進口襯氟球閥德國洛克為世界造好閥

進口襯氟球閥結構特點：

①采用FEP襯里層的球閥,具有極高的化學穩(wěn)定性,可以適用除"熔融堿金屬和元素氟"，以外其它任何強腐蝕性質(zhì);

②采用全通徑、浮動球結構，閥門可在整個壓力范圍內(nèi)進行無泄漏關閉，更便于管路系統(tǒng)的通球掃線和管路維護;

③啟閉件球件與閥桿鑄(鍛)為一體，杜絕了由于壓力變化引起閥桿沖出承壓件內(nèi)的可能性，從根本上保證了工程中的使用安全性;

④結構緊湊合理，閥體內(nèi)腔空間最小，減小了介質(zhì)滯留，另外，特殊的模壓工藝，使密封面致密度良好，加之人字環(huán)形PTFE填料組合，使閥門達到零泄漏。

Structural features of imported flurine lined ball valve:

① The ball valve with FEP lining layer has high chemical stability and can be applied to any strong corrosion property except "molten alkali metal and element flurine";

② With full bore and floating ball structure, the valve can be closed without leakage in the whole pressure range, which is more convenient for ball cleaning and pipeline maintenance of pipeline system;

③ The ball part of the opening and closing part and the valve rod are cast (forged) as a whole, which eliminates the possibility that the valve rod can be pushed out of the pressure bearing parts due to the pressure change, and fundamentally ensures the safety of the use in the project;

④ The structure is compact and reasonable, and the inner cavity space of the valve body is the smallest, which reduces the medium retention. In addition, the special molding technology makes the sealing surface have good density, and the herringbone ring PTFE packing combination makes the valve achieve zero leakage.

進口襯氟球閥規(guī)格參數(shù)：

1.設計規(guī)范：遵循GB 12237，API 608，API 6D

2.驅(qū)動方式：手動、蝸輪傳動、氣動、電動。

3.公稱壓力：PN1.0～2.5(MPa)

4.公稱通徑：DN15～350mm

進口襯氟球閥工作原理：

襯氟球閥是用帶圓形通孔的球體作啟閉件，球體隨閥桿繞閥體中心線旋轉(zhuǎn)以實現(xiàn)閥門開啟和關閉。采用特殊的模壓工藝，使密封面致密良好，加之V型PTFE填料組合使閥門達到零泄漏；球體與閥桿鑄為一體，杜絕了由于壓力變化引起閥桿沖出承壓件內(nèi)的可能性，根本保證使用中的安全性；采用全塑料襯里工藝，耐介質(zhì)的強腐蝕。

襯氟球閥閥體內(nèi)腔及碟板均采用高壓注塑工藝襯有耐腐蝕、耐老化的聚全氟乙炳烯，故具有可靠的耐腐蝕性和密封性。主要用于對生產(chǎn)過程中酸堿等強腐蝕介質(zhì)的調(diào)節(jié)或切斷。

進口襯氟球閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進口襯氟球閥采用氟塑料作為內(nèi)襯，帶桿球體結構，獨特的彈性唇式密封閥座，采用燕尾槽耐負壓，填料函閥體內(nèi)設計，能在大壓差和較大溫差范圍內(nèi)具有高密封性能和扭拒輕的功能。
