A dosage valve (1) for transferring liquids with increased practicality of use, which comprises a main body (2) that defines a duct (3) for the passage of a liquid to be transferred between a first opening (4), intended to be connected with a fluid connection to the mouth of a first tank for the storage of the liquid and a second opening (5) intended to be connected with a fluid connection to the mouth of a second tank into which the liquid is to be transferred. The valve (1) further comprises a first flow control element (14) arranged so that it can move along the passage duct (3) between an open configuration and a closed configuration in which it allows and interrupts, respectively, the connection between the first and second openings and first means for actuation (15) of the movement of the first flow control element (14) between such open and closed configurations. The valve (1) comprises, further, an element (16) for piercing a protective film applied on the mouth of the first tank, which is supported by the main body (2) proximate to the first opening (4) and can move along the passage duct (3) between an inactive configuration, in which it is accommodated along the duct, and an active configuration, in which it protrudes at least partially from the first opening (4), and second means for actuation (17) of the movement of the piercing element (16) between such inactive and active configurations. The first and second actuation means (15, 17) are integrated in a single element (18) for rotational actuation about a rotation axis (A) that is transverse to the extension of the passage duct (3) of a cam (19) that is supported by the main body (2) within the duct and is coupled to a tappet (20) that supports the first flow control element (14) and the piercing element (16). Such tappet (20) can move alternately along the passage duct (3) between a first position, in which the piercing element (16) is in the active configuration and the first flow control element (14) is in the open configuration, and a second position, in which the piercing element (16) is in the inactive configuration and the first flow control element (14) is in the closed configuration. |
