Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a hydraulic module used for heat exchange equipment. Background Art

[0002] At present, the hydraulic module used in heat exchange equipment is an important component of heat exchange equipment, mainly used for the circulation and transportation of refrigerant water, cooling water and sanitary hot water in central air-conditioning water systems (such as ground source heat pumps, air source heat pumps, etc.).

[0003] However, in practice, it is found that the hydraulic modules commonly used in heat exchange equipment on the market are not designed with expansion tanks to relieve the pressure of the inner tank, as described in the "A New Integrated Hydraulic Module System" disclosed in patent number "202221176896.5". As a result, the inner tank runs under unstable pressure for a long time, which can easily lead to rupture of the inner tank or leakage of the pipeline, posing a threat to the safety of equipment and personnel, and also accelerating the wear and aging of equipment and pipelines, shortening the service life of the equipment.

[0004] Therefore, it is necessary to provide a hydraulic module for heat exchange equipment to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the utility model is described in detail below with reference to the drawings.

[0020] See also Figure 1 The hydraulic module for heat exchange equipment of this embodiment includes an inner tank body 1 and an expansion tank 2 arranged below the inner tank body 1. The lower end of the inner tank body 1 is provided with a pressure relief pipe 3 interconnected with the expansion tank 2. A water pump 21 is arranged in the expansion tank 2. The lower end of the inner tank body 1 is also connected with a sewage filter 11 and a water inlet pipe 12 connected with the inner tank body 1. The lower end of the water inlet pipe 12 is connected with the water pump 21. A check valve 13 is provided on the water inlet pipe 12. The lower end of the water pump 21 is connected with a multi-way directional control valve 22 passing through the expansion tank 2.

[0021] In this embodiment, when the water pump 21 is working, the fluid inside the inner tank body 1 can enter the water pump 21 through the check valve 13, which can prevent the fluid from flowing back when the system is closed, so as to protect the water pump 21 and other equipment from damage. At the same time, the present application can also select and adjust the performance of the water pump such as flow rate and head according to specific needs. The present application can achieve precise control of the fluid flow rate by controlling the speed of the water pump 21 or adjusting the valve. After the water pump 21 pressurizes the fluid, the pipeline connected to the multi-way directional control valve 22 can be expanded and connected according to actual needs, which is convenient for integration with other equipment or systems. The present application can enter various radiators / heating equipment through the multi-way directional control valve 22, thereby providing a stable fluid supply for various heat exchange equipment and ensuring the normal operation of the system.

[0022] In this embodiment, during the operation of the system, the pressure in the inner tank body 1 may change. When the pressure is too high, the excess fluid can flow into the expansion tank 2 through the pressure relief pipe 3, which plays a role in buffering and balancing the pressure. The design of the expansion tank 2 in this application can absorb such pressure changes and ensure the stable operation of the system.

[0023] In this embodiment, the sewage filter 11 is located at the lower end of the inner tank body 1, and is used to intercept and remove impurities and dirt in the inner tank body 1. Regular cleaning of the sewage filter 11 can keep the system clean and running efficiently.

[0024] In this embodiment, the expansion tank 2 and the pressure relief pipe 3 together constitute a pressure regulating system, which can automatically balance the pressure in the inner tank body 1, thereby preventing system damage or failure caused by excessively high or low pressure and improving the stability and safety of the system.

[0025] In this embodiment, the present application realizes the functions of fluid circulation, pressure regulation, filtration and sewage discharge through the coordinated work of key components such as the water pump 21, the expansion tank 2, and the sewage filter 11. These functions jointly ensure the stable operation and efficient heat exchange of the system, and provide a reliable fluid supply and control system for various heat exchange equipment.

[0026] Preferably, the sewage filter 11 includes a sewage pipe 111 connected to the lower end of the inner tank body 1 and communicating with the interior of the inner tank body 1 , and a sewage check valve 112 is detachably connected to the lower end of the sewage pipe 111 .

