[0022] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0023] Example:

[0024] Fluid control technology is widely used in various fields. Two-way valves, as a common fluid control component, play a vital role in industrial production, building facilities, and HVAC systems in everyday life. The primary function of a two-way valve is to regulate and control the fluid medium by controlling the flow of fluid. However, the traditional two-way valve design has certain limitations, which to some extent affect its efficiency and convenience.

[0025] The current two-way valve structure on the market primarily consists of three parts: the valve body, the pilot assembly, and the coil. The valve body is the foundation of the two-way valve and is typically made of metal to ensure strength and corrosion resistance. The pilot assembly is one of the core components of the two-way valve, responsible for receiving control signals and actuating the valve core to achieve fluid flow. The coil is the key component that provides the driving force. By applying electricity, it generates a magnetic field that drives the pilot assembly.

[0026] In traditional two-way valve structures, the pilot assembly and coil are typically connected using a retaining ring. While this assembly method ensures reliable connection, it presents numerous operational inconveniences. First, the nameplate must be installed before assembly, a step that not only complicates the process but also increases assembly time. Second, the installation and removal of the retaining ring requires specialized tools, which increases the difficulty and workload of maintenance. Furthermore, the retaining ring connection may loosen over time due to factors such as vibration and temperature fluctuations, potentially affecting the proper operation of the two-way valve.

[0027] To address the aforementioned issues, the present invention provides a novel two-way valve designed to simplify the assembly process, improve assembly efficiency, and ensure reliability and stability. The valve comprises a valve body 1, a base 2 mounted at the bottom of the valve body 1, and a terminal 3 mounted on one side of the valve body 1. The valve body 1 houses a coil and a pilot head 11 locked to the coil, and a contact piece 13 is provided on one side of the valve body 1. The valve body 1, as the main body of the two-way valve, is still made of high-strength, corrosion-resistant metal to ensure stability and durability in various operating environments.

[0028] In the novel two-way valve of this application, a coil and a pilot head 11, which is locked and connected to the coil, are housed within the valve body 1. This locking connection method abandons the traditional snap ring assembly and adopts a simpler and more reliable connection method, such as a threaded connection or a snap-on connection. A threaded connection secures components by screwing together, offering the advantages of a secure connection and preventing loosening. A snap-on connection, on the other hand, allows for quick assembly through the snap-on engagement, making it easy to operate and highly efficient. Both connection methods not only simplify the assembly process but also significantly reduce assembly time.

[0029] In addition, the new two-way valve features a contact piece 13 on one side of the valve body 1. This piece's primary function is to provide an electrical connection, ensuring proper operation of the coil when energized. The design of this piece takes into account the reliability and safety of the electrical connection. It utilizes highly conductive, corrosion-resistant materials, and features special treatment on the contact surface to ensure optimal contact.

[0030] To further enhance the performance and user experience of the new two-way valve, numerous details have been optimized. For example, the design of the base 2 not only considers a secure connection to the valve body 1 but also facilitates installation, adopting a structure that is easy to fix and remove. The design of the terminal 3 fully considers the diversity and flexibility of electrical connections, providing a variety of interface types to meet the needs of different application scenarios.

[0031] In practical applications, the new two-way valve demonstrates numerous advantages. First, the simplified assembly process significantly improves production efficiency and reduces costs. Second, the reliable connection method ensures the stability and safety of the two-way valve during long-term use. Furthermore, the optimized structural design makes the new two-way valve more convenient in installation and maintenance, enhancing the user experience.

[0032] In short, the design philosophy of the new two-way valve is to simplify the structure, improve efficiency, and enhance the user experience while ensuring performance. By optimizing the connection of key components and refining detailed design, the new two-way valve demonstrates broad application prospects in the field of fluid control. In the future, with the continuous advancement of technology and changes in market demand, the new two-way valve will continue to be iterated and upgraded to meet more diverse and demanding fluid control needs.

