Ukuchazwa okuningiliziwe kwendlela efanele yokusebenzisa i-valve

Ukulungiselela ngaphambi kokusebenza

Ngaphambi kokusebenzisa i-valve, kufanele ufunde imiyalo yokusebenza ngokucophelela. Ngaphambi kokusebenza, kufanele ucace mayelana nokuqondiswa kokugeleza kwegesi, kufanele unake ukubheka ukuvulwa kwe-valve ukuvula nokuvala izimpawu. Hlola ukubukeka kwe-valve ukubona ukuthi ngabe i-valve ingumanzi, uma kukhona umswakama wokuwomisa ukwelashwa; Uma kutholakale ukuthi kunezinye izinkinga okufanele zibhekwe ngendlela efike ngesikhathi, ngeke zisetshenziswe ngokwehluleka. Uma i-valve kagesi ingaphandle kwensizakalo isikhathi esingaphezu kwezinyanga ezintathu, i-clutch kufanele ihlolwe ngaphambi kokuqala, qiniseka ukuthi isibambo sisesimweni sencwadi, bese uhlola ukufakwa, ukuqondisa kanye ne-wiring yemoto.

Ukusebenza kahle kwama-valves abhaliwe

Ama-valves ngesandla ama-valves asetshenziswa kakhulu, kanye nezibambo zawo noma izibambo zenzelwe ngokuya ngamandla ajwayelekile womuntu, kucatshangelwa amandla endawo yokubopha kanye namandla okuvala adingekayo. Ngakho-ke, awukwazi ukusebenzisa i-lever ende noma isandla eside ukuhambisa ipuleti. Abanye abantu bajwayele ukusetshenziswa kwesandla sePlate, kufanele banake ngokuqinile ukuvulwa kwe-valve kufanele kusetshenziselwe ukuphoqa bushelelezi, bagweme ukuvulwa nokuvalwa kwe-valve, amandla kufanele kube mnandi. Okunye ukuvulwa komthelela nokuvalwa kwezinto eziphakeme ze-valve ye-valve kucatshangelwe ukuthi le miphumela nama-general valves ayinakulingana neqembu lezigelekeqe.

Lapho i-valve ivulekile ngokuphelele, isandla sesandla kufanele sibukwe kancane, ukuze imicu phakathi kokuqinile, ukuze ingathululi umonakalo. IngomaneI-STEM STEM Gate Valves,Ukukhumbula okuvuleke ngokuphelele futhi kuvalwe ngokuphelele lapho isikhundla sesiqu, ukugwema ukuvula ngokuphelele lapho umthelela esikhungweni esifile. Futhi kulula ukubheka ukuthi kujwayelekile yini uma kuvalwa ngokuphelele. Uma ihhovisi le-valve livaliwe, noma i-spool seal inyuswe phakathi kwemfucumfucu emikhulu, isikhundla esivaliwe ngokuphelele kufanele iguqulwe. Ukulimala kwe-valve ebopha uphawu noma indawo ye-valve handsheel.

Isibonakaliso se-Valve Open: I-Valve ye-Ball,I-valve ye-butterfly eqinile, xhuma isigaxa se-valve stem ephezulu ye-groove parallel kuya esiteshini, okukhombisa ukuthi i-valve isesimweni esivulekile ngokuphelele; Lapho isigaxa se-valve sijikeleze i-90 ° ngakwesobunxele noma kwesokudla, i-groove ivela ku-perpendicular esiteshini, okukhombisa ukuthi i-valve isesimweni esivalelwe ngokuphelele. Amanye ama-valves ebhola, ama-valves we-butterfly, ama-valves axhumene nawo ahambisane nokufana okuhambisanayo ukuze uvule, mpo ngokuvalwa. Ama-valves amathathu, ama-valves anezindlela ezine kufanele asebenze ngokuya ngokumaka kokuvula, ukuvala nokubuyisela emuva. Ngemuva kokuthi umsebenzi usuqediwe, isibambo esishukumisekayo kufanele sisuswe.

Ukusebenza okulungile kwama-valve ama-Check

Ukuze ugweme amandla anomthelela omkhulu owenziwe ngesikhathi sokuvalai-rubber ehlelwe i-valve, i-valve kumele ivalwe ngokushesha, ngaleyo ndlela ivikele ukwakheka kwe-velocity enhle yangemuva, okuyimbangela yokucindezela komthelela owakhiwe lapho i-valve ivalwa kungazelelwe. Ngakho-ke, ijubane lokuvala le-valve kufanele lifaniswe kahle nezinga lokubola kwe-Downtruam Medium.

Uma i-velocity ye-medium egelezayo iyahlukahlukahlukahlukahluka, ubuncane bokugeleza velocity akwanele ukuphoqa into yokuvala iye esitobhini esimenyezelayo. Kulokhu, ukunyakaza kwento yokuvala kungathathwa ngaphakathi kohlu oluthile lokushaywa kwalo. Ukudlidliza okusheshayo kwento yokuvala kungenza izingxenye ezihambayo ze-valve ziguge ngokushesha okukhulu, okuholele ekuhlulekeni kwe-valve ngaphambi kwesikhathi. Uma i-medium idonsa kanzima, ukudlidliza okusheshayo kwento yokuvala kuyabangelwa ukuphazamiseka okuphakathi okuthe xaxa. Nomaphi lapho kunjalo, hlola ama-valves kufanele atholakale lapho kuncishiswa khona ukuphazamiseka okuphakathi.
