Description

Technical Field

[0001] The utility model relates to the technical field of oil pressure level gauges, in particular to a digital oil pressure level gauge which is easy to install. Background Art

[0002] The types of oil pressure level gauges include tuning fork vibration type, magnetic levitation type, pressure type, ultrasonic type, sonar wave, magnetic flap, radar, etc. Among them, the magnetic flap level gauge must be installed vertically and a ball valve must be installed between the container guide pipe for easy maintenance and cleaning.

[0003] In view of this, Chinese Patent No. CN210089797U proposes a liquid level gauge that is easy to install and disassemble. It is easy to use and can quickly complete the installation and disassembly of the liquid level transmitter body to improve efficiency. Chinese Patent No. 209605897U proposes a new type of liquid level gauge that is easy to install. It moves in the fastening cover through the connecting pipe and the connecting flange to achieve quick connection. It does not require bolt fixing and saves time. Chinese Patent No. 210981424U proposes an integrated liquid level gauge that is easy to install. By setting a limit ring, the detection head is fixed, which is convenient for the later reinforcement of the thread, and then it is easy to install, making the equipment more flexible, easy to store and maintain.

[0004] In the above patents, flanges with screws are generally used for fixing during installation. Although this effectively ensures a firm connection, a wrench is usually required when disassembling, inspecting, and repairing the level gauge. Some screws that have not been moved for a long time may have rusted and are difficult to turn with a wrench, which brings a lot of inconvenience to the staff. In addition, the surface of the level gauge lacks a protective barrier. If the glass tube of the level gauge hits a hard object, it is easy to break, causing damage to the level gauge.

[0005] Based on this, this solution proposes a digital oil pressure level gauge that is easy to install. Utility Model Content
