Abstract
The utility model discloses a valve position counter used for a multi-rotation electric actuator. The valve position counter comprises a transmission gear group composed of four gears and capable of achieving 4096 turns. A black and white coding chart with gray code is coded on each gear which corresponds to a group of infrared light-emitting tubes and a group of light-sensing elements corresponding to the infrared light-emitting tubes, and each group of light-sensing elements are connected with a processing circuit used for processing light-sensing element signals and recording gear position. By means of the technical scheme, the valve position counter is capable of recording valve position and accurate in counting, valve position data cannot be lost, and standby batteries are not required. The valve position counter protects valves, and the problem of valve damage caused by loss of valve position data is resolved.
Description
Technical field
The utility model relates to a kind of valve position counter of electric actuator, relates in particular to a kind of valve position counter for many revolution electric actuator.
Background technique
The valve position counting of many revolution electric actuator all is to adopt the magnetoelectricity increment type in the market, non-memory formula, this just needs final controlling element rotating moment, and circuit must be worked, and needs reserve battery.When battery did not have electricity, the valve position data were very easily lost, and caused the valve position miscount, caused the control of electric actuator to be broken down, and valve damages.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, provide a kind of can the recording valve position, counting accurately, the valve position data can not be lost and do not need the valve position counters that are used for many revolution electric actuator of reserve battery.
Technological scheme: in order to realize the foregoing invention purpose, the technological scheme that the utility model adopts is:
A kind of valve position counter for many revolution electric actuator, comprise by four gears and form the driving gear set that can realize 4096 circles, the black and white code pattern that is composed of Gray code on each gear, the corresponding one group of infraluminescence pipe of each gear and one group of photoreceptor element corresponding with the infraluminescence pipe, described each group photoreceptor element and being connected with the processing circuit that is connected gear position for the treatment of the photoreceptor element signal.
Guan Weisi of each group infraluminescence, the photoreceptor element of each group is four.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
Valve position counter for many revolution electric actuator of the present utility model is made of the driving gear set that can realize 4096 circles four gears, the black and white code pattern that is composed of Gray code on each gear, when black to the coding mask of the illumination of infrared luminotron tube, infrared light is by black absorption, infrared light reflection when shining on the white, when photoreceptor element receives the infrared light of launching, export a level signal; The corresponding one group of infraluminescence pipe of each gear (four); one group of photoreceptor element (four), the signal of all photoreceptor element outputs is all recorded the cogged position of institute through after the signal processing; and this position signal is unique; the record valve position is accurate, does not need reserve battery, and can not lose the valve position data; guaranteed the accurate control of electric actuator; do not need reserve battery, protected valve, can not damage because of the valve that the valve position loss of data causes.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
As depicted in figs. 1 and 2, a kind of valve position counter for many revolution electric actuator, comprise by four gears and form the driving gear set 1 that can realize 4096 circles, the black and white code pattern 2 that is composed of Gray code on each gear 11, the corresponding one group of infraluminescence pipe 3 of each gear and one group of photoreceptor element corresponding with the infraluminescence pipe 4, described every group of photoreceptor element be connected with the processing circuit that is connected gear position for the treatment of the photoreceptor element signal, Guan Weisi of each group infraluminescence, the photoreceptor element of each group is four.
The utility model is made of the driving gear set that can realize 4096 circles four gears, the black and white code pattern that is composed of Gray code on each gear, when black to the coding mask of the illumination of infrared luminotron tube, infrared light is by black absorption, infrared light reflection when shining on the white, when photoreceptor element receives the infrared light of launching, export a level signal; The corresponding one group of infraluminescence pipe of each gear (four), one group of photoreceptor element (four), the signal of all photoreceptor element outputs the cogged position of institute is all recorded, and this position signal is unique through after the signal processing.
Claims (2)
1. one kind is used for the valve position counters that turn round electric actuator more, it is characterized in that: comprise by four gears forming the driving gear set that can realize 4096 circles, the black and white code pattern that is composed of Gray code on each gear, the corresponding one group of infraluminescence pipe of each gear and one group of photoreceptor element corresponding with the infraluminescence pipe, described every group of photoreceptor element be connected with the processing circuit that is connected gear position for the treatment of the photoreceptor element signal.
