1.Ibisobanuro bya valve valve
Nubwoko bwa valve ikoreshwa cyane mumuyoboro. Ifite cyane cyane uruhare rwo guhuza no guca hagati. Ntibikwiye kugenzurwa nigipimo cyikigereranyo cyikigereranyo, ariko kirashobora gusuzuma igipimo cyurugendo ukurikije izamuka nigabanuka ryuruti (urugero: urugamba rwo kurwanya umuriro wintebe yintebe yumuryango hamwe no gufungura no gufunga). Ugereranije nibindi byuma, amarembo y amarembo afite intera nini yo gukoreshwa kumuvuduko, ubushyuhe, kalibiri nibindi bisabwa.
2. Imiterere y'Irembo
Irembo ry'irembo rishobora kugabanwa muburyo bwa wedge, ubwoko bumwe bwirembo, ubwoko bw irembo rya elastike, ubwoko bw amarembo abiri nubwoko bw amarembo abangikanye ukurikije imiterere yimbere.
Ukurikije itandukaniro ryinkunga yibiti, irashobora kugabanywamo amarembo yimeza yuguruye hamwe numuryango wijimye wijimye.
3. Hindura umubiri n'umwiruka
Imiterere yumuryango wa valve igena isano iri hagati yumubiri wa valve numuyoboro, umubiri wa valve nigifuniko. Kubijyanye nuburyo bwo gukora, hariho gutara, guhimba, guhimba, guta no gusudira, hamwe no gusudira amasahani. Gukora valve umubiri wateye imbere kuri kalibiri nini, mugihe umubiri wa casting wateye imbere buhoro buhoro kugeza kuri kalibiri nto. Ubwoko ubwo aribwo bwose bw'irembo valve irashobora guhimbwa cyangwa guterwa, ukurikije ibyo uyikoresha asabwa hamwe nuburyo bwo gukora bufitwe nuwabikoze.
Inzira itembera yumuryango wa valve valve irashobora kugabanywamo ubwoko bubiri: ubwoko bwa diameter yuzuye nubwoko bwagabanutse. Diameter ya nomero yumurongo utemba usanga ahanini ari kimwe na diametre nominal ya valve, na diameter ntoya yumurongo utemba kuruta diameter nominal ya valve yitwa ubwoko bwa diameter bwagabanutse. Hariho ubwoko bubiri bwimiterere yo kugabanuka: kugabanuka kimwe no kugabanuka kimwe. Umuyoboro wafashwe ni kugabanya diameter idasanzwe. Ubuso bwimbere bwimbere yubwoko bwa valve burasa cyane na diameter nominal, hanyuma buhoro buhoro bugabanuka kugeza byibuze ku ntebe.
Ibyiza byo gukoresha shrinkage yiruka (yaba umuyoboro wa conical udahuzagurika cyangwa kugabanuka kimwe) nubunini bumwe bwa valve, bushobora kugabanya ubunini bw irembo, gufungura no gufunga imbaraga nigihe. Ingaruka ni uko kurwanya umuvuduko byiyongera, kugabanuka k'umuvuduko no gukoresha ingufu byiyongera, bityo umwobo wo kugabanuka ntugomba kuba munini cyane. Kugabanya ibipimo bya diameter ya diameter, igipimo cya diameter y'imbere yintebe na diameter nominal ni 0.8-0.95. Kugabanya indangagaciro zifite diameter iri munsi ya 250mm muri rusange zifite intebe yimbere imbere yimbere igikoresho kimwe kiri munsi ya diameter; Kugabanya indanga zifite diameter nominal zingana cyangwa zirenga mm 300 muri rusange zifite intebe yimbere ya diameter imbere ibikoresho bibiri munsi ya diameter.
4. Kwimuka kumarembo
Iyo valve y irembo ifunze, hejuru yikidodo gishobora gufungwa gusa nigitutu giciriritse, ni ukuvuga, gusa nigitutu giciriritse kugirango ukande hejuru yikimenyetso cy irembo kugera kuntebe kurundi ruhande kugirango harebwe kashe, ni kashe. Ibyinshi mumarembo ahatirwa gufunga, ni ukuvuga, iyo valve ifunze, irembo rigomba guhatirwa kuntebe nimbaraga ziva hanze kugirango harebwe kashe.
Uburyo bwo kugenda: Irembo ryurugi rwinjiriro rugenda kumurongo ugororotse hamwe nigiti, bizwi kandi ko gufungura amarembo yumuryango. Mubisanzwe hariho insinga za trapezoidal kurinkoni yo guterura. Binyuze mu mbuto hejuru ya valve hamwe nuyobora umurongo ku mubiri wa valve, icyerekezo kizunguruka gihinduka umurongo ugororotse, nukuvuga, torque ikora ihindurwamo imbaraga. Iyo ufunguye valve, iyo uburebure bwo kuzamura irembo bingana na 1: 1 inshuro ya diameter ya valve, inzira itemba irakinguye rwose, ariko iyo ikora, iyi myanya ntishobora gukurikiranwa. Mu mikoreshereze ifatika, vertex yikibaho cya valve ikoreshwa nkikimenyetso, ni ukuvuga, umwanya wikibaho cya valve itimuka ikoreshwa nkumwanya wuzuye wuzuye. Kugirango dusuzume ibintu bifunga byimpinduka zubushyuhe, ubusanzwe valve ifungurwa kuri vertex hanyuma igasubira kuri 1 / 2-1 ihinduka nkumwanya wa valve ifunguye neza. Kubwibyo, imyanya yuzuye ya valve igenwa nu mwanya w irembo (ni ukuvuga inkoni). Amarembo amwe n'amwe y'ibiti byashyizwe ku isahani y'irembo. Kuzunguruka intoki bituma uruti ruzunguruka, ruzamura isahani. Ubu bwoko bwa valve bwitwa rotary stem gate valve cyangwa umwijima wijimye wijimye.
