Изобретение относитс  к химической промышленности и машиностроению   может быть использовано дл  определени  количества свободного газа в жидкости нри ее производстве, а также при эксплуатации гидравлических систем агрегатов и машин.The invention relates to the chemical industry and mechanical engineering can be used to determine the amount of free gas in a liquid during its production, as well as during the operation of hydraulic systems of units and machines.

Известно устройство дл  определени  количества свободного газа в жидкости, содержаш,ее вертикальный герметичный корпус, запорные вентили, эластичн ю мембрану , закрепленную в отверстии, выполненном в стенке корпуса, и приспособление дл  перемещени  мембраны, нредставл юш ,ее цилиндр, установленный снаружи корпуса вдоль мембраны, в который помещен поршень 1.A device is known for determining the amount of free gas in a liquid, containing its vertical sealed enclosure, shut-off valves, an elastic membrane fixed in a hole made in the wall of the housing, and a device for moving the membrane, represented by a cylinder, mounted outside the housing along the membrane In which the piston 1 is placed.

Недостатком устройства  вл етс  возможность ошибки в определении количества газа из-за наличи  газовых включений, газовых подушек в цилиндре.The disadvantage of the device is the possibility of errors in determining the amount of gas due to the presence of gas inclusions, gas cushions in the cylinder.

Известно также устройство дл  определени  количества свободного газа в жидкости , содержащее герметичный корнус, запорные вентили, маиометр, эластичную мембрану, закрепленную в отверстии, выполненном в корпусе, и приспособление дл  перемещени  мембраны .It is also known a device for determining the amount of free gas in a liquid, comprising a pressurized cornus, shut-off valves, a pressure gauge, an elastic membrane fixed in a hole made in the housing, and a device for moving the membrane.

Недостатком такого устройства  вл етс  невысока  точность, потому что изменени  объема герметичного корпуса определ ютThe disadvantage of such a device is low accuracy, because changes in the volume of the sealed enclosure determine

по величине прогиба мембраны. Абсолютна  величина прогиба мала, поэтому дл  уменьшени  относительной погрешности необходимы точные приборы, а также тщательна  установка измерител  перемещени  в точке наибольшего прогиба. Кроме того, система вакуумировани  делает устройство довольно громоздким и сложным в эксплуатации .largest deflection of the membrane. The absolute value of the deflection is small; therefore, precision instruments are needed to reduce the relative error, as well as careful installation of a displacement meter at the point of greatest deflection. In addition, the evacuation system makes the device quite cumbersome and difficult to operate.

С целью повышени  точности измерений и упрощени  конструкции предлагаемое устройство снабжено емкостью дл  контрольной жидкости, установленной снаружи корпуса вдоль мембраны и пьезометрической трубкой.In order to improve the measurement accuracy and simplify the design, the proposed device is equipped with a container for a control fluid installed outside the housing along the membrane and a piezometric tube.

Кроме того, приспособление дл  перемещени  мембраны выполнено в виде винтового механизма со штоком, соединенным с ме мбраной.In addition, the device for moving the membrane is made in the form of a screw mechanism with a rod connected to the membrane.

На чертеже показано описываемое устройство , продольный разрез.The drawing shows the described device, a longitudinal section.

Устройство дл  определени  количества свободного газа в жидкости состоит из вертикального герметичного корпуса 1, запорных вентилей 2, манометра 3, эластичной мембраны 4, винтового механизма 5, св занного носредством штока 6 с мембраной , емкости 7 дл  контрольной жидкости с размещенной в верхней части пьезометрической трубкой 8.The device for determining the amount of free gas in a liquid consists of a vertical sealed enclosure 1, shut-off valves 2, a pressure gauge 3, an elastic membrane 4, a screw mechanism 5 connected by means of a rod 6 with a membrane, a container 7 for a control liquid with a piezometric tube placed in the upper part eight.
