Construction is relatively simple, easy to manufacture and maintenance, low cost.
Adjustment accuracy is not high, can not be used for adjustment.
Throttle valve no flow negative feedback function,
can not compensate for the load caused by the instability caused by the speed,
Generally only for the load changes little or less stability requirements of the occasion.
The shape of the throttle valve and cut-off valve is no different,
but they are different from the shape of the opening and closing parts.
Throttle valve opening and closing parts are mostly conical streamlined,
through which to change the channel cross-sectional area to adjust the flow and pressure
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,外泄漏量也要小;
##壓力可達(dá)350bar
節(jié)流閥是通過改變節(jié)流截面或節(jié)流長(zhǎng)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。
密封面易沖蝕,不能作切斷介質(zhì)用。
與ISO標(biāo)準(zhǔn)電磁閥疊加安裝在一起
常規(guī)閥品種齊全,壓力、流量、方向控制所有基本功能型式均供貨,
安裝方式多樣選擇, 板式、螺紋安裝或法蘭安裝均供貨
##流量可達(dá)600 l/min
And made the top angle of 140 to 180 streamlined cone,
This can also make the valve flap can have a large opening height,
generally not recommended in the small gap under the throttling.
節(jié)流閥和單向節(jié)流閥是簡(jiǎn)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(jié)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(xiàn)象。
Stack valve in line with ISO standards, the full range, precision design,
