Abstract

The invention relates to a water supply pipeline control device of a solar water heater. The water supply pipeline control device adopts a structure in which an electromagnetic valve is configured with a bypass check valve. Water in a hot water pipe is exhausted under the action of the atmospheric pressure by utilizing a potential energy and a vacuum condition, so that an icing phenomenon of the water supply pipe of the solar water heater in winter can be removed. Therefore, the solar water heater also can be used normally in winter in vast northern areas.

Description

A kind of watering pipeline control device of solar water heater

Technical field

The present invention relates to a kind of watering pipeline control device of solar water heater, particularly a kind of at the northern area that the solar water heater watering pipeline is frozen, substitute traditional solar water heater watering pipeline.

Background technology

Solar water heater is brief bathroom fittings efficient, energy-saving and environmental protection, but is aided with the use of the electric heater unit four seasons.But in the winter of cold, because the ice formation issues of its watering pipeline has restricted the normal use of solar water heater.

Occur the problem of freezing in the winter time for solving the solar water heater watering pipeline, propose that meter is a kind of to be suitable for the solar water heater watering pipeline that northern wide geographic area uses winter.

Summary of the invention

The watering pipeline control device that the purpose of this invention is to provide a kind of solar water heater.Make solar water heater still can be applicable to the wide geographic area in the north in the winter time.

For realizing described purpose, the technical solution used in the present invention is: close the water tank of solar water heater and discharge water in the upper hose pipeline, make upper hose be in the state of " normal empty ".During use, open the water tank of solar water heater, can be to the exhaust of upper hose pipeline, water-filling.

A kind of watering pipeline control device of solar water heater, it comprises magnetic valve, non-return valve, Cold-hot water valve, hot-water line, angle coupling and insulation material, wherein, magnetic valve is directly connected in the water tank of water heater; Non-return valve is close to the open circuit connection that magnetic valve carries out maximum potential; The upper end of hot-water line is connected the lower end of non-return valve; The lower end of hot-water line is connected with the hot water valve of bathing vessel.

Further, implement to connect by three-way connection between described magnetic valve, non-return valve, the hot-water line, perhaps described magnetic valve and non-return valve are overall structure, directly are connected with hot-water line.

Further, described non-return valve is normally close valve, is arranged on the maximum potential place of upper hose bypass.

Further, described hot-water line is higher than the delivery port of bathing vessel from the location point of registering one's residence in the outdoor inlet chamber.

Described Cold-hot water valve namely can be the one valve, can also be separate valves.Be arranged on another end of upper hose, can be directly installed on the bathing vessel such as washbowl, shower, bathtub.

Described hot-water line namely can be the plastic-aluminum pipe, can also be the PPR pipe.When mounted, its potential energy of registering one's residence a little should be higher than bathing vessel such as washbowl, shower, bathtub.

Described insulation material is wrapped in the outer wall of hot-water line, and described insulation material is hardhead sponge circular arc profile, wraps up in the plastic strip structure outward, is used for using the hot water thermal insulating of intermittent time section.

Characteristics of the present invention are: adopted magnetic valve to join the syndeton of bypass non-return valve, utilized potential energy and atmospheric pressure that the upper hose of solar water heater is carried out draining.

The name of sequence number is called among the figure: (1) water tank, (2) angle coupling, (3) overflow pipe, (4) magnetic valve, (5) non-return valve, (6) three-way connection, (7) hot-water line, (8) water supply valve, (9) cold valves, (10) hot water valve, (11) shower.

The specific embodiment

The present invention will be further described below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, solar water heater upper hose pipe controller comprises by water tank 1, angle coupling 2, overflow pipe 3, magnetic valve 4, non-return valve 5, three-way connection 6, hot-water line 7, water supply valve 8, cold valves 9, hot water valve 10, shower 11 and forming.

Magnetic valve 4 and non-return valve 5 can be the split structure, and magnetic valve 4, non-return valve 5 and hot-water line 7 are connected by three-way connection 6.Magnetic valve 4 is directly connected in the water tank 1 of water heater; Non-return valve 5 is close to the open circuit connection that magnetic valve 4 carries out maximum potential; The upper end of hot-water line 7 is connected the lower end of non-return valve 5; The lower end of hot-water line 7 is connected with the hot water valve 9 of shower 11.Shower 11 in the present embodiment can also be bathing vessel such as washbowl, shower, bathtub.Hot-water line 7 is higher than the delivery port of bathing vessel from the position of registering one's residence in the outdoor inlet chamber.

Magnetic valve 4 in the present embodiment and non-return valve 5 also can be the overall structures that links into an integrated entity, and directly are connected with the upper end of hot-water line 7, at this moment, do not need to use three-way connection 6 to connect.Magnetic valve 4 as shown in Figure 2 and non-return valve 5 are the unitary whole structure, and the side that this moment, hot-water line 7 was connected non-return valve 5 gets final product.Magnetic valve 4 as shown in Figure 3 and non-return valve 5 are the unitary whole structure, and hot-water line 7 was connected between magnetic valve 4 and the non-return valve 5 and got final product this moment.

In order to prevent that the water spill-over in the water tank 1 from going out, the upper end of water tank 1 has a spout hole.Overflow pipe 3 is connected with spout hole by angle coupling 2.

Generally, opens solenoid valve 4 can be closed magnetic valve 4 and get final product with water supply valve 8 water tank 1 retaining with water supply valve 8 after water holds completely simultaneously.

In the winter of cold, by said sequence water tank is held full water after.Open hot water valve the water in the pipeline is emitted through shower, can prevent that upper hose from the phenomenon of freezing taking place.Its operation principle is: after hot water valve is opened, open at potential energy non-return valve under the effect of vacuum, air enters hot-water line through non-return valve under the effect of atmospheric pressure, thus the water in the discharge line.What will cause concern here is: registering one's residence of hot-water line a little should be higher than the delivery port of shower, otherwise residual water will take place to freeze in the outdoor hot-water line.

In use, while opens solenoid valve 4 and hot water valve 10, hot water can flow out from water tank 1, and its water temperature can be regulated by the cold valves 9 of shower 11.
