Ukuhlolwa kwengcindezi ye-valve kuzohambisana nezimiso kanye nezindaba ezidinga ukunakwa ohlelweni lokukhiqiza ama-valve angu-16 kuyinkimbinkimbi futhi elula, ukukhiqizwa okuvamile kwama-valve afana ne-valve yesango, i-valve yebhola, i-globe valve, i-butterfly valve, i-valve yokuhlola, umjikelezo wokukhiqiza ngokuvamile. ezinsukwini ezintathu, amavalvu okukhiqiza amahle kufanele adlule ekuhlolweni kokusebenza okuhlukahlukene, okuhlanganisa * * okubalulekile ukuhlola ukuhlola. Ukuhlolwa kwengcindezi ukuhlola ukuthi ingabe inani lokucindezela levalvu lingathwala liyahlangabezana yini nezidingo zemithetho yokukhiqiza, ukuhlolwa komfutho we-valve jikelele kufanele kuhambisane nemigomo nezindaba ezilandelayo ezidinga ukunakwa:
Ukukhiqizwa kwama-valve kuyinqubo eyinkimbinkimbi futhi elula. Umjikelezo wokukhiqiza wama-valve ajwayelekile njengama-valve esango, ama-valve ebhola, ama-globe valves, ama-butterfly valve nama-sheke valve ngokuvamile uthatha izinsuku ezintathu. Ukukhiqizwa kwama-valve kufanele kuhlolwe ngezivivinyo ezihlukahlukene zokusebenza, phakathi kwazo ukuhlolwa okubaluleke kakhulu ukuhlolwa kwengcindezi. Ukuhlolwa kwengcindezi ukuhlola ukuthi ingabe inani lokucindezela levalvu lingathwala liyahlangabezana yini nezidingo zemithetho yokukhiqiza, ukuhlolwa komfutho we-valve jikelele kufanele kuhambisane nemigomo nezindaba ezilandelayo ezidinga ukunakwa:
(1) Ngaphansi kwezimo ezijwayelekile, i-valve ayihlolwa amandla, kodwa umzimba we-valve kanye nesembozo se-valve ngemva kokulungiswa noma ukulimala kokugqwala kufanele kuhlolwe amandla. Nge-valve yokuphepha, ingcindezi eqhubekayo kanye nengcindezi yokubuyisela nokunye ukuhlolwa kufanele kuhambisane nencazelo kanye nezinhlinzeko zezinqubo ezifanele.
(2) Amandla nokuqina kwevalvu kufanele kuhlolwe. I-low-pressure valve spot isheke i-20%, efana nengafaneleki kufanele ihlolwe ngu-100%; Amavalvu omfutho ophakathi nendawo nophezulu kufanele ahlolwe ngo-100%.
(3) Ngesikhathi sokuhlolwa, i-valve kufanele ifakwe ngendlela yokuhlola kalula.
(4) Kumavalvu asesimweni soxhumano olushiselwe, uphawu oluyi-conical noma i-O-ring seal lungasetshenziselwa ukuhlola ingcindezi lapho ukuhlolwa kwengcindezi ngepuleti eliyimpumputhe kungenzeki.
(5) ukuhlolwa kwe-hydraulic kuzozama ukuqeda umoya we-valve.
(6) Ukucindezela kufanele kukhuphuke kancane kancane ngesikhathi sokuhlolwa, futhi ukucindezela okusheshayo nokuzumayo akuvunyelwe.
