Abstract
A positioning device of a contact type heating valve comprises a fixing disc, a rotating arm and a pointer; the fixing disc and the rotating arm are respectively provided with a fixing contacting point and a moving contacting point, and one end of the rotating arm is arranged in the center of the fixing disc, and the facade of the fixing disc is provided with scale and a pointer. The utility model has the advantages that: the rotating contacting point can be employed to determine the opening degree and exactly position an automatically measured IC card heating valve, thus determining the precision of the valve opening angle, enhancing the product reliability, and ensuring the precision of valve opening angle, which can make sure the accuracy of measuring water flux under constant pressure.
Description
Technical field
The utility model relates to a kind of positioning device of contact type heat supply valve, is used for that the position to valve positions when automatic or manual is regulated flow, to reach the purpose of accurate measurement.
Background technique
The flow control of existing heat supply valve is the position of determining the place by the rotation time of valve rod, can not accurately locate, and causes the heat metering precision not high, can not satisfy the purpose of accurate measurement.
Summary of the invention
The purpose of this utility model just provides a kind of positioning device of contact type heat supply valve, to solve the not high problem of heat metering precision that prior art exists.
The technical solution of the utility model is: comprise fixed tray, cursor and pointer, respectively be provided with corresponding fixed contact and movable contact on fixed tray and cursor, an end of cursor is installed in the center of fixed tray by rotation positioning device; Be provided with scale and pointer in the front of fixed tray.
Rotation positioning device comprises that retaining ring, rolling disc, spring and positioning bead constitute, retaining ring is loaded on the outer circumferential face of rolling disc, inner peripheral surface at retaining ring is provided with a plurality of location pit that is uniformly distributed along the circumference, outer circumferential face at rolling disc is provided with radial blind holes, in this blind hole, pack into spring and positioning bead, this positioning bead is limited in the interior also part of reducing of blind hole and stretches out outside this blind hole mouth, and this positioning bead coincide with described location pit is corresponding mutually.
The utility model has the advantages that: utilize the contact of rotating to determine that the aperture of valve can be the IC-card heating installation valve location of autoweighing accurately, thereby determine the accuracy of the angle of valve opening, improve the degree of reliability of product; Guarantee valve unlatching angle accurately, provide assurance to the accuracy of the flow of measuring the water under constant pressure.
