水流開關由磁(ci)芯、復(fu)位彈簧、鍛銅或聚(ju)碳(tan)外(wai)殼(ke)(ke)和傳感器組(zu)成。外(wai)殼(ke)(ke)為H58鍛銅或聚(ju)碳(tan)制造，磁(ci)芯采(cai)用(yong)釹(nv)鐵硼永磁(ci)材料，傳感器磁(ci)控開關則為進口中功率元件。
水(shui)(shui)(shui)流開關(guan)是(shi)用于電熱水(shui)(shui)(shui)器、太陽能熱水(shui)(shui)(shui)器、空調器以及其他水(shui)(shui)(shui)系統的水(shui)(shui)(shui)循環控(kong)(kong)制(zhi)(zhi)、進出(chu)水(shui)(shui)(shui)控(kong)(kong)制(zhi)(zhi)、水(shui)(shui)(shui)加(jia)熱控(kong)(kong)制(zhi)(zhi)、水(shui)(shui)(shui)泵開關(guan)控(kong)(kong)制(zhi)(zhi)、電磁(ci)閥通斷控(kong)(kong)制(zhi)(zhi)或(huo)出(chu)水(shui)(shui)(shui)斷電、出(chu)水(shui)(shui)(shui)通電控(kong)(kong)制(zhi)(zhi)等過程，當達到一定流量后將水(shui)(shui)(shui)流轉換為開關(guan)式電信號(hao)的傳感器件(jian)。
進水端與出水端接口(kou)均為(wei)G1/2″標準管(guan)螺紋,具有靈(ling)敏(min)度高、耐久性(xing)強等優點。
