The invention provides a diaphragm capsule inflating and pressure measuring device special for a low-temperature aerospace vehicle. The device comprises a diaphragm capsule, a pressure measuring port,an inflatingport, a support unit, a pressure sensor and an inflatingvalve. The diaphragm capsule is provided with an end face far away from the interior of the diaphragm capsule, and the end face ofthe diaphragm capsule is at least provided with thepressure measuring port, theinflatingportcommunicated with the inner part of the diaphragm capsule, anda first installation base and a second installation base. The support unit is arranged on the end face of the diaphragm capsule and fixedly connected with the first installation base and the second installation base. And the pressure sensor is directly sealed with the pressure measuring port and is fixedly arranged on the first installation base on the end surface of the diaphragm capsule through the supportunit. And the inflatingvalve is directly sealed with the inflatingport and is fixedly arranged on the second installation base on the end surface of the diaphragm capsule through the supportunit. According to the diaphragm capsule inflatingand pressure measuringdevice, the pipeline design can be reduced, the structural layout is optimized, and the problem that a pressure measuringpipeline and an inflatingpipeline are difficult to design is solved.

    本发明提供了一种低温航天运载器专用膜盒充气与测压装置。包括:膜盒,测压口、充气口、支架单元、压力传感器和充气阀。膜盒具有远离膜盒内部的端面,在膜盒的端面上至少设有与膜盒内部连通的测压口和充气口、以及第一安装座和第二安装座。支架单元设置于膜盒端面,并与第一安装座和第二安装座固定连接。压力传感器与测压口密封直接,并通过支架单元固定设置于膜盒端面的第一安装座。充气阀与充气口密封直接,并通过支架单元固定设置于膜盒端面的第二安装座。本发明的膜盒充气与测压装置,可以减少管路设计,优化结构布局,解决了测压管路和充气管路设计难的问题。
