Document Type and Number:
WIPO Patent Application WO/2022/105036
Kind Code:
A1
Abstract:
The present invention provides a pipeline pressure monitoring device, comprising a housing, a vent nozzle, a first circuit board, a pressure sensor, a sliding sleeve, an elastic member, a magnetic block, a second circuit board, and a position sensor. A first stop block is arranged on the vent nozzle, one end of the vent nozzle protrudes from the housing through a mounting hole of the housing, the pressure sensor is installed at the other end of the vent nozzle, the pressure sensor blocks one end of the vent nozzle, the pressure sensor is installed on the first circuit board, the sliding sleeve is installed in the mounting hole in a sliding manner and sleeved on the vent nozzle, a limit member is arranged on the sliding sleeve, the elastic member is sleeved on the vent nozzle and sandwiched between the first stop block and the sliding sleeve, the magnetic block is installed on the sliding sleeve, the second circuit board is connected to the first circuit board, and the position sensor is installed on the second circuit board and cooperates with the magnetic block so that the signal of the position sensor can change when the sliding sleeve slides. The present invention has simple structure, small size, good smoothness and long life, is not easily damaged, and facilitates the disassembly of the magnetic block.
