進口隔膜閥德國洛克品牌值得擁有 

進口隔膜閥結構特點:

隔膜連接件少，整體鋼性好。

截流速度快，阻力小

開啟限位方便、靈活、精確。

閥體整體結構比較小，便于安裝和維修。

閥腔與閥瓣外表包襯氟塑料，完全隔離介質與鋼件接觸，避免了閥體受腐蝕。

進口隔膜閥工作原理:

閥腔與閥瓣外表包襯氟塑料，完全隔離介質與鋼件接觸，避免了閥體受腐蝕。

隔膜閥用耐腐蝕襯里的閥體和耐腐蝕隔膜代替閥芯組件，利用隔膜的移動起調節(jié)作用。隔膜閥的閥體材料采用鑄鐵、鑄鋼，或鑄造不銹鋼，并襯以各種耐腐蝕或耐磨材料、隔膜材料橡膠及聚四氟乙烯。襯里的隔膜耐腐蝕性能強，適用于強酸、強堿等強腐蝕性介質的調節(jié)。

Working principle of imported diaphragm valve:
The outer surface of valve cavity and disc is lined with fluoroplastics to completely isolate the medium from contacting with steel parts, so as to avoid corrosion of valve body.
Diaphragm valve with corrosion-resistant lining of the valve body and corrosion-resistant diaphragm instead of valve core components, the use of diaphragm movement adjustment. The valve body of diaphragm valve is made of cast iron, cast steel or cast stainless steel, lined with various corrosion-resistant or wear-resistant materials, diaphragm material rubber and polytetrafluoroethylene. The lining diaphragm has strong corrosion resistance and is suitable for the adjustment of strong corrosive media such as strong acid and strong alkali.

德國洛克 《DE LOCKE 》進口隔膜閥是用隔膜作啟閉件封閉流道、截斷流體、并將閥體內腔和閥蓋內腔隔開的截止閥。隔膜常用橡膠、塑料等彈性、耐腐蝕、非滲透性材料制成。 閥體多用塑料、玻璃鋼、陶瓷或金屬襯膠材料制成。 結構簡單、密封和防腐性能較好，流體阻力小。用于 低壓、低溫、腐蝕性較強和含懸浮物質的介質。常用的隔膜閥有進口襯膠隔膜閥、進口襯氟隔膜閥、進口氣動隔膜閥、進口無襯里隔膜閥、塑料隔膜閥。

Introduction of imported diaphragm valve products:
German Locke "de Locke" imported diaphragm valve is a shut-off valve which uses diaphragm as the opening and closing part to close the flow channel, cut off the fluid and separate the inner cavity of valve body and the inner cavity of valve cover. The diaphragm is usually made of elastic, corrosion-resistant and impermeable materials such as rubber and plastic. The valve body is made of plastic, glass fiber reinforced plastic, ceramic or metal lining material. It has the advantages of simple structure, good sealing and anti-corrosion performance and low fluid resistance. It is used for low pressure, low temperature, corrosive and medium containing suspended substance. Commonly used diaphragm valves are imported rubber lined diaphragm valve, imported fluorine lined diaphragm valve, imported pneumatic diaphragm valve, imported unlined diaphragm valve and plastic diaphragm valve.
