Abstract

The invention relates to the field of valves, in particular to a lightweight pressure reduction hydrogen supply device suitable for a hydrogen energy handheld torch. The invention provides a lightweight pressure-reducing hydrogen supply device suitable for a hydrogen energy handheld torch. The lightweight pressure-reducing hydrogen supply device comprises a bottleneck valve, a pressure reducing valve, a switch assembly, an ejector pin, a small spring and a gas cylinder cap. A gas cylinder and a combustor in a hydrogen energy handheld torch combustion system are connected in series through the light-weight pressure reduction hydrogen supply device, the light-weight pressure reduction hydrogen supply device is responsible for gas cylinder opening and closing, high-pressure hydrogen pressure reduction and hydrogen sealing, the problems of large-pressure-reduction-ratio pressure reduction, high-reliability sealing, low opening and closing torque and the like are solved, and the light-weight pressure reduction hydrogen supply device has the advantages of being wide in temperature range, miniaturized and light in weight.

Description

technical field [0001] The invention relates to the field of valves, in particular to a lightweight decompression hydrogen supply device suitable for a hydrogen energy hand-held torch. Background technique [0002] In various large-scale events, it is often necessary to use a hand-held torch to pass the fire. Since the process of torch passing is carried out outdoors, the external environment has a great influence on the burning of the torch. At present, the torch fuel used at home and abroad is mainly propane. The propane liquid is gasified in the gas cylinder, and the propane gas is supplied to the burner. During the use process, there are problems of low temperature resistance, poor wind resistance and rain resistance. It is easy to cause the torch to go out. [0003] With the phased goal of carbon peaking and carbon neutrality proposed by my country, hydrogen is the cleanest energy source today, and the combustion product is only water, which is one of the cleanest ener...
