Types of valves and uses in Boiler in hindi

Hello friends Thermal power plant ke boiler me Valve ka ek important role hota hai eske bina power plant me power generation to kya Boiler running hi nhi hogi esliye ye ek very very important part hai Power plant ke boiler ka yahan hum apko thermal power plant ke Boiler me valves ka uses aur kahan use hota hai ye btayenge.

Thermal power plant ke boiler me valves kai types ke use kiye jate hain lekin jyada tar globe valve aur Gate valve aur Non-returning Valve (NRV) use kia jata hai esme v kai class ate hain to chliye hum en valve ke details aur Boiler me kahan use hote hain ye jante hain.

Types of valves and uses in Boiler in hindi

sath hi hum niche apko Gate aur globe valve pahchanne ka tarika bhi btayenge sabse pahle hum types of valve and uses in hindi dekhte hain.

Types of valve in boiler

Waise to kai types ke valve boiler me use kiye jate hain lekin hum apko boiler me sbse jyada use hone wale valve ke bare me btayenge-

1.) Gate valve 

Gate valve Ek type ka valve hai jisme spindle Direct fluid ya steam ko straight rok deta hai eska spindle rod gate jaisa work krta hai,
Esme apko Pressure same milta hai chahe Inlet se outlet ho,

Inme gate valve ke kai class hote hain jo steam temperature aur Pressure ke sahan capability ke hisab se hota hai.

Material quality aur capability ko categories kia gya hai jise class ke adhar per rkkha gya hai
Whrb boiler me Gate valve bohot jyada use kia jata hai eska Class temperature aur Pressure per depend krta hai,

West heat recovery boiler (whrb) me 1500# aur 2500# class ke use hote hai aur 800# class ke bhi mil jate hain.

Gate valve 2500# class uses in boiler

2500# class ka gate valve High temperature aur Pressure ko sahan kr leta hai esliye esko chahe whrb ya Afbc ya cfbc sabhi me esko main steam line ya steam line ya super heater me use krte hain.

Gate valve 2500 class

Ye 2500# class gate valve maximum temperature zone me use krte hain,
Ye valve apko Alloy Steel Material me mil jata hai.

1500# class Gate valve uses in boiler

Gate valve ka 1500# class wala valve boiler drum, Evaporator drain line, Economiser drain line me aur hood panel ke drain me use krte hain.

Gate valve 1500 class

Es class ke valve ko jahan medium temperature zone ho wahan use krte hain,

Es class ka gate valve apko carbon steel, stainless steel material ka mil jata hai.

800# Class Gate Valve in uses

Es class ka valve Boiler me use kia jata hai lekin kam ese shoot blower line, sample, es valve ko turbine k drain line me bhi use kia jata hai jahan medium temperature zone ho,

ye valve apko corbon steel material me mil jata hai.

2.) Globe Valve

Ye globe valve fluid flow control to krta hi hai esme fluid direct ya straight flow nhi hota jab fluid valve me inlet krta hai to wo zigzag hoker outlet ho jata hai esse fluid ka Pressure reduce ho jata hai.

Es type ke valve ( globe valve ) me inlet fluid aur outlet fluid me Pressure difference hota hai.

Esme bhi apko valve ke class jo material ke temperature aur Pressure ke sahan capability ke adhar per bnaya gya hai jo jyada tar use #2500 #1500 #800 class ke valve hote hain.

2500# class Globe Valve uses in Boiler

Globe valve ka ye 2500# class high temperature zone me use kia jata hai ye Drum ke upper Auxiliary vlave k rup me jahan alkali ( slow firing ) ke liye Tri sodium phosphate (tsp) chemical with water ko es valve se dala jata hai esme 2 inch size ka 2500# class Globe valve use krte hain.

Globe valve 2500 class

Sath hi main steam line me bhi es class aur type ke valve ko auxiliary valve k rup me use krte hain.

1500# class Globe Valve uses in Boiler

Globe valve ka 1500# class ko Boiler me medium temperature zome me use kia jata hai ese Boiler ke De-super heater ke spray line , HP Dosing spray line me, use kia jata hai.

Globe valve 1500 class

Ye valve apko Stainless steel aur Corban steel k material ke sath ata hai 

800# class Globe Valve uses in Boiler

Ye valve bhi apko boiler me mil jate hain lekin bohot kam sample cooler me ye valve use krte hain.

Globe valve 800 class

Non-returning Valve (NRV)

Nrv Power plant ke Boiler aur turbine me use kiya jata hai ye name se hi pta chalta hai ki kam kya krta hai jab water ya fluid ko return hone nhi deta, es valve me ek side se water inlet to krta hai lekin wapas usi water ko flow back hone nhi deta.

NRV Stainless steel aur carbon steel ka mil jata hai.

Non returning valve NRV

De-superheater me NRV Corban steel ka use kra jata hai esme jab de-super heater ka temperature bdhne per wahan feed water ko spray krte hai lekin water usme inlet krta hai lekin DSH se steam ya water ko NRV back flow hone nhi deta.

NRV HP Dosing me Stainless steel ka use kra jata hai, ye nrv hp dosing line se drum me juda hota hai dosing me chemical water ko drum me spray krte hain jisse dosing ka chemical with water to drum me jata hai lekin drum ka water ya steam dosing me NRV back flow ya wapas jane nahi deta.

Gate valve aur Globe valve ko pahchanne ka tarika

1.) Gate aur globe valve waise to dikhne me same hi hota hai work bhi fluid flow ka hai jo inlet se oulet me pressure flow slow krne wala golbe valve hota hai aur gate valve pressure same deta hai chahe inlet ho ya outlet.

2.) Globe valve me wheel move krta hai jab bhi Valve open krein aur , Gate Valve me wheel ka thread aage pichhe hota hai.

3.) Globe Valve me apko hexagonal nut mil jata hai wheel k upper aur gate valve me apko ellipsoid shape me mil jata hai ap photo me dekh skte hain.

Valve Class Pahchanne ka tarika

2500# Class ke valves me wheel plain hota hai chahe wo gate ho ya Globe, 1500# class ke valves ke Wheel me apko Doted dekhne ko milta hai.

Ball valve and butterfly valve uses

Power plant me Ball valve, Air line me aur water line Auxiliary cooling water pump line (Acwp) me use krte hain.

Ball valve

Butterfly valve jyadatar De- Minralize power plant me use kiya jata hai.

Conclusion

Power plant ke Boiler me Gate aur globe valve aur NRV hi maximum jagah me use kia jata hai aur eske her class aur categories hote hain jo humne apko es post me explaination krke btaya hai aur uske use kis jgh me hote hain ye bhi btaya hai sath hi pahchanne ka tarika bhi mentioned hai.

Ap above Article me photo dekhkr pahchan jayenge ki koun sa valve kis type aur kis category ka hai esse apko valve pahchanne aur use krne me help milegi aur koun sa valve kaisa work krta hai wo bhi achhe se pta chal jayega.

Ummid hai humara ye post apko jarur hi pasand ayega.

Thank you!
