Description
Technical field
The utility model relates to valve arrangement technical field, is specifically related to a kind of valve actuator arranging stroke detection mechanism.
Background technique
Valve is in fluid system, be used for controlling the direction of fluid, pressure, flow device be the medium in pipe arrangement and equipment (liquid, gas, powder) is flowed or stops and the device of its flow can be controlled.The purposes of valve is widely, and therefore its role is also very large, and final controlling element is as the indispensable parts of control valve, and final controlling element is actuator in automatic control system and control valve assemblying body.Its effect in automatic control system accepts the signal that self tuning regulator sends, with its position at process pipeline and characteristic, the flow of adjusting process medium, thus by controlled numerical control in the scope required by production process, when existing final controlling element runs, usually judged the aperture of valve by the adjustable height of screw mandrel, not only can not react the aperture of valve intuitively, and precision is also poor, require exquisite system for aperture especially, existing final controlling element can not meet high-precision requirement.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of valve actuator arranging stroke detection mechanism, and the utility model efficiently solves existing final controlling element judges valve aperture by the adjustable height of screw mandrel, and control accuracy is poor, and not problem intuitively.
The utility model is achieved through the following technical solutions:
A kind of valve actuator that stroke detection mechanism is set, comprise final controlling element mounting base (1), mounting base (1) is provided with drive motor (2), display screen (6), drive motor (2) drives adjusting screw (4) positive and negative rotation by driving gear (3), regulate screw mandrel (4) by adjustment screw drive travel(l)ing rest (5) lifting on the body of rod, it is characterized in that: described travel(l)ing rest (5) is provided with stroke detection mechanism (7), described stroke detection mechanism (7) comprises spur rack (71), gear (72) and angle transducer (73), gear (72) and spur rack (71) engagement driving, the central shaft (81) that gear (72) is arranged by fixed support (8) and angle transducer (73) synchronous axial system, angle transducer (73) is electrically connected with display screen (6).
The further Technological improvement plan of the utility model is:
Described gear (72), angle transducer (73) are fixedly connected with A chassis (51) upper surface on travel(l)ing rest (5) top by fixed support (8), and spur rack (71) is fixedly connected with A chassis (51) upper surface by fastening piece (9).
The further Technological improvement plan of the utility model is:
Described travel(l)ing rest (5) is also provided with B chassis (52), C chassis (53), travel(l)ing rest (5) is connected by upper belleville spring group (10) elasticity arranged of C chassis (53) and mounting base (1), B chassis (52) upper surface, lower surface are provided with spacing detecting switch (11), and spacing detecting switch (11) is fixedly connected with mounting base (1) by mounting bracket (12).
The utility model compared with prior art, has following obvious advantage:
One, the utility model is by arranging stroke detection mechanism at travel(l)ing rest top, and by angle transducer, transmission data is directly passed to video terminal, not only significantly improves the intuitive of valve opening data, and improves the control accuracy of valve opening.
Two, the utility model arranges upper and lower spacing detecting switch in the upper and lower part, travel(l)ing rest chassis of existing final controlling element, when travel(l)ing rest runs to specified position under screw mandrel drives, touch corresponding detecting switch, control the keying of motor, not only increase final controlling element control accuracy, extend the working life of final controlling element, and also save the labor intensity of operating personnel.
