Description
Technical field
The utility model relates to a kind of electric valve positioning device, more particularly, relates to a kind of positioning device of electric valve actuator.
Figure viewed from behind technology
Existing miniature electric valve positioning device, the mode of the employing excess current that has location, shortcoming is the circuit complexity.The mode of the two sensitive switches of the employing that has location, shortcoming is that its structural adjustment is very not convenient, because what it adopted is a kind of fixed position mode, at most can only one adjustable, if therefore having caused the position of opening of valve harmonizes, off-position is just not necessarily accurate, if the off-position of valve is harmonized, it is just not necessarily accurate to open the position.In addition, above orientation type all can't obtain the feedback signal of valve position.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides that a kind of technology is simple, volume is small and exquisite, Location accuracy is high, reliable performance, applied widely and have a very electric valve positioning device of high performance-price ratio.
The utlity model has the dibit adjustable electric valve positioning device of valve position feedback function, comprise positioning disk, following positioning disk, inner disc and sensitive switch, it is characterized in that, described upper and lower two positioning disks are the stepped cylindrical body of hollow, the ladder top of following positioning disk is provided with positioning disk, the ladder side of following positioning disk is provided with two salient points, the arranged outside of following positioning disk has two sensitive switches, the ladder side of last positioning disk also is provided with two salient points, the outside of last positioning disk also is provided with two sensitive switches, and the inboard of following positioning disk is provided with inner disc.
Two salient points of described positioning disk are down spent, are distributed less than 180 degree scopes greater than 90 in the edge, side of following positioning disk ladder.
Described two salient points of going up positioning disk are also spent, are distributed less than 180 degree scopes greater than 90 in the edge in the side of last positioning disk ladder.
The two sensitive switches edge of the described arranged outside of positioning disk down is the outside 80-100 degree position distribution of positioning disk down.
Two sensitive switches of the described upward arranged outside of positioning disk are along the outside 80-100 degree position distribution of last positioning disk.
Described going up between positioning disk, following positioning disk and the inner disc can relatively rotate.
The beneficial effects of the utility model are, technology is simple, volume is small and exquisite, Location accuracy is high, reliable performance, have very high performance-price ratio, both can use in Large Electric valve positioning device, also can use in miniature electric valve positioning device.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The utility model comprises positioning disk, following positioning disk, inner disc and sensitive switch, and described upper and lower two positioning disks are the stepped cylindrical body of hollow.As shown in Figure 1, the ladder of last positioning disk 6 is provided with salient point 8 and salient point 12, two salient points are spent, are distributed less than 180 degree scopes greater than 90 in the edge, side of last positioning disk ladder, the arranged outside of last positioning disk 6 has two sensitive switches 3 and 4, two sensitive switches 3 and 4 outside 80-100 degree position distribution along last positioning disk.Fig. 2 is the structural representation of following positioning disk, it is identical with the ladder of following positioning disk 5 to go up positioning disk 6 as seen from Figure 2, the ladder of following positioning disk 5 is provided with salient point 7 and salient point 11, two salient points are also spent, are distributed less than 180 degree scopes greater than 90 in the edge, side of following positioning disk ladder, the outside of following positioning disk 6 also is provided with two sensitive switches 1 and 2, two sensitive switches 1 and 2 also along the outside 80-100 degree position distribution of last positioning disk.Fig. 4 is the mounting structure schematic representation of positioning device, last positioning disk 6 is sleeved on down above the ladder of positioning disk 5, inner disc 10 is installed in down in the cylindrical body of hollow of positioning disk 5, can relatively rotate between last positioning disk 6, following positioning disk 5 and the inner disc 10, to make things convenient for the debugging of optimum position in the installation process, the positioning disk that debugging finishes can be fixed as one three dishes by modes such as welding, riveted joint and bondings.In the outside of last positioning disk 6 and following positioning disk 5 the corresponding sensitive switch 3 that is provided with 4 with sensitive switch 1 with 2 also corresponding vertical, overlappingly 80-100 degree position, the outside along upper and lower two positioning disks is set.
When the electric valve proper functioning, the rotatingshaft 9 that is installed in inner disc 10 is rotated, also driving down simultaneously, positioning disk 5 rotates synchronously, when the salient point 7 on the positioning disk 5 rotates to sensitive switch 2 instantly, sensitive switch 2 actions, provide out the valve signal that puts in place, the sensitive switch 4 of positioning disk 6 correspondences promptly provides the feedback signal of valve position on this moment; When the salient point 8 on the last positioning disk 6 rotated to sensitive switch 8, sensitive switch 8 action provided and closes the signal that valve puts in place, this at present the sensitive switch 1 of positioning disk 5 correspondences promptly provide the feedback signal of valve position.Because only by control signal, electric current is minimum for sensitive switch, therefore greatly increased the working life of positioning device, guaranteed reliability of products.
