SOLENOID-CONTROLLED SELF-LOCKING COCK Russian patent published in 2003 - IPC

FIELD: piping facilities. SUBSTANCE: invention relates to cocks with self-locking valves activated by solenoid. Proposed cock has hollow housing with main section provided with hole for actuating mechanism unit and discharge end piece projecting from main section and provided with hole on remote end of discharge end piece, water conduit system unit including solenoid valve, intake pipe connected to solenoid valve and passing through hole in base of housing, and discharge end piece pipe whose first end is connected to solenoid valve and second end adjoins the hole on remote end of discharge end piece, actuating mechanism unit connected to housing at hole for actuating mechanism unit and switch which is operated by actuating mechanism unit set into action by user. Actuating mechanism unit includes timer circuit connected to provide current for solenoid valve. Switch is connected to provide starting of timer circuit. Solenoid valve has body made of magnetic material, pole discharge end piece, reel made of nonmagnetic material, solenoid coil wound on reel, permanent magnetic placed inside reel drilled hole, flux concentrator made of magnetically permeable material, plunger made of magnetic material, spring, end face cover made of magnetic material, holder made of hard nonmagnetic material, and diaphragm. Detailed description of invention is given in dependent claims. Invention makes it possible to create electrically-controlled self-locking cock which can be energized by storage battery and operated by solenoid valve with automatic gate. EFFECT: facilitated assembling and replacement of components. 10 cl, 3 dwg
