Sir bhut saare valves and parts hote hn.. unme pilot line ko hum kis tarah samjhe. Pilot operated valves and pilot line me confusion hoti h.. or pilot line ka Matlb kya hota hai.. sir ispe ek video bnaiye
Pilot line jo hai system se liye hue hue kam pressure wala line hai.. Agar variable displacement piston pump jiska pressure 300-350 bar haii usko operate karna hotha tho waha usko system se hi liye kam pressure wala line jiska pressure 40-50 bar ko use karthe hai.. Dekne me bi pilot line pathla diktha hai aur aur main line mota diktha hai.. Ye pilot line ki baath hai.. Aur pilot operated valve ka mathlab hotha hai.. Example pilot operated relief valve ko hi lelijiye.. Direct acting valve me main line pressure se open hojayega jiska pressure range zyada rahtha hai (agar maximum pressure 1000 bar hotha thoh setting ka hisab se 500 se open karna shuru hotha hai) . Ab pilot operated pressure relief valve ko lelo jiska pressure range kam hoga ye baath zaroor yaad rakna ki pilot operated relief valve me pilot line internal part hai.. Pilot operated relief valve me oil relief valve ka oil se hi aatha hai vo chota line pressure relief valve ke dusre taraf daba ke close raktha hai.. Jab pressure reach hua vo pilot line pressure relief valve ko open karne detha hai.. Samja nahi toh English me bi miltha hai Google me thoda mehnath kar sab samaj aayega..ayr baad me muje thanks boliyega 😊❤
