VLB法兰碟阀
VLB flange disc valve
特点
由于本产品蝶阀采用的是偏心原理设计，使密封面的空间运轨迹达到理想化，密封面相互之间无摩擦、无干涉，加之密封材料选择得当，从而使蝶阀的密封性、耐磨性等得到了可靠的保证，具主要特点如下
1、开启力矩小，灵活方便，省力节能
2、偏心结构，使蝶板越关越紧，其密封性能可靠，达到无泄漏
Features
Because the butterfly valve of this product is designed by eccentric principle, the space movement track of the sealing surface is idealized, there is no friction and no interference between the sealing surface, and the sealing material is selected properly, so that the sealing and wear resistance of the butterfly valve are reliably guaranteed, and the main features are as follows
1. Small opening torque, flexible and convenient, labor saving and energy saving
2, eccentric structure, so that the butterfly plate closer and tighter, its sealing performance is reliable, to achieve no leakage
