Description
Technical field
The utility model relates to technical field of valve control, particularly relates to a kind of electric device for valve.
Background technique
The Electric actuator application of current valve widely, no matter be industry, agriculture, national defence is most advanced and sophisticated, or the department such as communications and transportation, people's lives all needs a large amount of, various types of electric valve, especially the explosive media environment such as mine, chemical industry, past intrinsic safety tenminal block designs in independent wire connection cavity, and other tenminal block is at other wire connection cavity, and field connection is very inconvenient with maintenance, especially the situation that at the scene space is less, just more inconvenient.
Summary of the invention
The utility model, in order to overcome the deficiency of above-mentioned technical problem, provides and a kind of intrinsic safety signal terminal and other signal terminal to be designed in a wire connection cavity, structure is simple, volume is little, easy to use.
The technological scheme solved the problems of the technologies described above is as follows:
Electric device for valve, comprise electric device for valve body and wire connection cavity, wire connection cavity is connected with electric device for valve body, patchboard is provided with in described wire connection cavity, patchboard is set with divider wall, patchboard in divider wall is provided with intrinsic safety signal terminal, the patchboard outside divider wall is provided with non-intrinsic safety signal terminal.
Described divider wall adopts nonmetal electrically non-conductive material to make.
Adopt such scheme, due to patchboard being set with divider wall, patchboard in divider wall is provided with intrinsic safety signal terminal, patchboard outside divider wall is provided with non-intrinsic safety signal terminal, therefore intrinsic safety signal terminal is arranged in same wire connection cavity with non-intrinsic safety signal terminal, by the method for divider wall, intrinsic safety signal terminal is separated with non-intrinsic safety signal terminal, meet relative national standards, creep age distance between intrinsic safety tenminal block and non-intrinsic safety tenminal block is more than or equal to the requirement of 50mm, make the structure of electric device for valve simple, volume is little, easy to use.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of electric device for valve two wire connection cavities
Fig. 2 is the utility model structural representation.
Embodiment
As shown in the figure, the electric device for valve of Fig. 1 is provided with intrinsic safety wire connection cavity 1 and non-intrinsic safety wire connection cavity 2, two wire connection cavities are adopted to make the complex structure of electric device for valve, volume is large, use inconvenience, cost is high, the electric device for valve of Fig. 2, comprise electric device for valve body and wire connection cavity 3, wire connection cavity 3 is connected with electric device for valve body, wire connection cavity 3 space is greater than the wire connection cavity of the electric device for valve of employing two wire connection cavities, this can facilitate wiring, patchboard 7 is provided with in wire connection cavity 3, patchboard 7 is set with divider wall 6, divider wall 6 adopts nonmetal electrically non-conductive material to make, the insulating properties of the guaranteed divider wall 6 of energy, ensure that the creep age distance between intrinsic safety signal terminal 5 and non-intrinsic safety tenminal block 4 is more than or equal to 50mm, patchboard 7 in divider wall 6 is provided with intrinsic safety signal terminal 5, patchboard 7 outside divider wall 6 is provided with non-intrinsic safety signal terminal 4, intrinsic safety signal terminal 5 is arranged in same wire connection cavity with non-intrinsic safety signal terminal 4, by the method for divider wall 6, intrinsic safety signal terminal 5 is separated with non-intrinsic safety signal terminal 4, meet relative national standards, creep age distance between intrinsic safety signal terminal 5 and non-intrinsic safety signal terminal 4 is more than or equal to the requirement of 50mm, make the structure of electric device for valve simple, volume is little, easy to use.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model namely openly in scope; still can do some revise or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
Claims (2)
1. electric device for valve, comprise electric device for valve body and wire connection cavity, wire connection cavity is connected with electric device for valve body, it is characterized in that, patchboard is provided with in described wire connection cavity, patchboard is set with divider wall, the patchboard in divider wall is provided with intrinsic safety signal terminal, the patchboard outside divider wall is provided with non-intrinsic safety signal terminal.
2. electric device for valve according to claim 1, is characterized in that, described divider wall adopts nonmetal electrically non-conductive material to make.
