OPERATION PROCEDURE AND DESIGN OF ELECTRO-MAGNET VALVE OF HIGH PRESSURE Russian patent published in 2010 - IPC F16K31/02 

FIELD: machine building.

SUBSTANCE: group of inventions refers to pipelines accessories engineering. The electro-magnet valve of high pressure consists of a case. The case has a central branch and a through channel for working agent. Internal surface of the case on one end corresponds to a ring out of not magnetic material splitting surface of a truncated cone in two halves. The latter conjugates with surface of an electromagnet anchor. The anchor is made in form of a truncated cone with through channels for working agent flow and with a cylinder guiding lug on its top. The guiding lug is installed in a bushing. The bushing is fabricated out of not magnetic material and it is spring-loaded from the end opposite relative to conic part of the anchor. The locking element of a cylinder type is arranged in the central part of the electromagnet anchor base. In the central part of the case cover there is made a saddle. An outlet branch for working agent is made on a back side of the cover. An electromagnet coil in a shroud is installed in the case. The shutoff element has a cylinder lug along perimetre of the end on the back relative to the saddle side. With this lug the shutoff element is maintained by means of a captive nut with a gap in lengthwise and cross directions at the end of the anchor. The nut has external thread. Plane of the cylinder lug end on the side of the saddle is at acute angle to orthogonal plane to lengthwise axis of the shutoff element. Also there is disclosed the procedure of electromagnet valve operation.

EFFECT: decreased power consumption and decreased dimensions of valve.
