DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 6 , the utility model provides a technical solution:

[0028] Example 1:

[0029] An intelligent controlled fuel metering valve comprises a valve body 1, an intelligent controller 2 and a display screen 3. The intelligent controller 2 is fixedly mounted on the top of the valve body 1, and the display screen 3 is mounted on the top of the intelligent controller 2. The valve body 1 is characterized in that: connecting pipes 4 are provided on both sides of the valve body 1, a first docking ring 5 is fixedly connected to the surface of the connecting pipe 4, a second docking ring 6 is fixedly connected to both sides of the valve body 1, the top and bottom of the second docking block 8 are fixedly connected to a housing 7, the top and bottom of the first docking ring 5 are fixedly connected to a docking block 8, a clamping block 9 is fixedly connected to one side of the docking block 8, a clamping groove 10 for use with the clamping block 9 is provided on one side of the housing 7, a positioning mechanism is provided inside the clamping block 9, and a sealing mechanism is provided on one side of the connecting pipe 4;

[0030] The positioning mechanism includes a linkage block 11 arranged inside the shell 7. The linkage block 11 is fixedly connected to two connecting blocks 12 on one side close to the second docking ring 6. A transmission rod 13 is fixedly connected to one side of the connecting block 12. A transmission block 14 is sleeved on the surface of the transmission rod 13. The transmission block 14 is fixedly connected to a positioning block 15 on one side close to the second docking ring 6. The positioning block 15 is fixedly connected to a positioning rod 16 on one side close to the clamping block 9. One end of the positioning rod 16 passes through the interior of the shell 7. Positioning holes 17 for use with the positioning rod 16 are provided on both sides of the docking block 8.

[0031] In this embodiment, it is considered that when the intelligent controlled fuel metering valve is in use, the connecting pipe 4 needs to be connected to the valve body 1. However, the existing connection method mostly uses bolts, which is cumbersome to install, wastes the user's time and energy, and thus reduces the practicality of the intelligent controlled fuel metering valve. Therefore, by providing a positioning mechanism, the pressing block 28 can be pushed toward the side close to the second docking ring 6, and the pressing block 28 can drive the pressing rod 27, the linkage block 11, the connecting block 12, and the transmission rod 13 to move. As the transmission rod 13 moves, its surface will squeeze the beveled portion of the inner wall of the transmission block 14, thereby driving the transmission block 14 and the positioning block 15 to move along the trajectory of the sliding block 24 and the sliding groove 25 toward the side close to the spring 26. The positioning block 15 will drive the positioning rod 16 to leave the slot 10, and then align the position of the block 9 and the slot 10, and move the connecting pipe 4 to the side close to the valve body 1, so that the block 9 enters the slot 10, and then release the pressing block 28. The elastic force generated by the spring 26 will push the positioning block 15 and the positioning rod 16 to move, so that the positioning rod 16 enters the positioning hole 17 on the block 9, and the installation between the connecting pipe 4 and the valve body 1 is completed;

[0032] The invention solves the problem that when the intelligent control fuel metering valve is used, the connecting pipe 4 needs to be connected to the valve body 1, and the existing connection method mostly uses bolts for connection, which is cumbersome to install, wastes the user's time and energy, and thus reduces the practicality of the intelligent control fuel metering valve.

[0033] A sliding block 24 is fixedly connected to one side of the positioning block 15 , and a sliding groove 25 for use with the sliding block 24 is formed on the inner wall of the housing 7 .

[0034] In this embodiment, by providing a sliding block 24 and a sliding groove 25, when the transmission rod 13 squeezes the inner wall of the transmission block 14, the limiting and positioning block 15 and the positioning rod 16 and other structures can move along the trajectory of the sliding block 24 and the sliding groove 25, while improving the smoothness of their movement process.

[0035] A spring 26 is fixedly connected to one side of the positioning block 15 , and one end of the spring 26 is fixedly connected to the inner wall of the housing 7 .

[0036] In this embodiment, a spring 26 is provided. When the pressing block 28 is released, the elastic force generated by the spring 26 pushes the positioning block 15 and the positioning rod 16 to move, thereby achieving a reset effect.

