Chinangwa chekushandisa vharuvhu rekutarisa ndechekudzivirira kuyerera kwemedium, uye vharuvhu rekutarisa rinowanzoiswa panzvimbo inobuda pombi. Pamusoro pezvo, vharuvhu rekutarisa rinofanirawo kuiswa panzvimbo inobuda compressor. Muchidimbu, kudzivirira kuyerera kwemedium, vharuvhu rekutarisa rinofanira kuiswa pamidziyo, mudziyo kana mapaipi.
Kazhinji, mavharuvhu ekutarisa anosimudza anoshandiswa pamapaipi akatambanuka ane dhayamita ye50mm. Vharuvhu yekutarisa inosimudza yakatwasuka inogona kuiswa pamapaipi akatambanuka uye akatwasuka. Vharuvhu yepasi inowanzoiswa chete papaipi yakatambanuka yepombi inopinza, uye medium inoyerera kubva pasi kuenda kumusoro.
Vharuvhu yekutarisa inotenderera inogona kugadzirwa kuti ive nesimba rekushanda rakakwirira kwazvo, PN inogona kusvika 42MPa, uye DN inogonawo kugadzirwa yakakura kwazvo, simba rekushanda rinogona kusvika kupfuura 2000mm. Zvichienderana nezvinhu zvakasiyana zvegoko nechisimbiso, inogona kushandiswa kune chero chinhu chinoshanda uye chero tembiricha yekushanda. Chinhu ichi imvura, utsi, gasi, chinhu chinopisa, mafuta, chikafu, mushonga, nezvimwewo. Tembiricha yekushanda yechinhu ichi iri pakati pe -196~800℃.
Nzvimbo yekuisa vharuvhu yekutarisa swing haina kuganhurirwa, inowanzoiswa papombi yakatwasuka, asi inogonawo kuiswa papombi yakatwasuka kana paipi yakatsveyama.
Nguva yakakodzera yekuvhara vharuvhu rekuongorora mabhuruvhu ndeyekumanikidzwa kwakaderera uye dhayamita hombe, uye nguva yekuisa yakaganhurirwa. Nekuti kumanikidzwa kwekushanda kwevharuvhu rekuongorora mabhuruvhu hakugone kuve kwakakwira zvakanyanya, asi dhayamita yepakati inogona kunge yakakura kwazvo, iyo inogona kusvika kupfuura 2000mm, asi kumanikidzwa kwepakati kuri pasi pe6.4MPa. Vharuvhu rekutarisa mabhuruvhu rinogona kugadzirwa kuita wafer, iyo inowanzoiswa pakati pemaflange maviri epaipi nenzira yekubatanidza wafer.
Nzvimbo yekuiswa kwevharuvhu yekuongorora butterfly haina muganho, inogona kuiswa papombi yakatwasuka, pombi yakatwasuka kana pombi yakatsveyama.
Vharuvhu yekutarisa diaphragm yakakodzera mapaipi anowanzobatwa nehammer yemvura. Diaphragm inogona kubvisa hammer yemvura inokonzerwa nekudzokera shure kwemedium. Sezvo tembiricha yekushanda uye kumanikidzwa kwekushanda kwemavalvu ekutarisa diaphragm zvichiganhurirwa nezvinhu zve diaphragm, zvinowanzo shandiswa mumapaipi ane kumanikidzwa kwakaderera uye tembiricha yakajairika, kunyanya pamapaipi emvura yepombi. Kazhinji, tembiricha yekushanda yemedium iri pakati pe -20~120℃, uye kumanikidzwa kwekushanda kuri pasi pe1.6MPa, asi diaphragm check valve inogona kusvika padhayamita yakakura, uye DN yepamusoro inogona kupfuura 2000mm.
Vharuvhu yekutarisa diaphragm yave ichishandiswa zvakanyanya mumakore achangopfuura nekuda kwekushanda kwayo kwakanaka kwemvura, chimiro chayo chiri nyore uye mutengo wakaderera wekugadzira.
Vharuvhu yekutarisa bhora ine mashandiro akanaka ekuvharira, inoshanda zvakanaka uye inodzivisa mvura nenyundo nekuti chisimbiso chacho ibhora rakafukidzwa nerabha; uye nekuti chisimbiso chacho chinogona kuva bhora rimwe chete kana mabhora akawanda, chinogona kugadzirwa kuita dhayamita hombe. Zvisinei, chisimbiso chacho ibhora risina chinhu rakafukidzwa nerabha, iro risingakodzeri mapaipi ane simba guru, asi rakakodzerwa chete nemapaipi ane simba repakati nepasi.
Sezvo ganda revharuvhu rekutarisa bhora richigona kugadzirwa nesimbi isingatsvi, uye bhora risina chinhu rechisimbiso rinogona kufukidzwa nepurasitiki yePTFE engineering, rinogonawo kushandiswa mumapaipi ane general corrosive media.
Tembiricha yekushanda kwerudzi urwu rwe check valve iri pakati pe -101~150℃, kumanikidzwa kwe nominal kuri ≤4.0MPa, uye huwandu hwe nominal dhayamita huri pakati pe200~1200mm.
Nguva yekutumira: Kurume-23-2022
