Below in conjunction with accompanying drawing summary of the invention of the present utility model is described further:
With reference to Fig. 1, shown in Figure 2, a kind of pipeline emptying valve for solar water heater, valve body 1 connects a valve seat 20, valve body coil 4 has been intertwined and connected on its valve body 1, valve body 1 inner chamber is equipped with valve body piston 3, permanent magnet 7-1 is installed respectively on the valve body piston 3,7-2 and cushion rubber 8-1, one end of valve body 1 connects valve body jump ring 16 and solar water container connecting port 15, the other end connects valve seat 20, connect solar energy outlet conduit 14 on the valve seat 20, connect water injection valve 18 and outlet valve 19 on the solar energy outlet conduit 14 respectively, valve seat 20 connects air inlet valve body 2 by set screw 13, air inlet valve body 2 inner chamber bottoms are provided with float 9, cushion rubber 8-3 is installed on float 9 tops, air inlet valve body 2 inner chamber tops are provided with air inlet valve body piston 6, cushion rubber 8-2 is equipped with in air inlet valve body piston 6 lower ends, permanent magnet 7-3 is equipped with in the upper end, permanent magnet 7-3 is equipped with on top air inlet valve body jump ring 17, air inlet valve body jump ring 17 1 sides are installed airstrainer 10, suction valve body coil 5 has been intertwined and connected on air inlet valve body 2 excircles, suction valve body coil 5 is connected in series with valve body coil 4, rectifier 11 input ends are connected with civil power 220V electrical network, output terminal is connected lever type commutation automatic reset switch 12 1 ends, lever type commutation automatic reset switch 12 the other ends are connected on the valve body coil 4, and suction valve body coil 5 is connected lever type commutation automatic reset switch 12 the other ends.Wherein produce magnetic force after civil power 220V and suction valve body coil 5,4 conductings of valve body coil, commutation drives valve body coil 4 respectively to magnetic field boundary magnetic force, air inlet valve body piston 6 is done upper and lower motion in valve body by exchanging, and the effect of float 9 is not excessive by water.
At least be provided with two or more guiding ribs 21 on said valve body outside piston week.
Be provided with the annular flow water channel between the circle in outside piston in the said body cavity and the valve body.
Be provided with annular flat passage between the circle in float excircle in the said suction valve intracoelomic cavity and the air inlet valve body.
Be provided with annular flat passage between the circle in outside piston week in the said suction valve intracoelomic cavity and the air inlet valve body.
The utility model can be installed on any a solar energy easily.
Working principle is: when being the pipe evacuation state by the water supply state exchange, press the emptying end of lever type commutation automatic reset switch 12, the direct current (d.c.) that rectifier 11 produces flows through the electromagnetic coil 4 of polyphone, permanent magnet 7-1 polarity above in the induction field that electromagnetic coil 4 is produced and the valve body inner carrier 3 is opposite, opposite in the permanent magnet 7-2 polarity below piston 3 with top permanent magnet 7-1, but they are fixed in the piston 3, power between them is inoperative, but it is identical with the magnetic field polarity of bottom, magnetic field in the magnetic bottom, valve body piston 3 has enough big downward power offset top permanent magnet 7-1 the power of valve body jump ring 16 to be moved downward, the lower nozzle shutoff has been stopped water supply like this.Meanwhile, the top induction field that coil 5 on the air intake valve body 2 is produced is identical with permanent magnet 7-3 polarity in the air intake valve body piston 6, and air inlet valve body piston 6 has power upwards, and air inlet piston 6 moves upward, and run into air inlet jump ring 17, permanent magnet 7-3 holds air inlet jump ring 17 in the piston 6, even if moment, air inlet piston 6 can not fall down yet, air airstrainer 10 on air inlet valve body 2 like this, air inlet piston 6, float 9 peripheries enter pipeline, realize pipe evacuation.
When being converted to the water supply state by emptying state, press the water supply end of commutation automatic reset switch 12 when shouldering bar, the electric current that rectifier 11 produces turns to through lever type commutation automatic reset switch 12, permanent magnet 7-1 polarity above in the reverse induction magnetic field that is produced and the valve body inner carrier 3 is identical, but it is opposite with the permanent magnet 7-2 polarity below the piston 3, their induced force mutual superposition has the power that enough makes progress greatly, valve body piston 3 is moved upward, and run into valve body jump ring 16, permanent magnet 7-1 above in the valve body piston 3 holds valve body jump ring 16 firmly again and does not fall, meanwhile the induction field that produced of the electromagnetic coil 5 on the air inlet valve body 2 is opposite with permanent magnet 7-3 polarity in the air inlet piston 6, make air inlet piston 6 have enough power to offset air inlet piston 6 top permanent magnet 7-3 the suction of air inlet jump ring 17 is moved downward the shutoff suction port, because under the water supply state, valve body 1 inner chamber and air inlet valve body 2 inner chambers are negative pressure state, cause air inlet piston 6 to have bigger power to make the tightr of suction port shutoff, so just just in time avoided owing to the suction port bad sealing, and the same flow phenomenon of aqueous vapor that produces.
On the water-temperature water-level instrument of the automatic loading water under emptying state begins during water.Under the effect of last water hydraulic pressure, the impulse force of water will enter solar water heater water tank to valve body 1 inner carrier 3 jack-up, meanwhile, from air inlet valve pocket bottom, under floating function, float 9 moves upward and blocks the hole 22 of damming water through the valve body inboard aperture, cause water not excessive, and do not influence automatic loading water.
Learn that by top narration pipeline emptying valve for solar water heater provided by the utility model is owing to adopt electromagnetic coil, the current supply circuit of electromagnetic coil, air inlet valve body, permanent magnet are realized solar tube emptying.
