庞大的球阀家族，你认识几个？

　　How many members of the vast family of ball valves do you know?

　　你每天拧开自来水龙头、给汽车加油，可能没注意过一个关键部件 ——球阀。它不像闸阀那样 “笨重”，也不像截止阀那样 “迟缓”，只需旋转 90 度，就能快速控制介质的通断。今天我们就来认识一下“ 球阀家族 ”的各位成员，看看你都见过哪几种？1浮动球阀图：浮动球阀剖面图图：常见的浮动球阀

　　You may not have noticed a key component - the ball valve - when you turn on the tap and refuel your car every day. It is not as "bulky" as a gate valve, nor as "sluggish" as a globe valve. It only needs to be rotated 90 degrees to quickly control the on/off of the medium. Today, let's get to know the members of the "ball valve family" and see which ones you have seen before? 1 Floating Ball Valve Diagram: Floating Ball Valve Sectional Diagram: Common Floating Ball Valves

　　浮动球阀的球体是浮动的，在介质压力作用下，球体能产生一定的位移并紧压在出口端的密封面上，保证出口端密封。   浮动球阀的结构简单，密封性好，但球体承受工作介质的载荷全部传给了出口密封圈，因此要考虑密封圈材料能否经受得住球体介质的工作载荷，在受到较高压力冲击时，球体可能会发生偏移。这种结构，一般用于中低压球阀。浮动球阀适合一般工业使用。2固定球阀图：固定球阀剖面图图：常见的固定球阀

　　The ball of a floating ball valve is floating, and under the pressure of the medium, the ball can produce a certain displacement and press tightly against the sealing surface at the outlet end, ensuring the sealing of the outlet end. The structure of a floating ball valve is simple and has good sealing performance, but the ball bears all the load of the working medium transmitted to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. When subjected to high pressure impact, the ball may deviate. This structure is generally used for medium and low pressure ball valves. Floating ball valves are suitable for general industrial use. 2 Fixed ball valve diagram: Fixed ball valve sectional diagram: Common fixed ball valves

　　（左：电动固定球阀、右：手动固定球阀） 球阀的球体是固定的，受压后不产生移动。固定球球阀都带有浮动阀座，受介质压力后，阀座产生移动，使密封圈紧压在球体上，以保证密封。通常在与球体的上、下轴上装有轴承，操作扭距小，适用于高压和大口径的阀门。3V型球阀图：V型球阀剖面图图：常见的V型球阀

　　(Left: electrically fixed ball valve, right: manually fixed ball valve) The ball of the ball valve is fixed and does not move under pressure. Fixed ball valves are equipped with floating seats, which move when subjected to medium pressure, causing the sealing ring to press tightly against the ball to ensure sealing. Usually, bearings are installed on the upper and lower shafts of the sphere, with a small operating torque, suitable for high-pressure and large-diameter valves. 3V Ball Valve Diagram: V-shaped Ball Valve Sectional Diagram: Common V-shaped Ball Valves

　　V型球阀是一种高效的阀门，其设计独特，具有半球体阀芯一侧开有V形口的特点。   通过调节阀芯开度，可以有效地改变介质流通的截面积，实现精确的流量控制，同时还可以用于开关控制，实现管路的开启或关闭。   该阀门具有自清洗作用，能够在小开度范围内实现微小流量的调节，可调比大。适用于含纤维、细颗粒、料浆类介质。4多通球阀

　　A V-shaped ball valve is an efficient valve with a unique design, featuring a hemispherical valve core with a V-shaped opening on one side. By adjusting the opening of the valve core, the cross-sectional area of the medium flow can be effectively changed, achieving precise flow control. It can also be used for switch control to open or close the pipeline. This valve has a self-cleaning function and can adjust small flow rates within a small opening range, with a large adjustable ratio. Suitable for media containing fibers, fine particles, and slurries. 4-way ball valve

