The present invention relates to a proportional emulsion valve (1), configured to be used inside a fluid treatment machine, comprising a main body (2) in which an inlet duct (3) is defined, operatively connectable to the hydraulic circuit of a fluid treatment machine and configured to allow the entrance into said valve (1) of a fluid at a pressure higher than atmospheric pressure, and an outlet duct (4) operatively connectable to the hydraulic circuit of the machine and configured for the expulsion of the fluid from the valve (1), the inlet duct (3) and said outlet duct (4) being in fluid communication one another, the valve (1) comprising a slider (7) selectively positionable in an opening position, in which it allows the fluid communication between the inlet duct (3) and the outlet duct (4), and being selectively positionable, against the pressure exerted by a fluid when it is contained in the inlet duct (3), in a closing position in which the fluid communication between the inlet duct (3) and the outlet duct (4) is interrupted due to direct or indirect action of the slider (7), the slider (7) being operatively connected to an actuating system (9) comprising a driving element (10) configured to selectively exercise on the slider (7) a desired closing force (11) which tends to bring it towards the closing position; the driving element (10) is configured to exert the closing force (11) on the slider (7) through an elastic element (12) interposed between the driving element (10) and the slider (7) and configured to elastically force the slider (7) towards the closing position.
Proportional emulsion valve, configured to be used inside a fluid treatment machine, comprising a main body in which an inlet duct is defined, operatively connectable to a hydraulic circuit of a fluid treatment machine and configured to allow entrance into said valve of a fluid at a pressure higher than atmospheric pressure, and an outlet duct operatively connectable to said hydraulic circuit of said machine and configured for expulsion of said fluid from said valve, said inlet duct and said outlet duct being in fluid communication with one another, said valve comprising a slider selectively positionable in an opening position, in which it allows the fluid communication between said inlet duct and said outlet duct, and being selectively positionable, against the pressure exerted by the fluid when it is contained in said inlet duct, in a closing position in which the fluid communication between said inlet duct and said outlet duct is interrupted due to direct or indirect action of said slider, said slider being operatively connected to an actuating system comprising a driving element configured to selectively exercise on said slider a desired closing force which tends to bring it towards said closing position, wherein said driving element is configured to exert said closing force on said slider through an elastic element interposed between said driving element and said slider and configured to elastically force said slider towards said closing position, wherein said slider is configured to move in an alternating linear motion along a longitudinal axis of said slider, and said actuating system comprises a second piston at least partially inserted in said main body and movable with alternating motion with respect to the same, according to the same longitudinal axis as said slider, said driving element being configured to selectively exert said desired closing force on said second piston, said second piston slidingly supporting said slider in such a way that the latter can move in said alternating linear motion with respect to said second piston, said elastic element being interposed between said slider and said second piston in such a way that said closing force is transmitted from said second piston to said slider through said elastic element.
Proportional emulsion valve, configured to be used inside a fluid treatment machine, comprising a main body in which an inlet duct is defined, operatively connectable to a hydraulic circuit of a fluid treatment machine and configured to allow entrance into said valve of a fluid at a pressure higher than atmospheric pressure, and an outlet duct operatively connectable to said hydraulic circuit of said machine and configured for expulsion of said fluid from said valve, said inlet duct and said outlet duct being in fluid communication with one another, said valve comprising a slider selectively positionable in an opening position, in which it allows the fluid communication between said inlet duct and said outlet duct, and being selectively positionable, against the pressure exerted by the fluid when it is contained in said inlet duct, in a closing position in which the fluid communication between said inlet duct and said outlet duct is interrupted due to direct or indirect action of said slider, said slider being operatively connected to an actuating system comprising a driving element configured to selectively exercise on said slider a desired closing force which tends to bring it towards said closing position, wherein said driving element is configured to exert said closing force on said slider through an elastic element interposed between said driving element and said slider and configured to elastically force said slider towards said closing position, wherein said inlet duct and said outlet duct are in fluid communication with one other through a connecting chamber within which said slider is at least partially inserted and movable with alternating motion, through an access opening of said connecting chamber, said valve comprising a gasket, elastically deformable, configured to avoid leakage of fluid from said connecting chamber via said access opening and at the same time to fully wrap a portion of said slider which enters said connecting chamber, elastically deforming until being interposed between said slider and an end of said inlet duct communicating with said connecting chamber, when said slider is in said closing position, so as to watertight close said end, and watertight blocking the passage of fluid from said inlet duct to said connecting chamber.
