DYC-JQ

■ DYC-JQ型－電磁真空帶充氣壓差閥

■ DYC-JQ型電磁真空帶充氣壓差閥是機(jī)械真空泵安全閥，安裝于機(jī)械真空泵的進(jìn)氣口，并與泵同步開啟和關(guān)閉。當(dāng)泵停止工作或電源突然中斷時(shí)，閥門利用大氣壓力使閥板自動(dòng)關(guān)閉，使真空系統(tǒng)保持真空并將大氣充入泵腔內(nèi)，從而避免泵油逆向流動(dòng)而污染真空系統(tǒng)。適用介質(zhì)為純凈空氣和非腐蝕性氣體。


■ DYC-JQ
Electro-vacuum Differential Pressure Valve

■ DYC-JQ electro-vacuum differential Pressure valve is a safely valve for mechanical vacuum pump. It is mounted at the intake nozzle of mechanical vacuum pump&def synchronously opened and closed with the pump. In case that pump stops working or power supply is suddenly broken off&def valve disc will be closed automatically under atmospheric pressure&def to keep the vacuum system vacuum and the air charged into pump cavity&def thus to prevent pump oil from reverse flow that can pollute the vacuum system. Applicable medium can be pure air or noncorrosive gases.
