Sikwamkele iiodolo ze-OEM kunye ne-ODM, kunye nobungakanani obuncinci bokuodola. Iimveliso zethu ezithembekileyo zithunyelwa kumazwe angaphandle kwaye ziphumelela ukuqondwa ngokubanzi kubathengi.

Yintoni ivalve yebhola ezinzileyo yetrunnion?

Iivalvu zebhola ezizinzileyo zeTrunnion zenzelwe uxinzelelo oluphezulu kunye nemibhobho emikhulu edayamitha. Xa kuthelekiswa neevalvu zebhola ezidadayo, ibhola itshixiwe endaweni yayo ngokusebenzisa isiqu sevalvu ephezulu kunye ne-trunnion shaft esezantsi. Ijikeleza nje ukuvula nokuvala ngaphandle kokukhukuliseka xa uxinzelelo lusebenza. Ulwakhiwo lwe-trunnion luthatha uninzi loxinzelelo loxinzelelo lwe-fluid, luthoba ngokufanelekileyo ingxabano kwisitulo sokutywina. Olu luyilo lwenza iivalvu zebhola ezizinzileyo zizinze ngakumbi kwaye zomelele kushishino oluqhubekayo lwexesha elide.

Yintoni umahluko phakathi kwevalve yebhola esisigxina kunye nevalve yebhola edadayo?

Lo ngowona mbuzo ubuzwa rhoqo ngabathengi behlabathi. Umahluko ongundoqo ulele kwisakhiwo esixhasayo sebhola kunye nemo yoxinzelelo.

Iivalvu zebhola ezidadayo azinankxaso yetrunnion esezantsi. Xa uxinzelelo lwemibhobho lunyuka, isiphakathi sityhala ibhola ngokuqinileyo kwisitulo esisezantsi. Oku kudala ukungqubana okukhulu, itorque ephezulu yokusebenza kunye nokunxiba kwezitulo ezikhawulezayo. Iintlobo ezidadayo zilungele kuphela ubungakanani obuncinci kunye neemeko zokusebenza eziphantsi ukuya koxinzelelo oluphakathi.

Iivalvu zebhola zetrunnion ezizinzileyo zilungisa ibhola kwindawo yayo. Umthwalo woxinzelelo wenziwa yi-trunnion shaft kunye nokuthwala umzimba, kungekhona isihlalo sokutywina. Ibonisa i-torque ephantsi yokusebenza, i-abrasion yesihlalo esincinci, ukusebenza kokutywinwa okuzinzileyo kunye nobomi benkonzo obude. Kwi-DN100 / NPS4 nangaphezulu kwemibhobho emikhulu okanye yoxinzelelo oluphezulu, iivalve zebhola ezisisigxina zihlala zikhethwa kuqala kubunjineli bezoshishino.

Iimpawu eziphambili

Zisetyenziswa phi iivalvu zebhola ezisisigxina?

Iivalvu zebhola ezisisigxina ze-Trunnion zisetyenziswa ngokubanzi kwiimeko zoshishino ezinzima ezifuna ukutywinwa okuzinzileyo kunye nobomi obude benkonzo. Amashishini aqhelekileyo aquka imibhobho yothumelo lwe-oyile nerhasi, iiplanti zepetrochemical, izikhululo zamandla ashushu, iiprojekthi zokucocwa kwamanzi, izikhululo zerhasi yendalo kunye neenkqubo zokuhanjiswa kolwelo olude kwimizi-mveliso. Ilungele ngokukodwa iimeko zokusebenza ezinoxinzelelo oluphezulu, izinga lokuhamba okukhulu, ukutshintsha rhoqo kunye neemfuno ezingqongqo zokuvuza kwe-zero.

Zeziphi izixhobo ozixhasayo kwimizimba yevalve yebhola esisigxina kunye namalungu angaphakathi?

