Description
Изобретение относитс к машиностроению , а именно к способам герметичных резьбовых соединений металлических деталей, и может быть использовано дл соединени трубопроводов высокого давлени .The invention relates to mechanical engineering, in particular to methods for hermetic threaded joints of metal parts, and can be used to connect high pressure pipelines.
Цель изобретени - повышение производительности способа путем создани в зоне резьбового соединени очагов повышенной температуры.The purpose of the invention is to increase the productivity of the method by creating in the zone of a threaded joint of high-temperature foci.
На фиг. 1 представлено соединение, разрез; на фиг. 2 - узел I на фиг. 1.FIG. 1 shows the connection section; in fig. 2 — node I in FIG. one.
На конусную резьбовую поверхность одной из соедин емых деталей, например муфты 1, нанос т слой отверждающейс в зкой массы 2 типа К-1. В канавку резьбы помешают гранулы 3 м гкого металла, например свинцовую дробь. Эти гранулы равномерно распредел ют по поверхности. Размер гранул должен быть соизмерим с параметрами резьбы. Дл конусной трубной резьбы.On the tapered threaded surface of one of the parts to be joined, for example, coupling 1, a layer of K-1 type curing viscous mass 2 is applied. In the groove of the thread will prevent granules of 3 soft metal, such as lead shot. These granules are evenly distributed over the surface. The size of the granules should be commensurate with the parameters of the thread. For tapered pipe thread.
имеюшей шаг 3,175 мм, используют гранулы диаметром 1,0-1,2 мм. Муфту 1 навинчивают на трубу 4. После ручного навинчивани производ т доворот муфты усилием, достаточным дл раздавливани гранул (скорость навинчивани не менее 1 об.1с). По мере навинчивани муфты сокрашаетс величина межрезьбового радиального зазора, что приводит к деформации гранул, при этом механическа затраченна энерги переходит в тепловую, что приводит к нагреву поверхности муфты.having a pitch of 3.175 mm, granules with a diameter of 1.0-1.2 mm are used. The clutch 1 is screwed onto the pipe 4. After the manual screwing in, the clutch is forced to turn sufficiently to crush the pellets (the screwing speed is at least 1 vol. 1 s). As the coupling is screwed in, the size of the inter-threaded radial clearance is reduced, which leads to the deformation of the granules, while the mechanical energy expended becomes thermal, which leads to the heating of the coupling surface.
Таким образом, в зоне расположени гранул образуютс очаги повышенной температуры до 200С. При этих услови х полное отверждение состава в резьбе наступает после свинчивани деталей через 1-2 ч, что значительно быстрее по сравнению с другими известными способам соединени .Thus, in the location of the granules, hot spots of up to 200 ° C are formed. Under these conditions, complete curing of the composition in the thread occurs after screwing the parts in 1-2 hours, which is much faster than other known connection methods.
