Description

Technical Field

[0001] This utility model belongs to the field of valve opening detection technology, specifically relating to an online valve opening monitoring device. Background Technology

[0002] In the current technology, whether the valve core is leaking internally is basically determined by manual inspection. The inspector makes a judgment by feeling the temperature of the pipe walls on both sides of the valve core or by listening to the airflow sound with a stethoscope. The manual inspection method is not only labor-intensive for workers, but also has poor real-time performance and blind spots in time and space. It cannot detect safety hazards in time, and it cannot monitor the real-time opening of the valve core.

[0003] Chinese Patent Application No. 202421051885.3 discloses an online monitoring device for the opening degree of a pipeline valve, including a valve body. A valve stem is located at the top of the valve body, and the bottom end of the valve stem is connected to a valve core inside the valve body. A first monitoring component and a second monitoring component for monitoring the valve core opening degree are located outside the valve stem. The first monitoring component includes a handle, which is attached to the outside of the top of the valve stem. A pointer is installed on the rear side of the handle. This invention allows the pointer to be rotated with the handle, displaying the valve core opening angle in real time in conjunction with a first scale line. Simultaneously, the valve stem, through a threaded connection with a movable plate on the valve stem, can move the movable plate, which is limited by a fixed column, upwards. The movable plate, with the aid of the pointer and the second scale line, can then display the rotational opening angle of the valve core inside the valve body in real time, thus enabling operators to monitor the valve core opening angle in real time.

[0004] The aforementioned disclosed patents have the following problems when used:

[0005] 1. The device is not equipped with a support component, so it cannot effectively support the valve body during use. This is not conducive to the installation and fixation of the device, nor is it convenient to adjust the installation height according to the pipelines at both ends, thus its practicality is low.

[0006] 2. This device only uses an indicator to show the valve opening status. In case of abnormal situations, it cannot promptly remind staff to pay attention to the valve, which is not very safe. Utility Model Content

[0023] 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.

[0024] Example 1

[0025] Please see Figure 1-5The present invention provides the following technical solution: an online valve opening monitoring device, comprising a valve body 1, a vertical plate 7 fixedly connected to the top of the valve body 1, a valve stem 5 provided on one side of the vertical plate 7, a handle 3 installed on the top of the valve stem 5, an indicator 6 fixedly connected to one end of the handle 3, an arc plate 4 provided at the bottom of the indicator 6, a support component 2 provided at the bottom of the valve body 1, and a warning component 8 fixedly connected to the side of the vertical plate 7 away from the valve stem 5.

[0026] Specifically, the support assembly 2 includes an installation assembly 21, a fixing plate 22, a motor 23, a screw 24, a guide groove 25, a guide rod 26, a support block 27, and a screw hole 28. The installation assembly 21 is located at the bottom of the valve body 1. The fixing plate 22 is fixedly attached to the top surface of the installation assembly 21. The motor 23 is installed inside the installation assembly 21. The screw 24 is installed at the top output end of the motor 23. The support block 27 is located at the top of the screw 24. The screw hole 28 is opened on the bottom surface of the support block 27. The guide rod 26 is fixedly attached to both sides of the support block 27. The guide groove 25 is opened on the side surface of the fixing plate 22 near the guide rod 26.

[0027] By adopting the above technical solution, when using the support component 2, the component is first adjusted according to the height and position of the pipeline. The position of the valve body 1 is fixed by the installation component 21. When the height of the valve body 1 needs to be adjusted, the motor 23 drives the screw 24 to rotate, thereby further moving the support block 27 upward. At the same time, the guide rods 26 fixed on both sides of the support block 27 slide synchronously in the guide groove 25, thereby guiding the support block 27 and improving the stability of the movement of the support block 27. The support block 27 improves the support function of the device. When the height does not need to be adjusted, the valve body 1 can be supported and fixed by the fixing plates 22 on both sides and the support block 27, thereby further fixing the pipelines connected to both ends of the valve. This avoids the problem of leakage at the connection due to the non-fixed position of the pipelines at both ends during use, and enhances practicality.

