一、500X泄壓閥介紹
500X泄壓持壓閥王要用于消防或其他供水系統(tǒng)中，以防止系統(tǒng)超壓或堅(jiān)持消防供水系統(tǒng)的壓力。消防泵關(guān)閉后還可以減小水錘的沖擊。也用于大型供水系統(tǒng)的水錘xc設(shè)備．并且閥門操控系統(tǒng)的進(jìn)口處裝有一個(gè)自清潔濾網(wǎng)，運(yùn)用流體特性，使比重較大、直徑較大的懸浮顆粒不會(huì)進(jìn)入操控系統(tǒng)．保證系統(tǒng)循環(huán)暢通無阻，使閥門能安全可靠地工作。系統(tǒng)動(dòng)作平穩(wěn)、強(qiáng)度高、運(yùn)用壽命長(zhǎng)適用于600口徑以下的管道。
