Abstract

FIELD: thermal engineering; turbines using steam from geothermal sources. SUBSTANCE: turbine starting system has high-speed shut-off valve with actuator, starting valve connected for steam path in parallel to it, turning diaphragm, blocking control valve, valve-type switch, regulating pump, speed governing unit with servomotor and hydraulic cylinder. Blocking valve is connected through throttle to delivery line of regulation pump, through blocking line, to hydraulic cylinder, through line to actuator, and also to safety line. Valve-type switch is connected to protective line and also to starting line and to high-speed shut-off valve actuator. EFFECT: reduced metal input, improved reliability due to using protective devices provided with rotating rod and short-time operation of devices with rotating rod during starting period.

Изобретение относится к области теплоэнергетики, в частности может быть использовано в турбинах, работающих на паре от геотермальных источников. Цель изобретения - снижение металлоемкости, повышение надежности за счет использования защитных устройств, снабженных вращающимся штоком и с непродолжительной работой на пуске устройств с поступательно вращающимся штоком. Пусковая система турбины содержит быстрозапорный клапан с приводом, подключенный по пару параллельно ему пусковой клапан, поворотную диафрагму, блокирующий золотник, золотниковый выключатель, насос-регулятор, блок регулирования частоты вращения с сервомотором и гидроцилиндром. Блокирующий золотник подключен через дроссель к линии нагнетания насоса-регулятора, блокирующей линией - к гидроцилиндру, линией - к приводу, а также к линии защиты. Золотниковый выключатель подключен к линии защиты, к пусковому клапану и к приводу быстрозапорного клапана.The invention relates to the field of power engineering, in particular, it can be used in turbines running on steam from geothermal sources. The purpose of the invention is the reduction of metal consumption, increasing reliability through the use of protective devices equipped with a rotating rod and with short work on starting devices with a progressively rotating rod. The turbine starting system comprises a quick-closing valve with an actuator, a starting valve coupled in parallel with it, a rotary diaphragm, a spool blocking, a spool switch, a pump regulator, a speed control unit with a servomotor and a hydraulic cylinder. The blocking spool is connected through the throttle to the discharge line of the pump-regulator, the blocking line to the hydraulic cylinder, the line to the drive, as well as to the protection line. The slide switch is connected to the protection line, to the start valve and to the quick-valve valve actuator.
