進(jìn)口電動(dòng)V型球閥功能介紹 Function introduction
進(jìn)口電動(dòng)V型球閥(調(diào)節(jié)型,開(kāi)關(guān)型)采用硬密封、四氟密封,配用角行程電動(dòng)執(zhí)行機(jī)構(gòu)輸入(4-20mADC或1-5VDC 信號(hào)及單相電源即可控制運(yùn)轉(zhuǎn),實(shí)現(xiàn)對(duì)進(jìn)口電動(dòng)V型球閥2.jpg壓力、流量、溫度、液位等參數(shù)的開(kāi)關(guān)或調(diào)節(jié) retz The imported electric V-type ball valve (regulating type, switch type) adopts hard seal and tetrafluoro seal, and is equipped with angular stroke electric actuator input (4-20mADC or 1-5VDC signal and single-phase power supply to control the operation, so as to realize the switch or adjustment of pressure, flow, temperature, liquid level and other parameters
設(shè)計(jì)特色 Design features
1、采用帶有V型切口的球芯結(jié)構(gòu),當(dāng)閥在關(guān)閉時(shí),可以剪切介質(zhì)中纖維、微小顆粒,同時(shí)由于閥芯和閥座之間是無(wú)間隙回轉(zhuǎn),可自行擦拭球體及閥座上的積垢物,保持球體與閥座之間的良好密封 The ball core structure with V-notch is adopted. When the valve is closed, the fiber and small particles in the medium can be sheared. At the same time, because the valve core and valve seat rotate without clearance, the dirt on the ball and valve seat can be wiped by itself to maintain a good seal between the ball and valve seat
2、采用帶彈簧或板簧加載閥座結(jié)構(gòu),由于彈簧/板簧的彈性恢復(fù)力推動(dòng)閥座,可使球芯與閥座之間長(zhǎng)期具有良好的密封性能。同時(shí)由于閥座采用彈簧加載的活動(dòng)結(jié)構(gòu),可使閥座自動(dòng)校正,以達(dá)到與球芯的精密吻合 The valve seat structure is loaded with spring or leaf spring. Because the elastic restoring force of spring/leaf spring pushes the valve seat, it can make the ball core and valve seat have good sealing performance for a long time. At the same time, because the valve seat adopts a spring-loaded movable structure, the valve seat can be automatically adjusted to achieve the best fit with the ball core
3、具有出色的調(diào)節(jié)特性:V型球閥具有一個(gè)近似等百分比的固有流量特性及高達(dá)300:1的可調(diào)比。因此V型閥可以在廣幅的變化范圍內(nèi)提供精確的控制 It has excellent regulation characteristics: V-shaped ball valve has an approximate equal percentage of inherent flow characteristics and an adjustable ratio of up to 300:1. Therefore, V-shaped valve can provide precise control in a wide range of changes
4、流動(dòng)大容積:由于它的流線(xiàn)型外形以及滿(mǎn)直角回轉(zhuǎn)控制緣故,使容積的值特別高,流通能力特別大,流通阻力小,因此可以使用較小的更加經(jīng)濟(jì)實(shí)用的閥門(mén)尺寸 Maximum flow volume: due to its streamlined shape and full right-angle rotation control, the maximum volume is particularly high, the flow capacity is particularly large, and the flow resistance is small, so a smaller, more economical and practical valve size can be used
5、V型球閥采用雙軸承結(jié)構(gòu),機(jī)械穩(wěn)定性能高,啟動(dòng)扭矩小,保證了閥門(mén)具有極好的靈敏度和感應(yīng)速度 V-type ball valve adopts double-bearing structure, with high mechanical stability and small starting torque, which ensures that the valve has excellent sensitivity and sensing speed
6、可靠(安全)性:閥體為一個(gè)整體,堅(jiān)固耐用,操作不受管道壓力影響,并可避免閥體滲漏 Maximum reliability (safety): the valve body is integral, firm and durable, the operation is not affected by pipeline pressure, and can avoid valve body leakage
7、金屬閥座的優(yōu)越密封性:V型球閥采用可動(dòng)金屬閥座,自助補(bǔ)償功能,并具有優(yōu)越密封性能及超長(zhǎng)的使用壽命。在流向上,泄漏量≤10-6×額定流量系數(shù) Superior sealing performance of metal valve seat: V-shaped ball valve adopts movable metal valve seat, self-help compensation function, and has excellent sealing performance and long service life. In flow direction, leakage ≤ 10-6 × Rated flow coefficient
8、高超的剪切能力:V型球閥采有金屬硬密封結(jié)構(gòu),V型球閥芯及金屬閥座在回轉(zhuǎn)過(guò)程中,V型缺口與閥座產(chǎn)生一個(gè)強(qiáng)大的剪切力能切斷纖維等雜質(zhì),并具有自潔功能,避免閥門(mén)卡死現(xiàn)象發(fā)生 Ultra-strong shearing ability: V-shaped ball valve adopts metal hard sealing structure. During the rotation of V-shaped ball valve core and metal valve seat, V-shaped notch and valve seat produce a strong shearing force to cut off impurities such as fiber, and have self-cleaning function to avoid valve jamming
