Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of material testing equipment, and in particular relates to a high-temperature and high-speed water-oxygen corrosion device. Background Technology
[0002] Water-oxygen corrosion apparatus can simulate the corrosion conditions that materials may suffer in actual industrial environments, providing important basis for material selection, design, and optimization. Its functions include generating and maintaining a high-temperature, high-pressure water environment, controlling dissolved oxygen content, adjustable experimental parameters, data acquisition and analysis, and safety assurance measures. The system typically operates at temperatures up to several hundred degrees Celsius.
[0003] For example, the application of water-oxygen corrosion testing equipment in aero-engine blade testing is reflected in several aspects, including material corrosion resistance assessment. It can simulate the complex environment during aero-engine operation, conduct long-term corrosion tests on blade materials to understand their corrosion rate, morphology, and products, and also test the integrity, bonding strength, and impermeability of protective coatings. It can be used for stress corrosion cracking research, working in conjunction with stress loading equipment to simulate the working conditions of blades under the combined action of stress, water, and oxygen, and determine parameters such as stress corrosion cracking threshold and crack propagation rate. It is helpful for corrosion mechanism research, allowing for the observation and analysis of corrosion behavior under different conditions to understand the corrosion process and mechanism of blade materials, providing theoretical support for new corrosion-resistant materials and protection technologies. It can compare the performance of different materials and processes, evaluate and select materials and manufacturing processes in the aero-engine blade development process. It can also conduct accelerated aging tests, accelerating the corrosion process of blade materials by increasing the test environment parameters, providing a reference for blade reliability assessment and life prediction.
[0004] However, existing water-oxygen corrosion testing devices have many problems, such as: in terms of temperature control, there is a limitation in the temperature range. The test temperature of some devices cannot meet the requirements of wide temperature range and long-term operation. When studying water-oxygen corrosion of special materials or extreme working conditions, the temperature conditions of existing high-temperature water-oxygen corrosion test devices are insufficient, and it is difficult to simulate the temperature gradient. For test pieces with complex configurations and temperature differences, such as hot-end components of aero-engines, it is difficult to accurately simulate the corrosion under temperature gradient conditions. In terms of precise control of test parameters, the water-oxygen ratio control accuracy has errors, which affects the accuracy of test results. The flow rate and flow volume control are not precise enough under complex working conditions such as high temperature, and the use of flow meters, velocity meters and other equipment is limited. In terms of equipment integration and ease of operation, the equipment integration is not high enough. The functional modules of some devices are scattered. The assessment of the thermal cycling performance and resistance to isothermal water-oxygen corrosion of materials needs to be carried out on different devices, which is time-consuming, labor-intensive and increases experimental safety hazards. Utility Model Content
[0005] In view of this, the present invention aims to provide a high-temperature and high-speed water-oxygen corrosion device in order to solve some or all of the technical problems mentioned in the background art.
[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0007] A high-temperature, high-speed water-oxygen corrosion device includes a water-oxygen corrosion chamber, a water-oxygen corrosion insulation chamber, a water tank, a steam generator, a liquid flow controller, a gas flow controller, an integrated frame, a heating element, and an electrical controller.
[0008] The water-oxygen corrosion insulation chamber includes an outer shell, an insulation layer, and a refractory layer. The water-oxygen corrosion chamber extends through the insulation chamber. The refractory layer and the external protrusion of the water-oxygen corrosion chamber cooperate to form a heating chamber. The insulation layer covers the refractory layer and the outside of the water-oxygen corrosion chamber. The outer shell of the insulation chamber is located outside the insulation layer. The heating element is located inside the heating chamber. The heating element is a silicon molybdenum rod. The water-oxygen corrosion insulation chamber can effectively prevent heat loss and keep the temperature inside the water-oxygen corrosion chamber above 1600℃ for a long time.
