Itandukaniro riri hagati yicyuma cyimyanda Valve hamwe n irembo ryibyuma bya Valve ibyiciro byugarije ikimenyetso cyo gufunga hejuru yicyuma kitagira umwanda "ububi".

Itandukaniro riri hagati yicyuma cyimyanda Valve hamwe n irembo ryibyuma bya Valve ibyiciro byugarije ikimenyetso cyo gufunga hejuru yicyuma kitagira umwanda "ububi".

Igice cyo gufungura no gufunga igice cyicyuma cyinjiriro nicyapa. Icyerekezo cyerekezo cyicyapa cyirembo ni perpendicular yerekeza kumazi. Irembo ry'irembo rishobora gukingurwa gusa no gufungwa byuzuye, ariko ntirishobora guhinduka no guterurwa. Ibice bibiri bifunga kashe ya rugi bifite ishusho. Inguni ya wedge iratandukanye nibipimo bya valve, mubisanzwe 50, na 2 ° 52 'mugihe ubushyuhe bwo hagati butari hejuru. Irembo rya wedge rishobora gukorwa muri rusange, ryitwa irembo rikomeye; Irashobora kandi gukorwa mu irembo rishobora kubyara ihindagurika kugira ngo ritezimbere ikoranabuhanga ryaryo kandi rishobore gutandukana no gufunga ubuso bwa Angle mu gihe cyo gutunganya. Ubu bwoko bw'irembo bwitwa irembo ryoroshye.

Gutondekanya ibyuma byinjira mumarembo
Shira irembo ryicyuma: ukurikije ibikoresho, hariho amarembo yicyuma cya karubone, icyuma cyinjiriro cyicyuma, icyuma giciriritse cyumubyimba wicyuma (icyuma cyinshi cyihanganira chromium molybdenum ibyuma biri muriki cyiciro), icyuma cyubushyuhe bwo hasi cyicyuma, nibindi.
Ubwoko butandukanye bwibyuma byinjira mumarembo bifite ibyiciro bitandukanye byihariye bikoreshwa muburyo bukurikira:
1. Icyuma cya karubone irembo rya valve amanota ni: WCA, WCB, WCC, LCB, nibindi. Ubushyuhe bukoreshwa-dogere 46 ~ dogere 425.
2. Ibyuma bitagira umuyonga amarembo ya valve: 301 ibyuma bitagira umuyonga, ibyuma bya CF8 bidafite ingese (bihwanye no guhimba ibyuma 304 bidafite ingese), CF8M ibyuma bidafite ingese (bihuye no guhimba ibyuma 316 bidafite ingese), nibindi. Ubushyuhe bukoreshwa-dogere198 ~ dogere 816.
3, icyuma giciriritse kigabanijwemo ubushyuhe bwo hejuru cyane hamwe nicyuma gike cyane, muribwo ibyuma byo mu rwego rwo hejuru byitwa chromium molybdenum ibyuma.
Chromium molybdenum ibyuma byamarembo ya valve amanota: ZG1Cr5Mo, ZG15Cr1MoV, ZG20CrMoV, WC6, WC9, C12A nibindi. Ubushyuhe bukoreshwa kuri dogere 550 kugeza kuri dogere 750.
Ubushyuhe bukoreshwa kuri buri cyiciro cyibikoresho biratandukanye, bitewe nakazi keza.

