[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] Example 1: As Figure 1-5 As shown, this utility model provides an analog valve controller with port isolation function, including a valve 1. A main body mechanism 2 is provided on the top surface of the valve 1. A panel 3 is fixedly connected to one end of the top surface of the main body mechanism 2. A port 5 is fixedly connected to the input end of the main body mechanism 2. A latching mechanism 4 is provided on the bottom side of the main body mechanism 2. The latching mechanism 4 includes a fixed housing 41, which is fixedly connected to the bottom side of the main body mechanism 2. A locking tongue 42 is movably connected inside the fixed housing 41 and is movably connected to the inside of a fixing groove 62. A locking spring 43 is fixedly connected to the side of the locking tongue 42, and one end of the locking spring 43 is fixedly connected to the inside of the fixed housing 41. An isolation mechanism 6 is provided on the top side of the main body mechanism 2. The isolation mechanism 6 includes a metal isolation cover 61, which is movably connected to the top side of the main body mechanism 2. A support rod 64 is movably connected to the inner side of the metal isolation cover 61. A fixing device 63 is fixedly connected to the side of the support rod 64, and the fixing device 63 includes a fixing plate 631. A fixing plate 631 is fixedly connected to the side of support rod 64. A limiting plate 632 is fixedly connected to the side of the fixing plate 631. One end of the limiting plate 632 is movably connected to the side of support rod 66. A rotating rod 634 is fixedly connected to the side of the fixing plate 631. A connecting plate 633 is rotatably connected to the outer surface of the rotating rod 634. Support rod 66 is fixedly connected to the side of the connecting plate 633. A locking groove 636 is provided inside the side of the connecting plate 633. A locking block 635 is slidably connected inside the side of the rotating rod 634. The locking block 635 is slidably engaged inside the locking groove 636. A locking spring 637 is fixedly connected to the side of the locking block 635. One end of the locking spring 637 is fixedly connected to the inside of the rotating rod 634. The other end of the fixing device 63 is fixedly connected to the second support rod 66. A fixing buckle 67 is movably connected to the side of the second support rod 66. The fixing buckle 67 is fixedly connected to the side of the main body mechanism 2. A pull rod 65 is fixed to the top of the side of the metal isolation cover 61. A fixing groove 62 is opened at the bottom of the side of the metal isolation cover 61.

[0024] In this embodiment, the metal isolation cover 61 can reduce electromagnetic interference to a certain extent. The number of isolation mechanisms 6 is equal to the number of ports 5, and a certain gap is reserved between each isolation mechanism 6 so that they will not affect each other. The size of the locking tongue 42 is equal to that of the fixing groove 62. When the metal isolation cover 61 is in the closed state, the locking tongue 42 is pushed by the locking spring 43 and locked inside the fixing groove 62 to ensure the locked state of the metal isolation cover 61. At this time, the metal isolation cover 61 can protect the ports 5 and prevent liquid or dust from falling into the ports 5 and causing damage to the ports 5. When the corresponding port 5 needs to be used, the locking tongue 42 can be pressed so that the locking spring 43 will drive the locking tongue 42 to retract into the fixing shell 41. At this time, the pull rod 65 can be pushed to open the metal isolation cover 61. Since the fixing buckle 67 is fixed, Fixed to the side of the controller body 21, when the metal isolation cover 61 is opened, it will cause the second support rod 66 and the first support rod 64, which are in a folded state, to move. The movement of the second support rod 66 and the first support rod 64 will cause the fixing plate 631 and the connecting plate 633 to rotate around the rotating rod 634. At this time, the locking block 635, which is in a retracted state inside the rotating rod 634, will be pushed by the locking spring 637 and locked into the inside of the locking groove 636, so that the second support rod 66 and the first support rod 64 provide sufficient support for the metal isolation cover 61, ensuring that the metal isolation cover 61 is in the open state. The limiting plate 632 can prevent the second support rod 66 and the first support rod 64 from moving in the opposite direction. When it is necessary to close the metal isolation cover 61, simply press down the pull rod 65. At this time, the locking block 635 will retract back into the inside of the rotating rod 634 along the arc-shaped sliding groove set in the locking groove 636.

