Abstract:
A rotatable bleeding valve for heating installations, comprising an external body (1), a cover (3), a float (11) with an inclined plane (13) acting on a stem (15) of a shutter (17), a cylindrical spring (25), intended to keep said shutter (17) closed, and a cap (27) on the cover (3), wherein the wall of the external body (1), with a smooth upper end (31), has a threated toroidal projection (33), onto which a corresponding threated projection (35), in the lower end of cover (3) is secured; and wherein said cover (3) has its lower portion (37) shaped with an arc-shaped cavity (39) and a beat (40) which rests against the upper edge (31) of the cylindrical body (1); the gasket (9), pressed between said two walls (31, 39), occupying the space between them and providing anyway a seal.
Abstract:
The valve according to the invention comprises an outer body (1) wherein a fluid flow duct (C) is made, a rotary closing member suitable for closing or opening the duct (C), a locking pin, a safety device through which, with a removable key (5), the locking pin can be operated; the latter is arranged substantially by side of the rotary closing member (2) and is suitable for moving relative to the rest of the valve so as to block and unblock or limit the rotation of the rotary closing member, at least with a displacement component parallel to the predetermined rotation axis (AR); this way valves can be made provided with safety systems substantially simple and robust, and suitable for preventing unauthorized uses of the valve, by largely using -with slight adaptations, if any- components of pre-existing valves.
Abstract:
The driving system according to the invention comprises a motor-driven actuator (1), a valve (2) and a joint (3') connecting them. The joint (3') includes a connecting shaft (50') having a hole (506) arranged to receive the end of a lever (6'). By inserting the lever (6') into the passage left open by the opening (320) and the hole (506), the connecting shaft (50') is disconnected from the actuator (1) and the stopper (280) of the valve (2) can be manually rotated without damaging the actuator itself. When not in use, the lever (6') can be removed from the hole (6') so that the lever does not create dangers. The invention further concerns the joint (3) connecting the actuator (1) and the valve (2), and the kit for supplying the lever (6') along with the joint (3) and possibly the valve (2) or the actuator (1).
Abstract:
The invention relates to a valve body (10) comprising: an inlet duct (12) having an inlet opening (18) capable of receiving a flow of fluid, and a housing portion (20) for a valve (22); an intermediate duct (14) connected downstream from the inlet duct (12) has a housing portion (24) for a filter element (26). The outlet duct (16) is connected downstream of the intermediate duct (14) and has an outlet opening (28) capable of delivering the flow of fluid to the exterior, and a housing portion (30) for an outlet valve (32). The inlet valve (12) also extends along an inlet axis (X-X), while the outlet duct (16) extends along an outlet axis (Y-Y) which is different from the inlet axis (X-X) and the intermediate duct (14) extends along an intermediate axis (Z-Z) which is transverse to the inlet axis (X-X) and the outlet axis (Y-Y).
Abstract:
Unit for distributing fluids (10, 10a, 10b), comprising a main housing (12) which encloses within itself a supply pipe (14) comprising an inflow segment (20) arranged to be connected, at its inlet, to a pressurized sanitary water source and a first distribution segment (22) intended to deliver cold sanitary water; a sanitary heated water supply pipe (11) comprising a second inflow segment (27) arranged to be connected, at its inlet, with a source of heated sanitary water under pressure and a second distribution segment (24) intended to deliver heated sanitary water; a heating circuit (16) comprising a delivery segment (28) arranged for being hydraulically connected, at its inlet, to a pressurized heat carrier fluid source, and a return segment (30) arranged for being hydraulically connected, at its outlet, to the heat carrier fluid source; an inner housing (26) made of thermally insulating material and enclosed within said main housing (12); said inner housing (26) enclosing within itself said sanitary heated water supply pipe (11) and said heating circuit (16), while leaving outside said first distribution segment (22) and at least the portion of said inflow segment (20) which is located upstream of said first distribution segment (22); said unit (10, 10a, 10b) further comprising a recirculation circuit (71) with a regulator valve (72) connected, at its inlet, to the second inflow segment (27) and hydraulically connected, at its outlet, to the pressurized heat carrier fluid source.
Abstract:
The unit for distributing fluids (10) comprises a main housing (12), internally enclosing: a supply pipe (14) comprising an inflow segment (20) arranged to be connected, at its inlet, with a pressurised sanitary water source, a first distribution segment (22) intended to provide cold sanitary water, and a second distribution segment (24) intended to provide heated sanitary water; a heating circuit (16) arranged to be connected with a source of pressurised heat carrier fluid; and heat exchange means (18) connected to the supply pipe (14) and the heating circuit (16) so as to allow a heat transfer from the heating circuit (16) to the supply pipe (14). The unit (10) further comprises an inner housing (26) made of thermally insulating material and enclosed within the main housing (12). The inner housing (26) internally encloses the heating circuit (16), the heat exchange means (18) and the second distribution segment (24), while leaving outside the first distribution segment (22) and the portion of the inflow segment (20) which is located upstream of the first distribution segment (22).
Abstract:
The present invention relates to a manifold for fluids (10) comprising quick action elements, male- (15) or female (16), wherein one of such elements, in particular the female element (16), comprises an annular protecting shell (33) arranged so as to protect the coupling male element from tampering or damages after the coupling is assembled Since the manifold (10) has a simple structure, can be made either of plastic- or of metallic material.

Abstract:
An actuator (1) is fixed on a valve (2) through a fixing joint (3) which comprises a tubular sleeve (32) on which a tightening nut (30) is screwed; the nut (30) and the sleeve (32) are provided with a conical thread connection (34, 300); by screwing the nut (30), a plurality of longitudinal prolongations (40), arranged in a crown around the axis of the sleeve (32), tightens on a fixing head (20) of the valve (2), firmly fixing the actuator (1) to the valve (2); the joint at issue provides an alternative to a flange connection, equally solid and resistant to unscrewing due to vibrations; by resting against a mechanical stop surface (24) the nut (30), being unscrewed, can act as an extractor that easily removes the joint (3) from the head (20).
