summary of the invention
The utility model is to solve above-mentioned deficiency, provide a kind of cold water that can make to enter solar thermal collector header to have the device of the process of an automatic preheating, make the cold water that enters solar thermal collector header just can improve temperature in preheating device the inside, reach the effect that the temperature difference of the temperature of water in the temperature of the water generating from preheating device and solar thermal collector header is dwindled, thereby solve the phenomenon of solar thermal collector vacuum tube explosion.
Utility model is achieved through the following technical solutions:
A kind of solar water heater feed pipe is from preheating device, described is by hot and cold water double-direction single-flow valve from preheating device, solar thermal collector header two parts are in conjunction with composition, described hot and cold water double-direction single-flow valve is provided with three interfaces, the one, cold water single current is to entering interface, the 2nd, hot water single current is to output interface, the 3rd, hot and cold water double fluid is to the interface of turnover, described double-direction single-flow valve inside is provided with a single current to cold water pipe, single current is exactly that cold water single current is to entering interface to the upper end of cold water pipe, single current is to align in parastate with the interface of hot and cold water double fluid to turnover to the lower end port of cold water pipe, described solar thermal collector header inside arranges a temperature isolation pipe, and the upper end of temperature isolation pipe is connected with the lower end port of single current to cold water pipe, at the bottom of the lower end of temperature isolation pipe extends to the case of solar thermal collector header.
Described cold water single current is connected with cold water upper hose to entering interface.
Described hot water single current is connected with hot water outlet pipe to output interface.
Described hot and cold water double fluid is connected with the interface on solar thermal collector header to the interface of turnover.
Described temperature isolation pipe is to be made by metal material, and its metal material is metallic copper and other Heat Conduction Material thereof.
The shape in the cross section of described temperature isolation pipe is circular or ellipse, square, rectangle, hexagonal any one.
The position of described temperature isolation pipe is arranged on the middle part of solar thermal collector header.
At the bottom of the lower end of described temperature isolation pipe and case, need retain certain spacing.
Described solar thermal collector header is provided with the interface being connected to inlet and outlet connectors with hot and cold water double fluid on hot and cold water double-direction single-flow valve.
When solar thermal collector is normally worked, in solar thermal collector header, the temperature of water is high temperature, when the cold water of cold water upper hose is by after preheating device, under the hot water effect of cold water in preheating device in solar thermal collector header, can progressively heat up, thereby dwindled with solar thermal collector header in the water temperature temperature difference, from then on, the cold water from preheating device the inside has been out warm water at the bottom of case.Because the water temperature in the water by from preheating device and solar thermal collector header differs, dwindle, thereby solved the phenomenon of solar thermal collector vacuum tube explosion.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
Solar water heater feed pipe is from preheating device, by hot and cold water double-direction single-flow valve 1, the combination of solar thermal collector header two parts, formed, on hot and cold water double-direction single-flow valve, 1 is provided with three interfaces, the one, cold water single current is to entering interface 3, the 2nd, hot water single current is to output interface 4, the 3rd, hot and cold water double fluid is to the interface 5 of turnover, double-direction single-flow valve 1 inside is provided with a single current to cold water pipe 6, single current to the upper end of cold water pipe 6, be exactly cold water single current to entering interface 3, single current is to align in parastate with the interface 5 of hot and cold water double fluid to turnover to the lower end port 7 of cold water pipe 6; Solar thermal collector header 2 inside arrange a temperature isolation pipe 8, and the upper end 9 of temperature isolation pipe 8 is connected with the lower end port 7 of single current to cold water pipe 6, and the lower end 10 of temperature isolation pipe 8 extends at the bottom of the case of solar thermal collector header 2 11.
Their correlation is:
