美國(guó)派克PARKER氣動(dòng)閥,PARKER氣控閥
1,氣動(dòng)調(diào)節(jié)閥的工作原理：氣動(dòng)調(diào)節(jié)閥由執(zhí)行機(jī)構(gòu)和調(diào)節(jié)機(jī)構(gòu)組成。執(zhí)行機(jī)構(gòu)是調(diào)節(jié)閥的推力部件,它按控制信號(hào)壓力的大小產(chǎn)生相應(yīng)的推力,推動(dòng)調(diào)節(jié)機(jī)構(gòu)動(dòng)作。閥體是氣動(dòng)調(diào)節(jié)閥的調(diào)節(jié)部件,它直接與調(diào)節(jié)介質(zhì)接觸,調(diào)節(jié)該流體的流量。
2.公稱壓力：(Nominal pressure),表示符號(hào)PN,在一定溫度下應(yīng)用時(shí)允許的最大工作壓力。對(duì)碳鋼閥體的控制閥,指200℃以下應(yīng)用時(shí)允許的最大工作壓力；對(duì)鑄鐵閥體,指120℃以下應(yīng)用時(shí)允許的最大工作壓力；對(duì)不銹鋼閥體的控制閥,指250℃以下應(yīng)用時(shí)允許的最大工作壓力。當(dāng)工作溫度升高時(shí),閥體的耐壓會(huì)降低。
例如,公稱壓力為6.4MPa(PN64)的碳鋼控制閥,用于300℃時(shí)的耐壓為5.2MPa,用400℃時(shí)的耐壓為4.1MPa,用于450℃時(shí)的耐壓為2.9MPa。因此,控制閥公稱壓力的確定不僅要根據(jù)最高工作壓力,還需根據(jù)最高工作溫度和材質(zhì)特性,而不僅僅只需滿足公稱壓力大于工作壓力
