大慣量（寬調(diào)速）直流伺服電動(dòng)機(jī)雖然具有上述特點(diǎn)，但是，對(duì)它進(jìn)行控制不如步進(jìn)電機(jī)簡(jiǎn)單，快速響應(yīng)性能也不如小摜量電動(dòng)機(jī)，寬調(diào)速直流伺服電動(dòng)機(jī)轉(zhuǎn)子由于采用良好的絕緣，耐溫可達(dá)150～200℃。轉(zhuǎn)子溫度高，熱量通過(guò)轉(zhuǎn)軸傳到絲桿，絲杠的變形將影響傳動(dòng)精度，因此，出現(xiàn)了熱管形的大慣量電機(jī)，即將電機(jī)軸做成空心，在軸內(nèi)裝氟里昂之類的工作介質(zhì)，介質(zhì)在管內(nèi)反復(fù)蒸發(fā)和冷卻，將熱量由高溫區(qū)傳至低溫區(qū)，終散發(fā)到周?chē)h(huán)境中去。

　伺服電機(jī)被步進(jìn)脈沖控制的優(yōu)點(diǎn):
　　(1)可靠性高，不易發(fā)生飛車(chē)事故。用模擬電壓方式控制伺服電機(jī)時(shí)，如果出現(xiàn)接線接錯(cuò)或使用中元件損壞等問(wèn)題時(shí)，有可能使控制電壓升至正的值。這種情況是很危險(xiǎn)的。如果用脈沖作為控制信號(hào)就不會(huì)出現(xiàn)這種問(wèn)題。
　　(2)信號(hào)抗干擾性能好。數(shù)字電路抗干擾性能是模擬電路難以比擬的。

為此，現(xiàn)在上又開(kāi)發(fā)金屬密封蝶閥，氣蝕區(qū)減小，近幾年我國(guó)也開(kāi)發(fā)了金屬密封蝶閥，在日本近年來(lái)還開(kāi)發(fā)耐氣蝕、低振動(dòng)、低噪聲的梳齒形蝶閥。一般密封座的壽命在正常情況下，橡膠15年-2年，金屬的8年-9年。但如何正確選用則要根據(jù)工況要求。蝶閥的使用：蝶閥的開(kāi)度與流量之間的關(guān)系，基本上呈線性比例變化。如果用于控制流量，其流量特性與配管的流阻也有密切關(guān)系，如兩條管道安裝閥門(mén)口徑、形式等全相同，而管道損失系數(shù)不同，閥門(mén)的流量差別也會(huì)很大。