[0028] Specifically, the mounting assembly 21 includes a mounting plate 211, a cavity 212, an extension plate 213, a bidirectional screw 214, a threaded plate 215, and a mounting groove 216. The bottom of the valve body 1 is provided with a mounting plate 211, the top surface of the mounting plate 211 is provided with a mounting groove 216, the inside of the mounting plate 211 is provided with a cavity 212, the inside of the cavity 212 is provided with an extension plate 213, one side surface of the extension plate 213 is fixedly connected to a threaded plate 215, and the internal threads of the threaded plate 215 are through which the bidirectional screw 214 passes.

[0029] By adopting the above technical solution, when installing component 21, if the installation position is suitable, it can be directly installed through the installation hole on the top of the mounting plate 211. When the installation position needs to be adjusted, the double-acting screw 214 can be rotated by handwheel. The double-acting screw 214 drives the threaded plate 215 and the extension plate 213 to move. When the installation hole on the surface of the extension plate 213 reaches the appropriate position, the valve body 1 can be installed and fixed through the installation hole, which improves the stability of the device during use and expands its applicable range.

[0030] Specifically, a handwheel is fixed to one end of the bidirectional screw 214, a bearing is provided at the other end of the bidirectional screw 214, and mounting holes are provided inside the extension plate 213.

[0031] By adopting the above technical solution, the operator can easily rotate the bidirectional screw 214 via the handwheel. The bearing at one end of the bidirectional screw 214 can provide a limiting support for the bidirectional screw 214 without affecting its rotation. The valve body 1 can be quickly installed in the appropriate position through the cooperation of the mounting hole and bolt, thus improving work efficiency.

[0032] In this embodiment, when using the support component 2, the component is first adjusted according to the height and position of the pipeline. The position of the valve body 1 is fixed by the mounting component 21. When the height of the valve body 1 needs to be adjusted, the motor 23 drives the screw 24 to rotate, thereby further moving the support block 27 upward. At the same time, the guide rods 26 fixed on both sides of the support block 27 slide synchronously in the guide groove 25, thereby guiding the support block 27 and improving the stability of the movement of the support block 27. The support block 27 improves the support function of the device. When the height adjustment is not required, the valve body 1 can be supported and fixed by the fixing plates 22 on both sides and the support block 27, which can further fix the pipelines connected to both ends of the valve, avoiding the problem of leakage at the connection due to the non-fixed position of the pipelines at both ends during use, and enhancing the... For practicality, when installing component 21, if the installation position is suitable, it can be directly installed through the mounting holes on the top of the mounting plate 211. When the installation position needs to be adjusted, the double-acting screw 214 can be rotated by handwheel. The double-acting screw 214 drives the threaded plate 215 and the extension plate 213 to move. When the mounting holes on the surface of the extension plate 213 reach the appropriate position, the valve body 1 can be installed and fixed through the mounting holes. This improves the stability of the device during use and expands its application range. The handwheel makes it easy for the operator to rotate the double-acting screw 214. The bearing at one end of the double-acting screw 214 can provide limit support for the double-acting screw 214 without affecting its rotation. The valve body 1 can be quickly installed in the appropriate position through the cooperation of the mounting holes and bolts, improving work efficiency.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that, specifically, the warning component 8 includes a support frame 81, a warning light 82, a limiting groove 83, a spring 84, a movable groove 85, a movable rod 86, a switch 87, and a limiting plate 88. The support frame 81 is fixed to one side surface of the vertical plate 7. The top surface of the support frame 81 has a movable groove 85. A limiting groove 83 is provided on one side of the movable groove 85. A movable rod 86 is provided inside the movable groove 85. A switch 87 is installed on the top of the movable rod 86. A spring 84 is provided on one side of the movable rod 86. A limiting plate 88 is provided on the side of the movable rod 86 near the limiting groove 83. A warning light 82 is installed on one side of the support frame 81.

[0035] By adopting the above technical solution, when using the warning component 8, the position of the switch 87 is first adjusted according to the needs. During adjustment, the limit plate 88 is pulled upward first, and then the movable rod 86 is pushed to the appropriate position. Then, the limit plate 88 is engaged with the limit groove 83 to fix the position of the movable rod 86 and the switch 87. When the valve opening is abnormal due to abnormal internal pressure in the pipeline, the handle 3 will gradually rotate around the valve stem 5. When the handle 3 contacts the switch 87, the switch 87 is turned on and the warning light 82 is lit. The warning light 82 reminds the staff to pay attention to the valve opening, thus avoiding safety accidents and further improving the safety of the device and perfecting the warning function.

