Description
Technical field
The present invention relates to a kind of solar water heater auxiliary equipment, particularly relate to a kind of solar water heater automatic freezing-protective device.
Background technology
Domestic solar water heater has interviewed since 30 years and is developed rapidly, and widely applies in city, rural households.But northern area cold in the winter time, solar water heater is then faced with the problem that pipeline freezes, and just can go out hot water, make the popularization of solar water heater receive resistance before using after also needing to release a part of cold water in addition.Existing frost valve cost is higher, complex structure is fragile, is difficult to promote, and cannot realize automatic freezing-protective and hot water plug and play.Therefore, can automatic freezing-protective and can the equipment of hot water plug and play in the urgent need to a kind of solar water heater on market.
Summary of the invention
Object of the present invention is just to provide to solve the problem a kind of can play automatic freezing-protective to solar water heater and can the solar water heater automatic freezing-protective device of hot water plug and play in the winter time.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes the exhaust-valve being built in water tank, the upper and lower conduit connecting water source and be arranged at the thermal switch between the outside upper and lower conduit of water tank.Described exhaust-valve is provided with exhaust-valve shell, electromagnet, upper silicon steel sheet, permanent magnetism, lower silicon steel sheet, pull bar, rubber cushion, piston storehouse, aqueous vapor storehouse, water inlet pipe and water outlet pipe and wire, piston storehouse is provided with piston storehouse exhaust outlet, exhaust-valve outer casing bottom is provided with exhaust-valve pore, airtight baffle is provided with between piston storehouse and aqueous vapor storehouse, silicon steel sheet is provided with bottom electromagnet, permanent magnetism is connected with the upper end of pull bar, pull bar urceolus upper end is provided with lower silicon steel sheet, pull bar lower end is connected with rubber cushion, the left port of water inlet pipe and water outlet pipe is communicated with water tank inner core by exhaust-valve shell, the upper port of water inlet pipe and water outlet pipe is vertically installed in immediately below rubber cushion, the lower port in aqueous vapor storehouse is connected with upper and lower conduit, permanent magnetism top is 1 centimetre to the distance of upper silicon steel sheet and permanent magnetism base to the distance sum of lower silicon steel sheet, rubber cushion top is 5 millimeters to the distance of pull bar urceolus lower port and rubber cushion base to the distance sum of water inlet pipe and water outlet pipe upper port, exhaust-valve shell is cylindrical structure, exhaust-valve outer casing bottom is provided with fixing card.
Further, described thermal switch and described electromagnet are connected in series.
Beneficial effect of the present invention is:
1, exhaust-valve shell adopts cylinder design, can enter water tank by straight cutting, solve the frozen problem of exhaust-valve, and convenient transformation.
2, the mutual magnetic force between exhaust-valve seal member employing magnet, as elastic force, eliminates spring strain problem, not fragile.
3, only need power instantaneously and get final product complete operation, a large amount of electric energy can be saved and environmental protection.
4, automatic-discharging can be realized, without the need to manual operation.
5, can realize hot water plug and play, any area all can use throughout the year.
6, structure is simple, and cost is low, is easy to promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
In figure: 1, electromagnet; 2, exhaust-valve shell; 3, wire; 4, upper silicon steel sheet; 5, piston storehouse; 6, permanent magnetism; 7, piston storehouse exhaust outlet; 8, pull bar urceolus; 9, water inlet pipe and water outlet pipe; 10, sealing ring; 11, fixing card; 12, exhaust-valve pore; 13, upper and lower conduit; 14, thermal switch; 15, aqueous vapor storehouse; 16, rubber cushion; 17, airtight baffle; 18, pull bar; 19, lower silicon steel sheet; 20, exhaust-valve; 21, tank outer wall; 22, heat-insulation layer; 23, water tank inner core.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1: when for 23 moisturizing of water tank inner core, artificial supply electromagnet 1 one moment forward current, make the magnetic of electromagnet 1 the latter half contrary with the magnetic of permanent magnetism 6 the first half, now, permanent magnetism 6 can move upward and to adsorb with electromagnet 1, due to the noncontact attraction produced between permanent magnetism 6 and upper silicon steel sheet 4, make rubber cushion 16 and pull bar urceolus 8 lower port closely sealed, current can enter aqueous vapor storehouse 15 through upper and lower conduit 13 by thermal switch 14, flow through left port by the upper port of water inlet pipe and water outlet pipe 9 again and enter water tank inner core 23, when the water temperature in upper and lower conduit 13 be down to 2 DEG C be about to freeze time, thermal switch 14 is connected, automatic supply electromagnet 1 one moment reversing the current, make the Magnetic Phase of the magnetic of electromagnet 1 the latter half and permanent magnetism 6 the first half same, now, permanent magnetism 6 can move downward and adsorb with lower silicon steel sheet 19, due to the noncontact attraction produced between permanent magnetism 6 and lower silicon steel sheet 19, make rubber cushion 16 closely sealed with the upper port of water inlet pipe and water outlet pipe 9, now, air enters aqueous vapor storehouse 15 by pull bar urceolus 8 by exhaust-valve pore 12 again by through piston storehouse exhaust outlet 7, now, upper and lower conduit 13 drains by upper and lower conduit 13 with the water in aqueous vapor storehouse 15, the water automatic-discharging in upper and lower conduit 13 can be realized like this, enter antifreeze state.When using water, mode of operation is identical with moisturizing, and artificial supply electromagnet 1 one moment forward current, hot water can flow through upper port by water inlet pipe and water outlet pipe 9 left port and enter aqueous vapor storehouse 15, more directly flows to user by upper and lower conduit 13, can realize hot water plug and play like this.So, moisturizing, to complete with water, emptying cycle.Therefore, the present invention is the object being reached automatic freezing-protective and hot water plug and play by emptying and control that is thermal switch.
