龐大的球閥家族，你認(rèn)識(shí)幾個(gè)？

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

　　你每天擰開自來(lái)水龍頭、給汽車加油，可能沒注意過(guò)一個(gè)關(guān)鍵部件 ——球閥。它不像閘閥那樣 “笨重”，也不像截止閥那樣 “遲緩”，只需旋轉(zhuǎn) 90 度，就能快速控制介質(zhì)的通斷。今天我們就來(lái)認(rèn)識(shí)一下“ 球閥家族 ”的各位成員，看看你都見過(guò)哪幾種？1浮動(dòng)球閥圖：浮動(dòng)球閥剖面圖圖：常見的浮動(dòng)球閥

　　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

　　浮動(dòng)球閥的球體是浮動(dòng)的，在介質(zhì)壓力作用下，球體能產(chǎn)生一定的位移并緊壓在出口端的密封面上，保證出口端密封。   浮動(dòng)球閥的結(jié)構(gòu)簡(jiǎn)單，密封性好，但球體承受工作介質(zhì)的載荷全部傳給了出口密封圈，因此要考慮密封圈材料能否經(jīng)受得住球體介質(zhì)的工作載荷，在受到較高壓力沖擊時(shí)，球體可能會(huì)發(fā)生偏移。這種結(jié)構(gòu)，一般用于中低壓球閥。浮動(dòng)球閥適合一般工業(yè)使用。2固定球閥圖：固定球閥剖面圖圖：常見的固定球閥

　　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

　?。ㄗ螅弘妱?dòng)固定球閥、右：手動(dòng)固定球閥） 球閥的球體是固定的，受壓后不產(chǎn)生移動(dòng)。固定球球閥都帶有浮動(dòng)閥座，受介質(zhì)壓力后，閥座產(chǎn)生移動(dòng)，使密封圈緊壓在球體上，以保證密封。通常在與球體的上、下軸上裝有軸承，操作扭距小，適用于高壓和大口徑的閥門。3V型球閥圖：V型球閥剖面圖圖：常見的V型球閥

　　(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型球閥是一種高效的閥門，其設(shè)計(jì)獨(dú)特，具有半球體閥芯一側(cè)開有V形口的特點(diǎn)。   通過(guò)調(diào)節(jié)閥芯開度，可以有效地改變介質(zhì)流通的截面積，實(shí)現(xiàn)精確的流量控制，同時(shí)還可以用于開關(guān)控制，實(shí)現(xiàn)管路的開啟或關(guān)閉。   該閥門具有自清洗作用，能夠在小開度范圍內(nèi)實(shí)現(xiàn)微小流量的調(diào)節(jié)，可調(diào)比大。適用于含纖維、細(xì)顆粒、料漿類介質(zhì)。4多通球閥

　　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

　　多通球閥是一種多功能閥門，主要用于管道系統(tǒng)中實(shí)現(xiàn)流體的分流、合流或切換控制。其核心特點(diǎn)是通過(guò)球體旋轉(zhuǎn)動(dòng)作實(shí)現(xiàn)流道切換，具有結(jié)構(gòu)緊湊、流通能力大、密封性能優(yōu)異等優(yōu)點(diǎn)。5襯氟球閥圖：常見的襯氟球閥

　　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.

　　全焊接球閥采用一體式設(shè)計(jì)，閥體和法蘭通過(guò)焊接連接，無(wú)需額外的密封結(jié)構(gòu)，有效防止泄漏問題。可承受高溫、高壓環(huán)境，保持閥體的穩(wěn)定性和密封性。全焊接球閥的特殊結(jié)構(gòu)和優(yōu)勢(shì)使其成為在苛刻工業(yè)環(huán)境中的理想選擇。圖：旋球閥旋球閥的結(jié)構(gòu)類似于球閥，但其關(guān)鍵部分是一個(gè)球形截面，因此也被稱為球形旋轉(zhuǎn)閥。旋球閥主要由閥門體、旋轉(zhuǎn)筒、旋轉(zhuǎn)軸、連接桿等部件組成。閥體通常呈球形，由一個(gè)旋轉(zhuǎn)的球體和兩個(gè)固定的閥座組成。當(dāng)球體旋轉(zhuǎn)時(shí)，閥座會(huì)隨之移動(dòng)，從而實(shí)現(xiàn)介質(zhì)的通斷控制。

　　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.
