Technical Problem

[0005]本实用新型提供一种高承载抗变形的大口径蝶阀，可以有效解决上述背景技术中提出的现有的大口径蝶阀的阀管与驱动结构之间缺少高承载抗变形结构，使用时会因输送流体的高压力、大流量及驱动结构启闭时产生的较大扭矩，导致连接部位受力集中而出现形变，进而引发动力传递失衡，造成阀门启闭卡顿、无法精准控制开度的情况的问题

Benefits of technology

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By using the limiting cylinder, reinforcing column, shock-absorbing pad and corner support plate, it can effectively disperse the concentrated stress caused by high fluid pressure, large flow rate and driving torque, avoid deformation or misalignment of the connection parts, ensure stable and smooth power transmission, enable the valve to accurately control the opening degree and open and close without jamming. In addition, it can also reduce the fatigue wear of bolts, bearings and other components in the connection parts, reduce the probability of component loosening and damage, extend the overall service life of the valve, reduce the frequency of downtime maintenance and operation and maintenance costs, and thus ensure the long-term stable operation of the entire fluid transportation system.
