As v\u00e1lvulas gaveta s\u00e3o mais comuns como v\u00e1lvulas de n\u00edvel inferior. Uma v\u00e1lvula gaveta de a\u00e7o forjado \u00e9 uma v\u00e1lvula amplamente utilizada que se refere a uma v\u00e1lvula na qual o membro de fechamento (gate) se move na dire\u00e7\u00e3o vertical ao longo da linha central da passagem. A v\u00e1lvula gaveta \u00e9 usada principalmente para corte na tubula\u00e7\u00e3o. Geralmente, \u00e9 utilizado o dispositivo de corte com di\u00e2metro DN \u2265 500 mm, e \u00e0s vezes o dispositivo de corte com di\u00e2metro pequeno tamb\u00e9m utiliza uma v\u00e1lvula gaveta.<\/p>\n

Vantagens da v\u00e1lvula gaveta de a\u00e7o forjado:<\/p>\n

1. A resist\u00eancia ao fluido \u00e9 pequena.<\/p>\n

2. A for\u00e7a externa necess\u00e1ria para abrir e fechar \u00e9 pequena.<\/p>\n

3. A dire\u00e7\u00e3o do fluxo do meio n\u00e3o \u00e9 limitada.<\/p>\n

4. Quando totalmente aberta, a superf\u00edcie de veda\u00e7\u00e3o \u00e9 menos afetada pelo meio de trabalho do que a v\u00e1lvula de corte.<\/p>\n

5, o formato do corpo \u00e9 relativamente simples, o processo de fundi\u00e7\u00e3o \u00e9 melhor.<\/p>\n

Desvantagens da v\u00e1lvula gaveta de a\u00e7o forjado:<\/p>\n

1. As dimens\u00f5es externas e a altura de abertura s\u00e3o grandes. O espa\u00e7o necess\u00e1rio para instala\u00e7\u00e3o \u00e9 grande.<\/p>\n

2. Durante o processo de abertura e fechamento, h\u00e1 atrito relativo entre as superf\u00edcies de veda\u00e7\u00e3o, o que pode causar arranh\u00f5es.<\/p>\n

3. As v\u00e1lvulas gaveta geralmente possuem duas faces de veda\u00e7\u00e3o, o que acrescenta algumas dificuldades ao processamento, retifica\u00e7\u00e3o e manuten\u00e7\u00e3o.<\/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.
