The new method of stainless steel butterfly interference of pneumatic valve

stainless steel butterfly pneumatic valve, as a kind of used to realize on-off and flow control of pipeline system for new type of pneumatic valve products, has been in the petroleum, chemical industry, metallurgy and widely used in many fields such as water and electricity. Triple eccentric multi-level hard seal butterfly stainless steel pneumatic valve is one of the most widely used stainless steel butterfly pneumatic valve, three eccentricity is mainly refers to the axial eccentric H, radial eccentricity and eccentric Angle alpha F. The size of the pneumatic valve switch moment, sealed performance is good or bad, and the length of the life cycle in addition to the associated with the structure of triple eccentric, mainly depends on whether the disc sealing ring and pneumatic seat also involves the size of the amount of interference. And whether do involves the size of the interference quantity directly determined by the three eccentricity. Traditional three partial hardness of stainless steel butterfly pneumatic valve seal interference check is with the method of 3 d modeling, quantity is big, time-consuming, cumbersome and complex changes and increase the design difficulty, cycle and cost. Through CAD 2 d graphics and simple method to introduce a new kind of simple, and easy to understand, convenient and practical method of interference. Traditional three partial hardness of stainless steel butterfly pneumatic valve seal interference check is with the method of 3 d modeling, quantity is big, time-consuming, cumbersome and complex changes and increase the design difficulty, cycle and cost.
