進(jìn)口內(nèi)螺紋隔膜閥德國洛克供應(yīng)各種規(guī)格

 

進(jìn)口內(nèi)螺紋隔膜閥結(jié)構(gòu)特點(diǎn)：

1、無填料函，節(jié)流元件為彈性隔膜，可以做到關(guān)閉時無內(nèi)外漏，適用于不允許污染及危險禁區(qū)場合。

2、流路平滑，流阻小，具有很大的流通能力，適用于高濃度及帶有纖維介質(zhì)懸浮液中。

3、鋁合金壓鑄的外殼、活塞型的設(shè)計結(jié)構(gòu)使其外表更精美、體積小、重量輕、輸出力大

4、偏氟塑料的閥體和聚四氟乙烯的隔膜使其耐腐蝕性能更強(qiáng)、工作壽命更長，適用于酸堿、腐蝕性介質(zhì)。

進(jìn)口內(nèi)螺紋隔膜閥工作原理：

隔膜閥的密封原理是靠操作機(jī)構(gòu)的向下運(yùn)動壓下隔膜或隔膜組合件與堰式的襯里閥體或直通式襯里閥體的通道相密合,使之達(dá)到密封。密封比壓的大小靠關(guān)閉件向下的壓力大小來實現(xiàn)。由于閥體可以襯各種軟質(zhì)材料,如橡膠或聚四氟乙烯等;隔膜也是軟質(zhì)材料制成,如橡膠或合成橡膠襯里的聚四氟乙烯,故用較小的密封力就能達(dá)到完全密封。 隔膜閥只有閥體、隔膜和閥蓋組合件三個主要部件。隔膜把下部閥體內(nèi)腔與上部閥蓋內(nèi)腔隔開,使位于隔膜上方的閥桿、閥桿螺母、閥瓣、氣動控制機(jī)構(gòu)、電動控制機(jī)構(gòu)等零部件不與介質(zhì)接觸,且不會產(chǎn)生介質(zhì)外漏,省去了填料函的密封結(jié)構(gòu)。

Working principle of imported internal thread diaphragm valve:
The sealing principle of diaphragm valve is to press down the diaphragm or diaphragm assembly by the downward movement of the operating mechanism and close the channel of weir type lined valve body or straight through type lined valve body to achieve sealing. The sealing pressure depends on the downward pressure of the closing part. Because the valve body can be lined with various soft materials, such as rubber or polytetrafluoroethylene, and the diaphragm is also made of soft materials, such as polytetrafluoroethylene lined with rubber or synthetic rubber, it can be completely sealed with less sealing force. Diaphragm valve has only three main parts: valve body, diaphragm and bonnet assembly. The diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, valve stem nut, valve disc, pneumatic control mechanism, electric control mechanism and other parts above the diaphragm are not in contact with the medium, and the medium leakage will not occur, thus eliminating the sealing structure of the stuffing box.
