Fixed pipeline sampling instrument

Abstract

The invention discloses a fixed pipeline sampling instrument. The instrument comprises a base box, a power box is installed on the base box, a liquid inlet pipe and a liquid outlet pipe are inserted into the side wall of the base box, a detection pipe is fixedly installed in the base box, and a first piston column and a second piston column are installed in the detection pipe in a sealed and sliding mode. A synchronous rod fixed to the first piston column is installed at the end, close to the first piston column, of the second piston column, a sample feeding pipe, a sample discharging pipe and an assembling pipe are arranged on the side wall of the detection pipe in an inserted mode, and the sample feeding pipe and the sample discharging pipe extend into the liquid outlet pipe. Quantitative sampling is achieved through synchronous movement of double pistons, sample loss can be avoided, electric energy is generated through kinetic energy of fluid, wind energy is generated to achieve heat dissipation, electric energy needed by detection is provided, equipment energy consumption is reduced, the device is more environmentally friendly, conveying of the fluid is not affected when the device is maintained through the assembly type isolation design, and use is more reliable.

Description

technical field [0001] The invention relates to the field of instrument detection, in particular to a fixed pipeline sampling instrument. Background technique [0002] Existing pipeline samplers usually use the method of extraction for sampling and testing, that is, the fluid in the pipeline is pumped into the equipment through valve control and pump for testing, and the sampled fluid is discharged after the testing is completed. If regular multiple sampling will cause a large amount of pipeline fluid It is wasteful, and in the sampling process, an external power supply is required for valve control and pump power. Long-term fixed-frequency sampling will consume a lot of power, and the heat dissipation of the equipment also consumes power, which makes the equipment consume a lot of energy and is not environmentally friendly. When performing maintenance, it is necessary to dismantle the entire device and close the pipeline, which is cumbersome to operate and will cause the fl...
