1、調(diào)節(jié)精度：自力式調(diào)節(jié)閥是由機(jī)械的方法組成的純比例調(diào)節(jié)系統(tǒng)，控制的結(jié)果必然存在靜差。調(diào)節(jié)精度一般為±5%~±10%。 </p> <p> 2、允許壓差：由于自力式調(diào)節(jié)閥沒(méi)有驅(qū)動(dòng)能源，*靠介質(zhì)自身的能源(壓力閥靠介質(zhì)壓力，液位閥靠介質(zhì)對(duì)浮球的浮力等)，而且無(wú)法象普通控制閥可通過(guò)提高氣源壓力來(lái)增大壓差。從而導(dǎo)致允許差壓較普通控制閥小，口徑也受限制。 </p><p> 直縫彎頭是應(yīng)用于批量生產(chǎn)無(wú)縫彎頭的成形工藝。目前，在常用規(guī)格的彎頭生產(chǎn)中已被熱推制法或其它成形工藝所替代，但在某些規(guī)格的彎頭中因生產(chǎn)數(shù)量少、壁厚過(guò)厚或過(guò)薄，沖壓成形彎頭的方法仍在使用。彎頭的沖壓成形采用與彎頭外徑相等的管坯，使用壓力機(jī)在模具中直接壓制成形。在沖壓前，管坯擺放在下模上，將內(nèi)芯及端模裝入管坯，上模向下運(yùn)動(dòng)開(kāi)始?jí)褐?，通過(guò)外模的約束和內(nèi)模的支撐作用使彎頭成形。與熱推制工藝相比，沖壓成形的外觀質(zhì)量不如前者；沖壓彎頭在成形時(shí)外弧處于拉伸狀態(tài)，沒(méi)有其它部位多余的金屬進(jìn)行補(bǔ)償，所以外弧處的壁厚約減薄10%左右。由于適用于單件生產(chǎn)和低成本的特點(diǎn)，故沖壓彎頭工藝多用于小批量、厚壁彎頭的制造。跟著無(wú)縫彎頭行業(yè)的成長(zhǎng)火速，浩繁的彎頭的企業(yè)不竭的實(shí)現(xiàn)了跨越式的成長(zhǎng)，先后履歷了作坊式的起步，規(guī)?；臄U(kuò)張以及財(cái)富化的成長(zhǎng)以及本世紀(jì)的進(jìn)提速等四個(gè)階段。無(wú)縫彎頭有什么優(yōu)點(diǎn)彎頭的沖壓成形采用與彎頭外徑相等的管坯，使用壓力機(jī)在模具中直接壓制成形。180度國(guó)標(biāo)無(wú)縫彎頭主要應(yīng)用于鍋爐管道、熱電廠等管道系統(tǒng)中.</p><div
