CCQ型－氣動(dòng)超高真空插板閥 ■ CCQ型氣動(dòng)超高真空插板閥是通過電磁換向閥改變氣路方向，控制執(zhí)行氣缸驅(qū)動(dòng)閥板作上下運(yùn)動(dòng)，達(dá)到閥門的開啟或關(guān)閉。閥門用于接通或切斷真空管路中的氣流。適用介質(zhì)為凈空氣和非腐蝕性氣體。 帶反饋信號(hào)裝置。 ■ CCQ Pneumatic Ultra-high Vacuum Gate Valve ■ CCQ pneumatic ultra-high vacuum gate valve uses solenoid directional valve to change the direction of air passage, and controls the actuating cylinder to drive the valve disc up and down to make the valve opened or closed. It is used to put through or cut off the air passage in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases. With signal feedback device. ■ 主要技術(shù)性能 Main Technical Performance ■ ■ ■ 　適用范圍：Applicability 　105～1.3×10-7Pa 　閥門漏率：Valve Leak Rate 　≤1.3×10-7Pa.L/S.(DN≤200) 　≤6.7×10-7Pa.L/S.(DN≥250) 　適用溫度：Applicable Temperature 　-30～ 150℃ 　閥門開啟時(shí)閥板兩側(cè)的壓差： 　 The differential pressure between the two sides of valve disc upon valve opening: 　≤2.7×103Pa. 　氣源壓力：Annoy pressure 　0.4～0.6MPa ■ 主要零件材料 Materials of Main Parts ■ ■ 閥體、閥板：不銹鋼 密封件：氟橡膠、波紋管(軸封)、丁腈橡膠。 Body, and disc: stainless steel Sealing element: Viton, bellows(shaft seal), NBR CONSTRUCTION FIGHTS(mm)