5. Ibyiza byo gukora mumarembo
1.
2. Gufunga imikorere nibyiza kuruta globe yisi, kandi gufungura no gufunga ni byinshi bizigama umurimo kuruta isi ya valve.
3. Urutonde runini rwa porogaramu, usibye amavuta, amavuta nibindi bitangazamakuru, ariko kandi birakwiriye kubiciriritse birimo ibinini bya granulaire hamwe nubukonje bwinshi, nabyo bikwiriye gukoreshwa nka valve valve na sisitemu ya vacuum nkeya;
4. Kubwibyo, amarembo ya valve akwiriye imiyoboro aho imiyoboro ishobora guhindura icyerekezo, kandi biroroshye kuyishyiraho.
6. Amakosa yo gukora amarembo ya valve
1.Ibishushanyo mbonera bihanitse kandi birebire byo gutangira no gufunga. Iyo ufunguye, birakenewe kuzamura isahani ya valve mugice cyo hejuru cyicyumba cya valve, kandi mugihe ufunze, birakenewe ko umanika ibyapa byose bya valve mumwanya wintebe, bityo gufungura no gufunga icyapa cya valve nini. kandi igihe ni kirekire.
2. Kubera ubushyamirane buri hagati yubuso bubiri bwa plaque ya plaque nintebe ya valve mugikorwa cyo gufungura no gufunga, ubuso bwa kashe biroroshye gushushanya, bigira ingaruka kumikorere ya kashe hamwe nubuzima bwa serivisi, kandi ntibyoroshye. kubungabunga.
7. Kugereranya imikorere yimyenda y amarembo nuburyo butandukanye
1. Ubwoko bwa wedge ubwoko bumwe bwirembo
A. Imiterere iroroshye kuruta irembo rya elastike.
B. Ku bushyuhe bwo hejuru, imikorere yo gufunga ntabwo ari nziza nkiy'irembo rya elastike cyangwa irembo rya kabiri.
C. Bikwiranye nubushyuhe bwo hejuru bworoshye kokiya.
2. Irembo rya Elastike
A. Nuburyo bwihariye bwa wedge ubwoko bumwe bwirembo valve. Ugereranije na wedge gate valve, imikorere yo gufunga ni nziza kubushyuhe bwo hejuru, kandi irembo ntabwo ryoroshye guhuzwa nyuma yo gushyuha.
B. Bikwiranye nibicuruzwa, amavuta yubushyuhe bwo hejuru hamwe nibitangazamakuru bya peteroli na gaze, hamwe nibice bihinduranya kenshi.
C. Ntibikwiriye gukoreshwa muburyo bworoshye.
3. Inzugi ebyiri z'irembo
A. Gufunga imikorere nibyiza kuruta wedge gate valve. Iyo impande zifatika zo gufunga hejuru hamwe nintebe zidahuye neza, iracyafite imikorere myiza yo gufunga.
B. Nyuma yo gufunga hejuru y irembo rimaze gushira, icyuma kiri munsi yubuso bwubuso bushobora gusimburwa no gukoreshwa nta kugaragara no gusya hejuru yikimenyetso.
C. Bikwiranye nibicuruzwa, amavuta yubushyuhe bwo hejuru hamwe nibitangazamakuru bya peteroli na gaze, hamwe nibice bihinduranya kenshi.
D. Ntibikwiriye uburyo bworoshye bwo guteka.
4. Iringaniza ry'irembo
A. Imikorere yo gushiraho ikimenyetso ni mbi kurenza ayandi marembo.
B. Bikwiranye nubushyuhe bwo hasi hamwe nubushyuhe.
C. Gutunganya no gufata neza hejuru yumuryango wintebe nintebe biroroshye kuruta ubundi bwoko bwamarembo.
8. Icyitonderwa cyo gushiraho amarembo ya Valve
1. Mbere yo kwishyiriraho, reba icyumba cya valve nubuso bwa kashe. Nta mwanda cyangwa umucanga byemewe gukurikiza.
2. Bolt muri buri gice gihuza igomba gukomera neza.
3. Kugenzura aho uwuzuza bisaba guhuzagurika, ntabwo ari ukwemeza gusa ko uwuzuza kashe, ahubwo anareba niba irembo rifungura byoroshye.
4. Mbere yo gushiraho ibyuma byububiko byibyuma, abakoresha bagomba kugenzura ubwoko bwa valve, ingano ihuza hamwe nicyerekezo cyitangazamakuru kugirango barebe ko bihuye nibisabwa na valve.
5. Mugihe ushyiraho ibyuma byububiko byibyuma, abakoresha bagomba kubika umwanya ukenewe wo gutwara valve.
6. Gukoresha ibikoresho byo gutwara bigomba gukorwa ukurikije igishushanyo mbonera.
7. Impapuro zometseho ibyuma bigomba kubungabungwa buri gihe. Nta kugongana gutunguranye no gusohora byemewe kugira ingaruka kuri kashe.
