(1)旋塞阀流体直流通过，阻力小，启闭方便。.迅速。

(1) The plug valve has direct flow of fluid, low resistance, and convenient opening and closing Quickly.

在管道中，旋塞阀主要用于切断管道.升级和改变介质的流动方向。新疆阀门生产厂家说它很容易适应多通道结构，甚一个阀门可以得到两个。.三个.即使是四种不同的流道，也能简化管道系统的设计，减少阀门用量和设备中所需的一些连接件。

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 the number of valves and some connectors required in equipment.

(3)旋塞阀是历史上的一种早些时候被人们使用的阀门。因其结构简单，开合迅速(塞旋转1/4)Q圆圈可以完成开合动作)，操作方便，流体阻力小，今仍被广泛使用。主要用于低压、小直径、低介质温度。

(3) Plug valve is a type of valve that was used earlier in history. Due to its simple structure, quick opening and closing (plug rotates 1/4), Q circle can complete the opening and closing action, convenient operation, and low fluid resistance, it is still widely used today. Mainly used for low pressure, small diameter, and low medium temperature.

根据旋塞阀的结构特点和设计所能达到的功能，可按以下原则选择。

According to the structural characteristics and design capabilities of the plug valve, the following principles can be followed for selection.

①新疆阀门生产厂家说用来分配介质，改变介质的流动方向，其工作温度不超过300℃，公称压力PN≤1.6MPa.公称通径不超过3000mm，选择多通道旋塞阀。

① The valve manufacturer in Xinjiang said that it is used to distribute the medium and change the flow direction of the medium. Its working temperature does not exceed 300 ℃, and the nominal pressure PN is ≤ 1.6MPa. The nominal diameter does not exceed 3000mm. It is recommended to choose a multi-channel plug valve.

②牛奶.果汁.建议选择奥氏体不锈钢、紧定式圆锥形旋塞阀等食品企业和制药厂等设备和管道。

② Milk and fruit juice. It is recommended to choose equipment and pipelines such as austenitic stainless steel, tight set conical plug valves, etc. for food enterprises and pharmaceutical factories.

③油田开采.开采天然气田.管道输送支管.在精炼和清洁设备中，公称压力级不大于Class300.公称不超过300mm，使用油封圆锥旋塞阀。

③ Oil field extraction, natural gas field extraction, pipeline transportation branches. In 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乌鲁木齐阀门生产厂家说油田开采.天然气开采.管道输送支管.在精炼和清洁设备中，公称压力级不大于Class公称通径不超过9000mm.工作温度不超过3400℃，使用油封圆锥旋塞阀。

④ The valve manufacturer in Urumqi recommends using oil sealed conical plug valves for oil field extraction, natural gas extraction, pipeline transportation branch pipes, and refining and cleaning equipment. The nominal pressure level should not exceed Class and the nominal diameter should not exceed 9000mm. The working temperature should not exceed 3400 ℃.

⑤在大型化工行业，在含有腐蚀性介质的管道和设备中，需要快速打开或关闭。乌鲁木齐阀门生产厂家说聚四氟乙烯套筒密封圆锥旋塞阀可用于基于硝酸的介质；对于基于醋酸的介质，可以选择Crl8Nil2M02Ti四氟乙烯套筒密封圆锥形旋塞阀不锈钢镶嵌。

⑤ In the large-scale chemical industry, it is necessary to quickly open or close pipelines and equipment containing corrosive media. The valve manufacturer in Urumqi said that PTFE sleeve sealed conical plug valves can be used for nitric acid based media; For acetic acid based media, Crl8Nil2M02Ti PTFE sleeve sealed conical plug valve stainless steel inlay can be selected.

⑥在煤气.天然气.在暖通系统的管道中和设备上，公称直径不大于200nm，建议选择填料式圆锥旋塞阀。

⑥ For pipelines and equipment in gas, natural gas, HVAC systems, with a nominal diameter not exceeding 200nm, it is recommended to choose a packing type conical plug valve.