[0025] Example 2: Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the main body 2 includes a controller body 21, the controller body 21 is fixedly connected to the top surface of the valve 1, a hinge 22 is fixedly connected to the top side of the controller body 21, a metal isolation cover 61 is movably connected to the outer surface of the hinge 22, a fixing buckle 67 is fixedly connected to the bottom side of the controller body 21, and a fixing shell 41 is fixedly connected to the other side of the controller body 21.

[0026] The controller body 21 has a control panel 24 inside the top surface. The controller body 21 has a slide groove 23 on the inner side. A cover plate 25 is slidably connected inside the slide groove 23. A spring 26 is fixedly connected to one side end of the cover plate 25.

[0027] One end of the spring 26 is fixedly connected to the inside of the slide groove 23, and a rubber block 27 is fixedly connected to the bottom surface of the controller body 21. The rubber block 27 is engaged in a slot provided inside the controller body 21.

[0028] In this embodiment, valve 1 is fixed to the bottom surface of controller body 21, buckle mechanism 4 and port 5 are both fixed to the side of controller body 21, and panel 3 is fixed to the top surface of controller body 21 to display data. Controller body 21 can fix metal isolation cover 61 to the side of controller body 21 and allow it to move around controller body 21 as an axis. Under normal conditions, cover plate 25 can be pushed by spring 26 to cover control panel 24, preventing accidental touch from affecting the normal operation of controller body 21, and also providing a certain degree of protection for control panel 24. When control panel 24 needs to be used, cover plate 25 can be pulled by the handle on the top surface of cover plate 25. At this time, cover plate 25 slides along slide groove 23 to expose control panel 24. When cover plate 25 moves to its maximum stroke, rubber block 27 will engage inside controller body 21 to ensure that spring 26 does not affect the opening state of cover plate 25.

[0029] The working principle of this analog valve controller with port isolation function will be explained in detail below.

[0030] like Figure 1-5As shown, by fixing valve 1 in the desired position, the flow rate of valve 1 can be controlled by the controller body 21. When the metal isolation cover 61 is in the closed state, the locking tongue 42 is pushed by the locking spring 43 and locked inside the fixing groove 62, ensuring the metal isolation cover 61 is in the locked state. At this time, the metal isolation cover 61 can protect the port 5, preventing liquid or dust from falling into the port 5 and causing damage to the port 5. When the corresponding port 5 needs to be used, the locking tongue 42 can be pressed to engage the locking spring 43. 3 will cause the locking tongue 42 to retract into the fixed shell 41. At this time, the pull rod 65 can be pushed to open the metal isolation cover 61. Since the fixing buckle 67 is fixed to the side of the controller body 21, when the metal isolation cover 61 is opened, it will cause the second support rod 66 and the first support rod 64, which are in a folded state, to move. The movement of the second support rod 66 and the first support rod 64 will cause the fixed plate 631 and the connecting plate 633 to rotate around the rotating rod 634. At this time, the locking block 635, which is in a retracted state inside the rotating rod 634, will be locked by the locking spring 637. When pushed, the locking block 635 engages inside the locking groove 636, providing sufficient support for the metal isolation cover 61 by the second support rod 66 and the first support rod 64, ensuring that the metal isolation cover 61 is in the open state. The limiting plate 632 can prevent the second support rod 66 and the first support rod 64 from moving in the opposite direction. When it is necessary to close the metal isolation cover 61, simply press down on the pull rod 65. At this time, the locking block 635 will retract back into the rotating rod 634 along the arc-shaped sliding groove provided in the locking groove 636. Under normal conditions, the cover plate 25 can be pushed by the spring 26. The cover plate 24 serves to shield the control panel 24, preventing accidental touches from affecting the normal operation of the controller body 21, and also provides a certain degree of protection for the control panel 24. When the control panel 24 needs to be used, the cover plate 25 can be pulled by the handle on the top surface of the cover plate 25. At this time, the cover plate 25 slides along the slide groove 23, exposing the control panel 24. When the cover plate 25 moves to its maximum stroke, the rubber block 27 will engage inside the controller body 21, ensuring that the spring 26 will not affect the opening state of the cover plate 25.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all modifications or improvements made without departing from the spirit and concept of the present invention are within the protection scope of the present invention.