(7) Ukuhlolwa kwamandla kanye nobude besikhathi sokuhlolwa kokuvala ngokuvamile imizuzu emi-2-3, amavalvu abalulekile futhi akhethekile kufanele athathe imizuzu emi-5. Isikhathi sokuhlola i-valve ye-diameter encane singaba sifushane ngokufanayo, isikhathi sokuhlola i-diameter enkulu singaba side ngokulinganayo. Ngesikhathi sokuhlolwa, uma ungabaza, isikhathi sokuhlola singanwetshwa. Ngesikhathi sokuhlolwa kwamandla, ungavumeli umzimba nekhava ukuthi kujuluke noma kuvuze. Ukuhlolwa kokuvala uphawu, i-valve ejwayelekile ikanye kuphela, i-valve yokuphepha, i-valve yomfutho ophezulu kanye namanye ama-valve aluhlaza adinga ukwenziwa kabili. Ngesikhathi sokuhlolwa, ingcindezi ephansi, i-diameter enkulu engabalulekile ama-valve nama-valve anezinhlinzeko ezivumela ukuvuza avunyelwe ukuba kube nokulandela ukuvuza okwenzekayo; Ngenxa yezidingo ezihlukene zama-valve wendawo yonke, ama-valve esiteshini samandla, ama-Marine valves namanye ama-valve, izidingo zokuvuza kufanele zenziwe ngokuhambisana nemithetho efanele.
(8) I-throttle valve ayivalwanga ukuhlolwa kokuvaleka, kodwa kufanele ibe ukuhlolwa kwamandla nokupakisha kanye nokuhlolwa kokuvala i-gasket.
(9) Ekuhlolweni komfutho, amandla okuvala amavalvu avumela kuphela amandla avamile omzimba womuntu ukuba avale; Akuvunyelwe ukusebenzisa amandla ngezinsimbi noma amanye amathuluzi (ngaphandle kwama-torque wrenches). Uma ububanzi besondo lesandla bukhulu kuno-320mm, abantu ababili bavunyelwe ukulivala ndawonye.
(10) Ivalvu enophawu olungaphezulu kufanele ikhishwe lapho kupakishwa khona ukuze kuhlolwe ukuvaleka. Ngemuva kokuthi uphawu olungaphezulu luvaliwe, hlola ukuthi akukho yini ukuvuza. Uma uhlola ngegesi, gcwalisa ibhokisi lokugxusha ngamanzi ukuze lihlolwe. Ungavumeli uphawu olungaphezulu lube sesimweni esiseduze lapho upakisha ukuhlolwa kokuqina.
(11) lapho ivalvu inomshini wokushayela, lapho kuhlolwa ukuvaleka kwayo, idivayisi yokushayela kufanele isetshenziselwe ukuvala ivalvu ukuze kuhlolwe ukuvaleka. Idivayisi yokushayela ngesandla, kufanele futhi isetshenziselwe ukuvala ukuhlolwa kophawu lwevalvu.
(12) Ukuhlolwa kwamandla nokuhlolwa kokuvala okufakwe ku-valve enkulu yokudlula i-valve, emandleni ama-valve amakhulu nokuhlolwa kokuvala; Lapho i-valve enkulu yokuvala ivuliwe, kufanele futhi ivulwe ngokufanele.
(13) Ngesikhathi sokuhlolwa kwamandla evalve yensimbi ewukhonkolo, isando sethusi kufanele sisetshenziselwe ukuthinta umzimba wevalvu kanye nesembozo sevalvu ukuhlola ukuthi akukho yini ukuvuza.
(14) Uma kuhlolwa ivalvu, indawo evalekayo yevalvu ayivunyelwe ukuthi igcotshwe ngaphandle kokuthi indawo yokuvala yevalvu yepulaki ivunyelwe ukuthi igcotshwe ngamafutha.
(15) Ngesikhathi sokuhlolwa kwengcindezi ye-valve, ukucindezela kwepuleti eliyimpumputhe ku-valve akufanele kube kukhulu kakhulu, ukuze kugwenywe ukuguquguquka kwe-valve futhi kuthinte umphumela wokuhlola (uma i-valve yensimbi yokusansimbi icindezelwe kakhulu, izolimala).
(16) Ngemva kokuqedwa kokuhlolwa komfutho we-valve, amanzi akuvalvu kufanele akhishwe ngesikhathi futhi asulwe, futhi irekhodi lokuhlola kufanele lenziwe.
