閥門是在流體系統(tǒng)中，用來控制流體的方向、壓力、流量的裝置，是使配管和設(shè)備內(nèi)的介質(zhì)（液體、氣體、粉末）流動或停止并能控制其流量的裝置。閥門是管路流體輸送系統(tǒng)中控制部件，用來改變通路斷面和介質(zhì)流動方向，具有導(dǎo)流、截止、節(jié)流、止回、分流或溢流卸壓等功能。用于流體控制的閥門，從強(qiáng)簡單的截止閥到極為復(fù)雜的自控系統(tǒng)中所用的各種閥門，其品種和規(guī)格繁多，閥門的公稱通徑從極微小的儀表閥大至通徑達(dá)10m的工業(yè)管路用閥?？捎糜诳刂扑?、蒸汽、油品、氣體、泥漿、各種腐蝕性介質(zhì)、液態(tài)金屬和放射性流體等各種類型流體地流動，閥門的工作壓力可以從的超高壓，工作溫度可以c-270℃的**溫到1430℃的高溫。閥門的控制可采用多種傳動方式，如手動、電動、液動、氣動、渦輪、電磁動、電磁液動、電液動、氣液動、正齒輪、傘齒輪驅(qū)動等；可以在壓力、溫度或其它形式傳感信號的作用下，按預(yù)定的要求動作，或者不依賴傳感信號而進(jìn)行簡單的開啟或關(guān)閉，閥門依靠驅(qū)動或自動機(jī)構(gòu)使啟閉件作升降、滑移、旋擺或回轉(zhuǎn)運(yùn)動，從而改變其流道面積的大小以實現(xiàn)其控制功能。新疆黃銅絲扣排氣閥。</p><div

1.閥門的使用溫度閥門的使用溫度是由制造閥門的材質(zhì)所確定的。閥門常用材料的使用溫度如下：灰鑄鐵閥門使用溫度為—15～250℃；可鍛鑄鐵閥門使用溫度為—15～250℃；球墨鑄鐵閥門使用溫度為—30～350℃；高鎳鑄鐵閥門**高使用溫度為400℃；碳素鋼閥門使用溫度為—29～450℃，在JB/T3595—93標(biāo)準(zhǔn)推薦使用溫度t＜425℃；1Cr5Mo、合金鋼閥門**高使用溫度為550℃；12Cr1MoVA、合金鋼閥門**高使用溫度為570℃；1Cr18Ni9Ti、1Cr18Ni12Mo2Ti不銹鋼閥門使用溫度為—196～600℃；銅合金閥門使用溫度為—273～250℃；塑料閥門**高使用溫度：尼龍為100℃；氯化聚醚為100℃；聚氯乙烯為60℃；聚三氟氯乙烯—60～120℃；聚四氟乙烯—180～150℃。橡膠隔膜閥，因橡膠種類不同，其使用溫度各不相同；天然橡膠為60℃；丁腈橡膠、氯丁橡膠為80℃；氟橡膠為200℃；閥門襯里用橡膠、塑料時，以橡膠、塑料的耐溫性能為準(zhǔn)。陶瓷閥門，因其耐溫急變性差，一般用于150℃以下的工況條件。**近出現(xiàn)一種超性能陶瓷閥門，能耐1000℃以下的高溫。玻璃閥門，耐溫急變性差，一般用于90℃以下的工況條件。搪瓷閥門，耐溫性能受到密封圈材料的限制，**高使用溫度不超過150℃。鑄鋼球閥價格鑄鋼球閥批發(fā)
