Description
Technical field:
The utility model relates to electrical equipment technical field, is specifically related to the unlatching control unit of a kind of transformer with valve.
Background technique:
Transformer is common power equipment, and in order to control its working state, matching used with it is various valves, and these valves are made up of the unlatching control unit of the valve body and the valve body the other end usually.Said unlatching control unit comprises the flange plate that fixedly installs on active rotating disk, positioning disk and the valve body, and initiatively rotating disk and valve body core are fixedly connected, and positioning disk and flange plate are fixedly connected.In order to operate, handle is set to the long single handle of a length usually, makes initiatively dial rotation by pulling handle.The problem that prior art exists is: 1, the installing space of transformer is limited, and valve needs bigger installing space because of the decreased food reason; 2, pipeline is many and situation is complicated around the transformer, and the long handle lateral rotation of stretching out easily is obstructed, and uses inconvenient; 3, handle very easily causes damage because of collision when transportation is installed.
Summary of the invention:
The utility model will provide a kind of unlatching control unit of valve body, with overcome the installing space that prior art exists big, use inconvenient and transportation flimsy problem of handle when installing.
For overcoming the problem that prior art exists, technical solution of the present utility model is: a kind of unlatching control unit of valve body, comprise initiatively rotating disk, positioning disk and flange plate, initiatively rotating disk and valve body core are fixedly connected, its special way is: described active rotating disk is made of the fixing part and a pair of Foldable handle that is symmetricly set in the fixing part outside of centre, and described positioning disk is provided with positioning means.
Above-mentioned positioning means is a positioning disk near the spacing concave surface that is provided with corresponding to the pivot region of Foldable handle on the surface of rotating disk one side initiatively.This is simple for structure, and it is convenient to implement.
Above-mentioned positioning means is the positive stop lug boss that is provided with on the surface of positioning disk near active rotating disk one side.As long as can limit the structure of Foldable handle pivotal position all can adopt.
Above-mentioned Foldable handle comprises horizontal segment and the vertical section that the right angle is hinged, and correspondence is provided with several to symmetrically arranged restraining groove on the edge of positioning disk and flange plate.The vertical section of Foldable handle can be arranged in the restraining groove, to save the space hold area of Foldable handle, plays the effect that limits the pivotal position simultaneously.
Above-mentioned restraining groove comprises two pairs.Because transformer includes only two states of open and close usually, so restraining groove only need limit two end positions and gets final product.
Be provided with retaining member in the above-mentioned restraining groove.When running into vibrations, the vertical section of Foldable handle is not understood outer moving, and especially when the valve upside-down mounting, can guarantee that more the vertical section of handle can not opened automatically.
Above-mentioned retaining member can be jump ring or bump the pearl structure.
Be communicated with on the surface of above-mentioned positioning disk away from active rotating disk one side, with the external port of restraining groove and be provided with retaining member groove is set.Be easy to processing and realize function, and cost is lower.
Compared with prior art, the utility model has the advantages that:
1, easy to use: owing to changed the initiatively structure of rotating disk, handling portion fixing on it has been designed to folding structure, it is long therefore effectively to have reduced handle, has avoided the inflexible problem of rotation that causes because of pipeline more.
Handle was not fragile when 2, transportation was installed: owing to adopted Foldable handle, and the handle of vertical section can be fixed in the restraining groove, therefore guaranteed folding effect, transportation, do not have the problem that causes damage because of collision when installing.
3, installing space is little: owing to reduced the length of handle, therefore can effectively reduce the requirement to installing space.
4, accurate positioning: the utility model utilizes the edge of spacing concave surface as indication, two end points in the open operation, and it is clear to move, and can be well understood to the opening state of valve, and processing ease is avoided misoperation.
