초록 ▼

A handle for a magnetically actuated valve which bears rotating and fixed indicia for reading the valve position. The rotating indicia is placed upon a jacket carrying drive magnets. The fixed indicia is placed upon a cap covering the exposed end of a nonmagnetic bonnet separating the drive and driven magnet assemblies. External stop means prevent rotation of the jacket relative to the cap and bonnet more than about 90°. Internal stop means prevent the rotation of valve and driven magnets more than about 90°.

1. In a magnetically actuated valve comprising a cylindrical nonmagnetic bonnet separating drive and driven magnets, a handle for said valve comprising an annular jacket for holding the drive magnets, said annular jacket having an axial opening extending completely through the jacket such that the jacket may be telescoped over the nonmagnetic bonnet exposing an axial end of the bonnet, a cap for placing over said axial end of the nonmagnetic bonnet bearing indicia of opened and closed positions of the valve, an axial end of the jacket bearing indicia indicating a valve direction for alignment with the indicia on the cap to bring the valve into opened and closed positions and stops extending from said cap and said jacket for preventing more than about 90° rotation of said jacket relative to said cap and bonnet. 2. The handle according to claim 1 wherein said jacket comprises two snap together halves. 3. The handle according to claim 2 comprising two axially abutting annular chambers one for receiving the drive magnet and the other for receiving the stops extending from the caps are defined by radially extending annular walls. 4. The handle according to claim 2 wherein the snap together halves are injected molded plastic of different colors or other various visual indicators. 5. The handle according to claim 3 wherein the handle has an axially extending skirt on the end of the jacket away from the indicia, said skirt having means for slidably engaging an annular groove fixed relative to the valve. 6. In a magnetically actuated valve comprising a nonmagnetic cylindrical bonnet, a driven magnet assembly within the bonnet and a driving magnet assembly without the bonnet the improvement comprising means for positioning the driving magnets including a cylindrical cap for sliding over an axial end of the cylindrical bonnet, said cap having means for keying the cap to the cylindrical bonnet to prevent relative rotation thereof, indicia on the axial end of the cap indicating the open position of the valve, two radial stop tabs extending from said cap each tab having two radial stop surfaces, a housing for said drive magnets comprising a cylinder having a diameter greater than the outer diameter of the drive magnets, the housing having an annular end face and two annular partitions, the two annular partitions and the cylindrical housing defining a first space for receiving the cylindrical drive magnets, a rib extending radially into said first space for keying the magnets in a preselected position, one of said radial partitions and the annular end face defining a second space for receiving the tabs extending from the caps, ribs extending radially into said second space for engaging the stop surfaces of the tabs extending from said cap whereby the stop surfaces of the stop tabs are shaped and positioned with the stop ribs to restrict the annular rotation of the jacket relative to the cap and indicia on said end face indicative of position whereby comparison of the indicia on the cap and the end face provide for easy reading of the valve position.
