产品介绍：WDSH系列内带集水仓的倒置桶过热蒸汽疏水阀专门用来克服过热，高压，小负荷等多种不力因素。集水仓存集足够的凝结水，保证在整个排放周期能够保持水封。密封的小杯在集水仓中起密封调节作用。

结构特点：

1、耐磨损，耐腐蚀，耐水击。

2、独特的杠杆机构将桶提供的力充分放大，可在系统压力下开启阀门。

3、排放孔通过水封保护可防止新鲜蒸汽泄漏。桶上的小孔可提供自动排空气。

4、倒置桶疏水阀不需要专门调节，凝结水不会存积造成水击。

安装建议：通常在过热高压小负荷工况下，在集水管和疏水阀内只是极少的凝结水产生。因此，选择适当的管道及集水管尺寸是正确使用过热蒸汽疏水阀的关键。

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.
