Qinisekisa izinqubo ezingavinjwanga: Iqhaza nokubaluleka kwamavalvu embulunga ajwayelekile yaseShayina ekuthuthukiseni ukuphepha kwesistimu yamapayipi
Qinisekisa izinqubo ezingavinjwanga: Iqhaza nokubaluleka kwamavalvu embulunga ajwayelekile yaseShayina ekuthuthukiseni ukuphepha kwesistimu yamapayipi
Ezimisweni zamapayipi ezimboni eziyinkimbinkimbi, amavalvu ahlukahlukene adlala indima ebalulekile, esebenza njengenhliziyo nemithambo yegazi elawula ukugeleza kwegazi, eqinisekisa ukuthi uketshezi lugeleza ngesikhathi esifanele, indawo, kanye nenani. Phakathi kwama-valve amaningi, i-valve yaseShayina ejwayelekile ye-flange globe isiyingxenye ebalulekile yokuqinisekisa ukusebenza okuphephile kwezinhlelo zamapayipi ngenxa yomklamo wayo oyingqayizivele nokusebenza okuphakeme.
I-valve yeglobhu ye-flange ejwayelekile yaseShayina iyi-valve yembulunga ekhiqizwe ngokuya ngamazinga kazwelonke. Ixhunywe epayipini ngokuxhumeka kwe-flange ukuze kuzuzwe ukuvuleka nokuvalwa kwendlela yoketshezi. Lolu hlobo lwe-valve luklanywe kahle futhi lungafinyelela ukulawula ukugeleza okunembile ngokusebenza kwe-stem ephakamisayo ngaphandle kokushintsha isiqondiso sokugeleza. Isakhiwo sayo sihlanganisa umzimba we-valve, ikhava ye-valve, i-valve disc, isiqu se-valve, nendandatho yokuvala, futhi ingxenye ngayinye inomthwalo wemfanelo obalulekile wokuqinisekisa ngokuhlanganyela ukusebenza okuvamile kwe-valve.
Ngokomsebenzi, ivalvu yeglobhu ye-flange ejwayelekile yaseShayina "ingumnakekeli" obaluleke kakhulu ezinhlelweni zamapayipi. Okokuqala, ingakwazi ukulawula izinga lokugeleza koketshezi. Njengompheki onolwazi okwazi kahle ukushisa, ivalve yokuvala ilawula ngokunembile izinga lokugeleza nezinga lokugeleza koketshezi ngokulungisa ukuvuleka, ngaleyo ndlela ihlangabezane nezidingo eziqondile zokulawula uketshezi ohlelweni lokukhiqiza. Okwesibili, inokusebenza okuhle kakhulu kokuvala. Kungakhathaliseki ukuthi kusendaweni enengcindezi ephezulu noma enengcindezi ephansi, ama-valve embulunga angagcina ukuvala kahle futhi avimbele ukuvuza, ngenxa yesakhiwo sokuvala esiklanywe ngokucophelela kanye nezinto zokuvala zekhwalithi ephezulu. Ngaphezu kwalokho, futhi inomsebenzi omuhle wokusika. Uma kudingekile ukumisa noma ukushintsha ukugeleza koketshezi, i-valve yokuvala ingasabela ngokushesha ukuze kufinyelelwe ukunqanyulwa koketshezi, ngaleyo ndlela inikeze ukuvikeleka kokuphepha ekugcinweni kwemishini noma ezimeni eziphuthumayo.
Ngokubaluleka, ama-valve embulunga ye-flange ejwayelekile yaseShayina abalulekile ekuqinisekiseni ukusebenza okuphephile kwezinhlelo zamapayipi. Isibonelo, ezimbonini ezifana ne-petroleum namakhemikhali, izinhlelo zamapayipi ngokuvamile zidinga ukubhekana nezinga lokushisa eliphezulu, umfutho ophezulu, kanye nemithombo yezindaba egqwala kakhulu. Kulokhu, ukuzinza nokuqina kwe-valve yokuvala kubaluleke kakhulu. Ukukhetha ivalvu yokuvala efanelekile kungaqinisekisa ukuthi uhlelo lwamapayipi lusasebenza ngokuphepha nangokuzinza ngaphansi kwalezi zimo ezimbi kakhulu. Ngaphezu kwalokho, ama-valve embulunga nawo angasetshenziswa ukuvimbela ukugeleza emuva nokuvikela imishini eya phansi emthelela wokuguquguquka kwengcindezi ekhuphukayo.
Ngaphezu kokusebenza ngaphansi kwezimo ezijwayelekile, ama-valve embulunga ye-flange ejwayelekile yaseShayina nawo adlala indima ebalulekile ezimeni eziphuthumayo. Lapho ipayipi ligqabuka noma livuza, ivalvu yokuvala ingavaleka ngokushesha ukuze kuvinjelwe ukuvuza okwengeziwe kwezinto eziyingozi, ngaleyo ndlela kugwenywe ukungcoliswa kwemvelo okungaba khona kanye nokulimala komuntu. Phakathi naleso sikhathi, ngokusebenzisana nezinye izinto zokuphepha ezifana nama-valve okunciphisa ingcindezi, ama-disc okuphuka, njll., kungakhiwa uhlelo olubanzi lokuvikela ukuphepha.
Kafushane, ama-valve eglobhu ama-flange ajwayelekile aseShayina adlala indima ebalulekile ekuqinisekiseni ukusebenza ngokuphephile kwezinhlelo zamapayipi. Ikhono layo lokulawula elinembile, ukusebenza kahle kakhulu kokuvala, nomsebenzi wokusika onamandla kuyenza isebenze kahle kakhulu ezindaweni ezihlukahlukene eziyinkimbinkimbi. Ukuqonda indima nokubaluleka kwayo kubaluleke kakhulu ekuqinisekiseni ukuphepha nokusebenza kahle kokukhiqizwa kwezimboni.
Ngokuthuthuka okuqhubekayo komkhakha wezimboni kanye nenqubekelaphambili yezobuchwepheshe, sinesizathu sokukholelwa ukuthi ama-valve embulunga ye-flange ejwayelekile yaseShayina azoba nokusebenza okuphakeme kanye nohlu olubanzi lwezinhlelo zokusebenza. Ngokuqhubeka sithuthukisa ubuchwepheshe bokukhiqiza kanye namazinga esayensi yezinto ezibonakalayo, singanikeza iziqinisekiso eziphephile nezithembekile zezinhlelo zamapayipi ezimbonini.
