设置调节杆和隔板的目的是可以手动或者自动的对隔板的位置进行调节，当调节杆转动时，由于螺纹部的存在使得调节杆可相对于第一盖轴向移动，进而带动隔板轴向移动，从而改变第一腔室和第二腔室的容积。调节杆可由手动驱动，也可设置驱动机构如电机等驱动。

通过设置第二盖，并将第二管设在第二盖上，可使得第一管、第二管相对于筒体的位置均可调整，当支架的安装位置相对于筒体是固定的情况下，也可很容易的调整两个管的位置，使储液器的接管操作更方便。
在一个实施例中，在前述的储液器中，所述第一盖和/或第二盖与所述筒体通过螺纹可转动的密封连接。
在使用状态下，将第一管与第二管位于所述第一腔室内的管口的高度基本相同，其目的是无需对第一管和第二管哪根作为进管、哪根作为出管进行区分，便于整机管路连接，进出管可以任意连接，大大提高生产效率。
在一个实施例中，在前述的储液器中，所述第一管和第二管的与外部连通的接口的相对位置可随所述第一盖和第二盖的相对转动而改变。

具体实施方式
以下基于实施例对本发明进行描述，但是本发明并不仅仅限于这些实施例。在下文对本发明的细节描述中，详尽描述了一些特定的细节部分。对本领域技术人员来说没有这些细节部分的描述也可以完全理解本发明。为了避免混淆本发明的实质，公知的方法并没有详细叙述。
图1、2所示是本发明的储液器结构。其包括第一盖1和罐体2，罐体和盖的内部形成腔室，罐体2一端开口，第一盖1的开口侧与罐体2的开口侧可转动的密封连接，还包括第一管7和第二管8用以连通所述腔室与外部，其中第一管7设于所述第一盖1上，所述第二管8设于所述罐体上。作为一种较优的实施方式，图1中第一盖1与罐体2之间采用的是螺纹 密封的方式连接，但不限于图1中的方式，还可采取如图4中所示的方式，在第一盖1和罐体2之间设置密封圈24，第一盖1的端部外侧设置螺纹部，在罐体2的外周设有限位凸台221，螺母23套设在限位凸台221的外周，限位凸台221对螺母轴向限位，螺母23与第一盖1的螺纹部之间通过螺纹连接，由密封圈24实现第一盖1和罐体2之间的密封连接，由螺母23将第一盖1可转动的固定在罐体2上，实现第一盖1与罐体2之间的可转动的密封连接。第一盖1用于密封罐体2上的开口，第一盖1与罐体2之间形成腔室。通过将第一盖1与罐体2之间可转动的密封连接，其中第一管7设于所述第一盖1上，所述第二管8设于所述罐体上的方式，第一管7与第二管8之间的相对位置可随着第一盖1的转动可调节，这样接管的位置可以根据现场的不同情况随时调整，并且调节非常方便，使管路的连接更简单，减少了管路的长度，并且减少了管道的弯折，有利于介质的顺畅流动。
作为一种实施方式，本发明的储液器还包括容积调节部，如图3所示，由隔板6和调节杆5组成，隔板6和调节杆5可一体制成，也可分体连接而成。隔板6将所述腔室分为第一腔室9和第二腔室10，第一腔室9与第二腔室10之间互相独立且不连通，其中将第一腔室9作为储液室，第二腔室10作为调节室。第一盖1呈杯状，包括底壁和侧壁。隔板6设置在腔室的内部，如图1所示，本实施例中隔板6是设置在第一盖1的内部并与第一盖1的侧壁的内壁相配合，但不限于此，事实上将隔板6设置在罐体2的内部与罐体2的内壁相配合也是可以的。调节杆5一端与隔板6相连接，另一端穿过第一盖1上的开孔到达储液器的外部，调节杆5与第一盖1底壁的开孔之间设有螺纹部，转动调节杆5可使得调节杆5相对于第一盖1轴向移动，进而可以带动隔板6在腔室内运动。优选的在调节杆5上设有容积刻度标示51，与内部的实际储液容积相对应，这样操作人员从外部即可清晰的看到内部的容积调节状况，实现容积的准确调节。调节杆5上可设置手动调节机构由手动驱动转动，也可设置驱动机构如电机等驱动。
