DYC-JQ電磁真空帶充氣壓差閥

■產(chǎn)品概述

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, synchronously opened and closed with the pump. In case that pump stops working or power

supply is suddenly broken off, valve disc will be closed automatically under atmospheric pressure, to keep the vacuum system

vacuum and the air charged into pump cavity, thus to prevent pump oil from reverse flow that can pollute the vacuum system.

Applicable medium can be pure air or noncorrosive gases.
