Isishwankathelo

Iivalvu zebhola ezifakwe kwi-trunnion zenzelwe ukutywina umsinga ongasentla. Uyilo lwesihlalo lunendlela yokukhulula umngxuma ozenzekelayo owakhelwe ngaphakathi. Iivalvu zineekhonkco zokungenisa umoya kunye nomngxuma wokukhupha umoya/ukukhupha umoya kumngxuma wevalvu. Uqhagamshelwano lokungenisa umoya kunye nomngxuma wokukhupha umoya lungasetyenziselwa ukuqinisekisa ukutywina kwevalvu kwi-intanethi.

• Ikhuselekile emlilweni kwi-API 607

• Uyilo oluchasene nokungashukumi

• Isiqu esilwa nokuqhushumba

• Ibhola efakwe kwiTrunnion

• Isihlalo Esithwele Imithwalo Esisentwasahlobo Esidadayo

• Umzimba Owahlulweyo, Ukungena Ekugqibeleni

Uyilo kunye noMveliso:I-API 6D, BS 5351
Ubuso ngobuso:API B16.10, API 6D, EN 558, DIN 3202
Uqhagamshelo Lokuphela:ASME B16.5, ASME B16.25, EN 1092, GOST 12815

I-NSEN ilandela ngokungqongqo iinkonzo zokulungisa zasimahla, ukutshintshwa kwasimahla kunye nokubuyiselwa kwasimahla kwiinyanga ezili-18 emva kokuba ivalvu ingasebenzi okanye iinyanga ezili-12 emva kokufakwa nokusetyenziswa kwipayipi emva kokusebenza kwangaphambili (ekuza kuqala). 

Kwimeko apho ivalvu iye yawa ngenxa yengxaki yomgangatho ngexesha lokusetyenziswa kwipayipi ngexesha lewaranti yomgangatho, i-NSEN iya kubonelela ngenkonzo yewaranti yomgangatho yasimahla. Inkonzo ayizukuphela de kube ukusilela kulungisiwe kwaye ivalvu iyasebenza kwaye umthengi utyikitye ileta yokuqinisekisa.

Emva kokuphela kwexesha elichaziweyo, i-NSEN iqinisekisa ukubonelela abasebenzisi ngeenkonzo zobugcisa ezisemgangathweni ngexesha nanini na xa imveliso ifuna ukulungiswa nokugcinwa.
