 气动V型调节球阀Pneumatic <wbr>V-Type <wbr>Adjusting <wbr>Ball <wbr>Valve

气动V型球阀是一种直角回转结构的高级控制阀,它与阀门定位器配套使用,可实现比例调节;与二位五通电磁阀及控制箱配套使用,可实现开关控制。V型球阀阀芯设计成带有特殊形状的V型缺口,具有精确的截流物性和控制功能,适用于各种控制场合,结构紧凑,体积小,可紧卧安装等优点。适用于气体、液体、固态颗粒状介质的控制。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。因此本产品可广泛用于石油、化工、造纸、化纤、电力、冶金、制药、环保等工业部门的自控系统。

Pneumatic V-ball valve is a right angle turn structure of the advanced control valve with positioner supporting the use of proportional control can be achieved; with two five-way solenoid valve and control box used to switch control. V-ball valve designed with a special shape of the V-notch, with precise closure properties and control functions for various control applications, compact structure, small size, tight horizontal installation, etc.. For gas, liquid, solid granular media control. As the valve core and valve seat is no gap between the rotation and therefore have a lot of shear force and self-cleaning performance, especially for fibrous or contain small solid particles in suspension and solid granular control. Therefore, this product can be widely used in petroleum, chemical industry, papermaking, chemical fiber, electric power, metallurgy, pharmaceutical, environmental protection and other industry-controlled system.


特点Feature

1、气动V型球阀由V型阀体与气动执行机构及其它附件组成。是一种直角回转结构的高级控制阀。V型球阀长期不需修理,使用寿命长,为您提供了真正的高效率进行控制工艺状况的一种阀门。 
2、具有出色的调节特性:V型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。 
3、最大流动容积: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,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。 
4、V型阀采用双轴承结构,机械稳定性高,启动扭矩小,保证了阀门具有极好的灵敏度和感应速度。 
5、最大可靠(安全)性:阀体为一个整体结构,坚固耐用,操作不受管道压力影响,并可避免阀体渗漏。 
6、金属阀座的优越密封性:V型阀采用可动金属阀座,具有的助补偿功能,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额定流量系数。 
7、超强的剪切能力:V型阀采有金属硬密封结构,V型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。 
8、气动V型球阀结构紧凑,小巧轻盈,安装方便,维护简便。 
9、气动执行机构采用活塞式气缸及曲臂转换结构,输出力矩大,体积精小。执行机构采用全密封防水设计防护等级高。气缸体采用进口镜面气缸,无油润滑,磨擦系数小、耐腐蚀、具有超强的耐用性及可靠性。所有传动轴承均采用边界自润滑轴承无油润滑,确保传动轴不摩损。

1, The pneumatic valve V-V-shaped body and by the pneumatic actuator, and other accessories. Is a rectangular structure of the advanced rotary control valve. V-ball valve repair without a long, long life, to provide you with the real state of efficiency of a process control valve. 
2, Excellent regulation characteristics: V-type valve has a similar inherent equal percentage flow characteristic and adjustable up to 300:1 ratio. Therefore, V-type valve in the wide range of rate changes to provide precise control. 
3, The maximum flow capacity: Because of its streamlined shape and the full right-angle turn control reasons, the maximum volume is particularly high, particularly through capacity, flow resistance, so you can use a smaller valve size is more economical and practical. 
4, V-valve dual-bearing structure, mechanical stability, high starting torque is small, to ensure the valve sensor with excellent sensitivity and speed. 
5, The maximum reliable (safe) sex: Body as a whole structure, durable, not subject to pipeline operating pressures, and to avoid valve leakage. 
6, Superior metal seat sealing: V-type valve is used movable metal valve seat, with the help compensation, and has superior sealing performance and long life. In the flow, the leakage rate 10 rated flow coefficient. 
7, Superior cutting ability: V-type valve with metal seal structure adopted, V-spool and metal seat in the process of rotation, V-notch with the valve seat to generate a strong shear force to cut off the fibers and other impurities , and has self-cleaning function to prevent the valve stuck phenomenon. 
8, The pneumatic valve V-compact, compact and lightweight, easy to install, easy to maintain. 
9, The use of pneumatic actuator cylinder piston and crank conversion structure, output torque, small size fine. Actuator design with fully sealed waterproof high degree of protection. Imported mirror cylinder block cylinder, oil-free lubrication, friction coefficient, corrosion-resistant, with superior durability and reliability. All drive bearings are self-lubricating bearings using the boundary-lubricating to ensure that no shaft wear.
