Description

(54) ПРОМЫВОЧНЫЙ УЗЕЛ ГИДРОМОНИТОРНОГО(54) WASHING KNOT HYDROMONITOR

ДОЛОТАBITS

1one

Изобретение относитс ,к области буровой техники, а именно к промывоным уэл м гидромониторных буровых долот.The invention relates to the field of drilling equipment, namely to wash wells of jetting drill bits.

Известен промывочный узел гидромониторного долота, содержащий корпус с каналом, насадку и крепежный элемент, выполненный в виде забивного стержн , который установлен в совмещенных кольцевых проточках корпуса и насадки 1 .Known flushing unit jetting bit, comprising a housing with a channel, a nozzle and a fastening element, made in the form of a drive rod, which is installed in the combined annular grooves of the housing and the nozzle 1.

Недостатком этого пролывочного узла  вл етс  больша  трудоемкость монтажа и демонтажа, св занна  со сложностью установки и извлечени  забивного стержн .The disadvantage of this pouring unit is the large laboriousness of installation and disassembly, which is associated with the complexity of installation and removal of the drive rod.

Наиболее близким к описываемому изобретению по технической сущности и достигаемому результату  вл етс  промывочный узел гидромониторного долота, содержащий корпус с каналом на боковой поверхности которого выполнена кольцева  проточка, конусную насадку и крепежную втулку с уплотнительным кольцом 2.The closest to the described invention to the technical essence and the achieved result is a flush unit of a jetting bit, comprising a housing with a channel on the side surface of which a ring groove, a tapered nozzle and a mounting sleeve with a sealing ring 2 are made.

Использование конусной насадки и уплотнительного кольца с внутренним конусным гнездом повИшает долговечность работы данного промывоч (Ного узла.The use of a cone nozzle and a sealing ring with an internal cone socket increases the durability of this flushing operation (Node assembly.

Однако при высоких скорост х истечени  промывочной жидкости, что характерно дл  гидромониторных долот , надежность данного П13омывочн6го узла недостаточна. Св зано это с быстрым размьшом крепежного элемента .However, at high rates of outflow of the washing liquid, which is typical of jetting bits, the reliability of this washing unit is insufficient. This is due to the fast mounting of the fastener.

Цель- изобретени   вл етс  повышение надежности работы промывоч0 ного узла.The purpose of the invention is to improve the reliability of the washing unit.

Указанна  цель достигаетс  тем, что крепежна  втулка выполнена в виде цанги с кольцевым буртом на наружной цилиндрической поверхнос5 ти, размешенным в. кольцевой проточке канала корпуса, и с внутренней конусной поверхностью, соответствующей наружной поверхности насадки.This goal is achieved by the fact that the fastening sleeve is made in the form of a collet with an annular collar on the outer cylindrical surface, which is placed in. annular groove of the channel housing, and with an inner conical surface corresponding to the outer surface of the nozzle.

На чертеже представлен общий вид промывочного узла в разрезе.The drawing shows a General view of the wash unit in the section.

Промывочный узел включает корпус 1 с каналом 2, конусную насадку 3 и крепежную втулку 4, котора  выпол5 нена в виде цанги с кольцевым буртом 5 на наружной цилиндрической поверхности. Этот бурт размещен в кольцевой проточке б, выполненной на боковой поверхности канала кор0 пуса.The flushing assembly includes a housing 1 with a channel 2, a tapered nozzle 3, and a mounting sleeve 4, which is made in the form of a collet with an annular collar 5 on the outer cylindrical surface. This collar is placed in the annular groove b, made on the lateral surface of the channel of the corpus.
