【Abstract】 Influential factors leading to losing efficacy of the three way valve are analyzed, and some remaking measures are employed, including ball valve shim made from X resin ,fluorubber O shaped seal circle in the slit between the valve body and the valve cover. Under working circumstances, the reformed three way valve not only produces more reliable seal condition, but also has a longer life, which promises a remarkable commercial profit.更多还原
