1. Umklamo Wezihlalo Ezikhethekile

I-valve yebhola entantayo isebenzisa ukwakheka kwesakhiwo sendandatho yesivalo esiguquguqukayo. Uma ingcindezi ephakathi iphansi, indawo yokuxhumana yendandatho yesivalo nebhola incane. Ngakho-ke kwakheka isilinganiso sokuvala esiphezulu endaweni lapho indandatho yesivalo nebhola lixhumana khona ukuqinisekisa ukuvalwa okuthembekile. Uma ingcindezi ephakathi iphakeme, indawo yokuxhumana yesivalo nebhola iba nkulu kanye nokuguquguquka kwendandatho yesivalo, ukuze indandatho yesivalo ikwazi ukubekezelela ukucindezelwa okuphezulu okuphakathi ngaphandle kokulimala.

2. Umklamo Wesakhiwo Ongashiswa Ngumlilo

Uma kwenzeka umlilo ngesikhathi kusetshenziswa ivalvu, indandatho yesihlalo eyenziwe nge-PTFE noma ezinye izinto ezingezona ezensimbi izobola noma yonakale ngaphansi kokushisa okuphezulu futhi ibangele ukuvuza okuphezulu. Indandatho yokuvala engashisi umlilo ibekwe phakathi kwebhola nesihlalo ukuze ngemva kokuba isihlalo sevalvu sishisiwe, i-medium izosunduza ibhola ngokushesha iye endandatho yokuvala yensimbi engezansi ukuze yakhe isakhiwo sokuvala insimbi esisekelayo kuya kwensimbi, esingalawula ngempumelelo ukuvuza kwevalvu. Ngaphezu kwalokho, i-gasket yokuvala i-flange ephakathi yenziwe nge-gasket yensimbi enesilonda, engaqinisekisa ukuvalwa ngisho nangaphansi kokushisa okuphezulu. Umklamo wesakhiwo esingashisi umlilo se-floating ball valve uhambisana nezidingo ku-API 607, spi 6FA, BS 6755 kanye nezinye izindinganiso.

3. Ukuvalwa Okuthembekile Kwesiqu Sevalvu

Isiqu sinikezwa ihlombe phansi ukuze lingaphumi yi-medium ngisho nangaphansi kwezimo ezimbi kakhulu njengokunyuka kwengcindezi okungavamile ngaphakathi kwe-valve cavity, ukwehluleka kwe-gland plate njll. Ngaphezu kwalokho, ukuze kugwenywe ukuvuza ngemva kokushiswa kwesiqu uma kwenzeka umlilo, i-thrust bearing ibekwa endaweni lapho i-stem shoulder kanye nomzimba oxhumana khona ukuze kwakheke isihlalo sokuvala esingemuva. Amandla okuvala e-reverse seal azokwanda ngokuya ngokwanda kwengcindezi ephakathi, ukuze kuqinisekiswe ukuvalwa kwesiqu okuthembekile ngaphansi kwengcindezi ehlukahlukene, kuvinjelwe ukuvuza futhi kugwenywe ukusabalala kwengozi.

Isiqu samukela isakhiwo sokuvala ukupakisha sohlobo lwe-V. Ukupakisha kohlobo lwe-V kungashintsha ngempumelelo amandla okucindezela kanye namandla aphakathi e-gland abe amandla okuvala esiqu.

Ngokwezidingo zomsebenzisi, indlela yokucindezela ukupakisha okulayishwe ngentwasahlobo yediski ingasetshenziswa ukwenza ukuvalwa kokupakisha kwesiqu kuthembeke kakhudlwana.

4. Isakhiwo Esilwa Nokuma

I-valve yebhola inikezwe isakhiwo esilwa nokuma futhi isebenzisa idivayisi yokukhipha ugesi ongaguquki ukuze yakhe ngqo isiteshi esingaguquki phakathi kwebhola nomzimba noma yakhe isiteshi esingaguquki phakathi kwebhola nomzimba ngesiqu, ukuze ikhiphe ugesi ongaguquki okhiqizwa ngenxa yokungqubuzana ngesikhathi sokuvulwa nokuvalwa kwebhola nesihlalo ngepayipi, igweme umlilo noma ukuqhuma okungase kubangelwe yinhlansi engaguquki nokuqinisekisa ukuphepha kohlelo.

5. Ukuvimbela Ukukhiya Nokungasebenzi Kahle

I-valve yebhola yesandla ingakhiywa nge-lock uma ivuliwe ngokuphelele noma ivaliwe ngokuphelele. Ingxenye yokubeka evulekile nevaliwe engu-90° enembobo yokukhiya yenzelwe ukugwema ukusebenza kabi kwe-valve okubangelwa ukusebenza kwesibambo ngabangebona abaqhubi, futhi ingavimbela nokuvulwa noma ukuvalwa kwe-valve, noma ezinye izingozi ezibangelwa ukudlidliza kwephayiphi noma izinto ezingalindelekile. Isebenza kahle kakhulu ikakhulukazi ezintweni ezivuthayo. Isebenza kahle kakhulu ikakhulukazi kumafutha avuthayo naqhumayo, amapayipi amakhemikhali kanye nezokwelapha noma amapayipi asensimini. Ingxenye esekhanda lesiqu efakwe ne-handle isebenzisa umklamo oyisicaba. Lapho i-valve ivulwa, isibambo sihambisana nephayiphi, ukuze izinkomba zokuvula nokuvala ze-valve ziqinisekiswe ukuthi azinaphutha.

Izinto Zokwenziwa Kwe-Newsway Valve Imikhiqizo Yomkhiqizi

IUmkhiqizi weValve waseShayinakusukelaIShayina, umzimba wamavalvu ayo kanye nezinto zokuhlobisa zingatholakala ngaphakathiOkuhlanganisiweuhlobo kanyeUkulingisauhlobo. Eceleni kweInsimbi engagqwalifuthiInsimbi Yekhabhoniizinto ezibonakalayo, nathiama-valve okukhiqizaezintweni ezikhethekile ezifana ne-titanium, i-nickel alloys, i-HASTELLOY®*, i-INCOLOY®, i-MONEL®, i-Alloy 20, i-super-duplex, i-alloys engagqwali kanye nezinto ze-urea grade.
