The invention relates to a pressure regulating integration device used for an air starter. The device is mainly composed of a pressure regulating device shell, a plug assembly, a pressure adjusting device, an adjusting screw, a pressure adjusting device spring, a pressure adjusting device rod and the like; the device is mainly suitable for a power system of a flying device, when the inlet pressureranges from 207 kPa to 503 kPa, and the highest temperature is 250 DEG C, the air flow pressure on an outlet is adjusted and is kept stable, meanwhile, through the adjusting screw, the outlet pressure target value can be subject to fine adjustment, and needed requirements are met; when the device is switched to be free of work, the pressure can be rapidly released, device safety and reliability are ensured. The device can provide a stable air source for the air starter, the structure is simple, maintaining is easy, the cost is low, the pressure adjusting speed is high, meanwhile, the work temperature range is wide, and the large actual application value is achieved.
Description
technical field [0001] The invention belongs to the technical field of power systems, and relates to a pressure regulating integrated device for an air starter. Background technique [0002] The air starter is needed when the aircraft engine is started on the ground. The air pressure at the inlet of the existing air starter has a strict input range, so it is necessary to install a pressure regulating device in front of the starter to adjust the high-pressure gas pressure to the available range of the air starter. . The existing pressure regulation device has many modules, low integration and large volume, which increases the weight of the machine, and the response of pressure regulation is slow, which has a great impact on the feedback speed of the power system, and the requirements for working conditions are relatively harsh. Contents of the invention [0003] The object of the present invention is to provide a pressure regulation integrated device with short pressure re...
