Flow detection pipeline structure with pressure-bearing protection mechanism

Abstract

The invention discloses a flow detection pipeline structure with a pressure-bearing protection mechanism, which is characterized in that a flow detector, a detector gas inlet end pressure-bearing protection assembly and a detector gas outlet end pressure-bearing protection assembly form a set of complete flow detection pipeline unit with the pressure-bearing protection mechanism; the pressing force of the pressure relief plugging pressing spring can be overcome by overhigh pressure, the pressure relief plugging base plate is jacked up, and then internal overhigh air flow is discharged through the pressure relief plugging ring platen and the cap pipe pressure relief hole, so that the normal internal pressure is ensured; a telescopic pipe body structure is formed between the pressure-bearing protection end pipeline and the detection meter air inlet end pressure-bearing protection pipeline through a telescopic corrugated pipe, one end of a pushing spring abuts against a first fixed guide end disc, the other end of the pushing spring abuts against a second fixed guide end disc, and a guide straight sliding rod and the second fixed guide end disc slide in a penetrating mode. The linear telescopic adjustability of the length of the pipe body of the pressure-bearing protection assembly at the gas inlet end of the detector facilitates the connection and laying of the pipe bodies.

Description

technical field [0001] The invention belongs to the technical field of flow detection pipelines, and in particular relates to a flow detection pipeline structure with a pressure-bearing protection mechanism. Background technique [0002] The method of catalytic reduction of carbon dioxide to formic acid by electrochemical method in aqueous solution, the reaction principle is that water oxidizes on the anode to generate hydrogen ions and oxygen, and the hydrogen ions migrate to the cathode through the mass transfer process, and participate in carbon dioxide on the cathode The electrocatalytic reduction reaction generates formic acid and side reaction products. [0003] The existing technology has the following problems: the flow meter for the production of formic acid by carbon dioxide electrolysis is an important device for accurately controlling the amount of reactants. A flow detection pipeline structure with a pressure protection mechanism that is safe and safe to use is...
