进口电动V型球阀(调节型，开关型）它采用板簧加载的可动阀座结构，阀座与球体不会产生卡阻或脱离等问题，密封可靠，使用寿命长。V型球阀阀芯设计成带有特殊开关的V型缺口，流通能力大，压力损失小，并具有精准的截流特性和控制功能，流量特性为近似等百分比
retz The imported electric V-shaped ball valve (adjustment type, switch type) adopts a movable valve seat structure loaded with leaf springs, and the valve seat and ball will not have problems such as jamming or detachment, with reliable sealing and long service life. The V-shaped ball valve core is designed with a V-shaped notch with a special switch, which has high flow capacity, low pressure loss, and precise interception and control functions. The flow characteristic is approximately equal percentage
进口电动V型球阀功能介绍 Function introduction
进口电动V型球阀(调节型，开关型）采用硬密封、四氟密封，配用角行程电动执行机构输入（4-20mADC或1-5VDC 信号及单相电源即可控制运转，实现对进口电动V型球阀2.jpg压力、流量、温度、液位等参数的开关或调节 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
设计特色 Design features
1、采用带有V型切口的球芯结构，当阀在关闭时，可以剪切介质中纤维、微小颗粒，同时由于阀芯和阀座之间是无间隙回转，可自行擦拭球体及阀座上的积垢物，保持球体与阀座之间的良好密封 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、采用带弹簧或板簧加载阀座结构，由于弹簧/板簧的弹性恢复力推动阀座，可使球芯与阀座之间长期具有良好的密封性能。同时由于阀座采用弹簧加载的活动结构，可使阀座自动校正，以达到与球芯的精密吻合 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、具有出色的调节特性：V型球阀具有一个近似等百分比的固有流量特性及高达300：1的可调比。因此V型阀可以在广幅的变化范围内提供精确的控制 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、流动大容积：由于它的流线型外形以及满直角回转控制缘故，使容积的值特别高，流通能力特别大，流通阻力小，因此可以使用较小的更加经济实用的阀门尺寸 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型球阀采用双轴承结构，机械稳定性能高，启动扭矩小，保证了阀门具有极好的灵敏度和感应速度 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：阀体为一个整体，坚固耐用，操作不受管道压力影响，并可避免阀体渗漏 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、金属阀座的优越密封性：V型球阀采用可动金属阀座，自助补偿功能，并具有优越密封性能及超长的使用寿命。在流向上，泄漏量≤10-6×额定流量系数 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型球阀采有金属硬密封结构，V型球阀芯及金属阀座在回转过程中，V型缺口与阀座产生一个强大的剪切力能切断纤维等杂质，并具有自洁功能，避免阀门卡死现象发生 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