[0009] The refractory layer of an insulated warehouse plays a crucial role. First, it provides a stable support structure for the insulation layer. Since the insulation layer is relatively soft, such as some fibrous materials, the refractory layer allows it to be evenly laid on top, preventing deformation or collapse due to its own weight or external pressure. Second, it prevents the insulation layer from being damaged by heat. Because the insulation material has limited temperature resistance, direct contact with high temperatures without the refractory layer can cause it to deteriorate and lose its insulation properties. Finally, the refractory layer reduces the rapid transfer of heat to the insulation layer. The primary function of the insulation layer is to reduce heat loss, but if heat is transferred too quickly, it may exceed the insulation layer's capacity, leading to excessive heat loss. The refractory layer has a low thermal conductivity, forming a thermal resistance layer between the heating element and the insulation layer, allowing heat to be transferred to the insulation layer at a more suitable rate, thus maximizing the insulation effect.
[0010] The integrated frame consists of a water vapor generating end and an electrical heating end, with the water vapor generating end on one side and the electrical heating end on the other side.
[0011] The water-oxygen corrosion insulation chamber and electrical controller are located inside the electrical heating end. The heating element extends out of the water-oxygen corrosion insulation chamber and connects to the insulator. The heating part of the heating element is inside the heating chamber and is connected to the insulator through a wire. The insulator is electrically connected to the electrical controller through a copper busbar. The opening end of the water-oxygen corrosion chamber is located on the outside of one side of the integrated frame electrical heating end for easy handling of test materials.
[0012] The water tank, steam generator, liquid flow controller, and gas flow controller are installed inside the water vapor generation end. The water tank is connected to the steam generator via a pipeline, and the steam generator is connected to one end of the water-oxygen corrosion chamber via a pipeline. The liquid flow controller is electrically connected to the water tank and the steam generator. There are two sets of gas flow controllers: one set is connected to the steam generator pipeline, and the other set is connected to one end of the water-oxygen corrosion chamber pipeline. All pipelines connected to the water-oxygen corrosion chamber are connected to the same end. The water tank, under the control of the liquid flow controller, quantitatively delivers liquid to the steam generator, and the steam generator can reach... The input liquid is vaporized at 120℃, completing the initial heating process, and then transported into the water-oxygen corrosion chamber. A gas flow controller can quantitatively deliver high-pressure gas to the water-oxygen corrosion chamber. Simultaneously, another gas flow controller can input high-pressure gas into a steam generator to form high-pressure steam. Therefore, this device has four basic gas combination methods: First, input of self-pressurized steam from the steam generator to form ordinary water-gas impact; second, independent input of high-pressure gas to form high-pressure, high-speed airflow impact; third, mixed input of self-pressurized steam and high-pressure gas to form high-speed water-gas impact; fourth, mixed input of high-pressure steam and high-pressure gas to form extreme high-speed, high-pressure water-gas impact. Furthermore, depending on the different input gases and pressure differences, this device can generate more test combinations. The gas flow controller is a mass flow controller. Further, it also includes an air inlet and an air inlet switch, which are located on the outside of the integrated frame. The air inlet is connected to the gas flow controller, and the air inlet switch controls whether gas is supplied to the gas flow controller.
[0013] The electrical controllers are electrically connected to the water tank, steam generator, liquid flow controller, and gas flow controller, respectively.
[0014] In a structure that optimizes the aforementioned solution, the water-oxygen corrosion insulation chamber is positioned above the electrical heating end, and the electrical controller is positioned below the electrical heating end. Due to the high integration of this equipment, the above arrangement can effectively control the operating temperature of the electrical controller, preventing damage or other hazards caused by excessively high operating temperatures of the electrical equipment.
[0015] In a structure that optimizes the aforementioned solution, an internal displacement fan is also included, which is located at the bottom of the water-oxygen corrosion insulation chamber. The internal displacement fan blows air from bottom to top, which can effectively prevent the surface temperature rise of the water-oxygen corrosion insulation chamber, prevent the sealing rings in various parts of the equipment from aging too quickly, and ensure that the electrical components operate below 70°C.
[0016] In a structure that optimizes the aforementioned solution, an external displacement fan is also included. This external displacement fan is mounted on an integrated frame at the rear of the water-oxygen corrosion insulation chamber. The external displacement fan blows air from the outside into the electrical heating element, further controlling the surface temperature rise of the internal equipment. Preferably, two sets of external displacement fans are horizontally arranged.
[0017] In a structure that optimizes the aforementioned solution, a water level indicator is also included. The water level indicator is located on the outside of the water vapor generator end of the integrated frame and connected to the water tank pipeline. Furthermore, a water inlet is also provided on the outside of the water vapor generator end of the integrated frame. The water inlet is connected to the water tank, and the water level in the water tank can be observed through the water level indicator. When the water level is too low, water can be added in time through the water inlet.
