Imveliso Entsha Yokufika—IVALVU YESANGO LE-DIN PN16 KNIFE

Kwimizi-mveliso apho ukuphatha ulwelo oluqinileyo, i-slurry, okanye izinto ezinkulu kuyingxaki yemihla ngemihla, ukuthembeka nokusebenza kakuhle kweenkqubo zokulawula ulwelo kubaluleke kakhulu.Ivalvu yeSango leMese—isisombululo esikhethekileyo esenzelwe ukujongana nezinye zezona zicelo zinzima kumashishini afana nemigodi, unyango lwamanzi amdaka, i-pulp kunye nephepha, kunye nokulungiswa kweekhemikhali.

Kutheni Ukhetha Iivalvu Zesango Le-I-FLOW?

1. Yenzelwe iimeko ezinzima

I-Qingdao I-Flow'siivalvu zesango lemelaZenzelwe ukusika imidiya erhabaxa nexineneyo ngokulula. Isango elibukhali linqumla ulwelo kunye nezinto eziqinileyo ngokufanayo, nto leyo eyenza ukuba libe lolona khetho lufanelekileyo kwimisebenzi ejongene nezinto ezinzima. Ulwakhiwo oluqinileyo luqinisekisa ukuba ezi valve ziyakwazi ukumelana neemeko zoshishino ezinzima, zibonelela ngokusebenza okuzinzileyo nokuthembekileyo.

2. Uyilo olupheleleyo lweBore ukuze luhambe kakuhle

Zethuiivalvu zesango lemelaiqulethe uyilo olupheleleyo lwembobo, oluvumela ukuhamba kolwelo ngaphandle kwemida nokuba lungakanani na ubukhali balo. Ngokungafaniyo nezinye iivalvu, akukho mingxunya ingaphantsi kwesango apho i-medium inokuqokelelana khona, okuqinisekisa ukuhamba okuthe tye nokusebenzayo kunye nokunciphisa umngcipheko wokuvaleka. Olu phuculo loyilo luguqulela ekusebenzeni ngcono kwevalvu iyonke kunye nokuthembeka.

3. Ukuzicoca kunye nokugcinwa kancinci

Enye yezona zinto zibalaseleyo kwi-iivalvu zesango lemelayindlela ezikwazi ukuzicoca ngayo. Njengoko ivalvu ivuleka, amasuntswana ayatyhalwa kwisango, nto leyo enciphisa umngcipheko wokuvaleka. Kwizinto ezirhabaxa okanye ezigcwele amasuntswana, ii-gate scrapers ezikhethwayo kunye nee-deflector cones zibonelela ngokhuseleko olongezelelweyo kwi-packing gland. I-packing gland ephezulu nayo inokutshintshwa, nto leyo evumela ukuba kube lula ukutshintshwa ngaphandle kokuyichitha ivalvu—okunciphisa ixesha kunye neendleko zokulungisa.

4. Ufakelo Oluguquguqukayo Noluguquguqukayo

I-Qingdao I-Flow'siivalvu zesango lemelaZenzelwe ukuba zikwazi ukuhambahamba ngendlela ehambelana necala ngalinye, nto leyo evumela ukuba zifakelwe ngendlela eguquguqukayo ngaphandle kwemiqathango yecala lokuhambahamba. Oku kuguquguquka kwenza ukuba zifaneleke kwiintlobo ngeentlobo zezicelo zoshishino. Ukulula koyilo lweevalvu kuqinisekisa ukuba ukufakwa nokugcinwa kulula kwaye kuyabiza.

5. Ukuthobela iMigangatho yoShishino

Zethuiivalvu zesango lemelaZenziwe ngokwemigangatho ephezulu yoshishino, kuquka iBS5150. Zifumaneka kuzo zombini iintlobo ze-OS&Y (Outside Screw and Yoke) kunye ne-NRS (Non-Rising Stem), ezi valve zibonelela ngokuguquguquka kwindlela yoyilo kunye nokusetyenziswa. Ziza ngobukhulu obuqala kwi-DN50 ukuya kwi-DN300 (2″ ukuya kwi-12″) kwaye zifumaneka kwizixhobo ezifana neCast Iron (CI) kunye neDuctile Iron (DI), kunye nomlinganiselo woxinzelelo we-PN10. Oku kuzenza zifaneleke kwiindawo ezininzi zoshishino ezifuna kakhulu.

6. Ukuqina kunye nobomi benkonzo ende

Ukusetyenziswa kwezixhobo ezikumgangatho ophezulu kwishishini lethuiivalvu zesango lemelaiqinisekisa ukuqina kwexesha elide kunye nokumelana nokuguguleka. Iivalvu zenzelwe ukuhlala ixesha elide, kunye neempawu ezifana nokutywinwa okukhuselekileyo kunye ne-full plain bore ezinegalelo kubomi bazo benkonzo ende. Oku kunciphisa ukuphindaphindwa kokutshintshwa kunye neendleko ezinxulumene noko, okubonelela ngexabiso elihle ngokuhamba kwexesha.

7. Uluhlu olubanzi lwezicelo

Iivalvu zesango lemelaZibaluleke kakhulu kumashishini aqala kulawulo lwamanzi amdaka ukuya kwimveliso yepulp kunye nephepha. Ukukwazi kwazo ukusingatha zombini izicelo zokuvula/ukuvala kunye nokuqhobosha kuzenza zibe lukhetho oluguquguqukayo kwiinkqubo ezahlukeneyo zoshishino. Iivalvu zesango lemela zeQingdao I-Flow zenzelwe ukubonelela ngokusebenza okuthembekileyo nokungaguquguqukiyo kumacandelo ahlukeneyo, ezilungelelanisa neemfuno ezithile zesicelo ngasinye.
