Chisimbiso chepamusoro chevhavha chinowanzosvibiswa, chinoputika uye chinopfekwa nepakati, saka chikamu chinokanganisa nyore nyore pavhavha.Zvakadai sepneumatic ball valve uye yemagetsi butterfly valve uye mamwe mavharuvhu otomatiki, nekuda kwekugara uye nekukurumidza kuvhura nekuvhara, kunaka kwavo uye hupenyu hwebasa zvinokanganiswa zvakananga.Chinhu chikuru chinodiwa chevhavha chisimbiso chepamusoro ndechekuti vheji inogona kuve yakachengeteka uye yakavimbika chisimbiso pasi pemamiriro ekushanda akataurwa.Naizvozvo, zvinhu zvepasi zvinofanira kunge zvine zvinotevera zvinhu:
(1) Kuita kwakanaka kwekuisa chisimbiso, ndiko kuti, nzvimbo yekuisa chisimbiso inofanira kukwanisa kudzivirira kubuda kwepakati;
(2) Iine rimwe simba, nzvimbo yekuisa chisimbiso inofanirwa kumirisana neiyo chaiyo yekumanikidza kukosha kwechisimbiso chakaumbwa nepakati pesimba musiyano;
(3) Corrosion resistance, pasi pebasa renguva refu rekuora kwepakati uye kushushikana, nzvimbo yekuisa chisimbiso inofanira kunge iine corrosion resistance inowirirana nezvinodiwa zvekugadzira;
(4) Kugona kurwisa zvikwekwe, kuvhara kwevharuvhu zvese zvisimbiso zvine simba, uye pane kukakavara pakati pekuisa chisimbiso panguva yekuvhura nekuvhara maitiro;
(5) Erosion resistance, nzvimbo yakavharidzirwa inofanira kukwanisa kurwisana nekukukurwa kwepamusoro-speed media uye kudhumhana kwezvikamu zvakasimba;
(6) Kugadzikana kwakanaka kwekushisa, nzvimbo yekuisa chisimbiso inofanira kuva nesimba rakakwana uye oxidation kuramba pakupisa kwepamusoro, uye inofanira kuva nechando chakanaka chekudzivirira brittle pane tembiricha yakaderera;
(7) Kushanda kwakanaka kwekugadzirisa, nyore kugadzira nekuchengetedza, valve inoshandiswa sechinhu chikuru-chinangwa chechikamu, uye inovimbiswa kuva nehuwandu hwehupfumi.
Mamiriro ekushandisa uye misimboti yekusarudza yevhavha yekuisa chisimbiso pamusoro pezvinhu.Iyo yekuisa chisimbiso pamusoro zvinhu zvakakamurwa kuita mapoka maviri: simbi uye isiri-simbi.Mamiriro ezvinhu anoshanda ezvinowanzo shandiswa zvinhu ndeaya anotevera:
(1) Rabha.Inowanzo shandiswa pakuisa chisimbiso chepasi-kudzvanya-yakavharika mavharuvhu egedhi, diaphragm mavharuvhu, butterfly mavharuvhu, cheki mavharuvhu uye mamwe mavharuvhu.
(2) Purasitiki.Mapurasitiki anoshandiswa pakuisa chisimbiso ndeanylon uye PTFE, ane hunhu hwekusagadzikana kwegora uye diki friction coefficient.
(3) Babbitt.Iyo inozivikanwawo sekubereka alloy, ine yakanaka corrosion kuramba uye yakanaka yekumhanya-mu kugona.Inokodzera nzvimbo yekuvhara yevhavha yevhavha yevhavha yeammonia ine simba shoma uye tembiricha ye -70-150 ℃.
(4) Copper alloy.Iyo ine yakanaka yekupfeka kusagadzikana uye kumwe kupisa kupisa.Inokodzera globe valve, cast iron gedhi vharafu uye cheki vharafu, etc. Inowanzo shandiswa kumvura uye chiutsi nekudzika kwakadzika uye tembiricha kwete yakakwirira kupfuura 200 ℃.
(5) Chrome-nickel simbi isina tsvina.Iine good corrosion resistance, inodzivirira kuvhuvhuta uye kudzivirira kupisa.Inokodzera midhiya senge vapor nitric acid.
(6) Chrome simbi isina tsvina.Iyo ine yakanaka corrosion resistance uye inowanzo shandiswa mumavharuvhu ane high pressure uye tembiricha isingakwire kupfuura 450 ℃ yemafuta, mhute yemvura uye mamwe midhiya.
(7) High chromium pamusoro pesimbi.Iyo ine yakanaka corrosion resistance uye kushanda kuomarara kuita, uye inokodzera kukwira kwepamusoro, tembiricha yakakwira oiri, steam uye mamwe midhiya.
(8) Nitrided simbi.Iyo ine yakanaka corrosion resistance uye scratch resistance, uye inowanzo shandiswa mune thermal power station station mavharuvhu.Ichi chinyorwa chinogona zvakare kusarudzwa kune sphere yeakaomeswa-akavharwa bhora mavharuvhu.
(9) Carbide.Iyo ine yakanaka yakazara zvimiro senge corrosion resistance, kukukurwa kwevhu uye kuramba kukwenya, uye ine hupenyu hurefu hwesevhisi.Icho chinhu chakakodzera chekuisa chisimbiso.Inowanzo shandiswa tungsten drill alloy uye drill base alloy surfacing electrodes, nezvimwewo, inogona kugadzira yakanyanya-yakanyanya kudzvanywa, yekupedzisira-yepamusoro tembiricha yekuisa chisimbiso pamusoro, yakakodzera mafuta, oiri, gasi, hydrogen uye mamwe midhiya.
(10) Pfapfaidza welding alloy.Kune cobalt-based alloys, nickel-based alloys, uye chin-based alloys, ane yakanaka corrosion resistance uye kusapfeka.
Kuti uve nechokwadi chekuchengetedzwa uye kuvimbika kwevhavhavhavha chisimbiso, zvinhu zvakasarudzwa zvinofanira kugadziriswa maererano nemamiriro ezvinhu chaiwo ekushanda.Kana iyo yepakati ichinyanya kukanganisa, pakusarudza zvinhu, inofanirwa kusangana neiyo corrosive performance pakutanga, yozosangana nezvinodiwa zvezvimwe zvinhu;Chisimbiso chevhavha yegedhi inofanira kubhadhara kune yakanaka scratch resistance;Mavharuvhu ekuchengetedza, mavharuvhu ekudzivirira uye mavharuvhu ekudzora anonyanya kunyungudika nepakati, uye zvinhu zvine corrosion inodzivirira zvakanaka zvinofanirwa kusarudzwa;Nokuda kwechimiro chakabatanidzwa chemhete yekuisa chisimbiso uye muviri, zvinhu zvine kuoma kwepamusoro zvinofanira kuonekwa sechisimbiso chepamusoro;Mavharuvhu akazara ane tembiricha yakaderera uye kudzvanywa anofanirwa kusarudza rabha nepurasitiki ine yakanaka yekuisa chisimbiso kuita sechisimbiso;Paunosarudza zvinhu zvekuisa chisimbiso, zvinofanira kuonekwa kuti kuoma kwepamusoro pechigaro chevhavha kunofanira kunge kwakakwirira kudarika iyo yekuvhara pamusoro pevhavha disc.