[0018] In a structure that optimizes the aforementioned solution, an air vent valve is installed at the top of the water tank. The air vent valve at the top of the water tank serves to expel air and maintain pressure balance within the tank. During initial water filling, air can easily enter the tank with the water flow. The air vent valve can promptly expel this air; otherwise, air accumulation at the top of the tank would occupy space, reducing the actual water storage capacity and affecting normal water storage function. During daily operation, as water continuously enters and exits the tank from the water supply system, a small amount of air may re-enter due to water flow disturbances. The air vent valve can promptly expel this air, ensuring relatively pure water quality within the tank, preventing an increase in dissolved oxygen due to air presence, and reducing the possibility of rust and corrosion of metal components within the tank. Meanwhile, the vent valve can maintain the pressure balance inside the water tank. When the water temperature inside the tank changes (such as the water temperature in the hot water tank rises) or the water inflow and outflow changes, causing pressure fluctuations, the vent valve can act as a safety valve when the pressure rises. It will automatically open when the pressure reaches a certain threshold, releasing some gas (air or water vapor, etc.) to reduce the pressure and prevent damage such as water tank rupture or deformation, thus ensuring the safety of the water tank and the entire water supply system. When the pressure is too low (such as when a large amount of water is used, causing the water level in the tank to drop rapidly, the space to increase, and the pressure to decrease), the vent valve helps to detect the problem, because continuous low pressure may mean that there is a leak in the water tank. By checking the status of the vent valve, the pressure situation can be assessed so that measures such as replenishing water can be taken in time to restore normal pressure and maintain the normal water supply function of the water tank.
[0019] In a structure that optimizes the aforementioned solution, a control panel is also included. This control panel is located at the front of the integrated frame and is electrically connected to the electrical controller. Since the control panel is electrically connected to the electrical controller, it is primarily used for operating and controlling the entire high-temperature, high-speed water-oxygen corrosion device. Through the control panel, operators can set and adjust the operating parameters of various components. For example, the water supply to the water tank can be set, which requires controlling a liquid flow controller. The liquid flow controller is connected to the electrical controller, and the control panel can send commands to the electrical controller to control the operating state of the liquid flow controller, thereby precisely controlling the water supply to the water tank. Parameters such as the temperature and pressure of the steam generator can also be adjusted through the control panel. Because the operating state of the steam generator is controlled by the electrical controller, the control panel, as a human-machine interface, allows input commands to change parameters such as the power supply to the steam generator, thereby controlling its internal temperature and the pressure of the generated steam. Simultaneously, the gas flow controller's control of the gas input into the water-oxygen corrosion chamber can also be operated via the control panel. Different gas combination methods can be selected, such as self-pressurized steam input from the steam generator, independent input of high-pressure gas, mixed input of self-pressurized steam and high-pressure gas, or mixed input of high-pressure steam and high-pressure gas. The control panel sends signals to the electrical controller, thereby precisely controlling the operation of the gas flow controller to meet the requirements of the gas environment inside the water-oxygen corrosion chamber under different test conditions.
[0020] In a structure that optimizes the aforementioned solution, an upper exhaust panel is also included, which is located on top of the integrated frame. During device operation, the water-oxygen corrosion chamber operates in a high-temperature environment, and the steam generator produces high-temperature steam, generating a large amount of hot air inside the device. Since hot air tends to rise, the upper exhaust panel can expel this internal hot air. Simultaneously, the expulsion of internal hot air creates a localized low-pressure area, allowing external cold air to be drawn in through the upper exhaust panel or through airflow channels formed with internal and external displacement fans, creating air circulation. This circulation helps to remove heat from the device, maintaining the internal equipment temperature from becoming too high. The upper exhaust panel is a crucial top exhaust channel in the heat dissipation process. Combined with other heat dissipation components such as exhaust fans, it can more effectively regulate the internal temperature environment of the device. For example, in high-temperature, high-speed water-oxygen corrosion testing, temperature-sensitive equipment such as electrical controllers can maintain the ambient temperature within a suitable range through this circulation of hot air expulsion and cold air intake, preventing malfunctions due to overheating.
