Description
Technical field
The utility model relates to a kind of pipeline emptying valve for solar water heater.
Background technique
Solar water heater normally is installed on roof or the roof, be communicated with user's water pipe by pipeline, owing to have water all the time in the pipeline, and these water can not heated by heat collecting pipe, and therefore, the user when using hot water at every turn, must earlier these cold water in the pipeline be bled off, after the user used up hot water, the hot water that has in the pipeline can be cooled to cold water again, and its drawback is: 1, cause the waste to valuable water resources; 2, reduced the utilization ratio of hot water; 3, in the winter time, easily with frost crack pipe, influence the user and use.The method that solves above-mentioned drawback is a water not in the user uses hot water relief pipeline at every turn, and the technological scheme that realizes this method is a pipe laying exhaust-valve on solar water heater.Pipe line evacuation valve is varied, and wherein a kind of suction tude of pipe line evacuation valve preferably is contained in that water tank is inner to be connected with float, is furnished with direct current generator and reducing gear in use, by the sense of rotation of change direct current generator, makes valve opening or closes.The deficiency of this pipe line evacuation valve preferably is: 1, to be furnished with direct current generator and reducing gear, thus the complexity that structure is become; 2, owing between the inwall of the piston of pipe line evacuation valve and valve body seal ring is housed, the sealing circle is in use fragile because of repeated friction, in case damage, do not seal, water will be seeped in the motor room, causes the damage of direct current generator, so working life is short.
Summary of the invention
The purpose of this utility model provides a kind of pipeline emptying valve for solar water heater of simple in structure, long service life.
In order to realize above-mentioned purpose, the pipeline emptying valve for solar water heater that is provided, comprise valve body, the piston that has center hole is housed in the inner chamber of valve body, valve body is provided with water tank connecting port that is connected with the water tank of solar water heater and the pipeline mouth of pipe that is communicated with pipeline, its structural feature is that piston is provided with the side opening that is communicated with center hole, one end of piston is connected with the tracheae connecting tube, be connected with permanent magnet on the other end, permanent magnet is provided with the endoporus that is communicated with center hole, be positioned at valve body on that end of permanent magnet and be wound with electromagnetic coil, this electromagnetic coil is connected in the current supply circuit.
Above-mentioned current supply circuit comprises two branch roads in parallel, wherein is in series with first group of rectifier and purge button on a branch road, is in series with second group of rectifier on another branch road and supplies the water button.
In order to prevent that this pipe line evacuation valve from being emptying state for moving with the water state mistiming, be positioned at valve body on the end face of that end of electromagnetic coil and be connected with armature.
When mounted, be connected to tracheae on the tracheae connecting tube, tracheae is placed in the water tank of solar water heater, and be fixed in the inner chamber of this water tank with the iron wire that is wrapped on the overflow.
Pipeline emptying valve for solar water heater provided by the utility model, when being the pipe evacuation state by confession water state exchange, press purge button, the direct current (d.c.) of first group of rectifier generation flows through electromagnetic coil, the induction field that electromagnetic coil produced is identical with the magnetic field polarity that permanent magnet is produced, produce repulsion, promoting piston moves to water tank connecting port direction, with the shutoff of the pipeline mouth of pipe, the pipeline mouth of pipe is discharged through outlet valve with the water in the lower pipeline, air is through tracheae simultaneously, the tracheae connecting tube, piston rod cavity, the piston inner hole and the pipeline mouth of pipe enter pipeline, realize the emptying of pipeline.When being converted to by emptying state when using water state, press for the water button, the reverse dc of second group of rectifier generation flows through electromagnetic coil, the induction field that electromagnetic coil produced is opposite with the magnetic field polarity that permanent magnet is produced, produce suction, inhalation-activated piston moves to the inductor coil end, and piston leaves the pipeline mouth of pipe, makes for water pipeline and solar water heater water tank and forms path.
Learn by top narration, pipeline emptying valve for solar water heater provided by the utility model, owing to adopt electromagnetic coil, the current supply circuit of electromagnetic coil and the pipe evacuation that permanent magnet is realized solar water heater, direct current generator and reducing gear have been removed, thereby simplified the structure of pipe line evacuation valve, reduced cost.The piston portion of pipe line evacuation valve is sealed in the valve body fully, has stopped the infiltration phenomenon, has prolonged working life.Save float in the water tank, reduced the incidence rate of fault.
