用途Application
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、zui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zui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。
