Abstract
The utility model discloses a disc lock with a visual function, which comprises an upper shell and a lower shell, wherein the upper shell is provided with a first lock hole; a core body is arranged in the upper shell; a semicircular groove is formed in the middle of the front end of the lower shell, a main rotating block is arranged in the middle of the front end of the upper shell, and a secondary rotating block is arranged in the middle of the front end of the core body; the core body is rotationally connected with the upper shell, and the upper shell is rotationally connected with the lower shell; go up evenly distributed polylith main stop on the casing, evenly distributed polylith secondary stop on the core, main stop and the corresponding crisscross distribution of secondary stop. According to the disc valve, the core body, the upper shell and the lower shell are sequentially sleeved on the disc valve, and the main stop block of the upper shell and the secondary stop block on the core body are matched and arranged at intervals, so that the core body can be opened and closed in a state that the main stop block and the secondary stop block are changed to be overlapped or not through the relative rotation of the core body and the upper shell, and personnel can conveniently judge the opening and closing conditions and whether the valve is completely closed or not through direct observation.
Description
Technical Field
The utility model relates to a disc valve, in particular to a disc lock with a visual function.
Background
In the operation process of the hydropower station, the question of whether the isolation measures of field workers to the operators are reliable or not can be generated. Especially, many valves of the hydropower station are disc valves, and the opening and closing state of the valves and whether the valves are completely closed cannot be simply and effectively judged through a common disc valve lock, so that potential safety hazards exist.
Therefore, the existing latch used for the disc valve has the problem that the opening and closing state of the valve cannot be intuitively judged.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a disc lock with a visual function. The utility model has the advantage that the open-close condition of the valve can be visually judged to eliminate potential safety hazards.
The technical scheme of the utility model is as follows: a disc lock with a visual function comprises an upper shell and a lower shell which are semicircular and mutually correspond; the upper shell is internally provided with corresponding semicircular core bodies; the inner size of the lower shell corresponds to the outer size of the upper shell, and the inner size of the upper shell corresponds to the outer size of the core; a semicircular groove is formed in the middle of the front end of the lower shell, a main rotating block corresponding to the semicircular groove is arranged in the middle of the front end of the upper shell, and a secondary rotating block corresponding to the main rotating block is arranged in the middle of the front end of the core; the core body is rotationally connected with the upper shell, and the upper shell is rotationally connected with the lower shell; a plurality of main stop blocks are uniformly distributed on the upper shell, a plurality of secondary stop blocks are uniformly distributed on the core body, and the main stop blocks and the secondary stop blocks are correspondingly and alternately distributed.
In the disk lock with a visual function, the middle part of the front end of the core body and the middle part of the front end of the upper shell are both provided with the knobs.
In the above disc lock with visual function, the middle parts of the outer edges of the upper shell and the lower shell are provided with corresponding protruding grooves.
In the disc lock with the visual function, the right sides of the upper shell and the lower shell are both provided with corresponding mechanical locking blocks; and each mechanical locking block is provided with locking holes which are uniformly distributed.
Compared with the prior art, the disc valve is sequentially sleeved with the core body, the upper shell and the lower shell, and the main stop block of the upper shell and the secondary stop block on the core body are matched and arranged at intervals, so that the core body can be opened and closed by changing the state of whether the main stop block and the secondary stop block are overlapped or not through the relative rotation of the core body and the upper shell, personnel can conveniently judge the opening and closing state and whether the valve is completely closed or not through direct observation, and the disc valve is more convenient to use compared with an original disc valve door lock; the visual function is realized through adding mutually supporting of establishing core and last casing, and the inspection operation in the convenient maintenance can be under the prerequisite of not opening disc valve lock, just can directly see the situation of valve before relevant operation to can just can inspect the isolation measure before the work and whether target in place, its is more practical and convenient.
Therefore, the utility model has the advantage that the open-close condition of the valve can be visually judged to eliminate potential safety hazards.
Furthermore, the core body and the upper shell are both provided with knobs, so that the rotation is convenient;
through set up corresponding mechanical locking piece respectively on last casing and the casing down to set up the lockhole on mechanical locking piece, can realize going up casing and down casing and disc valve's firm combination through adding at mechanical locking piece and establishing the safety lock etc. and improve the security.
