Les vannes \u00e0 vanne sont plus courantes en tant que vannes de niveau inf\u00e9rieur. Un robinet-vanne en acier forg\u00e9 est une vanne largement utilis\u00e9e qui fait r\u00e9f\u00e9rence \u00e0 une vanne dans laquelle l'\u00e9l\u00e9ment de fermeture (porte) se d\u00e9place dans la direction verticale le long de la ligne m\u00e9diane du passage. Le robinet-vanne est principalement utilis\u00e9 pour couper le pipeline. G\u00e9n\u00e9ralement, le dispositif de coupe d'un diam\u00e8tre DN \u2265 500 mm est utilis\u00e9, et parfois le dispositif de coupe de petit diam\u00e8tre utilise \u00e9galement un robinet-vanne.<\/p>\n

Avantages du robinet-vanne en acier forg\u00e9\u00a0:<\/p>\n

1. La r\u00e9sistance du fluide est faible.<\/p>\n

2. La force externe requise pour l'ouverture et la fermeture est faible.<\/p>\n

3. Le sens d'\u00e9coulement du fluide n'est pas limit\u00e9.<\/p>\n

4. Lorsqu'elle est compl\u00e8tement ouverte, la surface d'\u00e9tanch\u00e9it\u00e9 est moins affect\u00e9e par le fluide de travail que la vanne d'arr\u00eat.<\/p>\n

5, la forme du corps est relativement simple, le processus de moulage est meilleur.<\/p>\n

Inconv\u00e9nients du robinet-vanne en acier forg\u00e9\u00a0:<\/p>\n

1. Les dimensions ext\u00e9rieures et la hauteur d'ouverture sont grandes. L'espace requis pour l'installation est grand.<\/p>\n

2. Pendant le processus d'ouverture et de fermeture, il y a un frottement relatif entre les surfaces d'\u00e9tanch\u00e9it\u00e9, ce qui est susceptible de provoquer des rayures.<\/p>\n

3. Les robinets-vannes ont g\u00e9n\u00e9ralement deux faces d'\u00e9tanch\u00e9it\u00e9, ce qui ajoute quelques difficult\u00e9s au traitement, au meulage et \u00e0 l'entretien.<\/p>","protected":false},"excerpt":{"rendered":"

Gate valves are more common as a lower level valve. A forged steel gate valve is a widely used valve that refers to a valve in which the closing member (gate) moves in the vertical direction along the centerline of the passage. The gate valve is mainly used for cutting in the pipeline. Generally, the […]<\/p>\n","protected":false},"author":290641,"featured_media":4398,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16],"tags":[519,553,554],"class_list":["post-4397","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-news","tag-api-602-forged-valves","tag-disadvantages-of-forged-steel-gate-valves","tag-dvantages-of-forged-steel-gate-valve"],"_links":{"self":[{"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/posts\/4397","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/users\/290641"}],"replies":[{"embeddable":true,"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/comments?post=4397"}],"version-history":[{"count":0,"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/posts\/4397\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/media\/4398"}],"wp:attachment":[{"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/media?parent=4397"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/categories?post=4397"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/tags?post=4397"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
