A rotary valve with switching detection function and detection system

By setting a trigger component in the rotary valve to generate a level signal, the signal is only triggered after the valve core has switched to the correct position. Combined with the host computer and control system, this solves the misjudgment problem of existing rotary valve switching detection and achieves high-precision switching response time detection.

AI Technical Summary

Technical Problem

Existing rotary valve switching detection technology cannot accurately determine whether the valve core has truly been executed, and there is a risk of misjudgment. Furthermore, the accuracy of existing technology is easily affected by multiple factors, making it difficult to meet the requirements of high-precision control.

Method used

Design a rotary valve by setting a trigger component between the valve core and the limiting component. When the limiting component contacts the receiving part, a level trigger signal is generated to ensure that the electrical signal is triggered only after the valve core switching is completed. Combined with the host computer and control system, the switching response time can be accurately detected.

Benefits of technology

It enables direct and accurate detection of rotary valve switching, overcomes the problem of photoelectric sensor misjudgment, simplifies the position status recognition logic, and improves the detection accuracy of switching response time and system reliability.

Abstract

The present application relates to the technical field of micro valve, and discloses a rotary valve with switching detection function and a detection system, wherein the rotary valve directly links the mechanical switching action of a valve core with the generation of an electric signal.When the rotating assembly rotates and the limiting piece physically contacts the side wall of the accommodating portion, that is, the valve core is mechanically limited, the conductive assembly is triggered, and an electric level trigger signal is generated, so that it is determined that the rotary valve completes switching, and it is ensured that the electric level trigger signal can only be triggered when the valve core completes switching, direct and accurate detection of whether the valve core is truly switched in place is realized, and the switching state misjudgment problem of the photoelectric sensor is overcome.