Uburyo bwo gukoresha intoki, gufata no kohereza ntibyemewe gukoreshwa mu guterura, kandi birabujijwe kugongana.
Inzugi ebyiri z'irembo zigomba gushyirwaho mu buryo buhagaritse (ni ukuvuga uruti mu mwanya uhagaze hamwe n'intoki hejuru).
Irembo ry'irembo hamwe na bypass bypass bigomba gufungurwa mbere yo gufungura (kuringaniza itandukaniro ryumuvuduko hagati yinjira no gusohoka no kugabanya imbaraga zo gufungura).
Irembo ry'irembo rifite uburyo bwo gutwara bizashyirwaho ukurikije amabwiriza y'ibicuruzwa.
Gusiga amavuta byibura rimwe mukwezi niba bikoreshwa kenshi no kuzimya.
Imiyoboro itemba, umuvuduko, kugenzura ubushyuhe bwibikorwa bitandukanye byo gutangiza inganda. Kurugero: ingufu z'amashanyarazi, metallurgie, peteroli, kurengera ibidukikije, gucunga ingufu, sisitemu yo gukingira umuriro nibindi. Kumwanya muremure, amarembo rusange akoreshwa kumasoko muri rusange aratemba cyangwa arangirika. Ibigo bimwe byinjiza tekinoroji yo mu Burayi ikorana buhanga na tekinoroji yo gukora valve kugirango ikore icyicaro cyoroshye cya kashe ya rugi, itsinze irembo rusange rya kashe ya kashe, ingese nizindi nenge. Icyicaro cya elastike kashe ya valve ikoresha plaque ya elastike kugirango itange umusaruro muke windishyi zidasanzwe zo guhindura ibintu kugirango bigerweho neza. Umuyoboro ufite ibyiza byo guhinduranya urumuri, kashe yizewe, kwibuka neza kwa elastique hamwe nubuzima bwa serivisi.
“Ibibi” byinshi bibangamira kashe ya kashe ya cyuma
Ibyuma bitagira umuyonga bivuga gukoresha ibikoresho byuma bidafite ingese bikozwe muri valve. Umuyoboro ni ikintu kigenzura muri sisitemu yo gutanga amazi. Byakoreshejwe muguhindura umuyoboro igice nicyerekezo cyurugendo rwikigereranyo. Ifite imirimo yo gutandukana, gukata, kugenzura, gutereta, kugenzura, guhagarika cyangwa kugabanya umuvuduko ukabije. Imyanya yo kugenzura amazi kuva kumurongo woroheje wisi kugeza kuri valve ikoreshwa muri sisitemu igoye cyane yo kugenzura ibintu muburyo butandukanye kandi bwihariye.
Ibyuma bitagira umuyonga hamwe numuyoboro cyangwa ibikoresho byimashini bihuza ni 304 ihuza ibyuma bitagira umuyonga, bikunze kwitwa 304 ibyuma bitagira ibyuma.
Ibyuma bitagira umuyonga bifata ibyuma bidafite ingese hamwe na hand, turbine, pneumatike, uburyo bwo kohereza amashanyarazi, hindura ibintu byoroshye kandi byoroshye. Imiterere yoroheje, uburemere bworoshye, byoroshye kubika ubushyuhe, byoroshye gushiraho. Uburyo bwo guhuza: gusudira, urudodo, flange kubakoresha guhitamo. Ifite imikorere myiza yo gufunga no kurwanya ruswa. Ibyuma bitagira umuyonga bikomeje kwinjiza ikoranabuhanga ryateye imbere mu mahanga, rifatanije n’imiterere nyayo y’iterambere ry’imbere mu gihugu, mu gihugu aho gutumizwa mu mahanga. Ikoreshwa muri gaze karemano, peteroli, gushyushya, imiti nu mashanyarazi hamwe nindi miyoboro ndende yohereza imiyoboro.
Kugeza ubu mugukoresha ibyuma bitagira umuyonga, umupira wumuringa wumuringa, icyuma cy irembo, isi yose ku isoko ukoresha cyane.
Ugereranije n'inganda gakondo, kubera imbogamizi ziranga imiterere, ntabwo ikwiriye guhangana nubushyuhe bwo hejuru, umuvuduko mwinshi no kurwanya ruswa, kurwanya imyenda nizindi nganda. Kwangirika kwubwoko bwose bwibice bigabanijwemo ibyiciro bibiri byangijwe numuntu kandi byangiritse, icyuma kitagira ibyuma ntigisanzwe, kwangirika kwa kamere, ni ukwambara kwa valve mubihe bisanzwe byakazi. Nibyangiritse byatewe no kwangirika byanze bikunze no gutwarwa nubuso bwa kashe hifashishijwe uburyo, bugabanijwemo ingingo zikurikira:
1. Kwishyiriraho no kubungabunga bidahagije
Iki kintu kiganisha kumurimo udasanzwe wubuso bwa kashe, na valve ikorana nindwara, bikaviramo guterana ku gahato no kwangirika hejuru yikimenyetso. Imikorere nyamukuru nuko valve idatoranijwe ukurikije uko akazi kameze, kandi na valve ya troncation ikoreshwa nka trottle valve, biganisha kumuvuduko wa kashe nini cyane kandi kashe irihuta cyane cyangwa gufunga ntabwo bikomeye, kubwibyo ko ubuso bwa kashe bwangiritse kandi bwambarwa.
2. Guhitamo nabi no gukora nabi
Ahanini ntabwo ukurikije imiterere yakazi hanyuma uhitemo valve, nka valve ya troncation iyo valve ya trottle ikoreshejwe, bikaviramo umuvuduko wo gufunga ni munini cyane kandi gufunga byihuse cyangwa gufunga ntibikomeye, kuburyo hejuru yikimenyetso cya isuri no kwambara. Cyangwa icyuma gikozwe mucyuma gikoreshwa mubitangazamakuru byangirika, cyangwa valve idashobora ubushyuhe ikoreshwa mubihe by'ubushyuhe bwo hejuru. Cyangwa ibintu rusange bifunga ibimenyetso bifatika bikoreshwa ahantu hamwe n’umwanda mwinshi nubushyuhe bwo hejuru.
3. Isuri yo hagati
Nibisubizo byo kwambara, gukaraba no gutobora hejuru yikidodo mugihe uburyo bukora. Ku muvuduko runaka, uduce duto duto twa planktike hagati turenga hejuru yikimenyetso, bigatera kwangirika kwaho. Umuvuduko mwinshi wihuta wogeje neza kashe, bigatera kwangirika kwaho. Iyo uburyo buvanze kandi bukavamo umwuka, guturika kwinshi kurakara bigira ingaruka hejuru yubuso bwa kashe, bigatera kwangirika kwaho. Isuri yikigereranyo ihujwe nigikorwa cyo guhinduranya isuri yimiti bizangiza cyane kashe.
4. Isuri y'amashanyarazi
Ubuso bwa kashe burahuza nundi, ubuso bwa kashe burahuza numubiri wa kashe hamwe numubiri wa valve, hamwe nubudasa bwikwirakwizwa ryikigereranyo, itandukaniro rya ogisijeni nizindi mpamvu, bizatanga itandukaniro rishobora kubaho, isuri yamashanyarazi , bikaviramo isuri kuruhande rwa anode yubuso bwa kashe.
