Definitions

  • the present invention relates to a valve for pipelines for transporting fluids.
  • valve finds useful application within a pipeline for distributing pressurised fluids, such as aqueducts, gas pipelines, fire-fighting systems, civil and 5 industrial systems for supplying pressurised liquids or gas, etcetera.
  • pressurised fluids such as aqueducts, gas pipelines, fire-fighting systems, civil and 5 industrial systems for supplying pressurised liquids or gas, etcetera.
  • the invention particularly relates to a valve comprising a main body, provided with at least an inlet and with at least an outlet, and a regulating device, supported by the main body, able to regulate the passage of fluid between the inlet and the outlet.
  • the valve is interposed between at least two pressurised conduits of the i o distribution pipeline, with the task of regulating the passage of the fluid between the conduits.
  • Known valves of this type are generally made of a metallic material, for
  • valves 15 instance bronze and brass, steel, cast iron, etcetera.
  • coupling of the valve to the pressurised conduits of the distribution pipeline is obtained by means of flanges, projecting from the main body of the valve, which are fastened, through screw connections, to flanges integral with the conduits.
  • the aim of the present invention is to obtain a constructively simple and economical valve that is able to overcome the aforesaid limits and drawbacks of the prior art.
  • An advantage of the subject invention is to provide a valve which can be connected to the pipes of a distribution pipeline in an extremely simple and rapid manner, in particular without the need for a metal flange and/or a collection sump.
  • Another advantage is to allow a connection, between a valve and the related pressurised pipes of the pipeline, that is provided with a high mechanical resistance against the stresses of the pipeline itself and with a considerable sealing capacity with respect to the transported fluid.
  • Yet a further advantage is to make available a valve that is able to assure the stability and coaxial condition of the connection with the pipes of a distribution pipeline.
  • Other advantages of the subject invention are as follows: minimising the wastage and leaks in transporting a pressurised fluid; reducing the operation and maintenance costs of a pipeline for the distribution of a pressurised fluid; increasing the reliability and safety of the distribution pipeline.
  • FIG. 1 shows a schematic, partially sectioned, view of a vale obtained in accordance with the present invention.
  • the reference number 1 globally indicates a valve destined to regulate the passage of a pressurised fluid in correspondence with a node of a pipeline for distributing the fluid.
  • a valve is shown with an inlet and an outlet for regulating the flow rate of the fluid to be sent to one or more users downstream of the valve.
  • the valve 1 comprises a main body 2, made of metallic material, provided with at least an inlet 3 and with at least an outlet 4.
  • the main body 2 supports a regulating device 5 which serves to regulate the passage of fluid between the inlet 3 and the outlet 4.
  • the regulating device 5 comprises a stem, rotatorily coupled about an axis of rotation x-x, in a sealed manner, within the main body 2 and extending to its exterior, and an organ 7 for intercepting the fluid, inside the main body 2, movable with the stem 6 to vary the communication port between the inlet 3 and the outlet 4.
  • the protective structure 8 is obtained in a single body by plastic material casting.
  • the structure 8 presents, on opposite sides, two planar end faces, each whereof is substantially coplanar to the inlet 3 and, respectively, to the outlet 4.
  • the part of stem 6 that extends outside the main body is at least partially covered and buried by the protective structure 8.
  • Said conduits 9 and 10 have provisions for connection, by means of respective known quick coupling organs 1 1 and 12, to the conduits of the pipeline for the distribution of the pressurised fluid, constituted by a pipeline 13 for supplying the fluid and, respectively, by a pipeline 14 for using the fluid.
  • the inlet conduit 9 and the outlet conduit 10 are both joined, at opposite sides, to the protective structure 8 through a stable connection, preferably by means of gluing, for instance, with silicone rubber.
  • the gluing material forms, for every conduits 9 and 10, an annular gasket 16, coaxial to the longitudinal axis y-y of the valve 1 , and able to provide a seal in correspondence with the inlet 3 or with the outlet 4.
  • the method for installing the valve 1 comprises, for each conduit 9 and 10, the phases of screwing the conduit 9 and 10 to the respective outlet 3 and 4 and then joining, preferably by gluing, the conduit 9 and 10 to the protective structure 8, so that the gluing material constitutes the gaskets 16.
  • This type of union in addition to being nearly immediately accomplished even in situations that normally require laborious operations, offers considerable guarantees in terms of its seal and safety, even for pipeline pressures that are high and subject to abrupt variations.
  • valve can be connected to the pipes of a pipeline for distributing a pressurised fluid in an extremely simple, rapid manner, in particular with no need for a metal flange and/or a collection sump.
  • connection thus obtained has high mechanical resistance to the stresses of the pressurised pipeline and a considerable sealing capacity with respect to the transported fluid. Numerous other practical-applicative modifications can be applied to the constructive details of the invention, without thereby departing from the scope of protection of the inventive idea claimed below.

Abstract

L'invention concerne une soupape pour canalisations destinées à transporter des liquides, comprenant un dispositif de régulation (5) soutenu par un corps principal (2), permettant de réguler le passage du liquide entre une entrée (3) et une sortie (4) portées par le corps lui-même. Une structure (8) de protection, constituée d'un matériau plastique, recouvre et enterre au moins la quasi-totalité du corps principal (2) et au moins une partie du dispositif (5) de régulation. Des canalisations d'admission (9) et de sortie (10), accouplées par vissage à l'entrée et à la sortie, présentent des organes (11, 12) à connexion rapide pouvant être reliés à une canalisation d'alimentation (13) et une canalisation d'utilisation (14) de la ligne de distribution. On obtient deux joints annulaires (16) par la distribution d'un matériau de collage en correspondance de l'entrée et de la sortie.
