Imipira yumupirabifite inzego nyinshi, ariko mubyukuri birasa. Ibice byo gufungura no gufunga ni uruziga ruzengurutse, rugizwe ahanini nintebe za valve, imipira, impeta zifunga, ibiti bya valve nibindi bikoresho bikora. Igiti cya valve kizunguruka dogere 90 kugirango ugere ku gufungura no gufunga indangagaciro. Imipira yumupira ikoreshwa kumiyoboro yo kuzimya, gukwirakwiza, kugenga imigendekere no guhindura icyerekezo cyo hagati. Intebe ya valve ikoresha uburyo butandukanye bwo gufunga intebe ukurikije imikorere itandukanye. Umubiri wumupira wa O wo mu bwoko bwa O ufite umupira ufite hagati unyuze mu mwobo ufite diameter ingana na diameter ya pipe. Umupira urashobora kuzunguruka mucyicaro. Hariho impeta ya buri mwaka ya elastike kumpande zombi mu cyerekezo cyumuyoboro. V-imipira yumupira V ifite imiterere ya V. Intanga ya valve nigice cya 1/4 cyikigina hamwe na V. Ifite ubushobozi bunini bwo gutembera, intera nini ishobora guhinduka, imbaraga zo kogosha, kandi irashobora gufungwa cyane. Irakwiriye cyane cyane mubihe byamazi aho ibikoresho biri hamwe na fibrous.
1. O-umupira wumupira wa valve:
Ubwoko bwa O-ball ball igenzura icyerekezo giciriritse y yizunguruka umupira 90 °, nkigisubizo, unyuze mu mwobo urashobora guhinduka, bityo ukamenya gufungura no gufunga umupira wumupira. O-ubwoko bwumupira wa valve ifata igishushanyo kireremba cyangwa gihamye. Ibice byimuka bigereranijwe bikozwe mubikoresho byo kwisiga hamwe na coefficient ntoya cyane yo guterana, bityo torque ikora ni nto. Byongeye kandi, gufunga igihe kirekire cyo gufunga amavuta bituma imikorere irushaho guhinduka. Ibyiza byibicuruzwa nibi bikurikira:
-
O-ubwoko bwumupira wumupira ufite imbaraga zo kurwanya amazi
Imipira yumupira muri rusange ifite ibice bibiri: diameter yuzuye no kugabanya diameter. Ntakibazo cyaba kimeze gute, coeffisente yo kurwanya umuvuduko wumupira wumupira ni muto. Imipira isanzwe yumupira irigororotse, izwi kandi nkumupira wuzuye wuzuye. Umuyoboro wa diameter uhwanye na diametre y'imbere y'umuyoboro, kandi igihombo cyo kurwanya ni uguhangana gusa n'uburebure bumwe. Uyu mupira wumupira ufite byibura amazi arwanya valve zose. Hariho uburyo bubiri bwo kugabanya ubukana bwa sisitemu yo kuvoma: imwe ni ukugabanya umuvuduko wamazi wongera diameter ya pipe na diameter ya valve, bizamura cyane ikiguzi cya sisitemu. Iya kabiri ni ukugabanya ubukana bwibanze bwa valve, kandi imipira yumupira niyo ihitamo ryiza.
-
O-ubwoko bwumupira wa valve uhinduka vuba kandi byoroshye
Umupira wumupira ukeneye gusa kuzenguruka dogere 90 kugirango ufungure neza cyangwa ufunge byuzuye, kuburyo ushobora gufungura no gufunga byihuse.
- O-ubwoko bwumupira wa valve ufite imikorere myiza yo gufunga
Imyanya myinshi yimyanya yumupira ikozwe mubikoresho byoroshye nka PTFE, bikunze kwitwa imipira yoroheje-ifunga imipira. Umupira woroshye wo gufunga imipira ifite imikorere myiza yo gufunga kandi ntisaba uburakari bukabije hamwe nuburyo bwo gutunganya neza neza neza.
-
O-ubwoko bwumupira wa valve ufite ubuzima burebure
Kuberako PTFE / F4 ifite ibintu byiza byo kwisiga, coefficient de coiffure hamwe n'umuzingi ni nto. Bitewe nubuhanga bunoze bwo gutunganya, ubukana bwumupira buragabanuka, bityo byongera cyane ubuzima bwa serivisi ya valve yumupira.
-
O-ubwoko bwumupira wa valve ufite ubwizerwe buhanitse
Gufunga umupira hamwe nintebe ya valve ntabwo bizababazwa no gushushanya, kwambara byihuse nandi makosa;
Nyuma yuko igiti cya valve gihinduwe muburyo bwubatswe, ibyago byimpanuka yuko igiti cya valve gishobora kuguruka bitewe no kugabanuka kwa glande yapakiwe nigikorwa cyumuvuduko wamazi wavanyweho;
Imipira yumupira ifite anti-static kandi irwanya umuriro irashobora gukoreshwa mumiyoboro itwara peteroli, gaze gasanzwe, na gaze yamakara.
