I-valve yebhabhathane

I-valve yebhabhathane ingeyesigaba se-valve yekota. Ama-valve ekota afaka izinhlobo zama-valve ezingavulwa noma zivalwe ngokuphendula isiqu ikota.amavalvu ebhabhathane, kukhona idiski enamathiselwe esiqwini. Uma induku ijikeleza, ijikeleza idiski ngekota, okwenza idiski iwele iqonde ngqo oketshezini futhi iyeke ukugeleza. Ukuze kubuyiselwe ukugeleza, isiqu sijikeleza idiski sibuyele endaweni yaso yokuqala, kude nokugeleza.

Amavalvu e-Butterfly ayisinqumo esithandwayo ngoba kulula ukuwafaka, ashibhile, futhi atholakala cishe kuwo wonke amasayizi. Lawa avame ukusetshenziselwa izinsizakalo zokulawula kanye nezinjongo zokushintsha.

Isicelo se-Butterfly Valve

Amavalvu e-butterfly abalulekile ezinqubweni nasekusebenzeni ezimbonini eziningi ezahlukene. Lokhu kungenxa yobubanzi bawo kanye nekhono lokulawula ukugeleza koketshezi, igesi kanye nodaka. Amavalvu e-butterfly awakwazi nje kuphela ukumisa noma ukuqala ukugeleza, kodwa futhi angakwazi ukukhawulela noma ukunciphisa ukugeleza njengoba kudingeka lapho evulwa kancane.

Amakhasimende avela ezimbonini eziningi athenga ama-butterfly valve, okuhlanganisa nalawo asemikhakheni yokucubungula ukudla (uketshezi), izitshalo zamanzi, ukunisela, ukukhiqizwa kwamapayipi, ukukhiqizwa kwezimboni, izinhlelo zokushisa kanye nokuthuthwa kwamakhemikhali.

Nakuba ama-valve e-butterfly enezinhlelo zokusebenza eziningi ezahlukene, ezinye izinhlelo zokusebenza ezithile zifaka phakathi i-vacuum, ukubuyisa uwoyela, isevisi yomoya ocindezelwe, ukupholisa umoya namanzi, i-HVAC, isevisi yodaka, isevisi yamanzi anomfutho ophezulu, isevisi yamanzi anokushisa okuphezulu, isevisi yomusi kanye nokuvikelwa komlilo.

Ngenxa yokwahlukahluka komklamo nezinto zokwakha, ama-valve e-butterfly anezinhlelo zokusebenza eziningi. Lawa angafakwa kunoma yiliphi ipayipi, kusukela emanzini ahlanzekile kuya koketshezi lokugaya noma i-slurry. Lawa avame ukusetshenziswa ezinhlelweni zodaka noma i-sludge, izinsizakalo ze-vacuum, izinsizakalo zomusi, amanzi okupholisa, umoya, noma igesi.

Izinzuzo kanye nokungalungi kwe-butterfly valve

Amavalvu ebhabhathaneinikeza abasebenzisi izinzuzo eziningi. Okokuqala, banomklamo omncane. Ngenxa yalo mklamo omncane, badinga indawo yokusebenza encane kunezinye izivalo eziningi. Okwesibili, izindleko zokulungisa izivalo zezivalo ziphansi impela. Okwesibili, zihlinzeka ngokuminyana kwezimoto ezisezingeni eliphezulu. Futhi, azivuzi, kodwa zingavulwa kalula uma kudingeka. Enye inzuzo yezivalo zezivalo izivalo intengo yazo ephansi.

Izinzuzo ze-butterfly valve

1. Ngenxa yobukhulu bazo obuncane kanye nomklamo omncane, izindleko zokufaka ziphansi kakhulu.

2. Lawa ma-valve athatha isikhala esincane kakhulu uma kuqhathaniswa namanye ama-valve.

3. Ukusebenza okuzenzakalelayo kwenza kube lula futhi kusebenze kangcono kunezinye izivalo.

4. Ngenxa yokwakheka kwama-disc amaningi kanye nezingxenye ezimbalwa ezihambayo, idinga ukulungiswa okuncane, ngaleyo ndlela kunciphisa kakhulu ukuguquguquka kwesimo sezulu.

