**供應(yīng)atos節(jié)流閥,阿托斯節(jié)流閥材質(zhì)
節(jié)流閥是通過改變節(jié)流截面或節(jié)流長度以控制流體流量的閥門。
將節(jié)流閥和單向閥并聯(lián)則可組合成單向節(jié)流閥。
Generally only for the load changes little or less stability requirements of the occasion.
Performance requirements
The performance requirements for the throttle valve are:
· Flow adjustment range is large, the flow of a pressure change smooth;
· Leakage within the small, if the leakage of oil leakage, the external leakage should be small;
· Adjust the torque is
對(duì)節(jié)流閥的**要**：
·流量調(diào)節(jié)范圍大，流量一壓差變化平滑；
·內(nèi)泄漏量小，若有外泄漏油口，外泄漏量也要??；
return flow control system and bypass throttling speed control system.
Throttle valve no flow negative feedback function,
can not compensate for the load caused by the instability caused by the speed
·調(diào)節(jié)力矩小，動(dòng)作靈敏。
節(jié)流閥的外形結(jié)構(gòu)與截止閥并無區(qū)別，只是它們啟閉件的形狀有所不同。
節(jié)流閥的啟閉件大多為圓錐流線型，通過它改變通道截面積而達(dá)到調(diào)節(jié)流量和壓力。
節(jié)流閥和單向節(jié)流閥是簡易的流量控制閥，在定量泵液壓系統(tǒng)中，節(jié)流閥和溢流閥配合，
可組成三種節(jié)流調(diào)速系統(tǒng)，即進(jìn)油路節(jié)流調(diào)速系統(tǒng)、回油路節(jié)流調(diào)速系統(tǒng)和旁路節(jié)流調(diào)速系統(tǒng)。
節(jié)流閥沒有流量負(fù)反饋功能，不能補(bǔ)償由負(fù)載變化所造成的速度不穩(wěn)定，
一般僅用于負(fù)載變化不大或?qū)λ俣确€(wěn)定性要求不*的場合。
**要求
The throttle valve is a valve that controls
the flow of fluid by changing the throttling section or throttling length.
The throttle valve and check valve can be combined into a one-way throttle valve.
Throttle and one-way throttle valve is a simple flow control valve,
in the quantitative pump hydraulic system, throttle and relief valve with,
Can be composed of three kinds of throttling speed control system,
that is, into the oil flow throttling speed control system,
