Como funcionam as v\u00e1lvulas de esfera?<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

As v\u00e1lvulas de esfera usam esferas ocas que permitem o fluxo atrav\u00e9s delas quando est\u00e3o abertas e isolam quando fecham. As esferas s\u00e3o acionadas por meio de fusos que se encaixam nas ranhuras fresadas nas esferas ocas, que por sua vez s\u00e3o acionadas por alavancas para fechar e abrir as esferas. Os eixos das v\u00e1lvulas esf\u00e9ricas s\u00e3o encaixados nos gargalos das v\u00e1lvulas e s\u00e3o vedados com uma ampla variedade de veda\u00e7\u00f5es de gargalo; isso evita vazamentos e, al\u00e9m disso, as esferas ficam imprensadas entre as sedes da esfera\/corpo para garantir uma veda\u00e7\u00e3o positiva e absoluta.<\/p>\n<\/div>\n\n\n\n

Fun\u00e7\u00e3o do circuito de v\u00e1lvulas de esfera<\/strong><\/h2>\n\n\n\n

As v\u00e1lvulas esfera podem apresentar 2 (2 vias), 3 (3 vias) e, em alguns casos, 4 portas (4 vias). A maioria das v\u00e1lvulas \u00e9 bidirecional e operada manualmente por meio de uma alavanca; esta alavanca fica alinhada com o tubo da v\u00e1lvula esf\u00e9rica sempre que a v\u00e1lvula \u00e9 aberta. Depois de fechada, a alavanca fica em posi\u00e7\u00e3o perpendicular ao tubo.<\/p>\n\n\n\n

O fluxo nas v\u00e1lvulas de esfera prov\u00e9m simplesmente da sa\u00edda e da entrada das v\u00e1lvulas de 2 vias. As v\u00e1lvulas operadas manualmente podem ser fechadas rapidamente, o que significa que h\u00e1 probabilidade de golpe de ar\u00edete com fluido de fluxo r\u00e1pido. Outras v\u00e1lvulas apresentam transmiss\u00f5es. As v\u00e1lvulas esfera de 3 vias possuem furos em forma de T ou L, que afetam as dire\u00e7\u00f5es dos fluxos; isso resulta em diferentes fun\u00e7\u00f5es do circuito, como misturar e distribuir fluxos em diferentes dire\u00e7\u00f5es.<\/p>\n\n\n\n

Alternativamente, voc\u00ea pode usar v\u00e1lvulas de esfera automatizadas; estes s\u00e3o equipados com atuadores pneum\u00e1ticos ou el\u00e9tricos. Eles oferecem mais comodidade, pois podem ser operados remotamente.<\/p>\n<\/div>\n\n\n\n

Opera\u00e7\u00e3o de v\u00e1lvulas de esfera<\/strong><\/h2>\n\n\n\n

\u00c0 medida que as esferas abrem e fecham entre os assentos, elas realizam movimentos de limpeza e removem quaisquer part\u00edculas suspensas das superf\u00edcies das esferas. \u00c9 importante observar que os s\u00f3lidos grossos danificam as superf\u00edcies e sedes das esferas, o que eventualmente resulta em vazamentos. Materiais fibrosos, mesquinhos e s\u00f3lidos ajudam a evitar o fechamento das bolas. O layout de v\u00e1lvula esfera mais comum \u00e9 o projeto de 2 vias; facilita a passagem dos fluxos das entradas para as sa\u00eddas das v\u00e1lvulas. As v\u00e1lvulas esfera de 3 e 4 vias ajudam os fluxos a se moverem em diversas dire\u00e7\u00f5es.<\/p>\n<\/div>\n\n\n\n

How Does Ball Valves Work? Ball valves use hollow balls that allow flows through them when they are open and isolate when they close. The balls are driven using spindles that fit into the slots milled into the hollow balls, which are in turn operated by levers to close and open the balls.
