进口隔膜阀(德国OLES奥莱斯阀门)

【进口隔膜阀】详细说明：

Detailed description of imported diaphragm valve：

隔膜阀是一种特殊形式的具有截断功能的阀门，其启闭件由钢质阀瓣与软质材料（橡胶和氟塑料复合）制成的隔膜组成，并将阀体内腔隔开以达到截断管内介质之目的。

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.

【进口隔膜阀】基本结构：

1、复合隔膜将阀体下部腔与阀盖内腔隔开，并与之形成直流通道，使隔膜上部的阀杆，阀瓣等内件与介质*隔离，省去填料密封结构，介质的内漏和外漏可同时避免。

2、做为执行元件的膜件由于频繁的启闭易产生疲劳断裂，应视工况，介质特性进行定期更换。

3、塑料的防腐性能及*使用温度见“阀门及管路附件塑料衬里性能表。”

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".

【进口隔膜阀】特点：

1、采用橡胶或塑料等软质密封制作的隔膜，密封性较好。由于隔膜为易损件，应视介质特性而定期更换。

2、受隔膜材料限制，隔膜阀适用于低压和温度相对不高的场合。 

3、隔膜阀按结构形式可分为：屋式隔膜阀、直流式隔膜阀、截止式隔膜阀、直通式隔膜阀、闸板式隔膜阀和直角式隔膜阀六种；连接形式通常为法兰连接；按驱动方式可分为手动、电动和气动三种，其中气动驱动又分为常开式、常闭式和往复式三种一、

【进口隔膜阀】结构特点：

隔膜阀是一种特殊形式的截止阀：

1. 弹性密封的开闭件，确保没有内漏；

2. 流线型的流道，使得压力损失小；

3. 没有填料函，因此没有外漏；

4. 阀体与盖被中间隔膜隔开，使得隔膜上方的阀盖，阀杆等零件不受介质侵蚀;

5. 隔膜可更换，维护费用低；

6. 衬里材料的多样性，可适用于各种介质，并具有强度高、耐腐蚀性能好的特点。
