Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pressure detection, and more specifically, to a fire pipeline pressure detection device. Background Art

[0002] A fire pipeline pressure detection device is a device used to monitor the pressure of pipelines in a fire protection system, and it is crucial for ensuring the normal operation of the fire protection system. This device is usually installed at the outlet of a fire pump and can display and monitor the pressure status in the pipelines of a fire hydrant system or a sprinkler system in real time.

[0003] Devices for detecting the pressure of fire pipelines usually include pressure sensors installed inside the pipeline (also known as intrusive sensors) and pressure sensors installed outside the pipeline (also known as non-intrusive sensors). Some common fire pipelines usually use intrusive sensors. The probe of an intrusive sensor is usually set inside the pipeline and in direct contact with the medium inside the pipeline. Since the medium contains iron filings or sediment, the medium will damage the probe of the intrusive sensor during the flowing process, thereby affecting the service life of the intrusive sensor and reducing the effect of pressure detection by the intrusive sensor.

Through the setting of the installation groove 3, the installation ring 4 can be installed. The installation ring 4 can support the filter cylinder 5. The filter cylinder 5 is arranged outside the probe of the pressure sensor 2. The probe of the pressure sensor 2 is located inside the pipe body 1 and is in direct contact with the medium. During operation, the medium flowing inside the pipe body 1 will first pass through the filter cylinder 5 and then contact the probe of the pressure sensor 2.

[0028] During the process of the medium flowing from right to left, the medium will pass through the right side of the filter cylinder 5 and discharge from the left side. A large amount of impurities will adhere to the right side of the filter cylinder 5, affecting the working effect of the filter cylinder 5. At this time, during the flow of the medium inside the pipe body 1, the fan blades 7 will drive the mounting rod 6 to rotate. During the rotation of the mounting rod 6, the filter cylinder 5 will be driven to rotate. At this time, the part of the filter cylinder 5 with impurities attached will be located on the left side, and the part of the filter cylinder 5 without impurities attached will move to the right side. At this time, the medium will be filtered by the filter cylinder 5 without impurities attached, and the filtered medium will pass through the filter cylinder 5 in the reverse direction. At this time, the medium can play the role of backwashing and cleaning the filter cylinder 5, achieving the purpose of self-cleaning of the filter cylinder 5, and improving the practicability of the device.

[0035] Please refer to Figure 4 , wherein: two heat conduction plates 12 fixedly connected to the pipe body 1 are inserted through the pipe body 1, and the top of the heat conduction plate 12 is located inside the protective barrel 10.

[0036] In the present utility model, the setting of the heat conduction plate 12 can transfer the temperature of the medium inside the pipe body 1 to the inside of the protective barrel 10, thereby realizing the cooling of the inside of the protective barrel 10 and achieving the effect of dissipating heat from the pressure sensor 2.
