I-Gate Valve Flanged End

Ingabe ukhona umehluko omkhulu phakathi koxhumano lwe-flanged kanye noxhumo lwe-screwed screwed kumavalvu esango?

Ukuxhuma okunamaphiko kusebenzisa ama-flange afanayo, amabhawodi nama-gaskets ukuxhuma amapayipi namavalvu. Zilingana namadayimitha amapayipi amakhulu kanye nemigqa yezimboni enengcindezi ephezulu. I-Disassembly yokulungisa ilula, futhi ukusebenza kokuvala kuhlala kuzinzile isikhathi eside.

Iziphetho ezinomucu zigoqa ngqo kumapayipi amancane ngaphandle kwama-flange. Abiza kancane futhi athatha indawo encane yokufaka, kodwa afanele usayizi omncane, imigqa yesevisi yokukhanya ephansi. Amajoyinti anemicu athambekele ekungeneni ngaphansi kwezinga lokushisa eliphezulu nezimo zokusebenza ezinzima, futhi ayakhohlisa ukuhlukana kamuva.

Izimfanelo Ezibalulekile

Ingabe kulungile ukusebenzisa ama-valve esango ane-flanged ukuze wehlise ijubane noma ulungise ukugeleza koketshezi?

Asincomi ukugeleza kwe-throttling ngama-valve esango ane-flanged nhlobo. Lawa ma-valve akhelwe ngokuqinile ukuze avuleke noma avale ngokugcwele.

Ukugcina i-wedge ivulekile uhhafu kuvumela i-medium egeleza ngokushesha ukuthi iqhubeke ibe nomthelela endaweni yokuvala, ezoklwebha futhi igqoke isihlalo ngokushesha, okuholela ekuvuzeni okungapheli. Ukuvuleka kancane kuphinde kubangele ukudlidliza okuqinile nesando samanzi esilimaza i-valve namapayipi axhunyiwe. Amavalvu eglobhu noma amabhola amabhola afaneleka kakhulu uma kudingeka ukulungiswa kokugeleza.

Imaphi amasayizi avamile amabanga nezilinganiso zokucindezela i-Gate Valve Flanged End evame ukungena kuyo?

Osayizi abajwayelekile bafaka i-DN50 kuya ku-DN1200. I-DN80, i-DN100, i-DN150, i-DN200 kanye ne-DN300 amasayizi ethu athengiswa kakhulu kumaphrojekthi ezimboni nomasipala.

Amazinga okucindezela ajwayelekile afaka amasistimu amabili ajwayelekile:

I-GB ejwayelekile PN10, PN16, PN25, PN40; I-ANSI Class 150, Class 300, Class 600.

I-PN16 kanye ne-Class 150 zisebenzela amanzi amaningi, isitimu kanye namapayipi amakhemikhali avamile, kuyilapho amazinga okucindezela aphezulu ephatha isitimu sezinga eliphezulu kanye nezimo zokusebenza ze-petrochemical.

Yiziphi izinto ezisetshenziswayo ezisetshenziswayo zokukhiqiza ama-valve esango ane-flanged?

Umzimba we-valve kanye nezinto ze-wedge zikhethwa ngokuya maphakathi nezinga lokushisa:

I-WCB carbon steel: ukukhetha kwethu okujwayelekile, amandla aqinile kawoyela ojwayelekile, amanzi kanye nesitimu esinezinga lokushisa eliphakathi nendawo

I-SS304 / SS316 insimbi engagqwali: i-anti-corrosion, ilungele uketshezi lwamakhemikhali namapayipi amanzi olwandle

I-Ductile iron: ukukhetha ukonga kwezinhlelo zamanzi ahlanzekile kamasipala anengcindezi ephansi

Izinsiza ezihlukene zokuvala ziphinde zifaniswe: ukupakishwa kwegraphite yesitimu esinokushisa okuphezulu, i-RPTFE yemidiya ebolayo ebuthaka, kanye ne-Stellite hard alloy yobuso obungagugeki bengcindezi ephezulu.

Yiziphi izinyathelo zokugcina nsuku zonke okufanele sizilandele ze-Gate Valves Flanged End?

Ukuhlola akuvamile kungenza i-valve yesango lakho ihlale isikhathi eside.

Qinisekisa ukuthi uyivula ngokugcwele noma uyivala ngokugcwele ivalvu kuphela, ungayishiyi ivuliwe phakathi ngoba lokhu kuzoguga isivalo ngokushesha.

Hlola amabhawodi e-flange njalo ezinyangeni ezimbalwa. Qinisa noma yiziphi ezixegayo bese ushintsha ama-gasket amadala uma ubona ukuvuza eduze kwelunga.

Faka okokugcoba okukhethekile esiqwini sevalvu njalo ukuze isibambo sijike kahle ngaphandle kokubambeka.

Sula uthuli nokunqwabelana kwamakhemikhali kuvalvu engaphandle ukuze umise ukugqwala emzimbeni nama-flange.

Uma i-valve isavuza lapho ivaleke ngokugcwele, yihlukanise ukuze uhlanze noma ushintshe amaweji asegugile nezihlalo zokuvala.

Uma i-valve ingeke isetshenziswe isikhashana, yishiye ivuleke ngokugcwele bese uvala isiqu ukuze usivikele ekugqwaleni nasekungcoleni.
