Specifically, the multifunctional flow regulating valve is assembled by the valve housing 1 and the regulating module 2, wherein the valve housing 1 is provided with the water inlet pipe 11, the first water outlet pipe 12 and the second water outlet pipe 13, so that the valve housing 1 is in a three-way structure as a whole. When assembling, assemble drive part 21, first accuse flow part 22 and second accuse flow part 23 on valve casing 1, drive part 21 can drive first accuse flow part 22 and second accuse flow part 23 and move in valve casing 1 inside, and first accuse flow part 22 arranges in first outlet pipe 12 department, and the play of activity first accuse flow part 22 can be adjusted the play water flow of first outlet pipe 12. Likewise, the second flow control member 23 is disposed on the second water outlet pipe 13, and the second flow control member 23 can adjust the water outlet flow of the second water outlet pipe 13.

The multifunctional flow regulating valve is provided with a first position, a second position and a third position, wherein in the process that the multifunctional flow regulating valve sequentially operates from the first position, the second position and the third position, the driving part 21 is used for driving the first flow control part 22 to gradually reduce the flow of the first water outlet pipe 12, and in the process of reverse operation, the driving part 21 is used for driving the first flow control part 22 to gradually increase the flow of the first water outlet pipe 12;

In the process of running the multifunctional flow regulating valve from the second position to the third position, the driving part 21 is used for driving the second flow control part 23 to gradually increase the flow of the second water outlet pipe 13, and in the process of running in the reverse direction, the driving part 21 is used for driving the second flow control part 23 to gradually decrease the flow of the second water outlet pipe 13.

The multifunctional flow regulating valve has three specific positions, specifically: in the state that the multifunctional flow regulating valve is at the first position, the first flow control component 22 controls the first water outlet pipe 12 to be at the maximum opening degree, and the second flow control component 23 closes the second water outlet pipe 13; in the state that the multifunctional flow regulating valve is at the second position, the second flow control part 23 is in a critical state of switching the second water outlet pipe 13; in the state of the multifunctional flow regulating valve in the third position, the first flow control part 22 controls the first water outlet pipe 12 to be at the minimum opening degree, and the second flow control part 23 controls the second water outlet pipe 13 to be at the maximum opening degree.

In this embodiment, in the process of operating the multifunctional flow regulating valve from the first position to the second position, the second flow control member 23 closes the second water outlet pipe 13, and in the process of operating in the reverse direction, the second flow control member 23 is still in a state of closing the second water outlet pipe 13.

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 the water heater main body is also provided with a heating mechanism and further comprises 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 the second embodiment, as shown in fig. 2 to 11, a specific way for adjusting the opening of the first water outlet 122 with respect to the retainer ring 222 is as follows.

One end of the side wall of the retainer ring is provided with a communication port, and the communication port is arranged at the side of the first water outlet and is configured to adjust the opening of the first water outlet in the rotation process of the retainer ring.

Specifically, for the first flow control member 22, the rotary shaft 221 is connected to a driving member 21 outside the valve housing 1, so that the rotary shaft 221 is driven to rotate by the driving member 21. 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.

The retaining ring 222 is of a sleeve structure, a water flow channel is formed between the retaining ring 222 and the rotating shaft 221, and a communication port 2221 is formed in the side wall of the retaining ring 222; the water flowing in from the water inlet pipe 11 flows into the first water outlet pipe 12 sequentially through the water flow passage and the communication port 2221.

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.
