Abstract
Изобретение относитс к теплоэнергетике и может быть использовано при регулировании турбоустановок в составе энергоблоков. В верхний регенеративный подогреватель 6 питательной воды подвод т пар из отбора турбины 5 по линии 7 с обратным клапаном 8 и задвижкой 9 и из котла 1 по линии 11 с регулирующим клапаном 10 давлени пара, предохранительным клапаном 12 и защитным клапаном 15 с поршневым приводом и симпульсивным грузовым клапаном 16 и соленоидом 17 принудительного открыти импульсного клапана 16 при аварийных отключени х подогревател и энергоблока. Защитный клапан 15 имеет поршень, шток, шибер с разгрузочным отверстием и корпус. В режиме подачи пара в подогреватель из зоны фазового перехода котла 1 максимальное давление пара в подогревателе ограничиваетс защитным клапаном 15 с поршневым приводом, надпоршнева камера которого сообщаетс с линией 11 за регулирующим клапаном 10 через импульсный грузовой клапан 16, открывающийс при давлении пара в подогревателе 6 выше номинального и ниже давлени начала срабатывани предохранительного клапана . 2 з.п. ф-лы, 2 ил.The invention relates to a power system and can be used in the regulation of turbine installations in power units. The upper regenerative feedwater heater 6 is supplied with steam from a turbine 5 intake through line 7 with a check valve 8 and a valve 9 and from boiler 1 through line 11 with a steam pressure regulating valve 10, a safety valve 12 and a piston driven safety valve 15 the cargo valve 16 and the solenoid 17 forcibly opening the pulse valve 16 during emergency shutdowns of the preheater and power unit. The protective valve 15 has a piston, a rod, a gate with a discharge opening and a housing. In the mode of steam supply to the heater from the phase transition zone of the boiler 1, the maximum vapor pressure in the heater is limited by a piston-driven safety valve 15, the over piston chamber of which communicates with line 11 behind the control valve 10 through a pulsed cargo valve 16 opening at steam pressure in the heater 6 above nominal and below the start pressure of the safety valve. 2 hp f-ly, 2 ill.
