As shown in fig. 14, the steady flow control system composed of the adjustable steady flow valve includes a steady flow valve 100, a turbine 200, a flow sensor 300 and a control center 400, wherein the turbine 200 is disposed in a valve body 1 of the steady flow valve 100, and the turbine 200 is disposed facing a water inlet 11 of the steady flow valve 100; the flow sensor 300 is arranged outside the valve body 1 of the flow stabilizing valve 100, and the flow sensor 300 is used for receiving information of the turbine 200 and converting the information into flow information; the control center 400 is electrically connected with the flow sensor 300 and the adjusting mechanism 7, the control center 400 is used for receiving the flow information of the flow sensor 300, and the control center 400 is further used for judging whether the flow range represented by the flow information is larger than or contains the stable flow of the flow stabilizing valve 100; if not, the control center 400 controls the adjusting mechanism 7 to move, so that the pressure-bearing disc 6 moves towards the water inlet 11 until the flow information is larger than or includes the stable flow of the flow stabilizing valve 100. Specifically, a stepping motor is electrically connected to the control center 400, and the stepping motor drives the pressure bearing disk 6 to move axially on the sliding sleeve 4.

The flow of the water inlet 11 of the flow stabilizing valve can be detected at any time through the turbine 200 and the flow sensor 300, and the stable flow of the flow stabilizing valve can be adjusted in real time according to the water flow condition through the control of the control center 400, so that the stable flow state is continuously maintained.

Assuming that the initial flow stabilizing point of the flow stabilizing valve is 6L/min, when the flow of the household water pipe of a user is 8L/min, the flow sensor 300 detects that the water flow is a stable signal, at the moment, the flow stabilizing valve only plays a role in stabilizing the flow, and the flow can be stabilized at 6L/min; and if the flow of the user home is stable and is less than the steady flow point of 6L/min, stabilizing the flow of the flow stabilizing valve at the stable flow of the user home.

Assuming that the initial flow stabilizing point of the flow stabilizing valve is 6L/min, when the flow of the household water pipe of a user fluctuates between 8L/min and 10L/min, the flow stabilizing valve only plays a role of stabilizing the flow, and the flow is stabilized at the flow stabilizing point of 6L/min; when the flow of the household water pipe of a user fluctuates between 5L/min and 7L/min, the flow reaches the vicinity of the steady flow point of the flow stabilizing valve, the water valve only plays a role of steady flow, and the flow is stabilized at the steady flow point of 6L/min; when the flow of the household water pipe of a user fluctuates between 3L/min and 5L/min, the flow does not reach the steady flow point of the flow stabilizing valve, the fluctuation signal is identified by the control center 400, the control center 400 sends an electric signal to drive the stepping motor, the driving rod 71 and the pressure bearing disc 6 to rotate together, the size of the flow area of the water flow channel 41 is adjusted, the flow is stabilized at the minimum point 3L/min of the fluctuation range, and at the moment, the flow stabilizing valve plays a role in adjusting and stabilizing the flow.

For another example, in winter, when the temperature of the water heater is set to 45 ℃, and the temperature of the water heater cannot reach the set temperature of 45 ℃ after long-time combustion, the control center 400 sends an electric signal to drive the stepping motor, the driving rod 71 and the pressure-bearing disc 6 to rotate anticlockwise together, the distance between the pressure-bearing disc 6 and the outer support 3 is increased, and the flow channel stop block 5 is pushed to move towards the center, so that the flow area of the water flow channel 41 is reduced, the water flow is reduced, and the temperature of the water outlet of the water heater reaches the set value; at the moment, the flow stabilizing spring 8 extends, and the pretightening force of the flow stabilizing spring 8 is reduced, so that the small water pressure can reach the flow stabilizing value of the flow stabilizing valve, and the function of adjusting the working water pressure of the flow stabilizing valve is achieved.

For another example, in summer, the temperature of the water heater is set to 35 ℃, when the temperature of the water discharged after long-time combustion is higher than the set temperature of 35 ℃, the control center 400 sends an electric signal to drive the stepping motor, the driving rod 71 and the pressure-bearing disc 6 to rotate clockwise, the distance between the pressure-bearing disc 6 and the outer support 3 becomes smaller, the flow channel stop block 5 moves outwards under the action of water pressure, the flow area of the water flow channel 41 is enlarged, the water flow is enlarged, and the temperature of the water outlet of the water heater reaches a set value; at this time, the steady flow spring 8 is shortened, and the pretightening force of the steady flow spring 8 is increased, so that a large water pressure is needed to reach the steady flow value of the steady flow valve.

As shown in fig. 15, the adjustable flow stabilizing valve selectively has a plurality of flow stabilizing curves, i.e., a plurality of stable flows, by adjusting the position of the flow path block 5 and the degree of compression of the flow stabilizing spring 8.

When the adjustable flow stabilizing valve is used for a gas water heater, the requirement of a 13L water heater and the requirement of a 16L or 20L water heater with larger flow can be met, the research and development cost can be reduced, the research and development period can be shortened, and the universality is good; the adjustable flow stabilizing valve can be debugged according to the actual water pressure condition of a user home, so that the water heater works under the most suitable flow, and the adaptability is stronger; the adjustable flow stabilizing valve is not only an adjusting valve, but also a flow stabilizing valve, has two purposes, and can adjust the working water pressure of the flow stabilizing valve while adjusting the flow.
