Предложено устройство для отбора изокинетических проб рабочей среды, протекающей под высоким давлением в резервуаре, сепараторе, теплообменнике, другом контейнере или трубе, имеющих по меньшей мере одну точку отбора проб. Чтобы несмотря на трудности, связанные с высоким давлением, производить рациональный отбор проб, изокинетический пробник содержит управляемый давлением рабочей среды поршневой цилиндр или другое подобное исполнительное устройство, соединенное или выполненное с возможностью соединения с запорным клапаном, выполненным с возможностью соединения с указанной точкой отбора. Запорный клапан, находясь в открытом положении, обеспечивает прохождение через него трубчатого штока поршня поршневого цилиндра. Шток поршня состоит из двух коаксиально установленных трубок. Свободный конец внутренней трубки выполнен с возможностью удобной установки и замены зонда, имеющего по меньшей мере одно приемное отверстие, причем ход поршня в предпочтительном варианте - переменный, позволяет выдвигать зонд со своим приемным отверстием в резервуар и т.п. поперек направления потока рабочей среды для отбора проб вдоль по меньшей мере большей части поперечного сечения потока.A device is proposed for taking isokinetic samples of a working medium flowing under high pressure in a tank, separator, heat exchanger, other container or tube having at least one sampling point. In order to make rational sampling despite the difficulties associated with high pressure, the isokinetic probe contains a piston-cylinder or other actuating device controlled by the pressure of the working medium, connected or configured to be connected to a shut-off valve configured to connect to the specified sampling point. The shut-off valve, being in the open position, ensures the passage through it of the tubular piston rod of the piston cylinder. The piston rod consists of two coaxially mounted tubes. The free end of the inner tube is made with the possibility of convenient installation and replacement of the probe having at least one receiving opening, and the piston stroke in the preferred embodiment is variable, allows you to extend the probe with its receiving opening to the tank, etc. transverse to the direction of flow of the sampling fluid along at least most of the flow cross section.
