Abstract
The utility model discloses a movable aeration concentration and flow rate measuring pin which comprises a pinhead. The bottom end of the pinhead is provided with a movable joint. The movable aeration concentration and flow rate measuring pin has simple structure and is convenient to use. The problem that when a sensor measuring pin of the conventional aeration concentration and flow rate measuring pin is broken, the whole sensor needs to be replaced is solved. The cost is saved. The movable aeration concentration and flow rate measuring pin is more convenient to measure.
Description
Technical field
The utility model relates to the field of aeration concentrater fluid-velocity survey, specifically is movable aeration concentrater flow velocity chaining pin.
Background technology
Aeration concentrater flow velocity chaining pin sensor is a kind of aeration concentrater flow rate measuring device, be mainly used in the mensuration of the aeration concentrater and the flow velocity of high-velocity flow, the measuring staff of sensor is provided with chaining pin, in measuring process, only need that the chaining pin of sensor is put into high-velocity flow and detect the bubble signal, import detected bubble signal into the data analysis terminal by sensor then, the bubble signal that collects is carried out data processing and analysis, complete aeration concentrater field, velocity field can be measured, and bubble size and distribution probability thereof can be detected.Be applied to the research of high dam outlet structure escape works ventilation corrosion inhibitor test and the aerated flow characteristics of motion, model law and air mixing corrosion reducing mechanism.But the chaining pin of existing aeration concentrater flow velocity chaining pin sensor all is to be fixedly installed on the measuring staff, when chaining pin has damage in measurement, whole sensor promptly can't be used, and will cause the increase of measuring cost like this, and need debug sensor again, cause the complicacy of measurement.
The utility model content
Technical scheme to be solved in the utility model provides a kind of movable aeration concentrater flow velocity chaining pin, and the chaining pin that solves existing aeration concentrater flow velocity chaining pin sensor damages the increase of the measurement cost that causes and measures complicated problems.
The technical solution of the utility model is:
Movable aeration concentrater flow velocity chaining pin comprises syringe needle, and the bottom of syringe needle is provided with movable joint.
Described movable joint is for being provided with female fitting sleeve or having externally threaded joint.
The utility model is applied on the aeration concentrater flow velocity chaining pin sensor, movable chaining pin is movably installed on the side lever by flexibly connecting head, when chaining pin has damage in measuring, can chaining pin be disassembled by flexibly connecting head, change new chaining pin, need not whole sensor is all replaced, not only saved cost, and manipulate more convenient.
The utility model is simple in structure, and is easy to operate, and solved traditional aeration concentrater flow velocity chaining pin sensor chaining pin and damage and promptly need whole sensor is all replaced, and saved cost, and measured more convenient.
