On l&#039;appelle \u00e9galement clapet anti-retour, clapet anti-retour, clapet anti-retour et clapet anti-retour. Sa fonction principale est d&#039;emp\u00eacher le fluide de refluer, d&#039;emp\u00eacher la pompe et le moteur d&#039;entra\u00eenement de s&#039;inverser et de d\u00e9charger le fluide du conteneur. Les clapets anti-retour peuvent \u00e9galement \u00eatre utilis\u00e9s pour alimenter les canalisations des syst\u00e8mes auxiliaires o\u00f9 la pression peut d\u00e9passer la pression du syst\u00e8me.<\/p>\n\n\n\n<!-- Andy:h-related-tags -->\n<h2 id=\"h-related-tags\">Balises associ\u00e9es :<\/h2>\n<!-- \/Andy:h-related-tags -->\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/fr\/\">Soupape ZECO<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/fr\/difference-between-gate-valve-and-butterfly-valve.html\/\">Diff\u00e9rence entre la vanne \u00e0 vanne et la vanne papillon<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/fr\/gate-valve-problems.html\/\">R\u00e9paration de vannes \u00e0 vanne<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/fr\/advantages-and-disadvantages-of-globe-valves.html\/\">Qu'est-ce qu'un robinet \u00e0 soupape ?<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/fr\/difference-between-gate-valves-and-ball-valves.html\/\">Vanne et robinet \u00e0 boisseau sph\u00e9rique<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/fr\/what-is-an-axial-flow-silent-check-valve.html\/\">Qu'est-ce qu'un clapet anti-retour axial ?<\/a>\n\n<\/div>\n\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/fr\/produit\/manual-gate-valve\/\">Fabricant de robinets-vannes \u00e0 commande manuelle<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/fr\/the-function-of-globe-valve-in-pipeline-system.html\/\">Que sont les vannes \u00e0 soupape\u00a0?<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/fr\/tag\/shanghai-pressure-reducing-valve-factory\/\">Usine de soupapes de r\u00e9duction de pression de Shanghai<\/a>\n\n<\/div>","protected":false},"excerpt":{"rendered":"<p>\u2160.
