進口隔膜閥德國洛克各種參數以及說明

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F塑料，完全隔離介質與鋼件接觸，避免了閥體受腐蝕。

進口隔膜閥規格參數：

口徑大小：DN15A-1200A

溫度:0-1500℃

壓力:1.0-70.0Mpa。

連接方式:法蘭、螺紋、焊接、承插焊。

驅動方式:手動、氣動、電動、齒輪傳動等裝置。

材質選擇:不銹鋼、鑄鋼、碳鋼、鍛鋼、304、316等。

進口隔膜閥工作原理:

閥腔與閥瓣外表包襯F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F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。

進口隔膜閥產品簡介：

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F隔膜閥、進口氣動隔膜閥、進口無襯里隔膜閥、塑料隔膜閥。

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 flurine lined diaphragm valve, imported pneumatic diaphragm valve, imported unlined diaphragm valve and plastic diaphragm valve.