[0037] A pressing rod 27 is fixedly connected to the side of the linkage block 11 away from the second docking ring 6 . One end of the pressing rod 27 passes through the outside of the housing 7 and is fixedly connected to a pressing block 28 .

[0038] In this embodiment, by providing a pressing rod 27 and a pressing block 28, the pressing rod 27, the linkage block 11, the connecting block 12 and the transmission rod 13 can be driven to move by pushing the pressing block 28, thereby facilitating driving.

[0039] Example 2:

[0040] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 ;

[0041] On the basis of Example 1, the positioning mechanism in this embodiment can facilitate the installation of the valve body 1 on the connecting pipe 4, but cannot guarantee the sealing after installation. The sealing mechanism in this application includes a butt joint 18 fixedly connected to one side of the connecting pipe 4, and a plurality of rubber sealing rings 19 are sleeved on the surface of the butt joint 18. Four embedded rods 20 are fixedly connected to one side of the rubber sealing ring 19, and an embedded hole 21 for use with the embedded rod 20 is opened on the other side of the rubber sealing ring 19.

[0042] In this embodiment, the positioning mechanism facilitates the installation of the valve body 1 and the connecting pipe 4, but cannot guarantee a tight seal after installation. Therefore, a sealing mechanism is provided. As the connecting pipe 4 and the valve body 1 are pushed into contact, the connecting pipe 18 enters the interior of the valve body 1. Simultaneously, multiple rubber sealing rings 19 ensure a tight seal during the connection process, preventing leakage. The multiple rubber sealing rings 19 are connected by an embedded rod 20 and an embedded opening. Even if one of the rubber sealing rings wears, the sealing of the connection is ensured.

[0043] The problem that the positioning mechanism can facilitate the installation of the valve body 1 and the connecting pipe 4 but cannot ensure the sealing after installation is solved.

[0044] A retaining ring 22 is fixedly connected to the inner wall of the valve body 1 and is opposite to the rubber sealing ring 19 . A buffer pad 23 is fixedly connected to one side of the retaining ring 22 .

[0045] In this embodiment, by providing a retaining ring 22 and a buffer pad 23, when the docking pipe 18 enters the valve body 1, the rubber sealing ring 19 close to the retaining ring 22 will contact the buffer pad 23, thereby improving the tightness between the multiple rubber sealing rings 19 and further improving the sealing effect.

[0046] One end of the embedded rod 20 is spherical.

[0047] In this embodiment, by setting one end of the embedding rod 20 to be spherical, the stability of the installation between the two rubber sealing rings 19 can be improved after the embedding rod 20 enters the embedding groove.

[0048] Working principle: The user pushes the pressing block 28 toward the side close to the second docking ring 6, and the pressing block 28 drives the pressing rod 27, the linkage block 11, the connecting block 12 and the transmission rod 13 to move. While the transmission rod 13 moves, its surface will squeeze the beveled portion of the inner wall of the transmission block 14, thereby driving the transmission block 14 and the positioning block 15 to move along the trajectory of the sliding block 24 and the sliding groove 25 toward the side close to the spring 26. The positioning block 15 will drive the positioning rod 16 to leave the inside of the card slot 10, and then align the positions of the card block 9 and the card slot 10, and move the connecting pipe 4 toward the side close to the valve body 1, so that the card block 9 enters the inside of the card slot 10, and then release the pressing block 28. The elastic force generated by the spring 26 will push the positioning block 15 and the positioning rod 16 to move, so that the positioning rod 16 enters the inside of the positioning hole 17 on the card block 9, completing the installation between the connecting pipe 4 and the valve body 1;

[0049] As the connecting tube 4 is pushed into contact with the valve body 1, the connecting tube 18 enters the interior of the valve body 1. Multiple rubber sealing rings 19 ensure a tight seal during the connection process, preventing leakage. These rubber sealing rings 19 are connected by embedded rods 20 and embedded openings, ensuring a tight seal even if one of them wears.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
