\nTVN V206 Clapet Axial \u00e0 Brides, \u00e9galement connus sous le nom de clapets anti-retour anti-claquement et clapets anti-retour \u00e0 ressort r\u00e9duisent ou \u00e9liminent les coups de clapet et leurs effets.<\/p>\n

Le coup de b\u00e9lier fait r\u00e9f\u00e9rence aux ondes de choc \u00e0 haute pression qui se produisent lorsque le d\u00e9bit de fluide s’arr\u00eate brusquement (en raison de l’arr\u00eat de la pompe ou de la fermeture rapide d’un papillon de vanne) dans un syst\u00e8me de tuyauterie. Lorsque des coups de clapet se produisent, l’inversion de d\u00e9bit qui en r\u00e9sulte exerce une pression importante sur le tuyau, mettant en danger son int\u00e9grit\u00e9 structurelle et l’ouvrant \u00e0 une rupture et des d\u00e9g\u00e2ts potentiels. Les clapets anti-retour \u00e0 battant, les clapets anti-retour \u00e0 disque inclinable et les clapets anti-retour \u00e0 double porte, entre autres, contribuent souvent aux probl\u00e8mes de coups de clapet.<\/p>\n

Pour contr\u00f4ler les coups de clapet et le reflux, l’utilisation de clapets anti-retour silencieux est recommand\u00e9e. Lorsque la source en mouvement, le fluide s’arr\u00eate et que le flux vers l’avant du fluide diminue, l’action du ressort en inox sp\u00e9cialement con\u00e7ue du va-et-vient silencieux contr\u00f4le la fermeture du papillon de vanne avant le renversement du d\u00e9bit. Cette assistance par ressort garantit que la vanne ne se ferme pas et que l’apparition de coups de clapet est \u00e9limin\u00e9e.<\/p>\n

      Axial Silent Check Valve Product Features<\/h2>\n
        \n
      1. <\/i><\/span>Streamlined flow path through full-port expanded body avoids turbulence and prevents erosion and vibration. Process downtime and maintenance costs are eliminated.<\/li>\n
      2. <\/i><\/span>The full opening flow passage and high-pressure recovery of the venturi-shaped body result in very low pressure loss: reduced operating cost of pumps and compressors.<\/li>\n
      3. <\/i><\/span>The stability of a compressor system during startup benefits from a low cracking pressure. This is achieved with a large disc that has identical effective pressure areas on both sides (line contact sealing).<\/li>\n
      4. <\/i><\/span>The spring-assisted design ensures ultra-fast closing with virtually no back flow and pressure surges in critical applications such as multi-pump systems or LNG trains.<\/li>\n
      5. <\/i><\/span>Internal construction is based on the application of sound basic mechanical engineering principles. Consequently axial check valves do not require any maintenance.<\/li>\n
      6. <\/i><\/span>Both the pressure drop and the dynamic behavior can be predicted with great accuracy, based on full-scale laboratory flow tests and a mathematical model developed in cooperation with a recognized fluid hydraulics laboratory.<\/li>\n
      7. <\/i><\/span>Hydrostatic test pressure for seat: PN x 1.1 , for shell: PN x 1.5 according to EN 12266-1.<\/li>\n<\/ol>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
