Description

Technical Field

[0001] This utility model relates to the field of pressure gauge technology, and in particular to an online detection and connection device for oilfield pressure gauges. Background Technology

[0002] In oilfield production processes such as extraction, gathering, and water injection, pressure gauges are crucial devices for monitoring fluid pressure within pipelines. Their measurement accuracy and operational stability directly impact production safety and efficiency. Oilfield pressure gauge online monitoring and connection devices, as the core connectors between pressure gauges and pipelines, must achieve rapid installation, reliable sealing, and long-term stable operation in harsh environments characterized by high pressure, strong vibration, dust, and high corrosion.

[0003] However, traditional pressure gauge connection devices still have certain drawbacks. For example, traditional oilfield pressure gauges and pipelines mostly use threaded connections, which require tightening with a wrench one turn at a time during installation, taking a long time. This means that during emergency repairs or sudden pressure anomaly detection, the lengthy installation process can delay troubleshooting. Secondly, traditional connection devices use a fixed-tightening sealing ring structure, and the sealing pressure is not adjustable, making it unsuitable for pipelines of different pressure levels in oilfields. In low-pressure gathering and transportation pipelines, the fixed tightening leads to an overly tight seal, and excessive elastic deformation of the sealing ring increases the pressure gauge's sensitivity loss. In high-pressure water injection pipelines, insufficient tightening force results in insufficient sealing pressure of the sealing ring, leading to leakage and requiring frequent shutdowns for leak repair.

At the same time, press the pressure block 14 on both sides of the limiting assembly 11. This will drive the pressure rod 13 to move the wedge block 15 along the inclined surface of the inclined insertion block 19.

When the inclined insertion block 19 is inserted into the slot 20 and corresponds to the groove 21, release the pressure block 14. Under the rebound force of the spring 18, the inclined insertion block 19 will be inserted into the corresponding groove 21, thus completing the installation of the pressure gauge 6. As needed, during installation, the pressure gauge 6 can be pressed to cause the sealing ring 8 to deform to different lengths. Then, release the pressure block 14 according to the above steps to allow the inclined insertion block 19 to be inserted into the groove 21 at different depths, thereby improving the contact tightness of the sealing ring 8 connection and thus improving the sealing effect.
