Abstract
The utility model relates to a shutter valve tool, in particular to a shutter dropping-proof plate for protecting the shutter. The technical scheme is that a layer of metal plate is arranged in a connecting groove between the upper end of the shutter and a guide screw, wherein, the lower end of the metal plate is folded to form the shape of a groove; two sides of the flute are respectively provided with a lug boss, so the metal plate can be arranged right in a flute at the upper end of the shutter. The shutter valve tool has the advantages of small investment and simple manufacturing; the shutter valve tool is arranged in the groove at the upper end of the shutter, thus preventing direct contact between the shutter and the guide screw, prolonging the service life, avoiding stop production or transportation of the shutter valve due to the dropping of the shutter, preventing a waste of labor and material resources, solving the problem of environment pollution and improving economic benefits.
Description
One, technical field:
The utility model relates to a kind of gate valve instrument, particularly relates to a kind of anti-flake of flashboard that is used for the protection of flashboard.
Two, background technique:
Existing gate valve comprises flashboard, handwheel and leading screw, and wherein, the upper end of flashboard is connected with the lower end of leading screw, and the upper end of leading screw is connected with handwheel.And in use, can cause wearing and tearing owing to contact between flashboard and the leading screw, cause flashboard to come off and make equipment stop production, stop transport, human and material resources have been wasted, even befouling environment, and the cost of a valve arrives several ten thousand yuan at hundreds of, the loss that its damage in equipment operation causes is huge.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, the anti-flake of flashboard that provides a kind of and be used to protect flashboard, avoid flashboard to come off.
Its technological scheme is: be provided with the layer of metal sheet in the flashboard upper end in the groove with being connected of leading screw, described tinsel lower end is folded into groove shapes, and the both sides of groove are respectively equipped with boss, and tinsel can just in time be installed in the groove of flashboard upper end.
Comparatively detailed is that described tinsel is a copper sheet.
The beneficial effects of the utility model are: this product-specific investments is few, make simple, and be installed in the groove of flashboard upper end, completely cut off direct contact the between flashboard and the leading screw, increase working life, stopped gate valve and made equipment stop production, stop transport because flashboard comes off, avoided waste of manpower, material resources, even problem of environment pollution caused, improved economic benefit.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is plan views of the present utility model;
Accompanying drawing 3 is schematic representation that are installed on the gate valve of the present utility model.
Five, embodiment:
1-3 in conjunction with the accompanying drawings, the utility model will be further described:
Its technological scheme is: be provided with flashboard 3, leading screw 4 and handwheel 5 etc. in the gate valve and be prior art, no longer describe in detail, improvements are in existing flashboard 3 upper ends and being connected of leading screw 4 the layer of metal sheet to be installed in the groove, and described tinsel lower end is folded into groove shapes 1, and the both sides of groove are respectively equipped with boss 2, during use, tinsel can be installed in from the side of flashboard in the groove of flashboard upper end, leading screw and flashboard be isolated, wherein by tinsel, tinsel is a copper sheet, plays corrosion-resistant effect.
