工作原理:采用帶隔離膜片的兩位三通電磁閥
這樣閥門被污染的介質(zhì)堵塞的危
這種特殊電磁閥的尺寸為 DN 10 - 65 mm,
并在彈簧力的輔助下將膜片向下壓,關(guān)
即可將常閉功能的主閥改為常開功能。
膜片上方平衡室內(nèi)的介質(zhì)壓力被釋放。
所以這種閥需要閥門入口與出口之間有一個(gè)小壓差。
當(dāng)先導(dǎo)閥關(guān)閉時(shí),
You can normally closed the main function of the valve to normally open function.
Since there is no physical connection between the pilot valve and the diaphragm,
閉,通過上游先導(dǎo)通道使平衡室的介質(zhì)壓力再次升高,
主要適用于微污染介質(zhì)和腐蝕性介質(zhì)。
閉閥門。有些閥門還可調(diào)整打開和關(guān)閉的時(shí)間,
以適合于實(shí)際應(yīng)用。
Insurance is much smaller. Another advantage is:
As long as the pilot valve is rotated 180 degrees,
由于先導(dǎo)閥與膜片之間沒有物理連接,
密封為較大的膜片。
與兩位兩通先導(dǎo)閥相同:當(dāng)
先導(dǎo)閥打開時(shí),
So this valve requires a minimum pressure difference between the valve inlet and the outlet.
The size of this special solenoid valve is DN 10 - 65 mm,
Mainly applicable to micro-polluting media and corrosive media.
并且在打開位置沒有介質(zhì)流過先導(dǎo)閥,
膜片上無平衡孔,
下游平衡通道關(guān)
險(xiǎn)就要小得多。
