安全閥結(jié)構(gòu)主要有兩大類：彈簧式和杠桿式。彈簧式是指閥瓣與閥座的密封靠彈簧的作用力。杠桿式是靠杠桿和重錘的作用力。隨著大容量的需要，又有一種脈沖式安全閥，上海不銹鋼閘閥銷售廠，也稱為先導(dǎo)式安全閥，由主安全閥和輔助閥組成。當管道內(nèi)介質(zhì)壓力超過規(guī)定壓力值時，輔助閥先開啟，介質(zhì)沿著導(dǎo)管進入主安全閥，并將主安全閥打開，上海不銹鋼閘閥銷售廠，使增高的介質(zhì)壓力降低。</span><span style="font-size:12px;">安全閥的排放量決定于閥座的口徑與閥瓣的開啟高度，也可分為兩種：微啟式開啟高度是閥座內(nèi)徑的（1/20）～（1/40），全啟式是（1/3）～（1/4），上海不銹鋼閘閥銷售廠。</span> </p> <p> <br /> 不銹鋼閘閥找耐腐。。上海不銹鋼閘閥銷售廠</p><div style="width:100%;text-align:
