Abstract
Сущность изобретени : корпус с разреженным пространством установлен коакси- ально трубопроводу и уплотнен относительно него. Корпус выполнен из изол ционного материала, уплотнени .- в виде закрепленных на трубопроводе стальных колец омегообразного сечени , выполненных из упругого материала и обжимающих торцовые стенки корпуса. Средства поддерживани вакуума состо т из расположенного на корпусе патрубка с обратным клапаном и заглушкой. 2 ил.SUMMARY OF THE INVENTION: A housing with a rarefied space is mounted coaxially with the pipeline and sealed relative to it. The casing is made of insulating material, gaskets. - in the form of steel rings of omega-shaped section fixed on the pipeline, made of elastic material and compressing the end walls of the casing. The vacuum support means consists of a nozzle located on the body with a check valve and a plug. 2 ill.
Description
Изобретение относитс к машиностроению , в частности к изол ции трубопроводов.The invention relates to mechanical engineering, in particular to pipe insulation.
Целью изобретени вл етс улучшение условий эксплуатации.An object of the invention is to improve operating conditions.
На фиг. 1 представлен трубопровод с вакуумной изол цией в разрезе; на фиг, 2 - ,узел I на фиг. 1.In FIG. 1 is a sectional view of a pipeline with vacuum insulation; in fig. 2 -, node I in fig. 1.
Трубопровод 1 с вакуумной изол цией содержит установленный коаксиально ему и уплотнительный относительно него корпус 2 с разреженным пространством между ним и трубопроводом 1 и средства 3 поддержани вакуума, состо щие из расположенного на корпусе патрубка с обратным клапаном и заглушки при этом корпус 2 выполнен из изол ционного материала, а уплотнени - в виде закрепленных на трубопроводе 1 стальных колец 4 омегообразного сечени , выполненных из упругого материала и обнимающих торцовые стенки корпуса 2.Pipeline 1 with vacuum insulation contains a housing 2 mounted coaxially to it and a sealing relative to it 2 with a rarefied space between it and the pipe 1 and means 3 for maintaining vacuum, consisting of a nozzle with a check valve located on the housing and plugs while the housing 2 is made of insulating material, and seals - in the form of steel rings 4 of an omega-shaped section fixed on the pipeline 1, made of elastic material and hugging the end walls of the housing 2.
Конструкци вакуумной изол ции исключает необходимость расположени внутри изол ционного сло средств поддержани вакуума, которые расположены на патрубке корпуса 2. Кроме того, конструкци позвол ет унифицировать узел изол ции уплотнени ми концов секций, которые выполнены плотно посаженными за счет упругой деформации колец 4 и ими же уплотненнымнторцами корпуса 2 изол ции. Вакуум в пространстве между трубопроводом 1 и корпусом 2 создаетс через патрубок 3 вакуумным насосом. Изол ционным материалом может быть термоустойчива пластмасса.The design of the vacuum insulation eliminates the need to place inside the insulating layer means of maintaining vacuum, which are located on the nozzle of the housing 2. In addition, the design allows to unify the isolation unit with seals of the ends of the sections, which are tightly seated due to the elastic deformation of the rings 4 and them sealed with the ends of the isolation casing 2. Vacuum in the space between the pipe 1 and the housing 2 is created through the pipe 3 by a vacuum pump. The insulating material may be heat-resistant plastic.
