Description

Technical Field

[0001] This utility model relates to the field of pressure transmitter technology, and in particular to a pressure transmitter mounting structure. Background Technology

[0002] A pressure transmitter is an industrial device mainly used to measure the pressure of media such as liquids, gases or steam, and convert the pressure signal into a standard electrical signal output for long-distance transmission and subsequent control system use. It is usually composed of a sensor, a measuring circuit, a signal processing circuit and an output interface. The sensor senses the pressure and converts it into a measurable physical quantity. After conversion and processing by the measuring circuit and the signal processing circuit, a standard signal is finally output.

[0003] When installing existing flanges, it is necessary to ensure that the mating surfaces of the two flanges are parallel, the bolt holes are aligned, and the top two bolt holes on horizontal pipes must be horizontal. On vertical pipes, the connection line of the two bolt holes closest to the wall must be parallel to the wall. Insufficient installation accuracy may result in a loose flange connection, affecting sealing performance. Furthermore, installation will be time-consuming and labor-intensive, causing difficulties for workers and impacting work hours.

[0004] Therefore, this utility model provides a pressure transmitter mounting structure. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pressure transmitter mounting structure.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a pressure transmitter mounting structure, including a delivery pipe, an extension pipe and a pressure gauge, and further comprising:

[0007] A connecting assembly; the connecting assembly includes a top connecting plate sleeved on the top end of the outer side of the extension tube and a fixed connecting plate fixedly connected to the bottom end. The top connecting plate and the fixed connecting plate are equipped with connecting screws arranged in a circular array inside, and the connecting screws are threaded with rotating caps on their outer sides.

[0008] Synchronous rotation assembly; the synchronous rotation assembly includes a first rotating column and a second rotating column, the top end of the first rotating column is fixedly connected to a driving toothed column, and the top end of the second rotating column is fixedly connected to a driven toothed column.

[0009] In a preferred embodiment, the pressure gauge is fixedly connected to the top of the delivery pipe via an extension tube.

[0010] In a preferred embodiment, the bottom end of the first rotating column is rotatably connected to the inside of the top connecting plate, and the bottom end of the second rotating column is rotatably connected to the top connecting plate in a circular array.

[0011] In a preferred embodiment, a throttle is fixedly connected to the top of the active gear column, the active gear column and the driven gear column are meshed, and the internal thread of the second throttle column is connected to the outside of the connecting screw.

[0012] In a preferred embodiment, the top connecting plate is internally fixedly connected to the outside of the pressure gauge.

[0013] In a preferred embodiment, a sealing gasket is provided between the top connecting plate and the fixed connecting plate, and the sealing gasket is fixedly connected to the adjacent end of the top connecting plate and the fixed connecting plate by connecting screws.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By aligning the top connecting plate connected to the pressure gauge with the fixed connecting plate on the delivery pipe, and aligning the connecting screws with the through holes of the top and fixed connecting plates, the rotating handle drives the active gear column to rotate synchronously, thereby ensuring that the connecting screws between the top and fixed connecting plates are tightened evenly, ensuring that the connecting surfaces of the two flanges are parallel and the bolt holes are aligned. The advantage of this design is that by rotating the handle, the active and driven gear columns can be rotated evenly and synchronously, and the flanges are evenly connected using the principle of gear transmission. This not only reduces the difficulty of manual operation but also improves the installation accuracy, making the flange connection more stable and sealed. In addition, by rotating the rotating cap to drive the driven and active gear columns to rotate synchronously, the torque during the installation process is further increased, ensuring the firmness of the flange connection.

[0024] 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.

[0025] like Figure 1 As shown, this embodiment provides a technical solution: a pressure transmitter mounting structure, including a delivery pipe 1, an extension pipe 2 and a pressure gauge 3, wherein the pressure gauge 3 is fixedly connected to the top end of the delivery pipe 1 through the extension pipe 2;

[0026] The main function of the delivery pipe 1 is to transport the measured medium, ensuring that the medium can flow smoothly from the source to the location of the pressure transmitter. The extension pipe 2 connects the top end of the delivery pipe 1 to the pressure gauge 3, so that the pressure gauge 3 can be easily installed at the top end of the delivery pipe 1. This transition connection method can better adapt to delivery pipes 1 and pressure gauges 3 with different diameters or different interface forms, increasing the flexibility and adaptability of the installation. The pressure gauge 3 is the core component of the entire installation structure. Its main function is to measure the pressure of the medium in the delivery pipe 1. It converts the pressure signal of the medium into a standard electrical signal through internal sensors and conversion circuits.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a connecting component 4; the connecting component 4 includes a top connecting plate 41 sleeved on the top of the outer side of the extension tube 2 and a fixed connecting plate 43 fixedly connected to the bottom. The inside of the top connecting plate 41 is fixedly connected to the outside of the pressure gauge 3. The inside of the top connecting plate 41 and the fixed connecting plate 43 are provided with connecting screws 44 in a circular array. A sealing gasket 42 is provided between the top connecting plate 41 and the fixed connecting plate 43. The sealing gasket 42 is fixedly connected to the near end of the top connecting plate 41 and the fixed connecting plate 43 by the connecting screws 44. A rotating cap 45 is threaded on the outside of the connecting screws 44.

