In the practical application process, the multifunctional flow regulating valve is arranged on the water heater. For the water heater, the water heater generally comprises a water heater main body, wherein the water heater main body is provided with a total water inlet port and a total water outlet port, and is also provided with a heating mechanism and the multifunctional flow regulating valve; the water inlet pipe of the multifunctional flow regulating valve is connected with the total water inlet port, the first water outlet pipe of the multifunctional flow regulating valve is connected with the inlet of the heating mechanism, and the second water outlet pipe of the multifunctional flow regulating valve and the outlet of the heating mechanism are respectively connected with the total water outlet port. The main water inlet port is connected with a water supply pipe (such as a tap water pipe) in the user's home, and the main water outlet port is connected with a water terminal (such as a shower or a tap water) through the water pipe in the user's home.
In a specific use process, the water terminal is used for being opened to output hot water outwards, and at the moment, the heating mechanism is started to heat water flowing through.
In the normal heating process, the multifunctional flow regulating valve is at the first position, and at the moment, the first flow control component 22 regulates the first water outlet pipe 12 to be at the maximum opening degree so as to obtain the maximum water flow; at the same time, the second flow control member 23 is in a position to close the second water outlet pipe 13, i.e. the bypass flow path is in a blocked position.
In the normal water use process, the power of the heating mechanism is reduced due to the influence of external factors, and at this time, the flow of the first water outlet pipe 12 needs to be regulated. At this point, the multi-function regulator valve will change between a first position and a second position. The driving part 21 acts to drive the first flow control part 22 and the second flow control part 23 to act, and the first flow control part 22 correspondingly adjusts the opening degree of the first water outlet pipe 12 so as to reduce water flow and further realize that the water temperature output by the water heater is kept constant; and the second water outlet pipe 13 is not opened for the second flow control member 23. In this process, according to the difference between the water outlet temperature and the set temperature of the water heater, the driving part 21 drives the first flow control part 22 to move in the forward and backward directions, so as to dynamically adjust the water outlet temperature.
In the case that the outlet water temperature of the water heater is continuously higher, the water flow entering the heating mechanism needs to be further reduced, and meanwhile, the bypass water flow is started. At this time, the multifunctional flow regulating valve will change between the second position and the third position, the driving part 21 acts to drive the first flow control part 22 and the second flow control part 23 to act, the first flow control part 22 correspondingly reduces the opening of the first water outlet pipe 12 to reduce the water flow, and the second flow control part 23 correspondingly increases the opening of the second water outlet pipe 13 to increase the water flow. In this way, in the process that the multifunctional flow regulating valve is changed between the second position and the third position, the water flow proportion of the first water outlet pipe 12 and the second water outlet pipe 13 can be regulated and controlled, and then the bypass duty ratio is dynamically regulated, so that the water temperature output by the water heater is kept constant.
In addition, when the user normally uses the water heater, when the user uses water twice in a short time, the multifunctional flow regulating valve changes between the second position and the third position so as to reduce the flow rate of cold water flowing into the heating mechanism and the mixing proportion of hot water and cold water output by the heating mechanism, so that the lowest temperature of water flowing out of the water heater is improved, the highest temperature of water flowing out of the water heater is reduced, the requirement of constant-temperature water outlet of the water heater is further met, and the shower experience of the user is further improved.
In an embodiment of the present application, the following is a specific way for adjusting the opening of the first water outlet 122 with respect to the retainer ring 222.

The rotary shaft 221 may also move along its axis relative to the valve housing 1 during rotation of the rotary shaft 221 relative to the valve housing 1 by the drive member 21.
In this way, for the process of adjusting the opening of the first water outlet pipe 12 to control the water flow rate, the retainer ring 222 is disposed at the pipe orifice side of the first water outlet pipe 12, and the flow rate of the first water outlet pipe 12 is adjusted in a rotating manner. The retainer ring 222 adjusts the flow of the first water outlet pipe 12 in a rotating manner, so that the flow is adjusted more accurately, the requirement of gradual step-by-step adjustment is met, and the requirement of adjusting the water flow entering the heating mechanism under different working conditions of the water heater is met.

Specifically, in order to conveniently adjust the flow rate of the first water outlet pipe 12 by adopting a rotating manner, the retainer ring 222 adopts a sleeve structure, the retainer ring 222 is disposed on the rotating shaft 221 and rotates along with the rotating shaft, the communication port 2221 can relatively rotate relative to the pipe orifice of the first water outlet pipe 12, and in the rotating process, the overlapping area of the communication port 2221 and the pipe orifice of the first water outlet pipe 12 is changed, so that the flow rate of the first water outlet pipe 12 is dynamically adjusted.
In an embodiment, the outer surface of the side wall of the retainer ring 222 is further provided with a water flow path 2222 communicating with the communication port 2221, and the water flow path 2222 extends in a direction away from the communication port 2221 about the axis of the rotating shaft 221.
Specifically, in the adjusting process of the water flow of the first water outlet pipe 12, the water flow can be adjusted rapidly by adjusting the overlapping area of the communication port 2221 and the pipe orifice of the first water outlet pipe 12. After the communication port 2221 is staggered from the nozzle of the first water outlet pipe 12, the water flow path 2222 is kept in communication with the nozzle of the first water outlet pipe 12, so that more accurate water flow adjustment can be performed through the water flow path 2222.
In some embodiments, a first partition 121 is disposed in the first water outlet pipe 12, and a first water outlet 122 is disposed on the first partition 121, where the first water outlet 122 is used to communicate with the communication port 2221 and the water flow path 2222.
Specifically, in order to conveniently control the opening degree of the first water outlet pipe 12 to precisely adjust the water flow rate, a first water outlet 122 that is matched with the communication port 2221 and the water flow path 2222 is formed on the first partition plate 121. During the rotation process of the retainer ring 222 following the rotation shaft 221, the communication port 2221 and the water flow path 2222 can rotate relative to the first water outlet 122 and realize communication, so as to more accurately control the water outlet flow of the first water outlet pipe 12.
