Problems solved by technology
[0003] The purpose of the present invention is to solve the problem of excessive structural size and length of the existing series-type gas generating device. A double-pulse gas generating device with a parallel combustion chamber structure disclosed by the present invention can greatly improve the use efficiency of the housing space. At the same time, the relatively independent combustion chamber structure can manufacture products with different charge contents to meet the requirements for the use of different gas quantities

Embodiment 1
[0020] The double-pulse gas generating device with a parallel combustion chamber structure in this embodiment adopts a parallel arrangement, and the central area and the peripheral area respectively constitute two relatively independent combustion chamber structures. Including: shell 1, peripheral ignition device 2, central ignition device 3, central charge 4, peripheral charge 5, peripheral nozzle 6, central nozzle 7, spacer 8, end cover 9. The central axis on the left side of the housing 1 is provided with 3 threaded holes for installing the central ignition device, and the left side of the housing 1 is provided with 3 threaded holes for installing the peripheral ignition device. Connected threaded holes, the left side of the housing 1 is adapted to the shape of the end cover 9 connected by welding. The center charge 4 is a cylindrical charge hollowed out in the middle. The peripheral charge 5 is a hollowed-out cylindrical charge, and the inner diameter of the peripheral ch...

The invention belongs to the field of gasifiers and discloses a double-pulse gasifier with parallel combustion chamber structures. By means of parallel arrangement, the two relatively independent combustion chamber structures are formed in a center area and a peripheral area respectively. The double-pulse gasifier with the parallel combustion chamber structures comprises a shell, a peripheral ignition device, a center ignition device, a center propellant, a peripheral propellant, a peripheral nozzle, a spacer bush and an end cover. The invention further discloses mounting and using methods of the double-pulse gasifier with the parallel combustion chamber structures. Due to structural parallel arrangement, the double-pulse gasifier with the parallel combustion chamber structures has the advantages that firstly, on equal conditions, the gasifier is spatially shortened in length, and space utilization efficiency of the shell of the gasifier is improved; secondly, continuous twice ignition in specified interval time can be realized to meet the utilization requirement on generation of required fuel gas in specific time interval; thirdly, products different in propellant content can be made in the two combustion chambers to meet the utilization requirement on different volumes of required fuel gas.
Description
technical field [0001] The invention relates to a double-pulse gas generating device with a parallel combustion chamber structure and installation and use methods thereof, belonging to the field of gas generators. Background technique [0002] At present, most of the gas generating devices on the market are single-pulse operation, that is, the gas generator is completed after the first ignition to produce gas, and the gas generator must be disassembled after the second ignition to produce gas, and then reloaded. (propellant), so for some special cases that need to provide gas at a specific time interval, it is not satisfactory; therefore, it is a problem to be solved urgently for a gas generator to be able to continuously provide two gas at a certain time interval in a gas generator. Therefore, someone proposes a controllable multi-pulse gas generator (patent publication number: CN102080528A) in series. Under the condition that the overall structural size of the generator i...
