DISTRIBUTING DEVICE FOR POWER COMPLEX WITH INDEPENDENT STEAM CONSUMERS Russian patent published in 1995 - IPC

FIELD: power mechanical engineering. SUBSTANCE: steam distributing unit has steam housing with supplying and discharging branch pipes, control valves with rods and seats, and hydraulic drives the number of which is equal to the number of the control valves. Each of the control valves has servomotor cutting slide valve and controller off. The servomotors are coupled with rods through ties and levers and also coupled with pressure and drain chambers and pulse passages. The steam housing and unit of the hydraulic drives are mounted in block on the common frame. The frame has top and bottom plates. Bushing with the bore, wherein intermediate bushing and slide valve for commutation of oil flows from the main and reserve oil pumps are receive, system for oil supply, and baffles are welded between the side walls. The baffles define chambers and spaces inside the frame. The space and chambers are in communication with pressure pipe lines of the pressure and reserve oil pumps. The spaces of the frame are in communication with the chambers through the slide valve and openings made in the plate. The steam housing is mounted on the frame through longitudinal and lateral keys. The dead center of the housing is the X-axis of the central branch pipe. The chamber is connected with a source of cooling water through passages made in the plate and shields the slide valve and shock-absorber against heat flux from the steam housing and its discharging branch pipes. EFFECT: enhanced reliability. 3 cl, 3 dwg
