Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic cylinder mounting structure, specifically to an adjustment structure for mounting valve couplings. Background Technology

[0002] A valve coupling is a mechanical part that connects a valve drive device (such as a motor or handwheel) to the valve stem, serving to transmit power, compensate for deviations, and buffer and dampen vibrations.

[0003] Traditional methods for installing valve couplings involve rotating a fixed gear sleeve, pressing it down to prevent axial movement during adjustment, and then rotating the coupling to rotate the fixed gear sleeve until the coupling mates with the valve's hexagonal or keyed joint. Finally, a tapered sleeve is used to tighten the fixed gear sleeve. During operation, vibrations and high temperatures from the equipment can cause the coupling and its connected transmission structure to shift, leading to reduced transmission efficiency and worsening the angle of the connected transmission mechanism. Therefore, we propose an adjustment structure for installing valve couplings. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides an adjustment structure for installing valve couplings.

[0005] The technical solution adopted by this utility model to solve its technical problem is an adjustment structure for installing a valve coupling, including a connecting rod sleeve and a splicing flange. A coupling sleeve is integrally constructed on one side of the connecting rod sleeve, and a connecting flange is integrally constructed on the end of the coupling sleeve away from the connecting rod sleeve. Multiple equidistantly distributed adjusting screw sleeves are provided on the outer periphery of the coupling sleeve. An adjusting screw is screwed into the inside of the adjusting screw sleeve, and the adjusting screw passes through the side wall of the connecting flange.

[0006] The two side walls of the splicing flange are each integrally constructed with a fastening threaded sleeve. The fastening threaded sleeve is internally connected with a tightening bolt. One end of the tightening bolt passes through the fastening threaded sleeve and is rotatably connected to the inside of the rotating connecting seat. The end of the rotating connecting seat away from the tightening bolt is fixedly connected to the side wall of the coupling clamp arm. The splicing flange has a groove inside that matches the coupling clamp arm.

[0007] By adopting the above technical solution, when the coupling undergoes a certain angular displacement due to high temperature and vibration during operation, the adjusting screw is rotated through the connecting flange and the splicing flange to abut against the reference adjusting seat. The connection structure of the connecting rod sleeve, coupling sleeve and splicing flange is deflected with reference to the reference adjusting seat, so that it can be restored to a relatively perpendicular position by extending the splicing flange to abut against the reference adjusting seat. During installation, the angle between the connecting rod sleeve and coupling sleeve and the reference adjusting seat is quickly calibrated by abutting the splicing flange against the reference adjusting seat, and can be adjusted to a perpendicular state by rotating the adjusting screw.

[0008] During installation, the adjustment structure is first installed by fitting the splicing flange, then the connecting rod sleeve and the coupling sleeve. After moving it to the appropriate position, the rotating connecting seat is pushed by rotating the loosening bolt, and the coupling clamp arm moves toward the coupling under the restriction of the sliding rod, thereby clamping and locking the coupling. Then, the adjusting screw is screwed in to install the connecting rod sleeve and the coupling sleeve onto the side wall of the splicing flange, thus completing the installation.

[0009] Specifically, a reference adjustment seat for calibration is provided at the end of the splicing flange away from the linkage sleeve.

[0010] By adopting the above technical solution, a reference adjustment seat, which is the same as the connecting rod sleeve, coupling sleeve and splicing flange but without the adjustment screw and its related structures, is fitted on the outer periphery of one end of the transmission equipment to facilitate the adjustment screw to drive the connecting rod sleeve for offset calibration.

[0011] Specifically, the surface of the splicing flange is provided with splicing screw holes that match the adjusting screw.

[0012] By adopting the above technical solution, the adjusting screw passes through the splicing screw hole to abut against the reference adjusting seat at the other end, and the offset angle is adjusted based on it.

[0013] Specifically, the rotating connecting seat has integrated sliding rods on both sides for limiting the position, and the splicing flange has a sliding groove inside that matches the sliding rods.

[0014] By adopting the above technical solution, the rotation direction of the coupling clamp arm is limited by the sliding of the slide rod inside the splicing flange, so that it can only slide horizontally inside the splicing flange as the tightening bolts rotate.

[0015] Specifically, the end of the connecting rod sleeve away from the coupling sleeve has a through-hole for the connecting rod to pass through the coupling shaft.

[0016] By adopting the above technical solution, the device is sleeved on the outer periphery of the transmission rod through the linkage rod insertion hole, so that it can slide towards or away from the coupling along the linkage rod. After installation and locking, the angle of the coupling can be adjusted by adjusting the adjusting screw.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the coupling undergoes a certain angular displacement due to high temperature and vibration during operation, the adjusting screw is rotated through the connecting flange and the splicing flange to abut against the reference adjusting seat. The connection structure of the connecting rod sleeve, coupling sleeve and splicing flange is deflected with reference to the reference adjusting seat, so that it can be restored to a relatively perpendicular position by extending the splicing flange to abut against the reference adjusting seat. During installation, the angle between the connecting rod sleeve and coupling sleeve and the reference adjusting seat is quickly calibrated by abutting the splicing flange against the reference adjusting seat, and can be adjusted to a perpendicular state by rotating the adjusting screw.

