Embodiment 1

[0032] like Figure 6 As shown, the working mode of single cycle heating includes the following steps:

[0033] 1. Judging whether a single loop has started, if the judgment result is yes, then jump to step 2; if the judgment result is no, then execute step 1 in a loop.

[0034] 2. The main controller of the water heater communicates with the intelligent control system and sends out the cut-off temperature data T.

[0035] 3. The electric shut-off valve is opened, the water pump starts to run, and the water heater heats the circulation pipeline.

[0036] 4. Determine whether the temperature detected by the temperature-sensing probe at the farthest water point reaches the cut-off temperature for 3 seconds or more. If the judgment result is yes, go to step 5; if the judgment result is no, execute step 4 in a loop.

[0037] 5. The electric shut-off valve is closed, the water pump stops, and the water heater stops working. Go to step 1.

Embodiment 2

[0039] like Figure 7 As shown, the working mode of all-day circulation heating includes the following steps:

[0040] 1. Judging whether the all-day cycle is enabled, if the judgment result is yes, then jump to step 2; if the judgment result is no, then execute step 1 in a loop.

[0041] 2. The main controller of the water heater communicates with the intelligent control system and sends out the cut-off temperature data T.

[0042] 3. The electric shut-off valve is opened, the water pump starts to run, and the water heater heats the circulation pipeline.

[0043] 4. Determine whether the temperature detected by the temperature-sensing probe at the farthest water point reaches the cut-off temperature for 3 seconds or more. If the judgment result is yes, go to step 5; if the judgment result is no, execute step 4 in a loop.

[0044] 5. The electric stop valve is closed, the water pump stops, and the water heater stops working.

[0045] 6. Judging whether the temperature of th...

Embodiment 3

[0047] like Figure 8 As shown, the appointment hydronic heating working method includes the following steps:

[0048]1. Judging whether the reservation cycle is enabled, if the judgment result is yes, then jump to step 2; if the judgment result is no, then execute step 1 in a loop.

[0049] 2. The main controller of the hot water judges whether it is currently within the reserved time period. If the judgment result is yes, then jump to step 3; if the judgment result is no, then execute step 2 in a loop.

[0050] 3. The main controller of the water heater communicates with the intelligent control system and sends out the cut-off temperature data T.

[0051] 4. The electric shut-off valve is opened, the water pump starts to run, and the water heater heats the circulation pipeline.

[0052] 5. The farthest water point temperature sensor detects whether the temperature reaches the cut-off temperature for 3 seconds or more. If the judgment result is yes, then jump to step 6; if ...

Abstract

The invention discloses an electric check valve and a zero cold water control system comprising the same. The electric check valve comprises a valve seat. A valve element is arranged on the valve seat. The electric check valve is characterized in that the valve seat belongs to a four-way valve and is provided with a hot water cavity and a cold water cavity; the valve element comprises a coil and an iron core mounted in the coil; the iron core is provided with a spring; one end of the spring is connected with a rubber head, and the other end of the rubber head is connected with a tray; the trayis provided with a diaphragm; and the hot water cavity and the cold water cavity communicate and disconnect through movement of the tray and the diaphragm. The electric check valve starts and stops to conduct cyclic heating by judging the temperature of a hot water end without setting the single-pass heating duration, and the problems of insufficient heating or excessive heating is avoided. Compared with an original check valve assembly, the electric check valve has the advantages that the size of the valve seat is greatly reduced, materials are saved, and the material cost is lower.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an electric stop valve and a zero cold water control system using the electric stop valve. Background technique [0002] When users use zero cold water series gas water heaters, they need to circulate and heat the water in the hot and cold water pipelines in the home. There are two methods: 1. Connect another return pipe to the cold water pipe and hot water pipe; 2. Use a check valve assembly to connect the cold and hot water pipes at the water point farthest from the water heater. The check valve assembly generally consists of two tees and a check valve core to allow water to flow from the hot water pipe to the cold water pipe. However, there are problems in the first method: the pipeline transformation of the user's family is relatively large, and the cost is relatively high. [0003] When the user installs a zero-cold water gas water heater under the condition of no ret...