除了图1中的容积调节部的结构以外，作为另一种较优的实施方式，容积调节部还可以采用由弹性件根据液体的压力自动调节储液容积的结构，如图5中所示，除隔板6外，调节机构可采用包括导向机构和弹性件，其中导向机构可采用导轨12或者滑杆的形式，隔板6上设有与导轨12相适配的卡孔，在所述腔室内使得所述隔板6可沿导轨6移动，所述弹性件可采用弹簧11用于向隔板6施加使隔板6移动的弹性力。这样储液的容积可以根据储存液体的压力进行调整，当液体压力大时，弹簧11被压缩，隔板6被推动使得储液空间变大，当液体压力小时，弹簧11伸展，储液空间变小。
在一个实施例中，罐体2上设有连接支架4，用于罐体2的固定和安装，可以采用焊接或者其他方式相连接。
在一个实施例中，如图1所示，隔板6布置在第一盖1内，并设置在第一盖1的底壁与第一管7之间，这样第一管7不用穿过隔板6进而需要对穿孔处进行额外的密封；当隔板6 布置在罐体2上时，则可采用第一管7穿过隔板6的布置方式。此外，第二管8设置在罐体2上，第二管8连通第一腔室9和外部，通过转动第一盖1可改变第一盖1和罐体2之间的相对位置，进而改变第一管7和第二管8的相对位置，以适应不同的接管的要求。但由于连接支架的位置通常是固定的，所以第二管8的安装位置也会被限定，这种情况下只有第一管7的位置可调节，调节的灵活性还不够强。
为此，作为一种实施方式，罐体2被设计为分体的结构，包括一两端开口的筒体22和一第二盖21，如图1、2所示，第二盖21也具有杯状的结构，包括底壁和侧壁。第二盖21在筒体22的第二开口与筒体22可转动的密封连接以组成罐体2。第一盖1在筒体22的第一开口与筒体22可转动的密封连接。第二盖21与筒体22之间的转动密封结构可以与第一盖1相同或者不同。具体的密封方式同之前的第一盖1与罐体2的密封方式。所述第二盖21上设有连通所述第一腔室9与外部的第二管8，所述第一管7和第二管8的与外部连通的接口的相对位置可随所述第一盖1和第二盖21的相对转动而改变，在本实施例中采用的是将第一管7和第二管8均设置成L形，L形的一部分沿筒体22的轴线延伸，另一部分从第一盖1、第二盖21的侧壁上伸出到外部。为了防止第一盖1和第二盖21在转动时，第一管7和第二管8之间互相干扰的问题，可将第一管7和第二管8的L形部分在筒体22的轴线方向上和径向方向上均错开设置，进而可减少两管的相互干扰。当第一盖1与第二盖21均采用图1中的方式通过螺纹与筒体22连接时，转动第一盖1和/或第二盖21会使得第一盖1和/或第二盖21会沿筒体22的轴向方向有一定量的移动进而使得储液罐的容积发生细微的变化，在需对储液罐的容积进行精确控制的情况下，待将第一盖1和/或第二盖21转动到需要的位置后，应通过调节容积调节部进而对储液部的容积进行调整以将储液罐的容积精确的控制在所需要的容积。
此外，在一个实施例中，为了进一步提高储液器的通用性和连接的便捷性，可将第一管7和第二管8位于所述第一腔室内的管口71和81的高度相同。例如，图1中，在使用状态下，筒体22呈竖起的形状，此时管口71和81具有基本相同的高度，因而不必对第一管和第二管哪根作为进管、哪根作为出管进行区分，便于整机管路连接，即使在转动第一盖1和第二盖21时可能会使得管口71和81的高度发生细微的变化，但这种变化的影响可以忽略不计，进出管可以任意连接，大大提高生产效率。并且使用状态并不限于储液器竖起放置的情况，当储液器横向放置或者采用其他方式放置时，也可针对性的调整第一管7和第二管8的形状和位置，使得管口具有基本相同的高度进而达到同样的效果。
此外，在一个实施例中，为了使第一腔室9在进行容积调节时第二腔室10不会出现压力过高或者压力过低而影响第一腔室9的调节的情况，可在第二腔室10上设置压力调节装置如压力调节阀，或者在第二腔室10上设有小孔，当第二腔室10内压力过低或过高时及时的调整第二腔室10的压力，以使第一腔室9的容积调节能够顺利进行。
此外，需要说明的是第一盖、第二盖、第一腔室、第二腔室、第一管、第二管以及容积调节部的布置位置并不限于图1中所示的命名和位置关系，第一盖与第二盖、第一腔室与第二腔室、第一管与第二管之间均可进行调整，只要能到本发明的技术效果即可。
