Description
Technical field
The utility model relates to sensor technical field, particularly relates to a kind of vacuum transducer device.
Background technology
What existing vacuum alarm field adopted is that sensor adds that decision circuitry is adding the mode of alarm, and there is circuit complexity, sensor cost is high, the problem that development difficulty is large.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of vacuum transducer device, solves the problem that existing vacuum transducer cost is high, development difficulty is large.
The utility model is achieved in that a kind of vacuum transducer device, comprise the piston cylinder of metal, the periphery of piston cylinder is provided with screw thread, the left end of piston cylinder is provided with connected entrance, piston cylinder inside is provided with insulation piston, the left side of insulation piston is provided with the sheet metal do not contacted with piston cylinder, the right side of insulation piston is provided with spring, the left end of spring is connected with sheet metal by insulation piston, the right-hand member of spring is fixed by the right-hand member of insulating mat and piston cylinder, the right-hand member of piston cylinder has air intake opening, the right-hand member of spring is connected with the first wire by piston cylinder right-hand member, piston cylinder is connected with the second wire, the diameter of connected entrance is less than sheet metal diameter.
The utility model tool has the following advantages: whether conveniently can know whether the connected entrance of sensor is in vacuum state, easily, without the need to the circuit of complexity by detecting wire conducting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1, the utility model provides a kind of vacuum transducer device, comprise the piston cylinder 1 of metal, the periphery of piston cylinder is provided with screw thread 2, the left end of piston cylinder is provided with connected entrance 3, piston cylinder inside is provided with insulation piston 4, the left side of insulation piston is provided with the sheet metal 5 do not contacted with piston cylinder, the right side of insulation piston is provided with spring 6, the left end of spring is connected with sheet metal by insulation piston, the right-hand member of spring is fixed by the right-hand member of insulating mat 7 with piston cylinder, the right-hand member of piston cylinder has air intake opening 8, the right-hand member of spring is connected with the first wire 9 by piston cylinder right-hand member, piston cylinder is connected with the second wire 10, the diameter of connected entrance is less than sheet metal diameter.Piston cylinder of the present utility model can be columniform ducted body, and material can be stainless steel, copper, iron etc., and the diameter of spring is less than the internal diameter of piston cylinder.The utility model in use, by screw thread, piston cylinder can be connected with vacuum plant 11 to be measured, when vacuum plant 11 is vacuum, piston left pressure is less than right atrial pressure, and piston can move to the leftmost side, and sheet metal is contacted with piston cylinder, thus make the first wire and the second wire conducting, user can know whether it is vacuum state by the conducting state detecting wire, easily, does not need the circuit of the complexity such as comparator circuit.When vacuum plant leaks gas, then piston can move right under the drive of spring, and sheet metal is not contacted with piston cylinder, thus the first wire and the second wire are disconnected.Namely the gas leakage situation namely can knowing vacuum plant is simply disconnected by wire, easily.Whether the conducting of wire can be in the multimeter of short-circuit detecting shelves by connection one, when wire conducting, multimeter can ring, and proves that vacuum plant is in vacuum state, does not ring and is not namely in vacuum state, easily.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
