Abstract

The utility model relates to a hydrogen purity analyzer. The hydrogen purity analyzer comprises a chassis, a charging socket, a liquid crystal display and a gas inlet valve are arranged outside the chassis, an intelligent analysis module, a pressure stabilization valve, a needle valve, an electronic flow meter, a hydrogen purity sensor and a constant temperature gas chamber are arranged in the chassis, the hydrogen purity sensor is arranged in the constant temperature gas chamber, a transformer and a rechargeable lithium battery are arranged under the intelligent analysis module, the gas inlet valve is connected with the pressure stabilization valve through a pipeline, the other end of the pressure stabilization valve is connected with the needle valve through the pipeline, the other end of the needle valve is connected with the electronic flow meter through the pipeline, the other end of the electronic flow meter is connected with the hydrogen purity sensor through the pipeline, and the other end of the hydrogen purity sensor is connected with an exhaust port through the pipeline. As hydrogen has stable pressure and the sensor has the temperature compensation function, the detection precision is improved; the constant temperature gas chamber can effectively prevent the drift of the hydrogen purity sensor, thereby having good anti-shock and anti-break effects.

Description

Hydrogen gas purity analysis meter

Technical field

The utility model is a kind of detecting instrument, particularly a kind of hydrogen gas purity analysis meter, and the hydrogen analysis that it is applicable to power generator group hydrogen generator station is applicable to that also the hydrogen purity of ammonia synthesizing industry and battery production technology detects.

Background technology

Existing hydrogen gas purity analysis meter owing to enter the Hydrogen Vapor Pressure instability of instrument, so cause measurement result that deviation is arranged, has influenced the precision that detects; In addition, existing hydrogen gas purity analysis meter is influenced by environmental temperature, makes sensor that drift take place easily, so also directly can have influence on the precision of detection.

Summary of the invention

The purpose of this utility model is in order to overcome the not high defective of precision that existing hydrogen gas purity analysis meter detects, and invents a kind ofly to have voltage stabilizing and prevent that temperature from floating the hydrogen gas purity analysis meter of function.

The purpose of this utility model realizes as follows: described hydrogen gas purity analysis meter, comprise a cabinet, the outside of cabinet is provided with charging socket, LCD and gas admittance valve, be provided with intelligent analysis module in the cabinet, pressure maintaining valve, needle valve, electronic flow-meter, hydrogen purity sensor and constant temperature air chamber, the hydrogen purity sensor is located in the constant temperature air chamber, intelligent analysis module has transformer and chargeable lithium cell, gas admittance valve is connected with pressure maintaining valve by pipeline, the other end of pressure maintaining valve is connected with needle valve by pipeline, the other end of needle valve is connected with electronic flow-meter by pipeline, the other end of electronic flow-meter is connected with the hydrogen purity sensor by pipeline, and the other end of hydrogen purity sensor is connected with exhausr port by pipeline.

Described pressure maintaining valve, needle valve, electronic flow-meter and hydrogen purity sensor be by screw retention on the base plate of cabinet.

Good effect of the present utility model is as follows: the utility model volume is little, and is in light weight, the measuring accuracy height, and good reproducibility, preheating is fast, and response degree rapidly is fast, and maintenance is little, and required verification number of times is few, is fit to execute-in-place; Owing to be provided with pressure maintaining valve, institute is so that the hydrogen that enters in the instrument has pressure stable, so improved the precision of examining side; Because needle valve, pressure maintaining valve, electronic flow-meter and hydrogen purity sensor are to be anchored on the cabinet negative; so just improved the effect of shockproof shatter-resistant greatly; the protection of thermostatic sensor air chamber; the temperature compensation function that sensor itself is arranged again; the effective like this drift that prevents the hydrogen purity sensor has also just improved the precision that detects.