[0036] Specifically, a fixing block is installed between the movable rod 86 and the limiting plate 88, and a rotating shaft is provided inside the fixing block.

[0037] By adopting the above technical solution, when the limit plate 88 is pulled, the limit plate 88 will rotate around the pivot, thereby eliminating the engagement between the limit plate 88 and the limit groove 83, making it easier for the operator to adjust the position of the switch 87 and the movable rod 86, and enhancing practicality.

[0038] In this embodiment, when using the warning component 8, first adjust the position of the switch 87 according to the requirements. During adjustment, first pull the limit plate 88 upward, then push the movable rod 86 to the appropriate position, and then engage the limit plate 88 with the limit groove 83 to fix the position of the movable rod 86 and the switch 87. When the valve opening is abnormal due to abnormal internal pressure in the pipeline, the handle 3 will gradually rotate around the valve stem 5. When the handle 3 contacts the switch 87, the switch 87 is turned on and the warning light 82 is lit. The warning light 82 reminds the staff to pay attention to the valve opening, avoiding safety accidents and further improving the safety of the device and perfecting the warning function. When the limit plate 88 is pulled, the limit plate 88 will rotate around the pivot, thereby canceling the engagement between the limit plate 88 and the limit groove 83, making it easier for the operator to adjust the position of the switch 87 and the movable rod 86, and enhancing practicality.

[0039] In this utility model, the warning light 82 is a previously disclosed technology, and the selected model is LTE-1101J.

[0040] The structure and operating principle of the valve body 1, handle 3, arc plate 4, valve stem 5, indicator 6 and vertical plate 7 in this utility model have been disclosed in an online monitoring device for the opening degree of a pipeline valve disclosed in Chinese patent application number 202421051885.3.

[0041] The working principle and usage process of this utility model: This utility model is for adjusting a pipeline valve opening online monitoring device. When using the support component 2, the component is first adjusted according to the height and position of the pipeline. The position of the valve body 1 is fixed by the mounting component 21. When it is necessary to adjust the height of the valve body 1, the motor 23 drives the screw 24 to rotate, thereby further moving the support block 27 upward. At the same time, the guide rods 26 fixed on both sides of the support block 27 slide synchronously in the guide groove 25, thereby guiding the support block 27 and improving the stability of the movement of the support block 27. The support block 27 improves the support function of the device, and when it is not necessary to adjust the height of the valve body 1, the support block 27 can be adjusted upward. When adjusting the height, the valve body 1 can be supported and fixed by the fixing plates 22 and support blocks 27 on both sides, which can further fix the connecting pipes at both ends of the valve, avoiding leakage at the connection due to the unstable position of the pipes at both ends during use, thus enhancing practicality. When installing component 21, if the installation position is suitable, it can be directly installed through the mounting hole on the top of the mounting plate 211. When the installation position needs to be adjusted, the double-acting screw 214 can be rotated by handwheel, which drives the threaded plate 215 and the extension plate 213 to move. When the mounting hole on the surface of the extension plate 213 reaches the appropriate position, it can be installed through the mounting hole. Installing and fixing the valve body 1 improves the stability of the device during use and expands its application range. The handwheel allows operators to easily rotate the bidirectional screw 214. The bearing at one end of the bidirectional screw 214 provides limiting support without affecting its rotation. The valve body 1 can be quickly installed in the appropriate position through the mounting holes and bolts, improving work efficiency. This utility model adjusts a pipeline valve opening online monitoring device. When using the warning component 8, first adjust the position of the switch 87 according to requirements. During adjustment, first pull the limit plate 88 upwards, and then push the movable rod 86 to the appropriate position. The limit plate 88 is then engaged with the limit groove 83, fixing the positions of the movable rod 86 and the switch 87. When the valve opening is abnormal due to abnormal internal pressure in the pipeline, the handle 3 will gradually rotate around the valve stem 5. When the handle 3 contacts the switch 87, the switch 87 is turned on and the warning light 82 illuminates. The warning light 82 illuminates to remind the staff to pay attention to the valve opening, thus avoiding safety accidents and further improving the safety of the device and perfecting the warning function. When the limit plate 88 is pulled, the limit plate 88 will rotate around the pivot, thereby canceling the engagement between the limit plate 88 and the limit groove 83, making it easier for the operator to adjust the positions of the switch 87 and the movable rod 86, and enhancing practicality.
