(54) ПОДЪЕМНИК ЖИДКОСТИ(54) LIFT LIFT

1one

Изобретение относитс к насосостроению , в частности к устройствам дл повышени напора одной жидкости за счет перепада давлений второй жидкости, и может быть использовано дл подачи различных жидкостей на более высокие отметки по сравнению с используемым перепадом давлени второй жидкости, например, сбросных , дренажных, коммунальных и других видов вод и жидкостей.The invention relates to pump engineering, in particular, to devices for increasing the pressure of one liquid due to the differential pressure of the second liquid, and can be used to supply various liquids to higher elevations compared to the used differential pressure of the second liquid, such as waste, drainage, utility and other types of water and liquids.

Известен подъемник жидкости, содер- жащий ступенчатой поршень, трубопроводы подвода и отвода активной жидкости с расположенными в них поворотными заслонками , снабженными блокирующими секторами , нагнетательный трубопровод с об .ратным клапаном, размещенный со стороны ступени порщн меньшего диаметра, и резервуар с перекачиваемой жидкостью, подсоединенный к нагнетательной камере при помощи подающего трубопровода 1.A fluid lift is known, which contains a stepped piston, pipelines for supplying and discharging active liquid with rotary valves located in them, equipped with blocking sectors, a discharge pipe with an external valve, located on the side of the piston stage of a smaller diameter, and a reservoir with pumped liquid connected to the injection chamber using the feed pipe 1.

Недостатком такого подъемника вл етс возможность контакта между активной и перекачиваемой жидкост ми, что приводит к невозможности перекачивани , например , масла или молока с помощью воды и т. д.The disadvantage of such an elevator is the possibility of contact between the active and pumped liquids, which makes it impossible to pump, for example, butter or milk using water, etc.

Цель изобретени - предотвращение KOKtaKTa между активной и перекачиваемой жидкост ми.The purpose of the invention is to prevent KOKtaKTa between active and pumped fluids.

Поставленна цель достигаетс тем, что в устройстве ступени порщн выполнены в виде сильфонов и между ними расположена перегородка.The goal is achieved by the fact that in the device the steps of the shell are made in the form of bellows and between them is a partition.

На чертеже схематически показан подъем ник, продольный разрез.The drawing schematically shows the rise of the nickname, a longitudinal section.

Claims

The fluid elevator contains a stepped piston, pipelines 1 and 2 for supplying and discharging the active liquid with rotary valves 3 and 4 located in them, equipped with blocking sectors 5 and 6, discharge pipe 7 15 with a check valve 8 located on the side of the stage of a smaller diameter, and a reservoir 9 with pumped liquid, connected to the discharge chamber 10 by means of a supply pipeline I, the steps of which are formed as bellows 12 and 13, and a partition 14 is located between them. The lift is soda INH limiter 15 also pivoting the flap 3 and the latter has a counterweight 16. The lift fluid operates as follows. The fluid coming from the supply pipe 1 enters the space under the partition 14. Under the action of hydrostatic and / or respectively formed high-speed water pressure, the butterfly valve 3 opens, since the moment of the water pressure force on the upper part of the valve 3 will be less than the moment of the water pressure force on the lower part valves 3. The water entering the space under the partition 14 creates pressure, which causes the partition 14 to move upwards, stretching the corrugated walls of the bellows 13, compressing the corrugated walls of the bellows and 12 and pushing the water out of the bellows 12 into the discharge pipe 7. When the bellows 12 is fully compressed and the bellows 13 is stretched, the pressure in the space under the partition 14 is equalized with the pressure behind the valve 3. After equalizing the pressure on the right and left of the valve 3, taking into account the presence of sector 5 and the counterweight 16, the flap 3 is closed. The valve 4, located on the side of the pipeline 2 of the outlet, opens only when the valve 2 is closed, as sector 5 blocks its opening. In flap 4, its part, located to the left of the axis of rotation, exceeds the right part, but the right part is made higher than the left part, taking into account the presence of a blocking sector 6. Water pressure on the left part of the flap 4 creates a torque of a little more than the right the flap 4 part together with the sector 6. As soon as the flap 3 closes, the flap 4 rotates around an axis counterclockwise, and a reduced pressure is created in the space under the partition 14. The corrugated walls of the bellows 12 expand, and the walls of the bellows 13 are compressed, the check valve 8 is closed, and the pumping fluid enters the space above the partition 14. After equalizing the pressure from the top and bottom, the valve 4 in the presence of sector 6 closes because the axis will be greater than the moment weight of its left side. After the shutter 4 is closed, the shutter 3 opens and the cycle repeats. The advantage of the proposed lift is the ability to lift various liquids, both incompressible and compressible, such as air, milk, oil, by using the energy of another liquid (for example, water of any quality). Claim of Invention A fluid elevator comprising a stepped piston, active fluid inlet and outlet pipelines with rotary valves located in them, provided with blocking sectors, discharge pipe with a check valve, located on the side of a piston stage of smaller diameter, and a reservoir with pumped liquid connected to the discharge chamber by means of a supply line, characterized in that, in order to prevent contact between the active and pumped liquids, The cable is made in the form of bellows and a partition is located between them.
