Изобретение относитс к испытательной технике, в частности к установкам дл испытани труб гидростатическим давлением.The invention relates to testing equipment, in particular to installations for testing pipes by hydrostatic pressure.
Известна установка дл испытани труб гидростатическим давлением, содержаща станину с подвижной и неподвижной заглушками , систему подачи рабочей среды через подвижную заглушку. и систему управлени 1.A known device for testing pipes with hydrostatic pressure, comprising a frame with movable and fixed plugs, and a system for feeding the working medium through a movable plug. and control system 1.
Указанна установка сложна по конструкции и имеет большой вес.This installation is complicated in construction and has a large weight.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс установка дл испытани труб гидростатическим давлением, содержаща размещаемый внутри испытуемой трубы цилиндрический корпус с установленными на обоих его концах уплотнительными , элементами в виде эластичных кольцевых камер и источник давлени , соединенный с полост ми кольцевых камер и с рабочей полостью, образованной внутренней поверхностью трубы, цилиндрическим корпусом и уплотнительными элементами 2.The closest to the invention in its technical essence and the achieved result is a hydrostatic pressure testing device for pipes, containing a cylindrical body placed inside the test pipe with sealing at its both ends, elements in the form of elastic annular chambers and a source of pressure connected to annular cavity cavities and with a working cavity formed by the inner surface of the pipe, a cylindrical body and sealing elements 2.
Недостатком данной установки вл етс низкое качество испытаний, вызванное тем, что необходимо перед началом создаватьThe disadvantage of this setup is the low quality of the tests, due to the fact that it is necessary to create
усилие между трубой и уплотнительными элементами больще испытательного давлени , а это создает перегрузку испытательной трубы.the force between the pipe and the sealing elements is greater than the test pressure, and this creates an overload of the test pipe.
Целью изобретени вл етс улучшение качества испытаний путем исключени перегрузки испытуемой трубы.The aim of the invention is to improve the quality of testing by eliminating the overload of the test pipe.
Поставленна цель достигаетс тем, что установка дл испытани труб гидростатическим давлением снабжена устройством дл создани противодавлени , выполненным в виде двух цилиндров - больщого и малого, жестко св занных между собой, подпорщнева полость большого цилиндра соединена с источником давлени , рабочей полостью и подпорщневой полостью малого цилиндра, а подпоршнева полость последнего соединена с полост ми кольцевых камер .The goal is achieved by installing a hydrostatic pressure test device equipped with a back pressure device made in the form of two cylinders, large and small, rigidly connected to each other, the podporshnevaya cavity of a large cylinder is connected to a pressure source, a working cavity and a podsteel cavity of a small cylinder , and the piston cavity of the latter is connected to the cavities of the annular chambers.
На чертеже показана установка дл испытани труб гидростатическим давлением.The drawing shows a device for testing pipes by hydrostatic pressure.
Установка содержит цилиндрический корпус 1, размещаемый внутри испытуемой трубы 2, уплотнительные элементы в виде эластичных кольцевых камер 3, установленные на обоих концах цилиндрического корпуса с помощью упорных колец 4, устройстThe installation contains a cylindrical body 1 placed inside the test pipe 2, sealing elements in the form of elastic annular chambers 3 mounted on both ends of the cylindrical body using stop rings 4, the device
