Description
Technical Field
[0001] The utility model relates to the technical field of waterway control of gas water heaters, and particularly relates to a waterway control device with a water replenishing function outlet valve. Background Art
[0002] At present, the waterway control device of a gas water heater is an important device for controlling heating water and domestic hot water in a household. In order to improve the energy-saving effect, most of them use the heating hot water to exchange heat with cold water through a heat exchange plate to obtain domestic hot water. During the operation of the entire heating water, it is basically in an overall closed pipeline system. The circulation and heating of the heating water are realized by a water pump. Then, the water in the heating system often becomes short during use, and there is a technical need for water replenishment. Most of the existing water replenishing valves are installed in the inlet valve, that is, direct cold water replenishment. This kind of cold water replenishment often causes the water temperature of the heating system to drop rapidly. How to achieve water replenishment for the heating system and have a smaller impact on the water temperature of the heating system is the object of research by those skilled in the art. Content of the Utility Model
[0003] The purpose of the utility model is to aim at the defects and deficiencies of the prior art, and provide a waterway control device with a water replenishing function outlet valve, which has a small impact on the water temperature of heating water replenishment and high-position water replenishment by a water pump.
[0004] In order to achieve the above purpose, the utility model provides a waterway control device with a water replenishing function outlet valve, which includes an inlet valve and an outlet valve. A heat exchange plate is installed between the inlet valve and the outlet valve. A water replenishing valve is installed on the valve body of the outlet valve. The valve body of the water replenishing valve and the valve body of the outlet valve are integrally formed. The valve body of the outlet valve respectively opens a water replenishing inlet pipe and a water replenishing outlet pipe on the side of the valve body of the water replenishing valve. A valve rod is installed in the valve body of the water replenishing valve, and the valve rod controls whether the water replenishing inlet pipe is communicated with the water replenishing outlet pipe. The water replenishing inlet pipe is communicated with the cold water inlet pipe of the inlet valve, and the water replenishing outlet pipe is communicated with the heating water outlet pipe of the outlet valve. This kind of waterway control device with a water replenishing function outlet valve installs a water replenishing valve on the valve body of the outlet valve. The water replenishing inlet pipe of the water replenishing valve is communicated with the cold water inlet pipe of the inlet valve. Since the cold water entering from the cold water inlet pipe has to flow through the heat exchange plate before entering the water replenishing valve, that is, the water entering the water replenishing valve is hot water that has been heat-exchanged. In this way, water replenishment avoids the problem of rapid temperature drop of the heating system caused by direct cold water replenishment. The water replenishing valve replenishes water to the heating system through the water replenishing outlet pipe communicated with the heating water outlet pipe of the outlet valve.
[0005] After the valve body of the outlet valve is drilled to obtain the water replenishing inlet pipe, the water replenishing inlet pipe is blocked by a plug in the first plugging pipe. After the valve body of the outlet valve is drilled to obtain the water replenishing outlet pipe, the water replenishing outlet pipe is blocked by a plug in the second plugging pipe. The structures of the first plugging pipe and the second plugging pipe solve the technical problems formed by the flow channels of the water replenishing inlet pipe and the water replenishing outlet pipe.
[0006] The described inlet valve includes a cold water inlet pipe and a heat exchange hot water outlet pipe. The cold water inlet pipe is respectively connected to a flow sensor and a cold water heat exchange plate connecting pipe through a water path; the heat exchange hot water outlet pipe is respectively connected to a water pump connecting pipe and a pressure sensor interface. The position of the water pump connecting pipe is higher than that of the flow sensor to form a high-position water pump installation structure, obtaining better supply capacity of the heating water pump.
[0007] The described outlet valve includes a heating water water path control valve, a make-up water valve, a heating water heat exchange plate connecting pipe and a hot water heat exchange plate connecting pipe connected by a connecting plate. The hot water heat exchange plate connecting pipe is respectively communicated with the cold water inlet pipe and the hot water outlet pipe.
[0008] The heating water water path control valve includes a heating water inlet interface, a safety valve interface, a heating water outlet pipe and a heating heat exchange pipe connecting the heating water heat exchange plate connecting pipe.
[0009] The heating hot water entering from the heating water inlet interface is controlled by a water path control device to flow to the heating heat exchange pipe or the heating water outlet pipe; the water path control device includes a first valve rod controlled up and down by a motor. The first valve rod is connected with a first sealing seat and a second sealing seat distributed at intervals. The first sealing seat is cooperatively connected with a first valve port under the control of the first valve rod, and the second sealing seat is cooperatively connected with a second valve port under the control of the first valve rod.
