Abstract:
A safety device for taps for pasteurizing tanks comprising a disk shutter, a tubular sector shaped like the arc of a circle communicating with said pasteurizing tank, said tubular sector being provided with a radial outlet, an operating lever connected to said shutter for moving said shutter along said tubular sector, a spring pin on said lever, a semi-circular element provided with a number of hollows cooperating with said pin, the semi-circular element being concentric with respect to the rotation axis of said operating lever, so that by lifting said pin from said hollows the said operating lever can be freely rotated around its hinging axis, thus sliding the shutter disk within said tubular sector from a position in which it closes up the communication between said tubular sector and the said pasteurizing tank, to an intermediate position in which the said radial outlet become opened, and further to a position in which it is completely taken out of the said tubular sector, wherein cooperating abutment means are provided both on the said operating lever and in the said semi-circular element provided with the said hollows defining the said positions of said operating lever of the said shutter, so as to stop the movement of the said operating lever on reaching said intermediate position in which said radial outlet for product discharge become opened.
