Abstract
The invention discloses an ultrahigh pressure flow adjusting device, which comprises equipment such as an air inlet pipe, a high-pressure pneumatic valve, restriction orifice plates, an air outlet pipe, connected pipelines and the like. The air inlet pipe is divided into multiple paths; the paths are sequentially connected with the high-pressure pneumatic valve and the restriction orifice plates through the pipelines, and then the paths of branch pipes are merged into one path of the air outlet pipe. If the number of the restriction orifice plates connected in parallel is a constant n, the through-hole area ratio of the orifice plates is required to be 2n-1:2n-2:...:20, and the flow adjusting accuracy of the system can achieve 1/(2n-1) of the maximum flow. The restriction orifice plates and the pipelines are connected in three connection modes; each connection mode comprises three characteristics of sealing cones, main pipeline through holes and restriction orifices; and cone angles are different along with the difference of the working pressure. The ultrahigh pressure flow adjusting device has the advantages of convenient adjustment of the flow of a high-pressure pipeline within a working pressure range of between 0 and 1,000 MPa, safe and reliable connection and high sealing performance.
Description
Technical field:
The invention belongs to Hydrogen Energy and utilize technical field, the Flow-rate adjustment that this flow regulator is used for the hydrogenation station when giving vehicle-mounted hydrogen storage vessel fast aeration, the temperature effect during with the control inflation guarantees that hydrogen storage vessel is safe in utilization.
Background technique:
Countries in the world are paid close attention to the exploitation of new energy one after another in recent years, and wherein Hydrogen Energy is with plurality of advantages such as its cleaning, pollution-free, efficient height and favored, to the use of Hydrogen Energy in the high pressure mode.Be equivalent to by the process of high-pressure bottle to the low pressure vessel venting when the hydrogenation station inflates for vehicle-mounted hydrogen storage vessel, gas temperature has remarkable rising in the process.This temperature rise phenomenon will cause hydrogen-storage density to reduce, thereby shorten the continual mileage of hydrogen energy automobile, and temperature rise has very big influence to the Security of vehicle-mounted hydrogen storage vessel.Therefore need to regulate the aeration speed of giving vehicle-mounted hydrogen storage vessel,, improve the Security that container uses to weaken the gas-filling temperature effect.
The general pipeline diameter of gas charging system is very little, the pressure superelevation, and conventional flow control valve can't use at all, and the present invention considers to use the mode of restriction orifice parallel connection to carry out the Flow-rate adjustment of pressure duct.
Summary of the invention:
The present invention is a cover high pressure flow controlling device, comprises suction tude, pneumatic high-voltage valve, restriction orifice, steam outlet pipe and the equipment such as pipeline that link to each other, as shown in Figure 1.The suction tude demultiplexing, each road connects pneumatic high-voltage valve and restriction orifice successively by pipeline, and each road arm is merged into steam outlet pipe one road pipeline afterwards.If A
