Quelles sont les causes du blocage Soupape \u00e0 bille<\/a><\/mark><\/strong>?<\/h2>\r\n\r\n\r\n\r\n\r\nL'un des types les plus courants de d\u00e9faillance des vannes \u00e0 bille implique une accumulation de salet\u00e9 et de s\u00e9diments \u00e0 l'int\u00e9rieur de la vanne, ce qui rend son ouverture et sa fermeture difficiles. L'utilisation de colle \u00e0 base de solvant peut \u00e9galement obstruer la bille, la faisant coller \u00e0 l'int\u00e9rieur de la valve et l'emp\u00eacher de tourner. Si cela se produit, vous devrez d\u00e9monter la valve et nettoyer toute salet\u00e9 que vous voyez.\r\n\r\n\r\n\r\n\r\n\r\nUne autre d\u00e9faillance fr\u00e9quente des vannes \u00e0 bille se produit lorsque l'\u00e9lastique utilis\u00e9 pour sceller la vanne (souvent sous la forme d'un joint torique) s'use avec le temps en raison du liquide ou du gaz qui y est pouss\u00e9. Puisqu'il s'agit d'un sympt\u00f4me naturel d'utilisation, vous souhaiterez remplacer l'\u00e9lastique lorsque vous remarquerez des fissures ou des fuites. R\u00e9duire l'intensit\u00e9 du liquide circulant \u00e0 travers la vanne peut \u00e9galement contribuer \u00e0 prolonger la dur\u00e9e de vie du joint torique.\r\n\r\n\r\n\r\n\r\n\r\nAu fur et \u00e0 mesure que l'\u00e9lastique commence \u00e0 se d\u00e9placer, la garniture int\u00e9rieure de la tige de valve fait \u00e9galement de m\u00eame. Toute rayure ou tout dommage \u00e0 la tige de valve n\u00e9cessite que quelqu'un remplace la tige ou la valve enti\u00e8re avant que l'ensemble ne s'effondre.\r\n\r\n\r\n\r\n\r\n\r\nAssurez-vous \u00e9galement de rechercher des points de fuite au niveau des \u00e9crous retenant les boulons. Cela indique que les \u00e9crous sont trop desserr\u00e9s ou que le connecteur d'extr\u00e9mit\u00e9 doit \u00eatre r\u00e9align\u00e9. Les dommages aux joints toriques autour des \u00e9crous peuvent \u00e9galement \u00eatre \u00e0 l\u2019origine de ces fuites.\r\n\r\n\r\n\r\n\r\n

Comment ouvrir un robinet \u00e0 tournant sph\u00e9rique bloqu\u00e9 ?<\/h2>\r\n\r\n\r\n\r\n\r\nLes robinets \u00e0 tournant sph\u00e9rique sont des vannes couramment utilis\u00e9es pour l'eau principale et divers arr\u00eats de branchement. Cette vanne fonctionne comme une vanne ON\/OFF, ce qui signifie que la vanne doit \u00eatre soit compl\u00e8tement ouverte, permettant le plein d\u00e9bit, soit compl\u00e8tement ferm\u00e9e, arr\u00eatant tout le d\u00e9bit d'eau. Parfois, il peut \u00eatre n\u00e9cessaire de desserrer un robinet \u00e0 tournant sph\u00e9rique parce qu'il est coinc\u00e9 ou serr\u00e9, cr\u00e9ant ainsi une obstruction \u00e0 l'\u00e9coulement du fluide. Si un robinet \u00e0 tournant sph\u00e9rique ne s'ouvre pas, suivez les \u00e9tapes suivantes pour r\u00e9soudre le probl\u00e8me\u00a0:\r\n\r\n\r\n\r\n\r\n
    \r\n \t
  1. Op\u00e9ration manuelle<\/li>\r\n \t
  2. Coupez l\u2019alimentation en eau principale.<\/li>\r\n \t
  3. Ensuite, desserrez la valve en l'ouvrant et en la fermant plusieurs fois en tournant sa poign\u00e9e.<\/li>\r\n \t
  4. Frappez doucement le corps de la vanne plusieurs fois sur le corps de la vanne pour briser et lib\u00e9rer les particules emprisonn\u00e9es entre la bille et le corps de la vanne.<\/li>\r\n \t
