FIELD: automatic adjusting equipment. SUBSTANCE: device has electromagnetic valve with inlet and outlet branch pipes, sensor and controller of temperature, adder, relay element and univibrators. Barrier valve is controlled by main and auxiliary electromagnets, cores of which are spring-loaded relatively to valve body. Core of main electromagnet is connected to barrier body and has ring-shaped bore, position of which changes along core axis by means of screw to change level of pipeline overlapping. Core of auxiliary element has slanting cut on the end. Shape of said cut matches the ring-shaped bore. Auxiliary element is used for fixing main magnet core after its switching on, and, consequently, is used for fixing locking body. Time of electromagnets operation is limited by univibrators. Movement of locking valve to one side is performed by means of main electromagnet, and movement of locking valve to other side is performed by means of spring action. EFFECT: increased device precision and capabilities. 3 dwg |
