Abstract

ELECTROMAGNETIC VALVE containing opposed electromagnets with a common magnetic core, between spring-loaded corners of which an elastic conduit is placed for the passage of the working medium with the possibility of clamping the conduit cortex of electromagnets, characterized in that, in order to increase the reliability of operation, perpendicular to the main magnetic circuit is installed two additional electromagnets with fixed poles, and the elastic pipe is coated on the outside with a ferromagnetic material.

Description

This invention relates to a valve industry.

The purpose of the invention is to increase the reliability of the electromagnetic valve with an elastic closure body by eliminating permanent deformation of the latter.

FIG. 1 shows a solenoid valve, a slit; in fig. 2 is a diagram of the valve in the initial position; in fig. 3 - scheme of the included valve.

The solenoid valve contains a closed magnetic conductor 1, on which electromagnets 2 are mounted with bark 3, preloaded springs 4, and electromagnets 5 with fixed poles 6, between which is placed an elastic tube 7 with flanges 8, is covered outside with ferromagnetic material 9. The winding of electromagnets is connected to the unit management 10.

The valve operates as follows. In the open position of the valve box 3

electromagnets 2 are pressed by springs 4 to the walls of the magnetic circuit 1, and the outer surface of the elastic tube 7 under the influence of the magnetic forces of the electromagnets 5 is attracted to the poles 6, while the surface

the tube 7 assumes the semicircular shape of the end surfaces of the poles 6. When the valve from the control unit 10 is closed, the windings of the electromagnets 2 are supplied with direct current and the core 3, overcoming the forces of the springs 4, move towards each other

friend, pinching the elastic tube 7 and thereby shut off the valve.
