Example 1
As shown in fig. 1 to 4, the present embodiment provides a booster valve 100 including: valve body 10, solenoid valve 20 and power generation module 30.
The two ends of the valve body 10 are respectively provided with a first pipeline 11 and a second pipeline 12, and a communication pipeline 13 which is communicated with the first pipeline 11 and the second pipeline 12 is arranged in the valve body 10.
A solenoid valve 20 is provided on the communication pipe 13 for opening and closing the communication pipe 13.
The power generation module 30 is disposed on the first pipeline 11 and near the liquid outlet 111 of the first pipeline, and the power generation module 30 can generate power under the action of the water flow in the first pipeline 11 and provide power for the electromagnetic valve 20.
Wherein, when the power generation module 30 does not provide power to the solenoid valve 20, the solenoid valve 20 opens the communication pipe 13; when the power generation module 30 supplies power to the solenoid valve 20, the solenoid valve 20 closes the communication line 13.
In this way, by providing the specific structure of the pressure increasing valve 100, that is, by the power generating module 30, power can be generated under the condition that water flows in the first pipeline 11, so that power can be provided for the electromagnetic valve 20, so as to control the electromagnetic valve 20 to close the communication pipeline 13, and ensure the pressure increasing effect of the liquid outlet 111 of the first pipeline; no power is generated in the case where there is no water flow in the first pipe 11, so that the electromagnetic valve 20 cannot be supplied with power to control the electromagnetic valve 20 to open the communication pipe 13 so that the first pipe 11 and the second pipe 12 communicate for cyclic warm-up. That is, in the state where the water flows in the first pipeline 11 are different, the power generation module 30 can automatically drive the solenoid valve 20 to control the opening and closing of the communication pipeline 13 through the circulation condition of the fluid, so that the pressure boost valve 100 can automatically adjust the opening and closing of the communication pipeline 13 according to the circulation condition of the fluid, ensure the tightness of the closing of the communication pipeline 13 when the water flows in the first pipeline 11 (when the fluid is discharged from the liquid outlet 111 of the first pipeline, the water flow is generated in the first pipeline 11), realize safe and reliable fluid control, and achieve the required pressure boost effect.
In the prior art, in order to control the opening and closing of the electromagnetic valve, an external power supply mode is generally directly adopted, but because the booster valve is far away from the water heater, an independent electric control is needed to be connected with household appliances of a user. The booster valve 1 of the present embodiment ingeniously uses the water flow passing through the liquid outlet 111 of the first pipeline to convert into electric energy to supply power to the booster valve 1, and controls the electromagnetic valve 20 to close the communication pipeline 13, so as to exactly meet the requirement of closing the valve passage (the communication pipeline 13) when the hot water in the first pipeline 11 is used. Thus, the booster valve 1 of the present embodiment does not require an external power source, and is simple in structure and convenient to install.
In this embodiment, as shown in fig. 1, the flow direction X of the fluid in the first pipeline 11 and the flow direction Y of the fluid in the second pipeline 12 are the flow direction X of the fluid in the first pipeline 11 from the liquid inlet 112 of the first pipeline to the liquid outlet 111 of the first pipeline, and similarly, the flow direction Y of the fluid in the second pipeline 12 is the flow direction Y of the fluid in the second pipeline from the liquid inlet 122 of the second pipeline to the liquid outlet 121 of the second pipeline.

Specifically, the fluid flows into the first pipeline 11 from the liquid inlet 112 of the first pipeline, and pushes the impeller 32 to rotate when flowing to the liquid outlet 111 of the first pipeline, so as to drive the rotor to rotate and cut the magnetic force lines of the electromagnetic coil 31 to generate current, and provide power for the electromagnetic valve 20.
The operation mechanism of the booster valve 100 is specifically as follows:
as shown in fig. 1, when the liquid outlet 111 of the first pipeline is in a closed state, no water flow is generated in the first pipeline 11, the impeller 32 does not rotate, the rotor is not driven to rotate so as to cut the magnetic force lines of the electromagnetic coil 31, the power generation module 30 does not provide power for the electromagnetic valve 20, and the electromagnetic valve 20 opens the communication pipeline 13 so as to communicate the first pipeline 11 with the second pipeline 12;
as shown in fig. 2, when the liquid outlet 111 of the first pipeline is in an open state, water flow is generated in the first pipeline 11, the impeller 32 rotates under the impact of the water flow in the first pipeline 11 to drive the rotor to rotate so as to cut the magnetic force lines of the electromagnetic coil 31, the power generation module 30 provides power for the electromagnetic valve 20, the electromagnetic valve 20 closes the communication pipeline 13 and cuts off the communication between the first pipeline 11 and the second pipeline 12.
