Abstract
The utility model provides a water-spraying type steam temp. reducer, relating to a steam engine plant. The water-spraying type steam temp. reducer comprises a header wall, a water-spraying pipe, a protective sleeve barrel, a steam inlet and a steam outlet. The water-spraying type steam temp. reducer is characterized in that the outside of the water-spraying pipe is provided with 2-4 layers of protection pipes. The utility model adopts a multi-layer thin wall structure so that material thermal stress can be reduced and parts can be avoided from being damaged by thermal stress. Insufficient strength caused by insufficient wall thickness can be compensated. Simultaneously, once the parts appear cracks which are caused by long usage, the cracks can not throughout the whole wall because of the outside protection. So service life is extended and production safety factor is increased.
Description
A kind of water jet steam desuperheater relates to steam engine plant.
In the prior art; the header wall of the water jet steam desuperheat equipment in the heat power equipment, shower, protection sleeve etc. are all the thick wall single layer structure; because desuperheat equipment often is among the operating mode of suddenly cold and hot; equipment often bears temperature difference heat stress; when surpassing the yield strength of metal in this temperature; the thermal fatigue damage will take place, thus influence production, even serious accident takes place.
The purpose of this utility model provides and a kind ofly can solve equipment thermal fatigue damage problem, can improve the water jet steam desuperheater of device security performance again.
A kind of water jet steam desuperheater comprises header wall, shower, protection sleeve, steam inlet, steam ouput, it is characterized in that shower is with 2～4 layers of protective tube outward.
Because the utility model adopts the multi-layer thin wall construction; thereby can reduce the material temperature difference stress; avoid the thermal stress damage parts; remedy the insufficient strength that causes because of the wall thickness deficiency, simultaneously, in case parts use when year for a long time crackle taking place; there is outer layer protection can not once run through Quan Bi; prolong service life of equipment, can improve the production safety coefficient, had promotional value.
Fig. 1 is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is described in further details.
The utility model comprises header wall 1, shower 3, protection sleeve 5, steam inlet 7, steam ouput 8, is with 2～4 layers of protective tube 4 outside shower 3, and protective tube 4 adopts thin walled structures, generally can adopt 2 layers.During work, high-temperature steam enters through steam inlet 7, discharges from steam ouput 8 behind the desuperheat.In the shower 3 cold water is housed, the outside is full of high-temperature steam, and temperature difference stress is very big, and protective tube 4 can reduce temperature difference stress, prevents that shower 3 from working over a long time because of suddenly cold and hot produces fatigue crack, even fracture, causes cold water directly to spray on the header wall 1, causes the accident.Be with 2～4 layers of protective casing 6 outside protection sleeve 5, protective casing 6 adopts thin walled structures, can reduce the thermal stress at this position, prevents protective casing 6 fractures.Fixing protective layer 2 on header wall 1, protective layer 2 adopts sheetmetals to be fixed on the header wall 1 and with header wall 1 and leaves certain hole, to avoid header wall 1 because of suddenly cold and hot is damaged, prolongs the working life of equipment.The utility model is equally applicable to have the water jet steam desuperheater of individual layer flute formula water spray projector system.
