Insimbi engagqwali evulekile yesitef

Lesi sigaxa esingenasici esikhuphukayo se-stem soft seal i-flange vate valog valve kusuka kuShengshi Huagong yehlukile kwi-valve ye-STEM efihliwe. Idizayini ekhuphukayo ivumela isiqu se-valve ukuba sikhuphuke phezulu naphansi ngokunyuka nokuwa kwesango ngesikhathi sokusebenza. Abasebenzisi bangabona isikhundla sesiqu se-valve bahlulele ngendlela enembile nangokunembile ngesimo sokuvula nokuvala se-valve, esiza ngokusebenza nsuku zonke kanye nabaphathi. Ngasikhathi sinye, isakhiwo esithambile sendawo sisebenzisa izinto ezithambile njenge-rubber ngokuqina okuhle njengezimpawu. Uma kuqhathaniswa nezimpawu zensimbi yendabuko, kungafinyelela umphumela wokuvalwa kwesikhashana, ukuvikela ngempumelelo ukuvuza okuphakathi, futhi uhlangane nezimo ezahlukahlukene zokusebenza ngezidingo eziqinile zokubekelwa uphawu.

Amapharamitha Ezobuchwepheshe

Ukufakwa nokulungiswa

Amaphuzu Wokufaka: Ngaphambi kokufaka, hlola ngokucophelela ukuthi ngabe imodeli nokucaciswa kwe-valve kuyahambisana nezidingo zokwakhiwa, gxila ukuthi iziqu ze-valve ziboshelwe futhi zikhubazekile, njll, futhi zihlanze imfucumfucu kanye ne-strit ngaphakathi kwe-valve. Ngesikhathi sokufakwa, qiniseka ukuthi i-valve ifakwa ngendlela efanele, futhi uphawu lokuqondisa lokugeleza emzimbeni we-valve kufanele lihambisane nokuholwa kwangempela kwe-medium. Lapho usebenzisa i-Flange uxhumano, khetha ama-gaskets afanelekile afanele, qinisa ama-bolts ngokulinganayo, bese uwaqinisa ngesinyathelo ngesinyathelo ngesinyathelo ngendlela yokulinganisa futhi unqamula ukuze uvikele ukuguqulwa kwe-flange noma ukubekwa uphawu okumpofu; Ukuxhumeka kwe-Welding kumele kusetshenziswe ochwepheshe ukuqinisekisa ikhwalithi ye-welding; Ukuxhumeka kwe-Clamp kumele kuqinisekise ukuthi i-valve ifanela kahle nge-pipeline flange. Ngaphezu kwalokho, i-valve kufanele ifakwe esimweni esilungele ukusebenza kanye nokunakekelwa, futhi indawo eyanele kufanele igcinwe ngokusebenza kwezandla, i-valve stem ukuphakamisa kanye nokuhlola nokulondolozwa kwansuku zonke kanye nokunakekelwa kwansuku zonke. Ngasikhathi sinye, gwema ukufaka i-valve ekugcizeleleni kwepayipi noma esimweni esithambekele ekudlidlizelweni.

Isondlo: Hlola njalo ukusebenza kokubekwa uphawu kwe-valve, ubone ukuthi ngabe kunezimpawu zokuvuza okuphakathi ngaphandle kwe-valve, futhi wahlulela isimo sokubopha uphawu ngokubheka izinguquko ekucindezelweni kwepayipi. Uma ukuvuza kutholakele, thola imbangela ngesikhathi. Kungase kube ukuguga noma ukulimala kwe-gasket yokubopha uphawu, ukugqoka nokudabula indawo yokubopha kwerabha yesango, ukungcola okunamathiselwe, noma ukwehluleka kwesakhiwo sokubopha phakathi kwesiqu se-valve kanye nesembozo se-valve. Ngokwezizathu ezahlukahlukene, faka esikhundleni se-gasket yokubopha ngokubopha, ukulungisa noma ukufaka indawo esikhundleni sesango, uhlanze imfucumfucu ebusweni bokubekwa uphawu, bese ulungisa noma ungene esikhundleni sesakhiwo sokubopha uphawu sehlulekile. Bheka ukuhamba kwesiqu se-valve njalo, hlola ukuthi i-torque yokusebenza iyinto ejwayelekile, noma ngabe i-valve stem ijikeleza kalula, nokuthi isango liyazungeza kalula, nokuthi isango liphakama futhi liphansi liphakeme. Uma i-valve stem ingashukumisi kalula, ingahle ibe khona ngenxa yokuthambisa okunganele, ukuguqulwa kwesiqu se-valve, noma ukungena kwemfucumfucu. Ungangeza ama-lubrice afanele, ulungile noma ungene esikhundleni sesiqu se-valve, futhi uhlanze imfucumfucu ngaphakathi kwe-valve. Ngasikhathi sinye, hlanza i-valve njalo ukuze ususe ukungcola komhlaba, uthuli kanye nokugqwala. Kuma-valves afakwe ezindaweni ezonakalisayo, kufanele kuthathwe izinyathelo ezingezekile zokulwa nokugqwala, njengokusebenzisa upende wokulwa nokulwa nokulwa nokulwa nokuwohloka, ukwelula impilo yensiza ye-valve. Ngaphezu kwalokho, ukuhlolwa okujwayelekile kanye nokunakekelwa kukagesi, ama-pneumatic, i-hydraulic namanye amadivaysi e-drive kufanele kwenziwe ukuqinisekisa ukulawula okunembile nokusebenza okuthembekile.
