Flow regulating valve

By incorporating a sliding check valve and a temperature-sensing spring within the flow regulating valve, combined with a limiting step and valve core, automatic flow regulation based on changes in liquid pressure and temperature is achieved. This solves the problem of existing flow regulating valves being unable to adjust in real time, and improves the heating efficiency of the instant heating structure and the user experience.

AI Technical Summary

Technical Problem

The existing flow control valve cannot adjust the opening degree in real time according to changes in liquid pressure and temperature, making it difficult for the instant heating structure to heat the liquid to the set temperature, resulting in a poor user experience.

Method used

A flow regulating valve was designed. By incorporating a sliding check valve and a temperature-sensing spring within the valve body, combined with a limiting step and a valve core, the valve achieves automatic adjustment of the opening degree of the water passage and the water flow channel. The elastic coefficient of the temperature-sensing spring adjusts the movement of the valve stem according to temperature changes, and the check valve adjusts the flow rate according to changes in liquid pressure.

Benefits of technology

The flow regulating valve automatically adjusts the flow rate according to changes in liquid pressure and temperature, ensuring that the liquid in the instant heating device is heated to the set temperature, thus improving the user experience.
