[0002] When the pressure difference between the front and rear of the pipeline is large, it is often necessary to add a throttling ring plate. Its function is to reduce the aperture at the appropriate place of the pipeline. When the liquid passes through the constriction, the flow will become thinner or contract, so that the pressure of the fluid is reduced to throttle. In the process of using the throttling ring, in order to avoid repeated replacement and meet the various needs of users, it is very necessary to use an automatic adjustment device to adjust the throttling aperture of the throttling ring plate.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0022] The utility model embodiment provides a throttle ring automatic adjustment device, such as Figure 1-4 As shown, the throttle ring automatic adjustment device includes a mounting flange 1, a throttle ring plate 2 and a baffle 4, one side of the mounting flange 1 is connected to the throttle ring plate 2, and the baffle 4 is inserted inside the top of the throttle ring plate 2, a sealing ring 3 is arranged on the inner wall of the top of the throttle ring plate 2, the top of the baffle 4 is connected to a connecting rod 13, and the top of the connecting rod 13 is provided with a split structure 8, the top of the split structure 8 is provided with a moving block 11, and a guide rod 12 is inserted inside one side of the moving block 11, and the other side of the moving block 11 The internal thread is connected with a screw rod 7, and both ends of the screw rod 7 are connected with a support frame 9, the top of the support frame 9 is connected with a hand wheel 10, the outer side of the support frame 9 is provided with a dustproof structure 6, and the bottom end of the dustproof structure 6 is provided with a fixed plate 5, the split structure 8 includes a spring 801, a sleeve block 802, a connecting seat 803, a handle 804, an insert block 805, a magnet block 806 and a fixed block 807, the fixed block 807 is connected to the top of the connecting rod 13, and the outer side of the fixed block 807 is sleeved with a sleeve block 802.
[0023] The working principle of the throttling ring automatic adjustment device is: the throttling ring plate 2 is installed and fixed at the two ends of the two groups of pipes through the mounting flanges 1 on both sides, so that the liquid in the pipe passes through the aperture on the throttling ring plate 2 to become thinner or shrink, thereby achieving the throttling effect, and then the hand wheel 10 is used to rotate the screw 7 in the support frame 9 in the forward or reverse direction, so that the moving block 11 is threadedly engaged with the screw 7 and slides up and down along the surface of the guide rod 12, and then the connecting rod 13 drives the baffle 4 to gradually separate or overlap the aperture on the throttling ring plate 2 as the moving block 11 moves, thereby playing the role of adjusting the aperture on the throttling ring plate 2 through the operation of the size, which is convenient to meet a variety of needs. Compared with the traditional direct disassembly and replacement of the throttling ring plate 2 with the corresponding aperture size, it is more flexible and convenient. At the same time, the setting of the sealing ring 3 can prevent liquid from seeping out from above.
[0024] It should be noted that since the baffle 4 on the existing throttling ring automatic adjustment device is generally fixedly connected to the moving block 11 through the connecting rod 13 by bolts, it is not convenient to disassemble it when the screw 7, the moving block 11 and the guide rod 12 are worn. Therefore, in order to solve the problem that the existing throttling ring automatic adjustment device cannot be quickly disassembled, this solution adds a disassembly structure 8 to facilitate the rapid disassembly of the baffle 4 with the connecting rod 13 and the moving block 11.
[0025] In a further embodiment, Figure 1 and Figure 4 As shown, springs 801 are provided inside both sides of the sleeve block 802, and one side of the spring 801 is connected to a connecting seat 803, the bottom end of the connecting seat 803 is connected to a pull handle 804, one side of the connecting seat 803 is connected to an insert block 805, and the insides of both sides of the fixed block 807 are inlaid with magnet blocks 806, the insert block 805 extends to the inside of the fixed block 807 and contacts with the magnet block 806, the material of the insert block 805 is iron, the two ends of the moving block 11 are connected to the support frame 9, the hand wheel 10 is connected to the screw 7 through the bearing in the support frame 9, the fixed plate 5 and the throttling ring plate 2 are integrated, and the insert block 805 forms a telescopic structure with the spring 801 through the connecting seat 803.
[0026] In this embodiment, when it is necessary to separate the baffle plate 4 from the moving block 11, the two sets of pull handles 804 are supported by hand to drive the two sets of connecting seats 803 to compress the spring 801 to drive the two sets of plug blocks 805 to separate from the magnetic block 806, and completely leave the interior of the fixed block 807 to stop, and then the connecting rod 13 on the baffle plate 4 is pulled down to leave the interior of the sleeve block 802 for disassembly, thereby achieving the effect of separating the baffle plate 4 from the moving block 11, and then the bolts on the support frame 9 can be removed to remove the support frame 9 together with the worn moving block 11, guide rod 12 and screw 7 for replacement, so as to ensure the effect of the device. After the support frame 9 is fixed again with bolts, the two sets of pull handles 804 are pushed again to drive the connecting seat 803 to compress the spring 801 and drive the plug block 805 to enter the sleeve block 802, and then the connecting rod 13 is moved up and inserted into the sleeve block 802. The pull handle 804 is then released to allow the spring 801 to rebound and push the connecting seat 803 to drive the plug block 805 to be inserted into the fixed block 807 and contact and tighten with the magnet block 806 to fix the fixed block 807 in the sleeve block 802 under the replaced moving block 11, thereby achieving the effect of connecting the baffle 4 with the replaced moving block 11 through the connecting rod 13, thereby ensuring the stability of the baffle 4.
[0027] In a further embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the dustproof structure 6 includes a fixing frame 601, a turning handle 602, a fixing pin 603, a connecting block 604 and a dust cover 605.

The internal thread of the fixing frame 601 is connected with the fixing pin 603, and one side of the fixing pin 603 is connected to the turning handle 602. The other side of the fixing pin 603 is sleeved with a connecting block 604, and one side of the connecting block 604 is fixed with a dust cover 605. The connecting blocks 604 are symmetrically distributed on both sides of the dust cover 605, and the fixing pin 603 passes through the fixing frame 601 and is inserted into the interior of the connecting block 604.
[0028] In this embodiment, when it is necessary to cover the support frame 9 and the components inside it for dust prevention, the dust cover 605 is moved and put on the surface of the support frame 9 and is in contact with the fixed plate 5 for placement and support, thereby covering the support frame 9 and the components inside it for dust prevention, preventing dust from falling on the surfaces of the screw 7, the moving block 11 and the guide rod 12 in the support frame 9 to affect the movement effect. Then, the two sets of fixing pins 603 are rotated in opposite directions in sequence through the two sets of turning handles 602, so that the fixing pins 603 are threadedly engaged with the fixing frame 601 and gradually inserted into the connecting block 604, thereby fixing the dust cover 605 and ensuring the stability of the dust cover 605. The setting of the holes on the dust cover 605 facilitates the alignment of the hand wheel 10 through the exposed surface for use.