[0021] In a structure that optimizes the aforementioned solution, a side exhaust panel is also included, which is located on the lower part of the left, right, and rear sides of the integrated frame. The side exhaust panel, located on the lower part of the left, right, and rear sides of the integrated frame, is mainly used to exhaust hot air accumulated in the lower parts of the device due to obstruction by components. Simultaneously, it can also draw in external air. After exhausting the internal hot air, external air can enter the device through device gaps or through air intake channels that cooperate with the internal and external displacement fans. This air exchange can balance the internal temperature distribution of the device and prevent localized overheating. The side exhaust panel, together with the upper exhaust panel, internal displacement fan, and external displacement fan, form a three-dimensional air circulation system. For example, the internal displacement fan blows air upwards, causing the hot air at the bottom to rise; the side exhaust panel exhausts the hot air in the lower position; the upper exhaust panel exhausts the hot air at the top; and the external displacement fan blows in cool air from the outside. Together, they maintain the internal equipment temperature within a reasonable range, ensuring stable operation and extending the equipment's service life.
[0022] Compared with existing technologies, the high-temperature, high-speed water-oxygen corrosion device of this invention has the following advantages:
[0023] 1. In terms of temperature control, the water-oxygen corrosion insulation chamber structure of this device has significant advantages. Its unique insulation chamber shell, insulation layer, refractory insulation chamber layer and heating element (silicon molybdenum rod) work together to maintain the internal temperature of the water-oxygen corrosion chamber above 1600℃ for a long time, breaking through the problem of limited temperature range in existing technologies and meeting the temperature requirements of water-oxygen corrosion research on more special materials and extreme working conditions.
[0024] 2. The design of the water-oxygen corrosion insulation chamber is of positive significance for temperature gradient simulation. By rationally arranging heating elements and optimizing the insulation structure, it is possible to more accurately simulate the corrosion under temperature gradient conditions for test pieces with complex configurations and temperature differences, such as hot-end components of aero-engines, providing an environment that is more in line with actual working conditions for research.
[0025] 3. The three-dimensional air circulation system, consisting of an internal displacement fan, an external displacement fan, an upper exhaust panel, and a side exhaust panel, effectively controls the equipment temperature. It prevents water and oxygen corrosion of the insulation chamber surface, ensures electrical components operate below 70℃, avoids premature aging of sealing rings, extends equipment life, maintains a stable temperature gradient, and improves the accuracy and reliability of experimental results.
[0026] 4. For precise control of test parameters, the liquid flow controller and the gas flow controller (mass flow controller) played a crucial role. The liquid flow controller can accurately control the amount of water supplied from the water tank to the steam generator, while the gas flow controller can accurately regulate the amount of gas delivered to the water-oxygen corrosion chamber. The combination of the two solved the problem of accuracy error in water-oxygen ratio control, creating an accurate and stable water-oxygen environment for the experiment.
[0027] 5. Under complex high-temperature conditions, the liquid flow controller and gas flow controller still perform excellently. They can ensure precise control of the flow rate and volume of liquids and gases. Whether it is the amount of water vapor generated by the steam generator or the amount and proportion of various gases entering the water-oxygen corrosion chamber, they can be accurately adjusted as needed, greatly improving the accuracy of test results and making the experimental data more scientific and valuable for reference.
[0028] 6. The integrated frame significantly improves the equipment integration. It integrates the water and gas generation end (water tank, steam generator, liquid flow controller, gas flow controller) and the electrical heating end (water-oxygen corrosion insulation chamber, electrical controller). The opening end of the water-oxygen corrosion chamber is reasonably set, overcoming the problems of low equipment integration and scattered functional modules in the existing technology. It reduces the trouble of switching equipment when different performance tests are performed and improves experimental efficiency.
