Globe Valve Seal Structure Improvement Experiment

Aug. 18, 2020

Globe valve has simple structure, the valve opened or truncated by the principle of rotation and the lifting, and to ensure that the valve sealing function. Since the special structure of movement principle, also contributed extremely negative consequences for the valve sealing force(both form vertical pressure, and friction between relative slip and the seal pair).
移动暴龙捕鱼 The sealing portion of the valve stem is moved to the valve tap. The purpose is to force the process, so that the valve on the sealing surface slip stay in a static state. This improvement can increase the seal life, due to increasing the seal between the valve flap and valve cover, such structure is more complex, cost is relatively low.
