          螺紋靜態平衡閥

          靜態平衡閥
          Static Balancing Valves

           

          在定流量系統中,靜態失衡現象可用靜態平衡閥或動態平衡閥來解決,在主管及每個支管安裝靜態平衡閥或定流量平衡閥對壓力和流量進行控制,保證每一個支管維持適合的工況來滿足供熱及制冷的需求。

          In a fixed rate system, the static unbalance can be solved by installing static balancing valves and dynamic fixed flow balancing valves,in main pipes and every sub-pipes in system,which ensures every sub-pipes to sustain appropriate conditions to meet the healing and cooling demands.

           

          l         概述 Description

          靜態平衡閥是通過改變閥芯與閥座的開度,來改變流經閥門的流動阻力,以達到調節流量的目的,靜態平衡閥的開度不會因閥門前后壓差變化而改變,通過閥門的流量隨壓差的變化而變化。所以使用靜態平衡閥只能解決靜態失衡問題,而不能解決動態失衡問題。

           

          Static balancing valve is by changing the valve core and the open seat, to change the resistance to flow through valves, so as to achieve the purpose of flow adjustment, static balance valves and valve by differential pressure across the valve changed, the differential pressure flow with the changes. So using static unbalance balancing valve can solve problems, but not the static unbalance of dynamic.

          l        特點Characteristics

          靜態水力平衡聯調,保證系統調試后末端設備的流量同時達到設計流量,系統能均衡地輸送足夠的水量到各個末端設備。首先將系統分解成一個多級的多個并聯子系統,然后按照從末端到主機的順序,對各個并聯子系統按照一定的步驟進行調節,使其各支路流量比與設計要求流量比值一致,最后調整系統主管的流量至設計總流量 ,這時系統中各個末端設備的流量 同時達到設計流量。

          Static hydraulic balancing united adjustment can ensure the flow rate of terminal equipments to reach designing flow rate after the adjustment of system.the system can balancedly transport water to every terminal equipments.firstly the system is divided into many parallel subsystems,and then the parallel subsystems will be adjusted with the order from the terminal to the main parts to make the flow rate ratio of subflow in accordance with the designing flow rate ratio.Finally the flow rate of main system is adjusted to total designing flow rate,thus the flow rate of every terminal equipments will reach the designing flow rate simultaneously.

          l         安裝說明: Installation Instructions

          安裝時,閥體上的箭頭必須與實際水流方向一致,閥門的進出水端應安裝一段長度為15倍該管徑的直管。選擇的預設定值可通過兩部分刻度盤來完成,即粗調刻度盤與精調刻度盤。

          The arrow direction on the switch has to be consistent with the direction of the flow.A straight pipe 15 times longer than the diameter of the pipe has to be installed in the inlet and outlet of the valves.The preset can be done by two calibrated dials,a coarse adjustment calibrated dial and a fine adjustment calibrated dial.
