Description

一种流体实验水力定量加气装置 A fluid filling devices quantitatively Hydraulic Experiment

技术领域 FIELD

[0001] 本发明涉及流体实验设备,涉及一种流体实验中定量加气的装置。 [0001] The present invention relates to a fluid test device, to a device for the quantitative experiments fluid aerated.

背景技术 Background technique

[0002] 气体流量标准装置是以空气为介质,采用负压法,主要适用于速度式、容积式、差压式及质量流量计等气体流量计的检定、标准、型式评价工作,也可以用于气体流量的测定。 [0002] The gas flow device for the medium is air, negative pressure method is mainly applied to the speed-type, the volume, mass flow meters and differential pressure gas flowmeter calibration, standards, evaluation type, can also be used the determination of gas flow. 气体流量标准装置分为原始标准装置和传递标准装置,原始标准装置是最高标准,原始标准装置分为容积法和质量法两类,又可以称为动态法和静态法。 A gas flow device into a primary standard apparatus and a standard transmission apparatus, the original standard means the highest standard, the original volume of standard methods and apparatus fall into two categories mass method can be called static method and dynamic method. 如容积法中PVTt (压力、容积、温度、时间)法属于静态容积法装置,钟罩式、气体体积管、皂膜式等属于动态容积法装置,其中,钟罩式也可用于静态容积法;质量法中质量时间(Mt)法属于静态质量法。 A volumetric method PVTt (pressure, volume, temperature, time) method is a static volumetric method means Bell, the volume of gas pipes, and other soap film volume method is the dynamic apparatus, wherein the bell-type static volumetric method can also be used ; mass process time mass (Mt) mass method is a static method. 临界流文丘里标准作为气体流量传递标准被广泛采用,美国西南天然气研究院,英国国家工程实验室等都采用此类标准。 Critical flow venturi as a standard gas flow transfer standard is widely adopted, Southwest Gas Research Institute, National Engineering Laboratory, adopted these standards. 德国物理技术研究院采用并联喷嘴的检验工业煤气和其他气体流量。 German Physics Institute of Technology and other industrial gases using the test gas parallel flow nozzle.

[0003]由于气体的逸散性和可压缩性,使得实验室中气体体积的测定比液体更加复杂。 [0003] Because of gas compressibility and escape, so that the volume of gas measured laboratory more complex than the liquid. 体积测定一般采用直接测量法和间接测量法,直接测量法是采用气体流量计进行检测的方法,间接测量法是通过传感器间的结构尺寸间接测定流量值来确定体积的大小。 Assay volume usually by direct measurement and the indirect measurement, used is the method of detecting a gas flow meter measuring direct, indirect measurement is to determine the size of the volume flow rate value measured indirectly between the frame size sensor.

[0004]另外,传统的气体输入装置采用注射式或者喷嘴式两种方式,主要有三个缺点。 [0004] Further, the input device using the conventional gas injection nozzle type or two ways, there are three main drawbacks. 一是气体气密性不足引起测量误差,如普通注射式式加气设备,由于活塞气密性的问题,气体容易从边缘泄露;二是以上两种方式需要的采用体积校准装置进行校准,成本较高;三是若注入气体的试验设备有较高内压时,采用人工加压就会十分困难。 First gas measurement errors caused by insufficient gas tightness, such as the common syringe type refilling apparatus, since the problem of air tightness of the piston, the gas easily leaks from the edges; two or more volumes using two methods require calibration device for calibration, the cost higher; Third, if the gas injection test equipment has a higher internal pressure, intraocular pressure will be very difficult to use.
