@ 產(chǎn)品特點 / Technical parameter
軸流式:是指流體到控制區(qū)以前在閥的內(nèi)體和 外體之間有一軸向?qū)ΨQ的流道 , 有呈流線型并均勻 對稱的自由流通路徑,大大降低了流體局部高速流、 紊流、噴射流等的沖擊,且提高了閥門的穩(wěn)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、軸流式調(diào)節(jié)閥具有光滑流道的軸流式設(shè)計,使得閥門內(nèi)部阻力很小,單位直徑上的流通能力非常強,同時 噪音低,振動小。平衡閥芯設(shè)計使得閥門所需扭矩與閥前后壓差無關(guān)。閥體整體鑄造減少了泄漏點,而且嚴 密性很強,剛度好,閥門重量很小。根據(jù)用戶工藝條件,優(yōu)化套筒的設(shè)計,使得閥門的控制范圍便大,噪音降 低,控制能力加強。閥門操作可靠,并且可以長時間無需維護。
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、軸流式調(diào)節(jié)閥堅固耐用,成本低,高性能,優(yōu)秀的設(shè)計使它在各種應用場合的總效率都非常高。由于采用 軸向?qū)ΨQ流道,完全避免了間接流和不必要流向的改變,因此,大大降低了噪音和紊流的形成。軸流式設(shè)計 與傳統(tǒng)設(shè)計相比,****限度地提高了單位直徑上的流通能力。
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、軸流閥的套筒四周均勻分布小孔。這種設(shè)計的軸流式閥體保證流體均勻分布。通過套筒上的孔流出的流 體集中在閥門的徑向,使流體閥門軸線上做沖擊相互抵消,在不接觸閥體和閥門的其它部件的情況下,流 體本身的能量在套筒內(nèi)部消散,因此,減壓是通過套筒來進行的。該設(shè)計控制流速,消除磨損和振動 ,適合 天然氣和石油的控制。
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.
