Corrosion-resistant PVDF butterfly valve structure

Abstract

The utility model relates to a kind of corrosion-resistant PVDF butterfly valve structure, including valve body and the valve seat being set on valve body, valve stem is rotationally arranged on valve seat, valve stem is provided with the valve plate compatible with valve seat, adjusting assembly is provided on valve body, adjusting assembly is connected with valve stem, one-way locking assembly is provided on valve body, one-way locking assembly and adjusting assembly are mutually matched, the utility model, by the cooperation of one-way locking assembly and adjusting assembly, so that the valve plate is in the state of completely sealing valve seat, adjusting assembly not only cannot continue to drive valve plate to rotate, and can effectively prevent adjusting assembly to carry out reverse stroke action, avoid the valve plate position deviation caused by misoperation, ensure that butterfly valve can keep stable sealing performance under sealing state, effectively improve the reliability and safety of butterfly valve;Meanwhile, butterfly valve structure adopts PVDF material, has excellent corrosion resistance, can adapt to various severe corrosive environment.
