FIELD: pipeline armature. ^ SUBSTANCE: valve comprises a case with a flow tube, inlet and outlet fittings, a moving control element in the form of a pipe with a seat, a sealing element, a solenoid drive and an armature moving back and forth positioned on the same axis, and a return string. The armature is connected to the control element via a gear unit, with the possibility to move the control element to the sealing element and back. The gear unit is formed by teeth of the rack, connected with the armature, gear wheel or its part, and by teeth on the surface of the control element. The solenoid drive and the return string, apart from the control element, are also separated from the flow tube by a disconnecting element. The device can be used to control the flow of fluids or gases in the pipes. ^ EFFECT: increased reliability of the solenoid valve while controlling the flow with considerable amount of foreign inclusions (magnetic inclusions among them); increased repair capability. ^ 1 dwg |
