Abstract

Double adjustment valve for heating radiators, characterized essentially because it is constituted by a general body with two lower mouths, one inlet and one outlet, as well as two lateral mouths, one connected to the radiator and another in which it is mounted by threaded an intermediate body that defines with the general body a constant intercommunication chamber between the inlet and outlet, being internally coupled in this second body a shutter element operated externally by a hand wheel to close the outside by a handwheel to close the passage of the fluid to the radiator or to derive the liquid towards it through the lateral mouth, while maintaining the intercommunication between lower mouths, having an axial screw for limiting the maximum displacement of the frontally regulated obturator; in said lateral mouth of communication with the radiator, two tubes are mounted axially arranged and joined together and secured to respective support washers, the tubes defining two communications with the radiator, one of fluid flow on the outside of the tubes and another return on the inside, returning the liquid to the outlet mouth through windows or holes provided in the sealing element and intermediate body which in the position of opening of the shutter communicate with each other.
