[0004] In the above patent, although the oil valve improves the stability of the connection between the pipeline and the valve body, when the valve is opened and closed, in order to avoid the valve core opening and closing too quickly and causing the valve to be damaged by the impact of the fluid, the valve needs to be turned multiple times to complete the opening and closing. However, when the flow rate in the pipeline is slow or not in use, it takes a long time to operate the valve, which is time-consuming and affects work efficiency. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that when the valve is opened and closed, in order to avoid the valve core opening and closing speed being too fast and causing the valve to be damaged by the impact of the fluid, the valve needs to be turned multiple times to complete the opening and closing. However, when the flow rate in the pipeline is slow or the valve is not in use, it takes a long time to operate the valve, which is time-consuming and affects the work efficiency. A speed-adjustable petroleum valve is proposed.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the oil valve is in use and the oil pipeline is not in use for opening and closing operations, since there is no need to consider the speed of the valve core movement, turning the crank can drive the gear ring to follow the rotation.

Since the number of teeth on the gear ring and the second gear is more than that of the first gear, it can play a role in speeding up when driving the first gear to rotate. Therefore, it is only necessary to turn the crank a few times to drive the valve core to adjust to the right position, thereby achieving the purpose of adjusting the opening and closing speed of the valve core, saving time when adjusting the oil valve, and improving work efficiency.

[0015] 2. In the utility model, when the petroleum valve is in a fixed state of use, the hand-tightening bolt can be screwed and fixed inside the threaded hole, so that the hand-tightening bolt and the sleeve are fixed. At this time, the position of the adjusting rod can be limited and fixed by using the hand-tightening bolt, so as to avoid the adjustment rod rotating during the petroleum valve operation and affecting the valve core position, thereby improving the stability of the petroleum valve.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a speed-adjustable petroleum valve, comprising: a valve body 1, both side end surfaces of the valve body 1 are fixedly connected with flanges 2, an adjusting rod 3 is arranged inside the valve body 1, a rotating disk 4 is fixedly connected with the upper end surface of the adjusting rod 3, and a first gear 5 is fixedly connected with the outer surface of the adjusting rod 3; a speed regulating assembly 6, the speed regulating assembly 6 is fixedly connected to the outer surface of the valve body 1, the speed regulating assembly 6 comprises a sleeve 601, a support plate 602 is fixedly connected with the inner surface of the sleeve 601, a support shaft 604 is rotatably connected with the top of the support plate 602, a second gear 605 is fixedly connected with the upper end surface of the support shaft 604, and a speed regulating assembly 601 is fixedly connected to the outer surface of the valve body 1. There is an avoidance hole 603, which matches the position of the adjustment rod 3. The second gear 605 is flush with the first gear 5, and the second gear 605 is meshingly connected with the first gear 5. A groove 606 is opened on the top of the support plate 602, and a plurality of rollers 607 are evenly slidably connected to the inner surface of the groove 606. A connecting rod 608 is rotatably connected to the top of the roller 607. A gear ring 609 is fixedly connected between the upper end surfaces of the plurality of connecting rods 608. An extension rod 610 is fixedly connected to the top of the gear ring 609. A crank 611 is fixedly connected to the upper end surface of the extension rod 610. The gear ring 609 is meshingly connected with the second gear 605.

[0024] The effect achieved by the entire embodiment 1 is that when the oil valve is in use, the valve body 1 is connected to the oil pipeline through the flange 2. When the oil valve is opened and closed, the rotating disk 4 can drive the adjusting rod 3 to rotate, and the valve core inside the valve body 1 is driven to move by the rotating adjusting rod 3 to realize the opening and closing function. When the adjusting rod 3 is rotated to open and close the oil valve, the driving speed of the valve core by the rotating adjusting rod 3 is relatively slow, thereby avoiding damage to the oil valve caused by excessive flow velocity in the pipeline. When the oil pipeline is not in use and the opening and closing operation is performed, since there is no need to consider the moving speed of the valve core, the oil valve body 1 can be opened and closed. To solve the problem of degree, turning the crank handle 611 can drive the gear ring 609 to follow the rotation through the connection of the extension rod 610. When the gear ring 609 rotates, it can drive the first gear 5 to follow the rotation by engaging with the second gear 605. Since the number of teeth on the gear ring 609 and the second gear 605 is more than that of the first gear 5, it can play a role in speeding up when driving the first gear 5 to rotate. Therefore, it is only necessary to turn the crank handle 611 a few times to drive the valve core to adjust to the right position, thereby achieving the purpose of adjusting the opening and closing speed of the valve core, saving time when adjusting the oil valve, and improving work efficiency.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, a plurality of threaded holes 612 are evenly formed on the upper end surface of the sleeve 601, a through hole is formed on the top of the crank 611, a hand bolt 613 is inserted into the inner surface of the through hole, the threaded hole 612 matches the position of the through hole, and the outer surface of the hand bolt 613 is threadedly connected with the inner surface of the threaded hole 612.

[0026] The effect achieved by the entire embodiment 2 is that, when the oil valve is in a fixed use state, the hand-tightening bolt 613 is inserted from the through-hole position, and the hand-tightening bolt 613 can be screwed and fixed on the inner side of the threaded hole 612, so that the hand-tightening bolt 613 and the sleeve 601 are fixed. At this time, the position of the adjusting rod 3 can be limited and fixed by using the hand-tightening bolt 613, so as to avoid the adjusting rod 3 rotating during the oil valve process and affecting the valve core position, thereby improving the stability of the oil valve.

[0027] Working principle: When the oil valve is in use, the valve body 1 is connected to the oil pipeline through the flange 2. When the oil valve is opened and closed, the turntable 4 can drive the adjusting rod 3 to rotate, and the rotation of the adjusting rod 3 drives the valve core inside the valve body 1 to move to realize the opening and closing function. When the adjusting rod 3 is turned to open and close the oil valve, the pushing speed of the valve core due to the rotation of the adjusting rod 3 is slow, so as to avoid damage to the oil valve caused by excessive flow rate in the pipeline. When the oil pipeline is not in use for opening and closing operations, since there is no need to consider the problem of valve core movement speed, the crank handle 611 can drive the gear ring 609 to follow the rotation through the connection of the extension rod 610. When the gear ring 609 rotates, it can drive the first gear 5 to follow the rotation through the engagement with the second gear 605. The number of teeth of 609 and the second gear 605 are both greater than that of the first gear 5, so when driving the first gear 5 to rotate, it can play a role in speeding up. Therefore, it is only necessary to turn the crank 611 a few times to drive the valve core to adjust to the right position, thereby achieving the purpose of adjusting the opening and closing speed of the valve core. It saves time when adjusting the oil valve and improves work efficiency. When the oil valve is in a fixed use state, the hand-tightening bolt 613 is inserted from the through hole position, and the hand-tightening bolt 613 can be screwed and fixed on the inner side of the threaded hole 612, so that the hand-tightening bolt 613 and the sleeve 601 are fixed. At this time, the position of the adjusting rod 3 can be limited and fixed by using the hand-tightening bolt 613, so as to avoid the adjustment rod 3 rotating during the oil valve operation and affecting the valve core position, thereby improving the stability of the oil valve.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
