The technical solution adopting is for achieving the above object such: the longitudinal rotary high-pressure metal sealing switch equipment valve mechanism providing has an installation base plate, a side of installation base plate be provided with by rear, in, first three root linkage that hinged fork forms successively, the activity of the front roll bar of linkage is installed on three panel assemblies that are connected with the valve of longitudinal rotary high-pressure metal sealing switch equipment; Opposite side at installation base plate is provided with a fan-shaped drive plate that is driven rotation by isolation circuit breakers by pivot point, on fan-shaped drive plate, have sealing track groove, on the rear fork of linkage, connect a bearing pin that can move in fan-shaped drive plate sealing track groove is housed.In real work, by isolation circuit breakers, drive the fan-shaped drive plate of rotation, and then come drive link mechanism by the sealing track groove on fan-shaped drive plate, the front roll bar ordering about in linkage is realized large span displacement, three panel assemblies that are connected by the valve with longitudinal rotary high-pressure metal sealing switch equipment complete the opening and closing of valve, in the off-position of valve, said mechanism also can complete the locking to valve voluntarily.
Technical solution of the present invention is also: on installation base plate, distribute and be provided with three pivot points, one of them pivot point is used for installing fan-shaped drive plate, and two other pivot point is respectively used to connect rear fork and the front roll bar of load linkage.
Technical solution of the present invention is also: fan-shaped drive plate is provided with and can inserts the rotation central axis of isolation circuit breakers and keep with it concentric rotation locating shaft.
Technical solution of the present invention is also: on the front roll bar of linkage, have a L-type sealing guide groove, three panel assemblies that connect valve are provided with a bearing pin that can move in this L-type sealing guide groove, when longitudinal rotary high-pressure metal sealing switch equipment valve off-position, the bearing pin of three panel assemblies drops in the tail end guide groove of L-type set on connecting rod sealing guide groove valve is locked.
Compared with prior art, the present invention is designed to an independently functional module by the valve mechanism of longitudinal rotary high-pressure metal sealing switch equipment initiatively, and valve is opened, the function that the effective travel of closing and idle stroke and valve have carried out having performance characteristic in the locking of off-position is compound, there is design principle unique novel, compactness rational in infrastructure, function composite performance is reliable, safety simple to operate, cost is low, good manufacturability, parts are few, lightweight, the power stealings such as volume is little, the remarkable advantages such as longitudinal rotary modular switch cabinet design space have sufficiently and reasonably been utilized, product is applicable to the actuating of the horizontal movement valve of the isolation circuit breakers chamber setting in longitudinal rotary high-pressure metal sealing switch equipment.
