2.1根据介质流向要求及管道连接方式选择阀门通口及型号。例如,用于一条管道向两条管道切换的,小通径的选CA5和Z3F,中等或大通径请选ZDF—Z1/2。又如控制两条管道汇流的,请选ZDF—Z2/1等。
2.2根据流量和阀门Kv值选定公称通径,也可选同管道内径。请注意有的厂家未标有Kv值,往往阀孔尺寸小于接口管径,切不可贪图价低而误事。
2.3工作压差zui低工作压差在0、04Mpa以上是可选用间接先导式;zui低工作压差接近或小于零的必须选用直动式或分步直接式。
3、环境条件
3.1环境的zui高和zui低温度应选在允许范围之内,如有超差需作特殊订货提出。
3.2环境中相对湿度高及有水滴雨淋等场合,应选防水电磁阀
3.3环境中经常有振动,颠簸和冲击等场合应选特殊品种,例如船用电磁阀。
3.4在有腐蚀性或爆炸性环境中的使用应优先根据安全性要求选用耐发蚀
3.5环境空间若受限制,请选用多功能电磁阀,因其省去了旁路及三只手动阀且便于在线维修。力士乐溢流阀R900245523,DBW30B2-5X/350X6EG24N9K4
