Ulawulo lweValve -Ukutshixa/Ukutsalwa

Uyilawula njani ingozi yokwenzakala xa uvula iiflange, utshintsha iivalvu, okanye ukhupha iipayipi zokulayisha?
Le misebenzi ingentla yonke yimisebenzi yokuvula imibhobho, kwaye iingozi zivela kwiinkalo ezimbini: okokuqala, iingozi ezikhoyo kumbhobho okanye kwizixhobo, kubandakanya isixhobo ngokwaso, inkqubo yenkqubo kunye nempembelelo enokubakho emva kokuvulwa; Okwesibini, kwinkqubo yokusebenza, njengempazamo yokuvula umbhobho ongengowokujoliswa, njl.njl., inokubangela umlilo, ukuqhuma, ukwenzakala komntu, njl.njl.

Ngoko ke, ngaphambi kokuba umbhobho uvulwe, izinto ezikwimbhobho/izixhobo kunye nenkqubo yoqhagamshelo lombhobho kufuneka zichongwe; Indlela yokuqinisekisa ukuba ingozi isusiwe; Yenza ukwahlukanisa amandla kunye nokucoca; Bonisa indawo yokusebenza kubaqhubi, jonga izixhobo kwaye uqinisekise ukwahlukanisa inkqubo;

Qinisekisa ukuba iimeko zokusebenza, iingozi kunye namanyathelo okulawula ayahambelana namaxwebhu emvume yokusebenza; Yenza amanyathelo angxamisekileyo emva kweengozi zabasebenzi kunye neengozi. Emva kokuba umbhobho uvuliwe, sebenzisa izikhuselo kunye neebhafu kangangoko kunokwenzeka; Umzimba kufuneka ube phezulu komsinga apho kunokwenzeka ukuvuza; Soloko ucinga ukuba umgca/izixhobo ziphantsi koxinzelelo; Nika inkxaso eyongezelelweyo njengoko kufuneka ukuthintela iingozi ezinokubakho "zokujikeleza" xa iivalvu, izihlanganisi okanye amalungu evuliwe; Musa ukususa iibholithi xa ukhulula iiflanges kunye/okanye imibhobho edibanisayo; Xa uvula umdibaniso, musa ukuwukhulula umsonto wendandatho ude uqhawulwe ngokupheleleyo ukuze ukwazi ukuqina xa kukho ukuvuza; Ukuba iflange kufuneka ivulwe kancinci ukuze kuncitshiswe uxinzelelo, ibholithi ekude nomsebenzisi kwiflange kufuneka ikhululwe kancinci ekuqaleni, ukuze ibholithi ekufutshane nomzimba igcinwe ixesha elithile, kwaye emva koko uxinzelelo kufuneka lukhutshwe kancinci. Ukwahlulwa kwamandla okusebenzayo,Ukutshixa/UkutsalwaUkuqinisekiswa kunye nokuthobela ukusebenza kwe-blind plugging kukwaqinisekisa ukunciphisa umngcipheko wokuvulwa kwemibhobho.
