(1)旋塞閥流體直流通過，阻力小，啟閉方便。.迅速。
(1) The plug valve has direct flow of fluid, low resistance, and convenient opening and closing Quickly.
在管道中，旋塞閥主要用于切斷管道.升級和改變介質的流動方向。新疆閥門生產廠家說它很容易適應多通道結構，甚至一個閥門可以得到兩個。.三個.即使是四種不同的流道，也能簡化管道系統的設計，減少閥門用量和設備中所需的一些連接件。
In pipelines, plug valves are mainly used to cut off pipelines, upgrade and change the flow direction of the medium. The valve manufacturer in Xinjiang said that it is easy to adapt to a multi-channel structure, and even one valve can obtain two Three. Even with four different flow channels, it can simplify the design of pipeline systems, reduce valve usage, and require some connectors in equipment.
(3)旋塞閥是歷史上的一種早些時候被人們使用的閥門。因其結構簡單，開合迅速(塞旋轉1/4)Q圓圈可以完成開合動作)，操作方便，流體阻力小，至今仍被廣泛使用。主要用于低壓、小直徑、低介質溫度。
(3) Plug valve is a type of valve that was used earlier in history. Due to its simple structure, fast opening and closing (plug rotates 1/4), easy operation, and low fluid resistance, it is still widely used today. Mainly used for low pressure, small diameter, and low medium temperature.
根據旋塞閥的結構特點和設計所能達到的功能，可按以下原則選擇。
According to the structural characteristics and design capabilities of the plug valve, the following principles can be followed for selection.
①說用來分配介質，改變介質的流動方向，其工作溫度不超過300℃，公稱壓力PN≤1.6MPa.公稱通徑不超過3000mm，推薦選擇多通道旋塞閥。
① It is used to distribute media and change the flow direction of the media, with a working temperature not exceeding 300 ℃ and a nominal pressure PN ≤ 1.6MPa. The nominal diameter does not exceed 3000mm. It is recommended to choose a multi-channel plug valve.
②牛奶.果汁.建議選擇奧氏體不銹鋼、緊定式圓錐形旋塞閥等食品企業和制藥廠等設備和管道。
② Milk and fruit juice. It is recommended to choose equipment and pipelines such as austenitic stainless steel, tight set conical plug valves, and other food enterprises and pharmaceutical factories.
③油田開采.開采天然氣田.管道輸送支管.在精煉和清潔設備中，公稱壓力級不大于Class300.公稱不超過300mm，推薦使用油封圓錐旋塞閥。
③ In oil field exploration, natural gas field extraction, pipeline transportation branches, and refining and cleaning equipment, the nominal pressure level should not exceed Class300 and the nominal pressure should not exceed 300mm. It is recommended to use oil sealed conical plug valves.
④烏魯木齊閥門生產廠家說油田開采.天然氣開采.管道輸送支管.在精煉和清潔設備中，公稱壓力級不大于Class公稱通徑不超過9000mm.工作溫度不超過3400℃，推薦使用油封圓錐旋塞閥。
④ The valve manufacturer in Urumqi said that in oil field exploration, natural gas exploration, pipeline transportation branch pipes, and refining and cleaning equipment, the nominal pressure level should not exceed Class, the nominal diameter should not exceed 9000mm, and the working temperature should not exceed 3400 ℃. It is recommended to use oil sealed conical plug valves.
⑤在大型化工行業，在含有腐蝕性介質的管道和設備中，需要快速打開或關閉。聚四氟乙烯套筒密封圓錐旋塞閥可用于基于硝酸的介質；對于基于醋酸的介質，可以選擇Crl8Nil2M02Ti四氟乙烯套筒密封圓錐形旋塞閥不銹鋼鑲嵌。
⑤ In the large-scale chemical industry, it is necessary to quickly open or close pipelines and equipment containing corrosive media. The PTFE sleeve sealed conical plug valve can be used for nitric acid based media; For acetic acid based media, Crl8Nil2M02Ti tetrafluoroethylene sleeve sealed conical plug valve stainless steel inlay can be selected.
⑥在煤氣.天然氣.在暖通系統的管道中和設備上，公稱直徑不大于200nm，建議選擇填料式圓錐旋塞閥。
⑥ On pipelines and equipment in gas, natural gas, and HVAC systems, it is recommended to choose a packing type conical plug valve with a nominal diameter of no more than 200nm.
