[0022] Reference Figures 1 to 6In this embodiment of the utility model, a directional control valve with variable function includes: a main valve body 1 and a solenoid valve 2. The main valve body 1 is the main structure of the directional control valve, providing a mounting base for other components and serving as the main location for oil flow and directional control. The solenoid valve 2 controls the movement of the valve core by changing the energization state of the electromagnet, thereby changing the function of the directional control valve. A connecting pipe 3 is fixedly connected to one end of the side wall of the main valve body 1, connecting the main valve body 1 and the solenoid valve 2, providing a channel for oil to flow between the two. A controller 4 is fixedly connected to one end of the top of the main valve body 1, and a flow sensor 5 is fixedly connected to one end of the connecting pipe 3. The controller 4 receives data from the flow sensor 5 and sends a control signal to the solenoid valve 2 according to a preset program to regulate the operation of the reversing valve. The flow sensor 5 monitors the fluid flow rate through the connecting pipe 3 in real time and transmits the data to the controller 4. A disassembly and assembly mechanism 6 is provided between the connecting pipe 3 and the solenoid valve 2 to enable quick disassembly and assembly of the connecting pipe 3 and the solenoid valve 2, facilitating maintenance and replacement. The solenoid valve 2, the controller 4, and the flow sensor 5 are electrically connected. There are multiple sets of connecting pipes 3 located symmetrically at multiple ends on the side wall of the main valve body 1.

[0023] Reference Figures 1 to 4 The solenoid valve 2 has a sealing groove 7 at one end, and a sealing gasket 8 is fixedly connected to the other end of the connecting pipe 3. The gasket 8 is embedded in the sealing groove 7 to enhance the sealing performance of the connection. The sealing gasket 8 and the sealing groove 7 are compatible. A mounting block 9 is fixedly connected to the lower outer side of the main valve body 1. It is fixed to the lower outer side of the main valve body 1 and is used to install the entire directional valve. A mounting hole 10 is opened in the middle of the mounting block 9.

[0024] Reference Figure 1 , Figure 5 and Figure 6The disassembly and assembly mechanism 6 includes a fixed support plate 601, a fixed connecting plate 602, and a locking ring cover 603. The fixed support plate 601 is fixedly connected to one end of the connecting pipe 3, the fixed connecting plate 602 is fixedly connected to one end of the solenoid valve 2, and the locking ring cover 603 is rotatably connected to the outside of the fixed connecting plate 602. It also includes an annular cavity 604, a spring 605, a moving ring 606, and a sliding locking ring 607. The annular cavity 604 is located at one end of its front side, the spring 605 is fixedly connected to one end of the annular cavity 604, the moving ring 606 is inserted into the inside of the annular cavity 604, and the sliding locking ring 607 is fixedly connected to the outside of the moving ring 606. Furthermore, it includes a magnetic positioning pin 608, a positioning pin groove 609, and a handle 610. The magnetic positioning pin 608 is fixedly connected to one end of the moving ring 606, the positioning pin groove 609 is located at one end of the fixed connecting plate 602, and the handle 610 is fixedly connected to one end of the sliding locking ring 607. The spring... The other end of 605 is fixedly connected to the moving ring 606. The sliding locking ring 607 is inserted into the fixed support plate 601. The locking ring cover 603 is threadedly connected to the sliding locking ring 607. The magnetic positioning pin 608 and the positioning pin groove 609 are matched. There are four sets of magnetic positioning pins 608 and positioning pin grooves 609. Hold the handle 610 to move the sliding locking ring 607 and the moving ring 606 toward the fixed support plate 601 and fix them. Align the sealing gasket 8 of the connecting pipe 3 with the sealing groove 7 of the solenoid valve 2. The position is initially aligned. The relative position of the fixed support plate 601 and the fixed connecting plate 602 is determined. The magnetic positioning pin 608 is partially inserted into the positioning pin groove 609 to complete the initial fixation limit. Rotate the locking ring cover 603 to connect with the sliding locking ring 607, which drives the fixed connecting plate 602 and the solenoid valve 2 to move toward the fixed support plate 601 until the threads of both are fully locked. The disassembly and assembly mechanism 6 is fixed. The solenoid valve 2 is sealed to the connecting pipe 3.

[0025] The working principle of this utility model is as follows: When installing the solenoid valve 2, first, grip the handle 610 to control the sliding locking ring 607 and the moving ring 606 to move and fix them towards the fixed support plate 601. Then, align the sealing gasket 8 on the connecting pipe 3 with the sealing groove 7 at one end of the solenoid valve 2 to initially align their positions. At the same time, the relative positions of the fixed support plate 601 and the fixed connecting plate 602 are also initially determined. At this time, the magnetic positioning pin 608 is partially inserted into the positioning pin groove 609 to achieve initial fixation and limitation. Next, rotate the locking ring cover 603 to connect it with the fixed sliding locking ring 607. During the rotation, rotating the locking ring cover 603 will drive the fixed connecting plate 602 and the solenoid valve 2 to move together towards the fixed support plate 601 until the rotating locking ring cover 603 and the sliding locking ring 607 are completely locked by threads. At this point, all components in the disassembly and assembly mechanism 6 are firmly fixed, and the solenoid valve 2 and the connecting pipe 3 are sealed. The sealing connection is achieved through the design of the spring 605 and the connection between the fixed support plate 601 and the sliding locking ring 607, and the moving ring 606 and the annular cavity 604. After fixing, a certain space is reserved to facilitate subsequent disassembly. At the same time, the sealing groove 7 and the sealing gasket 8 have a certain length, and the reserved space will not affect their sealing performance. In this way, the entire installation and disassembly process can be completed quickly without the aid of other tools. The operation is simple and practical, which greatly facilitates the maintenance and replacement of the main valve body 1 and the solenoid valve 2 in daily use. During the operation of the reversing valve, the flow sensor 5 monitors the fluid flow through the connecting pipe 3 in real time and transmits the data to the controller 4. The controller 4 sends a control signal to the solenoid valve 2 according to the preset program and the received flow data. By changing the energization state of the electromagnet, the controller controls the movement of the valve core inside the solenoid valve 2, thereby realizing the change of the reversing valve function to meet different working conditions and fluid control requirements.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
