[0050] Example 10:

[0051] This embodiment is optimized based on the above embodiment 1.

[0052] Submersibles face immense water pressure during deep-sea operations, requiring their hatches to possess exceptionally high sealing performance. However, some existing pressure hatches have design flaws and are made of 304 stainless steel, resulting in insufficient sealing performance and poor seawater corrosion resistance, making them prone to leakage in the high-pressure deep-sea environment. Inadequate sealing can directly impact the safety of the submersible, allowing seawater to seep into the hatch, damaging equipment and personnel, and even leading to serious accidents.

[0053] As deep-sea exploration deepens, submersibles are required to withstand higher water pressures. However, the design and use of 304 stainless steel in some existing pressure-resistant hatches are not suitable for deeper waters, resulting in limited pressure resistance. This limited pressure resistance restricts submersibles' operating depths, making them inadequate for deep-sea scientific expeditions and resource exploration. Furthermore, if the pressure limit is exceeded, the hatches may deform or rupture, posing a threat to the safety of the submersible.

[0054] The manufacturing of submersible hatches involves complex material and process challenges. Some existing technologies fail to meet ideal performance requirements due to material and process limitations. For example, titanium alloys offer excellent pressure resistance but are expensive and complex to process, making large-scale production difficult. These material and process limitations hinder the technological advancement and widespread application of submersible hatches. Furthermore, these limitations can lead to unstable product performance or safety risks.

[0055] The door body 1 is made of ZL101A aluminum alloy in one-piece die-casting, which makes the door body 1 have high pressure resistance and low cost, and has good sealing effect.

[0056] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
