Description

Technical Field

[0001] The utility model belongs to the technical field of pressure gauges, in particular to a fire hydrant pressure gauge. Background Art

[0002] Fire hydrant pressure gauges, also known as fire hydrant pressure meters, are important devices in fire protection systems used to monitor the water supply pressure of fire hydrants. They are mainly installed in key locations within the fire hydrant system to display the water pressure in the system in real time, thereby ensuring that the fire hydrants can provide sufficient water pressure and flow to extinguish the fire in the event of a fire.

[0003] Fire hydrant pressure gauges are typically connected to the fire hydrant system via pipes. They contain a sensing element that detects changes in water pressure within the pipes. When the water pressure changes, the sensing element converts this change into mechanical displacement or an electrical signal, which in turn drives a pointer or digital display to show the current water pressure value. This also facilitates management and monitoring by firefighters.

[0004] The original fire hydrant pressure gauges were mostly integral and square in shape, which was not exquisite in appearance and was not conducive to the production of pressure gauges and the inspection and maintenance of internal mechanisms. At the same time, the pressure gauges were large in size, which took up a lot of space when used with various types of pipe fittings in different spaces and was not conducive to the overall connection and installation.

[0005] Therefore, designing a pressure gauge that is small, beautiful and easy to install is a problem that needs to be solved by people skilled in the art. Utility Model Content

By designing a novel pressure gauge, the main body is composed of an easily detachable gauge body and cover, which facilitates installation and disassembly, makes it easier to position the internal structure, and facilitates maintenance work such as battery replacement. This makes it convenient for operators. At the same time, the PCB board is installed in the glue layer inside the glue potting tray, which improves the pressure gauge's waterproof and moisture-proof function and extends its service life.
