I-NORTECHis enye yeChina ehamba phambiliI-Globe Valve Umkhiqizi kanye Nomhlinzeki.

Yiziphi izinzuzo kanye nokungalungi kwe-ivalvu yomhlaba?
Izingxenye zokuvula nokuvala zevalvu yokuvala ziyizicucu ezibanzi ezimise okwepulaki, kanti indawo yokuvala iyisicaba noma iyindilinga, futhi ihamba ngokuqondile eceleni komugqa ophakathi woketshezi. Uhlobo lokunyakaza lwenduku lunohlobo lwenduku yokuphakamisa (isiqu sevalvu siyaphakanyiswa futhi sehliswe, isondo lesandla alikhuphuki), futhi kukhona uhlobo lwenduku yokuphakamisa ejikelezayo (isondo lesandla nesiqu sevalvu kuyajikeleza futhi kukhuphuke ndawonye, ​​​​futhi inathi ibekwe emzimbeni wevalvu). Ivalvu yokumisa ifaneleka kuphela uma ivuleke ngokuphelele futhi ivaliwe ngokuphelele, ukulungiswa kanye nokugoqa akuvunyelwe.
I-valve yokumisa iyi-valve yokuvalela ephoqelelwe, ngakho-ke uma i-valve ivaliwe, ingcindezi kumele ifakwe e-flap ukuze iphoqe ubuso bokuvala ukuthi bungavuzi. Lapho i-medium ingena ku-valve six kusuka ngaphansi kwe-valve disc, ukumelana okudingeka amandla okusebenza akunqobe amandla okungqubuzana kwesiqu se-valve kanye nokupakisha kanye nokucindezelwa okubangelwa yingcindezi ye-medium. Amandla okuvala i-valve makhulu kunamandla okuvula i-valve, ngakho-ke i-valve Ububanzi benduku kufanele bube bukhulu, ngaphandle kwalokho ipayipi lokujikijela isiqu se-valve lizohluleka. Eminyakeni yamuva nje, selokhu kwavela ama-valve azivala wona, indlela yokugeleza ephakathi ye-valve yokuvala ishintshile kusukela ngaphezulu kwe-valve clack iye emgodini we-valve. Ngalesi sikhathi, ngaphansi kwesenzo sengcindezi ephakathi, amandla okuvala i-valve mancane, kuyilapho amandla okuvula i-valve makhulu. Ububanzi bungancishiswa ngokufanele. Ngesikhathi esifanayo, ngaphansi kwesenzo se-medium, lolu hlobo lwe-valve nalo luqinile. I-valve yezwe lami "iSanhua" yake yathi indlela yokugeleza kwe-valve yokumisa kufanele ibe kusukela phezulu kuya phansi.
Uma ivalvu yokuvala ivuliwe, lapho ukuphakama kokuvula kwediski kungu-25%-30% wobubanzi obujwayelekile, ukugeleza kufinyelele esiphezulu, okubonisa ukuthi ivalvu ifinyelele endaweni evulekile ngokuphelele. Ngakho-ke, indawo evulekile ngokuphelele yevalvu yokuvala kufanele inqunywe ngokushaywa kwediski yevalvu.
Ivalvu yokumisa ingahlukaniswa kanje: ivalvu yokumisa, ivalvu yokumisa yesiqu sentambo ephezulu, ivalvu yokumisa yesiqu sentambo ephansi, ivalvu yokumisa eqondile, ivalvu yokumisa ekhoneni, ivalvu yokumisa enezindlela ezintathu, ivalvu yokumisa yamanje eqondile, ivalvu yokumisa i-plunger, ivalvu yeglobe enesimo senaliti.
Izinzuzo: isakhiwo esilula, ukukhiqiza kanye nokugcinwa okulula.
Umugqa osebenzayo mncane, kanti isikhathi sokuvula nokuvala sifushane.
Ukusebenza kahle kokuvala, ukungqubuzana okuncane phakathi kwezindawo zokuvala, kanye nokuphila isikhathi eside.
Okubi:
Ukumelana noketshezi kukhulu, futhi amandla adingekayo ekuvuleni nasekuvaleni makhulu.
Ayifaneleki imidiya enezinhlayiya, i-viscosity ephezulu futhi kulula ukuyicola.
Ukusebenza kabi kokulungisa
Izinyathelo Zokuqapha Zokufaka Nokulungisa: Ivalvu yokuma eqhutshwa yisondo lesandla kanye nesibambo ingafakwa kunoma iyiphi indawo yepayipi.
Amasondo esandla, izibambo kanye nezindlela eziguquguqukayo akuvunyelwe ukusetshenziswa ekuphakamiseni. Isiqondiso sokugeleza kwe-medium kufanele sihambisane nesiqondiso somcibisholo oboniswe emzimbeni wevalvu.
