放料閥主要用于反應(yīng)釜、儲罐、和其他容器的底部排料、放料、取料和無死區(qū)關(guān)斷操作。借助于閥門底部法蘭焊接于儲罐或其他容器的底部,因此消除工藝介質(zhì)通常在容器出口的殘留現(xiàn)象,放料閥根據(jù)實(shí)際需求,閥底結(jié)構(gòu)設(shè)計為平底型,閥體結(jié)構(gòu)為Y型,并提供提升或下降兩種工作方式閥瓣。
密封副采用線密封,閥瓣密封根據(jù)需要可堆焊硬質(zhì)合金,使表面硬度達(dá)到HRC56-62,具有高耐磨、耐腐蝕的功能,保證密封的可靠性。
The discharge valve is mainly used for bottom discharge, discharge, retrieval, and dead zone free shutdown operations of reactors, storage tanks, and other containers. By welding the bottom flange of the valve to the bottom of the storage tank or other containers, the residual phenomenon of process medium at the outlet of the container is eliminated. The discharge valve is designed with a flat bottom structure and a Y-shaped valve body structure according to actual needs, and provides two working modes of lifting or lowering the valve disc.
The sealing pair adopts a line seal, and the valve disc seal can be welded with hard alloy as needed to achieve a surface hardness of HRC56-62. It has high wear resistance and corrosion resistance, ensuring the reliability of the seal.
1、可控放料,能精確控制放料量,實(shí)現(xiàn)定量定速放料。
2、閥體流道暢通,無殘留。
3、耐高溫耐腐蝕,密封副可堆焊硬質(zhì)合金,保護(hù)其不被沖刷、磨損,腐蝕。
4、結(jié)構(gòu)簡單可靠,結(jié)構(gòu)簡單使用,部件少,運(yùn)動部件為閥板的直線運(yùn)行,靠性高,使用壽命長,維護(hù)方便。
5、連接方式廣,可按實(shí)際工況需求定制弧形法蘭、平法蘭、焊接法蘭等。
6、優(yōu)化填料組設(shè)計,雙層調(diào)料設(shè)計可持續(xù)有效密封,延長使用壽命。
