I-Stainless Steel Pneumatic Actuator Flanged Floating Ball Valve China ifektri
Iyini i-valve yebhola entantayo ye-Pneumatic?
II-valve yebhola elintantayo lomoyasebenzisa ingcindezi yemvelo yomugqa ukuze ucindezele futhi uvale ibhola esihlalweni esingezansi komfula. Ingcindezi yomugqa ivezwa endaweni engaphezulu kakhulu - ubuso bonke obuphezulu bebhola, okuyindawo elingana nosayizi wangempela wepayipi.
A I-valve yebhola elintantayo lomoyaUma i-valve inebhola layo elintantayo (elingaqiniswanga yi-trunnion) ngaphakathi komzimba we-valve, iyashelela iye ohlangothini olungezansi bese icindezela ngokuqinile esihlalweni ngaphansi kwengcindezi ephakathi ukuqinisekisa ukuthembeka kokuvala. I-valve yebhola elintantayo inesakhiwo esilula, ukusebenza kahle kokuvala kodwa izinto zesihlalo ziyadingeka ukuze zimelane nomthwalo womsebenzi njengoba ingcindezi yokuvala ivuliwe yindandatho yesihlalo. Ngenxa yokungatholakali kwezinto zesihlalo ezisebenza kahle kakhulu, i-valve yebhola elintantayo isetshenziswa kakhulu ekusetshenzisweni kwengcindezi ephakathi noma ephansi.

isihlalo esintantayo ngaphansi kwengcindezi ephansi
isihlalo esintantayo ngaphansi kokucindezeleka okuphezulu
1. Umklamo Wezihlalo Ezikhethekile
samukela umklamo wesakhiwo sendandatho yokuvala eguquguqukayo yevalvu yebhola elintantayo. Uma ingcindezi ephakathi iphansi, indawo yokuxhumana yendandatho yokuvala nebhola incane. Kuzonciphisa ukungqubuzana kanye ne-torque yokusebenza futhi kuqinisekise ukuqina ngesikhathi esifanayo. Lapho ingcindezi ephakathi ikhuliswa, indawo yokuxhumana yendandatho yokuvala nebhola iba nkulu kanye nokuguquguquka kwendandatho yokuvala, ukuze indandatho yokuvala ikwazi ukubekezelela umthelela ophakathi ophezulu ngaphandle kokulimala.
2. Umklamo Wesakhiwo Ongashiswa Ngumlilo
Uma kwenzeka umlilo ngesikhathi kusetshenziswa i-valve, indandatho yesihlalo eyenziwe nge-PTFE noma ezinye izinto ezingezona ezensimbi izobola noma yonakale ngaphansi kokushisa okuphezulu futhi kuzoholela ekuvuza okukhulu koketshezi, kuyingozi kakhulu endaweni evuthayo noma eqhumayo. Indandatho yokuvala engashisi umlilo ibekwe phakathi kwebhola nesihlalo ukuze ngemva kokuba isihlalo se-valve sishisiwe, indawo yokuvala izosunduza ibhola ngokushesha iye endandatho yokuvala yensimbi engezansi ukuze yakhe isakhiwo sokuvala insimbi esisekelayo kuya kwensimbi esingalawula ngempumelelo ukuvuza kwe-valve. Ngaphezu kwalokho, i-gasket yokuvala i-flange ephakathi, engaqinisekisa ukuvalwa ngisho nangaphansi kokushisa okuphezulu. Umklamo wesakhiwo esingashisi umlilo se-floating ball valve uhambisana nezidingo ku-APl607, APl6FA, BS 6755 kanye nezinye izindinganiso.

4. Ukuvalwa Okuthembekile Kwesiqu Sevalvu
Isiqu senzelwe ihlombe phansi ukuze lingaphumi yi-medium ngisho nangaphansi kwesimo esibi kakhulu njengokunyuka kwengcindezi okungavamile ngaphakathi kwe-valve cavity, ukwehluleka kwe-gland plate nokunye. Ngaphezu kwalokho, ukuze kugwenywe ukuvuza ngemva kokushiswa kwesiqu uma kwenzeka umlilo, i-thrust bearing ibekwa endaweni lapho i-stem stem shoulder kanye nomzimba zithintana khona ukuze kwakheke isihlalo sokuvala esingemuva. Amandla okuvala e-reverse seal azokhula ngokuya ngokwanda kwengcindezi ephakathi, ukuze kuqinisekiswe ukuvalwa kwesiqu okuthembekile ngaphansi kwengcindezi ehlukahlukene, kuvinjelwe ukuvuza futhi kugweme ukusabalala kwengozi. Isakhiwo sokuvala i-V type packing senzelwe isiqu, i-V type packing ingashintsha ngempumelelo amandla okucindezela kanye namandla aphakathi e-gland abe amandla okuvala esiqu. Ngokwezidingo zabasebenzisi, indlela yokucindezela i-disc spring packing elayishwe nge-disc ingasetshenziswa ukwenza ukuvalwa kwe-stem packing kuthembeke kakhudlwana.

5. Ukuvimbela Ukukhiya Nokungasebenzi Kahle
I-valve yebhola yesandla ingakhiywa nge-lock endaweni evulekile noma evalwe ngokuphelele. Ingcezu yokubeka indawo evulekile nevalwe engu-90° enembobo yokukhiya yenzelwe ukugwema ukusebenza kabi kwe-valve okubangelwa ama-opreator angagunyaziwe, futhi ingavimbela nokuvulwa noma ukuvalwa kwe-valve, noma ezinye izingozi ezibangelwa ukudlidliza kwephayiphi noma izinto ezingalindelekile. Isebenza kahle kakhulu ikakhulukazi kumapayipi kawoyela avuthayo naqhumayo, amakhemikhali kanye nokusebenza kwezokwelapha noma amapayipi asensimini. Ingxenye esekhanda lesiqu efakwe ne-handle isebenzisa umklamo oyisicaba. Lapho i-valve ivulwa khona, i-handle ihambisana nephayiphi, futhi izinkomba zokuvala ze-valve ziqinisekisiwe ukuthi zilungile.
