Ivalve yesango le-Hydraulic wedge DN400 PN25

1. Inkcazo kunye neMiba ePhambili

I-Hydraulic Wedge Gate Valve yivalve eshukumayo ehambelanayo apho idiskhi emile okwe wedge (isango) iphakanyiswe okanye ithotywe yi-actuator yehydraulic ukulawula ukuhamba kolwelo.

Iimpawu eziphambili zobukhulu kunye neklasi:

• Uyilo olupheleleyo lweBore: Idayamitha yangaphakathi ihambelana nombhobho (DN400), okukhokelela ekuhleni koxinzelelo oluphantsi xa ivuleke ngokupheleleyo kwaye ivumela ukuhagwa kwemibhobho.
• Ukuqukuqela okuBidirectional: Ilungele ukuhamba kuwo omabini amacala.
• Isiqu esinyukayo: Isiqu siyenyuka njengoko ivalve ivulwa, inika imbonakalo ecacileyo yendawo yevalvu.
• Ukutywinwa kwe-Metal-to-Metal: Ngokuqhelekileyo kusetyenziswa i-wedge kunye namakhonkco esihlalo anobuso obunzima (umzekelo, nge-Stellite) ukwenzela ukhukuliseko kunye nokungagugi.
• Ulwakhiwo oluqinileyo: Yenzelwe ukujongana noxinzelelo oluphezulu kunye nemikhosi, ekhokelela kumzimba onzima kunye nohlala ixesha elide, kaninzi ukusuka kwintsimbi okanye intsimbi.

2. Amacandelo aphambili

1. Umzimba: Esona sakhiwo sinoxinzelelo oluphambili, ngokuqhelekileyo lwenziwe kwiCarbon Steel (WCB) okanye iStainless Steel (CF8M/316SS). Iziphelo ezinamaphiko (umzekelo, i-PN25/ASME B16.5 Udidi lwe-150) zisemgangathweni we-DN400.
2. Ibhonethi: Ibolted emzimbeni, igcina isiqu kwaye ibonelela ngomda woxinzelelo. Ngokuqhelekileyo ibhonethi eyandisiweyo isetyenziselwa iinjongo zokugquma.
3. IWedge (Isango): Icandelo elingundoqo lokutywina. Kwi-PN25, i-Flexible Wedge ixhaphakile. Inomnqamlezo okanye i-groove ejikeleze i-perimeter yayo evumela ukuba i-wedge iguquke kancinci, iphucule ukutywinwa kunye nokuhlawulela utshintsho oluncinci ekulungelelaniseni isihlalo ngenxa yokwandiswa kwe-thermal okanye uxinzelelo lombhobho.
4. Isiqu: Ishafti enemisonto ephezulu (umzekelo, i-SS420 okanye i-17-4PH iStainless Steel) ehambisa amandla ukusuka kwi-actuator ukuya kwi wedge.
5. Izihlalo: Izangqa ezinobuso obunzima zicinezelwe okanye zidityaniswe emzimbeni apho i-wedge itywina khona. Badala ukuvalwa okuqinileyo.
6. Ukupakisha: Itywina (isoloko igraphite yobushushu obuphezulu) ejikeleze isiqu, equlethwe kwibhokisi yokupakisha, ukuthintela ukuvuza kokusingqongileyo.
7. I-Hydraulic Actuator: Isimbo sepiston okanye i-yoke ye-scotch actuator eqhutywa luxinzelelo lwehydraulic (ngokuqhelekileyo ioli). Inika i-torque ephezulu / i-thrust efunekayo ukusebenzisa i-valve enkulu ye-DN400 ngokuchasene noxinzelelo oluphezulu oluphezulu.

3. UmGaqo wokuSebenza

• Ukuvulwa: Ulwelo lwe-hydraulic lufakwe kwi-actuator, luhambisa ipiston. Le ntshukumo iguqulwa ibe yi-rotary (idyokhwe ye-scotch) okanye i-linear (i-piston ene-linear) intshukumo ejikeleza isiqu sevalve. Isiqu singena kwi wedge, siyiphakamisela ngokupheleleyo kwibhonethi, singathinteli indlela yokuhamba.
• Ukuvala: I-hydraulic fluid ifakwe kwelinye icala le-actuator, ibuyisela umva intshukumo. Isiqu sijikeleza kwaye sityhala i-wedge phantsi kwindawo evaliweyo, apho icinezelwe ngokuqinileyo kumakhonkco ezihlalo ezimbini, idala itywina.

Inqaku elibalulekileyo: Le valve yenzelwe ukuba yodwa (ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo). Akufanele isetyenziselwe ukunyathela okanye ukulawula ukuhamba, njengoko oku kuya kubangela ukungcangcazela, i-cavitation, kunye nokukhukuliseka ngokukhawuleza kwe-wedge kunye nezihlalo.

4. Usetyenziso oluqhelekileyo

Ngenxa yobungakanani bayo kunye noxinzelelo loxinzelelo, le valve isetyenziswa ekufuneni izicelo zamashishini:

• UThutho lwaManzi kunye noSasazo lwaManzi: Ukwahlula amacandelo emibhobho emikhulu.
• Izityalo zamandla: Iinkqubo zamanzi zokupholisa, iintambo zamanzi okutya.
• Amanzi eNkqubo yoShishino: Izityalo zemizi-mveliso emikhulu.
• Izityalo ze-Desalination: I-High-pressure reverse osmosis (RO) imigca.
• Ukwenziwa kweMigodi kunye neziMbiwa: Imibhobho eludaka (enokukhethwa kwezinto ezifanelekileyo).

5. Izinto eziluncedo nezingeloncedo

6. Iingqwalasela ezibalulekileyo zokuKhetha nokuSetyenziswa

• Ukukhethwa kwezinto: Tshatisa umzimba / i-wedge / isihlalo (WCB, WC6, CF8M, njl.) kwinkonzo yolwelo (amanzi, ukubola, ubushushu).
• Qeda uQhagamshelwano: Qinisekisa imigangatho yeflange kunye nokujongana (RF, RTJ) kuhambelana nombhobho.
• I-Hydraulic Power Unit (HPU): I-valve idinga i-HPU eyahlukileyo ukuvelisa uxinzelelo lwe-hydraulic. Qwalasela isantya sokusebenza esifunekayo, uxinzelelo, kunye nolawulo (kwindawo/ekude).
• Imo Yokungaphumeleli: I-actuator inokuchazwa njenge-Fail-Open (FO), i-Fail-Closed (FC), okanye i-Fail-in-Last-Position (FL) ngokuxhomekeke kwiimfuno zokhuseleko.
• IValve yokudlula: Kwizicelo zoxinzelelo oluphezulu, ivalve encinci yokudlula (umzekelo, i-DN50) isoloko ifakelwe ukulinganisa uxinzelelo kwi-wedge ngaphambi kokuvula ivalve ephambili, ukunciphisa i-torque efunekayo yokusebenza.

Isishwankathelo, i-Hydraulic Wedge Gate Valve DN400 PN25 yintsebenzo ephezulu, i-heavy-duty workhorse yokumisa ngokupheleleyo okanye ukuqala ukuhamba kwamanzi kwimibhobho emikhulu, ephezulu. Ukusebenza kwayo kwe-hydraulic kwenza ukuba ilungele iindawo ezikude okanye ezizenzekelayo zokuzihlukanisa ezibalulekileyo.
