Abstract
The utility model relates to a gradual-open type outside-open hatch door for a manned pressure vessel, comprising a door frame and a sealing door panel. The utility model is characterized in that a turning door frame is arranged on the external side of the sealing door panel, one end of the turning door frame is hinged with one side of the door frame, the central part of the turning door frame is hinged with the external side of the sealing door panel, a connecting slot hole is arranged on the other end of the turning door frame and the connecting slot hole is matched with the locking device of the other side of the door frame installed correspondingly. The utility model has the advantages that: 1. the sealing door panel can turn and open toward one side together with the turning door frame under zero differential pressure, the hatch door of the manned pressure vessel can be opened safely, operator injuries caused by sudden opening of the hatch door are avoided, the operation is convenient and the use is safe; 2. the structure is simple, the performance is reliable, the internal space is greatly saved through the external structure, and the volume of the manned pressure vessel is reduced.
Description
Technical field
The utility model relates to a kind of involute external-open hatch door that is used for manned pressure container.
Background technology
In manned pressure container field, the on-off mode of container hatch door is generally two kinds, the one, " built-in ", the switch that is hatch door is towards manned pressure container inside, adopt the preceence of built-in hatch door to be good seal performance, safety is higher during the release opened door, need take manned pressure container in-to-in usage space but its deficiency is the switch of door.Second kind is " external ", the switch that is hatch door is towards manned pressure container outside, the advantage of external hatch door is to save manned pressure container in-to-in usage space, but owing to there is the inside and outside differential pressure of pressure container, easily produce the problem of safety during the release opened door, can realize the safe locking of hatch door and open by on hatch door, installing mechanical interlocks or gas (liquid) actuation mechanism, but existing mechanical interlock system hatch door complex structure uses operation also convenient inadequately.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, safe in utilization, manned pressure container involute external-open hatch door easy and simple to handle.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Include doorframe and sealing door-plate, its difference is in the arranged outside of sealing door-plate the rotation door frame is arranged, one end of rotation door frame and a side of doorframe are hinged, the centre of rotation door frame is hinged with the sealing door-plate outside, the other end of rotation door frame is provided with the connection slotted eye, and it is matched with the corresponding latching device that is installed in the doorframe opposite side to connect slotted eye.
Press such scheme, described latching device comprises the screw rod that an end and doorframe are hinged, the other end of screw rod configuration handle grip nut, enter the connection slotted eye of rotation door frame at screw rod after, by handle grip nut the rotation door frame is locked, and then sealing door-plate and doorframe are compressed.
Press such scheme, the outside end face of described connection slotted eye is provided with counterbore or the concave station with the nut external diameter phase configuration of handle grip nut, and the degree of depth of counterbore or concave station is 4～8mm.
Press such scheme, described rotation door frame is hinged by free bearing and doorframe one side.
Press such scheme, described sealing door-plate is hinged by free bearing and the rotation door frame of installing in the middle of its outside.
The beneficial effects of the utility model are: 1, when hatch door is opened, unclamp when not throwing off as yet at rotation door frame and latching device, the sealing door-plate is at first thrown off gap of doorframe but can not be opened, can make manned pressure container in-to-in pressure gas quick this moment, fully and safely release, inside and outside differential pressure is eliminated, when latching device is thrown off the rotation door frame, the sealing door-plate can change to a side-sway with the rotation door frame under no pressure differential state reposefully to be opened, realize the safe opening of manned pressure container hatch door, thereby avoid hatch door to throw open injuring the accident of operating personal to take place; Thereby the utlity model has characteristics easy and simple to handle, safe in utilization; 2, simple in structure, dependable performance adopts " external " structure can save a large amount of inner spaces, thereby reduces the volume of manned pressure container.
Description of drawings
Fig. 1 is the constructional drawing of facing of an embodiment of the utility model, and handle grip nut and screw rod are opening.
Fig. 2 is the plan structure figure of an embodiment of the utility model.
Fig. 3 is the partial enlarged drawing of latching device among Fig. 2.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Include doorframe 1 and with the sealing door-plate 2 of its phase configuration, sealing door-plate inner peripheral is installed on sealing band and doorframe end face phase configuration, arranged outside at the sealing door-plate has rotation door frame 4, one end of rotation door frame is hinged by the side of free bearing 3 with doorframe, the centre of rotation door frame is hinged by the free bearing 5 and the sealing door-plate outside, free bearing 5 connects firmly mutually with the centre of sealing door-plate, the other end of rotation door frame is provided with and connects slotted eye 8, connect slotted eye jag laterally, it is matched with the corresponding latching device that is installed in the doorframe opposite side to connect slotted eye, described latching device comprises the screw rod 9 that an end and doorframe free bearing 7 are hinged, the other end configuration handle grip nut 6 of screw rod; The outside end face of described connection slotted eye is provided with counterbore or the concave station 10 with the nut external diameter phase configuration of handle grip nut, the degree of depth of counterbore or concave station is 5mm, enter the connection slotted eye of rotation door frame at screw rod after, by handle grip nut the rotation door frame is locked, and then sealing door-plate and doorframe are compressed.During opened door, unscrew handle grip nut, owing to connect the effect of slotted eye and counterbore, rotation door frame and latching device need handle grip nut to unclamp a segment distance could to throw off, can make manned pressure container in-to-in pressure gas obtain fast, fully and safely release this moment, when continuation release handle jam nut makes itself and screw rod throw off the rotation door frame, can reach the safe opening of hatch door.
