The invention discloses a low-pressure vacuum tube and relates to the technical field of vacuum tubes. According to the technical scheme, the low-pressure vacuum tube is characterized by comprising avacuum tube body, and an end connecting joint and an end pressure releasing joint are connected to the two ends of the vacuum tube body respectively; sleeve ends are arranged at the two ends of the vacuum tube body, and inner concave rings are arranged at the sleeve ends; one end of the end connecting joint is plugged in the corresponding sleeve end and is provided with a connecting fixing annulargroove matched with the corresponding inner concave ring; and one end of the pressure releasing joint is plugged in the corresponding sleeve end and provided with a pressure releasing fixing annulargroove matched with the corresponding inner concave ring. According to the low-pressure vacuum tube, the vacuum tube body is adopted as a pipeline, the end connecting joint and the end pressure releasing joint are connected to the two ends of the vacuum tube body respectively, the corresponding inner concave ring is used for being connected and matched with the connecting fixing annular groove, the corresponding inner concave ring is used for being connected and matched with the pressure releasing fixing annular groove, and thus the purpose of reducing the weight and cost of the tube body of the low-pressure vacuum tube are achieved.

    本发明公开了一种低压真空管,涉及真空管技术领域,其技术方案要点包括真空管体,所述真空管体的两端分别转动连接有端部连接接头和端部泄压接头;所述真空管体的两端均设置有套管端,所述套管端设置有内凹环;所述端部连接接头的一端插接在所述套管端内,并设置有与相应的所述内凹环匹配的连接固定环槽;所述端部泄压接头的一端插接在所述套管端内,并设置有与相应的所述内凹环匹配的泄压固定环槽。本发明通过采用真空管体作为管路,在真空管体的两端分别转动连接端部连接接头和端部泄压接头,且分别采用内凹环与连接固定环槽连接匹配和内凹环与泄压固定环槽连接匹配,进而达到减轻该低压真空管管体重量以及成本的目的。
