1) 氣動(dòng)調(diào)節(jié)閥的型號(hào)包含閥體、執(zhí)行器、電氣智能定位器和其它氣動(dòng)附件。
● DN = 標(biāo)稱口徑
● kvs = 壓差為 100 千帕（1 巴）時(shí)，通過全開閥門 (H100) 的額定冷水 (5...30℃) 流量值
● Sv = 可調(diào)比
● Δps = 氣動(dòng)調(diào)節(jié)閥在壓力作用下牢固關(guān)閉時(shí)的閥門兩端zui大允許壓差
● Δpmax = 通過氣動(dòng)調(diào)節(jié)閥直通口整個(gè)行程范圍的閥門兩端zui大允許壓差 西門子氣動(dòng)執(zhí)行器描述常閉氣開型執(zhí)行器：氣缸進(jìn)氣時(shí)，閥軸向下運(yùn)動(dòng)，閥門開度變大。斷氣時(shí)，執(zhí)行器彈簧關(guān)閉閥門 保位功能描述： 無保位功能——斷氣時(shí)閥門關(guān)閉。
保位功能——當(dāng)供氣壓力小于氣動(dòng)保位閥設(shè)定壓力時(shí)，閥門保持當(dāng)前開度。 |
