After the grease gun is refueled, the operator selects the valve and the grease injection method after the low temperature shut-off valve, and then performs the grease filling operation. There are two kinds of conditions for the forged steel gate valve: on the one hand, the amount of grease is less than that of the grease, and the sealing surface is accelerated by the lack of lubricant. On the other hand, excessive fat injection causes waste. There is no accurate calculation of the different valve sealing capacities based on the valve type category. The sealing capacity can be calculated in terms of valve size and type, and a proper amount of grease can be injected reasonably.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>2, as v\u00e1lvulas de gaveta de a\u00e7o forjado geralmente ignoram os problemas de press\u00e3o. Na opera\u00e7\u00e3o de inje\u00e7\u00e3o de graxa, o purgador de vapor do tipo flutuador semi-livre regular carregado com graxa tem uma mudan\u00e7a de pico para vale. A press\u00e3o est\u00e1 muito baixa, a veda\u00e7\u00e3o vaza ou a v\u00e1lvula de seguran\u00e7a falha, a press\u00e3o est\u00e1 muito alta, o fabricante da v\u00e1lvula da porta de graxa est\u00e1 entupido, a graxa da veda\u00e7\u00e3o endurece ou o anel de veda\u00e7\u00e3o e a esfera da v\u00e1lvula e a placa da v\u00e1lvula est\u00e3o travados. Normalmente, quando a press\u00e3o da graxa \u00e9 muito baixa, a graxa injetada flui para o fundo da cavidade da v\u00e1lvula, o que geralmente ocorre em uma v\u00e1lvula gaveta pequena. A press\u00e3o da v\u00e1lvula de controle de fluxo de graxa est\u00e1 muito alta. Por um lado, a v\u00e1lvula gaveta de graxa \u00e9 inspecionada e o bico de graxa \u00e9 inspecionado. Se o orif\u00edcio da v\u00e1lvula flutuante do controle remoto de graxa estiver bloqueado, a veda\u00e7\u00e3o da mola ser\u00e1 substitu\u00edda por uma chave inglesa. A outra v\u00e1lvula de \u00eambolo \u00e9 uma graxa. Para endurecer, use uma solu\u00e7\u00e3o de limpeza, amole\u00e7a repetidamente a graxa de veda\u00e7\u00e3o com falha e injete uma nova graxa para substitu\u00ed-la. Al\u00e9m disso, o tipo de veda\u00e7\u00e3o e o material de veda\u00e7\u00e3o tamb\u00e9m afetam a press\u00e3o de enchimento da graxa. Diferentes formas de veda\u00e7\u00e3o t\u00eam diferentes press\u00f5es de enchimento de graxa. Geralmente, a press\u00e3o da graxa para veda\u00e7\u00e3o dura \u00e9 maior que a da veda\u00e7\u00e3o macia.<\/p>\r\n\r\n\r\n\r\n<p>As v\u00e1lvulas globo de a\u00e7o forjado prestam aten\u00e7\u00e3o ao problema da v\u00e1lvula na posi\u00e7\u00e3o do interruptor. A v\u00e1lvula esf\u00e9rica normalmente est\u00e1 na posi\u00e7\u00e3o aberta durante a manuten\u00e7\u00e3o e manuten\u00e7\u00e3o. Em casos especiais, a manuten\u00e7\u00e3o \u00e9 desligada. Outras v\u00e1lvulas n\u00e3o podem ser discutidas em termos de abertura. As v\u00e1lvulas de corte de a\u00e7o forjado devem ser fechadas durante a manuten\u00e7\u00e3o para garantir que a graxa preencha a ranhura da veda\u00e7\u00e3o ao longo da veda\u00e7\u00e3o. Se estiver aberto, a graxa da veda\u00e7\u00e3o cair\u00e1 diretamente no corredor ou na cavidade da v\u00e1lvula, causando desperd\u00edcio. Quando a v\u00e1lvula \u00e9 lubrificada, o problema da inje\u00e7\u00e3o de graxa \u00e9 frequentemente ignorado. A press\u00e3o, a quantidade de inje\u00e7\u00e3o de graxa e a posi\u00e7\u00e3o do interruptor s\u00e3o normais durante a opera\u00e7\u00e3o de enchimento de graxa. No entanto, para garantir o efeito de enchimento de graxa da v\u00e1lvula, \u00e0s vezes \u00e9 necess\u00e1rio abrir ou fechar a v\u00e1lvula para verificar o efeito de lubrifica\u00e7\u00e3o e confirmar se a esfera da v\u00e1lvula ou a superf\u00edcie da v\u00e1lvula est\u00e1 lubrificada uniformemente.<\/p>","protected":false},"excerpt":{"rendered":"<p>What should we pay attention to when using self-sealing forged steel valves?
