Description

(54) САЛЬНИКОВОЕ УПЛОТНЕНИЕ С ПЛАСТИЧНОЙ НАБИВКОЙ(54) OIL SEALING WITH PLASTIC PACKING

Claims (2)

Изобретение относитс  к уплотнительной технике., Иэвестны сальниковые уплотнени , содержащие корпус и аксиально-подвиж ную крьмку, в которых в качестве уплотнени  испол$ эуетс  пластична  сал никова  набивка I. Эта конструкци  почти не использу ет возможностей пластичной набивки. Известна также конструкци  узла, в которой пластична  набивка Уплотн етс  в расточке сальниковой коробки с помоцью подающего устройства, вьшолненнрго в виде цилиндра и поршн , перемещашлого по резьбе 12}. Недостатком этрй конструкЦии  вл етс  неравномерность давлени  набивки по периметру вала иэ-эа потерь на трение по корпусу. Это вызывает чрезмерное давлением набивки на вал в районе подвода; дл  обеспечени  необходимого минимального давлени  набивки в диаметрально противоположной точке, что приводит к понижению надежности герметизации узла. Целью изобретени   вл етс  повышение надежности узла. Это достигаетс  тем, что в корпу:се выполнена дополнительна , изоли (рованна  от вала камера, соединен на  с нагнетающим устройством и отделенна  от рабочей камеры дросселирукнцим кольцевьв4 каналом. На чертеже изображено описываемое уплотнение, разрез. Корпус 1 уплотнени  с расточкой | соединен с устройством 3 дл  подачи пластичной набивки, Между расточкой 2 и устройством 3 дл  подачи пластичной набивки б асположена промежуточна  KeiMepa 4, соединенна  с расточкой 2 кольцевьм каналом 5. Уплотнение работает слёдуюцим образом . При попадании из устройства 3 дл  подачи пластичной набивки в прс ежуточиу камеру 4 пластична  набивка распредел етс  в последней, после чего через кольцевой канал 5 подаетс  в расточку 2. При давление набивКи по ;окрузКности выравниваетс , поскольку давление набивтси перераспредел етс  в промежуточной камере 4 и дополнительно выравниваетс  кольцевым каналс л 5. . Формула изобретени  Сальниковое уплотнение с пластичной набивкой, принудительно подава 690217The invention relates to a sealing technique. I-known stuffing seals, comprising a housing and an axially movable clamp, in which plastic seal I is used as a seal. This design almost does not use the possibilities of plastic packing. Also known is the design of the assembly in which the plastic packing is sealed in the bore of the stuffing box with the aid of a feeding device, which is in the form of a cylinder and a piston moved along the thread 12}. The disadvantage of this design is the unevenness of the packing pressure around the perimeter of the shaft, due to friction losses along the body. This causes excessive pressure of the packing on the shaft in the area of the supply; to provide the required minimum packing pressure at a diametrically opposite point, which leads to a decrease in the reliability of the sealing of the assembly. The aim of the invention is to improve the reliability of the site. This is achieved by the fact that the housing is complementary, insulated (the chamber is isolated from the shaft, connected to the pumping device, and separated from the working chamber by a throttled ring 4 channel. The drawing shows the seal described, the cut. The housing 1 with the boring | 3 for feeding plastic packing; Between the bore 2 and the device 3 for feeding the plastic packing, an intermediate KeiMepa 4 is placed, connected to the bore 2 by an annular channel 5. The sealing works in the following way. The device 3 for supplying plastic packing to the chamber 4 plastic packing is distributed in the latter, then through the annular channel 5 is fed into the bore 2. When the pressure of the packing is on, the loadings are equalized because the pressure is redistributed in the intermediate chamber 4 and is evenly aligned Channel 5. Formula of the invention. Omental seal with plastic gasket, forcibly submitted 690217 мой нагнетающим устройством в рабочую камеру, образованную расточкой корпуса и валом, отлич ающеес   тем, что, с целью повышени  Нсу1ежности узла, в корпусе выполнена дополнительна , изолированна  от вала, камера, соединенна  с нагнетающим устройством и отделенна  отMy pumping device into the working chamber formed by the bore of the body and the shaft is different in that, in order to increase the knotty of the assembly, the body is made additional, isolated from the shaft, the chamber connected to the pressure device and separated from рабочей камеры дросселирующим кольцевым каналом.the working chamber of the throttling annular channel.
