一、不銹鋼直通式襯氟截止閥產(chǎn)品簡(jiǎn)介：

手動(dòng)、法蘭連接、直通式、閥座密封面材料為氟塑料、公稱壓力 PN1.0-10.0MPa、閥體材料有鑄鋼、鑄鐵、不銹鋼的截止閥。不銹鋼直通式襯氟截止閥是指啟閉件（閥瓣）由閥桿帶動(dòng)并沿閥座中心軸線做升降運(yùn)動(dòng)的閥門，是一種常用的截?cái)嚅y，主要用來接通或截?cái)喙苈分械慕橘|(zhì)，一般不用于調(diào)節(jié)流量。

二、不銹鋼直通式襯氟截止閥結(jié)構(gòu)特點(diǎn)：

1、  與閘閥相比，截止閥的結(jié)構(gòu)較簡(jiǎn)單，制造與維修都較方便。

2、  密封面不易磨損、擦傷，密封性較好、壽命長(zhǎng)。

3、  啟閉時(shí)閥瓣行程較小，啟閉時(shí)間較短、閥門高度較小。

4、  閥瓣與閥桿設(shè)計(jì)為一體結(jié)構(gòu)，結(jié)構(gòu)緊湊，使用安全。

5、  截止閥有三種結(jié)構(gòu)形式：直通式、直流式、角式，其中直通式最為常用，角式可以安裝在管路系統(tǒng)的拐角處，直流式流阻是截止閥中最小的。

6、  可根據(jù)用戶需求配置氣動(dòng)、電動(dòng)裝置，滿足遙控和程控的需要。

7、  更換零件襯里材料可適用各種介質(zhì)。

三、不銹鋼直通式襯氟截止閥技術(shù)參數(shù)及執(zhí)行標(biāo)準(zhǔn)：
