I-Valve Yesango Elingangeni Ukugqwala

Siyimboni yendawo yamavalvu enezitifiketi ezigcwele ze-ISO, CE kanye ne-API. Sibheka zonke izinto ze-alloy ezingenayo futhi sihlola ukusebenza kokuvala kwe-valve eqediwe kahle ngaphambi kokuthunyelwa. Sivulekele ukulungiswa kwe-OEM ne-ODM kuma-valve alloys neziphetho ze-flange, ngaphandle kwemikhawulo eqinile ye-oda. Amavalvu ethu amasango amelana nokugqwala adayisela amazwe amaningi, futhi abathengi bezitshalo zamakhemikhali balokhu bebuya ukuze baphinde ba-oda.

Imaphi ama-alloys omzimba we-valve asebenza kangcono lapho uphatha imidiya yenqubo ebola kakhulu?

Sihlinzeka ngohlu olugcwele lwama-alloys amelana nokugqwala aklanyelwe uketshezi lwamakhemikhali ahlukene ukuze sandise isikhathi sokusebenza kwamavalvu. I-CF8, CF8M kanye ne-CF3M yensimbi engagqwali ihambisana ne-asidi ethambile, i-alkali ebuthakathaka namanzi anamazinga aphansi e-chloride. I-alloy 20 isebenza kahle kakhulu kumapayipi aphethe i-nitric exubile ne-sulfuric acid, amelana nokugqwala okufanayo ngaphansi kwezimo zamakhemikhali eziyinkimbinkimbi. Impahla ye-Titanium iyikhethelo eliphezulu lamanzi olwandle, i-brine egxilile kanye nemidiya equkethe i-chlorine egoba kalula insimbi engagqwali evamile. Ezindaweni zokuvala, wonke amaweji nezihlalo zamavalvu zimbozwa nge-Stellite noma i-Alloy C ingxubevange eqinile ukuze ime endaweni yokuwasha ephakathi nendawo ebolayo.

Izimfanelo Ezibalulekile

Yiziphi izinyathelo ezisebenzayo engingazithatha ukuze nginciphise umonakalo wokugqwala futhi nginwebe impilo yesevisi yama-valve esango?

Okokuqala, khetha i-alloy yomzimba ehambisanayo ngokuya ngendawo yakho ethile, izinga lokushisa kanye nokugxila; amavalvu ensimbi ye-carbon steel azogqwala ngokushesha endaweni ene-acidic noma emanzini anosawoti. Okwesibili, khetha izingxenye zangaphakathi eziqinile ezigcwele ingxubevange esikhundleni se-carbon steel wedges, njengoba indawo yokuvala inamandla aphakathi nendawo. Okwesithathu, faka i-PTFE gaskets yemvilophu phakathi kwama-flange ukuze uhlukanise uketshezi olubolayo ebusweni bensimbi futhi ugweme ukugqwala kwemifantu. Okwesine, ungashiyi i-valve icwiliswe kancane oketshezini olubolayo olungalungiswanga isikhathi eside sokungenzi lutho. Okwesihlanu, kumavalvu afakwe ngaphandle noma phesheya kwezilwandle, hlola indawo ejwayelekile kanye nokugcinwa kwezingubo zokuzivikela njalo.

Ngingamtholaphi umkhiqizi ozinzile, ochwepheshile ohlinzeka ngamavalvu esango amelana nokugqwala?

Iqembu le-Huadu Valve elizinze e-Wenzhou, e-China, lingumkhiqizi wakho othembekile oqondile wamavalvu esango elilwa nokugqwala. Siphethe izitifiketi eziphelele zokukhiqiza ze-ISO, CE kanye ne-API. Sishintsha ama-valve ukuze afanele ukusethwa kwamapayipi akho, kusukela ekushintsheni ama-alloys alwa nokugqwala kuya ekushintsheni izinhlobo ze-flange kanye nokuqeda ukuxhumana. Sithatha ama-oda amancane esivivinyo kanye nama-oda ephrojekthi amaningi we-OEM/ODM ngokufanayo. Ivalvu ngayinye ithola ukuhlaziywa kwezinto kanye nokuhlolwa okuqinile kokuvuza kwengcindezi ngaphambi kokuba ipakishwe futhi ithunyelwe phesheya.

Ngingakwazi ukusebenzisa le valve yesango elivimbela ukugqwala ukulawula ukugeleza noma ukulungisa umfutho wepayipi?

Le valve yesango yenzelwe kuphela ukuvula noma ukuvala ngokugcwele amapayipi. Angeke isetshenziselwe ukunqanda ukugeleza noma ukunciphisa ukucindezela. Uma ugcina ivalvu ivulekile kancane, i-corroal medium egeleza ngokushesha izolokhu ikhuculula amaweji ensimbi aqinile, okubangele ukuhuzuka okungenakulungiseka kwendawo kanye nokuvuza okuqhubekayo kwangaphakathi. Uma udinga ukugeleza okunembile noma ukulawula ingcindezi, ama-valve okulawula azimele kufanele afakwe ngokuhlukana.

Iziphi izinkambu zezimboni ezamukela kabanzi ama-valve esango amelana nokugqwala kumapayipi azo okukhiqiza?

Lawa mavalvu esango elilwa nokugqwala ayisisetshenziswa esibalulekile sezimboni eziningi ezinobunzima. Asetshenziswa kakhulu ezimbonini zokucubungula amakhemikhali ezinemigqa yokudiliva ene-asidi ne-alkali, iziteshi zokususa usawoti emanzini olwandle, amasistimu okubuyisela amanzi angcolile, izindawo zokuhlanza amanzi angcolile ezimbonini, amaphrojekthi olwandle asogwini olungasogwini, kanye nemihlangano yokucobelelana ngolwazi yokukhiqiza imithi ethutha izinto zamakhemikhali ezingavuthiwe ezicebile nge-chloride futhi ezonakalisayo.
