Abstract
A structure for connecting fluid channel of fluid delivery system is disclosed. This connecting structure limits the length of the flow-guiding pipe extending into the delivery channel, to reduce particle contaminates and the probability of crack. The present pipe union connecting structure comprises a first pipe, a second pipe mounted to the first pipe, and an inner pipe extending from the first pipe into the second pipe with a certain extending length. The extending length of the inner pipe is less than the proportion of the minimum distance between the inner wall of the second pipe and the outlet of the inner pipe when standstill, to the tangent value of a certain angle &thgr;, which is the maximum inclined angle between the second pipe and the inner pipe.
