See also Fig. 1, Fig. 2, Figure 10 and shown in Figure 11, the operation principle of the present utility model and the course of work are:
One. the working condition during water inlet
Open water inlet switch earlier, water enters → then enters depressor area 72 → process diffluence pass 73 shunting backs → enter valve port 323 → then by the 3rd Inlet and outlet water 77 → enter the again storage tank (seeing Figure 11) of second Inlet and outlet water 78 → inflow solar water heater from first Inlet and outlet water 71
Along with the water level of the solar water heater storage water tank (see figure 1) that rises at leisure, also slowly the rising of ball float 20 in the utility model housing 10, the rising of ball float 20 drives pull bar 33 and rises, when rising, pull bar 33 arrives desired location, spool 34 and valve port 323 closures (seeing Fig. 2 and Figure 10) stop the last water to solar water heater storage water tank.
From as seen last, because spool 34 adopts inner pressed to close with valve port 323, utilize the pressure of water feeding pressure to withstand pull bar 33, make spool 34 tighter with the closure of valve port 323.
Two. the working condition during water outlet
Close water inlet switch earlier, open effluent switch, water in the housing 10 flows out (see figure 1), the water of pull bar 33 bottoms and pressure flow out from rushing down pore 3131, make pull bar 33 bottoms not only anhydrous but also do not have pressure, the water of solar water heater storage water tank is pushed spool 34 (seeing Figure 10 and Fig. 2) open automatically under the pressure of deadweight, water just from solar water heater storage water tank come out → through second Inlet and outlet water 78 → again through the 3rd intaking out 77 → entering valve port 323 → by diffluence pass 73 → enter first Inlet and outlet water 71 → flow into the at last place (seeing Figure 11) of water outlet.
By the explanation of the foregoing description, the utility model also has the following advantages:
1. therefore the utility model connects very convenient owing to the Inlet and outlet water linkage section 11 by housing 10 sides is connected with the turnover water end (W.E.) of solar water heater storage water tank;
2. the utility model is owing to the shared same water inlet-outlet segment 311 of Inlet and outlet water, and therefore not only materials are economized and be easy for installation;
3. the utility model is because the mode that adopts the inner pressed of ball float pulling force to close on valve, thereby makes the high more valve closing of water feeding pressure tight more, closes with the buoyancy of ball float by pressure closes valve door, the hydraulic pressure pressure of water feeding pressure is low simultaneously;
4. therefore the utility model is closed automatically when the water of water tank is expired, and can be limit according to the water level needs owing to adopt the inside of ball float pulling force to close mode, regulates the height of ball float 20 and controls water level;
5. the utility model is not only easy to use, and can not bleed off the hot water in the solar water heater storage water tank in operation, therefore can keep heat energy preferably.
