Munzira yekufambisa mvura,Vharuvhu Yekupisa Kwakanyanyachinhu chakakosha chekudzora, icho chinonyanya kuita mabasa ekudzora, kutsausa, kudzivirira kudzokera shure, kuchekwa, uye shunt. Vharuvhu iyi inoshandiswa zvakanyanya mumaindasitiri nematunhu ehurumende. Vharuvhu yekupisa kwakanyanya imhando inowanzoshandiswa mumavharuvhu. Hunhu hwayo hwakasiyana ndehwekuti: kushanda zvakanaka kwekudzima, kudzimwa kwakadzika kunogona kuitwa; kuchinjika kwakanaka; kunyungudika kwakanaka kwekukanganisa, zvakaoma kuikuvadza nechisimba; Kusasimba kwehasha kunowanzova kushoma nezvimwewo. Kune mhando dzakawanda dzevharuvhu dzekupisa kwakanyanya. Dzakajairika ndedzekupisa kwakanyanyaMavharuvhu eshavishavi, tembiricha yakakwiraMavharuvhu ebhora, mafirita anodziya zvakanyanya, uye anodziya zvakanyanyaMavharuvhu egedhi.
Ndeapi marudzi evharuvhu eHigh Temperature Valve?
Mavharuvhu ekupisa kwakanyanya anosanganisira mavharuvhu egedhi anodziya zvakanyanya, mavharuvhu anodzima kupisa kwakanyanya, mavharuvhu ekutarisa kupisa kwakanyanya, mavharuvhu ebhora anodziya zvakanyanya, mavharuvhu eshavishavi anodziya zvakanyanya, mavharuvhu etsono anodziya zvakanyanya, mavharuvhu etsono anodziya zvakanyanya, mavharuvhu ekudzikisa kupisa kwakanyanya, uye mavharuvhu ekuderedza kumanikidzwa kupisa kwakanyanya. Pakati pawo, anonyanya kushandiswa mavharuvhu egedhi, mavharuvhu eglobe, mavharuvhu ekuongorora, mavharuvhu ebhora uye mavharuvhu eshavishavi.
Ndezvipi Zvinodiwa Pakushanda Kwemavharuvhu Ekupisa Kwakanyanya?
Mamiriro ekushanda ekupisa kwakanyanya anosanganisira kupisa kwakanyanya, kupisa kwakanyanya Ⅰ, kupisa kwakanyanya Ⅱ, kupisa kwakanyanya Ⅲ, kupisa kwakanyanya Ⅳ, uye kupisa kwakanyanya Ⅴ, izvo zvichatsanangurwa zvakasiyana pazasi.
Tembiricha yakaderera
Kupisa kwakanyanya kunoreva kuti tembiricha yekushanda kwevharuvhu iri munzvimbo ye325 ～ 425 ℃. Kana chinhu chiri mumvura neutsi, WCB, WCC, A105, WC6 neWC9 ndizvo zvinonyanya kushandiswa. Kana chinhu chiri mafuta ane sarufa, C5, CF8, CF3, CF8M, CF3M, nezvimwewo, izvo zvinodzivirira ngura yesulfide, zvinonyanya kushandiswa. Zvinonyanya kushandiswa mumidziyo inoderedza kumanikidzwa uye michina inononoka kubikwa muzvicherwa. Panguva ino, mavharuvhu akagadzirwa neCF8, CF8M, CF3 uye CF3M haashandiswi kudzivirira ngura yeasidhi, asi anoshandiswa kune zvigadzirwa zvemafuta zvine sarufa uye mapaipi emafuta negasi. Mumamiriro ezvinhu aya, tembiricha yepamusoro yekushanda yeCF8, CF8M, CF3 uye CF3M i450 ° C.
Tembiricha yepamusoro Ⅰ
Kana tembiricha yekushanda kwevharuvhu iri 425 ～ 550 ℃, ikirasi yepamusoro-soro I (inonzi kirasi yePI). Chinhu chikuru chevharuvhu yePI grade isimbi "yekupisa kwakanyanya Ⅰ grade medium carbon chromium nickel rare earth titanium high quality heat-resistant steel" ine CF8 sechimiro chekutanga muASTMA351 standard. Nekuti giredhi rePI izita rakakosha, pfungwa yesimbi isina ngura inodziya zvakanyanya (P) inosanganisirwa pano. Saka, kana nzvimbo yekushanda iri mvura kana utsi, kunyangwe simbi yekupisa yakanyanya WC6 (t≤540 ℃) kana WC9 (t≤570 ℃) inogonawo kushandiswa, nepo zvigadzirwa zvemafuta zvine sulfur zvinogonawo kushandiswa simbi yekupisa yakanyanya C5 (ZG1Cr5Mo), asi hazvigone kunzi PI-class pano.
