二、進(jìn)口低真空電磁壓差充氣閥產(chǎn)品概述：

德國(guó)《DE LOCKE》洛克進(jìn)口低真空電磁壓差充氣閥，是安裝在機(jī)械真空泵進(jìn)氣口上一種新型真空閥。其工作原理是機(jī)械泵的電源和電磁閥線圈的電源接在同一電路上，當(dāng)機(jī)械真空泵因工作需要突然停電、停止運(yùn)轉(zhuǎn)時(shí)，該閥利用大氣壓力使閥芯自動(dòng)關(guān)閉，截止和真空系統(tǒng)相連的通道，同時(shí)向泵內(nèi)放大氣，防止機(jī)械泵油返回真空系統(tǒng)，起到了保護(hù)真空系統(tǒng)作用，有利于機(jī)械泵再啟動(dòng)。

適用的工作介質(zhì)為空氣及非腐蝕性氣體。

Introduction of imported low vacuum electromagnetic differential pressure charging valve products:
German "de Locke" imported low vacuum electromagnetic differential pressure charging valve is a new type of vacuum valve installed on the air inlet of mechanical vacuum pump. Its working principle is that the power supply of the mechanical pump and the power supply of the solenoid valve coil are connected to the same circuit. When the mechanical vacuum pump is suddenly cut off due to the need of work, the valve uses atmospheric pressure to make the valve core automatically close, cut off the channel connected with the vacuum system, and at the same time, release the atmosphere into the pump to prevent the mechanical pump oil from returning to the vacuum system, which plays a role in protecting the vacuum system and is beneficial to the environment Restart the mechanical pump.
The suitable working medium is air and non corrosive gas.
