Description

Technical Field

[0001] This utility model relates to the field of air pressure detection technology, specifically to an air pressure detector. Background Technology

[0002] In industrial production, the use of various energy sources is indispensable, and natural gas, as one such energy source, has a wide range of applications and far-reaching impact. During industrial production, the transportation of natural gas primarily relies on pipeline systems. Given the continuously improving safety standards and the inherently high risks of industrial production, the safety of pipeline-transported natural gas is particularly important. Among numerous monitoring indicators, pressure monitoring of the gas within the pipeline is especially crucial.

[0003] In the development of the embodiments of this disclosure, we discovered several problems with the prior art. Currently, most pressure detection devices monitor pressure by installing pressure gauges outside the pipeline. However, since pipelines are typically exposed to the external environment, pressure gauges are inevitably installed outside the pipeline as well, resulting in them being subject to the long-term effects of the external environment. Over time, this prolonged exposure causes the gauge material to age, significantly shortening its service life. Utility Model Content

[0004] The purpose of this invention is to provide a barometric pressure detector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a barometric pressure detector, the core of which is a main mounting tube. To facilitate gas input and output, two pipes are specially designed on the side wall of the main mounting tube: an inlet pipe and an outlet pipe. To ensure the stability and reliability of the entire device, a fixing plate is fitted onto the main mounting tube. The fixing plate has four supports evenly distributed around the main mounting tube, forming a ring array to ensure the symmetry and balance of the entire device.

[0006] Above the support, a strong spring is installed, its main function being to provide stable elastic support. The upper end of the spring is connected to a support plate, on which a transparent protective cover is mounted. The purpose of the transparent protective cover is to protect the internal pressure gauge from external environmental influences while allowing the user to clearly observe the pressure gauge reading.

[0007] To ensure the accuracy and stability of the pressure gauge, its bottom extends through a port on the support plate and connects to the main mounting pipe. The inner ring of the port is also specially designed with a protective rubber gasket to prevent gas leakage and protect the connection parts of the pressure gauge.

[0008] Furthermore, to further enhance the stability of the device, mounting lugs are provided on the side walls of the transparent protective cover. These lugs are connected to fixing bolts via threaded connections. The bottom ends of the fixing bolts are then threaded to the support plate, thereby ensuring the overall robustness of the device.

[0009] In summary, this barometric pressure detector, through the rational layout and design of multiple components, achieves accurate measurement and effective protection of air pressure, ensuring stable operation of the equipment and user safety. The designers fully considered the stability and reliability of the device, providing stable elastic support through a ring array support and strong springs, ensuring the symmetry and balance of the device. The transparent protective cover not only protects the barometer but also facilitates data reading for the user. The design of the port and protective rubber gasket further improves the device's sealing and safety. The threaded connection of the fixing lugs and bolts strengthens the overall robustness of the device. This barometric pressure detector is not only technologically innovative but also performs excellently in practical applications, providing users with reliable and accurate air pressure measurement.

[0010] Compared with the prior art, the beneficial effects of this utility model are: since the pressure gauge is placed inside the transparent protective cover, it can effectively isolate the external environment from direct contact with the pressure gauge, reduce material aging problems caused by environmental factors, and thus extend the service life of the pressure gauge.

[0011] The transparent protective cover can prevent the pressure gauge from being accidentally impacted or damaged by human intervention. At the same time, the pressure gauge inside the protective cover is connected to the main mounting pipe through the port, ensuring the accuracy of the measurement and avoiding reading errors caused by external interference.

[0012] By installing a fixing plate on the main installation pipe and setting supports and strong springs on the fixing plate, the bearing plate and pressure gauge can be stably fixed in the proper position, maintaining stability even under pipe vibration or external impact, thus ensuring the continuity and accuracy of measurement.

[0013] Because the barometer is connected to the support plate by fixing bolts, maintenance or replacement of the barometer can be carried out quickly and easily without disassembling the entire detector, thus improving maintenance efficiency.

[0014] The supports are arranged in a ring array around the longitudinal centerline of the main installation pipe, which can accommodate pipes of different sizes and shapes, and has good versatility and adaptability.

[0015] The guide shaft ensures that the support plate can move vertically when subjected to pressure, avoiding measurement errors caused by tilting or offset and improving measurement accuracy. Attached Figure Description

[0022] The support plate 7 has a through-hole 9 in the middle. To ensure the accuracy and stability of the pressure gauge 10, its bottom end extends through the through-hole 9 on the support plate 7 and connects to the main mounting pipe 1. The inner ring of the through-hole 9 is also specially designed with a protective rubber gasket 14 to prevent gas leakage and protect the connection part of the pressure gauge 10.

The threaded connection of the fixing lug 12 and the fixing bolt 13 strengthens the overall robustness of the device. This barometric pressure detector is not only technologically innovative but also performs excellently in practical applications, providing users with reliable and accurate air pressure measurement.

[0026] Working principle: When this utility model is working, the air pressure detector is connected to the system that needs to detect air pressure through the main mounting pipe 1. The air inlet pipe 2 and the air outlet pipe 3 are used to introduce and discharge gas, respectively.

[0027] The fixing plate 4 is sleeved on the main mounting pipe 1, and the support 5 is fixed on the fixing plate 4. There are 4 supports 5 arranged in a ring array around the longitudinal central axis of the main mounting pipe 1 to provide stable support.

[0028] A strong spring 6 is located on the support 5, and its upper end is connected to the bearing plate 7. A transparent protective cover 8 is provided on the bearing plate 7, and a pressure gauge 10 is installed inside the transparent protective cover 8.

[0029] The bottom end of the pressure gauge 10 extends through the port 9 and is connected to the main mounting pipe 1. The inner ring of the port 9 is provided with a protective rubber pad 14 to protect the pressure gauge 10 from direct contact and vibration.

[0030] The guide shaft 11 passes through the support plate 7 and the strong spring 6 to ensure that the support plate 7 can move vertically when subjected to pressure, thus avoiding measurement errors.

[0031] The transparent protective cover 8 has a fixing lug 12 on its side wall, which is connected to the bearing plate 7 by fixing bolts 13, making it easy to maintain or replace the pressure gauge 10.
