AI Technical Summary

Technical Problem

When the pressure fluctuates, the flow rate of the branch pipes in the existing water supply pipeline diversion device becomes unstable, resulting in a sharp drop in flow rate during peak water usage periods or an excessive flow rate during off-peak periods, and may even cause leakage problems.

Method used

It adopts a water storage tank and a water level sensing and regulating mechanism to automatically adjust the water inflow based on changes in the water level in the storage tank. It uses gravity diversion to isolate the impact of pressure fluctuations in the main pipeline on the branch pipelines, and adjusts the valve core opening through an adjustable rigid connecting rod and float structure to maintain a stable water level in the storage tank.

Benefits of technology

It achieves stability in diversion under pressure fluctuations, avoiding a sharp drop in flow during peak water usage periods and excessive flow during off-peak periods, thus ensuring the stability and safety of water use.

Abstract

This utility model relates to the field of diversion device technology, and more particularly to a water supply pipeline diversion device, including a water storage tank. The upper end of the water storage tank is connected to a main water inlet pipe, and the lower end of the water storage tank is connected to multiple branch water outlet pipes, allowing water in the water storage tank to flow naturally into the branch water outlet pipes by gravity. The water storage tank is equipped with a water level sensing and regulating mechanism for automatically adjusting the water inlet volume according to changes in the water level in the water storage tank. The water level sensing and regulating mechanism is connected to the output end of the main water inlet pipe, realizing that when the water level is lower than a preset value, the water inlet volume is increased, and when the water level reaches the preset value, the water inlet volume is stopped. This utility model, by setting up a water storage tank, using the main water inlet pipe to introduce water and maintaining a stable water level in the water storage tank through the water level sensing and regulating mechanism, allows water to flow into each branch water outlet pipe by gravity, thereby isolating the influence of pressure fluctuations in the main water inlet pipe on the branch water outlet pipes.
