Изобретение относитс к трубопроводному транспорту жидкостей и газов и предназначено дл присоединени ответвлени к действующему трубопро- воду без снижени в нем давлени .The invention relates to pipeline transport of liquids and gases, and is intended to connect a branch to an existing pipeline without reducing the pressure therein.
Цель изобретени - упрощение конструкции устройства.The purpose of the invention is to simplify the design of the device.
На фиг. 1 представлено устройство в рабочем положении, общий вид; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows the device in the working position, general view; in fig. 2 is a section A-A in FIG. one.
Устройство состоит из последовательно устанавливаемых на трубопроводе 1 переходнЪго патрубка 2, задвижки 3, приспособлени дл вырезки окна, выполненного в виде размещенного в герметичном корпусе 4 шпиндел 5, на котором закреплены снабжен-- ные шариковым захватом 6 центрирующее сверло 7, держатель 8 с подпру- жиненными резцами 9, контактирующими посредством шариковых п т 10 с поверхностью имеющего форму цилиндрического свода и закрепленного к наружной обойме 11 подшипника 12 каче- НИН копира 13,в теле которого выполнены диаметрально расположенные пазы 14 под закрепленные на переходном патрубке 2 планки 15.The device consists of a transitional pipe 2 in series 1 on the pipeline 1, a valve 3, a device for cutting a window, made in the form of a spindle 5 placed in an air-tight case 4, on which are mounted a centering drill 7 supplied with a ball grab 6, reed cutters 9, contacting by means of ball pt 10 with the surface of a cylindrical vault-shaped and fixed to the outer race 11 of the bearing 12 of the quality copier 13, in whose body they are diametrically arranged The grooves 14 under the straps 15 fixed on the transition nozzle 2.
Шпиндель 5 имеет привод 16 осево- го и углового перемещени .The spindle 5 has a drive 16 for axial and angular displacement.
Врезка отвода осуществл етс следующим образом.Inset tap is carried out as follows.
К действующему трубопроводу 1 привариваетс переходный патрубок 2 с направл ющими планками 15, после чего устанавливаютс задвижки 3 (с открытым шибером) и приспособление дл вырезки окна.A transition pipe 2 is welded to the existing pipeline 1 with guide bars 15, after which valves 3 (with an open gate) and a device for window cutting are installed.
Шпиндель 5 перемещают в сторону трубопровода 1 до соприкосновени центрирующего сверла 7 со стенкой трубы, что предопредел ет вход планок 15 в пазы 14 в копире 13.The spindle 5 is moved in the direction of the pipeline 1 until the centering drill 7 is in contact with the pipe wall, which determines the entry of the bars 15 into the slots 14 in the copier 13.
Затем включают привод 16 осевого и углового перемещени шпиндел 5 и производ т вырезку окна. При этомThen, the actuator 16 of the axial and angular movement of the spindle 5 is turned on and the window is cut. Wherein

режущие кромки резцов 9 за счет поверхности копира 13 движутс по пространственной кривой, соответствующе контуру вырезаемого окна. Неподвижность копира 13 в горизонтальной плоскости при вращении шпиндел обеспечиваетс за счет его закреплени к наружной обойме 11 подшипника 12 качени и размещени в пазах 14 планок 15.the cutting edges of the cutters 9 due to the surface of the copier 13 move along a spatial curve corresponding to the contour of the window being cut. The immovability of the copier 13 in the horizontal plane during the rotation of the spindle is ensured by fastening it to the outer race 11 of the rolling bearing 12 and placing slats 15 in the grooves 14.
После образовани в теле трубы сквозной кольцевой прорези шпиндель 5 перемещают вверх в полость г ерметич- ного корпуса 4 смеете с вырезанным п таком, который посредством шарикового захвата 6 удерживаетс от падени . Затем задвижку 3 закрывают, стравливают избыточное давление из полости корпуса 4 в атмосферу и демонтируют приспособление дл вырезки окна.After a through annular slot has been formed in the pipe body, the spindle 5 is moved upwards into the cavity and the hermetic case 4 is blended with a cut-out n such that it is kept from falling by means of a ball-shaped gripper 6. Then the valve 3 is closed, relieve excess pressure from the cavity of the housing 4 into the atmosphere and remove the device for cutting window.
Оставшийс на трубопроводе 1 переходной патрубок 2 с задвижкой 3 служит дл присоединени ответвлени к трубопроводу.The remainder of the pipe 1 of the transition pipe 2 with the valve 3 serves to connect the branch to the pipeline.
