| 摘要 |
This invention relates to a flexible membrane separation valve, comprising a housing (120), the lateral surfaces of which are provided with slits (121), within which housing (120) a flexible membrane (122) with cylindrical symmetry is housed, within which an insert (130) having a body (131) with cylindrical symmetry is in turn housed, the insert (130) comprising a proximal end (132) having a proximal apex (133) spaced along the longitudinal axis of the insert (130) from a base (134) with cylindrical symmetry, through which the proximal end (132) joins to the body (131), the proximal apex (133) being joined to the base (134) through a continuous surface, the valve being characterized in that the proximal end (132) has an axial section such that tangent lines to the proximal apex (133) form an angle containing the longitudinal axis of the insert that is lower than or equal to 90°. The invention further relates to an apparatus for mixing a liquid comprising such a flexible membrane separation valve. |
