Detailed Description
As shown in fig. 1 to 4, the circulating mixing valve 103 includes a static valve element 1, a dynamic valve element 2, a cold water passage 201, a hot water passage 202, and a mixed water passage 203. The static valve core 1 and the dynamic valve core 2 are oppositely arranged. The static valve core 1 is provided with a cold water through hole groove 4, a hot water through hole groove 5 and a mixed water through hole groove 6. By the pressing of the pressing cover 206 and the sealing of the sealing gasket 205, the cold water through hole groove 4 is tightly communicated with the cold water channel 201, the hot water through hole groove 5 is tightly communicated with the hot water channel 202, and the mixed water through hole groove 6 is tightly communicated with the mixed water channel 203. A valve 207 is installed on the mixed water passage 203. A blind hole groove 3 is formed in the center of a sealing surface 7 of the movable valve core, which is in contact with a sealing surface 8 of the static valve core. The manual operation mechanism 204 for controlling the position of the movable valve element 2 is connected thereto.
Referring to fig. 5, the manual operating mechanism 204 controls the moving valve element 2 to be placed at the middle mixing position and the cold side position of the horizontal position, and the cold water through hole groove 4, the hot water through hole groove 5 and the mixed water through hole groove 6 are not communicated with each other at the hot side position. When the manual operating mechanism 204 controls the movable valve core 2 to be arranged at the hot side position of the lifting position, the hot water through hole groove 5 and the mixed water through hole groove 6 are communicated through the blind hole groove 3. When the manual operating mechanism 204 controls the movable valve core 2 to be arranged at the cold side position of the lifting position, the cold water through hole groove 4 and the mixed water through hole groove 6 are communicated through the blind hole groove 3. When the manual operating mechanism 204 controls the movable valve core 2 to be arranged at the middle mixing position of the lifting position, the cold water through hole groove 4 and the hot water through hole groove 5 are respectively communicated with the mixed water through hole groove 6 through the blind hole groove 3, namely, the cold water through hole groove 4 is communicated with the hot water through hole groove 5.
As shown in fig. 6, the water flow automatic on-off control pump 101 → the water heater 100 → the hot water pipeline 106 → the filter 108 → the hot water triangular valve 102 → the circulating mixing valve 103 → the one-way thermostatic stop valve set 104 → the cold water triangular valve 105 → the cold water pipeline 107 are connected together to form a preheating circulating pipeline. During preheating, the valve 207 on the mixed water channel 203 needs to be closed, the movable valve core 2 is placed in the middle mixing position of the lifting position through the manual operation mechanism 204, and the remote control power supply 300 is started. The circulating water mixing valve 103 is combined with a one-way heating blocking function of a one-way temperature control stop valve set 104 (the patent technology with the publication number of CN208871106U can be adopted), so that the preheating circulation of a local pipeline between the water heater and a water using point is realized, and no blind area exists in the preheating process. After preheating is completed, the remote control power supply 300 is turned off, the valve 207 is opened, cold water (or a small amount of warm water) flows out from the mixed water passage 203 when the movable valve element 2 is placed at the cold side position of the lifting position by the manual operation mechanism 204, and hot water flows out from the mixed water passage 203 when the movable valve element 2 is placed at the hot side position of the lifting position by the manual operation mechanism 204. I.e., to achieve "instant hot on" or "instant cold on".
Fig. 7 shows a circuit schematic of an alarm system. Referring to fig. 7, since the thermal block valve 104 blocks hot water flow when heated, it is monitored by the flow switch 304 whether the thermal block valve 104 blocks hot water flow to the cold water line 107. When hot water is delivered to a water consumption point, the one-way temperature control stop valve set 104 is heated to block water flow, so that the flow switch 304 is switched off, the contactor KM 308 is powered off, and further the power motor 306 of the water pump 101 is controlled by the automatic water flow switch to be powered off and shut down. In addition, when the flow switch 304 is turned off, the contactor KM 308 loses power, so that the buzzer BU 310 is powered on to alarm to prompt a user that hot water reaches a water using point; the remote control power supply 300 is turned off, the buzzer BU 310 loses power and stops alarming, and a user uses hot water safely.
