style="text-indent:25px">焊接高壓止回閥結(jié)構(gòu)特點：焊接止回閥一般分為升降式、旋啟式等幾種類型。升降式止回閥的結(jié)構(gòu)一般與截止閥相似，其閥瓣沿著通道中心線作升降運動，動作可靠，但流體阻力較大，適用于較小口徑的場合。升降式止回閥可分為直通式和立式兩種。直通式升降式止回閥一般只能安裝在水平管路，而立式升降止回閥一般應(yīng)安裝在垂直管路。旋啟式止回閥的閥瓣繞轉(zhuǎn)軸作旋轉(zhuǎn)運動。其流體阻力一般小于升降式止回閥，它適用于較大口徑的場合。旋啟式止回閥根據(jù)閥瓣的數(shù)目可分為單瓣旋啟式、雙瓣旋啟式及多瓣旋啟式三種。單瓣旋啟式止回閥一般適用于中等口徑的場合。大口徑管路選用單瓣旋啟式止回閥時，為減少水錘壓力，*采用能減小水錘壓力的緩閉止回閥。雙瓣旋啟式止回閥適用于大中口徑管路。對夾雙瓣旋啟式止回閥結(jié)構(gòu)小、重量輕，是一種發(fā)展較快的止回閥；多瓣旋啟式止回閥適用于大口徑管道路。</p></p><br
