Description

Изобретение относитс  к области маши строени , в частности к резьбовым соедин ни м труб, и может быть использовано в различных машинах и аппаратах, а также дл  соединени  газо- и нефтепроводов. Известны резьбовые соединени  труб с помощью муфты. Цель изобретени  - повышение гермети ности резьбового соединени  труб. Это достигаетс  благодар  увеличению длины резьбовой части соедин емьк труб путем выполнени  соединительной муфты с резьбовыми кольцевыми проточками на тор цах, в которых размещены уплотнительные кольца, Соедин емые трубы выполнены с соответствующими резьбовыми выступами, вход щими в кольцевые проточки. , На фиг. 1 изображено резьбовое соединение , разрез; на фиг. 2 - сопр гаемые элементы четьфехрезьбового соединени . Муфта 1 выполнена с кольцевыми проточками , на пов хност х которых нарезаны резьбы Md,,Nd2,Mds,Md4 с одинаковьп t шагом. Трубы 2 и 3 вьшолнены с соответствующими выступами, на поверхност х которых нарезаны резьбы Md,, И42, Mdj и чала захода резьб, обозначенные буквами . 4 i одной плоскости . В проточках муфты 1 и на торцах труб 2 и 3 размешены уплотнительные кольца 4 и 5. Сборка соединени  осуществл етс  следующим образом. В проточках муфты 1 и на выступах труб 2 и 3 помещаютс  уплотнительные кольца 4 и 5, затем муфту вначале навинчивают на трубу 2, а трубу 3 ввинчивают в муфту. Дл  повышени  производительности монтажа трубопроводов операции сборки можно совместить, дл  этого в муфте с одного торца в проточках нарезаетс  права  резьба , ас другого - лева . Соответствующие резьбы нарезаютс  на выступах соедин емых труб.The invention relates to the field of machine construction, in particular to threaded pipe joints, and can be used in various machines and apparatus, as well as for connecting gas and oil pipelines. Threaded pipe joints are known with a sleeve. The purpose of the invention is to increase the tightness of a threaded pipe joint. This is achieved by increasing the length of the threaded part of the pipe joining by making a coupling with threaded annular grooves on the ends in which the sealing rings are placed. The connected pipes are made with corresponding threaded protrusions that enter the annular grooves. , FIG. 1 shows a threaded connection, a cut; in fig. 2 - matching elements of a chafet threaded connection. Clutch 1 is made with annular grooves, on the surfaces of which thread Md ,, Nd2, Mds, Md4 are cut with the same t step. The pipes 2 and 3 are made with the corresponding protrusions, on the surfaces of which the threads Md, I42, Mdj and the beginning of the approach of the threads, marked with letters, are cut. 4 i one plane. O-rings 4 and 5 are placed in the grooves of the coupling 1 and at the ends of the pipes 2 and 3. The assembly of the joint is carried out as follows. In the grooves of the coupling 1 and on the projections of the pipes 2 and 3, sealing rings 4 and 5 are placed, then the coupling is first screwed onto the pipe 2, and the pipe 3 is screwed into the coupling. To increase the productivity of pipeline installation, assembly operations can be combined; for this, the right thread is cut in the groove in one socket and the other in the grooves on the left. The corresponding threads are cut at the protrusions of the pipes to be joined.
