Abstract

Przedmiotem zgłoszenia jest sposób zasilania parą wodną o parametrach ultra-nadkrytycznych tłokowych silników parowych i zawór wtryskowy do realizacji sposobu. Zasilanie parą wodną następuje za pomocą elektromagnetycznego zaworu wtryskowego o wysokiej częstotliwości pracy z iglicą (3) zakończoną stożkiem (12), której położenie - ruch w górę lub w dół powoduje zmianę przekroju pierścieniowej szczeliny pomiędzy gniazdem otworu wlotowego (15) głowicy(l4), a stożkiem (12) iglicy (3), przy czym iglic (3) sterowana jest elektromagnetycznie za pomocą solenoidu (10) poprzez sterownik (9) za pomocą komputera (8) w oparciu o dane z przetworników (7) o zmianach obciążenia silnika parowego w powiązaniu z prędkością obrotową wału korbowego tłokowego silnika parowego z częstotliwością 25 Hz lub wyższą, regulując dawki wody (pary) zależnie od stopnia obciążenia w czasie rzeczywistym.The subject of the application is a method of supplying steam with ultra-supercritical parameters to piston steam engines and an injection valve for the implementation of the method. Steam is supplied by a high-frequency electromagnetic injection valve with a needle (3) ended with a cone (12), the position of which - moving up or down - changes the cross-section of the annular gap between the seat of the inlet opening (15) of the head (I4), and the cone (12) of the needle (3), the needles (3) being electromagnetically controlled by the solenoid (10) by the controller (9) by the computer (8) based on the data from the transducers (7) on the changes in the steam engine load in conjunction with the rotational speed of the piston crankshaft of a steam engine at a frequency of 25 Hz or more, regulating the water (steam) doses depending on the degree of load in real time.
