style="text-indent:25px">根據(jù)安全閥的結(jié)構可分為：重錘（杠桿）式安全閥：用杠桿和重錘來平衡閥瓣的壓力。重錘式安全閥靠移動重錘的位置或改變重錘的重量來調(diào)整壓力。它的優(yōu)點在于結(jié)構簡單；缺點是比較笨重回座力低。這種結(jié)構的安全閥只能用于固定的設備上。彈簧式安全閥：利用壓縮彈簧的力來平衡閥瓣的壓力并使之密封。彈簧式安全閥靠調(diào)節(jié)彈簧的壓縮量來調(diào)整壓力。它的優(yōu)點在于比重錘式安全閥體積小、輕便，靈敏度高，安裝位置不受嚴格限制；缺點是作用在閥桿上的力隨彈簧變形而發(fā)生變化。同時必須注意彈簧的隔熱和散熱問題。彈簧式安全閥的彈簧作用力一般不要超過2000公斤。因為過大過硬的彈簧不適于精確的工作。脈沖式安全閥：脈沖式安全閥由主閥和輔閥組成。主閥和輔閥連在一起，通過輔閥的脈沖作用帶動主閥動作。寧夏防爆緊急切斷閥品牌</p><p
