Title: Flow rate-stabilizing unit and analyzer where the same is installed
Inventor: NAKAMURA MORIZO
IPC: G01N1/10
Filed: 2002-02-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a flow rate-stabilizing unit that has a compact structure, and at the same time can constantly maintain a head pressure since the conventional flow rate-stabilizing unit utilizing the head pressure used for water analyzers requires head tanks, is large, and has a large occupation space.  <P>SOLUTION: The flow rate-stabilizing unit comprises: a sample water inlet for introducing sample water; a circulation section, which is a double tube for communicating with the sample water inlet, has a bottom in the lower portion of a gap section between the outer tube and the inner tube, and uses the gap section as a circulation path; a sample water outlet that is provided at the outer tube and a water overflow outlet that is located at a further higher position as compared with the outlet and forms the upper end of the inner tube; a waste liquid section with the inner wall gap section of the inner tube as an exhaust path; and the outer tube that is further higher than the water overflow outlet. Since the structure of the flow rate-stabilizing unit differs from that of the water overflow section in the conventional piping system, the sample water flows into the gap section of the inner pipe from the entire periphery from the water overflow section. Once the sample water flows into the gap section, it is further drawn to the drain side due to the flow and an effective exhaust effect can be obtained due to an aspirator effect, thus constantly maintaining a head pressure.  <P>COPYRIGHT: (C)2003,JPO