[0027] In this embodiment, the drain pipe 111 is directly connected to the inner tank body 1, so that impurities and dirt in the inner tank can be directly discharged through the drain pipe, avoiding complicated disassembly and cleaning processes. The detachable design of the drain check valve 112 allows the user to easily disassemble and clean it, effectively preventing the filter from being blocked and ensuring the normal operation of the system.

[0028] See also Figure 2 Another inner liner body 4 is provided above the inner liner body 1, and the other inner liner body 4 is connected to the inner liner body 1 through a connecting pipe 41. An exhaust valve port 14 is provided at the top of the other inner liner body 4, and inner liner pipe ports 15 communicating with the interior are provided on both sides of the other inner liner body 4.

[0029] In this embodiment, the two inner tank bodies, namely the inner tank body 1 and the other inner tank body 4, in the design of the present application allow for layered heating, which means that when the water consumption is small, only one inner tank needs to be heated, while the other inner tank can remain in standby mode. This design can significantly save energy because there is no need to heat the water in the entire inner tank of the electric water heater.

[0030] In this embodiment, the user can choose to heat one or two inner tanks according to the actual water consumption. When the water consumption is high, two inner tanks working at the same time can provide more hot water, and when the water consumption is low, it is more efficient to use only one inner tank.

[0031] In this embodiment, the split design allows each liner to be maintained and repaired individually, reducing the downtime of the entire equipment and improving the availability and maintenance efficiency of the equipment.

[0032] In this embodiment, the exhaust valve port 14 is located at the top of the other inner tank body 4, which can effectively remove the gas generated in the inner tank during heating or operation to prevent excessive pressure caused by gas accumulation. At the same time, the existence of the exhaust valve port 14 helps to timely remove the gas in the inner tank and avoid mixing of gas and water, thereby maintaining the purity of water quality. This is of great significance for equipment that requires high-quality water, such as water heaters, water dispensers, etc.

[0033] In this embodiment, when there is only one inner liner on the hydraulic module, that is, only the inner liner body 1, the exhaust valve port 14 and the inner liner pipe port 15 can be set on the inner liner body 1. If there are two inner liner on the hydraulic module, that is, the inner liner body 1 and another inner liner body 4, the exhaust valve port 14 and the inner liner pipe port 15 can be set on the other inner liner body 4.

[0034] Preferably, the number of the water pumps 21 is directly proportional to the number of the inner tanks.

[0035] In this embodiment, when there is only one inner tank on the hydraulic module, that is, only the inner tank body 1, correspondingly, a water pump 21 is provided in the expansion tank 2. If there are two inner tanks on the hydraulic module, that is, the inner tank body 1 and another inner tank body 4, two water pumps 21 can be provided in the expansion tank 2. Obviously, each inner tank can be controlled by an independent water pump 21 for water circulation and heating. This design allows the user or system to independently control the heating and water supply of each inner tank according to actual needs, thereby improving the efficiency and flexibility of the entire system. At the same time, with two inner tanks and two water pumps, the hydraulic module can heat and store more hot water at the same time, increasing the hot water supply capacity of the system, which is particularly important in applications that require a large amount of hot water, such as large residential, commercial buildings or industrial uses. In addition, even if one water pump or inner tank fails, the other water pump and inner tank can still continue to work to ensure the basic operation of the system. This redundant design improves the reliability and stability of the system.

[0036] In this embodiment, in different time periods or usage scenarios, the two tanks and the two water pumps can be operated separately or simultaneously as needed to meet different water demands. For example, during peak water use, the two tanks and the two water pumps can work simultaneously to meet a large amount of water demand; while during low water use, only one tank and one water pump can be used for energy-saving operation.

[0037] In this embodiment, the selection of the multi-way directional control valve 22 depends on the specific requirements and configuration of the hydraulic module, that is, when there is only one water pump 21 in the expansion tank 2, the multi-way directional control valve 22 can be a three-way pipe valve, and when there are two water pumps 21 in the expansion tank 2, the multi-way directional control valve 22 can be a two-way pipe valve.