  5. Remuez doucement et faites basculer la poign\u00e9e de la vanne pour faciliter l'entretien de l'\u00e9l\u00e9ment \u00e0 bille et le forcer \u00e0 bouger. Essayez \u00e9galement de retirer la poign\u00e9e de la valve et de tourner la valve plusieurs fois \u00e0 l'aide d'une pince pour l'aider \u00e0 bouger librement, puis replacez la poign\u00e9e sur la valve \u00e0 l'aide de sa vis. Si ces \u00e9tapes ne fonctionnent pas, passez \u00e0 l'\u00e9tape 2.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n","link":"https:\/\/zecovalve.com\/fr\/tag\/how-to-open-a-stuck-ball-valve","name":"Comment ouvrir un robinet \u00e0 boisseau sph\u00e9rique bloqu\u00e9","slug":"how-to-open-a-stuck-ball-valve","taxonomy":"post_tag","meta":[],"yoast_head":"\nHow to Open a Stuck Ball Valve?

ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"HOW TO OPEN A STUCK BALL VALVE What Causes Stuck Ball Valve? One of the most common types of ball valve failures involves a buildup of dirt and sediment within the valve, making it difficult to open and close. The use of solvent cement glue can also clog up the ball, causing it to stick to the inside of the valve and resist turning. If this happens, you\u2019ll want to take the valve apart and clean out any grime you see. Another frequent ball valve failure occurs when the elastic used to seal the valve (often in the form of an O-ring) gets worn down over time due to liquid or gas getting pushed through it. Since this is a natural symptom of use, you\u2019ll want to swap out the elastic when you notice cracks or leakage. Turning down the intensity of liquid flowing through the valve can also help extend the lifespan of the O-ring. As the elastic starts to go, so too does the inner packing of the valve stem. Any scratching or damage to the valve stem requires someone to either replace the stem or the whole valve before the whole thing falls apart. Make sure to look for leak points at the nuts holding the bolts in as well. This indicates that the nuts are too loose or that the end connector needs realignment. Damage to O-rings around the nuts can also prove a culprit of these leaks. How to Open A Stuck Ball Valve? Ball valves are commonly used valves for main water and various branch shutoffs. This valve functions as an ON\/OFF valve which means that the valve should be either completely open allowing full flow, or completely closed, stopping the entire water flow. Occasionally, it may be necessary to loosen a ball valve because it is stuck or tight, thereby creating an obstruction to fluid flow. If a ball valve won\u2019t open, perform the following steps to rectify the issue: Manual operation Turn off the main water supply. Then, loosen the valve by opening and closing it multiple times by turning its handle. Gently hammer the valve body multiple times on the valve body to break and free up the particles that are trapped between the ball and the valve body. Gently wiggle and rock the valve handle to help service the ball element and force it to move. Also, try to remove the valve handle and turn the valve a few times using a plier to help it move freely, and place the handle back on the valve using its screw. If these steps don\u2019t work, move on to step 2.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/fr\/tag\/how-to-open-a-stuck-ball-valve\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebSite\",\"@id\":\"https:\/\/zecovalve.com\/#website\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"ZECO Valve\",\"description\":\"Industrial Ball Valve, Gate Valve and Globe Valve Manufacturer\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":\"https:\/\/zecovalve.com\/?s={search_term_string}\",\"query-input\":\"required name=search_term_string\"}],\"inLanguage\":\"fr-FR\"},{\"@type\":\"CollectionPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/how-to-open-a-stuck-ball-valve#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/how-to-open-a-stuck-ball-valve\",\"name\":\"How to Open a Stuck Ball Valve?
