IiNqaku eziPhakamileyo zoKhetho lweValve

1. Chaza injongo yeivalvekwizixhobo okanye isixhobo

Chonga iimeko zomsebenzi zevalve: Uhlobo lwendlela esebenzayo, i-cinezelo, iqondo lobushushu lokusebenza kunye nendlela yokulawula.

2. Khetha ngokuchanekileyo uhlobo lwe-valve

Ukukhetha ngokuchanekileyo uhlobo lweValve yinto eyimfuneko kumyili wokuqonda ngokupheleleyo inkqubo yemveliso kunye neemeko zokusebenza. Xa ukhetha uhlobo lwevelve, uMyili kufuneka kuqala aqonde iimpawu zesakhiwo kunye nokusebenza kwevalve nganye.

3. Chonga unxibelelwano lwe-valve

Phakathi konxibelelwano oluqhelekileyo, uqhagamshelo lweflenge, kunye nonxibelelwano lokuphela kwe-welding, ezimbini zokuqala zezona zisetyenziswa kakhulu. I-valves enamatyala ikakhulu ziivali ze-diameter othethiweyo ngezantsi kwe-50mm. Ukuba ububanzi bukhulu kakhulu, ukufakelwa kunye nokutywinwa kwenxalenye yokudibanisa kuya kuba nzima kakhulu. Iivalde ezivuthayo zilungele ukufaka kunye nokuhlanganisana, kodwa zinzima kwaye zibiza kakhulu kune-valves ezixineneyo, ngoko ke zilungele i-valding ye-pihomeli kunye noxinzelelo. Unxibelelwano lwe-welding lulungele imithwalo enzima kwaye ithembekile ngakumbi kunxibelelwano oluxutywe. Nangona kunjalo, kunzima ukukhuthaza kwaye iphinde iphinde iphinde idityaniswe nge-welven, ke ukusetyenziswa kwayo kunqunyelwe kwizihlandlo apho kunokuqhuba ngokuxhomekeke kwixesha elide, okanye apho iimeko zininzi khona kwaye amaqondo obushushu aphezulu.

4. Ukukhetha izinto ze-veli

Xa ukhetha umxholo weqokobhe leValve, amalungu angaphakathi kunye nomphezulu wokutywina, ukongeza ekuqwalaseleni iipropathi zomzimba (iqondo lobushushu) kunye neendawo eziphakathi (kunye okanye ngaphandle kwamasuntswana aqinileyo) nazo kufuneka zibanjwe. Ukongeza, kuyimfuneko ukubhekisa kwimigaqo efanelekileyo kaRhulumente kunye nesebe lomsebenzisi. Ukukhetha ngokuchanekileyo nangokufanelekileyo kwezinto ezibonakalayo ze-veve kunokufumana olona hlobo lwenkonzo yezoqoqosho kunye nokusebenza kakuhle kwevalve. Ukulandelelana kwe-valve ye-valve: kuqulatha i-iron-carbon yentsimbi-intsimbi yentsimbi, kunye nolandelelwano lokukhetha i-ring lokukhala kwentsimbi:

5. Enye

Ukongeza, inqanaba lokuhamba kunye nenqanaba loxinzelelo lokuqukuqela i-fast igijimeza ivalve kufuneka igqitywe, kwaye ivalve efanelekileyo kufuneka ikhethwe kusetyenziswa idatha ekhoyo (njengeI-Valve ikhathalogu kwi-tetalog, iisampulu zemveliso, njl. Njl.).
