Abstract
The invention relates to a method and a device for a valve for pressure regulation of steam, said valve including a steam plug (2) with bores (4) in its skirt (3), said bores being successively exposed as the valve is opened for achieving the regulated passage of the steam through the valve (1), and a water injection arrangement (5) situated downstream the steam plug (2) for temperature control of the steam. The water injection arrangement (5) is provided with at least one atomizing nozzle (7) for use from small openings of the valve (1), said nozzle (7) being connected to at least one feed means (9) for feeding auxiliary steam from the high pressure side (13) of the valve (1) in order to vaporize the water, said means (9) having its inlet in the area of the sealing surface (8) of the steam plug, such that the inlet will be shut off when the valve is closed. According to the inventive method, auxiliary steam is taken from the high pressure side (13) of the valve, said steam vaporizing the water used for temperature control of the steam amount regulated by means of the valve.
