Description
установлен кожух 5, имеющий щелевые прорези 6, размещенные против скощенных вершин щестилранника. Кожух 5 жестко св зан с ниппелем и муфтой, например, сваркой. На торцах кожуха 5 жестко с помощью сварки установлены кольца 7, имеющие центральное отверстие дл размещени бурильных труб 8, св занных с ниппелем и муфтой замка, и отверсти дл воздухоподающих труб 9.a casing 5 is installed, having slotted slots 6, located against the shank-headed peaks of the genus. Case 5 is rigidly connected to the nipple and the coupling, for example, by welding. At the ends of the casing 5, rings 7 are rigidly fixed by welding, having a central opening for accommodating drill pipes 8 connected with a nipple and a lock coupling, and openings for air supply pipes 9.
Дл создани герметичности полости в кожухе 5 и в ниппеле 1 проточены канавки дл уплотнительных резиновых колец 10 и .//. To create an airtightness of the cavity in the casing 5 and in the nipple 1, grooves for sealing rubber rings 10 have been machined and .//.
Замок работает следующим образом.The lock works as follows.
Сжатый воздух при бурени но воздухоподающим трубам 9 поступает в гарметичнюе пространство между кожухом 5, ниппелем / с муфтой 2, а затем в еоздухопроводные трубы, и дальще процесс повтор етс .The compressed air during drilling but the air supply pipes 9 enters into the tight space between the casing 5, the nipple / with the coupling 2, and then into the air and air pipes, and further the process repeats.
Предлагаема конструкци замка позвол ет обеспечить раздельное прохождение пульпы и воздуха без увеличени гидравлических и аэродинамических сопротивлений с сохранением пр моточности прохождени воздуха в месте стыка муфты и ниппел независимо от того, совмещены контуры воздущных каналов или нет. Замок позвол ет замен ть детали, изнощенные вThe proposed lock design allows for separate passage of pulp and air without increasing hydraulic and aerodynamic resistance while maintaining the air flow through the joint between the coupling and the nipple, regardless of whether the contours of the air channels are aligned or not. The lock allows replacement of parts worn in
процессе эксплуатации, на новые, не затрагива бурильную щтангу.during the operation, on new, without affecting the drill shchtangu.