Umuyoboro wa valve (umupira) wa O-umupira wumupira wa siporo. Urebye muburyo bw'imiterere, intebe yumupira yashyizwe mucyicaro kuruhande rwumubiri wa valve mugihe gifunze. Ibice byimuka bigereranijwe bikozwe mubikoresho byo kwisiga hamwe na coefficient ntoya cyane yo guterana, bityo torque ikora ni nto. Byongeye kandi, gufunga igihe kirekire cyo gufunga amavuta bituma imikorere irushaho guhinduka. Mubisanzwe bikoreshwa muburyo bubiri bwo guhindura, ibiranga urujya n'uruza byihuse.
Iyo umupira wo mu bwoko bwa O ufunguye neza, impande zombi ntizibujijwe, zikora umuyoboro ugororotse ufite kashe ebyiri. Ifite imikorere "yo kwisukura" nziza kandi irakwiriye mugihe cyo guca imyanya ibiri yibitangazamakuru byanduye kandi birimo fibre. Umupira wumupira uhora utera guterana hamwe na valve mugihe cyo gufungura no gufunga inzira ya valve. Muri icyo gihe, ikidodo kiri hagati yimikorere ya valve nicyicaro cya valve kigerwaho nimbaraga zo kubanza gufunga intebe ya valve ikanda kumupira. Ariko, kubera icyicaro cyoroshye cyo gufunga icyicaro, Ibikoresho byiza bya mehaniki na physique bituma imikorere yayo ifunga neza cyane.
2.Imiterere ya V ifite imipira ya valve:
Umupira wumupira wumupira wa V umeze nka V ufite imiterere ya V. Intanga ya valve nigice cya 1/4 cyikigina hamwe na V. Ifite ubushobozi bunini bwo gutembera, intera nini ishobora guhinduka, imbaraga zo kogosha, kandi irashobora gufungwa cyane. Irakwiriye cyane cyane kumazi. Imiterere aho ibikoresho ari fibrous. Mubisanzwe, imipira yumupira V ifite imipira imwe. Ntibikwiriye gukoreshwa muburyo bubiri.
Hariho ubwoko 4 bwubwoko bwa V, dogere 15, dogere 30, dogere 60, dogere 90.
Impera ya V igabanya umwanda. Mugihe cyo kuzunguruka kumupira, icyuma cya V kimeze nkicyuma cyumupira gihuza intebe ya valve, bityo ugaca fibre nibintu bikomeye mumazi. Nyamara, imipira isanzwe yumupira ntabwo ifite iyi mikorere, biroroshye rero gutera umwanda wa fibre gukomera mugihe ufunze, bigatera kubungabunga no gusana ibibazo. Kubungabunga ni ibintu bitoroshye. Intanga ya valve ya V ifite imipira ya V ntishobora gukomera na fibre. Mubyongeyeho, kubera guhuza flange, biroroshye gusenya no guterana nta bikoresho byihariye, kandi kubungabunga nabyo biroroshye. iyo valve ifunze. Hariho imikasi imeze nk'umugozi hagati ya V-shusho ya V n'intebe ya valve, idafite ibikorwa byo kwisukura gusa ahubwo inabuza umupira wumupira gukomera. Umubiri wa valve, igipfundikizo cya valve hamwe nintebe ya valve bifata ibyuma byerekanwe kumurongo, hamwe na coefficient ntoya yo guterana. Igiti cya valve cyuzuye amasoko, nuko torque ikora ni nto kandi ihamye cyane.
V-shusho yumupira wumurongo ni iburyo-buringaniye buzenguruka bushobora kugera kumikorere. Irashobora kugera ku ntera zitandukanye ukurikije igipimo cya V kimeze nkumupira wa V. Imipira ya V ifite ishusho ya V ikoreshwa mubusanzwe ifatanije na valve ikora hamwe na posisiyo kugirango igere ku ihinduka. , V-shusho ya valve yibanze irakwiriye cyane mubihe bitandukanye byo guhinduka. Ifite coefficient nini yagabanijwe, igipimo kinini gishobora guhindurwa, ingaruka nziza yo gufunga, zero sensibilité mubikorwa byo guhindura, ingano nto, kandi irashobora gushyirwaho uhagaritse cyangwa utambitse. Birakwiye kugenzura gaze, amavuta, amazi nibindi bitangazamakuru. Imipira ya V ifite ishusho ya V nuburyo bugororotse buringaniye, bugizwe numubiri wa V umeze nka V, pneumatic actuator, posisiyo hamwe nibindi bikoresho; ifite imigendekere yihariye iranga igereranyo kingana; ifata ibyiciro bibiri, ifite itangiriro rito, kandi ifite Sensitivite nziza kandi yihuta, ubushobozi bwo gukata cyane.
