with it through the pipe 9, and the output end 10 of the feed tube 6 is located in the receiving chamber. . . -; -: A branch pipe 8 is mounted in the receiving chamber 1 above the outlet end 10 of the sub-tube 6 with a gap 11. K serves to connect the device with the milk line (not shown). The inlet 2 serves to connect the device with the milking machine (not shown). The drain tube 7 of the sorbpten by the calibrated channel 12 with the feeding tube 6 is natpy6KCM 13 and can be connected to the measuring bone by a men- cer (not akaaana in the drawing). The device works as follows. - - Under the action of vacuum Milk through the code-hole of the nozzle 2 enters the receiving chamber 1 and. from it through pipe 9 is discharged into the measuring chamber 3, while the float 5 emerges. When the chamber 3 is filled to a certain level, the float 5 closes the opening of the nozzle 9, G1ritch0 through the message of the chamber 3c with the atmosphere through the opening 4, the pressure in it will be greater than in the chamber 1. Under the action of pressure difference in the chambers 1 and 3, the float 5 is pressed to the nozzle 9 , and milk enters through the tube b and through its narrowed outlet end 10 in the form of a jet, overcoming the gap 11, enters the outlet nozzle 8 and further into the milk conduit. With emsm in the tube 6, due to the narrowing of its output end, U, an increased pressure is created on its walls, due to which the milk passing through it is proportional to the caliber: bath channel 12. After removing from 3 all the milk from it is exhausted. When the pressure in chambers 1 and 3 is compared, the float 5 under the action of its weight and the head of the mopoc drops down, and the milk again begins to flow from chamber 1 into the measuring chamber 3. The cycle then repeats. The milk enters through the nozzle 13 into the scale, with the help of which the quantity of milk passed through the device is determined, for which the scale has a scale, proped, for example, in kilograms. Milk samples are also taken from the scale. The proposed device for dispensing liquids is compared with that known only by its design and is convenient to maintain. The formula of the invention is a device for dispensing liquids, preferably a tank, consisting of a receiver with an inlet pipe, mounted under the measuring chamber with an opening in the side wall and a flashing chamber in it - -. the tube, the upper end of which is located in the receiving chamber, the drain tube communicated by the calibrated channel from the supply pipe and the branch pipe, the receiving chamber is in communication with the metering chamber, which, in order to simplify the device design, the branch pipe is mounted opposite the chamber output end of the delivery tube.
