Kungani Ama-Valve Okuvala Okusheshayo Ebalulekile Emikhumbini Yasolwandle

Ezinqoleni zomkhumbi, izinhlelo zokuphepha azinazo izinketho—zisindisa impilo. Phakathi kwalezi zinhlelo,ama-valve okuvala okusheshayozidlala indima ebalulekile ekuvikeleni imikhumbi, abasebenzi, kanye nempahla ezingozini zomlilo kanye nezikhukhula. Eklanyelwe ukuvala uphethiloli noma uwoyela ngokushesha, ama-valve okuvala okusheshayo ayisici esibalulekile kubunjiniyela besimanje basolwandle.

Impendulo Esheshayo Ezimweni Eziphuthumayo

Inhloso eyinhloko yevalvu yokuvala okusheshayo isivinini. Uma kwenzeka umlilo, ukuvuza kukaphethiloli, noma ukuqhekeka kwepayipi, lawa mavalvu angavala ukugeleza kukaphethiloli noma uwoyela wokugcoba ngemizuzwana embalwa. Lokhu kuhlukaniswa okusheshayo kuvimbela uphethiloli ekukhuliseni umlilo futhi kunciphisa kakhulu ingozi yokuqhuma.Ngokungafani nama-valve aqhutshwa ngesandla atholakala ezindaweni eziyingozi, ama-valve okuvala okusheshayo angasetshenziswa kude, okuvumela amalungu eqembu ukuthi enze okuthile ngaphandle kokungena ezindaweni eziyingozi.

Ukuphepha Komlilo Okuthuthukisiwe Ebhodini

Izinjini zasolwandle zithembele kakhulu ezinhlelweni zikaphethiloli kanye nokugcoba. Uma umlilo uqubuka egumbini lenjini, ukugeleza kukaphethiloli okungalawuleki kungashintsha ngokushesha isigameko esilawulekayo sibe yinhlekelele. Ama-valve okuvala okusheshayo ayasiza:

• ①Nciphisa ukunikezwa kukaphethiloli ezinjinini nasezinjinini ezikhiqiza uphethiloli

• ②Vimbela uwoyela ekusabalaliseni amalangabi

• ③Sekela amasu okulawula umlilo

Lo msebenzi ubaluleke kakhulu ezindaweni ezivalekile lapho umlilo usakazeka khona ngokushesha.

Ukuhambisana neMithethonqubo Yomhlaba Wonke Yezolwandle

Ama-valve okuvala okusheshayo akuyona nje indlela engcono kakhulu—ayindlelaimfuneko yokulawulaIzindinganiso zomhlaba wonke ezifana nalezi:I-SOLAS (Ukuphepha Kokuphila Olwandle).Imithethonqubo ye-IMO.Imithetho yenhlangano yokuhlela (i-DNV, i-ABS, i-LR, i-BV, njll.)

Kudingeka ukuthi kufakwe ama-valve okuvala okusheshayo emathangini kaphethiloli kanye nemigqa yokuhlinzeka. Ukufaka ama-valve aqinisekisiwe kuqinisekisa ukuhambisana ngesikhathi sokuhlolwa futhi kugwema izinhlawulo ezibizayo noma ukubambezeleka kokusebenza.

Ukusebenza Okukude Nokuphepha Okungaphumeleli

Ama-valve amaningi okuvala okusheshayo aklanywe ngalezi zinto ezilandelayo:Ukusebenza kwe-remote mechanical, pneumatic, noma hydraulic.Izindlela zokuvala ezigcwele entwasahlobo noma ezisizwa amandla adonsela phansi

Lokhu kusho ukuthi ivalvu izovala ngokuzenzakalelayo uma kwenzeka ukulahleka kwamandla noma ukwehluleka kokulawula, okunezela ungqimba olwengeziwe lokuphepha. Ngisho nangaphansi kwezimo ezinzima zasemanzini—ukudlidliza, ukushisa, noma ukugqwala—ivalvu ihlala ithembekile.

Ukunciphisa Izingozi Zemvelo Nezokusebenza

Ukuvuza kukaphethiloli olwandle kungabangela umonakalo omkhulu emvelweni futhi kuholele ezinhlawulweni ezinkulu. Ama-valve okuvala ngokushesha anciphisa:Ukuchitheka kwamafutha.Isikhathi sokungasebenzi kwemishini.Izindleko zokulungisa nokuhlanza

Ngokuhlukanisa izingxenye ezonakele ngokushesha, amaqembu angalawula kangcono izinhlelo ezisemotweni.

Ukusekela Ukugcinwa Nokulungiswa Okuphephile

Ngesikhathi sokulungiswa, amavalvu okuvala okusheshayo avumela opharetha ukuthihlukanisa amathangi kaphethiloli namapayipi ngokuphephile, kunciphisa ingozi yokukhishwa ngengozi. Lokhu kwenza ukuhlolwa okuvamile kanye nokulungiswa okuphuthumayo kube okuphephile futhi okuphumelelayo kakhudlwana.
