I-valve yepulaki yohlobo lomkhono idizayini ethile yepulaki yepulaki lapho ipulaki eyisilinda noma ecijile ngaphakathi komzimba wevalvu isetshenziswa ukulawula ukugeleza koketshezi.Ipulaki inengxenye yokusika eqondana nephaseji lokugeleza lapho isendaweni evulekile, evumela ukudlula koketshezi, futhi ingajikiswa ukuze ivimbe ngokuphelele ukugeleza lapho isendaweni evaliwe.Lolu hlobo lwevalvu lwaziwa ngokuvala kwalo okuqinile. -amandla okuvala, ukwehla komfutho omncane, kanye nokusetshenziswa okuguquguqukayo kuzo zonke izinhlobo zezinhlelo zokusebenza, okuhlanganisa inqubo kanye nezinhlelo zezimboni ezibamba uketshezi namagesi.Ama-valve ohlobo lwe-sleeve plug avame ukusetshenziswa ezimbonini ezifana nowoyela negesi, i-petrochemical, amakhemikhali, nezinye izinhlelo izimboni ngenxa yokwethembeka nekhono lazo lokuphatha izinhlobo ezahlukene zoketshezi.Lawa mavalvu angase futhi abe nezici ezifana nepulaki eligcotshisiwe, ukulinganisa ingcindezi, nezinto zokwakha ezihlukene ukuze zivumelane nezidingo zenqubo ethile nezimo zokusebenza.Uma udinga ulwazi oluthe xaxa mayelana namapulaki ohlobo lwemikhono noma unemibuzo ethile mayelana nokusetshenziswa kwawo noma ukugcinwa kwawo, zizwela. khululeka ukubuza.
1. Ukwakheka komkhiqizo kuyinto enhle kakhulu, ukubekwa uphawu okuthembekile, impilo ende yokuvala, ukusebenza okuphakeme, ukumodela ngokuhambisana nenqubo yobuhle.
2. ngomkhono othambile kanye nokuxhumana kwepulaki lensimbi ukuze kuqinisekiswe ukuvaleka, okuguquguqukayo okuqinile.
3. i-valve ingafakwa ngokugcwele, ingalawulwa yisiqondiso sokufaka;I-valve incane ngosayizi futhi ayinazo izidingo ezikhethekile zendawo yokufaka.
4. i-valve ingasetshenziselwa ukugeleza kwezindlela ezimbili, kulula ukuyikhiqiza ibe ifomu le-multi-pass, kulula ukulawula ukuhamba kwemidiya yamapayipi.
5. kunodebe lwensimbi oluyi-360° oluyingqayizivele phakathi komkhono nomzimba we-valve, olungavikela futhi lulungise umkhono, ukuze ungazungezi nepulaki, futhi lungavala umkhono nendawo yokuthintana nomzimba wevalvu okuthembeke kakhulu. futhi uzinzile.
6. lapho ipulaki izungeza, izokwenwa indawo yokuvala, inikeze umsebenzi wokuzihlanza, ofanele imidiya yokukala ewugqinsi futhi elula.
7. i-valve ayinakho umgodi wangaphakathi wokuqongelela okuphakathi.
8. i-valve kulula ukuyikhiqiza ibe yisakhiwo esingashi.

Isevisi yokuthengisa emva kokuthengisa ye-valve yebhola elintantayo ibaluleke kakhulu, ngoba isevisi efika ngesikhathi futhi ephumelelayo ngemva kokuthengisa ingaqinisekisa ukusebenza kwayo kwesikhathi eside nokuzinzile.Okulandelayo okuqukethwe kwesevisi yangemuva kokuthengisa kwamanye ama-valve amabhola antantayo:
1.Ukufakwa kanye nokugunyazwa: Abasebenzi besevisi yangemuva kokuthengisa bazoya kusayithi ukuze bafake futhi balungise iphutha le-valve yebhola elintantayo ukuze baqinisekise ukusebenza kwayo okuzinzile nokujwayelekile.
I-2.Ukugcinwa: Gcina njalo i-valve yebhola elintantayo ukuze uqinisekise ukuthi isesimweni esihle kakhulu sokusebenza futhi unciphise izinga lokuhluleka.
3.Ukuxazulula inkinga: Uma i-valve yebhola elintantayo ihluleka, izisebenzi zesevisi yangemuva kokuthengisa zizokwenza ukuxazulula inkinga endaweni ngesikhathi esifushane kakhulu ukuze kuqinisekiswe ukusebenza kwayo okuvamile.
4.Ukuvuselelwa nokuthuthukiswa komkhiqizo: Ngokuphendula ezintweni ezintsha kanye nobuchwepheshe obusha obuvela emakethe, abasebenzi besevisi yangemuva kokuthengisa bazoncoma ngokushesha ukuvuselela nokuthuthukisa izixazululo kumakhasimende ukuze bawanikeze imikhiqizo yamavalvu engcono.
5. Ukuqeqeshwa kolwazi: Izisebenzi zesevisi yangemuva kokuthengisa zizohlinzeka ngokuqeqeshwa kolwazi lwama-valve kubasebenzisi ukuze kuthuthukiswe izinga lokuphatha nokunakekela abasebenzisi besebenzisa ama-valve amabhola antantayo.Ngamafuphi, isevisi yangemuva kokuthengisa ye-valve yebhola elintantayo kufanele iqinisekiswe kuzo zonke izinkomba.Kungale ndlela kuphela engaletha abasebenzisi umuzwa ongcono nokuphepha kokuthenga.
