An automatic water filling, emptying and pressurizing device and its use method

Abstract

Disclosed are an automatic water feed evacuating and pressurizing device and a using method thereof. The automatic water feed evacuating and pressurizing device comprises a water tank and a water pipe, and the upper surface of the water tank is provided with vent holes. The automatic water feed evacuating and pressurizing device is characterized in that an underneath type water temperature and level sensor is arranged in the water tank, a pressurizing pump is arranged at the joint of the bottom of the water tank and the water pipe, the U-shaped water pipe in the water tank is a siphoning pipeline, a normally-closed electromagnetic valve is arranged at an upper water port of the water pipe, a normally-opened electromagnetic valve is arranged at a lower water port of the water pipe, and the water temperature and level sensor, the normally-opened electromagnetic valve, the normally-closed electromagnetic valve and an evacuation control switch are connected with a control instrument respectively. The using method of the automatic water feed evacuating and pressurizing device includes steps of feeding water, evacuating fed water, discharging, evacuating the discharged water, and replenishing water. Automatic water feeding and discharging and automatic evacuating and water discharge pressurizing of a solar water heater can be controlled, evacuation and water supply are realized under the joint action of the siphoning pipeline and the pressurizing pump in the water tank, damage and cracking of pipelines in winter are avoided, and the automatic water feed evacuating and pressuring device is simple in structure, convenient to use and applicable to promotion and sales.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to an automatic water filling, emptying and pressurizing device and a use method thereof. Background technique [0002] Solar water heater is a very popular water heater, energy-saving and environmentally friendly, and easy to use. However, some functions and settings of solar water heaters have brought some troubles to people. For example, the automatic water supply and emptying of solar water heaters cannot be shared. There are conflicts in the function settings of water and emptying, so users can only choose one function, which is inconvenient to use; when using solar water heaters in some rural areas or residential buildings with a low drop, low hot water pressure and unstable water pressure often occur The situation brings a lot of inconvenience to users. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present inv...
