Description

Technical Field

[0001] This utility model relates to the field of pressure monitoring equipment technology, and more specifically, to a pressure monitoring device. Background Technology

[0002] In modern industry, exhaust systems are commonly used in production workshops to remove water vapor generated during production, preventing it from affecting the process. To ensure stable production, the negative pressure of the exhaust system must be maintained within a certain range, requiring pressure monitoring equipment. However, during exhaust, water vapor condenses on the pressure gauge's monitoring pipes. This condensate can enter and clog the pipes, causing discrepancies between the measured and actual pressure readings, thus reducing the accuracy of the exhaust system's pressure monitoring. If this abnormal value exceeds the set range required by the production process, it can also cause abnormal equipment shutdowns, reducing equipment uptime. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a pressure monitoring device, including a pressure monitoring device 10. The pressure monitoring device 10 is a prior art device for measuring air pressure in pipelines. Its specific internal structure and working principle will not be described in detail in this technical solution. A monitoring pipeline 101 is provided on one side of the pressure monitoring device 10, and a drying element 30 is provided on one side of the monitoring pipeline 101. Connectors 20 are provided on both the left and right sides of the drying element 30. A fixing groove 201 is opened on the side of the connector 20. Multiple push rods 202 distributed circumferentially in the fixing groove 201 are provided. A support spring 203 is sleeved on the outside of the push rod 202. One end of the 02 is provided with a locking block 204. The outside of the connector 20 is provided with multiple operating grooves 21 that are circumferentially distributed. The inside of the operating groove 21 is provided with a first movable plate 211. A second movable plate 212 is slidably arranged on the first movable plate 211. The inside of the drying component 30 is provided with an activated carbon pack 301. The activated carbon can absorb the moisture in the water vapor, thereby achieving the drying effect and preventing the condensate of the water vapor from entering the monitoring pipe 101 and causing blockage, which would reduce the accuracy of the measurement. Filter screens 302 are provided on both the left and right sides of the drying component 30 to filter and prevent carbon ash from flying out during the drying process of the activated carbon.

[0028] In this embodiment, the number of operating slots 21 is equal to the number of push rods 202. The left connector 20 is threadedly connected to the monitoring pipe 101, and the right connector 20 can be connected to the water vapor conveying pipe to be monitored.

[0029] In this embodiment, the connector 20 has the same number of fixing holes as the operating groove 21. The two ends of the fixing holes are connected to the operating groove 21 and the fixing groove recess 201, respectively. The push rod 202 is slidably connected to the fixing holes.

[0030] The other end of the push rod 202 is fixedly provided with a stop block 205. The diameter of the stop block 205 is larger than the diameter of the fixing hole, which can prevent the push rod 202 from moving out of the operating slot 21. The two ends of the support spring 203 are respectively abutted between the stop block 205 and the operating slot 21. The elastic potential energy of the support spring 203 can be used to fix the drying element 30 through the locking block 204, which facilitates the periodic replacement of the drying element 30 to ensure the accuracy of the pressure monitoring device 10 in monitoring the steam pressure.

[0031] In this embodiment, a rotating rod 213 is fixedly installed on the second movable plate 212. The two ends of the rotating rod 213 are rotatably connected to the left and right sides of the operating groove 21, respectively. A plurality of sleeve rods 214 are provided between the left and right sides of the operating groove 21. A spring clip 215 is sleeved on the outside of the sleeve rod 214. Pushing the first movable plate 211 upward can shorten the distance between the first movable plate 211 and the second movable plate 212. Rotating the first movable plate 211 can insert the first movable plate 211 into the operating groove 21 for locking and engagement. During this activity, the first movable plate 211 pushes the stop block 205 to move closer to the push rod 202, which can push the locking block 204 to move closer to the drying component 30.

[0032] It should be noted that the spring clip 215 is located on the back of the first movable plate 211 and the second movable plate 212, and the end of the first movable plate 211 is engaged in the operating groove 21.

[0033] It is understandable that both the first movable plate 211 and the second movable plate 212 are arc-shaped, and the outer side of the first movable plate 211 is provided with a groove 216 to facilitate lifting the first movable plate 211 for operation.

[0034] In this embodiment, a locking element 304 is fixedly provided at both the left and right ends of the outer side of the drying element 30, and a plurality of locking slots 303 are provided on the outer side of the locking element 304 in a circumferentially equidistant manner.

[0035] It should be emphasized that the number of slots 303 and the number of blocks 204 are the same. The blocks 204 are inserted into the slots 303 and fit with them with a gap. The blocks 204 limit the position of the card 304, thus fixing the drying component 30 and the connector 20.

[0036] Specifically, the working principle of this pressure monitoring device is as follows:

[0037] In use, first, screw the left connector 20 onto the monitoring pipe 101. Then, fix the steam delivery pipe to the right connector 20. After the pipe is installed, open the valve of the steam delivery pipe to deliver steam to the monitoring pipe 101 for pressure testing. During the delivery process, the activated carbon bag 301 absorbs the moisture in the steam to achieve drying, preventing condensation from entering the monitoring pipe 101 and clogging the pipe, thus reducing the accuracy of the pressure monitoring device 10. In addition, the drying element 30 can be replaced periodically to ensure the drying effect of the steam, thereby ensuring the accuracy of the pressure monitoring device 10. Specifically, the groove 216 pushes the first movable plate 211 upward to shorten the distance between the first movable plate 211 and the second movable plate 212. The distance between the first movable plate 211 and the second movable plate 212 is shortened by rotating the first movable plate 211, which can be inserted into the operating groove 21 for engagement. During this movement, the first movable plate 211 pushes the stop block 205 to move closer to the push rod 202, which in turn pushes the locking block 204 to move closer to the drying element 30, and inserts the locking block 204 into the slot 303 to fix the drying element 30. At the same time, due to the elastic potential energy of the spring clip 215, the bottom end of the first movable plate 211 can be inserted into and fixed in the operating groove 21. When it is necessary to replace the drying element 30, it is only necessary to push the first movable plate 211 upward through the groove 216 to shorten the distance between the first movable plate 211 and the second movable plate 212, and rotate the first movable plate 211 to move outward of the connector 20, so that the locking block 204 can be removed from the slot 303.

[0038] It should be noted that the specific models and specifications of the pressure monitoring device 10, connector 20, drying element 30, activated carbon bag 301, and filter screen 302 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0039] The power supply and operating principle of the pressure monitoring device 10 are clear to those skilled in the art and will not be described in detail here.
