DR20-7-L5X/10Y上海立新先導(dǎo)式減壓閥

介質(zhì)特性

1）質(zhì)氣，液態(tài)或混合狀態(tài)分別選用不同品種的電磁閥；

2）介質(zhì)溫度不同規(guī)格產(chǎn)品，否則線圈會(huì)燒掉，密封件老化，嚴(yán)重影響使用壽命；

3）介質(zhì)粘度，通常在50cSt以下。若超過(guò)此值，通徑大于15mm時(shí)，用多功能電磁閥；通徑小于15mm時(shí)，用高粘度電磁閥。

4）介質(zhì)清潔度不高時(shí)都應(yīng)在電磁閥前配裝反沖過(guò)濾閥，壓力低時(shí)，可選用直動(dòng)膜片式電磁閥；

5）介質(zhì)若是定向流通，且不允許倒流，需用雙向流通；

6）介質(zhì)溫度應(yīng)選在電磁閥允許范圍之內(nèi)。

2、管道參數(shù)

1）根據(jù)介質(zhì)流向要求及管道連接方式選擇閥門(mén)通口及型號(hào)；

2）根據(jù)流量和閥門(mén)Kv值選定公稱(chēng)通徑，也可選同管道內(nèi)徑；

3）工作壓差：低工作壓差在0.04Mpa以上是可選用間接先導(dǎo)式；低工作壓差接近或小于零的必須選用直動(dòng)式或分步直接式。

3、環(huán)境條件
