Abstract
An anti-freeze water supply system and its dedicated electromagnetic valve for solar water heater features that a dedicated electromalgnetic valve on the insulating water tank is linked to its water supply pipeline and water discharge pipeline to prevent freeze. Its advantages include simple structure, high reliability and low cost.
Description
The invention belongs to water supply system, particularly a profit exempts to freeze solar water heater water supply system and special electromagnetic valve.
Existing solar water heater water supply system mainly by attemperater, thermal-collecting tube, upper and lower conduit road, overflow passage, the fire hose is first-class forms.Because its attemperater and upper and lower conduit road are straight-through, thereby, just be full of water in the upper and lower conduit road as long as in the water tank water is arranged.In the winter of cold district the upper and lower conduit road takes place easily like this and freeze, freezing upper and lower conduit road causes solar water heater normally not use.For avoiding the upper and lower conduit road to be damaged by frost, usually the insulation measure is taked on the upper and lower conduit road, or dual-purpose is incubated and accompanies hot measure, not only improved cost, and the upper and lower conduit road take up room very big, its installation become not only complexity but also be subjected to various condition restriction and poor reliability, freezing upper and lower conduit road is still of common occurrence, has brought inconvenience for vast solar water heater user.
The purpose of this invention is to provide that a kind of cost is low, simple in structure, reliable operation, easy to use, that can realize not freezing winter exempts to freeze solar water heater water supply system and special electromagnetic valve.
The present invention realizes like this, it comprises attemperater, thermal-collecting tube, upper and lower conduit road and overflow passage, on attemperater, be connected to a special electromagnetic valve that links to each other with the upper and lower conduit road, this opening of valves during water on to attemperater, this valve cut out when last water stopped, thereby but last water finishes just emptying upper and lower conduit road, anhydrously in the upper and lower conduit road can not freeze naturally.This opening of valves when water, the water in the attemperater enters the upper and lower conduit road by this valve, and this valve cut out when water finished, and emptying upper and lower conduit road had so both guaranteed the normal use of solar water heater again, had realized that again the solar water heater water supply system exempts to freeze.
The present invention is simple in structure, and reliable operation is easy to use, can save the installation and maintenance investment, and good freezing protection effect, can save the solar water heater mounting material significantly and be installed working time.Special electromagnetic valve of the present invention can be used for various solar water heater water supply systems and various solar thermal collector.
Fig. 1 is the structural representation of solar water heater water supply system of the present invention;
Fig. 2 is the structural representation of special electromagnetic valve of the present invention;
Fig. 3 is the A-A profile of Fig. 2.
Provide embodiments of the invention below in conjunction with accompanying drawing:
As shown in Figure 1: the present invention has 1, one group of thermal-collecting tube 13 of an attemperater, upper and lower conduit road 6 and overflow passage 14; On attemperater 1, be connected to a special electromagnetic valve 2 that links to each other with upper and lower conduit road 6, be connected to control circuit 4 on the said special electromagnetic valve 2; On the said overflow passage 14 blow-off tee 15 is housed; Be connected to water supply valve 11, hot water valve 7, cold valves 9 and tap 8 on the said upper and lower conduit road 6 and link to each other with tap water pipe line 10; Be connected to switch 5 and power supply 3 on the said control circuit 4; Said thermal-collecting tube 13 has sealing ring 12 with the connecting portion of attemperater 1.
As shown in Figure 2: said special electromagnetic valve 2 has a sleeve pipe 24 of being made by stainless steel tube that has the gas thread 26 that can be connected with attemperater 1; Be connected to the valve body of making by copper pipe or stainless steel tube 20 that has the mouth of a river 22 and gas thread 25 in the said sleeve pipe 24, be equipped with unshakable in one's determination 19 and valve seat 23 in the said valve body 20; Be wound with coil 17 on said unshakable in one's determination 19; Said coil 17 is linked to each other with control circuit 4 by the lead 18 that passes filler 27; The seal washer of being made by silicon rubber 16 is arranged on the said valve seat 23, spherical valve plug 21 moving up and down is housed on seal washer 16; The gas thread 25 of said valve body 20 is connected with upper and lower conduit road 6.
As shown in Figure 3: said sleeve pipe 24 and valve body 20 decentraction have lead 18 to pass in both gaps and the filler 27 that is formed by pressure injection nylon are arranged.
During use, on giving attemperater 1, close hot water valve 7 and cold valves 9 during water; Open water supply valve 11, can utilize water pressure to push the valve plug 21 of magnetic valve 2 open or connect power supply 3 and make coil 17 energisings by the switch 5 of control circuit 4, unshakable in one's determination 19 pick up valve plug 21 by magnetic force, and last water 22 enters attemperater 1 by valve seat 23, seal washer 16 through the mouth of a river; Explanation attemperater 1 has stored up full water when overflow passage 14 water outlets, should finish to go up water, close water supply valve 11 this moment, valve plug 21 is by making coil 17 outages on the seal washer 16 of gravity fall to the valve seat 23 or by switch 5 deenergizations 3,19 magnetic force unshakable in one's determination disappear, discharge valve plug 21, valve plug 21 separates attemperater 1 and upper and lower conduit road 6 by on the seal washer 16 of gravity fall to the valve seat 23; Open hot water valve 7 in cold season, make water in the upper and lower conduit road 6 by tap 8 emptyings, and anhydrously in the upper and lower conduit road 6 can not freeze naturally.When water, connect power supply 3 and make coil 17 energisings by the switch 5 of control circuit 4, unshakable in one's determination 19 lean on magnetic force that valve plug 21 is picked up, water in the attemperater 1 enters upper and lower conduit road 6 by the mouth of a river 22, seal washer 16 and valve seat 23, open hot water valve 7 and regulate tap 8 leaving water temperatures with cold valves 9 as required, when finishing, water closes cold valves 9, make coil 17 outages by switch 5 deenergizations 3,19 magnetic force unshakable in one's determination disappear, discharge valve plug 21, valve plug 21 separates attemperater 1 and upper and lower conduit road 6 by on the seal washer 16 of gravity fall to the valve seat 23; Open hot water valve 7 in cold season, make water in the upper and lower conduit road 6 by tap 8 emptyings, and anhydrously in the upper and lower conduit road 6 can not freeze naturally.So both guaranteed that solar water heater normally used, realized again that the solar water heater water supply system exempted to freeze.
Special electromagnetic valve of the present invention is series of products, can be used for various solar water heater water supply systems and various solar thermal collector.Can select the 10mm-25mm special electromagnetic valve for use for general household solar heat hydrophone.Can select special electromagnetic valve for unit for use with solar thermal collector greater than 25mm.
