Description

Technical Field

[0001] The utility model belongs to the technical field of ball valves, and particularly relates to a valve rod fixing device for processing multi-functional ball valves. Background Technique

[0002] A ball valve is a valve in which the closing member (ball) is driven by a valve rod and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, the hard-sealed V-type ball valve has a strong shearing force between its V-type ball core and the metal valve seat surfacing with hard alloy, and is especially suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any one channel to connect the other two channels. This type of valve should generally be installed horizontally in the pipeline.

[0003] When processing a ball valve, especially when processing the valve rod, it is necessary to fix the valve rod first. However, after the existing valve rod fixing device fixes the valve rod, it is not convenient to rotate and adjust the position of the valve rod, which makes it inconvenient during the processing of the valve rod. The problem that this device aims at is how to facilitate the rotation and adjustment of the valve rod after fixing. Content of the Utility Model

[0004] To solve the problems raised in the above background technique, the utility model provides a valve rod fixing device for processing multi-functional ball valves, which solves the problem of how to facilitate the rotation and adjustment of the valve rod after fixing.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides the following technical solutions: a valve stem fixing device for processing a multi-functional ball valve, including an installation box 1. A movable rod 20 is rotatably installed in the middle inside the installation box 1. A movable disk 5 is fixedly installed at the top end of the movable rod 20. A movable gear 11 is fixedly installed on the lower side of the surface of the movable rod 20. An installation ring 14 is installed on the top of the movable disk 5. Threaded rods 10 are threadedly installed around the inside of the installation ring 14. One end of each threaded rod 10 is fixedly installed with a movable knob 6. A connecting rod 21 is rotatably installed on the right side inside the installation box 1. A driving gear 22 is fixedly installed on the surface of the connecting rod 21, and the movable gear 11 is meshed with the driving gear 22. A rotating knob 7 is fixedly installed at the top end of the connecting rod 21. A moving rod 3 is slidably installed on the left side inside the installation box 1. A movable block 4 is fixedly installed at the top end of the moving rod 3. A fixed gear 18 is fixedly installed at the bottom end of the moving rod 3. A limiting disk 17 is fixedly installed in the middle of the surface of the moving rod 3. A telescopic spring 19 is fixedly installed at the bottom end of the fixed gear 18, and the bottom end of the telescopic spring 19 is fixedly connected to the bottom of the inner wall of the installation box 1, and the fixed gear 18 is meshed with the movable gear 11.

[0022] When the device is in use, first, the valve stem can be inserted into the inside of the mounting ring 14. Then, by rotating the movable knob 6, the threaded rod 10 is driven to rotate, so that one end of the threaded rod 10 can abut against the periphery of the valve stem, thus realizing the installation and fixation of the valve stem. The movable block 4 can drive the movable rod 3, the limiting disc 17 and the fixed gear 18 to move downward. Then, by rotating the knob 7, the connecting rod 21 and the driving gear 22 can be driven to rotate. Since the driving gear 22 is meshed with the movable gear 11, when the driving gear 22 rotates, it can drive the movable gear 11, the movable rod 20 and the movable disc 5 to rotate, so as to facilitate the rotational adjustment of the fixed valve stem. When the rotational adjustment is not required, the movable block 4 can be loosened, and the fixed gear 18 can be made to engage with the left side of the movable gear 11 through the telescopic spring 19, so that the movable gear 11 and the movable rod 20 cannot rotate, which is beneficial to ensuring the stability of the device during the processing. Regarding the setting of the anti-slip grooves 8, and since multiple anti-slip grooves 8 are arranged in a circular pattern on the surface of the rotating knob 7, the friction on the surface of the rotating knob 7 can be increased, making the rotating knob 7 easier to turn. Regarding the setting of the circular grooves 16, and since multiple circular grooves 16 are arranged in a circular pattern on the surface of the movable knob 6, it is convenient to increase the friction on the surface of the movable knob 6, making the movable knob 6 also easier to turn. Through the mounting plate 2 and the mounting holes 12, it is convenient to fix the device on the machine tool, which is beneficial to ensuring the valve stem processing process. And since both the mounting plate 2 and the mounting holes 12 are provided in four groups, the firmness and reliability of the device installation can be further ensured. By unscrewing the mounting screws 13, the movable bottom plate 9 can be easily disassembled, so as to facilitate the maintenance and repair of the parts inside the mounting box 1, increasing the convenience of using the device. Regarding the setting of the connecting screws 15, it is convenient to fix the mounting ring 14 on the top of the movable disc 5. And since multiple connecting screws 15 are provided, the firmness of the mounting ring 14 installation can be ensured. Regarding the anti-rust paint coating provided on the surfaces of the mounting box 1, the mounting plate 2, the movable rod 3, the movable block 4, the movable disc 5, the rotating knob 7, the movable bottom plate 9, the mounting ring 14 and the limiting disc 17, the device is not prone to rust problems, which is beneficial to extending the service life of the device and making the device more durable.

[0023] In one aspect of this embodiment, through the mounting plate 2 and the mounting holes 12, it is convenient to fix the device on the machine tool, which is beneficial to ensuring the valve stem processing process. And since both the mounting plate 2 and the mounting holes 12 are provided in four groups, the firmness and reliability of the device installation can be further ensured. By unscrewing the mounting screws 13, the movable bottom plate 9 can be easily disassembled, so as to facilitate the maintenance and repair of the parts inside the mounting box 1, increasing the convenience of using the device.

[0024] In one aspect of this embodiment, regarding the setting of the anti-slip grooves 8, since multiple anti-slip grooves 8 are arranged in a circle on the surface of the rotary knob 7, the friction on the surface of the rotary knob 7 can be increased, making the rotary knob 7 easier to turn. Regarding the setting of the circular grooves 16, since multiple circular grooves 16 are arranged in a circle on the surface of the movable knob 6, it is convenient to increase the friction on the surface of the movable knob 6, making the movable knob 6 also easy to turn.

[0025] In one aspect of this embodiment, regarding the setting of the connecting screw 15, it is convenient to fix the mounting ring 14 on the top of the movable plate 5. Since there are multiple connecting screws 15, the firmness of the installation of the mounting ring 14 can be ensured. Regarding the anti-rust paint coating provided on the surfaces of the installation box 1, installation plate 2, moving rod 3, movable block 4, movable plate 5, rotary knob 7, movable bottom plate 9, mounting ring 14 and limiting plate 17, the device is not likely to rust, which is beneficial to extending the service life of the device and making the device more durable.
