撙节阀是颠末过程改不雅观撙节截面或者撙节长度以节制流体流量的阀门。将撙节阀和单向阀并联则可组分化单向撙节阀。撙节阀和单向撙节阀是简单纯真的流量节制阀,在定量泵液压系统中,撙节阀和溢流阀共同,可组成三种撙节调速系统,即进油路撙节调速系统,回油路撙节调速系统和旁路撙节调速系统。撙节阀没有流量负反映功能,不克不及补偿由负载改观所变成的速率不不变,一般仅用于负载改观不年夜年夜或者对速率不变性要求不高的场合。撙节阀按通道编制可分为直通式和角式两种;按启闭件的外形分,有针形,沟形和窗形三种。可调治撙节阀:阀针和阀芯采纳硬质合金制造,产品按api6a尺度假想,具备耐磨,耐冲洗机能。次要用于井口采油(气)树设备,滑套式撙节阀:阀芯采纳低噪音失调型布局,开启轻便,产品按api6a尺度假想,阀芯外不雅观笼罩碳化钨,适合于有闪蒸,低压差,低压力,空化等条件刻薄的场合,利用刻日长,流量调治精度年夜年夜年夜年夜普及。合用于石油,天然气,化工,炼油,水电等行业。
