Description
Technical field
The invention belongs to the pressure vessel technology field, be specifically related to a kind of cover locking framework of horizontal pressure vessel
Background technique
so-called cover locking framework is meant the mechanism of cover lock on cylindrical shell with pressurized container; In patent documentation, can be seen in the cover locking framework; " fast opening and closing mechanism of pressurized container " typically recommended like publication number CN1865736A, this patent application is proposed on June 9th, 2006 by the applicant.
above-mentioned patent application scheme has overcome the deficiency of CN1512090A (pressurized container with quick acting switching mechanism) objectively, has embodied the 4th page of the 4th section alleged technique effect of specification.
still; Because the technological scheme that above-mentioned CN1865736A recommends is to vertical pressure vessel; Thereby be difficult to even can't migrate to horizontal pressure vessel, particularly, if this related cover locking framework of fast opening and closing mechanism that is applicable to vertical pressure vessel is applied to horizontal compressive force container; So following technology barrier can appear: one of which; Receiving space constraints, no matter because be under the state of unlatching or closing cap, is that connecting base, screw rod and the handwheel of carrier can produce interference phenomenon near object with the lid; Its two, slow to the keying speed of lid, no matter because be lid to be opened or closed all need make screw motion, drive the connecting base with the lid solid welding by screw rod through operation to handwheel, lid separated with pressurized container or cooperate; Its three, complicated integral structure and cause making, install and use trouble.
in addition; Owing to have pressure usually in the cylindrical shell of pressurized container; If the pressure in the cylindrical shell is not discharged and the unlatching cover, can cause safety problem so, for example when pressurized container is natural gas filter; If giving earlier by vent, the rock gas with pressure in the cylindrical shell do not get rid of and when opening cover, then dangerous and harmfulness is bigger.
In view of above-mentioned prior art, the applicant has done rationally to improve targetedly, and the technological scheme that will introduce below produces under this background