[0010] Adopting the above technical solution, the beneficial effects of the present utility model are as follows: The make-up water valve is communicated with the heating water outlet pipe of the outlet valve through a make-up water outlet pipe to make up water for the heating system, thus solving the technical problem that the outlet valve of the heating water directly makes up water for the heating system. And by installing the make-up water valve on the valve body of the outlet valve, the make-up water inlet pipe of the make-up water valve is communicated with the cold water inlet pipe of the inlet valve. Since the cold water entering the cold water inlet pipe has to flow through the heat exchange plate before entering the make-up water valve, that is, the water entering the make-up water valve is hot water after heat exchange, avoiding the rapid decrease of the water temperature in the heating system.

[0018] As Figures 1-5 shown, a waterway control device with a water replenishing function water outlet valve includes a water inlet valve 2 and a water outlet valve 11. A heat exchange plate 7 is installed between the water inlet valve 2 and the water outlet valve 11. A water replenishing valve 16 is installed on the valve body of the water outlet valve 11. The valve body of the water replenishing valve 16 and the valve body of the water outlet valve 11 are integrally formed. The valve body of the water outlet valve 11 respectively opens a water replenishing inlet pipe 17 and a water replenishing outlet pipe 28 on the side of the valve body of the water replenishing valve 16. A valve rod 31 is installed in the valve body of the water replenishing valve 16, and the valve rod 31 controls whether the water replenishing inlet pipe 17 communicates with the water replenishing outlet pipe 28.
[0019] As a structural preference, the water replenishing inlet pipe 17 communicates with the cold water inlet pipe 1 of the water inlet valve 2, and the water replenishing outlet pipe 28 communicates with the heating water outlet pipe 15 of the water outlet valve. After the valve body of the water outlet valve 11 is drilled to obtain the water replenishing inlet pipe 17, the water replenishing inlet pipe 17 is blocked by the plug 19 in the first plugging pipe 20. After the valve body of the water outlet valve 11 is drilled to obtain the water replenishing outlet pipe 28, the water replenishing outlet pipe 28 is blocked by the plug in the second plugging pipe 22. Through the above structure, the valve rod 31 of the water replenishing valve 16 controls the communication situation between the water replenishing inlet pipe 17 and the water replenishing outlet pipe 28. When the heating system needs to be replenished with water, the cold water inlet pipe 1 is opened, and the cold water reaches the water replenishing inlet pipe 17 through the heat exchange plate 7, passes through the water replenishing valve 16, and reaches the heating water outlet pipe 15 through the water replenishing outlet pipe 28 to replenish the entire heating system with water.
[0020] In order to achieve the high installation of the water pump to improve the water supply capacity, the water inlet valve 2 includes a cold water inlet pipe 1 and a heat exchange water outlet pipe 5. The cold water inlet pipe 1 is respectively connected to the flow sensor 21 and the cold water heat exchange plate connecting pipe 3 by waterways; the heat exchange water outlet pipe 5 is respectively connected to the water pump connecting pipe 4 and the pressure sensor interface 6. The position of the water pump connecting pipe 4 is higher than the pressure sensor interface 6 to achieve the high installation performance of the water pump.
[0021] The water outlet valve 11 includes a heating water waterway control valve, a make-up water valve 16, a heating water heat exchange plate connecting pipe 9, and a hot water heat exchange plate connecting pipe 8 connected by a connecting plate 14. The hot water heat exchange plate connecting pipe 8 is respectively communicated with a cold water inlet pipe 1 and a hot water outlet pipe 18.
[0022] The heating water waterway control valve includes a heating water inlet interface 12, a safety valve interface 13, a heating water outlet pipe 15, and a heating heat exchange pipe 10 connected to the heating water heat exchange plate connecting pipe 9. The heating hot water entering through the heating water inlet interface 12 is controlled by a waterway control device to flow to the heating heat exchange pipe 10 or the heating water outlet pipe 15; the waterway control device includes a first valve rod 23 controlled up and down by a motor. The first valve rod 23 is connected with a first sealing seat 24 and a second sealing seat 26 distributed at intervals. The first sealing seat 24 is cooperatively connected with a first valve port 25 under the control of the first valve rod 23, and the second sealing seat 26 is cooperatively connected with a second valve port 27 under the control of the first valve rod 23.
[0023] The specific process controlled by the waterway control device is as follows: The motor controls the first valve rod 23 to move downward, and the first sealing seat 24 fits and seals with the first valve port 25. The heating hot water flowing in through the heating water inlet interface 12 heats the entire household heating system through the heating water outlet pipe 15. On the contrary, the motor controls the first valve rod 23 to move upward, and the second sealing seat 26 fits and seals with the second valve port 27. The heating hot water flowing in through the heating water inlet interface 12 passes through the heating heat exchange pipe 10, through the heating water heat exchange plate connecting pipe 9, reaches the heat exchange plate 7, passes through the heat exchange water outlet pipe 5 and the water pump connecting pipe 4 to reach the water pump, and completes the heat exchange of the cold water flowing in through the cold water inlet pipe 1 into hot water and flows out through the hot water outlet pipe 18 to form domestic hot water.
