I-Valve yinxalenye yolawulo lwenkqubo yokuhanjiswa kwamanzi, kunye ne-cut-off, ummiselo, i-diversion, ukuthintela ukuthintela ukuhamba, ukulawulwa koxinzelelo, i-shunt okanye i-overflow relief relief kunye neminye imisebenzi.Ukuhlelwa ngokomsebenzi kunye nesicelo kunje kungezantsi:
I-1.I-valve ye-Truncation: i-valve ye-truncation ikwabizwa ngokuba yi-valve evaliweyo, indima yayo kukudibanisa okanye ukunciphisa umbhobho ophakathi.Okubandakanya iivalve zesango, iivalve zeglowubhu, iivalve zeplagi, iivalve zebhola, iivalve zebhabhathane kunye ne-diaphragm valves, njl.
I-2.I-valve yokuHlola: Ivalve yokukhangela iyaziwa nangokuthi i-valve yendlela enye okanye engabuyiyo.Umsebenzi wayo kukuthintela ukuhamba kombhobho ophakathi ngasemva.
3.Ivalve yokhuseleko: Umsebenzi wevalve yokhuseleko kukuthintela uxinzelelo oluphakathi kumbhobho okanye isixhobo ekugqithiseni ixabiso elichaziweyo, ukuze kufezekiswe injongo yokhuseleko lokhuseleko.
4.Ivalve yokulawula: kubandakanywa ivalve yokulawula, ivalve ye-throttle kunye nevalve yokunciphisa uxinzelelo, umsebenzi wayo · kukulungelelanisa uxinzelelo lwe-medium, flow and other parameters.
I-5.I-valve ye-Shunt: ibandakanya iindidi ezahlukeneyo zokusabalalisa kunye nezibatha, njl., Umsebenzi wayo kukusabalalisa, ukwahlula okanye ukuxuba okuphakathi kwipayipi.
Xa ivalve isetyenziswa kumgca wonikezelo lwamanzi, yeyiphi indawo yokukhetha ukuba luhlobo luni lwevalve, ngokubanzi ngokwemigaqo elandelayo:
1. Xa i-diameter yombhobho ingekho ngaphezu kwe-50mm, ivalve yeglowubhu kufuneka isetyenziswe, kwaye xa ububanzi bombhobho bungaphezulu kwe-50mm, ivalve yesango kunye nevalve yebhabhathane kufuneka isetyenziswe.
2.Xa ukuhamba kunye nesicinezeli samanzi kufuneka kulungiswe, ivalve elawulayo, iglowubhu kufuneka isetyenziswe.
3. Ukuba ukuxhathisa ukuhamba kwamanzi kuncinci (njengombhobho wokufunxa impompo yamanzi), ivalve yesango kufuneka isetyenziswe
4. Ivalve yesango kunye nevalve yebhabhathane kufuneka isetyenziswe kwicandelo lombhobho apho ukuhamba kwamanzi kufuneka kujikelezwe kabini, kwaye ivalve yeglowubhu mayingasetyenziswa.
5. Ivalve yebhabhathane kunye nevalve yebhola kufuneka isetyenziswe kwiindawo ezinendawo encinci yokufaka
6. kwicandelo lombhobho elihlala livulekile kwaye livaliwe, kuyafaneleka ukusebenzisa ivalve yeglowubhu
7.Ivalve esebenza ngeendlela ezininzi kufuneka isetyenziswe kumbhobho wokukhupha amanzi onombhobho omkhulu
8.Iivalvu zokutshekisha ziya kufakelwa kula macandelo alandelayo emibhobho:Kumbhobho wokungena wesifudumezi-manzi esivaliweyo okanye isixhobo sokusebenzisa amanzi;Umbhobho okhupha impompo yamanzi; Kwicandelo lombhobho wokuphuma wetanki yamanzi, inqaba yamanzi kunye nedama elinyukayo lalo mbhobho omnye.
Qaphela: Akuyimfuneko ukufakela ii-valve zokujonga kumacandelo emibhobho axhotyiswe ngabathinteli bokubuyela umva.
