[0002] At present, all the sealing shells of underwater vehicles and aircraft are usually connected by mechanical methods such as wedge ring connection, clamp connection or bolt connection. The parts of these connection methods are not only manufactured Complicated, difficult to manufacture, high cost, and in the process of assembly, inspection, lake and sea test, when repairing, inspecting and disassembling, the operator has cumbersome procedures, high labor intensity, time-consuming and laborious, and it usually takes tens of minutes to disassemble and assemble a shell. It may cause bumps and damage to the product, resulting in unpredictable losses

Embodiment Construction
[0012] A built-in vacuum valve such as figure 1 , figure 2 As shown, it includes a valve sleeve 2, a valve cover 3, a valve core 4, an orientation pin 5, a limit screw 8, a first retaining ring 9, a first sealing ring 10, a second retaining ring 11, and a second sealing ring 12. The valve sleeve 2 is fixed on the housing 1 through the gasket 6 and the nut 7. The valve sleeve 2 is provided with a valve core 4, the valve cover 3 is arranged on the valve core 4, and the outer wall of the valve core 4 is provided with three annular recesses. groove, each annular groove is provided with a first retaining ring 9 and a first sealing ring 10, an annular groove is respectively provided on the outer wall and the inner wall of the valve sleeve 2, and the second retaining ring 11 and the second sealing ring 12 are provided In the annular groove on the outer wall of the valve sleeve 2, a through hole 13 communicating with the annular groove on the inner wall of the valve sleeve 2 is also...

The invention relates to an internal vacuum valve. The internal vacuum valve is characterized in that a valve sleeve is fixed onto a shell by the aid of a washer and nuts, a valve spool is arranged in the valve sleeve, a valve bonnet is arranged on the valve spool, annular grooves are formed in the outer wall of the valve spool, first retainer rings and first sealing rings are arranged in the annular grooves, another annular groove is formed in the outer wall of the valve sleeve, a second retainer ring and a second sealing ring are arranged in the annular groove in the outer wall of the valve sleeve, a through hole which is communicated with an annular groove in the inner wall of the valve sleeve is further formed in the valve sleeve, and a stop screw penetrates a hole in the bottom of the valve sleeve to be connected with the valve spool. The internal vacuum valve has the advantages that an underwater unmanned submersible vehicle, an aircraft shell and the shell can be effectively connected with one another, the work intensity of operators can be reduced, the assembling, disassembling and detecting time can be shorted, and the work efficiency can be improved; components inside a product can keep in vacuum states for a long time, the cleanness of the components inside the product can be improved, and accordingly the service life of the product can be prolonged.
Description
technical field [0001] The invention relates to a vacuum valve, in particular to a built-in vacuum valve used for connection between shells of underwater unmanned submersibles and aircrafts. Background technique [0002] At present, all the sealing shells of underwater vehicles and aircraft are usually connected by mechanical methods such as wedge ring connection, clamp connection or bolt connection. The parts of these connection methods are not only manufactured Complicated, difficult to manufacture, high cost, and in the process of assembly, inspection, lake and sea test, when repairing, inspecting and disassembling, the operator has cumbersome procedures, high labor intensity, time-consuming and laborious, and it usually takes tens of minutes to disassemble and assemble a shell. It may cause bumps and damage to the product, resulting in unpredictable losses. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome th...