Kupisa kwakanyanya II
Tembiricha yekushanda kwevharuvhu i550 ～ 650 ℃, uye inoiswa muchikamu chekupisa kwakanyanya Ⅱ (inonzi P Ⅱ). Vharuvhu yekupisa kwakanyanya yekirasi yePⅡ inonyanya kushandiswa mumidziyo inochenesesa mafuta akawanda. Ine vharuvhu yegedhi isingatsvedzeri kupisa kwakanyanya inoshandiswa mumuromo wekutenderera katatu nezvimwe zvikamu. Chinhu chikuru chevharuvhu yePⅡ grade i“simbi inodziya zvakanyanya Ⅱ grade medium carbon chromium nickel rare earth titanium tantalum reinforced heat-resistant” ine CF8 sechimiro chayo muASTMA351 standard.
Kupisa kwakanyanya III
Tembiricha yekushanda kwevharuvhu iyi i650 ～ 730 ℃, uye inoiswa muchikamu chekupisa kwakanyanya III (chinonzi PⅢ). Mavharuvhu ekupisa kwakanyanya ekirasi yePⅢ anonyanya kushandiswa mumayuniti makuru ekugadzira mafuta anorema muminda yekuchenedza. Chinhu chikuru chevharuvhu yekupisa kwakanyanya yekirasi yePⅢ iCF8M yakavakirwa paASTMA351.
Kupisa kwakanyanya Ⅳ
Tembiricha yekushanda kwevharuvhu i730 ～ 816 ℃, uye inoonekwa seyepamusoro-soro IV (inonzi PIV muchidimbu). Muganho wepamusoro wetembiricha yekushanda yevharuvhu yePIV i816 ℃, nekuti tembiricha yepamusoro inopihwa neASMEB16134 pressure-tembiricha grade yakasarudzwa yekugadzira vharuvhu i816 ℃ (1500υ). Pamusoro pezvo, mushure mekunge tembiricha yekushanda yapfuura 816 ° C, simbi inenge yava pedyo nekupinda munzvimbo yekupisa. Panguva ino, simbi iri munzvimbo yepurasitiki, uye simbi ine plasticity yakanaka, uye zvakaoma kutsungirira kumanikidzwa kwakanyanya kwekushanda uye simba rekurova uye kudzivirira kuti isakanganiswe. Chinhu chikuru chevharuvhu yeP Ⅳ iCF8M muASTMA351 standard sechimiro chekutanga "tembiricha yepamusoro Ⅳ medium carbon chromium nickel molybdenum rare earth titanium tantalum reinforced heat-resistant steel". CK-20 neASTMA182 standard F310 (kusanganisira C content ≥01050%) uye F310H simbi isingatsvi isingapisi.
Tembiricha yepamusoro Ⅴ
Tembiricha yekushanda kwevharuvhu yakakwira kupfuura 816 ℃, inonzi PⅤ, vharuvhu yePⅤ high temperature (yevharuvhu dzinovhara, kwete dzinodzora mavharuvhu emabhatafura) inofanira kushandisa nzira dzakasarudzika dzekugadzira, dzakadai se lining insulation lining kana mvura kana gasi. Kutonhodza kunogona kuve nechokwadi chekuti vharuvhu inoshanda zvakanaka. Nokudaro, muganho wepamusoro wekushanda kwevharuvhu yePⅤ class high temperature hauna kutaurwa, nekuti tembiricha yekushanda yevharuvhu yekudzora haingotariswi chete nezvinhu, asiwo nenzira dzakasarudzika dzekugadzira, uye musimboti wekutanga wenzira yekugadzira wakafanana. Vharuvhu yePⅤ grade high temperature inogona kusarudza zvinhu zvine musoro zvinogona kusangana nevharuvhu zvichienderana nekushanda kwayo uye kushanda kwesimba uye nzira dzakasarudzika dzekugadzira. Muvharuvhu yePⅤ class high temperature, kazhinji vharuvhu yeflapper kana butterfly yevharuvhu yeflue flapper kana butterfly inowanzo sarudzwa kubva kuHK-30 neHK-40 high-temperature alloys muASTMA297 standard. Inodzivirira ngura, asi haigone kutsungirira kuvhunduka uye kumanikidzwa kwakanyanya.