　　多通球阀是一种多功能阀门，主要用于管道系统中实现流体的分流、合流或切换控制。其核心特点是通过球体旋转动作实现流道切换，具有结构紧凑、流通能力大、密封性能优异等优点。5衬氟球阀图：常见的衬氟球阀

　　Multi port ball valve is a multifunctional valve mainly used in pipeline systems to achieve fluid diversion, merging or switching control. Its core feature is to achieve channel switching through the rotation of the sphere, which has the advantages of compact structure, high flow capacity, and excellent sealing performance. 5 Fluorine lined Ball Valve Diagram: Common Fluorine lined Ball Valves

　　(Left: electric fluorine lined ball valve, middle: electric three-way fluorine lined ball valve, right: fluorine lined ball valve)

　　衬氟球阀采用氟塑料作为内衬材料，具有更好的耐腐蚀性能，适用于各种强腐蚀性介质；具有极高的化学稳定性，适用于任何强腐蚀性化学介质。广泛使用于石油，化工，染化，农药，制酸制碱等行业，是防腐阀门最理想的选择。6其他球阀图：电动偏心半球阀偏心半球阀是一种比较新型的球阀类别，它有着自身结构所独有的一些优越性，如开关无摩擦，密封不易磨损，启闭力矩小。特别适用于钢铁业、铝业；有纤维、微小固体颗粒的纸浆，煤灰，石油气等行业。图：电动UPVC球阀   UPVC电动球阀采用双由令承插连接方式，安装拆卸方便。整体结构紧凑、体积小、重量轻。阀体卫生无毒，耐腐蚀性强。广泛用于纯水、生活用水、排水及污水管路、酸碱化学溶液系统。

　　Fluorine lined ball valves use fluoroplastic as the lining material, which has better corrosion resistance and is suitable for various highly corrosive media; Has extremely high chemical stability and is suitable for any highly corrosive chemical medium. Widely used in industries such as petroleum, chemical, dyeing, pesticide, acid and alkali production, it is the most ideal choice for anti-corrosion valves. 6 Other ball valve diagrams: Electric eccentric half ball valve Eccentric half ball valve is a relatively new type of ball valve, which has some unique advantages in its own structure, such as frictionless switch, less wear on seal, and small opening and closing torque. Especially suitable for the steel and aluminum industries; Industries such as pulp with fibers and small solid particles, coal ash, and petroleum gas. Image: Electric UPVC ball valve. The UPVC electric ball valve adopts a double lead socket connection method, which is easy to install and disassemble. The overall structure is compact, small in size, and lightweight. The valve body is hygienic, non-toxic, and highly corrosion-resistant. Widely used in pure water, domestic water, drainage and sewage pipelines, acid-base chemical solution systems.

　　全焊接球阀采用一体式设计，阀体和法兰通过焊接连接，无需额外的密封结构，有效防止泄漏问题。可承受高温、高压环境，保持阀体的稳定性和密封性。全焊接球阀的特殊结构和优势使其成为在苛刻工业环境中的理想选择。图：旋球阀旋球阀的结构类似于球阀，但其关键部分是一个球形截面，因此也被称为球形旋转阀。旋球阀主要由阀门体、旋转筒、旋转轴、连接杆等部件组成。阀体通常呈球形，由一个旋转的球体和两个固定的阀座组成。当球体旋转时，阀座会随之移动，从而实现介质的通断控制。

　　The fully welded ball valve adopts an integrated design, with the valve body and flange connected by welding, without the need for additional sealing structures, effectively preventing leakage problems. Can withstand high temperature and high pressure environments, maintaining the stability and sealing of the valve body. The special structure and advantages of fully welded ball valves make them an ideal choice in harsh industrial environments. Image: The structure of a rotary ball valve is similar to a ball valve, but its key part is a spherical cross-section, so it is also known as a spherical rotary valve. The rotary ball valve is mainly composed of valve body, rotating cylinder, rotating shaft, connecting rod and other components. The valve body is usually spherical, consisting of a rotating sphere and two fixed valve seats. When the sphere rotates, the valve seat will move accordingly, thereby achieving control of the on/off of the medium.
