Description
Technical field
The utility model relates to a kind of valve that is used for the solar energy water heater pipe evacuation and anti-freezing.Particularly a kind of energy emptying solar water container shell is to the valve in inner bag and upper and lower conduit road.
Background technique
At present, solar water heater has obtained increasing use because it has characteristics such as considerable energy saving environmental protection.But in use especially when temperature is low, its yard piping when temperature is low, usually causes freezing of outdoor upper and lower conduit road stifled because water is arranged, and this not only causes the waste of water resources, especially has a strong impact on the normal use of solar water heater.For addressing the above problem, mainly contain following three kinds of methods: 1, adopt the pipeline tracing band; 2, adopt the electronics exhaust-valve; 3, put on the root superconducting heat pipe in the employing pipeline.But above-mentioned various way has in use also produced a lot of problems, and electric-heating belt is dangerous, fire hazardous and accident of human electric shock, and its power consumption is high, the life-span is short; Adopt the superconducting heat pipe technology, involve great expense in the prior art, effect is bad, and is subjected to the installation restriction to be difficult to apply.The gas introducing-type emptying that a patent No. is arranged in the prior art is ZL01237499.7 needs to adopt three quick opening valves realize pipe evacuation, though this purging method is reliable, but using process is very complicated, be difficult to grasp, and three quick opening valves are easily damaged parts, are unfavorable for promoting.Also has the ceramic seal emptying three-way valve that the patent No. is ZL01261313.4, though energy emptying solar energy upper and lower conduit road, but because its sealing position is beyond solar water container, so between inlet and outlet pipe lines between tank shell and the inner bag and the emptying three-way valve water is arranged still, when having arrived subzero, this section water is easy to be frozen in, and causes the current in the water tank not come out, and is difficult to realize thorough evacuation and anti-freezing.
Summary of the invention
The purpose of this utility model be exactly with defective at above-mentioned prior art, the thoroughly pipe line evacuation valve of evacuation and anti-freezing of a kind of simple in structure, safe and convenient to use, reliable performance is provided.
The utility model is achieved through the following technical solutions:
A kind of solar tube emptying antifreezing valve, the evacuation and anti-freezing that is used for solar water heater upper and lower conduit road, this valve is by valve body, be sealed into tracheae, electromagnet, connecting rod and pressure spring constitute, described valve body is a long tubular structure, valve body penetrates whole solar water container from top to bottom, have paddle hole on the sidewall of the part of described valve body in water tank, the described tracheae that is sealed into is a long tubular structure, be sealed into the internal diameter of the external diameter of tracheae less than valve body, being sealed into tracheae is arranged in the valve body, just be sealed in the tubular structure that tracheae is enclosed within valve body, the upper and lower end that is sealed into tracheae respectively has an opening, two openings communicate, in the position of valve body near water tank bottom, be provided with and be sealed into the tracheae sealed platform in the valve body, being sealed into the control of tracheae by electromagnet and connecting rod can move up and down in valve body, to close or the turnover water pipe of conducting valve, the conducting of fitted seal suction tude just can be carried out evacuation and anti-freezing to solar energy upper and lower conduit road again, because valve body is positioned in the water tank, the sealing platform that is used for sealing is positioned in the thermal insulation layer of water tank, so this valve energy emptying water tank liner is really realized the evacuation and anti-freezing of solar pipe to solar energy upper and lower conduit road.
When the water in the needs usefulness solar water container, can give above-mentioned electromagnet energising, make electromagnetic actuation, being sealed into tracheae by the connecting rod pulling moves up, make the interior water of water tank by the paddle hole on the valve sidewall, entering turnover water pipe and upper and lower conduit road by the sealing platform again flows into indoor: during water in needing drain-solar water heater upper and lower conduit road, cut off the power supply to electromagnet, electromagnet loses magnetism, also just lose connecting rod and be sealed into the active force of tracheae, being sealed into tracheae moves down under the effect of pressure spring, the turnover water pipe of valve is blocked at sealing platform place, stop the water in the water tank to flow into turnover water pipe and upper and lower conduit road, be sealed into the lower ending opening of tracheae and the turnover water pipe conducting at sealing platform place simultaneously, air is entered the upper end open that is sealed into tracheae and is entered the lower ending opening that is sealed into tracheae by the inlet hole on the valve body and enters turnover water pipe again, just enter the upper and lower conduit road of solar water heater, water in the upper and lower conduit road is flowed out by indoor water nozzle, realizes the thorough emptying of pipeline.
As improvement of the present utility model, above-mentioned pipe line evacuation valve also can change electromagnet on bent axle or cam, comes drive controlling with meshed transmission gear by motor by retarder.
As improvement of the present utility model, above-mentioned upper end open and the lower ending opening that is sealed into tracheae also can be located on the sidewall that is sealed into tracheae.
Use the utility model can avoid effectively that water tank liner to the pipe freezeup between the valve body is caused can't water because of temperature reduces, really realize the thorough evacuation and anti-freezing of solar pipe.
The utility model is described in further detail below in conjunction with accompanying drawing:
