**供应atos节流阀,阿托斯节流阀材质
节流阀是通过改变节流截面或节流长度以控制流体流量的阀门。
将节流阀和单向阀并联则可组合成单向节流阀。
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
对节流阀的**要**：
·流量调节范围大，流量一压差变化平滑；
·内泄漏量小，若有外泄漏油口，外泄漏量也要小；
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
·调节力矩小，动作灵敏。
节流阀的外形结构与截止阀并无区别，只是它们启闭件的形状有所不同。
节流阀的启闭件大多为圆锥流线型，通过它改变通道截面积而达到调节流量和压力。
节流阀和单向节流阀是简易的流量控制阀，在定量泵液压系统中，节流阀和溢流阀配合，
可组成三种节流调速系统，即进油路节流调速系统、回油路节流调速系统和旁路节流调速系统。
节流阀没有流量负反馈功能，不能补偿由负载变化所造成的速度不稳定，
一般仅用于负载变化不大或对速度稳定性要求不*的场合。
**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,
