本实用新型涉及食品、药品包装机械设备技术领域，尤其涉及一种灌装装置。
吹灌封技术为一种无菌封装技术，该设备通常一次可生产数十支（10~60）产品，由于灌装头数较多，并为了实现CIP（清洗）和SIP（消毒），通常采用的是时间压力法灌装，即在一定的灌装压力下，通过控制灌装阀的开启时间来控制装量。

1）灌装段为竖直的直通段，回吸通道的两端与灌装段倾斜连接，在清洗过程中，清洗液更容易从灌装段直流而下，很少的清洗液才能流至回吸通道中，造成对回吸通道的清洗效果差；
2）节流阀和计量阀分别位于上游座和下游座上，占用空间大，且加工不方便。
本实用新型要解决的技术问题是克服现有技术的不足，提供一种结构简单以及能够提高清洗效果的灌装装置。
为解决上述技术问题，本实用新型采用以下技术方案：

所述节流阀、计量阀和回吸阀均为膜片阀，各阀的膜片均夹设于上游座和下游座与侧座的拼接处。

所述供液机构包括主通道和多个与主通道连通的支通道，所述灌装通道设有多个，与支通道一一对应连通。
与现有技术相比，本实用新型的优点在于：

图1至图3示出了本实用新型灌装装置的一种实施例，本灌装装置包括供液机构1、回吸机构5和与供液机构1连通的灌装通道2，灌装通道2包括依次连接的节流段21、计量段22和灌装段23，回吸机构5包括回吸通道51和回吸阀52，回吸通道51的一端与灌装段23的中部连接，另一端设有延伸段24，灌装段23的底端与延伸段24连通，延伸段24的底端连通有出液端25，回吸阀52设于回吸通道51上，节流段21与供液机构1连通，节流段21设有节流部6，计量段22设有计量部7。
灌装时，回吸阀52关闭，计量阀4打开，灌装完成后，关闭计量阀4，然后打开回吸阀52，实现回吸，防止灌针挂滴，然后在下次打开计量阀4之前或同时先关闭回吸阀52。清洗时，计量阀4、回吸阀52均完全打开，以加大清洗液的流量，提高对灌装通道2和回吸通道51的清洗效果。灭菌时，计量阀4、回吸阀52均完全打开，各阀与灌装通道2的配合部均被消毒灭菌，提高灭菌效果。节流部6设于计量阀4的上游，有节流存在压差，计量阀4设于回吸机构5的上游，压力通过计量阀4阻断，不对回吸产生影响。
本灌装装置，灌装段23通过延伸段24与出液端25连接，灌装段23和出液端25没有直通连接，避免在清洗过程灌装段23中的清洗液直流至出液端25，在延伸段24的阻挡作用下，更多的清洗液能流至回吸通道51中，提高了对回吸通道51的清洗效果差，从而提高了整体清洗效果。
本实施例中，回吸通道51呈V字形，回吸阀52设于回吸通道51的尖角处。清洗时，打开回吸阀52，使清洗液能够进入回吸通道51，清洗干净回吸通道51。
本实施例中，节流部6呈V字形，节流部6的尖角处设有节流阀3。节流部6呈V字形设置，便于装设节流阀3。
本实施例中，节流部6的尖角处还设有并联通道61。灌装时，可将节流阀3完全关闭，灌装介质通过并联通道61流动。这样，节流点在灌装时不变动，灌装过程更稳定。并且，计量阀4、计量阀4和开回吸阀52竖向间隔布置，节流在上端，没有压差影响，滴液风险更低。
本实施例中，计量部7均呈V字形，计量部7的尖角处设有计量阀4。计量部7呈V字形设置，便于装设计量阀4。
本实施例中，如图2所示，灌装装置还包括相拼合的上游座8和下游座9以及拼合于上游座8和下游座9一侧的侧座91，节流段21和计量段22设于上游座8中，节流部6和计量部7的尖角处均位于上游座8与侧座91的拼接处，灌装段23、延伸段24和出液端25贯穿于下游座9中，且灌装段23的顶端延伸至上游座8中，回吸通道51的尖角处均位于下游座9与侧座91的拼接处，节流阀3、计量阀4和回吸阀52均安装在侧座91上。
节流段21、计量部7和回吸通道51的尖角处均位于下游座9与侧座91的拼接处，节流阀3、计量阀4和回吸阀52均安装在侧座91上，并分别与节流段21、计量部7和回吸通道51的尖角处配合连接，这样，在安装时，只需要先将节流阀3、计量阀4和回吸阀52安装在侧座91上，再将侧座91与上游座8和下游座9拼合即可。具体地，上游座8和下游座9上下设置。
节流阀3与计量阀4都位于上游座8上，可有效节省空间，便于加工。并且，灌装段23的顶端延伸至上游座8中，使其下部分在下游座9中，上部分在上游座8中，这样，便于分开加工及对接。
本实施例中，节流阀3、计量阀4和回吸阀52均为膜片阀，各阀的膜片92均夹设于上游座8和下游座9与侧座91的拼接处。这样，各阀的膜片92可以独立设置，也可以整体设置。
本实施例中，灌装段23和出液端25均与膜片92平行，且灌装段23离膜片92的距离比出液端25离膜片92的距离近。延伸段24的底端向出液端25方向倾斜设置，灌装段23离膜片92的距离小于灌装段23直径的三倍，得回吸通道51更易清洗。
本实施例中，供液机构1包括主通道11和多个与主通道11连通的支通道12，灌装通道2设有多个，与支通道12一一对应连通。通过多个灌装通道2进行灌装，提高灌装效率。
节流部6的尖角处设有并联通道61。并联通道61呈V字形设置，且并联通道61设置成比灌装通道2小，以减少在灌装时的流量。这样，各灌装通道2灌装时，通过各并联通道61的介质流量更加均匀，灌装过程更稳定，精装精度更高。
虽然本实用新型已以较佳实施例揭示如上，然而并非用以限定本实用新型。任何熟悉本领域的技术人员，在不脱离本实用新型技术方案范围的情况下，都可利用上述揭示的技术内容对本实用新型技术方案做出许多可能的变动和修饰，或修改为等同变化的等效实施例。因此，凡是未脱离本实用新型技术方案的内容，依据本实用新型技术实质对以上实施例所做的任何简单修改、等同变化及修饰，均应落在本实用新型技术方案保护的范围内。。
