FIELD: process engineering.
SUBSTANCE: processing of sealing surface at stop valve connection pipe end comprises the steps that follow. Valve top part and body built-in elements are remove from stop vale body to clear the body bore. Clamp counter-support is placed via body bore (14) into connection pipe or the other connection pipe and secured to its inner wall. Machining tool with support is fitted into the body and placed on said counter-support. Said tool process the sealing surface. This tool is withdrawn from counter-support and the body via its bore. Aforesaid clamp is detached from connection pipe and withdrawn via body bore. Valve top part and built-in elements are places at the body. Proposed device comprises clamp with counter-support, fastener (47) to interact with connection pipe inner wall, machining tool with support to be mounted at counter-support.
EFFECT: higher efficiency of processing.
