Intelligent power-saving constant-flow valve, constant-flow valve control system and control method

Abstract

An intelligent power-saving constant-flow valve comprises an outer cover, a damping outer shell, a damping component, a connecting pipeline, a damping impeller, a drive motor (with a rotating speed sensor arranged inside) and connecting columns. The damping outer shell is fixedly connected with the connecting pipeline through the connecting columns. The damping outer shell is of a cylindrical shell and is provided with a round side plate. A round side wall protrudes along the circumference of the round side plate and has a fixed thickness. A containing cavity is formed by the above structure of the damping outer shell and used for containing the damping component. The outer cover and the damping outer shell cooperate to form a sealed cavity structure.

Description

technical field [0001] The invention relates to an intelligent power-saving constant-current valve, which is suitable for different water use occasions, such as families, hotels, hospitals and apartments. Background technique [0002] Traditional constant flow valves are usually used to control the flow of liquid by changing the channel size, so as to ensure the constant flow of water flow. For example, Chinese patent application 201621369909.5 discloses a pressure limiting constant flow valve, including a valve body with a limit The pressure chamber, the water inlet and the water outlet, the pressure limiting chamber is connected to the water inlet and the water outlet respectively; the pressure limiting device and the guide cylinder are arranged in the pressure limiting chamber; the pressure limiting chamber is connected to the water inlet through the guide cylinder; the pressure limiting device moves in the guide cylinder , and at the same time seal and close the same sid...

AI Technical Summary

Problems solved by technology

[0005] To sum up, in the prior art, in order to stabilize the water flow, the cross-section of the water flow channel is usually controlled by an elastic recovery member. Since the elastic coefficient of the spring is fixed, when it is necessary to stabilize the water flow at a freely set When the value is lower, the above-mentioned technical solution cannot be realized, and the above-mentioned elastic member is arranged in the water flow channel, resulting in a complicated structure of the pipeline, a complicated flow field, and unstable water flow, which is not conducive to maintenance by maintenance personnel.

[0006] Especially when the water flow does not meet the required minimum water flow requirement, the above technical solution does not have the function of increasing the water flow
