Wherein, the spherical plate that described door-plate is outwardly convex.Described retaining mechanism comprises the second axle sleeve, the second axle sleeve is fixed on described door-plate, the second rotating shaft is arranged in the second axle sleeve, all stretch out outside the second axle sleeve at the two ends of the second rotating shaft, handle is arranged on external part on it, on lower external part, dead bolt and handle are arranged, on the inwall of short cylinder, be fixed with snap close, under locking state, snap close is corresponding with the position of dead bolt.There is joint ring the edge, lower surface of described door-plate, on the door-plate of joint ring inboard, is fixed with for supporting the support ring of joint ring.
The further improvement of the utility model scheme is that described door-plate center has glass window, thereby makes personnel in cabin to observe situation out of my cabin by this glass window.
Take such scheme, have the following advantages:
Because naval vessel of the present utility model overlaps pivoted loop is arranged at door-plate with as the short cylinder outside of doorframe with withstand voltage watertight circle door, being axial restraint between pivoted loop and short cylinder coordinates, radially rotatable shape coordinates, and in passing through between pivoted loop and door-plate, the outer lug boss chucking, utilize the first rotating shaft and the gear in the short cylinder outside, the arc-shaped rack in the pivoted loop outside, can control pivoted loop rotates, thereby realize the lock sealing (its principle is similar to the hermetically-sealed construction of the autoclave used in daily life) of door-plate and short cylinder surrounding, make the sealing performance of this watertight circle door greatly improve.Simultaneously, after this watertight circle door has been manufactured, can carry out hydraulic pressure to it is 10Kg/cm
2Interior pressure test and hydraulic pressure that (about 1MPa), time are 5 minutes are 20Kg/cm
2The external pressure test that (about 2MPa), time are 15 minutes, as leakproof, crackle or permanent deformation, be qualified products after test.This watertight circle door can all carry out inside and outside hydraulic test before use, guarantees that it has qualified withstand voltage properties, thereby reduces the potential safety hazard existed in the later stage use.
