; Изобретение относитс к гидротранспорт ным системам и может найти применение в системах дл транспортировки воды, пульпы, нефти т. п.; The invention relates to hydrotransport systems and can be used in systems for transporting water, pulp, oil, etc.

По сновному авт, св. № 2264О6 известек пневмокомленсатор, выполненный в виде корпуса, заполненного капсулами со сжатым газом.According to the main author, St. No. 2264О6 lime pneumocompensator, made in the form of a housing filled with compressed gas capsules.

Известный пневмокомпенсатор не позвол ет полностью заполнить корпус капсулами со сжатым газом при работе системы, иногда капсулы сжимаютс при увеличении давлени .The known pneumocompensator does not allow the body to be completely filled with compressed gas capsules during operation of the system, sometimes the capsules are compressed with increasing pressure.

Цель изобретени - полное использование объема корпуса.The purpose of the invention is to fully utilize the volume of the body.

Это достигаетс тем, что нижн часть корпуса предлагаемого пневмокомпенсатора перед местом подключени к нагнетательному трубопроводу соединена с бункером, заполненным капсулами со сжатым газом, через перекрываемую в местах соединени промежуточную трубу, св занную задвижкой с :нагнетательным трубопроводом и имеющую вентиль, соедин ющий ее полость с атмосфе рой . На чертеже изображен предлагаемый пневThis is achieved by the fact that the lower part of the body of the proposed pneumatic compensator is connected to a hopper filled with capsules with compressed gas, through a connecting pipe connected to the connecting pipe with: a pressure pipe and having a valve connecting its cavity atmosphere. The drawing shows the proposed pne

|Мокомпенсатор. Он состоит из корпуса 1, нижн часть которого перед местом подключени к нагнетательному трубопроводу 2 со;единена с бункером 3, заполненным капсула|ми 4 со с-катыи газом, через промежуточ|ную трубу 5, имеющую на хонйах задвижки 6 и 7, а также задвижку 8, установленную в месте подсоединени промежуточной трубы к нагнетательному трубопроводу, на котором {установлен обратный клапан Р.| Mokompensator. It consists of a housing 1, the lower part of which, in front of the connection to the injection pipeline 2, is united with the hopper 3 filled with capsules 4 with gas and gas, through an intermediate pipe 5 having valves 6 and 7 on the honyah, and also a valve 8 installed at the point of connecting the intermediate pipe to the discharge pipeline, on which {the check valve P. is installed.

Рабоча жидкость подаетс в нагнетательный трубопровод насосом 10.The working fluid is supplied to the discharge line by the pump 10.

Дл сообщени полости промежуточной трубы с атмосферой служит вентиль 11. j Компенсатор работает следующим обрагЗОМ .A valve 11 serves to communicate the cavity of the intermediate pipe with the atmosphere. J The compensator operates as follows.

Claims

Prior to launching the system and filling the injection pipe with working fluid under pressure, elastic capsules 4 pre-filled with air are placed through the hatch in housing 1. After launching At {coca 10, the working fluid will begin to flow into housing 1, the static pressure at the point of attachment of the pneumatic compensator to the pipes, wire 2 will compress the capsules 4 and part of the volume of the iKopnyca 3 will be filled with liquid. At this moment, the valves 6, 7 and I and the valve 11 are closed. The valve 11 and the valve 6 are opened, the intermediate pipe 5 is filled with capsules 4 from the hopper 3. The valve 1 1 is closed and the valve 6 U opens the valve 7 and I, with a pressure gap in the connection section of the intermediate pipe 5 to the practical pipeline 2 and section attaching the housing 1 to it, the capsules are mixed into the housing 1. The valves 7 and I are closed, and the cycle is repeated again until the volume of the housing 1 is completely filled with capsules 4. The invention The pneumo-compensator for extinguishing lp. pressure c hydraulic lines x aut. St. 226406, characterized in that, for the purpose of full utilization (of the Case Volume, its lower part, in front of the connection point to the discharge pipeline, is connected to a bunker filled with compressed gas capsules through an intercepting pipe connected to the discharge pipe connected valve connecting its cavity with the atmosphere.
