(调节型)进口气动V型球阀的阀芯设计成带有特殊开关的V型缺口,具有精确的截流特性和控制功能,启闭件采用V型球缺结构,完进口气动V型球阀4.jpg全解决了阀腔易沉积介质的问题,由于阀芯和阀座之间是无间隙回转,所以具有很大的剪切力及自洁性能,尤其适用于含有纤维性或有微小固体颗粒的悬浊液及固态颗粒状的控制 retz品牌 The core of the (regulating) imported pneumatic V-shaped ball valve is designed as a V-shaped notch with a special switch, which has precise flow closure characteristics and control functions. The V-shaped ball gap structure is adopted for the opening and closing parts, which completely solves the problem that the valve chamber is easy to deposit media. Since the valve core and valve seat rotate without clearance, it has great shear force and self-cleaning performance, It is especially suitable for the control of suspensions and solid particles containing fiber or small solid particles

特点Characteristic

1.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进口气动V型球阀5.jpg围内提供精确的控制 Excellent regulation characteristics: V-ball valve has an approximate equal percentage of inherent flow characteristics and an adjustable ratio of up to 300:1. Therefore, the V-valve can provide accurate control within a wide range of changes

2.大流动容积:由于它的流线型外形以及满直角回转控制缘故,使容积的最大值特别高,流通能力特别大,流通阻力小 Large flow volume: due to its streamline 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    

3.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 Double bearing structure is adopted, with high mechanical stability and small starting torque, ensuring excellent sensitivity and induction speed of the valve

4.安全可靠性能: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 Safe and reliable performance: the valve body is a whole, solid and durable, the operation is not affected by the pipeline pressure, and the leakage of the valve body can be avoided

5.金属阀座的优越密封性: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: movable metal valve seat with self-help compensation function, excellent sealing performance and long service life. In flow direction, leakage ≤ 10-6 × Rated flow coefficient

6.超强的剪切能力: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 Super shearing capacity: It adopts a metal hard sealing structure. During the rotation of the V-shaped ball valve core and metal valve seat, the V-shaped notch and the valve seat generate a strong shearing force that can cut off impurities such as fibers. It also has a self-cleaning function to prevent the valve from being stuck
