Description

Technical Field

[0001] The utility model relates to the field of fire-fighting facilities, and particularly relates to an installation structure of a pressure sensor in a fire-fighting water supply pipeline. Background Technique

[0002] Strengthening the usual maintenance inspection and monitoring management of the fire-fighting water supply system is a meaningful task. Especially with the development of the Internet of Things technology for fire-fighting facilities, it is particularly important to strengthen the automatic detection and monitoring of pressure, one of the important design parameters, in the fire-fighting water supply system, and to transmit the sensed information data to the fire control center in a timely manner.

[0003] In the fire-fighting water supply system, the sensing data acquisition of the Internet of Things system for fire-fighting facilities requires pressure sensors to be installed on the outlet pipe of the fire pump, the municipal inlet pipe, the outdoor fire hydrant pipe network, etc., to understand the pressure state of the system in real time.

[0004] The installation and maintenance management directly affect the operation of the original fire-fighting water supply system. The replacement and repair of the pressure sensor require shutting off the water supply of this section of the fire-fighting water supply pipeline. After shutting off the water supply of the fire-fighting water supply pipeline, the fire sprinkler system cannot work properly. If a fire occurs at this time, the consequences will be unimaginable, affecting a certain safety function of the original fire-fighting facilities and reducing the reliability of the original fire-fighting water supply system. For this reason, an installation structure of a pressure sensor in a fire-fighting water supply pipeline is proposed. Content of the Utility Model
