FIELD: water supply, particularly sanitary repair-and-operational means thereof. ^ SUBSTANCE: leakage elimination method involves removing valve from threaded seat made in tap body; replacing sealing packing; securing guiding pipe in above seat of tap body; installing metal-cutting tool inside the guiding pipe, wherein metal-cutting tool is spindle having cylindrical part, metal-cutting head to remove defective metal layer from annular shoulder end, end part, along with movable limiter, which prevents axial movement of spindle and shank providing connection with drive means; removing defective metal layers so that newly formed end surface of annular shoulder brought into contact with sealing packing of shutoff valve is oriented transversely to inner cylindrical surface of guiding pipe; separating the guiding pipe from above tap body seat; connecting the valve to the tap; pressing sealing packing to end of annular shoulder enclosing water inlet orifice. Device for leakage elimination comprises tap body with threaded seat for valve connection and with annular shoulder enclosing water inlet orifice. Tap body also has water outlet channel. Threaded tap body seat is coaxial to annular shoulder. Guiding pipe is temporary secured to tap body seat having flat outer end surface transversal to inner cylindrical surface thereof. Spindle is arranged inside the guiding pipe and may perform predetermined axial movement and reversible rotation. Cylindrical surfaces of spindle and guiding pipe brought into contact are coaxial to threaded seat and annular shoulder. Metal-cutting head diameter exceeds outer diameter of annular shoulder. End surface of metal-cutting surface extends transversely to cylindrical spindle part. ^ EFFECT: increased quality of acting water tap usage and repair, elimination of water leakage and increased service life of the tap. ^ 9 cl, 10 dwg |