Sinikezela ngoluhlu lwezixhobo zomzimba kunye nezangaphakathi ukufanisa iimeko ezahlukeneyo zokusebenza. I-WCB carbon steel lukhetho lwethu oluqhelekileyo lwemibhobho yezoshishino ngokubanzi, ukuhambisa ukuqina okuthembekileyo kwixabiso elikhuphisanayo. Kwiinkonzo ezinolwelo oludlekayo okanye igesi, sikhetha i-CF8 (304) kunye ne-CF8M (316) yensimbi engenasici yokumelana ne-corrosion ethembekileyo.

Kwakhona siyakwazi ukufumana izinto ezikhethekileyo ezifana nentsimbi ephantsi yobushushu kunye nentsimbi ye-alloy kwiiprojekthi ezinzima, ezifunayo. Kwiindawo zangaphakathi ezifana nebhola kunye nezihlalo zevalve, siyakwazi ukuqwalasela imidibaniso eyahlukeneyo ngokusekelwe kwiimfuno zakho zokusebenza.

Yeyiphi imigangatho kunye neziqinisekiso iivalvu zakho zebhola ezizinzileyo zithobelayo?

Zonke iivalvu zethu zebhola ezimiselweyo ze-trunnion zenziwe ngokungqongqo ngokwe-API 6D kunye ne-ASME B16.34 imigangatho yamazwe ngamazwe. Ifektri yethu ine-API epheleleyo, i-ISO kunye ne-CE izitifiketi. Yonke ivalve egqityiweyo idlula uvavanyo loxinzelelo lweqokobhe lobuchwephesha, uvavanyo lokuqina kwesitulo kunye novavanyo lokuqina lomoya phambi kokuziswa. Zonke iingxelo zovavanyo kunye namaxwebhu esatifikethi anokunikezelwa ukuxhasa ukuhlolwa kweprojekthi yabathengi kunye nokukhutshwa kwezithethe.

Ngaba ndingakhetha itywina elithambileyo okanye ivalve yentsimbi esisigxina yebhola?

Kuxhomekeke kumbhobho ophakathi kunye nobushushu bokusebenza. Izivalo zebhola ezihleliyo ezithambileyo zamkela i-PTFE okanye i-RPTFE yokutywina, iphumeza ukuvuza kweqamza elingagungqiyo elinguziro. Zilungele amanzi acocekileyo, igesi kunye nobushushu obuqhelekileyo be-oyile obuphakathi kunye neemfuno ezingqongqo zokutywinwa.

Iivalvu zebhola eziqinileyo ezitywiniweyo eziqinileyo ziyakwazi ukuziqhelanisa nobushushu obuphezulu, uxinzelelo oluphezulu kunye nephakathi eliqulathe amasuntswana aqinileyo. Isakhiwo sokutywinwa kwesinyithi ukuya kwintsimbi sinxiba-i-resistant-resistant and high-temperature resistant, sisetyenziswa ngokubanzi kwiimeko ezinzima zepetrochemical kunye ne-high-temperature pipeline.

Ngaba iivalvu zebhola ezisisigxina zinokuxhotyiswa ngee-actuator zombane okanye zepneumatic?

Ewe, inokwenzeka ngokupheleleyo. Iivalve zethu zebhola ezisisigxina zinokudityaniswa nokusebenza kwegiya yezandla, i-pneumatic actuators, i-actuator yombane kunye ne-hydraulic actuators. Ngombulelo kwisakhiwo senkxaso ye-trunnion, i-torque yokusebenza iphantsi kakhulu kuneevalve zebhola ezidadayo. Inokunciphisa ngokufanelekileyo iindleko zokumisela i-activators kwaye iqinisekise ukuvulwa okuzenzekelayo kunye nokusebenza kokuvala.

Sithini isiqinisekiso sakho somgangatho kunye nepolisi emva kokuthengisa?

Zonke iivalvu zethu zebhola ezixhonywe kwitrunnion ezisisigxina zonwabela iwaranti esemgangathweni yexesha elide. Sinikezela ngenkxaso epheleleyo yobugcisa, isikhokelo sofakelo kunye nokubonisana emva kokuthengisa. Sigxila kubudlelwane bentsebenziswano yexesha elide kunye nabathengi behlabathi, hayi izivumelwano zexesha elinye.
