AB - The machining quality of the sealing surface of a triple-eccentric butterfly valve is crucial to its sealing performance. Especially, the measuring of sealing surface size is the key to assessing the machining quality. Due to the special structure of the triple-eccentric butterfly valve, the sealing surface size of the triple-eccentric butterfly valve is difficult and inaccurate to measure in position, which makes it difficult to ensure the machining quality of the triple-eccentric butterfly valve sealing surface. This will affect the sealing performance of the triple-eccentric butterfly valve and result in poor bidirectional sealing, non-interchangeability, and lower machining productivity of the bodies and discs. Based on the above problems, this paper proposes a new measuring method for sealing surface size, i.e., an in-position measuring method of point-replacing surface. The reliability of the method is analyzed and proved from the level of the design principle of the triple-eccentric butterfly valve. Further, the tooling fixture and in-position measuring device of sealing surface size are designed and manufactured based on the measuring method of the point-replacing surface. Different from the existing assembling boring process, this paper designs and manufactures new boring tooling fixtures and develops an integrated process of measuring and machining. After the preliminary measuring and machining test, the reproducibility of the results was good, and parts interchangeability and bidirectional sealing could be realized. And the application of this machining process significantly shortened the machining time and increased the machining efficiency by 25%.
