摘要： A connecting structure for an integration panel and a fluid device in which an excellent sealing property can be held even when substantially no further fastening is performed, and the assembling workability is improved is provided. When an integration panel 1 and a valve 2 are to be communicatingly connected to each other in a sealed state through single circular pipe-like fluid passages 3, 7 by using an annular gasket G, annular projections 11, 21 are formed in first and second fluid supply/discharge port portions 1A, 2A, the gasket G is configured by a fluororesin having a pair of annular grooves 51, 51 which are formed in an outer-diameter portion of a fluid path W to be fitted to the annular projections 11, 21, respectively, and holding means I for holding a joined state is equipped. In the joined state, the integration panel 1 and the valve 2 are attracted to each other, and the annular projections 11, 21 of the first and second fluid supply/discharge port portions 1A, 2A are fitted respectively to the annular grooves 51 of the gasket G to form a fitting sealing portion.

摘要： It is an object of the invention to, even in the case where transported liquid containing a sedimenting material such as slurry is used, prevent the sedimenting material from stagnating and collecting in an extending and contracting portion of a bellows. In order to attain the object, a bellows 7 that is extendingly and contractingly deformable in the axial direction is placed in a pump body 1 with setting the axis B of the bellows vertical so as to be driven to perform extending and contracting deformation, and form a liquid chamber 9 inside the bellows 7. A suction port 18 and a discharge port 19 are formed in an inner bottom face 4a of the pump body 1 facing the liquid chamber 9. Liquid is sucked from the suction port 18 into the liquid chamber 9 by extension of the bellows 7, and the liquid in the liquid chamber 9 is discharged from the discharge port 1 by contraction of the bellows 7. The extending and contracting portion of the bellows 7 which is configured by forming ridge-like folds 71 and valley-like folds 72 in a vertically alternate and continuous manner is formed into a shape in which the lower one of upper and lower lamella portions 71a and 71b of each of the ridge-like folds 71, or the lower lamella portion 71b is downward inclined as moving toward the axis B, not only in an extending state but also in a contracting state. Even in the case where liquid containing a sedimenting material such as slurry is used, therefore, the sedimenting material can be prevented from sedimenting and stagnating in the extending and contracting portion of the bellows 7.
摘要翻译：本发明的目的在于，即使在使用含有泥浆等沉降材料的输送液体的情况下，也能够防止沉降材料滞留并收集到波纹管的伸缩部。为了实现该目的，通过将波纹管的轴线B设置成竖直从而被驱动以执行伸缩变形，将能够在轴向方向上伸缩地收缩变形的波纹管7放置在泵体1中，并且形成一个位于波纹管7内部的液体室9.一个吸入口18和一个排出口19形成在泵体1的面向液体室9的内底面4a中。液体从吸入口18吸入液体室9 通过波纹管7的延伸，液体室9中的液体通过波纹管7的收缩而从排出口1排出。波纹管7的延伸和收缩部分通过形成脊状褶皱71和谷部垂直交替且连续的方式形成的褶皱72形成为这样的形状：其中，每个脊状褶皱71或下部片层部分71b的上部和下部薄片部分71a和71b中的下部片层部分71a和71b处于向下 d随着朝向轴线B移动而倾斜，不仅处于伸展状态，而且处于收缩状态。因此，即使在使用含有泥浆等沉降材料的液体的情况下，也能够防止沉降材料在波纹管7的伸缩部分沉降滞留。
