摘要: A flow control valve includes a valve body with inlet and outlet ports, and an intermediate chamber therebetween. The valve further includes a static flow rate regulator for the fluid, accessible from outside the valve body and adapted to vary the cross-section of a passage orifice between the inlet and the outlet of the valve. The valve further includes a dynamic flow rate balancer, regulating flow rate based on a change of the incoming flow rate. The flow rate balancer includes a perforated element interposed between the inlet port and the intermediate chamber, allowing fluid passage only through at least one opening of the perforated element and an elastic element at one face of the perforated element facing the inlet port of the fluid into the valve body. An increase in the inlet/outlet differential pressure corresponds to an enlargement of the elastic element, guaranteeing a constant flow rate.

摘要: A metallic pipe connection may comprise a tubular body and a terminal tubular engagement portion configured to be engaged on a pipe and to be fixed thereto by means of plastic deformation of the engagement portion, and a terminal flange on the opposite side of the tubular body with respect to that one provided with the tubular engagement portion. The tubular engagement portion may include an annular seat for a sealing gasket, having a first housing groove for the sealing gasket which may be internally open towards the tubular engagement portion, and at least part of the tubular engagement portion and the annular seat may be plastically deformed such to generate a mechanical seal on the pipe on which the tubular engagement portion is fitted.

摘要: A multiway valve, comprising integrally connected first and second valves. Each valve comprises a valve body comprising a user port, a source port and an intermediate chamber placed therebetween, and a shutter inside the intermediate chamber, having a passage orifice for fluid to pass therethrough. The multiway valve comprises movement means allowing the shutters to move between a closed position where each passage orifice faces the inner walls of the respective intermediate chamber to an open position allowing the passage of the fluid between the user and source ports through the passage orifice. The first valve comprises a bypass duct formed in the shutter opening in fluid communication with the passage orifice. The bypass duct allows fluid communication between the intermediate chamber, the passage orifice, the duct, and the user and source ports of the first valve when the shutter is in its closed position.
