進口隔膜閥(德國OLES奧萊斯閥門)

【進口隔膜閥】詳細說明：

Detailed description of imported diaphragm valve：

隔膜閥是一種特殊形式的具有截斷功能的閥門，其啟閉件由鋼質閥瓣與軟質材料（橡膠和氟塑料復合）制成的隔膜組成，并將閥體內腔隔開以達到截斷管內介質之目的。

Diaphragm valve is a special type of valve with truncation function. Its opening and closing parts are composed of steel disc and diaphragm made of soft materials (rubber and fluoroplastics), and the inner cavity of the valve is separated to achieve the purpose of truncating the medium in the pipe.

【進口隔膜閥】基本結構：

1、復合隔膜將閥體下部腔與閥蓋內腔隔開，并與之形成直流通道，使隔膜上部的閥桿，閥瓣等內件與介質*隔離，省去填料密封結構，介質的內漏和外漏可同時避免。

2、做為執行元件的膜件由于頻繁的啟閉易產生疲勞斷裂，應視工況，介質特性進行定期更換。

3、塑料的防腐性能及*使用溫度見“閥門及管路附件塑料襯里性能表。”

1The composite diaphragm separates the lower chamber of the valve body from the inner chamber of the valve cover, and forms a direct current channel with it, so that the inner parts such as the stem and disc on the upper part of the diaphragm are completely isolated from the medium, eliminating the packing sealing structure, and the leakage and leakage of the medium can be avoided at the same time.

2. Membranes as actuators are prone to fatigue fracture due to frequent opening and closing. Medium properties should be replaced regularly according to working conditions.

3. For the anticorrosion performance and recommended temperature of plastics, see "Performance Table of Plastic Lining for Valves and Pipeline Accessories".

【進口隔膜閥】特點：

1、采用橡膠或塑料等軟質密封制作的隔膜，密封性較好。由于隔膜為易損件，應視介質特性而定期更換。

2、受隔膜材料限制，隔膜閥適用于低壓和溫度相對不高的場合。 

3、隔膜閥按結構形式可分為：屋式隔膜閥、直流式隔膜閥、截止式隔膜閥、直通式隔膜閥、閘板式隔膜閥和直角式隔膜閥六種；連接形式通常為法蘭連接；按驅動方式可分為手動、電動和氣動三種，其中氣動驅動又分為常開式、常閉式和往復式三種一、

【進口隔膜閥】結構特點：

隔膜閥是一種特殊形式的截止閥：

1. 彈性密封的開閉件，確保沒有內漏；

2. 流線型的流道，使得壓力損失小；

3. 沒有填料函，因此沒有外漏；

4. 閥體與蓋被中間隔膜隔開，使得隔膜上方的閥蓋，閥桿等零件不受介質侵蝕;

5. 隔膜可更換，維護費用低；

6. 襯里材料的多樣性，可適用于各種介質，并具有強度高、耐腐蝕性能好的特點。
