Abstract
Изобретение позвол ет повысить надежность штуцерного соединени трубопроводов при циклических изгибных нагрузках. Ниппель 2 с хвостовиком, штуцер 1 и уплотнительный элемент 3 между ними ст нуты накидной гайкой 4. Хвостовик выполнен длиной, равной 1,5-4 диаметра проходного сечени штуцера 1, и размещен в нем с зазором. 2 ил.The invention makes it possible to increase the reliability of the nipple joint of pipelines under cyclic bending loads. A nipple 2 with a shank, a fitting 1 and a sealing element 3 between them are fastened with a cap nut 4. The shank is made 1.5-4 times the diameter of the flow area of fitting 1 and is placed in it with a gap. 2 Il.
Description
Изобретение относитс к области судовых энергетических установок и предназначаетс дл применени на паропроводах и других трубных систем.The invention relates to the field of ship power plants and is intended for use on steam lines and other pipe systems.
Целью изобретени вл етс повышение надежности соединени при циклических изгибных нагрузках.The aim of the invention is to increase the reliability of the connection under cyclic bending loads.
На фиг. 1 изображено штуцерное соединение трубопроводов; на фиг. 2 работа (схе- матично) соединени в услови х циклических нагрузок.FIG. 1 depicts a choke connection of pipelines; in fig. 2 operation (schematically) of the connection under the conditions of cyclic loads.
Соединение состоит из штуцера 1, вставленного в него с зазором по скольз щей посадке ниппел 2 с удлиненным хвостовиком на длину 1.5-4 диаметра проходного сечени штуцера, уплотн ющего элемента 3, накидной гайки 4, кольца 5. The connection consists of a fitting 1 inserted into it with a gap on a sliding fit nipple 2 with an elongated shank for a length of 1.5-4 diameters of the flow area of the fitting, sealing element 3, cap nut 4, ring 5.
Соединение работает следующим образом .The connection works as follows.
При возникновении изгибных нагрузок на ниппеле 2 хвостовик ниппел передает нагрузки непосредственно на штуцер, т.е. хвостовик не допускает перемещение ниппел относительно штуцера 1. Этому способствует также наличие скольз щей посадки между хвостовиком ниппел и штуцером .When bending loads occur on the nipple 2, the nipple shank transfers the loads directly to the nozzle, i.e. the shank prevents the nipple from moving relative to the nipple 1. This is also facilitated by the presence of a sliding fit between the nipple shank and the nipple.
При работе штуцерного соединени в услови х циклических изгибных нагрузок смещение ниппел относительно штуцераWhen the choke is operating under cyclic bending loads, the nipple is offset from the choke

где А - величина зазора;where a is the size of the gap;
L - длина хвостовика ниппел ;L is the length of the shank nipple;
а-угол смещени ниппел относительно штуцера.a is the angle of displacement of the nipple relative to the choke.
Чем больше величина (длина хвостовика ниппел ) и чем меньше зазор между ниппелем и штуцером, тем меньше угол смешени ниппел относительно штуцера.The larger the value (the length of the nipple shank) and the smaller the gap between the nipple and the nipple, the smaller the mixing angle of the nipple relative to the nipple.
