品牌：RETZ瑞茨/我們一直致力于流體控制領(lǐng)域的持續(xù)創(chuàng)新，始于2005……進(jìn)口帶手動(dòng)控制電磁閥的性能特點(diǎn)與其他電磁閥性能一樣，手柄開關(guān)可以在電磁閥線圈無電或燒壞時(shí),實(shí)現(xiàn)手動(dòng)打開或關(guān)閉電磁閥，主要用于消防系統(tǒng)安全防護(hù)，在各種常溫、中溫、常壓、中壓等場合的純凈氣體、液體、瓦斯、油品、蒸汽、熱水的管路自動(dòng)控制The performance characteristics of RETZ with manual control solenoid valve are the same as those of other solenoid valves. The handle switch can manually open or close the solenoid valve when the solenoid valve coil is dead or burnt out. It is mainly used for fire protection system safety protection and automatic control of pure gas, liquid, gas, oil, steam, hot water pipelines in various normal temperature, medium temperature, atmospheric pressure, medium pressure and other occasions

進(jìn)口帶手動(dòng)控制電磁閥工作原理--Working principle of imported manual control solenoid valve

當(dāng)自動(dòng)控制時(shí)When under automatic control

常閉式-手動(dòng)開關(guān)指向關(guān)：線圈通電，電磁閥打開；線圈斷電，電磁閥關(guān)閉 Normally closed - manual switch pointing to close: the coil is energized and the solenoid valve is opened; Coil power off, solenoid valve closed

常開式-手動(dòng)開關(guān)向開的方向旋轉(zhuǎn)2~4圈，電磁閥不通電為打開狀態(tài)。當(dāng)線圈通電時(shí)，閥關(guān)閉 Normally open - Rotate the manual switch in the open direction for 2-4 turns, and the solenoid valve is in the open state when it is not energized. When the coil is energized, the valve closes

當(dāng)手動(dòng)控制時(shí) When manually controlled

旋轉(zhuǎn)手動(dòng)開關(guān)，常閉式手動(dòng)開關(guān)指向開的方向（常開式向開的方向旋轉(zhuǎn)2~4圈）電磁閥打開，介質(zhì)流通；旋轉(zhuǎn)手動(dòng)開關(guān)，常閉式手動(dòng)開關(guān)指向關(guān)的方向（常開式向關(guān)的方向旋轉(zhuǎn)到不動(dòng)為止）電磁閥關(guān)閉，介質(zhì)截止。

Rotate the manual switch, the normally closed manual switch points towards the open direction (the normally open switch rotates 2-4 turns towards the open direction), and the solenoid valve opens, allowing the medium to flow; Rotate the manual switch, with the normally closed manual switch pointing towards the closed direction (the normally open switch rotates towards the closed direction until it remains stationary). The solenoid valve is closed and the medium is cut off.
