2022-08-17
Kusiyanitsa pakati pa chisindikizo chofewa ndi chosindikizira cholimba cha valavu Kuphatikiza pa valavu yosagwirana ndi dzimbiri, valve yosindikizira yofewa imatanthawuza spool kapena mpando wa chimodzi mwa zinthu ziwiri zomwe sizinali zitsulo (makamaka PTFE, rabara, etc.) mawonekedwe osindikizidwa wa valavu. Kusindikiza kwa valavu yosindikizira ndikwabwinoko, koma pakuyika mapaipi, kuyeretsa dongosolo kumatha kusiya zinyalala zochulukirapo (monga kuwotcherera, zosefera zachitsulo, ndi zina zotero), zimadutsa mu valve yowongolera, zosavuta kukanda zofewa. chisindikizo mpando kapena spool, kotero kuti kutayikira kuchuluka kuchuluka, kudalirika kwa chisindikizo ndi osauka. Choncho, kusankha zofewa chisindikizo dongosolo ayenera kuganizira sing'anga kuyeretsa ndi okhwima payipi payipi pamaso ntchito. Chisindikizo chofewa cha valve ndi kusiyana kwa chisindikizo cholimba: (1) Chisindikizo chofewa Kuwonjezera pa valavu yosagwirana ndi dzimbiri, valve yosindikizira yofewa imatanthawuza spool kapena mpando wa chimodzi mwa zinthu ziwiri zomwe sizinali zitsulo (makamaka PTFE, rabara, ndi zina zotero. ) mawonekedwe osindikizidwa a valve. Kusindikiza kwa valavu yosindikizira ndikwabwinoko, koma pakuyika mapaipi, kuyeretsa dongosolo kumatha kusiya zinyalala zochulukirapo (monga kuwotcherera, zosefera zachitsulo, ndi zina zotero), zimadutsa mu valve yowongolera, zosavuta kukanda zofewa. chisindikizo mpando kapena spool, kotero kuti kutayikira kuchuluka kuchuluka, kudalirika kwa chisindikizo ndi osauka. Choncho, kusankha zofewa chisindikizo dongosolo ayenera kuganizira sing'anga kuyeretsa ndi okhwima payipi payipi pamaso ntchito. (2) Chosindikizira cholimba Chisindikizo cholimba komanso kuyika kwa aloyi osamva kuvala ndi njira yabwino yodulira ma valve. Njira imeneyi poganizira kusindikiza komanso kuganizira moyo utumiki ndi kudalirika, ngakhale index fakitale ndi 10-6 ~ 10-8 yekha, sangathe kukwaniritsa zotsatira zofewa chisindikizo kutayikira ziro, koma zokwanira kukwaniritsa zofunika kudula zolimba, ndipo ndizokhazikika, kuchokera kuzinthu zachuma ndizokwera mtengo kwambiri.
