Description

Technical Field

[0001] This utility model relates to the field of regulating device technology, specifically to a valve position regulating device with a locking structure. Background Technology

[0002] Valve position regulation mainly refers to controlling parameters such as flow rate, pressure, and temperature of fluids, such as gas and liquid, by adjusting the valve opening to meet the operational requirements of the process system.

[0003] Currently, in small systems, temporary debugging, or emergency operations, valve positions are usually changed directly by manually operating mechanical parts such as handwheels and handles. Although manual operation is highly flexible, the accuracy of adjustment is low, and it is not convenient to lock the adjusted valve position. The valve position is easily affected by external factors and may become misaligned, which can easily affect the adjustment effect of the valve position. Utility Model Content

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figures 1 to 4A valve position adjusting device with a locking structure includes a valve body 1, on which multiple valve stems 2 are mounted for easy valve position adjustment. It also includes a mounting plate 3, an active plate 4, a driven plate 5, a lifting plate 6, a lifting assembly, locking rods 7, and a locking frame 8. The mounting plate 3 is detachably connected to the valve body 1. The active plate 4 is rotatably mounted on the top of the mounting plate 3. A rotating seat is provided between the driven plate 5 and the active plate 4. The lifting plate 6 is raised and lowered above the active plate 4 and the driven plate 5. The lifting assembly is installed between the lifting plate 6, the active plate 4, and the driven plate 5. Two locking rods 7 are symmetrically connected to the top of the lifting plate 6. The locking frame 8 is fixedly connected to the top of each locking rod 7, and the locking frame 8 has locking grooves that match the valve stems 2. A frosted pad 20 is fixedly connected to each of the two locking grooves to limit and lock the corresponding two valve stems 2.

[0042] refer to Figure 3 as well as Figure 4 The lifting assembly includes a rotating handle 9, a threaded rod 10, a limiting rod 11, a limiting plate 12, and a limiting block 13. The rotating handle 9 is rotatably mounted on the active plate 4. The rotating handle 9 has multiple protrusions, which can be clamped and rotated with the help of external tools. The threaded rod 10 is fixedly connected to the top of the rotating handle 9 and is threadedly connected to the lifting plate 6. A retaining ring 19 is fixedly connected to the rotating handle 9. The active plate 4 has a retaining groove for the retaining ring 19 to rotate, which increases the stability of the rotating handle 9 rotating on the active plate 4. The limiting rod 11 is fixedly fixed to the top of the driven plate 5, and the lifting plate 6 has a limiting opening for the limiting rod 11 to slide. The limiting plate 12 is fixedly connected to the top of the threaded rod 10, which can limit the lifting of the lifting plate 6 on the threaded rod 10. The limiting block 13 is fixedly connected to the top of the limiting rod 11, which can limit the movement of the lifting plate 6 on the limiting rod 11.

[0043] When it is necessary to adjust the locking height of the two locking brackets 8, rotate the handle 9 so that the handle 9 drives the threaded rod 10 to rotate. At the same time, the lifting plate 6 will rise and fall through the rotation of the threaded rod 10. During the rising and falling of the lifting plate 6, the limit rod 11 will limit the rising and falling of the lifting plate 6 so that the lifting plate 6 drives the two locking rods 7 to rise and fall stably. This allows the height of the two locking brackets 8 to be adjusted, so that the two locking brackets 8 and the two frosted pads 20 limit and lock the corresponding two valve stems 2, reducing the misalignment deviation of the valve position caused by external influences.

[0044] refer to Figure 1 as well as Figure 3The rotating seat includes a rotating ring 14, a fixed plate 15, and a fixed cone 16. The rotating ring 14 is fixedly connected between the driving plate 4 and the driven plate 5, and the mounting plate 3 has a rotating groove for the rotating ring 14 to rotate. There are two fixed plates 15, which are symmetrically connected to the top of the rotating ring 14. There are two fixed cones 16, which are detachably connected between the fixed plate 15 and the mounting plate 3, and the mounting plate 3 has multiple fixing holes that match the fixed cones 16.

[0045] When the rotating ring 14 rotates in the rotating groove, it can drive the driving plate 4 and the driven plate 5 to rotate simultaneously on the mounting plate 3, so that the threaded rod 10 and the limit rod 11 can drive the lifting plate 6 to rotate. At the same time, the lifting plate 6 will drive the two locking rods 7 and the two locking frames 8 to rotate simultaneously, rotating the two locking frames 8 to the appropriate locking position, that is, the two locking frames 8 are respectively located directly below the two corresponding valve stems 2. After the rotating ring 14 rotates to the appropriate position, the two fixing cones 16 are respectively inserted into the two fixing holes, and the position of the rotating ring 14 can be fixed on the mounting plate 3, thereby fixing the positions of the driving plate 4, the driven plate 5, the threaded rod 10, the lifting plate 6, the locking rods 7 and the locking frames 8.

[0046] refer to Figure 1 as well as Figure 2 A mounting base is detachably provided between the mounting plate 3 and the valve body 1. The mounting base includes a mounting ring 17 and mounting screws 18. The mounting ring 17 is fixedly connected to the mounting plate 3. Multiple mounting screws 18 are arranged in a circumferential array between the mounting ring 17 and the valve body 1.

[0047] By rotating multiple mounting screws 18 between the mounting ring 17 and the valve body 1, the mounting ring 17 and the valve body 1 can be connected and disassembled, thereby allowing the mounting plate 3, the driving plate 4, the driven plate 5, the rotating handle 9, the threaded rod 10, the limit rod 11, the locking rod 7, and the locking bracket 8 to be installed and disassembled.

[0048] In summary, firstly, based on the valve position adjustment, the rotating ring 14 is rotated on the mounting plate 3, causing the rotating ring 14 to drive the driving plate 4 and the driven plate 5 to rotate, so as to facilitate the rotation of the rotating handle 9, the limiting rod 11, the threaded rod 10, the lifting plate 6, the locking rod 7, and the locking frame 8. When the two locking frames 8 rotate to the appropriate position, the rotating handle 9 drives the threaded rod 10 to rotate, and the lifting plate 6 moves between the threaded rod 10 and the limiting rod 11. When both locking frames 8 have moved to the appropriate height, the valve stem 2 can be limited and locked.

[0049] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
