Igihe kirekire cyo kubungabunga no guteranya ibisabwa kuri valve
Coefficient ya valve resistance biterwa nubunini, imiterere nuburyo bwimiterere yibicuruzwa bya valve. Buri kintu cyose kiri mumyanya yumubiri wa valve gishobora gutekerezwa nka sisitemu yibice bitanga imbaraga (guhinduka amazi, kwaguka, amasezerano, guhindukira byongeye, nibindi). Kubwibyo, gutakaza umuvuduko muri valve hafi yingana nigiteranyo cyo gutakaza umuvuduko wa buri kintu kigize valve. Twakagombye kwerekana ko ihinduka ryokurwanya ikintu kimwe muri sisitemu bizatera impinduka cyangwa isaranganya ryurwanya muri sisitemu yose, ni ukuvuga ko urujya n'uruza rugira ingaruka kuri buri gice cyumuyoboro.
Iyo amazi anyuze muri valve, igihombo cyayo cyo kurwanya amazi kigaragazwa nigabanuka ryumuvuduko wamazi ¡÷ P mbere na nyuma ya valve.
Kubisukari byuzuye:
Aho ¡÷ P - gutakaza umuvuduko wa valve munsi yikizamini (MPa)
¦Æ - coefficient de coiffe ya flux;
P - Ubucucike bwamazi (kg / mm)
U - Impuzandengo yumuvuduko wamazi mumazi (mm / s)
Amazi arwanya ibice bya valve
Coefficient ya valve resistance biterwa nubunini, imiterere nuburyo bwimiterere yibicuruzwa bya valve. Buri kintu cyose kiri mumyanya yumubiri wa valve gishobora gutekerezwa nka sisitemu yibice bitanga imbaraga (guhinduka amazi, kwaguka, amasezerano, guhindukira byongeye, nibindi). Gutakaza umuvuduko rero muri valve bingana hafi nigiteranyo cyo gutakaza umuvuduko wa buri kintu kigize valve, ni:
Muri formula, coefficient de coiffe yibice bya valve hamwe nigipimo giciriritse kiringaniye mumuyoboro.
Twakagombye kwerekana ko impinduka mukurwanya ikintu kimwe muri sisitemu itera impinduka cyangwa isaranganya ryurwanya muri sisitemu yose, ni ukuvuga ko urujya n'uruza rugira ingaruka kuri buri gice cyumuyoboro. Kugirango dusuzume ingaruka yibice bitandukanye kubirwanya valve, hakoreshwa amakuru yo kurwanya ibintu bimwe na bimwe bisanzwe bya valve. Aya makuru yerekana isano iri hagati yimiterere nubunini bwibigize valve no kurwanya amazi.

Nkuko bigaragara ku gishushanyo 1-12, kwaguka gutunguranye bitera igihombo kinini. Kuri ubu, igice cyumuvuduko wamazi gikoreshwa mugukora eddy, guhagarika amazi no gushyushya. Isano igereranijwe hagati ya coefficient yo kurwanya kwabaturage nigipimo cyakarere kambukiranya A1 mbere yo kwaguka na A2 nyuma yo kwaguka bishobora kugaragazwa nuburinganire (1-9) na (1-10).

Igihe kirekire cyo kubungabunga no guteranya ibisabwa kuri valve
Valve nigice cyo kugenzura sisitemu yo gutanga amazi, hamwe no guhagarikwa, guhinduranya, gutandukana, gukumira impanuka, kugenzura umuvuduko, guhagarika cyangwa kugabanuka k'umuvuduko ukabije nibindi bikorwa. Imyanya ya sisitemu yo kugenzura amazi, uhereye kubintu byoroheje byisi byisi kugeza kuri sisitemu igoye cyane yo kugenzura ikoreshwa muburyo butandukanye bwa valve nibisobanuro. Imyanda irashobora gukoreshwa mugucunga imigendekere yumwuka, amazi, ibyuka, itangazamakuru ryangirika, icyondo, amavuta, ibyuma byamazi nibitangazamakuru bya radio hamwe nubundi bwoko bwamazi. Noneho, mugihe kirekire cyo gukoresha inzira ya valve igomba kuba uburyo bwo kubungabunga?
1. Ntugakoreshe ibizunguruka birebire cyangwa ibiziga bya wrench mugihe ufunze cyangwa ufungura valve.
2. Urudodo rwibiti akenshi rushyutswe hamwe nutubuto twibiti, bigomba kuba mumurongo kugirango ugumane amavuta runaka, amavuta, kugirango wizere ko urujya n'uruza rwibiti, byoroshye kandi byiza. Valve yohereza imashini, mugihe gikwiye kuri gearbox, kugirango wirinde kuruma.
3. Fungura valve umwanya muremure, hejuru yikimenyetso gishobora kuba gifatanye numwanda; Iyo ufunze, valve irashobora gufungwa buhoro buhoro, hanyuma igakingura gato, kugirango umwanda ushobora gukaraba nu muvuduko mwinshi wo hagati, hanyuma ukongera ugafunga.
4. Umuyoboro washyizwe hanze ugomba gukingirwa nintoki zirinda uruti rwa valve kugirango wirinde imvura, shelegi, umukungugu ningese
5. Umuyoboro ugomba gusukurwa no kugenzurwa kenshi kugirango ibice bya valve bisukure kandi byuzuye. Ntugashyire ibintu biremereye kuri valve kandi ntuhagarare kuri valve.
6. Mbere yo gufungura icyuka cya parike, kura amazi ahurira muri sisitemu, hanyuma ufungure buhoro buhoro kugirango wirinde ingaruka zamazi ya soda; Iyo valve ifunguye byuzuye, hindura intoki inyuma gato.
7. Umuyoboro w’ibikoresho ugomba gushyirwa ahantu humye mu nzu, kandi intera igomba gufungwa ku kibaho cy’ibishashara cyangwa gucomeka kugirango wirinde kwinjira.
Valve ibisabwa
Ibice bisukuye bigomba gufungwa kugirango bishyirwemo. Ibisabwa mubikorwa byo kwishyiriraho nibi bikurikira:
1. Amahugurwa yo kwishyiriraho agomba kuba afite isuku, cyangwa agashyiraho ahantu hasukuye by'agateganyo, nk'imyenda mishya yaguzwe cyangwa imyenda ya pulasitike, kugirango wirinde ivumbi kwinjira mugihe cyo kuyishyiraho.
2, abakozi b'iteraniro bagomba kwambara imyenda y'akazi isukuye, kwambara ipamba isukuye, umusatsi ntushobora kumeneka, ibirenge bambara inkweto zisukuye, amaboko yambara uturindantoki twa plastike, gutesha agaciro,.
3. Ibikoresho byo guterana bigomba guteshwa agaciro no gusukurwa mbere yinteko kugirango isuku ibe.
