品牌進(jìn)口隔膜閥認(rèn)準(zhǔn)德國洛克 

一、進(jìn)口隔膜閥結(jié)構(gòu)優(yōu)點：

1.彈性密封的開閉件，確保沒有內(nèi)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.閥體與閥蓋被中間隔膜隔開，使的隔膜上方的閥蓋、閥桿等零件不受介質(zhì)侵蝕；

5.隔膜可更換，維護(hù)費用低；

6.襯里材料多樣可選性，可適用于各種介質(zhì)，并具有良好的耐腐蝕性；

1. The opening and closing parts of elastic seal shall be free of internal leakage;

2. Streamlined flow channel, making the pressure loss small;

3. There is no stuffing box, so there is no leakage;

4. The valve body and the valve cover are separated by the middle diaphragm, so that the valve cover, valve stem and other parts above the diaphragm are not eroded by the medium;

5. The diaphragm can be replaced with low maintenance cost;

6. The lining materials are various and optional, applicable to various media, and have good corrosion resistance;

二、進(jìn)口隔膜閥描述：

德國《LOCKE》洛克進(jìn)口隔膜閥的結(jié)構(gòu)分為堰式隔膜閥、直流式隔膜閥、直通式隔膜閥和三通式隔膜閥,是一種特殊形式的截斷閥,它的啟閉件是一塊用軟質(zhì)材料制成的隔膜，把閥體內(nèi)腔與閥蓋內(nèi)腔及驅(qū)動部件隔開,用于控制非腐蝕性或一般腐蝕性以及強(qiáng)腐蝕性介質(zhì)，閥體內(nèi)腔表面無襯里或覆有可選擇的各種氟塑料和各種橡膠，適用于各種不同工作溫度和流體管路。

The structure of Locke imported diaphragm valve is divided into weir diaphragm valve, direct flow diaphragm valve, through diaphragm valve and three-way diaphragm valve. It is a special type block valve. Its opening and closing parts are a diaphragm made of soft materials, which separates the inner cavity of valve body from the inner cavity of valve cover and driving parts, It is used to control non corrosive or general corrosive and strong corrosive media. The inner surface of the valve body is unlined or covered with optional fluoroplastics and rubbers. It is suitable for various working temperatures and fluid pipelines.
