A kind of loading and unloading method of double opening and closing hydrogen storage valve

Abstract

The invention relates to an assembling and disassembling method of a double opening and closing hydrogen storage valve. The double opening and closing hydrogen storage valve comprises a valve body, ahand wheel, a first support rod, a second support rod, a cylindrical connecting piece, pawls, a third support rod, a spiral groove, an armature, an electromagnetic coil, a piston, outlets, fan rib channels, one-way valves, a storage part, a fan-shaped closing part, a horizontal groove, a vertical groove and an electronic driving module; the hydrogen storage valve is characterized in that the valveinternally comprises a dual drive module, a double opening and closing module and an abutting joint module; the valve body is provided with the horizontal groove and the vertical groove; the distancebetween the horizontal groove and the vertical groove along the circumferential direction is equal to 1 / 4 of the outer perimeter of the valve body; the assembling method of the whole valve comprisesthe following steps: firstly, installing all the parts in the valve body, then enabling the valve body and the cylindrical connecting piece to be connected into a whole by means of threads, and finally, putting the whole valve into an orifice of a corresponding hydrogen storage tank.

Description

technical field [0001] The invention relates to the field of hydrogen storage, in particular to a method for loading and unloading a double-opening and closing hydrogen storage valve. Background technique [0002] As a new energy source, hydrogen fuel plays an important role. With the reduction of existing gasoline energy sources and the pollution it produces, especially the smog phenomenon that people pay close attention to deeply affects the living standards of residents, the use of new energy sources is inevitable. It must be done; as a green energy, hydrogen fuel has been widely used, such as hydrogen fuel cells have been used in vehicles and other vehicles. [0003] 1.

AI Technical Summary

Problems solved by technology

[0003] 1. In actual use, the storage of hydrogen raw materials is a common technology, that is, hydrogen storage tanks are often used; in use, hydrogen storage valves are required for deflation, and the single-layer opening is relatively thin, such as only setting a one-way The valve or one-layer opening and closing structure is relatively thin; it cannot provide better sealing, stable long-term service life and safe use; and the double-layer opening and closing structure is often more complicated, such as the first air outlet, the second air outlet, etc. Adapted channels are often bent, which increases the difficulty of manufacturing and increases the cost

[0004] 2. In addition, the double-layer opening and closing structure requires double drives. If an additional manual emergency drive is added, it will become three drives. The structure is complicated and the cost is high

[0005] 3. The drive structure in the prior art often occupies a large size, which brings inconvenience to installation and adaptation, and increases the cost. Especially important, the existing technology in the hydrogen storage valve cannot add additional manual emergency in addition to the main drive drive

[0006] 4. The threaded installation structure in the prior art is simple and light, but after long-term use, it is easy to loose the thread, and the ordinary connection is not a big problem; but for the high-pressure storage tank, the loose threaded connection means leakage, and the gasket is also difficult. Mates with threads, so there is no good solution in the prior art

[0007] 5. The hydrogen storage valve in the prior art has only one external pipeline, that is, only one final outlet, which is difficult to adapt to the needs of multiple working conditions, and cannot achieve a better pressure relief effect