5. Izinto ezahlukene zesihlalo zenza kube lula ukuzisebenzisa kuzo zonke izinhlobo zezindawo, ngisho nasezindaweni ezihlukumezayo.

6. Amavalvu ebhabhathane adinga izinto ezincane, kulula ukuwaklama nokuwakhiqiza, futhi ngokuvamile ashibhile kakhulu kunezinye izinhlobo zamavalvu.

7. Amavalvu e-Butterfly angasetshenziswa ezinhlotsheni ezahlukene zokusebenza, okuhlanganisa nokufakwa ngaphansi komhlaba.

Izinkinga ze-butterfly valve

Ngempela, izinkinga zamavalvu e-butterfly zidlula izinzuzo. Kodwa ngaphambi kokusebenzisa lawa mavalvu, kusenezinto okufanele uzikhumbule.

1. Ngisho noma ivuliwe ngokuphelele, indawo encane yediski izovimbela ukugeleza kwezinto. Lokhu kungathinta ukunyakaza kwendawo yediski kanye nokushintsha kokucindezela epayipini.

2. Umsebenzi wokuvala awumuhle njengamanye ama-valve.

3. I-throttling isebenza kuphela kwinsizakalo yokucindezela okuphansi.

4. Ivalvu yebhabhathane ihlala inengozi yokuvimba ukugeleza noma ukuvuvukala kwemithambo yegazi.

Isakhiwo sevalvu yebhabhathane

Amavalvu e-Butterfly anezici eziningana eziyinhloko. Lokhu kufaka phakathi umzimba, idiski, isiqu, kanye nesihlalo. Ane-actuator, njenge-lever. Umqhubi angajikelezisa i-actuator ye-valve ukushintsha isikhundla sediski.

Umzimba wevalvu ufakwe phakathi kwama-flange amabili epayipi. Okuvame kakhulu kuzo zonke izinhlobo zomzimba yizicucu nama-disc.

Umgomo wokusebenza wediski yevalvu ufana nesango elisevalvini yesango, ipulaki evalvini yepulaki, nebhola eliseivalvu yebhola, njll. Uma ijikeleziswa ngo-90 ° ukuze igeleze ngokuhambisana noketshezi, idiski isendaweni evulekile. Kulesi simo, idiski izovumela lonke uketshezi ukuthi ludlule. Uma idiski ijikeleza futhi, idiski ingena endaweni evaliwe futhi ivimbele ukugeleza koketshezi. Kuye ngokuma kwediski kanye nomklamo, umenzi angakwazi ukulawula i-torque yokusebenza, ukuvala kanye/noma ukugeleza.

Isiqu sevalvu siwumshafti. Singaba yingcezu eyodwa noma ezimbili. Uma kuyisiqeshana sokugcina, sibizwa ngokuthi isiqu esihlukanisiwe.

Isihlalo sixhunywe emzimbeni wemoto ngokucindezela, ukubopha noma ukukhiya. Umenzi uvame ukwenza isihlalo se-valve nge-polymer noma i-elastomer. Inhloso yesihlalo se-valve ukunikeza umsebenzi wokuvala i-valve. Yingakho amandla ajikelezayo adingekayo ekuvaleni i-valve ye-butterfly ebizwa ngokuthi “i-seat torque”, kanti amandla ajikelezayo adingekayo e-butterfly valve ukuze ajikeleze into yayo yokuvala ebizwa ngokuthi “i-off seat torque”.

I-actuator ingaba ngeyomshini noma ezenzakalelayo, futhi ukugeleza ngepayipi kungalungiswa ngokuhambisa idiski yevalvu. Uma ivaliwe, idiski yevalvu imboza imbobo yevalvu, futhi uketshezi luhlala luthinta idiski yevalvu. Lokhu kuzobangela ukwehla kwengcindezi. Ukuze ushintshe indawo yediski ukuze inikeze indlela ukugeleza koketshezi, phendula isiqu ngokujika kwekota.
