The utility model relates to a by-pass straight pipe pressure balance compensator, which comprises an end pipe a with a medium through hole, an end pipe B with a medium through hole, a sealing packing box, an outer sleeve, an outer pipe component, a sealing plate and a corrugated pipe. Both ends of the corrugated pipe are sealed and connected with a sealing plate, and the sealing plates at both ends are respectively connected with an end pipe a and an end pipe B. the outer pipe component is sleeved on the outside of the corrugated pipe, and one end of the outer pipe component is welded on the end pipe On B, the other end of the outer tube assembly is welded with one end of the outer sleeve sleeved on the outside of the end tube a, and the other end of the outer sleeve is set on the end tube a through the sealing stuffing box, so that the end tube a, the outer sleeve, the outer tube assembly, the bellows and the end tube B are surrounded by an outer pressure passage with medium circulation. The compensator can be applied to the displacement compensation of long straight pipeline. The compensation element is the combination of sleeve and bellows, which expands the new idea of pipeline compensation design and reduces the application cost compared with the conventional bypass bellows compensator.
【技术实现步骤摘要】
一种旁通直管压力平衡型补偿器
本技术涉及补偿器,具体说的是一种旁通直管压力平衡型补偿器。
技术介绍
针对长直管线的位移补偿,通常采用波纹补偿器或套筒补偿器,旁通型波纹管补偿器在介质流速不高的场合有一定的应用,其特点为压力平衡结构,整个补偿器不对外输出盲板力。通常在热水和蒸汽系统管道中,波纹管的选材高于管道材质级别,波纹管通常采用奥氏体不锈钢,成本较高。
技术实现思路
为解决上述技术问题,本技术提供一种旁通直管压力平衡型补偿器,可应用于长直管线的位移补偿中,补偿元件为套筒和波纹管的组合,扩充了管路补偿设计的新思路,与常规采用的旁通波纹补偿器相比较,降低了应用成本。为实现上述技术目的,所采用的技术方案是:一种旁通直管压力平衡型补偿器,包括设有介质通孔的端管A、设有介质通孔的端管B、密封填料函、外套筒、外管组件、封板和波纹管,波纹管的两端密封连接有封板,两端的封板上分别连接有端管A和端管B,外管组件套设在波纹管外侧,外管组件的一端焊接在端管B上,外管组件的另一端与套设在端管A外侧的外套筒的一端焊接,外套筒的另一端通过密封填料函密封滑动设置在端管A上,使端管A、外套筒、外管组件、波纹管和端管B围成用介质流通的外压通道。本技术所述的密封填料函上连通有密封泥管咀。本技术有益效果是:该补偿器可以实现长直管线的位移补偿,位移补偿元件采用套筒和波纹管组合结构,降低了补偿器的整体应用成本,扩充了管路补偿设计的新思路。同时,波纹管作为外压结构,不存在柱失稳现象,补偿器的受力方面,封板结构受力与管道盲 ...
