1. a kind of fluid flow control device, including:

  • Main body, described main body includes extending through the centre bore of described main body along its longitudinal axis;

    At least one first passage, it has almost parallel channel side wall, extends to described master from the lateral wall of described main bodyThe medial wall of body;

    At least one second channel, it has almost parallel channel side wall, extends to institute from the described lateral wall of described main bodyState the described medial wall of main body, and intersect to form level with least one first passage described, wherein said flow of fluid controlDevice processed is configured so as to flow by the fluid of each passage at the described level of the area contraction leading to flow of fluid to be passed throughImpact is from the fluid of other passages one or more, and compels to flow through the fluid of intersecting channels simultaneously ordinatedly by instituteState level, fluid goes successively to first passage and second channel and fluid experienced the area expansion that fluid can pass through from wherein flowingExhibition, and intersect related area, the described area contraction dough-making powder that flow of fluid is passed through compared to first passage and second channelLong-pending extension result in the reduction of the pressure of the fluid by described body flow control apparatus that flows.
