ISango iValve Flanged End

Ngaba kukho nawuphi na umahluko omkhulu phakathi koqhagamshelo olunamaphiko kunye noqhagamshelo oluphothiweyo oluphothiweyo kwiivalvu zesango?

Ukudityaniswa kwe-flanged kusebenzisa iiflange ezihambelanayo, iibholiti kunye ne-gaskets ukudibanisa imibhobho kunye neevalvu. Zifanele iidayimitha ezinkulu zepayipi kunye nemigca yoshishino ephezulu yoxinzelelo. I-Disassembly yokulungisa ilula, kwaye ukusebenza kokutywinwa kuhlala kuzinzile ixesha elide.

Iziphelo ezinemisonto zijija ngqo kwimibhobho emincinci ngaphandle kweeflange. Babiza ngaphantsi kwaye bathatha indawo yokufakela encinci, kodwa bafanele kuphela ubungakanani obuncinci, imigca yenkonzo yokukhanya ephantsi. Amalungu anemisonto athambekele ekungeneni phantsi kobushushu obuphezulu kunye neemeko ezinzima zokusebenza, kwaye kuyakhohlisa ukuhlukana kamva.

Iimpawu eziphambili

Ngaba kulungile ukusebenzisa iivalvu zesango ezinamaphiko ukucothisa okanye ukulungelelanisa ukuhamba kwamanzi?

Asikukhuthazi ukuhamba kwe-throttling kunye neevalvu zesango ezinqamlekileyo. Ezi zivalo ziyilelwe ngokungqongqo ukuba zivule okanye zivaliwe ngokupheleleyo.

Ukugcina i-wedge ivulekile ngesiqingatha kuvumela i-medium ebaleka ngokukhawuleza ibe nefuthe ngokuqhubekayo kwindawo yokutywina, eya kukrwempa kwaye inxibe isitulo ngokukhawuleza, okukhokelela ekuvuzeni okusisigxina. Ukuvuleka okungaphelelanga nako kubangela ukungcangcazela okunamandla kunye nehamile yamanzi eyonakalisa ivalve kunye nemibhobho edityanisiweyo. Iivalvu zeglobhu okanye iivalvu zebhola zifaneleke ngakumbi ukuba kufuneka uhlengahlengiso lokuhamba.

Zeziphi iindidi zobungakanani obuqhelekileyo kunye noxinzelelo lwe-Gate Valve Flanged End ehlala ingena?

Ubungakanani obuqhelekileyo obuqhelekileyo bugubungela i-DN50 ukuya kwi-DN1200. I-DN80, i-DN100, i-DN150, i-DN200 kunye ne-DN300 ziisayizi zethu ezithengiswa kakhulu kwiiprojekthi zoshishino kunye nomasipala.

Amanqanaba oxinzelelo oluqhelekileyo abandakanya iinkqubo ezimbini eziphambili:

umgangatho we-GB PN10, PN16, PN25, PN40; I-ANSI Class 150, iKlasi ye-300, i-Class 600.

I-PN16 kunye neKlasi ye-150 isebenza kuninzi lwamanzi, umphunga kunye nemibhobho yeekhemikhali eziqhelekileyo, ngelixa amanqanaba aphezulu oxinzelelo aphethe i-steam-temp and petrochemical working cenarios.

Yeyiphi imathiriyeli ekrwada eqhelekileyo eyamkelwayo ukwenza iivalvu zesango ezinamaphiko?

Umzimba wevalufa kunye nezixhobo ze-wedge zikhethwa ngokuphakathi kunye nobushushu:

I-WCB carbon steel: ukhetho lwethu oluqhelekileyo, amandla aqinileyo kwioli eqhelekileyo, amanzi kunye nobushushu obuphakathi

I-SS304 / SS316 intsimbi engatyiwayo: i-anti-corrosion, ilungele ulwelo lwekhemikhali kunye nemibhobho yamanzi olwandle

I-Ductile iron: ukukhethwa kwezoqoqosho kwiinkqubo zamanzi acocekileyo zikamasipala ezinoxinzelelo oluphantsi

Izixhobo zokutywina ezahlukeneyo zikwadityaniswa: ukupakishwa kwegraphite kubushushu obuphezulu, i-RPTFE yemithombo yeendaba ezonakalisayo ebuthathaka, kunye ne-Stellite hard alloy yobuso obunganyangekiyo bokutywinwa koxinzelelo oluphezulu.

Ngawaphi amanyathelo okugcina imihla ngemihla ekufuneka siyilandele kwiSango iValves Flanged End?

Ukwenza iitshekhi ezilula rhoqo kunokwenza ivalve yesango lakho ihlale ixesha elide.

Qinisekisa ukuba uyivula ngokupheleleyo okanye uyivale ngokupheleleyo ivalve, ungayishiyi ivuleke phakathi njengoko oku kuya kuphelelwa isitywina ngokukhawuleza.

Jonga iibholithi zeflange qho kwiinyanga ezimbalwa. Qinisa naziphi na ezikhululekileyo kwaye ubuyisele iigaskets ezindala ukuba ubona ukuvuza kwindawo edibeneyo.

Beka isithambiso esikhethekileyo kwisiqu sevalve ngoku kwaye ngoko ke isiphatho sijike kakuhle ngaphandle kokuxinga.

Sula uthuli kunye nokwakheka kweekhemikhali kwivalve ngaphandle ukunqanda ukuvela komhlwa emzimbeni kunye neeflange.

Ukuba ivalve isavuza xa ivalwe ngokupheleleyo, yihlukanise ukuze ucoce okanye utshintshe iiweji ezigugileyo kunye nezihlalo zokutywina.

Ukuba ivalve ayiyi kusetyenziswa ixeshana, yiyeke ivuleke ngokupheleleyo kwaye ugqume isiqu ukuze usikhusele kumhlwa nokungcola.
