The diaphragm sealing and clamping assembly mainly realizes the separation of gas and liquid in the falling pressure type diaphragm storage tank and meets the requirement of the supply of 'zero gas inclusion' degassed deionized water in a liquid cavity. Meanwhile, the liquid in the storage tank is ensured not to be influenced by mechanical environments such as acceleration and the like in the high-speed flying process, and the real-time high-discharge-efficiency discharge can be met. The structure design of the device needs to solve the problem of high-quality sealing in the storage tank and real-time high-efficiency supply in a high-speed state, and overcomes the defects of low discharge efficiency, poor sealing property and large welding heat influence in the traditional design.

The difficulty lies in that: firstly, the system has high requirements on discharged liquid, the liquid cavity is required to be degassed deionized water with zero gas inclusion, certain risks and technical problems exist in the sealing performance of the isolation interface, the higher requirements are provided for the sealing performance of the diaphragm clamping assembly serving as the gas-liquid isolation interface, and the gas in the gas cavity is not allowed to permeate into the liquid cavity. And secondly, the shell of the falling-pressure type diaphragm storage tank is an ultra-thin-wall shell (the wall thickness is 0.4mm), the air cavity shell, the diaphragm clamping assembly and the liquid cavity shell are formed by welding, the gas-liquid cavity isolation interface belongs to contact between a non-metal material and a metal material, high-temperature heat can be generated in the welding process, rubber at the sealing position is easily heated and damaged to cause adhesion through the heat conduction effect of the metal clamping structure, the technical problem that high temperature is easily damaged exists, and high-efficiency sealing cannot be realized. The falling-pressure type diaphragm storage tank needs to be subjected to various severe environment tests in a high-speed flying environment, and meanwhile, the deionized water is supplied in a multidimensional state in real time, so that the technical problems of flow limitation, stagnation, flow blocking and the like easily caused by the influence of a dynamic environment in multidimensional high-speed and real-time supply exist, on one hand, the flow rate is not allowed to be influenced in the supply process, and on the other hand, the high-discharge-efficiency discharge of the storage tank is ensured.

The three technical problems of adhesion of rubber sealing contact points and high liquid cavity discharge efficiency under multi-dimensional high-speed flight caused by welding high-temperature thermal stress are solved, the novel design of the diaphragm sealing clamping assembly capable of realizing real-time high-efficiency discharge of the storage box in an ultra-low pressure acceleration environment is realized by adopting an ultra-thin ultra-soft multi-edge diaphragm design structure (the discharge efficiency reaches more than 99 percent), stable overturning of the rubber diaphragm 5 in the acceleration operation environment is realized, mass center deviation in liquid discharge is avoided, and convenience is provided for accurate control of flight attitude of a small aircraft. The adoption of the diaphragm material butyl rubber with better service life and performance reduces gas permeation, realizes zero gas inclusion sealing isolation and ensures the supply of degassed deionized water.