[0019] 2. During installation, first install the adjusting structure by fitting the splicing flange, then the connecting rod sleeve and the coupling sleeve. After moving it to the appropriate position, rotate the loosening bolt to push the rotating connecting seat and, under the restriction of the sliding rod, move the coupling clamp arm toward the coupling to clamp and lock the coupling. Then, screw in the adjusting screw to install the connecting rod sleeve and the coupling sleeve onto the side wall of the splicing flange, thus completing the installation.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-3This utility model provides a technical solution: an adjustment structure for installing a valve coupling, including a connecting rod sleeve 1 and a splicing flange 7. One side of the connecting rod sleeve 1 is integrally constructed with a coupling sleeve 3, and the end of the coupling sleeve 3 away from the connecting rod sleeve 1 is integrally constructed with a connecting flange 4. Multiple equidistantly distributed adjusting screw sleeves 5 are provided on the outer periphery of the coupling sleeve 3. An adjusting screw 6 is screwed into the inside of the adjusting screw sleeve 5, and the adjusting screw 6 passes through the side wall of the connecting flange 4.

[0027] The two side walls of the splicing flange 7 are integrally constructed with fastening threaded sleeves 8. The fastening threaded sleeves 8 are internally connected with tightening bolts 9. One end of the tightening bolts 9 passes through the fastening threaded sleeves 8 and is rotatably connected to the inside of the rotating connecting seat 10. The end of the rotating connecting seat 10 away from the tightening bolts 9 is fixedly connected to the side wall of the coupling clamp arm 11. The splicing flange 7 has a groove inside that matches the coupling clamp arm 11.

[0028] During use, when the coupling experiences angular displacement due to high temperature and vibration during operation, the adjusting screw 6 is rotated through the connecting flange 4 and the splicing flange 7 to abut against the reference adjusting seat 14. This allows the connection structure of the connecting rod sleeve 1, coupling sleeve 3, and splicing flange 7 to be deflected with reference to the reference adjusting seat 14. This enables the coupling to be restored to a relatively perpendicular position by extending the splicing flange 7 to abut against the reference adjusting seat 14. During installation, the angle between the connecting rod sleeve 1 and coupling sleeve 3 and the reference adjusting seat 14 is quickly calibrated by abutting the splicing flange 7 against the reference adjusting seat 14, and can be adjusted until it reaches a perpendicular state by rotating the adjusting screw 6.

[0029] During installation, the adjustment structure is first installed by fitting the splicing flange 7, then the connecting rod sleeve 1 and the coupling sleeve 3. After moving it to the appropriate position, the rotating connecting seat 10 is pushed by rotating the loosening bolt 9, and the coupling clamp arm 11 moves toward the coupling under the restriction of the slide rod 12, thereby clamping and locking the coupling. Then, the adjusting screw 6 is screwed in to install the connecting rod sleeve 1 and the coupling sleeve 3 onto the side wall of the splicing flange 7, thus completing the installation.

[0030] As shown in the figure, a reference adjustment seat 14 for calibration is provided at the end of the splicing flange 7 away from the linkage sleeve 1.

[0031] In use, a reference adjustment seat 14, which is the same as the connecting rod sleeve 1, coupling sleeve 3 and splicing flange 7 but without the adjusting screw 6 and its related structures, is fitted around the outer periphery of one end of the transmission equipment to facilitate the adjustment screw 6 to drive the connecting rod sleeve 1 for offset calibration.

[0032] As shown in the figure, the surface of the splicing flange 7 is provided with splicing screw holes 13 that fit with the adjusting screw 6.

[0033] In use, the adjusting screw 6 passes through the splicing screw hole 13 to abut against the reference adjusting seat 14 at the other end, and the offset angle is adjusted based on it.

[0034] As shown in the figure, the rotating connecting seat 10 has an integral structure on both sides with sliding rods 12 for limiting the position, and the splicing flange 7 has a sliding groove inside that matches the sliding rods 12.

[0035] In use, the rotation direction of the coupling clamp arm 11 is limited by the sliding of the slide rod 12 inside the splicing flange 7, so that it can only slide horizontally inside the splicing flange 7 as the tightening bolt 9 rotates.

[0036] As shown in the figure, the end of the connecting rod sleeve 1 away from the coupling sleeve 3 is provided with a connecting rod insertion hole 2 for the connecting shaft to pass through.

[0037] In use, the device is fitted onto the outer circumference of the transmission rod through the linkage rod insertion hole 2, allowing it to slide towards or away from the coupling along the linkage rod. After installation and locking, the angle of the coupling is adjusted by adjusting the adjusting screw 6.

[0038] The working principle and usage process of this utility model are as follows: During installation, the adjusting structure is first installed by fitting the splicing flange 7, followed by the connecting rod sleeve 1 and the coupling sleeve 3. After moving it to the appropriate position, the rotating connecting seat 10 is pushed by rotating the loosening bolt 9, and under the restriction of the sliding rod 12, the coupling clamping arm 11 moves towards the coupling, thereby clamping and locking the coupling. Then, the adjusting screw 6 is screwed in to install the connecting rod sleeve 1 and the coupling sleeve 3 onto the side wall of the splicing flange 7, thus completing the installation. When the coupling deviates at a certain angle due to high temperature and vibration during operation... When moving, the adjusting screw 6 is rotated through the connecting flange 4 and the splicing flange 7 to abut against the reference adjusting seat 14. The connection structure of the connecting rod sleeve 1, the coupling sleeve 3 and the splicing flange 7 is deflected with reference to the reference adjusting seat 14, so that it can be restored to a relatively perpendicular position by extending the splicing flange 7 to abut against the reference adjusting seat 14. During the installation process, the angle between the positioning connecting rod sleeve 1 and the coupling sleeve 3 and the reference adjusting seat 14 is quickly calibrated by abutting the splicing flange 7 against the reference adjusting seat 14, and can be adjusted until it is in a vertical state by rotating the adjusting screw 6.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
