Abstract

FIELD: valving. SUBSTANCE: sealing unit has a sealing ring set in the sealing housing of a valving member, e.g. in the gate housing or wedge. The sealing housing is provided with a ring conical truncated pin or groove. The sealing ring has two ring projections that form a cylindrical groove answered to the pin or groove. In addition, a drain- ventilation passageway is made in the sealing ring. After pressing the sealing ring in the seat place the passageway is plugged. The drain-ventilation passageway maybe made in the element of a valving member. EFFECT: enhanced reliability.

Изобретение относится к арматуростроению, в частности к конструкции узла уплотнения в запорном органе трубопроводной арматуры. Узел уплотнения обеспечивает полную герметичность соединения сопрягаемых поверхностей при снижении трудоемкости в ходе сборки узла. Узел уплотнения состоит из уплотнительного кольца, установленного в посадочном месте элемента запорного органа, например в корпусе задвижки или клине. В посадочном месте выполнен кольцевой конусный усеченный шип или паз, а уплотнительное кольцо имеет два кольцевых выступа, образующих ответный шипу или пазу цилиндрический паз. Кроме того, в уплотнительном кольце предусмотрен дренажно-вентиляционный канал, который после запрессовки уплотнительного кольца в посадочное место закрывается заглушкой. Дренажно-вентиляционный канал может быть выполнен в элементе запорного органа.The invention relates to valve engineering, in particular to the design of the seal assembly in the shut-off element of pipe fittings. The seal assembly provides complete tightness of the connection of the mating surfaces while reducing the complexity during assembly of the assembly. The sealing assembly consists of a sealing ring installed in the seat of the element of the locking element, for example, in the valve body or wedge. In the seat, an annular conical truncated spike or groove is made, and the sealing ring has two annular protrusions forming a cylindrical groove in response to the spike or groove. In addition, a drainage and ventilation channel is provided in the sealing ring, which, after pressing the sealing ring into the seat, is closed with a plug. The drainage and ventilation channel can be made in the element of the locking element.
