Anti-scaling thermal conduction type flow controller

Abstract

The invention discloses an anti-scalingthermal conduction type flow controller. The anti-scaling thermal conduction type flow controller comprises a pipe body, a spiral blade, a controller fixing seat, a flow controller, a housing, a control circuit, an electrical interface, a control panel, a probe rod fixing seat, a threaded pipe, a fixing cover, a probe rod, two heating resistors, a temperaturesensor and an ultrasonic oscillator, flow passing through the interior of the pipe body are rotated through the spiral blade to impact the pipe wall and the top end of the probe rod, thus attachmentof scale deposit is reduced, when the heating resistors and the temperature sensor are placed in a fluid, the heating resistors are heated, the temperature sensor is used for sensing the medium temperature, under the condition that the heating power is constant, the temperature difference between the two heating resistors and the mass flow rate form a functional relationship, the control circuit can detect the fluid flow by detecting the temperature difference between the heating resistors and the temperature sensor, wires of the heating resistors and the temperature sensor penetrate through an inner cavity of the probe rod, and the wires of the heating resistors and the temperature sensor, the ultrasonic oscillator, and a through hole in the center of the fixing cover are electrically connected with the control circuit.

Description

technical field [0001] The invention relates to the technical field of flow controllers, in particular to an anti-fouling thermal conduction flow controller. Background technique [0002] Self-control flow control valve, also known as self-operated balance valve, flow regulating valve, flow controller, dynamic balance valve, flow balance valve, is an intuitive and simple flow adjustment control device, which is very common in production activities. The prolongation of the flow controller will scale or cover microorganisms, thereby weakening the conduction between the liquid and the probe, reducing the accuracy of the flow controller, and affecting the detection work. Most of the existing anti-scaling thermal conductivity flow controllers have simple structures and do not have an effective anti-scaling effect. After a long time of use, scaling will inevitably occur on the probe, thereby reducing the accuracy of detection. Contents of the invention [0003] The object of th...
