Description

Technical Field

[0001] The utility model relates to the technical field of pipe network pressure detection, in particular to a pressure measuring device used for pipe network dispatching in a water plant. Background Art

[0002] Water plant network dispatching is an important part of the urban water supply system. Its main task is to achieve remote supervision and intelligent linkage control of water source extraction, water plant water production, pipeline water transmission, pressurized water delivery, user water use and other links, so as to optimize production dispatching and ensure efficient water supply. During the water plant network dispatching process, pressure measuring devices are needed to monitor the network pressure in real time to detect pressure anomalies and pipe burst accidents in time.

[0003] The existing pressure monitoring of water supply pipe networks mostly adopts the method of pre-installing pressure gauges in the main pipe network, and adopting manual regular inspection and pressure testing monitoring method for branch pipe networks or water supply terminal pipe networks to carry out pipe network inspection and maintenance. The efficiency is low and it is impossible to effectively and timely troubleshoot pressure anomalies in the pipe network. When measuring pressure, the pipe network pressure is usually measured by a water pressure sensor on the pressure measuring device. The existing water pressure sensor is generally directly connected to the pipeline interface. If the liquid flow rate inside the pipeline is too fast, it will impact the water pressure sensor. Long-term impact will cause damage to the water pressure sensor. However, the water pressure sensor is generally directly fixed on the pressure measuring device, and the water pressure sensor cannot be replaced separately, resulting in a short overall life of the pressure measuring device.
