進口對夾式蝶閥產(chǎn)品列表德國洛克 

一、進口對夾式蝶閥產(chǎn)品簡介：

德國《LOCKE》洛克進口對夾式蝶閥結構簡單、體積小、重量輕，只由少數(shù)幾個零件組成。而且只需旋轉(zhuǎn)90°即可快速啟閉，操作簡單，同時該閥門具有良好的流體控制特性。蝶閥處于完全開啟位置時，蝶板厚度是介質(zhì)流經(jīng)閥體時唯一的阻力，因此通過該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。蝶閥有彈性軟密封和金屬密封兩種密封型式。

Locke butterfly valve imported from Germany is simple in structure, small in volume and light in weight, and only consists of a few parts. Moreover, the valve can be opened and closed quickly with only 90 ° rotation, and the operation is simple. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. There are two types of butterfly valve: elastic soft seal and metal seal.

8. The structure length is short, which is only 1 / 4 ~ 1 / 8 of the traditional flange check valve;

9. Small size, light weight, its weight is only 1 / 4 ~ 1 / 20 of the traditional flange check valve

三、進口對夾式蝶閥用途：

進口對夾式蝶閥用于硫酸行業(yè)中氣體管路：爐前鼓風機出入口，接力風機出入口，電除霧串聯(lián)及聯(lián)通閥，S02主鼓風機出入口，轉(zhuǎn)化器調(diào)節(jié)，預熱器出入口等調(diào)節(jié)和截止氣量使用。

用于硫磺制酸系統(tǒng)中的焚硫、轉(zhuǎn)化、干吸工段，是硫磺制酸裝置用閥的首選品牌，被廣大用戶認為是：密封性能好，運轉(zhuǎn)輕，副腐蝕，耐高溫，操作方便、靈活、使用安全可靠的蝶閥，得到了大量推廣使用。

還廣泛用于：化工、石化、冶煉、醫(yī)藥、食品等行業(yè)中SO2、蒸汽、空氣、煤氣、氨氣、CO2氣、油品、水、鹽水、堿液、海水、硝酸、鹽酸、硫酸、磷酸等介質(zhì)的管路上作為調(diào)節(jié)和截流裝置使用。

Imported wafer butterfly valve is used for gas pipeline in sulfuric acid industry: inlet and outlet of blower in front of furnace, inlet and outlet of relay fan, electric demist series and connecting valve, inlet and outlet of S02 main blower, converter regulation, inlet and outlet of preheater, etc. for regulation and cut-off gas volume.

The sulfur burning, conversion and dry absorption section used in the sulfur based sulfuric acid system is the preferred brand of valves for sulfur based sulfuric acid plant, which are considered by the majority of users as follows: butterfly valves with good sealing performance, light operation, auxiliary corrosion, high temperature resistance, convenient operation, flexibility, safe and reliable use, have been widely used.

It is also widely used in the pipeline of SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, alkali, sea water, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media in chemical, petrochemical, smelting, pharmaceutical, food and other industries as regulating and intercepting devices.