[0029] 7. The control panel enhances ease of operation. Located at the front of the integrated frame and electrically connected to the electrical controller, it allows operators to easily and centrally set and adjust parameters of various components (such as liquid flow rate, gas flow rate, temperature, etc.). This simplifies operation, reduces operational difficulty and workload, improves the usability and practicality of the device, and minimizes experimental safety hazards. Attached Figure Description

[0041] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0042] 1. Equipment Structure
[0043] This high-temperature, high-speed water-oxygen corrosion device mainly consists of the following parts:
[0044] Water-oxygen corrosion insulation chamber 2: It includes an outer shell 21, an insulation layer 22, and a refractory layer 23. A water-oxygen corrosion chamber 1 extends through it, and the refractory layer 23 and the external protrusion of the water-oxygen corrosion chamber 1 cooperate to form a heating chamber 9. A silicon molybdenum heating element is placed inside the heating chamber 9. The refractory layer 23 provides support for the insulation layer 22, preventing it from deforming or collapsing due to its own weight or external forces. It also prevents damage to the insulation layer 22 due to high temperatures and reduces the rapid transfer of heat to the insulation layer 22, allowing the internal temperature of the water-oxygen corrosion chamber 1 to be maintained above 1600℃ for an extended period.
[0045] The integrated frame 7 consists of a water vapor generating end and an electrical heating end. The water-oxygen corrosion insulation chamber 2 and the electrical controller (not shown in the attached diagram) are located inside the electrical heating end. The opening of the water-oxygen corrosion chamber 1 is on the outside of the electrical heating end for easy access to test materials. The heating element (not shown in the attached diagram) is electrically connected to the electrical controller via an insulator 8. The water tank 3, steam generator 4, liquid flow controller 5, and gas flow controller 6 are located inside the water vapor generating end. The water tank 3 is piped to the steam generator 4, and the steam generator 4 is piped to one end of the water-oxygen corrosion chamber 1. The liquid flow controller 5 is electrically connected to both the water tank 3 and the steam generator 4. There are two sets of gas flow controllers 6, each connected to one end of the pipes of the steam generator 4 and the water-oxygen corrosion chamber 1, respectively, allowing for various gas input combinations. Additionally, it includes an air inlet 16 and an air inlet switch 17. The air inlet 16 and air inlet switch 17 are located on the outside of the integrated frame 7. The air inlet 16 is connected to the gas flow controller 6, and the air inlet switch 17 controls whether gas is supplied to the gas flow controller 6.
[0046] Other components: The internal displacement fan 10 is located at the bottom of the water-oxygen corrosion insulation chamber 2; the external displacement fan 11 is located on the integrated frame 7 at the rear of the water-oxygen corrosion insulation chamber 2; the water level indicator 31 is located outside the water-air generating end of the integrated frame 7 and is connected to the water tank 3 via a pipe; the water inlet 15 is located outside the water-air generating end of the integrated frame 7 and is connected to the water tank 3; the water tank 3 has an air vent valve 32 on its upper part; the control panel 12 is located at the front of the integrated frame 7 and is electrically connected to the electrical controller; the upper exhaust panel 13 is located at the top of the integrated frame 7; and the side exhaust panels 14 are located at the lower parts of the left, right, and rear sides of the integrated frame 7.
[0047] The water-oxygen corrosion insulation chamber 2 is a key component for achieving high temperatures. Its unique structure includes an outer shell 21, an insulation layer 22, and a refractory insulation layer 23. The water-oxygen corrosion chamber 1 runs through it, and the refractory insulation layer 23, in conjunction with external protrusions of the water-oxygen corrosion chamber 1, forms a heating chamber 9, within which a silicon molybdenum heating element is placed. The refractory insulation layer 23 plays a crucial role, providing stable support for the insulation layer 22, preventing deformation or collapse due to its own weight or external pressure, and protecting it from damage due to direct contact with high temperatures. Furthermore, it reduces the rapid heat transfer to the insulation layer 22, ensuring heat is transferred at an appropriate rate, maximizing the insulation effect of the insulation layer 22, and ultimately maintaining the internal temperature of the water-oxygen corrosion chamber 1 above 1600℃ for extended periods, meeting the high-temperature requirements.
[0048] The gas flow controller 6 within the integrated frame 7 is a crucial factor in achieving high speed. There are two sets of gas flow controllers 6: one connected to the piping of the steam generator 4, and the other connected to one end of the piping of the water-oxygen corrosion chamber 1. Controlled by the control panel 12, the gas flow controller 6 can quantitatively deliver high-pressure gas to the water-oxygen corrosion chamber 1, and can also input high-pressure gas into the steam generator 4 to form high-pressure steam. This allows for four basic gas combination methods: self-pressurized steam input from the steam generator 4, independent high-pressure gas input, mixed input of self-pressurized steam and high-pressure gas, and mixed input of high-pressure steam and high-pressure gas. Furthermore, the gas inlet 16 can be controlled via the inlet switch 17 to supply gas to the gas flow controller 6, thus enabling even more test combinations. These different gas input methods create a high-speed airflow environment within the water-oxygen corrosion chamber 1, meeting high-speed requirements.
