Abstract

The invention relates to an overall regulation and water spraying atomization steam temperature reducing device. The device comprises a regulating valve and a nozzle, wherein a valve rod of the regulating valve is connected with a valve core; a regulating sleeve is arranged in the regulating valve; at least the regulating sleeve walls of two sections of the regulating sleeve are provided with small holes; the sections are distributed on the regulating sleeve at an equal interval; water can enter the regulating sleeve only through the small holes; the valve core slides in a cavity of the regulating sleeve to shield or open the small hole; the nozzle comprises a nozzle valve, a nozzle plug, a valve cavity, a spring cavity and a spring; a water spray nozzle of the valve cavity is an inverted cone-shaped nozzle plug seat; the front end of the nozzle plug is matched with the nozzle plug seat; the rear part of the nozzle plug passes through the valve cavity and the nozzle valve to enter the spring cavity; after the spring in the spring cavity is compressed by the rear part of the nozzle plug, the end part of the nozzle plug is positioned by pins and the end part of the spring cavity; the nozzle valve is provided with mounting thread and a water flow passage; the nozzle is connected with a temperature reducing water pipe through the mounting thread; and a water outlet of the regulating valve is connected with the temperature reducing water pipe through a flange.

Description

Technical field: [0001] The invention relates to a temperature and pressure reduction device for a steam pipeline, in particular to a steam temperature reduction device for overall regulation and water spraying and atomization. Background technique: [0002] For the secondary comprehensive utilization of superheated steam used for power generation in thermal power plants, based on the consideration of safety, it is often necessary to reduce the temperature and pressure before it can be provided to the user. At present, the temperature reduction system is generally composed of water supply distribution valves, fixed nozzles, throttling devices, etc. , Their desuperheating process is: spray cooling water to the superheated steam through the desuperheating water spray device (fixed nozzle), and the cooling water absorbs heat through the steam, thereby reducing the temperature of the superheated steam. The nozzle area of ​​this structure is not adjustable, and the water spray vo...
