Detailed Description
The utility model is further described in connection with the following embodiments in order to make the technical means, the creation features, the achievement of the purpose and the effect of the utility model easy to understand.
Referring to fig. 1, a carrier for a pH electrode flow cell comprises a flow cell body 1 having a working cavity, the flow cell body having a generally cylindrical housing portion, the bottom of the housing portion having an arcuate shape which is folded to form an inlet structure, thereby forming an inlet 2 at the bottom of the flow cell body, the side of the flow cell body being provided with an outlet 6, a sealing cap 9 being mounted on the top of the flow cell body, the sealing cap 9 being mounted by a screw structure, as not specifically described, the product being 304 ss.
With continued reference to fig. 1, an inlet butt joint part 3 with a conical threaded hole is welded at the inlet of the bottom of the flow cell body, so that the flow cell has good water tightness when external devices such as an inlet connector and the like are butt-jointed and installed by the conical threaded hole, and the flow cell is more convenient and rapid to install. The top of awl screw hole is provided with the first reducing hole 4 that the internal diameter reduces gradually, the upper portion of first reducing hole is provided with the butt joint hole 5 the same with entry 2 internal diameter. The water flow can be gradually buffered at the inlet through the reducing holes. And an outlet butt joint part 7 with a conical threaded hole is welded at the outlet 6 of the flow cell body, and a second reducing hole 8 which is the same as the outlet is arranged at the tail end of the conical threaded hole of the outlet butt joint part. The outlet butt joint part 7 is an external outlet joint.
