**供應atos節流閥,阿托斯節流閥材質(zhì)
節流閥供在壓力降極大的情況下作降低介質(zhì)壓力之用。
介質(zhì)在節流閥瓣和閥座之間流速很大，以致使這些零件表面很快損壞－即所謂氣蝕現象。
為了盡量減少氣蝕影響，閥瓣采用耐氣蝕材料（合金鋼制造）并制成**角為140～180的流線(xiàn)型圓錐體，
這還能使閥瓣能有較大的開(kāi)啟*度，一般不**在小縫隙下節流。

的詳細介紹
**供應atos節流閥,阿托斯節流閥材質(zhì)
節流閥是通過(guò)改變節流截面或節流長(cháng)度以控制流體流量的閥門(mén)。
將節流閥和單向閥并聯(lián)則可組合成單向節流閥。
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
對節流閥的**要**：
·流量調節范圍大，流量一壓差變化平滑；
·內泄漏量小，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
·調節力矩小，動(dòng)作靈敏。
節流閥的外形結構與截止閥并無(wú)區別，只是它們啟閉件的形狀有所不同。
節流閥的啟閉件大多為圓錐流線(xiàn)型，通過(guò)它改變通道截面積而達到調節流量和壓力。
節流閥和單向節流閥是簡(jiǎn)易的流量控制閥，在定量泵液壓系統中，節流閥和溢流閥配合，
可組成三種節流調速系統，即進(jìn)油路節流調速系統、回油路節流調速系統和旁路節流調速系統。
節流閥沒(méi)有流量負反饋功能，不能補償由負載變化所造成的速度不穩定，
一般僅用于負載變化不大或對速度穩定性要求不*的場(chǎng)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,
