襯氟截止閥，共分為三種結(jié)構(gòu)形式，分別是直流式、直通式、直角式。富銳可根據(jù)用戶實(shí)際工況需求，專業(yè)定制。驅(qū)動(dòng)方式多樣可選，手動(dòng)，氣動(dòng)，電動(dòng)均可。
富銳根據(jù)用戶反饋，工況介質(zhì)具有強(qiáng)腐蝕特性，富銳技術(shù)團(tuán)隊(duì)悉心研發(fā)鋼襯閥門用以應(yīng)對(duì)。采用氟塑料內(nèi)襯工藝，將腐蝕性介質(zhì)和金屬部件隔離，進(jìn)而實(shí)現(xiàn)閥門耐腐蝕的優(yōu)良特性。由于金屬部件不直接接觸介質(zhì)，采用普通碳鋼材料作為殼體，大大降低了閥體選材成本。
市場(chǎng)上目前常用的3種氟塑料內(nèi)襯材料PTFE、PFA和FEP， 我公司均能針對(duì)用戶實(shí)際工況，為用戶選擇經(jīng)濟(jì)、實(shí)用、穩(wěn)定的材料。三種材料都有極其優(yōu)良的耐腐蝕特性，但三者也存在差異。
PTFE，中文名稱：聚四氟乙烯，簡(jiǎn)稱F4, 又稱“塑料王”，是所有非金屬材料中耐腐蝕性能最良的材料，使用溫度可達(dá)250C，（當(dāng)然我司建議用戶在180C下，可長(zhǎng)期使用這種材料， 如果閥門長(zhǎng)期工作在180C以上，我司不建議使用該材料。）
PFA，中文名稱：可溶性聚四氟乙烯，該材料具備了上述PTFE所有的性能，而且相比PTFE具有更好的冷流性，所以該材料取代PTFE被廣泛的應(yīng)用于復(fù)雜結(jié)構(gòu)的閥門內(nèi)襯。
FEP，中文名稱：聚全氟乙丙烯, 簡(jiǎn)稱F46，同樣具有極其優(yōu)良的耐腐蝕性能和冷流性，相比以上材料，F(xiàn)46的使用溫度為120C，因此很多工況無(wú)法使用該材料，但是F46的經(jīng)濟(jì)實(shí)惠，是三者中的。對(duì)一些溫度要求不高的工況來(lái)說(shuō)，用戶的采購(gòu)使用成本大大降低。

Fluorine-lined globe valves are divided into three structural forms, namely direct-flow type, straight-through type, and right-angle type. Fortune can be professionally customized according to users' actual working conditions. Various drive modes are available, manual, pneumatic or electric.
According to user feedback, Fortune has strong corrosive properties in working conditions, and Fortune's technical team has carefully developed steel-lined valves to deal with it. The fluorine plastic lining process is used to completely isolate the corrosive medium and the metal parts, thereby realizing the excellent corrosion resistance of the valve. Since the metal parts do not directly contact the medium, ordinary carbon steel materials are used as the shell, which greatly reduces the cost of valve body selection.
At present, there are 3 kinds of fluoroplastic lining materials commonly used in the market: PTFE, PFA and FEP. Our company can choose economical, practical and stable materials for users according to the actual working conditions of users. All three materials have excellent corrosion resistance properties, but there are also differences among the three.
PTFE, Chinese name: Polytetrafluoroethylene, referred to as F4, also known as "Plastic King", is the material with the best corrosion resistance among all non-metallic materials, and the maximum use temperature can reach 250C. (Of course, our company recommends that users be at 180C This material can be used for a long time. If the valve works above 180C for a long time, our company does not recommend using this material.)
PFA, Chinese name: soluble polytetrafluoroethylene, this material has all the properties of the above-mentioned PTFE, and has better cold flow properties than PTFE, so this material replaces PTFE and is widely used in valve linings with complex structures.
FEP, Chinese name: Polyfluoroethylene propylene, referred to as F46, also has excellent corrosion resistance and cold flow properties. Compared with the above materials, the maximum operating temperature of F46 is 120C, so this material cannot be used in many working conditions, but The F46 is economical and the price is the most favorable among the three. For some working conditions with low temperature requirements, the user's purchase and use costs are greatly reduced.
