Description
Technical field
The present invention relates to YE, especially a kind of YE valve position detection device based on the bipotential device.
Background technique
Electric actuator is the terminal actuating equipment in the industrial process control system; It mainly acts on is that control signal with upper computer control system is sent converts corresponding action to; Reach the position of closure member in the control valve or the purpose of other controlling mechanism positions, be widely used in industries such as electric power, metallurgy, petrochemical industry, heat supply, cement, building materials, light textile, food.
Two kinds of conduction potentiometer and incremental encoders take place partly mainly to comprise in the position of the valve position detection device of electric operator at present; Though the conduction potentiometer exist precision lower, can't realize defective such as multi-turn counting,, easy maintenance cheap because of it still is widely used in the electric operator of a lot of models.Adopt that precision is high, the encoder that can realize the multi-turn counting then not only technically difficulty increase greatly, cost has also improved greatly.
Through retrieval, do not find the patent documentation relevant as yet with present patent application.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, provide a kind of two conduction potentiometers of employing and some deceleration gear groups to realize a kind of YE valve position detection device that can enclose counting more.
The objective of the invention is to realize like this:
A kind of YE valve position detection device based on the bipotential device; Low speed part and high speed part by the first conduction potentiometer, the second conduction potentiometer, driving gear, adjusting gear and deceleration gear group constitute; Above-mentioned each parts are coaxial setting; Driving gear and adjusting gear all carry out upper and lower adjustment in the axial direction; The driven gear engagement first conduction potentiometer of driving gear upper end, the coaxial actuation gear that installs of the lower end of driving gear institute receive external impetus and directly engagement drive the high speed part of deceleration gear group, the high speed of deceleration gear group partly meshes the low speed part of driving deceleration gear group; The low speed of deceleration gear group partly meshes the lower end gear that drives adjusting gear, and the upper end gear engagement of adjusting gear drives the second conduction potentiometer.
And the low speed of said deceleration gear group partly is three coaxial gears, and meshes respectively with driving gear and adjusting gear respectively.
Advantage of the present invention and good effect are:
The present invention adopts two conduction potentiometers and some deceleration gear groups to realize that part takes place more for a kind of position that can enclose the valve position detection device of counting, not only can realize many circle countings, has also controlled cost simultaneously effectively.

Embodiment
Be described in detail embodiments of the invention below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
For more clear demonstration protection domain of the present invention, in three accompanying drawings that provide, what provide all is perspective view, and has omitted structures such as mounting plate, but does not influence integral frame of the present invention.
A kind of YE valve position detection device based on the bipotential device; The high speed part 9 and the low speed part 7 of conducting electricity potentiometer 1, driving gear 5, adjusting gear 2 and deceleration gear group by the first conduction potentiometer 3, second constitute; Driving gear through its lower end the coaxial actuation gear that installs 8 receive external impetus; Driving gear rotates through the synchromesh gears 4 that the coaxial driven gear that installs 6 of its top institute directly drives the first conduction potentiometers, thereby realizes that outside transmission and first conducts electricity the synchronous rotation of potentiometer.
The all coaxial setting of above-mentioned each transmission part; Driving gear and adjusting gear all can carry out upper and lower adjustment in the axial direction; The low speed part and the high speed part of deceleration gear group are three coaxial gears in the present embodiment accompanying drawing; And can mesh respectively with driving gear and adjusting gear respectively, the high speed part of deceleration gear group partly is meshed with the low speed of low speed gear group.
The high speed of the actuation gear of driving gear and deceleration gear group partly meshes; The low speed of deceleration gear group part meshes (shown in Figure 1) with the coaxial small gear that installs 10 of high speed part upper end institute of deceleration gear group; The high speed part of small gear and deceleration gear group is rotated synchronously; And the low speed of deceleration gear group part meshes with the lower end gear 11 of adjusting gear; This adjusting gear meshes through its coaxial upper end gear 13 that installs of upper end institute and the second conduction potentiometer institute coaxial driven gear that installs 12 again, like this, second conduct electricity potentiometer rotation be exactly the reduction of speed rotation of external rotating.
Driving gear and adjusting gear are adjusted up and down through it, with select with the deceleration gear group on the gear of different rotating speeds mesh, can realize the effect that different reductions of speed rotate.
Thus; Through the different transmissions position of change adjusting gear with the deceleration gear group; Can realize the kind different rotating speeds combination that two conduction potentiometers are many, for example: the first conduction potentiometer rotates 1 circle, and the second conduction potentiometer can select to rotate 10 circles, 50 circles, 100 circles etc.Because the second conduction potentiometer and external rotating are synchronous, therefore can realize being beneficial to the purpose of the positional information of the first conduction potentiometer to the external rotating record number of turns, finally realized the method that realizes the multi-turn counting under the prerequisite that raises the cost exceeding.
