進口氣動小流量調(diào)節(jié)閥
進口氣動小流量調(diào)節(jié)閥,進口電動小流量調(diào)節(jié)閥,進口小流量調(diào)節(jié)閥,美國約克進口調(diào)節(jié)閥
進口氣動小流量調(diào)節(jié)閥概述:
進口氣動小流量調(diào)節(jié)閥又稱鍋爐給水泵再循環(huán)閥。在電廠它安裝在給水泵出口處,連接至除氧器。鍋爐給水泵把水從除氧器里吸出送往鍋爐。為防止給水泵過熱以及防止產(chǎn)生汽蝕,給水泵的流量在任何情況下都必須不小于某一個規(guī)定的安全流量,也就是zui小流量。當(dāng)鍋爐給水需要流量很小時,比如汽機跳閘時,需及時打開zui小流量閥,把一部分高壓水由泵出口處回流到除氧器,以保證給水泵的安全運行。該閥所在的系統(tǒng)稱為再循環(huán)系統(tǒng)。
氣動薄膜小流量調(diào)節(jié)閥,由氣動薄膜多彈簧執(zhí)行機構(gòu)和小流量閥組成。
電動小流量調(diào)節(jié)閥,由電子式電動執(zhí)行機構(gòu)和小流量閥組成。
適用于較小流量的調(diào)節(jié),它具有結(jié)構(gòu)緊湊,體積小,重量輕,安裝維護方便的特點。