[0049] 2. Equipment operation process
[0050] Start the electrical controller and set the parameters via control panel 12. Send commands to the electrical controller via control panel 12 to control the liquid flow controller 5. The water tank 3, according to the control of the liquid flow controller 5, delivers liquid quantitatively to the steam generator 4. The steam generator 4 vaporizes the input liquid and heats it to 120°C before delivering it into the water-oxygen corrosion chamber 1.
[0051] Meanwhile, the gas flow controller 6 is controlled by the control panel 12. The gas flow controller 6 can quantitatively deliver high-pressure gas to the water-oxygen corrosion chamber 1, or input high-pressure gas into the steam generator 4 to form high-pressure steam. This enables four basic gas combination modes for the steam generator 4: self-pressurized steam input, independent high-pressure gas input, mixed input of self-pressurized steam and high-pressure gas, and mixed input of high-pressure steam and high-pressure gas. In addition, the air inlet switch 17 can control whether the air inlet 16 delivers gas to the gas flow controller 6, thereby generating more test combination modes.
[0052] During operation, the heating element continuously heats the water-oxygen corrosion chamber 1 to a high temperature. The steam generated by the steam generator 4 and the gas supplied by the gas flow controller 6 create a high-temperature, high-speed water-oxygen environment within the water-oxygen corrosion chamber 1 to perform corrosion tests on the test materials placed inside.
[0053] The internal displacement fan 10 blows air from bottom to top, while the external displacement fan 11 blows air into the electrical heating end from the outside. The upper exhaust panel 13 exhausts the internal hot air and draws in the external cold air, while the side exhaust panel 14 exhausts the hot air from the lower part of the device and draws in the external air. These components work together to form an air circulation, preventing water and oxygen from corroding the surface temperature rise of the insulation chamber 2, ensuring that the electrical components operate below 70°C, maintaining the internal equipment temperature within a reasonable range, avoiding premature aging of the sealing rings, and ensuring stable operation of the device.
[0054] The water level indicator 31 displays the water level in the water tank 3 in real time. When the water level is too low, water can be added through the inlet 15. The air vent 32 on the top of the water tank 3 can expel air and maintain the pressure balance inside the water tank, ensuring the normal operation of the water tank and the water supply function.
[0055] Formation and Maintenance of the High-Temperature Environment: After starting the electrical controller, parameters are set via the control panel 12 to control the operation of the liquid flow controller 5. The water tank 3, according to its control, quantitatively supplies liquid to the steam generator 4. The steam generator 4 vaporizes the liquid and heats it to 120°C before introducing it into the water-oxygen corrosion chamber 1. Simultaneously, the heating element continuously heats the chamber, working in conjunction with the insulation structure of the water-oxygen corrosion chamber to maintain a high-temperature state within the chamber 1. This high-temperature environment persists throughout the entire operation, providing the necessary high-temperature corrosion conditions for the test materials.
[0056] Creating a high-speed water-oxygen environment: During device operation, the gas supplied by the gas flow controller 6 and the water vapor generated by the water vapor generator 4 mix within the water-oxygen corrosion chamber 1. Through the quantitative supply of gas by the gas flow controller 6 and various gas combination methods, a high-speed water-oxygen environment can be created within the water-oxygen corrosion chamber 1. For example, when selecting independent input of high-pressure gas or a mixed input of high-pressure water vapor and high-pressure gas, a high-speed airflow impact can be generated, meeting the conditions for high-temperature, high-speed water-oxygen corrosion testing of the test materials. Furthermore, the air circulation system formed by the internal displacement fan 10, external displacement fan 11, upper exhaust panel 13, and side exhaust panel 14 maintains a stable internal temperature while ensuring the normal operation of the high-temperature, high-speed water-oxygen environment within the water-oxygen corrosion chamber 1.
[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
