Multi-purpose combined valve used for solar water heater

Abstract

The invention provides a multi-purpose combined valve used for a solar water heater. The multi-purpose combined valve comprises a valve body, a tap water inlet connector arranged on the valve body, a water taking connector arranged on the valve body, an overflow water connector connected with a water tank overflow pipe, and a falling and flowing water connector connected with a water tank water falling pipe. The water taking connector is communicated with the tap water inlet connector, the overflow water connector and the falling and flowing water connector through channels. The tap water inlet connector is communicated with the falling and flowing water connector. A water feeding regulating valve is arranged on the tap water inlet channel. A hot water regulating valve is arranged on the falling and flowing water channel. A cold water regulating valve is arranged on the water taking and water discharging channel. By means of the multi-purpose combined valve used for the solar water heater, the water heater can have the water falling type water taking function and the water ejecting type water taking function at the same time, the advantages of the two water taking manners are brought into play, and control pipelines of the solar water heater are easy and fast to use, compact in structure, easy to install and operate and low in manufacturing cost.

Description

technical field [0001] The invention relates to an upper water control valve for a solar water heater, in particular to a multipurpose combined valve for upper water for a solar water heater. Background technique [0002] Solar water heaters are usually installed on outdoor roofs and connected to indoor water valves through pipes. Low frequency, less water volume, and higher temperature hot water are the characteristics of solar water heaters. The water stored in the pipeline between the hot water storage tank and the water valve, based on the heat loss in the natural state, often needs to be drained before use, wasting a lot of water. [0003] The hot water use of household solar water heaters can be divided into: 1. bathing water, 2. washing water, and 3. kitchen water; according to the temperature adjustment method, it can also be divided into: a synchronous temperature adjustment, b post temperature adjustment. For hot water applications with synchronous temperature ad...

Problems solved by technology

The disadvantages of this multi-directional regulating valve are that one cannot provide a separate cold water channel, and cannot independently provide tap water; The water level in the medium, do you need to add water?

[0006] The solar water heaters in the prior art are equipped with water supply and water discharge control valves, whether they are split independent control valves or integrated multi-directional control valves, they cannot realize both falling water intake and top water intake at the same time. The respective advantages of the two water intake methods