[0033] One of the core components of the two-way valve is the pilot head 11, which is responsible for receiving control signals and driving the valve core to move, thereby achieving precise control of the fluid medium. In order to improve the performance and ease of use of the two-way valve, the design and connection method of the pilot head 11 are particularly important. In the design of the present application, the pilot head 11 is provided with a hexagon socket head screw 12, and the pilot head 11 is provided with a hexagon socket head screw 12. The hexagon socket head screw 12 is a specially designed fastener with a hexagonal recess on its head, which is convenient for tightening and disassembly using an hexagonal wrench. This design not only improves the uniformity of the force on the screw, but also enhances its torsion resistance, ensuring that it is not easy to loosen during long-term use.

[0034] The hexagon socket head screw 12 is provided with a sealing gasket 121 made of a metal composite material. The process is simple and easy to assemble. When slightly damaged, it can automatically repair itself without replacement. Its function is to form a reliable sealing barrier between the contact surface of the screw and the pilot head 11 to prevent leakage of the fluid medium and ensure the safe operation of the system. The provision of the sealing gasket 121 not only improves the sealing effect, but also simplifies the assembly process. During the installation process, you only need to put the sealing gasket 121 on the screw and then screw it into the threaded hole of the pilot head 11 to achieve a sealed connection. The operation is simple and efficient.

[0035] Lubricant and nano-lubricating particles are also added to the sealing gasket 121 to reduce the friction coefficient, extend the service life, and reduce wear and maintenance requirements at the screw connection.

[0036] The pilot head 11 is locked and connected to the coil by means of a hexagon socket head screw 12, which reduces the magnetic gap between the pilot head 11 assembly and the coil and increases the magnetic flux. This connection method has multiple advantages. First, the design of the hexagon socket head screw 12 makes the connection more secure and reliable, and is not easily loosened due to factors such as vibration and temperature changes, thereby ensuring the stability and safety of the two-way valve in long-term use. Secondly, the locking connection method effectively reduces the magnetic gap between the pilot head 11 assembly and the coil. The magnetic gap refers to the air gap between the pilot head 11 and the coil, and its size directly affects the efficiency of the magnetic flux transmission. Through precise design and optimized connection methods, the new two-way valve successfully reduces the magnetic gap, allowing the magnetic flux to be transmitted more efficiently, thereby improving the driving efficiency of the coil and the response speed of the pilot head 11.

[0037] Increasing magnetic flux is crucial for improving the performance of two-way valves. Magnetic flux refers to the number of magnetic lines of force per unit area that pass perpendicularly through a plane. It is a key indicator of magnetic field strength and magnetic properties. In a two-way valve, the magnetic field generated by energizing the coil is transmitted to the pilot head 11 via magnetic flux, driving its movement. This increase in magnetic flux means a stronger magnetic field, which in turn provides greater driving force for the pilot head 11, faster response speed, and more sensitive and precise movement. This is crucial for achieving precise control and rapid response of the fluid medium.

[0038] Furthermore, the design of the hexagon socket head screw 12 takes into account ease of maintenance and replacement. During the use of a two-way valve, components inevitably wear and damage, necessitating maintenance and replacement. The use of the hexagon socket head screw 12 simplifies disassembly and installation, requiring only an hexagonal wrench, significantly reducing maintenance time and costs.

[0039] In addition to the connection method between the pilot head 11 and the coil, other design details have also been optimized. For example, the material selection and structural design of the valve body 1 fully consider corrosion resistance and strength requirements, ensuring its stability and durability in various complex environments. The design of the base 2 takes into account both convenient and stable installation, adopting a structure that is easy to fix and remove. The design of the terminal 3 provides a variety of interface options to meet the needs of different application scenarios.

