ES284136U - Piston valve for fluids and gases (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Piston valve for fluids and/or gases, of the type constituted by a valve body inside which are two lateral chambers terminated in their free end zones by means of coupling to the corresponding conduit, in the center of which the valve body presents a axial cylindrical passage that connects the chambers, and said step is topped by a widening opposite and like another end that presents the press-tow in which is coupled in axial direction a spindle related to the piston and driven by a steering wheel ; characterized in that the valve body internally has sealing elements constituted by a lower closing ring suitably positioned in its housing and a closing ring to the outside or environment being positioned between both rings a separating element located between the two chambers, whose separator allows, where appropriate, the passage of the fluid in open valve position, circulating the fluid through both chambers without turbulence by the effect of specially formed ribs that form internal passages for the fluid; while the steering wheel presents centrally a skirt dimensioned to protect the spindle that allows to check the closing or opening state of the valve; and a press-tow that transmits to the sealing elements, the pressure being transformed into radial with a concentric uniformity on the piston.
