復合式過熱蒸汽疏水閥 Combined overheated sream trap
產品介紹：SH系列內帶集水倉的倒置桶過熱蒸汽疏水閥專門用來克服過熱，高壓，小負荷等多種不力因素。集水倉存集足夠的凝結水，保證在整個排放周期能夠保持水封。密封的小杯在集水倉中起密封調節作用。
結構特點：
1、耐磨損，耐腐蝕，耐水擊。
2、*的杠桿機構將桶提供的力充分放大，可在系統壓力下開啟閥門。
3、排放孔通過水封保護可防止新鮮蒸汽泄漏。桶上的小孔可提供自動排空氣。
4、倒置桶疏水閥不需要專門調節，凝結水不會存積造成水擊。
安裝建議：通常在過熱高壓小負荷工況下，在集水管和疏水閥內只是極少的凝結水產生。因此，選擇適當的管道及集水管尺寸是正確使用過熱蒸汽疏水閥的關鍵。
Introduction：SH inverted bucket steam trap is especially designed to solve the problems of overheating,high pressure and small load.The sufficient condensed water stored in the water storage chamber can ensure the sealing during the whole period of discharging .The small cup play adjustable role in water storage chamber.
Structure：1.Boasting excellent abilities to resist abrasiveness，corruption and water
2.Unique lever structure will fully magnify the power provided by bucket.The valve will be opened under system pressure ;
3.Discharging pore which is sealed can protect the fresh steam from leakge.The pore on the bucket can provide automatic gas discharging.
4.The inverted bucket trap does not need special adjustment and the condensed water will not be stored to cause water beating.
Suggestions：on installation ：Under the overheated pressure,there’s little condensed water produced in the catchment pipelines and trap.Therefore,to choose appropriate pipelines and size of catchment pipelines is the key to correctly use the overheated trap.

| 故障現象 | 可能原因 | 解決方法 |
| 漏汽 | 1 ．閥片、閥座的密封面嚴重磨損； | 研磨密封面，使其達到密封； |
| 2 ．密封面上存有污垢或水銹 | 打開閥蓋清除污垢或水銹 | |
| 3 ．閥前無凝結水、蒸汽過熱 | 關閉疏水閥前截止閥 | |
| 連續排水 | 閥蓋沒有擰緊或者閥蓋有泄漏蒸汽直接進入控制，使閥片打不開。 | 旋緊閥蓋或排除泄漏處，可用耐高溫密封膠修補泄漏處 |
