I-NORTECHis enye yeChina ehamba phambiliI-Globe Valve Umkhiqizi nomhlinzeki.

Yiziphi izinzuzo kanye nebubi be-i-valve yomhlaba?
Izingxenye zokuvula nezokuvala zevalvu yokuvala zingamacembe abanzi amise okwepulaki, kanti indawo yokuvala iyisicaba noma i-conical, futhi ihamba ngokulandelana emgqeni omaphakathi woketshezi.Indlela yokunyakaza yenduku inohlobo lwenduku yokuphakamisa (isiqu se-valve siyaphakanyiswa futhi siyehliswa, isondo lesandla alinyuki), futhi kukhona uhlobo lwenduku ezungezayo ephakamisayo (isondo lesandla nesiqu se-valve ziyazungeza futhi zikhuphuke ndawonye, ​​futhi i-nati ibekwe emzimbeni we-valve).I-valve yokumisa ifaneleka kuphela ukuvuleka ngokugcwele futhi ivalwe ngokugcwele, ukulungiswa kanye ne-throttling akuvunyelwe.
I-valve yokumisa iyi-valve yokuvala ephoqelelwe, ngakho-ke lapho i-valve ivaliwe, kufanele kufakwe ingcindezi ku-flap ukuze kuphoqe indawo yokuvala ukuthi ingavuzi.Lapho i-medium ingena ku-valve yesithupha isuka ngaphansi kwediski ye-valve, ukumelana namandla okusebenza okudingeka ukukunqobe amandla okungqubuzana kwesiqu se-valve kanye nokupakisha kanye nokucindezela okukhiqizwa ukucindezela kwendawo ephakathi.Amandla okuvala i-valve makhulu kunamandla okuvula i-valve, ngakho-ke i-valve Ububanzi benduku kufanele bube bukhulu, ngaphandle kwalokho ipayipi le-valve le-jacking le-valve lizohluleka.Eminyakeni yamuva nje, selokhu kwavela ama-valve azivalayo, indlela yokugeleza okuphakathi kwe-valve yokuvala ishintshile ukusuka ngenhla kwe-valve ingena emgodini we-valve.Ngalesi sikhathi, ngaphansi kwesenzo sokucindezela okuphakathi, amandla okuvala i-valve mancane, kuyilapho amandla okuvula i-valve makhulu.Ububanzi bungancishiswa ngokufanele.Ngesikhathi esifanayo, ngaphansi kwesenzo se-medium, lolu hlobo lwe-valve luphinde luqine.i-valve yezwe lami i-“Sanhua” yake yabeka ukuthi i-valve yokuma kufanele isuke phezulu iye phansi.
Lapho i-valve yokuvala ivuliwe, lapho ukuphakama kokuvula kwe-disc kungu-25% -30% we-diameter yegama, ukugeleza sekufinyelele phezulu, okubonisa ukuthi i-valve ifinyelele endaweni evulekile ngokugcwele.Ngakho-ke, indawo evulekile ngokugcwele ye-valve yokuvala kufanele inqunywe ngokushaywa kwediski ye-valve.
I-valve yokumisa ingahlukaniswa ngokuthi: i-valve yokumisa, i-valve yokumisa isiqu esiphezulu, i-valve yokumisa intambo ephansi, i-valve yokumisa eqondile, i-engeli yokumisa i-valve, i-valve yokumisa yezindlela ezintathu, i-valve yokumisa yamanje eqondile, i-plunger stop valve, inaliti eyakhiwe i-valve yomhlaba.
Izinzuzo: isakhiwo esilula, ukukhiqiza okulula nokugcinwa.
I-stroke yokusebenza incane, futhi isikhathi sokuvula nokuvala sifushane.
Ukusebenza kahle kokuvala, ukungqubuzana okuncane phakathi kwezindawo zokuvala, nempilo ende.
Ububi:
Ukumelana noketshezi kukhulu, futhi amandla adingekayo ukuvula nokuvala makhulu.
Ayifanele imidiya enezinhlayiya, i-viscosity ephezulu futhi kulula ukuyipheka.
Ukusebenza okungalungile kokulungisa
Izinyathelo zokuphepha zokufakwa nokulungiswa: Ivalvu yokumisa esebenza isondo lesandla nesibambo ingafakwa kunoma iyiphi indawo yepayipi.
Amasondo ezandla, izibambo kanye nezindlela eziguquguqukayo azivunyelwe ukuthi zisetshenziselwe ukuphakamisa.Isiqondiso sokugeleza se-medium kufanele sihambisane nesiqondiso somcibisholo oboniswe emzimbeni we-valve.
