DYC-JQ電磁真空壓差閥

DYC-JQ型電磁真(zhen)空(kong)(kong)壓差閥是機械真(zhen)空(kong)(kong)泵(beng)安(an)全閥,安(an)裝于機械真(zhen)空(kong)(kong)泵(beng)的(de)進氣口,并(bing)(bing)與泵(beng)同步開啟(qi)和關閉。當泵(beng)停止(zhi)工作或電源突然(ran)中斷時,閥門利用(yong)大(da)氣壓力使閥板自動關閉,使真(zhen)空(kong)(kong)系統保持真(zhen)空(kong)(kong)并(bing)(bing)將(jiang)大(da)氣充入(ru)泵(beng)腔內,從而避(bi)免泵(beng)油逆向流(liu)動而污染真(zhen)空(kong)(kong)系統。適用(yong)介(jie)質為純凈空(kong)(kong)氣和非腐(fu)蝕(shi)性氣體。

DYC-JQ型電磁真空壓差閥概述

DYC-JQElectro-vacuum Differential Pressure Valve

DYC-JQ型電磁(ci)真(zhen)空(kong)(kong)(kong)(kong)壓(ya)差閥(fa)是機械(xie)真(zhen)空(kong)(kong)(kong)(kong)泵安全閥(fa),安裝于機械(xie)真(zhen)空(kong)(kong)(kong)(kong)泵的進氣(qi)(qi)口,并與(yu)泵同步開啟(qi)和關(guan)閉。當泵停止工作或電源突然中斷(duan)時,閥(fa)門利用大氣(qi)(qi)壓(ya)力使(shi)閥(fa)板自動關(guan)閉,使(shi)真(zhen)空(kong)(kong)(kong)(kong)系統(tong)保持(chi)真(zhen)空(kong)(kong)(kong)(kong)并將大氣(qi)(qi)充入泵腔內,從而避(bi)免(mian)泵油逆向(xiang)流動而污(wu)染真(zhen)空(kong)(kong)(kong)(kong)系統(tong)。適用介(jie)質(zhi)為純凈(jing)空(kong)(kong)(kong)(kong)氣(qi)(qi)和非腐蝕性氣(qi)(qi)體。

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.
