Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] figure 1 is the schematic diagram of the escape suit inflator.

[0017] Such as figure 1 As shown, the inflation device for the diving suit in this embodiment includes an air source connector 100 , an escape suit connector 200 , an automatic inflation valve 300 , and a manual inflation valve 400 .

[0018] The automatic inflation valve 300 includes two pressure reducers, namely a primary pressure reducer 7 and a secondary pressure reducer 12 .

[0019] The air inlet of the primary pressure reducer 7 communicates with the gas source connector 100, the gas outlet of the primary pressure reducer 7 links to each other with the air inlet of the secondary pressure reducer 12, and the gas outlet of the secondary pressure reducer 12 is connected with the escape port. The air inlet of service joint 200 communicates. The air inlet of the manua...

Abstract

The invention provides a danger escaping diving suit air charging device. The danger escaping diving suit air charging device includes an air source connector, an air inlet of the first pressure reducer communicates with the air source connector, an air outlet of a pressure reducer of a former stage is connected with an air inlet of a pressure reducer of a next stage, and an air outlet of the lastpressure reducer communicates with an air inlet of an danger escaping suit connector; an air inlet of a manual air charging valve communicates with the air source connector, and an air outlet communicates with the air inlet of the danger escaping suit connector; when the manual air charging valve is closed, air source enters the air inlet of the danger escaping suit connector through the pressurereducers from the air source connector; and when the manual air charging valve is opened, the air source directly through the air inlet of the danger escaping suit connector from the air source connector. The danger escaping diving suit air charging device has the advantages that when pressure in a quick floating upward danger escaping unit air bag is lower than environment pressure, an automaticair charging valve can automatically inflate the danger escaping unit air bag; and when large depth danger escaping is carried out, the danger escaping unit air bag can be quickly inflated directly through the manual air charging valve so as to meet the requirements of large inflation flow required by the large depth.

Description

technical field [0001] The invention relates to an inflatable device for an escape diving suit. Background technique [0002] When a diver is in distress underwater, he needs to wear an escape diving suit, enter the rapid pressurization chamber to pressurize to balance with the external water pressure, and then rely on the buoyancy provided by the escape diving suit to leave the rapid pressurization chamber and float to the surface for help. During the pressurization process in the rapid pressurization chamber, it is necessary to inflate the escape diving suit through the inflation device to ensure the diver's normal breathing and prevent the diver's lung barotrauma. At present, the similar devices used abroad are more complex in structure, larger in size and heavier in weight (about 25kg), and have high installation requirements, and cannot be matched with my country's rapid pressurization chamber and escape diving suit. Therefore, how to make the air supply of the inflata...
