[0002] Hydrostatic testing is a common testing method used to evaluate the sealing performance and pressure resistance of pipelines, containers and equipment. In the industrial field, hydrostatic testing is widely used in various industries, including construction, petrochemical, aerospace and energy.

The reinforcement ring is movably installed on the periphery of the movable rod at the top of the fixing ring, and a limiting ring is movably installed on the periphery of the movable rod at the bottom of the fixing ring. A water pressure detector is fixedly connected to the top of the conduit, and a water pressure detection gauge is fixedly connected to the surface of the conduit.

[0004] By adopting the above-mentioned technical scheme, the present application can detect the water pressure of the fire hydrant in electronic and physical ways respectively through the coordinated use of a water pressure test gauge, a water pressure detector, a reinforcement ring and a limit ring, so as to facilitate the staff to compare the data, make the known water pressure detection data more accurate, and also improve the stability of the device installed on the fire protection structure, prevent the device from loosening and causing changes in water pressure, thereby ensuring the accuracy of the device's water pressure detection data. However, according to the above-mentioned technical scheme, when connecting the detector to the fire hydrant, the connecting head can only be connected and fixed to the fire hydrant by rotating the entire device. When the detector is rotated and connected, the water pressure test gauge is prone to tilt, which is not convenient for the staff to observe. At the same time, the gap between the connecting head and the fire hydrant is also prone to leakage, affecting the accuracy of the water pressure detection, thereby resulting in the problem of poor practicality.

[0005] Therefore, those skilled in the art provide a leak-proof fire-fighting water pressure detector to solve the problems raised in the above-mentioned background technology. Utility Model Content
