Description
Technical field
The utility model relates to defroster, particularly relates to a kind of automatic drainage freeze preventer for water heater down pipes.
Background technology
Downcomer due to solar water heater total some be placed in outdoor, in the winter of cold, water in downcomer can freeze, light then downcomer blocks up, winter can not re-use solar water heater, heavy then downcomer bursting by freezing, not only solar water heater cannot be used winter, and downcomer leaks and brings water resource waste and piping foundation problem when temperature gos up, for this reason, some family in the winter time downcomer freezes front by solar water container and ducted water emptying thereof, or the hot water tap opening solar water heater slowly drips, solar water heater in the winter time utilization ratio is too low, also some producer sells downcomer heating tape, downcomer wraps heating tape, electrified regulation dredging water-supply-pipe when icing, which adds financial cost.
And in order to make solar water appliance have antifreeze function, in prior art, generally adopting wireway in parallel on sewer pipe, wireway lower end is introduced indoor and is connect valve, and wireway upper end is connected to water-supply-pipe upper end by water check valve.Although the disposable financial cost of this scheme is not high, be mainly used for the installation of solar water heater initial stage, can be very difficult if install wireway operation in parallel additional in the later stage, the technical scheme also had is the gap utilizing solar water heater, but this can cause the problem of restriction exhaust, because, common domestic solar water heater belongs to non-pressure-bearing type water heater, water tank only stays a gap to hold concurrently exhaust outlet, if have foreign matters from being blocked gap or gap place sluggish in air circulation, when discharging water, water tank inner air can not be supplemented immediately, inside and outside water tank mineralization pressure difference and take out flat water tank.
Therefore, need to provide a kind of new solar water heater anti-freeze pipe device to solve the problems of the technologies described above.
Utility model content
The purpose of this utility model is to provide a kind of automatic drainage freeze preventer for water heater down pipes, in order to solve the defect of above-mentioned prior art.
In order to achieve the above object, technical scheme provided by the utility model is: a kind of automatic drainage freeze preventer for water heater down pipes, and it comprises valve and drive motors; Described valve comprises valve body and the spool of device in valve body, described body top is provided with water inlet, and body base is provided with delivery port, and valve body side is provided with air inlet, described spool is provided with the fluid hole that water inlet is communicated with delivery port, and spool is provided with through venthole vertical with fluid hole; Described drive motors is packed in valve body opposite side, the driving wheel that in the rotating shaft of drive motors, mounting strap movable valve plug rotates.
Further, it also comprises gauge tap, and described gauge tap is connected with drive motors by wire.
Adopt technique scheme, technique effect of the present utility model has: when winter temperature is lower need by downcomer water discharge time, by driven by motor valve core rotation, water inlet on valve body is communicated with the fluid hole on spool with delivery port, now, venthole on spool is not communicated with the air inlet of valve body, after downcomer draining a period of time, in order to prevent pressure in drainpipe lower than ambient pressure, the water in drainpipe is caused to be arranged unclean, by driven by motor valve core rotation, venthole on spool is communicated with the air inlet of valve body, now, water inlet on valve body is not communicated with the fluid hole on spool with delivery port, make the air pressure balance in downcomer, water in downcomer can emptying, solve the problem that downcomer bursting by freezing causes solar water heater to use.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, structural representation of the present utility model, it comprises valve 1 and drive motors 2; Valve 1 comprises valve body 11 and the spool 12 of device in valve body 11, valve body 11 top is provided with water inlet 3, delivery port 4 is provided with bottom valve body 11, valve body 11 side is provided with air inlet 5, spool 12 is provided with the fluid hole 6 that water inlet 3 is communicated with delivery port 4, and spool 12 is provided with through venthole 7 vertical with fluid hole 6; Drive motors 2 is packed in valve body 11 opposite side, the driving wheel 21 that in the rotating shaft of drive motors 2, mounting strap movable valve plug 12 rotates, drive motors 2 drives spool 12 to rotate by driving wheel 21, in order to increase the sealing of valve 1, can install sealing gasket between valve body 11 and spool 12.
Using method of the present utility model is: be arranged on by the utility model on the downcomer of solar water heater, venthole 7 on spool 12 is rotated to the position opposing with the air inlet 5 on valve body 11, when downcomer does not need draining, movable valve plug 12 is with to be rotated counterclockwise 90 degree of rotations by drive motors 2, venthole 7 on spool 12 is communicated with the air inlet 5 of valve body 11, now, water inlet 3 on valve body 11 is not communicated with the fluid hole 6 on spool 12 with delivery port 4, downcomer can not draining, when winter temperature is lower need by downcomer water discharge time, movable valve plug 12 is with to rotate by drive motors 2, water inlet 3 on valve body 11 is communicated with the fluid hole 6 on spool 12 with delivery port 4, now, venthole 7 on spool 12 is not communicated with the air inlet 5 of valve body 11, after downcomer draining a period of time, in order to prevent pressure in drainpipe lower than ambient pressure, the water in drainpipe is caused to be arranged unclean, 90 degree are rotated counterclockwise by driven by motor spool 12, venthole 7 on spool 12 is communicated with the air inlet 5 of valve body 11, now, water inlet 3 on valve body 11 is not communicated with the fluid hole 6 on spool 12 with delivery port 4, make the air pressure balance in downcomer, water in downcomer can emptying.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