In this way, in the state where the water flows in the first pipeline 11 are different, the impeller 32 of the power generation module 30 rotates or does not rotate accordingly, so that power is generated or not, that is, whether the power generation module 30 supplies power to the electromagnetic valve 20 is automatically driven by the circulation condition of the fluid in the first pipeline 11, and the opening and closing control of the communication pipeline 13 through the electromagnetic valve 20 is achieved.
In this embodiment, the power generation module 30 further includes a fixing rod 33 and a supporting frame 34, the fixing rod 33 is disposed through the impeller 32 along the axial direction of the impeller 32, and two ends of the fixing rod 33 along the axial direction are respectively fixed on the supporting frame 34. Thus, the impeller 32 is fixed in the first pipe 11 by providing the fixing rod 33 and the supporting frame 34.
Further, the support frame 34 includes a first supporting member 341 and a second supporting member 342 that are disposed at intervals along the axial direction of the impeller 32, through holes 343 that penetrate along the axial direction of the impeller 32 are formed in the first supporting member 341 and the second supporting member 342, the peripheries of the first supporting member 341 and the second supporting member 342 are fixed on the side wall of the first pipeline 11, the electromagnetic coil 31 is located between the first supporting member 341 and the second supporting member 342, and two ends of the fixing rod 33 are respectively fixed on the first supporting member 341 and the second supporting member 342. Thus, by providing the specific structure of the bracket 28, a better fixing effect can be achieved for the impeller 32.

As shown in fig. 5, embodiment 2 discloses a water heater 200, wherein the water heater 200 includes the booster valve 100 of embodiment 1, and a hot water pipe 210 and a cold water pipe 220 which are connected to the booster valve 100 and are disposed at both ends of the booster valve 100, and a fluid flowing direction M of the hot water pipe 210 and a fluid flowing direction N of the cold water pipe 220 are shown in fig. 5. The hot water line 210 is pressurized by the water pump 230. The structure of the pressure increasing valve 100 is shown in fig. 1 to 4.
The liquid inlet 112 of the first pipeline is communicated with the hot water pipeline 210, the liquid outlet 111 of the first pipeline is communicated with a hot water outlet of the user side, the liquid inlet 122 of the second pipeline is communicated with the cold water pipeline 220, and the liquid outlet 121 of the second pipeline is communicated with a cold water outlet of the user side.
When the liquid outlet 111 of the first pipeline is in a closed state, no water flow is generated in the first pipeline 11, the power generation module 30 does not provide power for the electromagnetic valve 20, and the electromagnetic valve 20 opens the communication pipeline 13 to enable the first pipeline 11 to be communicated with the second pipeline 12. The water pump 230 drives the water in the pipeline to flow from the first pipeline 11 to the second pipeline 12, so that the circulating preheating effect is realized.
When the liquid outlet 111 of the first pipeline is in an open state, water flow is generated in the first pipeline 11, the impeller 32 rotates under the impact of the water flow in the first pipeline 11 to drive the rotor to rotate so as to cut the magnetic force lines of the electromagnetic coil 31, the power generation module 30 provides power for the electromagnetic valve 20, the electromagnetic valve 20 closes the communication pipeline 13, and the communication between the first pipeline 11 and the second pipeline 12 is blocked. The loss of the pressurizing effect of the water pump 230 on the hot water pipeline 210 is avoided, and the water outlet pressure requirement of the water use end of a user is ensured.
In this embodiment, by communicating the first pipeline 11 provided with the power generation module 30 with the hot water pipeline 210 of the water heater 200, on one hand, when the liquid outlet 111 of the first pipeline is in a closed state, i.e. no fluid passes through the power generation module 30, the communicating pipeline 13 is in an open state, so that the hot water flowing into the booster valve 100 at the liquid inlet 112 of the first pipeline enters the second pipeline 12 through the communicating pipeline 13 and circulates in the booster system where the booster valve 100 is located, and the fluid circulation direction Z during circulation can be specifically shown in fig. 2, so as to realize preheating of the booster system, so that when the user opens the hot water pipeline 210 at the user end, the required hot water can directly flow out without waiting, thereby improving the use experience of the user. On the other hand, with this configuration, the open-close control of the communication pipe 13 is realized, so that the flow condition of the hot water between the first pipe 11 and the second pipe 12 is regulated to realize the pressure effect required when the hot water is discharged from the liquid outlet 111 of the first pipe.
Therefore, in this embodiment, the pressure increasing valve 100 can increase the water pressure of the water heater 200, increase the flow rate and steady flow of the hot water supply, so that the outflow pressure is always kept within the ideal range, avoid the problem of unstable or too low hot water supply pressure, and improve the use experience of the user to the greatest extent.
