The fixing device comprises a fixing clamp piece 2 and compressing nuts 3 or bolt locks, wherein the fixing clamp piece is provided with lock rod penetrating holes 6. Another technical scheme of the invention is characterized in that the tip at one end of each lock rod is a straight rod, the fixing device comprises a positioning clamp piece 4, a fixing clamp piece 2 and compressing nuts 3 or bolt lock holes 6. The mechanical lock is simple in structure, convenient to operate and high in safety.
Description
Technical field
The present invention relates to a kind of locking device, is specifically a kind of dish-type handle valve mechanical lock.
Background technology
As everyone knows, power plant safety is produced most important.Hydropower Plant operation is frequent, and the number of times of unit regular inspection overhaul is more.By power station electrical production requirement, substantially there is unit regular inspection each week twice, the operation of daily defect elimination processing is also a lot of.Isolation is one of groundwork of our operations staff every day.As the effective isolating points of one, dish-type handle valve, uses more frequent in power station.According to " electric power safety producting rule " regulation, this class valve must be locked.At present, most power stations generally adopt chain to be wound around the mode locking to this class valve to lock.Whenever valve isolated operation, operations staff will carry a large amount of chains and tapered end, not only heavy, returns operation and brings inconvenience, has increased task and has extended the working time.So not single, if the canoe of chain is improper, do not have the object of locking at all, potential safety hazard is apparent.
Summary of the invention
The technical problem to be solved in the present invention is, has defect and deficiency for above-mentioned prior art, provides a kind of simple in structure, easy to operate, the dish-type handle valve mechanical lock that safety is higher.
Technical solution of the present invention is that a kind of dish-type handle valve mechanical lock with following structure is provided.This lock includes a few locking bar and locking bar fastening devices, the termination of described locking bar one end is set to crotch, the other end of described locking bar is provided with screw thread or latch lockhole, be threaded or one end of latch lockhole is fixed on by fastening devices on the valve body of valve, described fastening devices comprises a fixed card and clamp nut or latch lockhole, is provided with locking bar through hole in described fixed card.
Dish-type handle valve mechanical lock of the present invention also has another technical solution, this lock includes a few locking bar and locking bar fastening devices, the termination of described locking bar one end is set to straight-bar, the other end of described locking bar is provided with screw thread or latch lockhole, be threaded or one end of latch lockhole is fixed on by fastening devices on the valve body of valve, described fastening devices comprises a positioning cards and a fixed card and clamp nut or latch lockhole, is provided with locking bar through hole in described positioning cards and fixed card.
Adopt after above structure, compared with prior art, the present invention has simple in structure, easy to operate, the advantage that safety is higher.
As technique scheme supplement and perfect, the present invention also has following feature and advantage:
As preferably, described locking bar is set to three, and described fixed card is set to a triangle, is provided with three locking bars through hole in described triangle fixed card.This structure, is mainly the principle of utilizing triangle to fix the most, and three locking bars form a triangle lock, and it locks more firm and safety.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention one;
Fig. 2 is the structural representation of the embodiment of the present invention two;
In figure: 1, locking bar, 11, crotch, 2, fixed card, 3, nut, 4, positioning cards, 5, latch lockhole, 6, locking bar is through hole, 7, valve handle, 8, valve body.
