A pressure sensor for pipeline liquid pressure detection

Abstract

The invention discloses a pressure sensor for pipeline liquid pressure detection. The pressure sensor comprises a pipe body, wherein a detachable conduction pipe is fixedly arranged on the upper sideof the pipe body, a detachable sensor body for pressure detection is fixedly arranged at the upper end of the conduction pipe, when the sensor body is mounted or dismounted, the sensor body is dismounted, the wrench is taken down, and one end of the wrench is inserted into the wrench slot, so that the conduction pipe can be wrenched to be locked, fixed or disassembled, and then the sensor body isinserted into the inner side of the upper port of the conduction pipe through the plug to realize fixed installation. The pressure sensor is advantaged in that mounting or dismounting is more convenient, an installation tool does not need to be carried additionally, the film at the lower end of the conduction pipe extrudes the movable rod under the liquid pressure, the movable rod extrudes the film on the upper side so as to conduct the pressure to the detection head to achieve pressure detection, and a problem that detection data accuracy is affected due to the fact that the detection head makes direct contact with liquid and is polluted is solved.

Description

technical field [0001] The invention relates to the technical field of pressure sensors, in particular to a pressure sensor for pipeline liquid pressure detection. Background technique [0002] A pressure sensor is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules, and pressure sensors for pipeline liquid pressure detection are also widely used in pipeline transportation. Realize the real-time monitoring of the hydraulic pressure inside the pipeline to ensure the normal operation of the pipeline. [0003] The applicant of the present invention finds that the existing pressure sensor often needs to be locked and fixed by a wrench when it is installed on the pipeline. In this way, it is necessary to carry specific tools when disassembling or installing the sensor, which is inconvenient to disassemble or install. And when there is liquid inside the pipeline, there will be leakage...
