I. Overview

DYC-JQ型电磁真空压差阀 是机械真空泵安全阀,安装于机械真空泵的进气口,并与泵同步开启和关闭。 DDC-JQ type electromagnetic vacuum belt inflation valve and DYC-JQ type electromagnetic vacuum pressure difference valve are mechanical vacuum pump safety valves. They are installed at the inlet of mechanical vacuum pumps and are opened and closed simultaneously with the pump. The valve closes automatically when the pump stops working or the power is suddenly interrupted. Keep the vacuum system vacuum and fill the atmosphere into the pump cavity to avoid contaminating the vacuum system due to the reverse flow of pump oil. The applicable medium is pure air and non-corrosive gas.
