O que causa o travamento V\u00e1lvula de esfera<\/a><\/mark><\/strong>?<\/h2>\r\n\r\n\r\n\r\n\r\nUm dos tipos mais comuns de falhas em v\u00e1lvulas esf\u00e9ricas envolve o ac\u00famulo de sujeira e sedimentos dentro da v\u00e1lvula, dificultando sua abertura e fechamento. O uso de cola de cimento solvente tamb\u00e9m pode entupir a esfera, fazendo com que ela grude no interior da v\u00e1lvula e resista ao giro. Se isso acontecer, voc\u00ea vai querer desmontar a v\u00e1lvula e limpar qualquer sujeira que encontrar.\r\n\r\n\r\n\r\n\r\n\r\nOutra falha frequente da v\u00e1lvula esf\u00e9rica ocorre quando o el\u00e1stico usado para vedar a v\u00e1lvula (geralmente na forma de um anel de veda\u00e7\u00e3o) se desgasta com o tempo devido ao l\u00edquido ou g\u00e1s sendo empurrado atrav\u00e9s dele. Como este \u00e9 um sintoma natural de uso, voc\u00ea deve trocar o el\u00e1stico quando notar rachaduras ou vazamentos. Diminuir a intensidade do l\u00edquido que flui atrav\u00e9s da v\u00e1lvula tamb\u00e9m pode ajudar a prolongar a vida \u00fatil do O-ring.\r\n\r\n\r\n\r\n\r\n\r\n\u00c0 medida que o el\u00e1stico come\u00e7a a se soltar, o mesmo acontece com a gaxeta interna da haste da v\u00e1lvula. Qualquer arranh\u00e3o ou dano \u00e0 haste da v\u00e1lvula exige que algu\u00e9m substitua a haste ou a v\u00e1lvula inteira antes que tudo desmorone.\r\n\r\n\r\n\r\n\r\n\r\nCertifique-se de procurar pontos de vazamento nas porcas que prendem os parafusos tamb\u00e9m. Isso indica que as porcas est\u00e3o muito soltas ou que o conector final precisa de realinhamento. Danos aos an\u00e9is de veda\u00e7\u00e3o ao redor das porcas tamb\u00e9m podem ser os culpados desses vazamentos.\r\n\r\n\r\n\r\n\r\n

Como abrir uma v\u00e1lvula de esfera presa?<\/h2>\r\n\r\n\r\n\r\n\r\nAs v\u00e1lvulas de esfera s\u00e3o v\u00e1lvulas comumente usadas para \u00e1gua principal e v\u00e1rios cortes de ramais. Esta v\u00e1lvula funciona como uma v\u00e1lvula ON\/OFF, o que significa que a v\u00e1lvula deve estar completamente aberta, permitindo o fluxo total, ou completamente fechada, interrompendo todo o fluxo de \u00e1gua. Ocasionalmente, pode ser necess\u00e1rio afrouxar uma v\u00e1lvula esf\u00e9rica porque ela est\u00e1 presa ou apertada, criando assim uma obstru\u00e7\u00e3o ao fluxo do fluido. Se uma v\u00e1lvula esf\u00e9rica n\u00e3o abrir, execute as seguintes etapas para corrigir o problema:\r\n\r\n\r\n\r\n\r\n
    \r\n \t
  1. Opera\u00e7\u00e3o manual<\/li>\r\n \t
  2. Desligue o abastecimento principal de \u00e1gua.<\/li>\r\n \t
  3. Em seguida, afrouxe a v\u00e1lvula abrindo e fechando-a v\u00e1rias vezes girando sua manivela.<\/li>\r\n \t
  4. Martele suavemente o corpo da v\u00e1lvula v\u00e1rias vezes no corpo da v\u00e1lvula para quebrar e liberar as part\u00edculas que est\u00e3o presas entre a esfera e o corpo da v\u00e1lvula.<\/li>\r\n \t
  5. Agite e balance suavemente a alavanca da v\u00e1lvula para ajudar na manuten\u00e7\u00e3o do elemento esf\u00e9rico e for\u00e7\u00e1-lo a se mover. Al\u00e9m disso, tente remover a al\u00e7a da v\u00e1lvula e gire a v\u00e1lvula algumas vezes usando um alicate para ajud\u00e1-la a se mover livremente, e coloque a al\u00e7a de volta na v\u00e1lvula usando seu parafuso. Se essas etapas n\u00e3o funcionarem, v\u00e1 para a etapa 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\/pt\/tag\/how-to-open-a-stuck-ball-valve","name":"Como abrir uma v\u00e1lvula de esfera bloqueada","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\/pt\/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\":\"pt-PT\"},{\"@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?
