Description
Technical field
The utility model relates to the pad field in water-tight equipment, espespecially a kind of metal jacketed gasket with damage testing function.
Background technique
Pad is in order to more easily damaged when connection between flange, the impaired mechanical presses wearing and tearing come between the corrosion of liquid in pipeline and flange plate, the pad of the prior art all only Packed effect of tool, not there is damaged when detecting it and damaged degree how technology, technician can only judge the life-span of pad according to experimental technology still, sometimes in order to prevent seepage from having to also more intact pad point to be changed, because the workload of the pad that the workload opening inspection is new with changing a slice is about the same, so it is a utilization efficiency that can increase pad and the setting reducing operating cost that the damaged degree of pad can detect.
Summary of the invention
For solving the problem, the utility model provides a kind of metal jacketed gasket with damage testing function, and this apparatus structure is firm, and tightness is good, can measure the damaged degree of pad, uses middle strong operability.
For achieving the above object, the utility model adopts following technology to realize, a kind of metal jacketed gasket with damage testing function, comprise outside fix rubber ring, metal shell, steel wire, mounting hole, rubber layer, metal shell measuring point, steel wire measuring point, wherein rubber layer is the main body of pad, rubber layer is the circle structure that zone line is provided with mounting hole, rubber layer outer edge is provided with around the vertically disposed outside fix rubber ring of rubber layer, rubber layer outer surface is provided with metal shell, the steel wire being parallel to rubber layer upper and lower surface is provided with in rubber layer, steel wire curved arc is also arranged in a crossed manner in rubber layer with other steel wires, steel wire two ends are connected on corresponding steel wire measuring point, steel wire measuring point is positioned at outside fix rubber ring lateral part, steel wire measuring point does not directly contact with metal shell, outside fix rubber ring lateral part arranges first metal shell measuring point, another metal shell measuring point and first metal shell measuring point center of circle are symmetrical arranged.
As further improvement of the utility model, set by described outside fix rubber ring top, metal shell top outer is provided with metal hemming edge, is provided with seal ring mounting groove, is provided with seal ring in seal ring mounting groove between metal hemming edge and the metal shell of its underpart.
As further improvement of the utility model, the coated metal shell of described rubber layer is positioned at the annular distance that rubber layer upper and lower surface central region is provided with spaced through metal shell, is provided with tensioning projection in annular distance.
As further improvement of the utility model, be provided with water-swellable layer in described rubber layer, water-swellable layer is the rubber layer containing palladium powder.
As further improvement of the utility model, steel wire is divided into upper strata steel wire and lower floor's steel wire, and upper strata steel wire and lower floor's steel wire are symmetrically distributed in rubber layer.
Working principle: pad in use there will be corrosion and wearing and tearing, the most directly impact that these corrosion and wearing and tearing bring is exactly the change of the resistance of metal shell and the fracture of steel wire, we use multimeter just directly can obtain the electric current of detection, resistance and voltage, these data just can tell what degree technician's pad has been damaged to intuitively, the need of replacing pad.
The utility model compared with prior art has following beneficial effect:
1, this apparatus structure is firm, and tightness is good, can measure the damaged degree of pad, uses middle strong operability.
