Description
Известны приборы дл проверки внутреннего диаметра труб, наход п1 ,ихс под давлепием. В этих приборах примен ютс гидравлические передачи с указательными устройствами.Instruments are known for checking the internal diameter of pipes, which is found in P1, they are under pressure. These instruments use hydraulic gears with pointing devices.
Отличительна особенность описываемого прибора состоит в том, что он оборудован воспринимающей головкой, имеющей форму, обеспечивающую уравновещивание давлени в трубе. Головка прибора может быть выполнена в виде двух цилиндров, пропущенных через с- ответствующие уплотнени .A distinctive feature of the device described is that it is equipped with a sensing head having a shape that provides pressure balance in the pipe. The head of the device can be made in the form of two cylinders passed through the corresponding seals.
На чертеже схематически изображен описываемый лрибОр в общем виде.The drawing shows schematically the described mushroom in general.
Пробка 7 ввинчиваетс в стержень 2, устанавливаемый внутри провер емой трубы (на чертеже не показана). В пробке монтируетс воспринимающа головка 3, выполненна в виде щтока, на одном конце которого установлен порщень, а на другом-два разных диаметров цилиндра. По всей своей длине головка уплотнена сальниками 4. Конец цилиндрической части поршн закруглен по дуге, описанной внутренним радиусом измер емой трубы. Кра цилиндрического конца головки скощены под тупым углом.The plug 7 is screwed into the rod 2 installed inside the inspected pipe (not shown in the drawing). In the plug, a sensing head 3 is installed, made in the form of a slider, at one end of which a piston is mounted, and on the other, two different cylinder diameters. The head is sealed along its entire length by glands 4. The end of the cylindrical part of the piston is rounded in an arc described by the inner radius of the pipe being measured. The edges of the cylindrical end of the head are angled.
Головка такой формы соприкасаетс с внутренней поверхностью трубы по одной линии.A head of this shape is in contact with the inner surface of the pipe in a single line.
в .пробке просверлен канал 5 дл подвода жидкости под среднюю цилиндрическую часть порщн . В стержне 2 выполнен канал 6, соедин ющий подпоршневую полость головки с передаточной трубкой 7, в верхней части которой перемещаетс плунжер 8, сочлененный посредством зубчатой рейки 9 со стрелкой W. Нулевое положение стрелки по щкале // регулируетс гайкой 12.A channel 5 is drilled in the plug for supplying fluid under the middle cylindrical part of the core. The rod 2 has a channel 6 connecting the piston chamber of the head with the transfer tube 7, in the upper part of which the plunger 8 articulated by the gear rack 9 with arrow W moves.
Делени шкалы могут быть выполнены из электрических контактов, взаимодействующих с сигнализационной доской 13 (табло).Dividing the scale can be made of electrical contacts that interact with the alarm board 13 (scoreboard).
- Описываема воспринимаЮЩа головка при измерении внутренних диаметров труб, наход щихс под давлением, уравновешена от давлени внутри трубы.- The described sensing head, when measuring the internal diameters of pipes under pressure, is balanced by the pressure inside the pipe.
