Abstract
The utility model relates to a positioning device for an electric control valve, and the positioning device for the electric control valve is characterized by comprising a circuit board, a positioning plate, an optoelectronic switch and an output shaft. The positioning device coaxially arranged on the output shaft. The circuit board is arranged on the output shaft on the lower portion of an opening of the positioning device in the radial direction. The optoelectronic switch is arranged on the circuit board and corresponds to the outer edge of the positioning plate.. When the positioning plate is rotating, a groove which is arranged on the outer edge of the positioning plate generates signals through the optoelectronic switch. An annular inner ring is coaxially arranged in the outer edge of the positioning plate. An inner ring groove is arranged on the annular inner ring. An inner ring optoelectronic switch is installed on the circuit board corresponding to annular inner ring. When the positioning plate is rotated, the inner ring groove generates signals through the inner ring optoelectronic switch. The positioning device for the electric control valve has the advantages of effectively improving the positional accuracy of the electric control valve and prolonging service life, thereby improving reliability of the electric control valve.
Description
Technical field
The utility model belongs to the mortor operated valve technical field, especially a kind of electric control valve positioning device.
Background technique
The positioning device of existing electric control valve comprises output shaft and rotational potentiometer, and its orientation type is: output shaft driven rotary potentiometer shaft rotates, and produces thus different voltage signals, reaches the purpose of electric control valve location determination.
This positioning device is to realize by the regulating action of variable resistor to voltage, thereby therefore can cause that the factors of resistance change can cause the variation of resistance value to affect the Location accuracy of electric control valve; Secondly, the brush of rotational potentiometer and resistance body are in contact condition constantly, because both long-term rubbing actions, the one, thus can cause the wearing and tearing of potentiometer to affect Location accuracy, can cause electric control valve to be scrapped because losing stationkeeping ability owing to work long hours in addition, reduced the working life of electric control valve, and rotational potentiometer exists limited, service condition requirement height mechanical life, the complicated shortcomings that waits of control circuit.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and simple in structure, long service life, a kind of electric control valve positioning device that Location accuracy is high are provided.
Technical solutions of the utility model are achieved in that
A kind of electric control valve positioning device, it is characterized in that: comprise circuit board, positioning disk, optoelectronic switch, output shaft, the coaxial output shaft that is fixedly mounted with of described positioning disk, output shaft below the positioning disk opening radially is equipped with circuit board, corresponding positioning disk outer rim is shaped with optoelectronic switch on circuit board, thereby the groove that its outer rim was shaped with when described positioning disk rotated produces signal by described optoelectronic switch.
And, coaxial being shaped with in the ring-type encircled in the outer rim of described positioning disk, be shaped with outer annular recess on the ring in the described ring-type, the circuit board that encircles in corresponding ring-type is equipped with interior ring optoelectronic switch, thereby outer annular recess produced signal by described interior ring optoelectronic switch when described positioning disk rotated.
And described optoelectronic switch is two, is the setting of mirror image horizontal symmetrical.
And described interior ring optoelectronic switch is two, is mirror image and vertically is symmetrical arranged.
Advantage of the present utility model and good effect are:
1, this device adopts at positioning disk and makes the purpose that mode that some grooves are combined with optoelectronic switch realizes the electric control valve location determination, has effectively avoided because traditional rotational potentiometer wearing and tearing cause the problem of electric control valve Location accuracy weak point in low and working life.
2, the utility model design science is reasonable, and is simple in structure, Effective Raise the Location accuracy of electric control valve, prolonged working life, thereby promoted the reliability of electric control valve.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the structural representation of the utility model positioning disk.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of electric control valve positioning device, as shown in Figure 1 and Figure 2, comprise circuit board 1, positioning disk 2, optoelectronic switch 3, output shaft 5, the coaxial output shaft that is fixedly mounted with of described positioning disk, output shaft below the positioning disk opening radially is equipped with circuit board, corresponding positioning disk outer rim horizon glass picture symmetry is shaped with two optoelectronic switches on circuit board, thereby five grooves 4 that its outer rim was shaped with when described positioning disk rotated produce signal by described optoelectronic switch.
In the present embodiment, in order to improve the detection position precision, coaxial being shaped with in the ring-type encircles 6 in the outer rim of positioning disk, be shaped with three outer annular recess 8 on the ring in the described ring-type, vertical mirror image is symmetrically installed with ring optoelectronic switch 7 in two on the circuit board that encircles in corresponding ring-type, thereby outer annular recess produced signal by described interior ring optoelectronic switch when described positioning disk rotated.
The ring height equates with its outer rim height in the ring-type of described positioning disk.
The height of described groove and outer annular recess equates; Width and the quantity of groove and outer annular recess are set according to actual conditions, and quantity is more, width is less, and the precision of its detection is also just higher, and the quantity of present embodiment further groove is five, and the quantity of outer annular recess is three.
Quantity and the position of described optoelectronic switch and interior ring optoelectronic switch are set according to actual conditions, the precision of more its detections of quantity is also just higher, adopts the optoelectronic switch of two horizon glass picture symmetries and the interior ring optoelectronic switch of two vertical mirror image symmetries in the present embodiment.
Working principle of the present utility model is:
When output shaft drives the positioning disk rotation, thereby the groove on its outer rim produces signal through optoelectronic switch, the groove of diverse location and the optoelectronic switch of diverse location produce different signals, in like manner, outer annular recess in the ring-type on the ring also produces signal when passing through interior ring optoelectronic switch, the interior ring optoelectronic switch of the outer annular recess of diverse location and diverse location produces different signals, and optoelectronic switch and interior ring optoelectronic switch send the signal that gathers to the control module (not shown) and carry out analysing and processing.
