An electronically controlled dual-drive hydrogen storage valve

Abstract

An electronic control dual-drive hydrogen storage valve comprises a valve body, hand wheels, a first support rod, a second support rod, a cylindrical connector, pawls, a third support rod, a spiral groove, an armature, electromagnetic coils, a piston, outlets, fan rib channels, one-way valves, a storage portion, a fan-shaped sealing portion, a cross groove, a vertical groove and an electronic drive module. A dual-drive module, a dual-on-off module and a butt joint module are arranged in the valve. The cross groove and the vertical groove are formed in the valve body. The circumferential distance between the two grooves is equal to one fourth of the outer circumference of the valve body. The electronic drive module comprises a capacitor, a resistor, a relay, contacts Al and A2 and a power source. One end of the power source is connected with the electromagnetic coils of the hydrogen storage valve, and the other end of the power source is connected with an on-off circuit. In the on-off circuit, the contacts A1 and A2 are connected or disconnected so that the circuit is closed or opened. The relay is connected with the capacitor in parallel. The resistor is connected with the relay inseries.

Description

technical field [0001] The invention relates to the field of hydrogen storage, in particular to an electronically controlled double-drive 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

[0008] 6. The electric control valve in the prior art consumes a lot of power and lacks safety protection
