Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a mixing integrated device for heating systems. Background Technology

[0002] In the current construction industry, centralized heating or individual heating (such as wall-hung boilers and underfloor heating) is becoming increasingly common. It is popular because it provides stable heating and good comfort. However, for a heating system, it is necessary to mix cold and hot water to achieve a suitable heating temperature. Because heating equipment such as wall-hung boilers heats up slowly, especially in the initial stage, the pressure on the hot water side is generally lower than the pressure on the cold water side (return water). Sometimes, the supply of mixed water is insufficient, which often leads to the dry burning of the circulating water pump and frequent shutdowns. Utility Model Content

[0003] The purpose of this utility model is to provide a mixing device for heating systems to solve the problem that the pressure on the hot water side of the heating system is generally lower than that on the cold water side, resulting in insufficient mixing water supply, which often leads to the dry burning of the circulating water pump and frequent shutdowns.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A mixing device for a heating system includes a four-way solenoid valve, a chamber, a partition, and a circulating pump. The chamber is divided into a cold water chamber and a hot water chamber by the partition. The cold water outlet and hot water outlet of the four-way solenoid valve are respectively connected to the inlets of the cold water chamber and the hot water chamber. The partition is provided with a compensation hole connecting the cold water chamber and the hot water chamber. The inlet of the circulating pump is connected to the outlet of the hot water chamber. The hot water inlet of the solenoid valve and the outlet of the cold water chamber are respectively connected to the outlet and inlet of an external heating device. The cold water inlet of the solenoid valve is connected to the outlet of the external heating system. The outlet of the circulating pump is connected to the inlet of the external heating system.

[0006] A further technical solution is that the external heating device is a wall-mounted boiler.

[0007] A further technical solution is that the external heating system is an underfloor heating system.

[0008] A further technical solution is that a pressure gauge is installed on the cold water tank and a temperature gauge is installed on the hot water tank.

[0009] A further technical solution is as follows: a pressure sensor is installed on the cold water tank, and a temperature sensor is installed on the hot water tank. Both the pressure sensor and the temperature sensor are coordinated and controlled by a PLC controller to operate the four-way solenoid valve.

[0010] A further technical solution is that an exhaust valve is connected to the hot water tank.

[0011] A further technical solution is that the chamber body has a T-shaped structure.

[0012] A further technical solution is that an insulation shell is provided outside the water mixing integrated device.

[0013] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0014] This utility model proposes a mixing device for a heating system. The device uses a four-way solenoid valve to perform the first mixing at the point where hot and cold water exchange. Then, the mixed water flows through the hot water chamber of the compartment and is pressurized by the circulation pump to supply the heating equipment for external heating. During this process, the pressure between the compensation hole on the partition and the cold and hot water chambers is used to compensate for the defect of insufficient mixing and avoid the problem of dry burning of the circulation pump due to insufficient mixing.

[0026] This implementation example Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a mixing device for a heating system is disclosed. The mixing device 11 includes a four-way solenoid valve 1, a chamber 2, a partition 3, and a circulating pump 4. The chamber 2 is divided into a cold water chamber 5 and a hot water chamber 6 by the partition.

The cold water inlet of the solenoid valve 1 is connected to the outlet of the external heating system. The outlet of the circulating pump 4 is connected to the inlet of the external heating system.

[0027] The working process of this utility model is as follows: The external heating device (such as a wall-mounted boiler) supplies heated hot water to the four-way solenoid valve 1, and the outlet of the heating system (underfloor heating) also supplies cold water to the four-way solenoid valve 1. The hot and cold water are mixed for the first time in the four-way solenoid valve 1, and then the mixed water is supplied to the hot water tank 6. After being pressurized by the circulation pump 4, it is supplied to the heating system to provide heat to the outside. After heat exchange with the outside, it flows back to the four-way solenoid valve 1 and enters the cold water tank 5. Finally, it enters the external heating device and is pressurized again. During this process, the pressure between the compensation hole 7 on the partition 3 and the cold water tank 5 and the hot water tank 6 is used to replenish the water in the cold water tank 5 into the hot water tank 6, making up for the defect of insufficient mixing and avoiding the problem of dry burning of the circulation pump due to insufficient mixing.

[0028] Preferably, the external heating device is a wall-mounted boiler.

[0029] Preferably, the external heating system is an underfloor heating system.

[0032] Based on the above embodiments, a pressure sensor is installed on the cold water tank 5 and a temperature sensor is installed on the hot water tank 6. Both the pressure sensor and the temperature sensor are coordinated and controlled by the PLC controller to operate the four-way solenoid valve 1.

[0033] Under the action of pressure and temperature sensors, the operation of the four-way solenoid valve 1 is coordinated and controlled by the PLC controller to control the opening degree of the four-way solenoid valve 1, thereby controlling the amount of mixed water.

[0034] Preferably, the hot water chamber 6 is connected to an exhaust valve 10.

[0035] The air vent valve 10 is used to ensure the internal and external pressure balance of the hot water chamber 6, as well as to remove excess internal gas and ensure the water storage capacity.
