Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0028] from figure 1 It can be seen that the injector of the present invention mainly includes a top cover 3, an injection plate 1 and a flange 2, the top cover 3 is provided with a first working fluid inlet nozzle 4, and the flange 2 is provided with a second working fluid inlet nozzle 4. The fluid inlet nozzle 5, the top cover 3, the injection plate 1, the flange plate 2, the first working fluid inlet nozzle 4, and the second working fluid inlet nozzle 5 are integral welding structures. The center of the top cover 3 and the injector plate 1 is provided with an ignition channel 12 that penetrates up and down, and is ignited by a firearm specially arranged in the center. The igniter can be a torch igniter, a plasma igniter, an electric igniter, etc.
[0029] In this embodiment, the first working fluid is liquid oxygen, the second working fluid...

The invention relates to a liquid-propelled fuel gas generator jetting-injecting device, in particular to a high-reliability integrated jetting-injecting device, and the high-reliability integrated jetting-injecting device can be taken as a combustion adjacent component of combustion devices taking liquid oxygen and alcohol as working substance and is also applied to the combustion devices takingother fuels as the working substance. The jetting-injecting device comprises the components of a jetting-injecting disc, a flange disc, a top cover, an oxidizing agent inlet pipe mouth, a fuel inlet pipe mouth and the like, the center of the jetting-injecting device is provided with an ignition passage, ignition is performed by an igniter arranged in the center of the head portion of the jetting-injecting device, the jetting-injecting disc and the flange disc form a fuel cavity, the jetting-injecting disc and the top cover form an oxidizing agent cavity, an oxidizing agent and the fuel enter the oxidizing agent cavity and the fuel cavity correspondingly through the oxidizing agent inlet pipe mouth arranged in the top cover and the fuel inlet pipe mouth arranged in the flange disc correspondingly and enter a combustion chamber to be subjected to combustion through flow passages and jetting-injecting units arranged in the jetting-injecting disc, and the required high temperature fuel gasis generated. By means of the high-reliability integrated jetting-injecting device, the problems that a traditional multi-nozzle brazing jetting-injecting device is high in cost and poor in reliability are solved.
Description
technical field [0001] The present invention relates to a liquid-propelled gas generator injector, in particular to a highly reliable integral injector, which can be used as a combustion component of a combustion device using liquid oxygen alcohol as a working medium, and can also be used in other fuels. Working fluid combustion device. Background technique [0002] When the high-altitude engine is tested on the ground, it is usually necessary to place the engine in a sealed cabin, and use a vacuum ejector to keep the outlet of the nozzle in the sealed cabin at a low pressure state during the working process of the engine to ensure that the nozzle is full. The ejector needs water vapor as the ejection working medium. When a certain type of engine is tested on the ground, it is necessary to provide water vapor with a temperature of 250°C, a pressure of 2MPa, and a mass flow rate of 80t / h. For example, if the traditional multi-nozzle brazing injector scheme is used for the s...