[0038] Preferably, the upper end of the water inlet pipe 12 and the upper end of the pressure relief pipe 3 are respectively inserted into the interior of the inner tank body 1 from bottom to top and extend out of the inner bottom end of the inner tank body 1, and the upper end of the sewage pipe 111 is inserted into the interior of the inner tank body 1 from bottom to top and is flush with the inner bottom end of the inner tank body 1.

[0039] In this embodiment, the water inlet pipe 12 and the pressure relief pipe 3 extend into the interior of the inner tank body 1, and their upper ends are higher than the height of the sewage pipe 111. Such a design can ensure that the sediment, impurities and dirt generated in the inner tank body 1 will not enter other parts of the device or the external system through the water inlet pipe 12 or the pressure relief pipe 3. And because the water inlet pipe 12 will not contact the impurities at the bottom of the inner tank, the water entering the device can maintain a high degree of purity. This is especially important for equipment that requires high-quality water quality, such as water heaters, drinking water heaters, etc. The accumulation of impurities and dirt may cause pipe blockage or damage, and this design can effectively prevent this from happening, thereby extending the service life of the pipe and the entire equipment.

[0040] Preferably, the water inlet pipe 12 includes a water inlet pipe port 121 whose upper end extends into the interior of the inner tank body 1 and a water inlet pipe 122 whose lower end is connected to the water pump 21 , and the upper end of the water inlet pipe 122 is screwed to the lower end of the water inlet pipe port 121 .

[0041] In this embodiment, the water inlet pipe 122 is connected to the water inlet pipe port 121 by screw connection, which is simple, reliable, and easy to install and disassemble. When the water inlet pipe needs to be cleaned, repaired, or replaced, it can be easily disassembled and reinstalled, which improves the convenience of maintenance. The screw connection method can ensure that the water inlet pipe 122 is tightly connected to the water inlet pipe port 121, effectively preventing water leakage caused by loose connection. This ensures that the equipment can stably supply water during operation, avoiding waste of resources and safety hazards caused by water leakage.

[0042] In this embodiment, since the water inlet pipe 122 is screwed to the water inlet port 121, the length and angle of the pipe can be easily adjusted as needed to adapt to different installation environments and space requirements. At the same time, when the pipe is worn or damaged, it can be easily replaced with a new pipe, extending the service life of the equipment.

[0043] Preferably, the pressure relief pipe 3 includes a first pressure relief pipe opening 31 whose upper end extends into the interior of the inner tank body 1, a second pressure relief pipe opening 32 whose lower end extends into the interior of the expansion tank 2, and a pressure relief pipe 33 screwed between the first pressure relief pipe opening 31 and the second pressure relief pipe opening 32.

[0044] In this embodiment, when the internal pressure of the liner body 1 exceeds the set value, the pressure can be quickly released into the expansion tank 2 through the first pressure relief pipe port 31 and the pressure relief pipe 33, and enter through the second pressure relief pipe port 32, thereby effectively reducing the pressure in the liner. This design can respond quickly to pressure changes and ensure the safe operation of the equipment. The pressure relief pipe 33 is connected to the first pressure relief pipe port 31 and the second pressure relief pipe port 32 by screwing, which is convenient for installation, disassembly and maintenance. When the pressure relief pipeline needs to be cleaned, inspected or replaced, it can be easily disassembled and reinstalled, reducing the difficulty of maintenance. The screw connection method ensures a tight connection between the first pressure relief pipe port 31, the pressure relief pipe 33 and the second pressure relief pipe port 32, effectively preventing leakage problems caused by loose connections. This ensures that the system can still operate stably under high pressure conditions, avoiding waste of resources and safety hazards.

[0045] In this embodiment, the design of a threaded interface for the multi-way directional control valve 22 to be screwed on the lower end of the water pump 21 brings the following specific benefits: convenient installation and disassembly, tight connection to prevent leakage, strong adaptability, bearing a certain pressure, convenient maintenance and replacement, and improved system stability. This design is of great significance in practical applications and can meet the needs of different occasions.
