VPS 靜態平衡閥 - 安裝說明
應用
靜態平衡是通過預設的開度位置來完成的。選擇的預設值能從2圈開度指示上來 讀取（基本圈數和精確到 / 0圈的顯示）。平衡閥有兩個螺紋部位可以連接絲 堵球閥或壓差測量裝置。交貨時，DN 5-50配置測量接頭，DN65及以上安裝2個 盲絲堵，包裝袋內提供測量接頭以現場更換。此平衡閥既可安裝在供水管上， 也可以安裝在回水管上，一般安裝在回水管上。
收貨與存儲
收貨時需檢驗閥門是否在運輸過程中有損壞。小心將閥門放置到地面上。需要 吊裝時，務必緊固閥體，禁止吊裝任何青銅或不銹鋼內件。
閥門安裝前需要保持清潔、干燥。如果超過6個月的長時間存儲，建議閥座密封 面涂覆一層食品級的油脂。禁止將橡膠內件暴露在陽光或臭氧環境中。
安裝
閥門必須安裝在相同規格的管道上，必須保證接介質流向同閥體上箭頭的方向 一致。
建議按下圖所示安裝。為保證流量測量的準確性，必須保證閥門的進出口端擁 有足夠長度的直管道。進口端直管道的長度不少于5倍的閥門公稱通徑，出口端 直管道的長度不少于2倍的閥門公稱通徑。如果閥門安裝在泵的出口端，泵出口 與閥門進口端之間的直管道長度不少于 0倍閥門公稱通徑。
Application
Static balance is achieved by pre-setting of opening position,which could be read by scale on two circles (one for basic circle and another for fine adjustable circle). DN 5-50 valves have two pressure testing connectors, while DN65 and above have two plugs on the valves, two testing connectors in the package to be replaced on jobsite. The valves may be installed in either the supply or the return pipe, and normally on the return pipe.
Inspection And Storage
Inspect valves while receiving the valve. Put all valves carefully on the ground. When lifting, the valve should be tightly secured and never lifted by the bronze or stainless steel trim.
The valves should keep clean and dry before installation. If storage period more than six months, the surfaces of the seat (when provided) should be coated with a thin film of FDA approved grease. Do not expose rubber seat to sunlight or ozone.
Installation
The flow arrow on the valve must be the same to the flow direction in the pipe system.
The valve must be installed in a run of pipe of the same nominal size. All valves are recommended to be installed as fig below. To ensure flow measurement accuracy it
is essential that the piping on the inlet and outlet sides is straight and has a minimum length equivalent to 5 diameters at inlet and 2 diameters at outlet as shown. If the valve is located on the outlet from a pump then it is essential that the straight pipe length between pump outlet and valve inlet is a minimum of 0 diameters.
維修
平衡閥不需要常規的日常維護。如果閥桿與壓蘭之間有泄漏，可以擰緊一下壓 蘭填料。拆下手輪鎖母，去掉手輪。按要求擰緊壓蘭螺栓。不要過度擰緊以免 影響正常操作。（閥門沒有上密封功能，不能帶壓去除壓蘭）。重新安裝手 輪，檢查閥門是否正常操作，是否有泄漏。
Maintenance
No routine maintenance is required. It is possible to tighten the gland while leakage happen between stem and gland Unscrew the hand wheel nut, remove the hand wheel, tighten the gland screw. (The valves are not provided with top sealing. Removing gland without relieving the presssure is prohibited.) Reinstall the hand wheel, check the valve for smooth operating and no leakage. |