[0040] In practical applications, the new two-way valve of this application has demonstrated significant advantages. The simplified assembly process greatly improves production efficiency and reduces production costs. The reliable connection method ensures the stability and safety of the two-way valve in long-term use. The optimized structural design makes the new two-way valve more convenient in terms of installation and maintenance, improving the user experience. The increase in magnetic flux significantly improves the response speed and accuracy of the two-way valve, meeting the high requirements for precise control of fluid media.

[0041] This application successfully reduces the magnetic gap, increases the magnetic flux, and improves the overall performance by optimizing the connection method between the pilot head 11 and the coil, using a hexagon socket head screw 12 and providing a sealing gasket 121. This innovative design not only simplifies the assembly process and improves production efficiency, but also ensures the stability and reliability of the two-way valve in long-term use. In the future, with the continuous advancement of technology and changes in market demand, the new two-way valve will continue to iterate and upgrade to meet more diverse and demanding fluid control needs, providing strong support for the optimization and development of modern industry and fluid control systems.

[0042] In order to improve the comprehensive performance of the two-way valve, the staff has made many innovations and optimizations in the details. Among them, the design of the pilot head 11 is particularly critical. It is not only responsible for receiving the control signal, but also drives the valve core to move, thereby achieving precise control of the fluid medium. In the design of the new two-way valve of this application, the pilot head 11 is also provided with an electromagnet. The electromagnet is an important component of the pilot head 11 and is tightly integrated with the pilot head 11, which reduces the interfaces and connectors and improves the reliability and maintainability of the system. The magnetic field is generated by powering on, which drives the pilot head 11 to move, thereby controlling the opening and closing of the valve core. The application of electromagnets has significantly improved the response speed and accuracy of the two-way valve, meeting the high requirements for precise control of the fluid medium.

[0043] The electromagnet features an internal thread structure, a design that offers multiple advantages. It reduces material and processing costs, provides a larger surface area for more efficient heat dissipation, and ensures stable performance over extended periods. It also creates a more uniform magnetic field distribution, reducing magnetic field distortion and improving the electromagnet's operating accuracy.

[0044] In order to further improve the stability and reliability of the pilot head 11, a limit groove 14 is provided on the pilot head 11. The main function of the limit groove 14 is to ensure that the pilot head 11 maintains precise displacement and position during the operation, and to prevent performance degradation due to excessive movement or offset. The design of the limit groove 14 fully considers the motion trajectory and force conditions of the pilot head 11, and adopts reasonable geometric shapes and sizes to ensure that it can play a good limiting role under various working conditions. The valve body 1 is provided with a limit ring 15 corresponding to the limit groove 14, which improves stability. The limit ring 15 is an annular structure fixed to the valve body 1, and its position precisely corresponds to the limit groove 14 on the pilot head 11. When the pilot head 11 moves, the limit groove 14 interacts with the limit ring 15 to limit the range of the pilot head 11.

[0045] The contact piece 13 is inserted into the terminal 3 to achieve overall assembly. During the assembly process of the new two-way valve, the design of the contact piece 13 is also optimized. The contact piece 13 is a key component for providing electrical connection and is usually made of a material with excellent conductivity and corrosion resistance. In the new design, the contact piece 13 is designed to be inserted into the terminal 3. This connection method has multiple advantages. First, the plug-in design makes the installation process of the contact piece 13 simpler and faster. The connection can be completed by simply inserting the contact piece 13 into the terminal 3, which greatly improves the assembly efficiency. Secondly, the plug-in connection method ensures close contact between the contact piece 13 and the terminal 3, reduces contact resistance, and improves the reliability of the electrical connection.

[0046] Through the above-mentioned design optimization, the new two-way valve of this application realizes overall assembly. Overall assembly not only improves production efficiency, but also ensures the precise fit between the various components and the stability of the overall performance. In actual application, the new two-way valve has demonstrated significant advantages. The simplified assembly process greatly improves production efficiency and reduces production costs. The reliable connection method ensures the stability and safety of the two-way valve in long-term use. The optimized structural design makes the new two-way valve more convenient in installation, maintenance, etc., and improves the user experience.
