Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of Electric Actuated Wedge Gate Valves.
Background technique
At present, in the prior art, due to Wedge gate valve wedge shape flashboard to lack corresponding sealing compensation structure between sealing surface of seat, therefore higher to the requirement on machining accuracy of its sealing surface, and in use sealing surface wear is comparatively large, thus greatly shorten the working life of Wedge gate valve.In addition, in existing Wedge gate valve, driving mechanism for actuate valve stem oscilaltion is all directly installed in the end, upper end of valve rod, and in use with valve rod oscilaltion, this just makes the rising of valve rod and driving mechanism to take certain space, if now Wedge gate valve is just arranged on comparatively narrow and small place, a space, just in time has other objects again or above the position of Wedge gate valve installation, then will certainly affect the normal keying of Wedge gate valve, bring inconvenience to user.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, long service life, possess sealing surface automatic compensation function and can not the Electric Actuated Wedge Gate Valves of the occupying volume external space in valve opening and closing process.
For achieving the above object, the utility model provides a kind of Electric Actuated Wedge Gate Valves, comprise valve body, valve gap, valve rod, flashboard, valve seat, described valve gap is installed in valve body top, and the top of described valve body is also provided with a screw, the middle part of described valve rod is provided with one section can form the flank of thread of threaded engagement with described screw, the upper end that described valve rod passes outside valve body is positioned at valve gap, the Vidacare corp of actuatable valve bar oscilaltion is also provided with in described valve gap, described Vidacare corp includes motor, rotating shaft, driving gear, driven gear, described motor and rotating shaft are loaded on also interlock mutually on valve gap, driving gear to be loaded in rotating shaft and to be positioned at valve gap, driven gear to be loaded on upper end that valve rod is positioned at valve gap and to be meshed with driving gear, described flashboard and valve seat are loaded in valve body, described flashboard is by left flashboard, right flashboard, bulb plunger tip, flashboard props up and is configured to, the lower end that the upper end of described flashboard support is positioned at valve body by bearing pin and described valve rod is fixedly connected with, a described left side, right flashboard lays respectively at the flashboard support left and right sides, and it is left, wedge shape outer surface on right flashboard contacts with sealing surface of seat, left, the middle part of right flashboard is passed flashboard support and is movably hinged by bulb plunger tip, left flashboard upper, lower two ends are respectively equipped with left flashboard upper flange and left flashboard lower protruding edge, right flashboard upper, lower two ends are respectively equipped with right flashboard upper flange and right flashboard lower protruding edge, join fixing by upper back-up ring hoop between left flashboard upper flange and right flashboard upper flange, and described upper shield ring sleeve to be loaded on flashboard support and to be fixed by nut axial limiting, join fixing by lower back-up ring hoop between left flashboard lower protruding edge and right flashboard lower protruding edge, and described lower back-up ring is fixed on flashboard support by screw.
The beneficial effects of the utility model are: adopt said structure, because the flashboard described in the utility model is by left flashboard, right flashboard, bulb plunger tip, flashboard props up and is configured to, a described left side, right flashboard lays respectively at the flashboard support left and right sides, and it is left, wedge shape outer surface on right flashboard contacts with sealing surface of seat, left, the middle part of right flashboard is passed flashboard support and is movably hinged by bulb plunger tip, therefore in valve opening and closing process, effect is movably hinged by bulb plunger tip, a left side can be made, wedge shape outer surface on right flashboard can change with the angle of wedge change of sealing surface of seat, realize the auto-compensation effect to sealing surface, and possess the automatic compensation function to sealing surface because of the utility model, therefore the requirement on machining accuracy of valve sealing face is reduced greatly, and in use the wearing and tearing of sealing surface are also reduced greatly, thus effectively extend the whole service life of Wedge gate valve.In addition, because described Vidacare corp includes motor, rotating shaft, driving gear, driven gear, therefore motor output power, drive axis of rotation, and the rotation of rotating shaft rotates by the mating band ovable valve stem of driving gear and driven gear, under the threaded engagement effect of the flank of thread that valve rod is provided with after rotating in the middle and the screw that described valve body top is provided with, valve rod oscilaltion can be impelled, thus realize operating the keying of valve, but the upper end passed outside valve body due to valve rod is positioned at valve gap, and motor only drives rotating shaft rotate and can not impel rotating shaft oscilaltion, therefore described in opening/shutting valve process, valve rod and Vidacare corp can not the occupying volume external spaces.
It is Jiong word shape that the utility model can be set to described valve gap further, its opening end is provided with can install fixing mounting flange end face with valve body top, its top inwall be provided with to downward-extension and with the annular sleeve of described valve rod concentric, the inner ring surface of described annular sleeve offers helical guide groove, the end, upper end of described valve rod is arranged in described annular sleeve, and on the end, upper end of described valve rod also radial being extended with can form with described helical guide groove the projection that rotational slide coordinates.
Adopt said structure, coordinated with the rotary steering of helical guide groove in valve gap annular sleeve by projection on described valve rod, contribute to described Vidacare corp and be better with ovable valve stem oscilaltion to realize valve opening and closing.
