As shown in fig. 3, when the present invention is used, the hot water inlet 3 of the hot water three-way component is directly installed at the hot water outlet of the water heater through the internal thread, the cold water outlet 7 of the cold water four-way component is directly installed at the cold water inlet of the water heater through the internal thread, and the hot water outlet 4 of the hot water three-way component is connected with the hot water using terminal of the user through the hot water pipeline, such as: the hot water using terminals of a faucet, a water mixing valve, a shower faucet and the like are communicated. The cold water inlet 8 of the cold water four-way piece is communicated with a cold water supply pipeline through a pipeline. The pressure transfer port 5 of the hot water three-way piece is connected with the pressure transfer port 9 of the cold water four-way piece through a water pipe.
When a user opens the hot water using terminal, hot water flows out from a hot water outlet 4 of the hot water tee piece, the water pressure of the hot water outlet 4 is relieved, the water pressures of P3 and P2 are the same, the water pressure of P1 is the same as the tap water pressure, the water pressure of P1 is greater than the sum of the water pressure of P2 and the reverse pressure of a spring 13, a check rod 12 moves outwards towards P2, a cold water channel opening 19 is opened, cold water passes through a cold water inlet 8, the check rod 12 and the cold water channel opening 19, cold water is supplied to a water heater through a cold water outlet 7, the water heater works and heats, and the cold water is heated into hot water. Hot water passes through the hot water inlet 3, the one-way valve 6 and the hot water outlet 4 and finally reaches a hot water using terminal of a user.
When the user turns off the hot water using terminal, the hot water outlet 4 stops the water flow, and finally the water pressure of the hot water outlet 4, the water pressure of the P3 end, the water pressure of the P2 end and the water pressure of the P1 end are all equal to the water pressure of the tap water. The water pressure at the inner and outer ends of the check rod 12 is balanced, and under the action of the reverse pressure of the spring 13, the check rod 12 moves rightwards, the cold water passage port 19 is closed, and the supply of cold water to the water heater is stopped.
The check rod 12 has a reverse cold water seepage special design, and the reverse cold water seepage design quantity is ensured not to influence the normal outlet temperature of hot water for a user. Through reverse cold water seepage, even if the water heater has water leakage, as long as a user closes the hot water using terminal, the water pressure of the hot water outlet 4, the water pressure of the P3 end, the water pressure of the P2 end and the water pressure of the P1 end are finally equal through reverse cold water seepage design, the water pressure of the two ends of the inner side and the outer side of the check rod 12 is guaranteed to be balanced, under the reverse pressure action of the spring 13, the check rod 12 moves to the right, the cold water inlet channel port 19 is closed, and cold water supply to the water heater is stopped.
The principle and the implementation process of the invention for realizing the automatic on-off control function of the water supply of the water heater are described above.
Function 2: the one-way non-return function of the safety valve of the water heater is achieved.
The one-way non-return function of the safety valve of the water heater mainly prevents hot water in the water tank of the water heater from flowing back to the cold water pipeline from the cold water inlet of the water heater after the tap water of a user is cut off. As shown in figure 3, when the tap water of a user stops, the one-way valve 6 is reversely closed, the hot water port of the water heater is not communicated with the atmosphere, the check rod 12 is also reversely closed under the action of the spring 13, the cold water port of the water heater is not communicated with the atmosphere, and the water cannot be absorbed due to the siphon effect, so that the water in the water tank of the water heater cannot be discharged from the hot water outlet or the cold water inlet of the water heater, and the problem of hot water backflow cannot be caused.
In addition, as long as the spring force of the reverse spring of the one-way valve 6 and the spring force of the reverse spring 13 of the check rod 12 are set to be larger than the gravity drop pressure of the water in the water tank of the water heater in a proper range, the hot water can also be ensured not to flow backwards.
Function 3: the safety pressure relief function of the safety valve of the water heater is achieved.
The internal pressure relief function of the safety valve: as shown in figure 3, when the pressure in the water tank of the water heater is increased during heating, and when the pressure is larger than the force of the reaction spring 13 of the check rod 12, the check rod 12 moves reversely to open the cold water channel 19 to release the pressure in the water tank of the water heater to the pressure relief pressure and then to the cold water inlet pipeline. In addition, the check rod 12 of the invention is specially designed for reverse cold water seepage, so that the water tank of the water heater, the hot water outlet end of the water heater, the check valve 6, the check rod 12, the cold water inlet 8 of the cold water four-way component 2 are always communicated with the cold water inlet pipeline, and the internal pressure of the water tank of the water heater can also be discharged into the cold water inlet pipeline through the path.
The external pressure relief function of the safety valve: as shown in fig. 3, when the internal pressure of the water tank of the water heater reaches the set value of the pressure relief spring (26), the internal pressure of the water tank of the water heater pushes the pressure relief valve rubber pad 23 to move outwards, and the pressure relief water inlet (22) is opened to communicate the water tank of the water heater with the pressure relief water outlet (34), so that the function of automatically relieving pressure to the outside is completed.
Function 4: the manual water discharging function of the safety valve of the water heater is achieved.
As shown in fig. 3: if the water in the water tank of the water heater needs to be discharged manually, the cold water main switch of a user's home is only needed to be closed, the hot water three-way component 1 is detached by a wrench, the hot water outlet end of the water heater is communicated with the atmosphere, the handle 32 of the cold water four-way component 2 is manually opened, the water in the water tank of the water heater can be communicated with the pressure relief water outlet 34, the water in the water tank of the water heater is discharged completely, the hot water three-way component 1 is re-installed and tightened after the water is discharged completely, and the handle 32 of the cold water four.
Example two:
as shown in fig. 4 to 6, compared with the first embodiment, the difference is that the second embodiment adopts the hot water loose joint three-way member 1 and the cold water loose joint four-way member 2, the upper ends of the hot water loose joint three-way member 1 and the cold water loose joint four-way member 2 are both provided with the movable hexagonal nuts 20, the fixed joints 21A and the fixed joints 21B are respectively arranged between the hexagonal nuts 20 and the shell, and the installation and connection with the hot and cold water of the water heater are more convenient, but the first embodiment does not have the above components. The hot water inlet 3 of the hot water three-way component 1 and the hot water outlet of the water heater in the first embodiment, the cold water outlet 7 of the cold water four-way component 2 and the cold water inlet of the water heater are fixedly connected through internal threads, the hot water inlet 3 of the hot water loose joint three-way component 1 and the hot water outlet of the water heater in the second embodiment, and the cold water outlet 7 of the cold water loose joint four-way component 2 and the cold water inlet of the water heater are fixedly connected through the hexagonal nut 20.
