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.

Provided is a valve (12), including an in-line flow passage (44), a shutoff mechanism (16), and a multi-stage throttling section (26) disposed in the in-line flow passage (44). Further provided is an in-line valve (12), including a flow control component (26) and a sealing component (16), wherein the flow control component (26) and the sealing component (16) are separate from one another.
摘要:
A check valve (40) comprising a hollow body (38), extending around a body axis (D) so as to delimit internally a body cavity (70) for the crossing of a fluid and comprising an annular abutment bead (44) projecting radially into the cavity, and a mobile obturator (42), housed at least partially in the body cavity (70) and susceptible to be reversibly moved by the transit of the fluid between an interception configuration wherein said obturator sealingly lies on the annular abutment bead (44), and a transit configuration of the fluid, wherein the mobile obturator is distanced from the bead. Moreover, the hollow body (38) and the annular abutment bead (44) are joined to each other without fluidic sealing elements.
摘要:
A jet regulator (1), having a perforated plate (5) arranged inside the jet controller and flow-through holes (6) extending through the perforated plate for dividing the water flowing through, comprises a central, hole-free impingement surface (14) on the perforated plate (5), which hole-free impingement surface is surrounded by a first ring wall (15), which has passage openings (16) that are oriented in a radial direction and extend through the first annular wall, wherein a respective flow-through hole (6), which extends through the perforated plate (5) and is connected to the respective passage opening (16), is provided on the side of each passage opening (16) arranged in the impingement surface plane. The ring wall (15) is surrounded by an annular ring chamber (29) on the outer circumferential side. A flow regulator (30) or a throttling device (300) is provided in front of the impingement surface (14) in the flow direction of the water, whereby the water consumption is restricted and/or the water flow rate becomes largely independent of the particular water pressure. Furthermore, a second ring wall (33), which has a smaller diameter than the first ring wall and is arranged at a distance from the first ring wall, is provided coaxially and concentrically to the first ring wall (15), which second ring wall has radial passage openings (34) arranged at a distance above the impingement surface (14), through which radial passage openings the water has access to the first ring wall (15) and to the passage openings (16) of the first ring wall and thus to the flow-through holes (6). By means of this combination, the water flow rate through the jet regulator becomes practically independent of the water pressure upstream of the jet regulator (1).
摘要:
In the case of a sanitary fixture (1), it is proposed that at least one covering surface (7), by way of which at least one flow opening (4) of a flow element (3) is openable and at least partially closable in a temperature-dependent manner, be formed on a covering element (6) made of a temperature-sensitive material (cf. figure 1).
