Njengoba inkathi yokushisisa yaminyaka yonke isondela, i-NSEN izongena esigabeni esimatasa ehlobo.Ukulungiselela isizini yokushisisa yalo nyaka, amakhasimende ethu afake ama-oda amaningana ngokulandelana.Kulindeleke ukuthi u-800pcs wamavalvu ovemvane ashise azokhiqizwa kulo nyaka.Ngakho-ke, inkampani yethu inamasheya amaningi ohlobo lwe-butt welding, kanye ne-flange butterfly valve casting.

Ngezansi sizokwethula kafushane ama-valve emvemvane asetshenziselwa ukushisa kwesifunda;

Sonke siyazi ukuthi indawo yokushisa ithatha ikakhulukazi isitimu esishisa kakhulu namanzi ashisayo, ngakho-ke i-valve uvemvane evala uphawu kufanele ikhishwe lapho kukhethwa inketho, futhiivalve uvemvane evalwe ngensimbikufanele kukhethwe.Ngokusho kokubekwa uphawu, sihlukaniswe ngokuyinhloko sibe izinhlobo ezimbili, uhlobo lokuqala ivalve uvemvane evala uphawu, kanti uhlobo lwesibili luyinsimbi eqinile ebeka uphawu uvemvane.Lezi zinhlobo ezimbili zezakhiwo zokuvala zidinga ukunqunywa ngokuvumelana nezinga lokushisa kanye nezinga lokugeleza kwendawo yokusebenza.

Ngokwendlela yokuxhuma, izidingo eziyinhloko ziyiukushisela izinqefuthiuhlobo lwe-flange.Okwamanje i-NSEN ingahlinzeka ngezindinganiso zokuxhuma:

GOST 33259-2015, GOST 12815, EN1092-1, ASME B 16.5/B16.47

Uma ufuna ukwazi okwengeziwe ngesakhiwo salolu hlobo lwevalvu, sicela uchofoze isixhumanisi esingezansi
