Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a rapid intake and exhaust dual-function valve for ship airbags. Background Technology

[0002] Inflatable airbags are widely used as core tools in ship launching, transportation, and salvage operations. These airbags generate significant buoyancy or support force through inflation. In this process, the performance of the valves is crucial, directly affecting inflation / deflation efficiency, operational safety, and the lifespan of the airbag itself.

[0003] Currently, most ship airbag valves on the market are simple, single-function intake valves or have simple exhaust structures. They have the following significant drawbacks:

[0004] 1. Low exhaust efficiency: Traditional valve designs prioritize air intake, with exhaust channels often being secondary features and having narrow diameters (typically comparable to the intake port, approximately 0.8mm to several millimeters). When rapid release of high-pressure gas is required, the narrow channel severely restricts gas flow, resulting in excessively long exhaust times. This not only significantly reduces the overall efficiency of ship launching or recovery operations and prolongs the operational window, but may also pose safety hazards in certain emergency situations requiring rapid depressurization.

[0005] 2. Limited functionality and cumbersome operation: The intake and exhaust functions are often not effectively integrated. When performing the "inflation-pressure holding-exhaust" process, operators may need to operate different parts or use additional tools, making the process complex and increasing the difficulty of operation and labor costs.

[0006] 3. Poor durability and high cost: The slow degassing process means that the airbag is maintained under high pressure for an unnecessarily long time. The material is under high stress fatigue for a long time, which accelerates aging and damage and significantly shortens the number of times the airbag can be reused. At the same time, the inefficient operation also indirectly increases the labor and time costs of a single operation.

[0007] Therefore, there is an urgent need in this field for a dual-function valve device that integrates efficient air intake and rapid air exhaust, which can significantly improve operational efficiency, enhance safety, and extend the service life of airbags. Utility Model Content

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0037] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0038] Please see Figure 1-12 A dual-function valve for rapid air intake and exhaust in marine airbags includes a stud 3, a valve core 5, and a valve seat 7. The stud 3 includes a stud fixing plate 301, an air intake 302 located at the upper part of the stud fixing plate 301, and a stud body 303 located at the lower part. A valve core mounting port 304 is provided in the middle of the stud body 303. A central hole 305 is provided in the middle of the valve core mounting port 304. A spring placement platform 306 is provided inside the central hole 305. A screw cap 6 is installed on the periphery of the stud fixing plate 301.

[0039] The valve core 5 passes through the central hole 305 of the stud 3 and is fixed by the spring 9. A sealing ring 4 is provided between the valve core 5 and the stud 302. The valve core 5 includes a valve plate 501, a central column 502, a sleeve 503, a valve cover 504, and a screw 505. The central column 502 is fixedly installed on the top center of the valve plate 501. The sleeve 503 is fitted onto the central column 502. The valve cover 504 is fixedly connected to the center of the central column 502 by the screw 505. The center of both the central column 502 and the valve cover 504 is provided with a through hole with internal threads. After the screw is screwed into the through hole, the central column 502 and the valve cover 504 are fixed. The height of the sleeve 503 is less than the height of the central column 502.

[0040] The valve seat 7 includes a valve seat fixing plate 701, a threaded body 702 located on the upper part of the valve seat fixing plate 701, and an exhaust port located at the lower part. The inner and outer surfaces of the threaded body 702 are respectively provided with an internal thread 703 and an external thread 704. The valve seat 7 is connected to the stud body 302 of the stud 3 through the internal thread 703. The exhaust port includes a side exhaust port 705 and a bottom exhaust port 706.

[0041] The external thread 704 is fixed to a dust cover collar 10 by a threaded ring 8. The dust cover collar 10 is connected to a dust cover 1 and a handle fixing hole 11. The dust cover 1 covers the top of the air inlet 302. A handle 2 is fitted around the outer ring of the air inlet 702. A fixing post 12 is provided at the other end of the handle 2. The fixing post 12 is connected and fixed to the handle fixing hole 11.

[0042] This invention significantly improves exhaust efficiency: During use, the valve core 5 and stud 3 work together, and pressing the valve cover 504 causes the valve plate 501 to move up and down, thus charging and discharging gas. By designing side exhaust ports 705 and bottom exhaust ports 706 on the valve seat 7 as large, rapid exhaust holes, the diameter of the main exhaust channel is dramatically increased from the traditional 0.8mm to the 50mm level, achieving an exponential increase in the exhaust channel area. This greatly reduces the resistance to high-pressure gas flow and drastically accelerates the exhaust speed. The exhaust time of this valve is only one-eighth that of traditional valves (i.e., efficiency increased to 800%), completely solving the long-standing bottleneck problem of slow exhaust in operation.

[0043] This invention significantly extends product lifespan and reduces overall costs: Because the exhaust time is shortened by eight times, the time the internal materials of the airbag are subjected to high-pressure stress is correspondingly reduced, thereby greatly alleviating material fatigue and aging, and effectively preventing damage caused by repeated high-pressure creep. This significantly enhances the reusability of marine airbags, reduces replacement frequency, and lowers long-term operating and maintenance costs for customers.

[0044] This utility model integrates dual functions, offering simple and reliable operation: it integrates high-speed air intake and ultra-fast air exhaust functions into a single valve structure, achieving "one valve for two uses." Operators can easily complete the inflation and deflation operations without replacing parts or using additional tools, simplifying the process and improving operational safety and convenience.

[0045] This utility model features a scientifically designed structure and stable performance: the side exhaust ports 705 and bottom exhaust ports 706, which are distributed in coordination with the center and the four sides, ensure that the air pressure is released evenly and quickly during exhaust, avoiding structural vibration or stress concentration problems that may occur with single-point exhaust, and further ensuring the safety and reliability of the valve itself and the airbag.

[0046] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
