Technical field
The utility model is related to be mainly used in the industries such as power station, light room, petrochemical industry, especially a kind of steam temperature reducing and pressure reducing dress
Put.
Background technology
With the fast development of modern large-sized boiler, unit enter Large Copacity, high parameter, variation, increasingly automated
The new period of exhibition.The industrial circles such as Coal Chemical Industry, coal liquifaction need to utilize Large Copacity, Boiler Steam the subtracting through fast opening and closing of high parameter
Warm decompressor, meets the needs of process system.Conventional high-temperature high pressure reducing-and-cooling plant due to open and close slow, high noise,
Vibration is greatly and security reliability difference can not meet the requirement of its process system.
Utility model content
The purpose of this utility model is the defect for overcoming prior art, there is provided a kind of Desuperheating and decompressing device for steam, the dress
Put to possess and be related to rationally, performance is good, the characteristics of low production cost.
The technical solution adopted in the utility model is：
A kind of Desuperheating and decompressing device for steam, including mixed charge road, is connected with step-down in turn on the mixed charge road
System, cooling system and security system, it is characterised in that：The depressurizing system includes pressure-reducing valve and two pieces of restricting orifices, decompression
Valve is between two pieces of restricting orifices, and connects with mixed charge road；The cooling system includes throttling stop valve, check-valves
And adjustable nozzle, throttling stop valve and check-valves be sequentially connected, and be connected with adjustable nozzle bottom and adjustable nozzle bottom also with
Mixing branch pipe(tube) connection；The security system includes at least one spring safety valve and spring safety valve bottom and mixed charge road
Connection.
Further, pressure gauge and bimetallic thermometer are provided with the exit in the mixed charge road, to process after
Vapor (steam) temperature and pressure carry out real-time monitoring.
Further, the distance between the adjustable nozzle vertical direction center and neighbouring restricting orifice for 400 ~
1300mm, carries out spray cooling process in time to being depressured steam.
Further, the quantity of the spring safety valve is two, and two spring safety valve centre distances are 1600mm,
Being capable of smoothly pressure release when guaranteeing overvoltage.
Further, the mixed charge road port of export with the distance at the vertical center of neighbouring spring safety valve is
1000mm, it is ensured that being capable of smoothly pressure release when over-pressed.
The beneficial effects of the utility model are：
The utility model simple structure, using hydraulic pressure or pneumatic actuator, makes control reliable, quick, accurate, is manufactured into
This is low.Using desuperheat Split type structure after first reducing pressure, it is to avoid the alternate stress of material, security reliability is improved.Device has noise
Low（It is less than 80dBA）, shake little, tightness good, the features such as Parameter adjustable scope is big.The decompression process of steam is throttled using two pieces
Porous plate and pressure-reducing valve realize that coarse adjustment is reduced pressure, and are then then atomized spray by adjustable nozzle with through throttling stop valve and check-valves coarse adjustment
Enter the desuperheating water in mixed charge road, reach cooling purpose.
Description of the drawings