[0028] The top connecting plate 41 is sleeved on the outer top of the extension tube 2, and its interior is fixedly connected to the outside of the pressure gauge 3, thereby connecting the pressure gauge 3 to the extension tube 2. This ensures that the pressure gauge 3 can be stably installed at the top of the extension tube 2, realizing the measurement and transmission of pressure signals. The connecting screws 44 are inserted in a circular array inside the top connecting plate 41 and the fixed connecting plate 43. By tightening the connecting screws 44, the top connecting plate 41 and the fixed connecting plate 43 are tightly connected together, thereby realizing a firm connection between the extension tube 2 and the pressure gauge 3, ensuring that there will be no loosening or falling off during use. The sealing gasket 42 can effectively fill the small gap between the top connecting plate 41 and the fixed connecting plate 43, preventing gas or liquid from leaking from the connection, ensuring the sealing performance and measurement accuracy of the system. The rotating cap 45 is threaded to the outside of the connecting screw 44. By rotating the rotating cap 45, the connecting screw 44 can be easily tightened or loosened, thereby realizing quick assembly and disassembly between the top connecting plate 41 and the fixed connecting plate 43, improving the efficiency of installation and maintenance.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it also includes a synchronous rotation assembly 5; the synchronous rotation assembly 5 includes a first rotating column 51 and a second rotating column 53. The bottom end of the first rotating column 51 is rotatably connected to the inside of the top connecting plate 41, and the bottom end of the second rotating column 53 is rotatably connected to the top connecting plate 41 in a circular array. The internal thread of the second rotating column 53 is connected to the outside of the connecting screw 44. The top end of the first rotating column 51 is fixedly connected to a driving toothed column 52, and the top end of the second rotating column 53 is fixedly connected to a driven toothed column 54. The driving toothed column 52 and the driven toothed column 54 are meshed. The top end of the driving toothed column 52 is fixedly connected to a throttle 55.

[0030] Rotating column 51 provides a basic support point and rotation center for the entire rotating system, ensuring rotational stability. The bottom of rotating column 53 is arranged in a circular array and rotatably connected to the top connecting plate 41. This layout allows rotating column 53 to be evenly distributed in multiple positions, providing multi-point support for the entire rotating system. The driving gear column 52 is fixedly connected to the top of rotating column 51 and is the core component for power transmission in the synchronous rotation assembly 5. Through meshing with the driven gear column 54, it transmits the rotational power of rotating column 51 to rotating column 53, thereby enabling the driving gear to rotate. The toothed column 52 is threaded onto the connecting screw 44 to achieve synchronous tightening. The driven toothed column 54 meshes with the driving toothed column 52, receives the power transmitted from the driving toothed column 52, and transmits it to the rotating column 53, enabling the rotating column 53 to rotate synchronously with the rotating column 51. The throttle 55 is the operating component for the operator to manually control the synchronous rotation assembly 5. By rotating the throttle 55, the operator can easily control the rotation of the driving toothed column 52, thereby realizing the start, stop, and speed adjustment of the entire synchronous rotation assembly 5.

[0031] Working principle:

[0032] like Figure 1 - Figure 5 As shown:

[0033] In use: Align the top connecting plate 41 connected to the pressure gauge 3 with the fixed connecting plate 43 on the delivery pipe 1, then align the connecting screw 44 with the through holes on the top connecting plate 41 and the fixed connecting plate 43, and then turn the handle 55. When the handle 55 turns, it drives the active gear 52 to rotate synchronously, and the bottom rotating column 51 rotates on the top connecting plate 41, so that the active gear 52 rotates synchronously through the rotating column 51, thereby enabling the active gear 52 to rotate evenly on the top connecting plate 41. Subsequently, when the active gear 52 rotates, it will drive the outer driven gear 54 to rotate synchronously. The driven gear 54 rotates, and the rotating pin 53 at the bottom of the driven gear 54 can rotate on the outside of the top connecting plate 41. Then, the connecting screw 44 will cause the top connecting plate 41 and the fixed connecting plate 43 to tighten due to the threaded connection of the driven gear 54. Then, the sealing gasket 42 ensures the sealing. When the top connecting plate 41, the sealing gasket 42 and the fixed connecting plate 43 are connected together, the driven gear 54 at the bottom is rotated by rotating one of the rotating caps 45, which drives the driving gear 52 to rotate, so that the other driven gears 54 on the outside will also rotate synchronously, which increases the torque and achieves synchronization.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
