Description

Technical Field

[0001] The invention relates to an air supply flow rate regulating system, in particular to a pipeline air supply flow rate regulating system. Background Art

[0002] Gas flow control device, namely gas flow control, is a flow measuring instrument for measuring mass flow in pipeline. When the measured fluid is in the condition of great changes in pressure, temperature and other parameters, if only the volume flow is measured, the change in fluid density will bring great measurement error. In volumetric and differential pressure flow meters, the density of the measured fluid may change by 30%, which will cause 30-40% error in flow. With the improvement of automation level, many production processes have put forward new requirements for flow measurement. Chemical reaction process is controlled by the quality (not volume) of raw materials, and the heating and cooling effects of steam and air flow are also proportional to the mass flow.

[0003] The flow controller is connected to the pipeline through the connecting ends at both ends. The pipeline is usually made of metal pipes with poor ductility. During installation, different heights of pipeline connections require installation bases of different heights to align the connection ends with the height of the pipeline. Therefore, in order to adjust the installation height of the flow controller, a pipeline gas flow control device is proposed in the prior art. However, it was found in the study that it still has defects: it can monitor the flow, but the adjustment of the gas flow is not flexible enough, resulting in a large limitation in the scope of application.

[0009] Preferably, a displacement slide rail is provided on the Z-axis lifting track, and a U-shaped movable bar is slidably installed in the slide rail, and evenly distributed transmission teeth are fixedly installed on the inner wall of one side of the U-shaped movable bar. The top of the lifting rod is fixedly connected to the bottom of the U-shaped movable bar, and the shrinkage cover is provided with an adjustment mechanism for driving the U-shaped movable bar to move.

[0010] Preferably, the adjustment mechanism includes a guide slide, a driving shaft, a linkage gear and an external handwheel.

[0011] Preferably, a positioning stopper is fixedly installed in the displacement slide rail, and the positioning stopper is located above the built-in cylinder.

[0012] Preferably, the height of the limiting sliding opening is greater than the height of the regulating blocking piston.

[0014] Preferably, the air inlet connector and the air outlet connector are both fixedly connected with mounting flanges.
