Description

Technical Field

[0001] This utility model relates to the field of valve opening sensors, specifically a non-contact valve opening sensor. Background Technology

[0002] In the field of industrial automation, valves are key components of fluid control, and the accurate measurement of their opening degree is crucial for the stable operation of the system. Most existing valve opening degree sensors adopt contact measurement methods, such as potentiometer sensors, which obtain opening degree information through direct contact between the mechanical structure and the valve shaft. However, such sensors have obvious drawbacks: during long-term use, the mechanical contact parts are prone to wear, resulting in a decrease in measurement accuracy and an increase in maintenance costs; under harsh working conditions such as high temperature, high pressure, and strong corrosion, the service life of the sensor is greatly shortened, and it may even cause safety accidents.

[0003] While non-contact valve opening sensors have seen some development, they generally suffer from limited installation options. Some sensors are only applicable to specific pipe diameters or valve types, making them difficult to use universally across different pipe and valve systems, which greatly restricts their application scope. Furthermore, existing non-contact sensors are susceptible to electromagnetic interference, leading to data fluctuations and failing to meet the high-precision measurement requirements of complex industrial environments. Therefore, it is necessary to design a non-contact valve opening sensor to address these issues. Utility Model Content

[0021] 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.

[0022] Example 1

[0023] Please refer to Figure 1-5 As shown, this utility model provides a non-contact valve opening sensor, including a valve opening sensor body 1. A cover plate 2 is bolted to the top of the body 1. Two fixing plates 3 are fixedly connected to both sides of the body 1. An installation component is installed on one side of the fixing plate 3. A fixing component is installed at the bottom of the body 1. The fixing component and the installation component are used to fix the body 1 in different installation environments.

[0024] It should be added that the cross-section of the fixing plate 3 is L-shaped, and the mounting parts on one side of the fixing plate 3 can move upward or downward, so that the mounting parts can install and fix the plate structure. The fixing parts can bind the body 1 to cylindrical structures such as tubular and rod-shaped structures, so that the fixing parts can install and fix the body 1, thereby improving the environmental adaptability and fixing stability of the body 1.

[0025] Specifically, the mounting component includes a drive block 4 that is slidably connected to one side of the fixed plate 3, a first screw 5 that passes through the inner side of the fixed plate 3, a clamping plate 6 that is fixedly connected to the other side of the drive block 4, the first screw 5 passing through the drive block 4 and being screwed to it, and mounting plates 17 that are fixedly connected to both sides of the body 1 and near the end, and a fixing hole 18 for bolts to pass through is opened on one side of the mounting plate 17.

[0026] The first screw 5 can drive the clamping plate 6 to move up and down through the driving block 4. While the clamping plate 6 moves upward, it moves close to the bottom of the body 1 to install and fix the plate structure. The fixing plate 3 and the clamping plate 6 clamp and fix the body 1 to prevent the body 1 from shaking or vibrating violently. After the mounting plates 17 on both sides of the body 1 are attached to the plate structure, they can also be screwed and fixed by bolts through the fixing holes 18 to improve the stability and adaptability of the installation and fixing of the body 1.

[0027] More specifically, the fasteners include a fixing strap 7 fixedly connected to the bottom of the body 1 and near one side, a fixing frame 8 fixedly connected to the other side of the body 1 and located between two fixing plates 3, a second screw 9 passing through one side of the fixing frame 8, a locking block 10 being fitted onto the second screw 9 through the fixing part 901, a locking groove 11 being provided on the other side of the body 1 and located on one side of the fixing frame 8, and a plurality of evenly arranged movable holes 12 being provided on one side of the fixing strap 7, the second screw 9 passing through the fixing frame 8 and being screwed to it, the fixing part 901 being rotatably connected to the locking block 10 and not disengaging, and guide rods 13 being fixedly connected to the other side of the locking block 10 and located on both sides of the second screw 9, the guide rods 13 passing through the fixing frame 8 and being slidably connected to it.

[0028] It should be added that the fixing strap 7 is made of rubber and wraps around the outside of the tubular, rod-shaped or other structures. The fixing strap 7 passes through one side of the fixing frame 8. The second screw 9 drives the locking block 10 through the movable hole 12 on one side of the fixing strap 7 and inserts it into the locking groove 11. This allows the locking block 10 to install and fix the fixing strap 7. The guide rod 13 can guide and support the locking block 10 to prevent the locking block 10 from shifting or shaking, thereby improving the practicality and stability of the installation and fixing of the body 1.

[0029] Furthermore, a pad 14 is fixedly connected to the bottom of the main body 1, and anti-slip pads 15 are laid on one side of the fixing strap 7 and the other side of the clamping plate 6. Multiple mounting holes 16 are opened on one side of the anti-slip pads 15, and the mounting holes 16 correspond one-to-one with the movable holes 12.

[0030] Among them, the pad 14 at the bottom of the body 1 is made of rubber. The pad 14 at the bottom of the body 1 is attached and fixed to the valve structure to prevent the body 1 from sliding or shaking, and can also reduce the vibration amplitude of the body 1. The anti-slip pads 15 on one side of the fixing strap 7 and the clamping plate 6 can increase the anti-slip properties of the fixing strap 7 and the clamping plate 6 in contact with the valve structure.

[0031] Working principle: First, select the installation method according to the valve structure, and place the body 1 near the valve. Then, wrap the fixing strap 7 around the outside of the tubular, rod-shaped or other structure. At the same time, the fixing strap 7 passes through one side of the fixing frame 8. Then, the second screw 9 rotates on one side of the fixing frame 8. At this time, the second screw 9 drives the locking block 10 through the fixing part 901 to pass through the movable hole 12 on one side of the fixing strap 7 and insert into the locking groove 11. At the same time, the locking block 10 locks the fixing strap 7 to install and fix the body 1. Meanwhile, the guide rod 13 guides and supports the locking block 10.

[0032] Alternatively, based on the plate-like structure, the first screw 5 can drive the clamping plate 6 to move upward through the driving block 4. While the clamping plate 6 moves upward, it moves close to the bottom of the body 1 to install and fix the plate-like structure. At this time, the fixing plate 3 and the clamping plate 6 clamp and fix the body 1.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
