@ 产品特【tè】点 / Technical parameter
轴流式:是【shì】指流体到控【kòng】制区以前在【zài】阀的内体和 外体【tǐ】之间有【yǒu】一轴向对称的【de】流【liú】道 , 有【yǒu】呈流线【xiàn】型并均匀 对【duì】称【chēng】的自由【yóu】流通路径,大【dà】大降低了【le】流体局部【bù】高速流、 紊流、喷射流【liú】等的【de】冲击,且提高了阀门的稳定性。
“Axial flow”describes the in-line symmetrical flow path between the valve inner and outer body before the flow reaches the trim zone,with the free flow path was streamlined and symmetrical, reducing the local high speed flow of the fluid, turbulence,jet stream, such as shock, and to improve the stability of the valve.
1、轴流式调节阀【fá】具有光【guāng】滑流道的轴【zhóu】流式设计,使得【dé】阀【fá】门内部阻力很小,单位直径上的流通【tōng】能力非常强,同时 噪【zào】音【yīn】低,振动小。平衡【héng】阀芯【xīn】设计使得阀门所需扭矩【jǔ】与阀前【qián】后压【yā】差无关。阀体整体铸造减少了泄漏点,而且严 密性很【hěn】强,刚度【dù】好,阀【fá】门【mén】重【chóng】量很小。根【gēn】据用户工艺条件,优化套【tào】筒的设计,使得阀门的【de】控制范围便大,噪音降 低【dī】,控制能力加强。阀门操作可靠,并且可以长【zhǎng】时间无需维【wéi】护。
Axial flow design with smooth flow path which has less internal resistance, higher capacity, lower noise and less vibrations. The balanced plug design, results in a differential pressure independent of operating thrust. The overall casting body design minimises leakage points and valve weight, increase valve striltness and rigidity customer application optimised cage design results in low noise and good controllability with high rangeability. The robust construction provides a reliable operation for a long time and no need of maintenance.
2、轴【zhóu】流式调节阀坚固耐用,成【chéng】本【běn】低,高性能,优秀的设计使【shǐ】它在各种应【yīng】用场合的总效【xiào】率都非常高【gāo】。由于【yú】采用 轴【zhóu】向对称流道,完全【quán】避免【miǎn】了间接流和【hé】不必【bì】要流【liú】向的改变,因此,大大降低了噪音【yīn】和紊流的形成。轴流式设计 与传统设【shè】计相【xiàng】比,****限度地提高【gāo】了单位直径上的流通【tōng】能力。
Axial control valve is a rugged, low maintenance high performance valve, the design increase total efficiency over a wide range of control valve applications. The in-line and symmetrical flow path eliminates indirect flows and unnecessary changes in direction through the valve.
This results in significant reductions in noise and turbulence. The axial design provides the highest capacity per diameter compared to conventional designs.
3、轴【zhóu】流【liú】阀的【de】套【tào】筒四周均匀分【fèn】布小孔。这种设计【jì】的轴流式阀体保证流【liú】体均匀分布。通过套筒上的孔流出的流 体集中【zhōng】在阀门的径向,使【shǐ】流体阀门轴线上做冲击【jī】相互抵消,在【zài】不接【jiē】触阀体和阀门的其它部件的情况下,流 体本身的【de】能量在【zài】套【tào】筒【tǒng】内部消散,因此,减压是通过套筒来【lái】进【jìn】行的【de】。该设【shè】计控制流速【sù】,消除磨损和振动【dòng】 ,适合 天【tiān】然气和石油的控【kòng】制。
Axial control valves are equipped with a cage provided with multiple holes uniformly distributed over the full circumference. This design combined with the axial flow body concept ensures that the fluid is evenly distributed. The multitude of flow jets is diametrically opposed.
Consequently, the energy is dissipated in the centre of the valve by impingement. The energy dissipation is achieved in the fluid itself and in the cage and not near the body surface of any other valve component.Therefore the pressure con-version is done in a controlled manor in the area of the valve which is designed to do this. This design controlled velocity, eliminat-ing erosion and vibration are fit for gas andliquid applications.
