ES78342U - Electromagnetic operating step valve (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Electromagnetic operating step valve, which is essentially constituted by an electrical and a mechanical part both contained within a suitable protective box, the first being determined by an electromagnet fixed to a frame and the second, by at least one valve vertical tubular also fixed to said frame and equipped at its upper end with an escape and safety opening and provided with a lateral conduit for the entry or exit of the fluid, while, at the low end, there is another circulation opening for that same fluid, appearing in the extremities of said valve two conical adjustment seats, and being able to slide in both directions through the interior of the repeated valve a moving shutter axially linked by its lower part, through a damper, preferably a spring, to the mobile armature of the electromagnet, whose obturator has two extreme conical heads side notches for passage of the fluid, heads cooperating with the aforementioned seats, resulting in the opening of the bottom naso of the valve and the simultaneous closure of the escape and safety upper, to allow the circulation of the fluid between said lateral duct and the lower one, when the electromagnet is excited and attracts the armature with the obturator, which forces it to ascend, producing the upper escape opening and the subsequent interception of the lower one when the aforementioned obturator descends due to its own weight when the current is interrupted electrical and stop the action of the electromagnet.
