Uyini umphongolo wamanzi wamaloli we-subsea

Amaphayiphu we-tanker subsea abizwa nangokuthi ama-pneumatic valve, ama-pneumatic subsea valves, ama-valve okuphuthumayo kanye nama-valve okuvala okuphuthumayo. Njengoba kube nezingozi zokuphepha ezihamba ngesivinini esikhulu kanye nasemhubheni zezimoto ezithwala izimpahla eziyingozi eChina ngonyaka we-2014, iminyango kahulumeni efanele iqinise ukwenganyelwa kwabakhiqizi bezimoto zamathangi njengamathangi kawoyela, kanye ne-GB 18564.1 ekhishwe yiKomidi Elincane Lezikebhe Zomakhalekhukhwini leNational Pressure IKomidi Lokumiswa Kwezikebhe -2006 “Izimoto Zamathangi Ezokuhamba Emgwaqweni Kwezimpahla Eziyingozi Zoketshezi Ingxenye 1: Izidingo Zobuchwepheshe Zamathangi Asemkhathini Wensimbi” ikubeka ngokusobala ukuthi ama-valve okuvala isimo esiphuthumayo kufanele afakwe ezansi ethangini ukuze kuthuthwe umgwaqo wezimpahla eziyingozi eziwuketshezi.
Isakhiwo nokwakheka:
I-tanker submarine valve akusona nje kuphela isiteshi esisetshenziswa ngamathangi ukulayisha nokuthulula uwoyela, kodwa futhi kuyisici esiyisisekelo esilawula ukuvulwa noma ukuvulwa kwesekethe likawoyela. Iqukethe kakhulu igobolondo, indlela yokufaka uphawu, indlela yokulawula, i-flange yokuxhuma ithangi kanye ne-flange ye-outlet. Indlela yokufaka uphawu ifakwe emzimbeni wethangi ngesikhathi sokufakwa futhi ixhunywe kupuleti langaphansi kwethangi ngethanga lokuxhuma ithangi; Umshini usebenzisa amandla okunwebeka entwasahlobo yensimbi engagqwali ukwenza uphawu lwe-axial othomathikhi ukuze i-valve engezansi ibe sesimweni esivaliwe ngokujwayelekile; imisebenzi yokuvula nokuvala yenziwa ngendlela yokulawula.
umsebenzi:
Lapho amandla angalinganiswanga wangaphandle evuselelwa, kungasuswa isiqu sangaphakathi sentwasahlobo ne-valve, ngaleyo ndlela kusikwe ipayipi likawoyela phakathi kwe-10S, kuqinisekiswe ukuphepha kwento esemotweni, ukuvimbela ukuvuza, ukuthungela nokuqhuma; ukuvikela abangani bomshayeli, izimpahla ezisemotweni, nokunye okuhlobene ngaphandle kwemoto Ukuphepha kwempahla nokuphila!
