Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, and in particular to a gate valve that can be driven electrically or manually. Background Technology

[0002] Gate valves are widely used in outdoor gas pipelines due to their advantages such as low cost, small size, easy maintenance and convenient installation. Currently, most gate valves used in gas pipelines are purely electric switching valves. With prolonged use, there is a possibility of insufficient power supply and motor damage. Once a gas leak occurs, the valve cannot be closed immediately by the motor, which will cause incalculable losses.

[0003] Therefore, it is necessary to develop a shut-off valve that can be driven both electrically and manually to solve the above problems. Utility Model Content

[0036] like Figure 1 As shown, a shut-off valve that can be both electrically and manually driven includes:

[0037] Shut-off valve body 1;

[0038] Battery compartment 2;

[0039] Electric drive mechanism 3; battery compartment 2 is used to power electric drive mechanism 3;

[0040] Manual drive mechanism 4;

[0041] Manual clutch device 5; Manual clutch device 5 is used to connect to the output end of manual drive mechanism 4 or the output end of electric drive mechanism 3 respectively;

[0042] Lifting mechanism 6; manual clutch device 5 is connected to lifting mechanism 6 via transmission; the output end of lifting mechanism 6 is connected to valve stem 13 of shut-off valve body 1;

[0043] The drive mechanism frame 7; battery compartment 2, electric drive mechanism 3, manual drive mechanism 4, manual clutch device 5, and lifting mechanism 6 are all installed on the drive mechanism frame 7.

The valve cover 12 covers the top of the valve body 11. The lower end of the valve stem 13 is connected to the pressure relief block 15. The valve core 14 is formed into an annular shape and has a pressure relief hole. The pressure relief block 15 passes through the valve core 14 and is fitted with the upper part of the pressure relief block 15 to seal the pressure relief hole. The lower part of the pressure relief block 15 is formed into a convex annular shape. The pressure relief spring 16 is fitted onto the pressure relief block 15, and the two ends of the pressure relief spring 16 are connected to the top of the convex annular shape and the lower end of the valve core 14, respectively. When opening the valve, the valve stem 13 moves upward to overcome the spring force of the pressure relief spring 16 at the upper end of the pressure relief block 15, separating the pressure relief block 15 from the valve core 14 and opening the pressure relief hole. After pressure relief is completed, the valve core 14 continues to be pulled upward to separate from the vent hole inside the valve body 11, opening the valve. When closing the valve, the valve stem 13 moves downward, causing the valve core 14 to press down on the vent hole inside the valve, and then the pressure relief block 15 is reset to close the pressure relief hole. The shut-off valve body 1 is existing technology, and its structure and working principle will not be described in detail here.

[0046] In some embodiments, such as Figure 3 As shown, the electric drive mechanism 3 includes a geared motor 31 and a motor gear 32, with the output shaft of the geared motor 31 connected to the motor gear 32.

[0047] In some embodiments, such as Figure 3 and 4As shown, the manual clutch device 5 includes a clutch gear 52, a reversing lever 53, a lever return spring 54, a gear cover plate 55, a lever baffle 56, a lever part 57, and a positioning rod 58. An installation gap is provided between the lever baffle 56 and the drive mechanism frame 7. The second gear 433, the clutch gear 52, and the motor gear 32 are placed within the installation gap, with the clutch gear 52 positioned between the second gear 433 and the motor gear 32. The lever baffle 56 is installed on the outside of the gear cover plate 55. The lever baffle 56 and the gear cover plate 55 have overlapping first guide grooves 8. The lever part 57 is slidably disposed through the first guide groove 8. The first end of the reversing lever 53 is aligned with the lever part... The first end of rod 57 is connected to the first end of positioning rod 58. Clutch gear 52 and lifting rod return spring 54 are rotatably mounted on rod 57. The two ends of lifting rod return spring 54 contact one side of clutch gear 52 and the inner side of lifting rod baffle 56, respectively. The drive mechanism frame 7 is provided with a first positioning hole 71 and a second positioning hole 72. When rod 57 slides to the top of first guide groove 8, positioning rod 58 is inserted into second positioning hole 72, and clutch gear 52 meshes with second gear 433. When rod 57 slides to the bottom of first guide groove 8, positioning rod 58 is inserted into first positioning hole 71, and clutch gear 52 meshes with motor gear 32.

[0048] In some embodiments, such as Figure 3 and 4 As shown in Figure 5, the lifting mechanism 6 includes a second gear set 61, a rack 62, and a clutch bracket 51. The second gear set 61 includes a second rotating shaft 611, a third gear 612, and a fourth gear 613. The first ends of the third gear 612, the fourth gear 613, and the clutch bracket 51 are respectively mounted on the second rotating shaft 611. The second end of the clutch bracket 51 is mounted on a rod 57, which is parallel to the second rotating shaft 611. The third gear 612 meshes with the clutch gear 52, and the fourth gear 613 meshes with the rack 62. The lower end of the rack 62 is connected to the upper end of the valve stem 13.

[0049] In some embodiments, such as Figure 4 As shown, the lifting mechanism 6 also includes a third rotating shaft 63 and a guide wheel 64. The first end of the third rotating shaft 63 is connected to the guide wheel 64, and the second end of the third rotating shaft 63 is rotatably mounted on the drive mechanism frame 7. A second guide groove 65 is provided on the back of the rack 62, and the guide wheel 64 slides in a guide-sliding engagement with the second guide groove 65.

[0050] In some embodiments, such as Figure 6 As shown, the drive mechanism frame 7 includes a first vertical plate 73 and a second vertical plate 74 arranged in parallel with each other. The first vertical plate 73 is placed between the second vertical plate 74 and the gear cover plate 55. The second end of the third rotating shaft 63 is rotatably mounted on the second vertical plate 74.

[0051] Under normal use, the shut-off valve is generally driven by electricity. The clutch gear 52 is in the position of meshing with the motor gear 32. When the valve is opened, the battery compartment 2 provides voltage to the reduction motor 31, and the motor teeth rotate forward. The speed reduction transmission is transmitted to the rack 62 through the clutch gear 52 and the second gear set 61. The rack 62 drives the valve stem 13 to move upward. When the valve is closed, the motor reverses, and the process is the same. The rack 62 drives the valve stem 13 to move downward.

[0052] In case of an emergency requiring manual operation, first manually lift the reversing lever 53, disengaging the positioning rod 58 from the first positioning hole 71. Then, push the reversing lever 53 up along the first guide groove 8 to the top, and release the reversing lever 53. Under the action of the lever return spring 54, the positioning rod 58 inserts into the second positioning hole 72. At this time, the second gear 433 meshes with the clutch gear 52, while the meshing transmission between the clutch gear 52 and the third gear 612 remains unchanged. Then, rotate the hand crank 41 clockwise, which transmits the power to the rack 62 through the worm gear and a series of gears. The rack 62 drives the valve stem 13 downward to close the valve. To manually open the valve, rotate the hand crank 41 counterclockwise. Through transmission, the rack 62 drives the valve stem 13 upward to open the valve.

[0053] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
