德國LOCKE洛克進(jìn)口電動陶瓷調(diào)節(jié)閥采用三段式結(jié)構(gòu)，其主要由陶瓷球閥與電子式電動執(zhí)行機(jī)構(gòu)組合而成，根據(jù)不同的現(xiàn)場工況運用不同的鍛件材質(zhì)（碳鋼或不銹鋼），使閥體材質(zhì)的結(jié)構(gòu)更加合理。閥門內(nèi)部材質(zhì)與介質(zhì)接觸部分均采用結(jié)構(gòu)陶瓷材料，避免與介質(zhì)直接接觸，而產(chǎn)生腐蝕的可能。結(jié)構(gòu)陶瓷化學(xué)性能穩(wěn)定，硬度高，可耐絕大部分酸堿介質(zhì)腐蝕，并且具有極好的耐磨性能。廣泛應(yīng)用于電廠的煙氣脫硫系統(tǒng)、除渣系統(tǒng)以及燃燒系統(tǒng)；堿廠的鹽水系統(tǒng)、蒸餾系統(tǒng)；造紙廠的紙漿控制系統(tǒng)等。尤其是在電站脫硫（FGD）工程中，陶瓷閥很好地解決了FGD工況存在的高氯離子腐蝕，高固含量磨損兩大問題。在石灰石漿液、石膏漿液廢水的調(diào)節(jié)過程中德國LOCKE洛克進(jìn)口陶瓷調(diào)節(jié)閥是目前最理想的閥門。

Germany locke imported electric ceramic control valve adopts three-stage structure, which is mainly composed of ceramic ball valve and electronic electric actuator. According to different field conditions, different forging materials (carbon steel or stainless steel) are used to make the structure of valve body material more reasonable. The internal material of the valve and the contact part of the medium are made of structural ceramic material, so as to avoid the possibility of direct contact with the medium and produce corrosion. The structural ceramics have stable chemical properties, high hardness, corrosion resistance in most acid and alkali media, and excellent wear resistance. It is widely used in flue gas desulfurization system, slag removal system and combustion system of power plant, brine system and distillation system of alkali plant, pulp control system of paper mill, etc. Especially in the FGD project, the ceramic valve can solve the two problems of high chloride ion corrosion and high solid content wear. In the regulation process of limestone slurry and gypsum slurry wastewater, the ceramic control valve imported from Germany Locke is the most ideal valve at present.
