Stainless simbi mavharuvhu akanyatsokodzera kushandiswa mukuora mapaipi uye chiutsi mapaipi. Vane hunhu hwekuramba corrosion, high tembiricha kuramba uye high pressure resistance. Iwo anowanzo shandiswa mumapaipi anoparadza mumiti yemakemikari, uye mapaipi mumvura yepombi kana zvidyarwa zvekudya. Carbon simbi mavharuvhu haana corrosion resistance uye anogona chete kushandiswa asiri-corrosive medium pipelines senge chiutsi, mafuta, mvura, etc. Mutengo wemavharuvhu ecarbon simbi wakaderera pane wesimbi isina tsvina, saka kazhinji hapana chiutsi chinopisa nezvimwe. mapaipi anoshandiswa. Carbon simbi inoshandiswa, uye mavharuvhu esimbi uye zvimwe zvinhu zvinoshandiswa pakuora. Iyi inotevera tsananguro pfupi yesarudzo yekushandiswa kwesimbi isina simbi yepakati-vharuvhu uye kabhoni simbi gedhi vharafu neNSW Valve:
1 Chii chikonzero chekudonha kwekabhoni simbi valve
Carbon steel gedhi vharafu ivharuvhu yeindasitiri, inoshandiswa zvakanyanya mupetroleum, makemikari, chiteshi chemagetsi uye mamwe maindasitiri. Iyo ine zvakanakira otomatiki, nyore kushanda, uye hupenyu hurefu hwebasa, asi kana uchishandisa
Munguva yemaitiro, nekuda kwepesvedzero yega kana yekunze zvinhu, iyo kabhoni simbi gedhi vharafu inodonha. Saka, chii chikonzero chekudonha kwekabhoni simbi gedhi valve? Pfungwa huru ndedzinotevera
zvikonzero zvakajairika.
1. Iyo yakaderera yekugadzirisa yakanyatsojeka yewedge-yakaita sealing chisimbiso mhete inotungamirira kune mukati mekuputika kwe carbon steel gedhi valve. Chero bedzi gedhi regedhi rechiratidzo chikuru rakasarudzwa, kunaka kwezvikamu zvakasara zvinowanzova nani, kuitira kuti kunyatsogadziriswa kwemhete yekuisa chisimbiso kusave kwakaderera.
1. Kusagadzikana kwekugadzirwa uye kushandiswa kwemamiriro ezvinhu kunotungamirira mukati mekuputika kwevhavha yegedhi. Ivhavha yegedhi ine zvidikanwi zvakakwirira pane nzvimbo yekushanda. Kana kudzvinyirirwa uye tembiricha nharaunda isina kugadzikana uye shanduko yekuchinja yakakurisa, iyo inokonzeresa yekumanikidza painovhara mhete ichave yakakura, iri nyore kwazvo. Deformation inoitika, iyo inozopedzisira yatungamira kune kuvuza kwevhavha.
3. Kusagadzikana kwehutano hwehutano hwevhavha kunotungamirira kukuputika kwemukati kwevhavha yegedhi. Vamwe vashandi havachenese nzvimbo yekuvharisa yemhete yekuisa chisimbiso pakugadzirisa valve. Kuvapo kwetsvina kuchakanganisa kushanda kwevhavha. Mukufamba kwenguva, nzvimbo yekuisa chisimbiso ichave yakakweshwa, izvo zvinozoita kuti valve ibude.
4. Mhete yekuvhara-yakaita ngura yenhovo inoita kuti vharafu yegedhi ibude kwenguva yakareba. Pasi pesimba repakati, mhete yekuvhara inosvibiswa nyore nyore. Kana ngura ikasvika pane imwe nhanho, mhete yekuisa chisimbiso ichaziviswa, kuitira kuti vharafu ibude.
5. Muviri wevharuvhu hauna kukwana. Kana muviri wevhavha une matambudziko akadai se pores, slag inclusions, kuputika, maburi ejecha, nezvimwewo, ipapo gedhi regedhi rinotarisana nekubuda kwekunze panguva yekushandiswa.
Muchidimbu, kubuda kwekabhoni simbi gedhi vharafu idambudziko rakajairika. Kana paine kuvuza, inoisa mungozi kuchengetedzwa kwemidziyo nevashandi, saka zvinodikanwa kutsvaga chikonzero uye kugadzirisa dambudziko nenguva.
4 Nzira yekusarudza yakavimbika Stainless simbi valve
Yakasiyana neyakajairwa pneumatic bhora vharafu, yemagetsi butterfly vharafu uye mamwe mavharuvhu zvishandiso, gedhi chizvarwa hachidi kugadzirisa kuyerera kwemvura yakaoma yepakati, asi inoita seyakazaruka yakazara uye yakazara yakagurwa mupombi.
Gedhi rekuchinja rinoshandiswa. Saka pane mavharuvhu emagedhi akawanda esimbi pamusika, ndechipi chigadzirwa chinonyanya kuvimbika? Hunhu hwesimbi isina tsvina yegedhi mavharuvhu
Stainless simbi inogadzirwa nesimbi isina tsvina. Simbi yemhando yepamusoro uye kurapwa kwepamusoro uye kudzima nekupisa zvinotsiva zvinoita kuti simbi isina tsvina ive yakanaka anti-corrosion zvikamu uye kunaka kwakanaka.
Abrasion, yakasimba kwazvo. Nokudaro, simbi isina tsvina yegedhi valve inowanzoshandiswa kudzora kuyerera kwemakemikari, uye kuvhara kwayo kwakanaka uye kusagadzikana kwekuora kunoita kuti zvive nyore kuputika uye kushambidzwa nepakati.
Kupisa kwepamusoro uye kudzvinyirira kwakanyanya murume anogona zvakare kuve nechokwadi chekuisa chisimbiso kuita kwakanaka. Ndeipi simbi isina tsvina yegedhi valve iri nani
Zvinonzi Stainless simbi gedhi vharafu ingori indasitiri vharafu mudziyo, asi chaizvoizvo zvikuru hanya. Semuenzaniso, kana kusarudzwa kwevhavha yegedhi kusina kunaka, njodzi dzisingatarisirwi dzinogona kuitika, saka usaita
Ivhavha yegedhi yesimbi isina tsvina inofanira kuongororwa isati yabuda mufekitari. Paunenge uchitenga vheji, mutengi anofanirawo kuona kumanikidzwa kwemhando iyo valve inoda kumira mberi kuti isarudze muenzaniso wakakodzera uye tsanangudzo.
Vagadziri venguva dzose vanonyanya kuomesera uye vakaringana mukumanikidza kuyedzwa, saka ingave iyo mhando yevhavha, hupenyu hwesevhisi, mutengo-unoshanda, kana kuchengetedza kuita.
Zvinonyanya kukosha kusarudza mugadziri wenguva dzose uye akavimbika, uye zvigadzirwa zvevagadziri venguva dzose (NSW Valve) zvakachengeteka zvakanyanya.
Mutengi wega wega ane zvakasiyana zvinodiwa kune yakaoma Stainless simbi gedhi mavharuvhu. Panyaya yemutengo, kunaka uye kuchengetedzwa kwechiratidzo, vagadziri vakasiyana dzimwe nguva vane misiyano iri pachena. Nokudaro, kusarudzwa kwevagadziri kunofanira kufunga zvakasiyana-siyana.
