ZRHF電動(dòng)三通調(diào)節(jié)閥
概述
ZRHF(H)型電子式電動(dòng)三通調(diào)節(jié)閥有電動(dòng)三通合流調(diào)節(jié)閥與電動(dòng)三通分流調(diào)節(jié)閥兩種作用方式，在某些場合可以代替兩個(gè)二通閥和一個(gè)三通閥接管而得到廣泛運(yùn)用。實(shí)現(xiàn)對壓力、流量、溫度、液位等參數(shù)的調(diào)節(jié)，閥芯結(jié)構(gòu)采用圓筒薄壁窗口，并采用閥芯側(cè)面導(dǎo)向，穩(wěn)定性好、不易產(chǎn)生震動(dòng)、噪聲低、允許使用壓差大，連線簡單等特點(diǎn)。公稱通徑和壓差較小時(shí)，合流閥可用于分流場合，可互換使用，但公稱通徑大于DN100和壓差較大的分流場合，不能互換使用。
本公司的電動(dòng)三通調(diào)節(jié)閥，是由PSL系列和3810系列直行程電動(dòng)執(zhí)行機(jī)構(gòu)和三通調(diào)節(jié)閥體組成。(也可配其它品牌直行程執(zhí)行機(jī)構(gòu))。電動(dòng)執(zhí)行機(jī)構(gòu)為電子式一體化結(jié)構(gòu)，內(nèi)有伺服放大器，輸入控制信號(4-20mADC或1-5VDC)及電源即可控制閥門開度，達(dá)到對壓力、流量、液位、溫度等工參數(shù)的調(diào)節(jié)。電動(dòng)三通調(diào)節(jié)閥具有動(dòng)作靈敏、連線簡單、流量大、體積小、調(diào)節(jié)精度高等特點(diǎn)?？刂凭群托阅鼙菵KZ型有明顯提高。電動(dòng)三通調(diào)節(jié)閥具有調(diào)節(jié)精度高，動(dòng)作穩(wěn)定可靠等優(yōu)點(diǎn)。電動(dòng)三通合流調(diào)節(jié)閥主要用于將兩種流體混合成第三種流體；電動(dòng)三通分流調(diào)節(jié)閥主要用于將一股流體分成兩股流體。電動(dòng)三通調(diào)節(jié)閥產(chǎn)品可代替兩臺互為開關(guān)的單、雙座調(diào)節(jié)閥，用于液體、氣體、蒸汽等介質(zhì)的調(diào)節(jié)與控制。
