Description

一种可三自由度调节的管道连接器 技术领域：
本发明涉及一种可三自由度调节的管道连接器。
背景技术：
风机在装配过程中，蜗壳出口管道与风机出口管件之间往往会出现装配误差。由于机柜钣金加工的误差、以及柜体受力变形的问题，管道装配误差有时可以达到厘米级。这种情况下普通的管道连接器已经无法满足需要。
发明内容：
本发明是为了解决上述现有技术存在的问题而提供一种可三自由度调节的管道连接器。
本发明所采用的技术方案有：一种可三自由度调节的管道连接器，包括内偏心管、外偏心管、压紧法兰和密封填料，所述内偏心管插入外偏心管内，压紧法兰和密封填料均套设于内偏心管上，且压紧法兰通过螺栓与外偏心管固定连接，压紧法兰将密封填料压触于内偏心管上，密封填料对内偏心管进行轴向限位；
所述内偏心管包括第一活套法兰、第一S形管和内套管，所述第一S形管的上、下端口均为平面状，内套管插接于第一S形管的下端口，且两者之间相互焊接，第一活套法兰套设于第一S形管的上端口壁上；
所述外偏心管包括连接法兰、外套管和第二活套法兰，所述连接法兰焊接于外套管上，第二活套法兰套设于外套管上，连接法兰通过螺栓与压紧法兰固定连接。
进一步地，所述压紧法兰中法兰孔的底部设有锥形状的第一填料压紧面，在连接法兰中法兰孔的顶部设有锥形状的第二填料压紧面。
进一步地，所述密封填料采用橡胶材料制成，密封填料的内径与内套管外径相同。
进一步地，所述外套管包括焊接成型的圆柱管部和S形管部，所述S形管部的上、下端口均为平面状，圆柱管部与S形管部的上端口一体成型。
本发明具有如下有益效果：
1)本发明可以同时在径向、周向、轴向三个自由度上进行调节，保证管道的自由对接。
2)在三个自由度上都有比普通管道补偿方式更大的调节范围。
径向调节范围为0～2×E1(E1为S形管的偏心距，选择不同角度和曲率的弯管就可以改变偏心距。所以E1并不是一个定值)，周向为0～360°，轴向范围仅受限于内套筒长度。
以某型风机的管道连接为例：
市场上能够采购到的普通管道连接器——拷贝林卡箍的调节范围为偏心1～2mm、轴向0～3mm；不锈钢管道连接/修补器的调节范围为偏心3～5mm，轴向0～10mm。
若选择S形管的偏心距为40mm，则本发明的调节范围为偏心80mm；若选择内套管长度200mm，则轴向0～150mm。比其他连接器的调节范围都大了一个数量级还多，而且可以还根据需要设计成不同调节范围的规格型号(轴向调节距离取决于内外套管长度。也是可以根据需要改变规格的。并不是只能做这么大)。
3)本发明的连接器全部采用标准零件制造或改造，原料获取方便，制造方便。
本连接器的制造零部件全部可以从标准件市场上直接采购。包括活套法兰、两种规格的直管、45°弯管、普通法兰、橡胶密封环等。
其中只有普通法兰需要在车床上车制锥面，改造为套管压紧法兰。其他零件都可以直接使用。
4)本发明可以作为通用管道连接器使用。
和根据管道位置临时焊接的固定弯管连接相比，本发明的连接器尺寸可以自由调节。因此允许事先制备，并在需要使用时直接安装使用，无需临时改制。
即可以作为通用管道部件制造、使用。
5)本发明的管道连接器全部使用标准法兰连接，因此现场安装方便、连接安全可靠。
附图说明：
图1为本发明爆炸图。
图2为本发明结构图。
图3为本发明中内偏心管的结构图。
图4为本发明中外偏心管的结构图。
图5为本发明中压紧法兰的结构图。
具体实施方式：
下面结合附图对本发明作进一步的说明。
如图1至图5所示，本发明公开一种可三自由度调节的管道连接器，包括内偏心管1、外偏心管2、压紧法兰3和密封填料4，内偏心管1插入外偏心管2内，压紧法兰3和密封填料4均套设于内偏心管1上，且压紧法兰3通过螺栓与外偏心管2固定连接，压紧法兰3将密封填料4压触于内偏心管1上，密封填料4对内偏心管1进行轴向限位。
压紧法兰3拧紧后，密封填料4被两个填料压紧锥面向内挤压、内孔缩小，从而压紧内偏心管1并保证密封，同时通过密封填料4与内偏心管1的摩擦力保证管道不会继续轴向移动。
内偏心管1包括第一活套法兰11、第一S形管12和内套管13，第一S形管12的上、下端口均为平面状，内套管13插接于第一S形管12的下端口，且两者之间相互焊接，第一活套法兰11套设于第一S形管12的上端口壁上。
第一活套法兰11是标准件，可以沿着管道轴线自由旋转。第一S形管12两端平行，偏心距记为E1。内套管13的外径略小于第一S形管12的内径。
外偏心管2包括连接法兰21、外套管22和第二活套法兰23，连接法兰21焊接于外套管22上，第二活套法兰23套设于外套管22上，连接法兰21通过螺栓与压紧法兰3固定连接。
外套管22包括焊接成型的圆柱管部221和S形管部222，S形管部222的上、下端口均为平面状，圆柱管部221与S形管部222的上端口一体成型。
第二活套法兰23是标准件，可以沿着管道轴线自由旋转。S形管部222两端平行，偏心距记为E2。外套管22的内外径与S形管部222的尺寸相同。
内偏心管1的偏心距E1与外偏心管2的偏心距E2相同。
压紧法兰3中法兰孔的底部设有锥形状的第一填料压紧面31，在连接法兰21中法 兰孔的顶部设有锥形状的第二填料压紧面212。
压紧法兰3的法兰孔内的第一填料压紧面31用以将填料压紧在内套管上。
本发明利用双偏心管+活套法兰，形成一个同偏心度的双偏心环机构，达成在0～2倍偏心距范围的径向、360°周向任意可调。内、外套筒可以允许连接器沿着管道轴线方向有很大的伸缩范围。
密封填料4采用橡胶材料制成，密封填料4的内径与内套管13外径相同。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下还可以作出若干改进，这些改进也应视为本发明的保护范围。
