Abstract
The utility model relates to an electric valve positioning device. The electric valve positioning device mainly comprises micro switches and a positioning disk and is characterized in that the positioning disk is fixedly connected onto a rotary shaft of a valve, a positioning notch is disposed on the positioning disk, a micro switch A and a micro switch B are respectively disposed at two positions tangent to the positioning disk, and the positioning disk is used as a circle center for the two micro switches distributed at angles ranging from 94 degrees to 104 degrees. The electric valve positioning device has the advantages of being capable of achieving more accurate rotation positioning of 90 degrees under a single notched positioning disk, especially achieving accurate positioning of a tee valve and greatly reducing valve adjustment techniques of the tee valve.
Description
Technical field
The utility model relates to a kind of electric valve positioning device.
Background technique
At present, employed mortor operated valve positioning device mostly adopts single breach positioning disk and is the sensitive switch composition that 90 degree distribute with it on the market; Positioning disk is installed on the output shaft of electric actuator, owing to exist the joint of motion spacious amount, valve rod and electric actuator to exist the locating notch of return difference, positioning disk and the contact of sensitive switch to have positioning error between valve ball and the valve rod, more than the accumulation of various errors cause positioning disk to turn 90 degrees, with the valve ball of valve only turned round about 80 degree.For straight-through valve,, just can not open valve fully if it is accurate to guarantee to close valve; For triple valve, want to guarantee the accurate of two positions, just more difficult the realization.
Summary of the invention
The utility model is intended to overcome the deficiency of existing electric valve positioning device technology, provides a kind of and can realize the rotating electric valve positioning device of valve ball 90 degree more accurately.
The electric valve positioning device, mainly constitute by sensitive switch, positioning disk, it is characterized in that: described positioning disk 1 is fixed on the valve rotatingshaft 2, positioning disk is provided with locating notch 5, with on two tangent positions of positioning disk sensitive switch A 3, sensitive switch B 4 are set respectively, described two sensitive switches are the center of circle with the positioning disk center, are the 94-104 degree and distribute.
The beneficial effects of the utility model are: can realize 90 degree revolution location more accurately under single breach positioning disk, particularly for the accurate location of triple valve, greatly reduce the accent valve technology of triple valve.
Description of drawings
Fig. 1 is the utility model structural representation, wherein: 1, positioning disk, 3, sensitive switch, 4, sensitive switch, 5 locating notches, 6, the contact.
Fig. 2 is a B-B sectional view among Fig. 1, wherein: 1, positioning disk, 2, the valve rotatingshaft.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2: the electric valve positioning device, mainly constitute by sensitive switch, positioning disk, it is characterized in that: described positioning disk 1 is fixed on the valve rotatingshaft 2, positioning disk is provided with locating notch 5, with on two tangent positions of positioning disk sensitive switch A 3, sensitive switch B 4 are set respectively, described two sensitive switches are the center of circle with the positioning disk center, are the 94-108 degree and distribute.The sensitive switch distribution angle decides according to the spacious amount, the error that exist everywhere; The contact 6 of sensitive switch is ejected into locating notch and represents valve position.
