Ugomba guhitamo umupira wumupira, ariko ibinyuranye ni byinshi. Guhitamo ubwoko butari bwo bushobora gusobanura nabi, kumeneka ejo hazaza, cyangwa sisitemu iteye ubwoba kubungabunga.

Ubwoko bune bwibanze bwimipira yashyizwe mubyiciro byubaka umubiri: igice kimwe,ibice bibiri, ibice bitatu, na hejuru-byinjira. Buri gishushanyo gitanga itandukaniro ritandukanye ryibiciro, imbaraga, nuburyo bworoshye bwo gusana, kubihuza nibisabwa byihariye no kubikenera.

Gusobanukirwa ubu bwoko bwibanze nintambwe yambere, ariko ni intangiriro. Nkunze kugira iki kiganiro na Budi, umuyobozi wingenzi wo kugura nkorana na Indoneziya. Abakiriya be bayobewe n'amagambo yose. Asanga amaze gusobanura itandukaniro ryibanze muburyo bworoshye, abakiriya be bumva bafite ikizere cyinshi. Barashobora kuva mubidashidikanywaho bagahitamo abahanga, baba bagura valve yoroshye kumurongo wo kuhira cyangwa iyindi igoye kubikorwa byinganda. Reka dusenye icyo ubu bwoko busobanura kuri wewe.

Ni ubuhe bwoko butandukanye bwimipira yumupira?

Urabona amagambo nka "icyambu cyuzuye," "trunnion," na "umupira ureremba" kumpapuro zihariye. Iyi jargon ya tekiniki ituma bigorana kumenya niba ubona imikorere ikwiye kubyo ukeneye byihariye.

Kurenga imiterere yumubiri, imipira yumupira yandikwa nubunini bwazo (icyambu cyuzuye nicyambu gisanzwe) n'umupira w'imbere imbere (kureremba na trunnion). Icyambu cyuzuye gitanga urujya n'uruza, mugihe igishushanyo cya trunnion gikemura ibibazo byinshi cyane.

Reka twibire cyane mumubiri ndetse nubwoko bwimbere. Kubaka umubiri byose ni uburyo bwo kubungabunga. A.igice kimwevalve nigice gifunze; ntibihendutse ariko ntibishobora gusanwa. A.ibice bibiriumubiri wa valve wigabanyijemo kabiri, yemerera gusana, ariko ugomba kubanza kuyikura mumuyoboro. Igishushanyo mbonera-cyiza cyane niibice bitatuindanga. Igice cyo hagati kirimo umupira kirashobora gukurwaho mugukuramo ibice bibiri, hasigara imiyoboro idahwitse. Nibyiza kumurongo ukeneye serivisi kenshi. Imbere, "icyambu" cyangwa umwobo mumupira bifite akamaro. A.icyambuvalve ifite umwobo ingana nu muyoboro, ikora imipaka ya zeru. A.icyambu gisanzweni ntoya, nibyiza kubisabwa byinshi. Kurangiza, hafi ya PVC yumupira wumupira ukoresha aumupira urerembaigishushanyo, aho sisitemu ya sisitemu isunika umupira neza imbere yintebe yo hasi kugirango ikore kashe.

Ubwoko bwa Ball Valve Ubwoko

Ni ubuhe bwoko butandukanye bwo guhuza imipira ya valve?

Wabonye valve nziza, ariko noneho ugomba kuyihuza. Guhitamo uburyo butari bwo bwo guhuza bishobora kuganisha kubintu byoroshye, kumeneka bidasubirwaho, cyangwa sisitemu udashobora gutanga udafite hackaw.

Ubwoko busanzwe bwo guhuza imipira yumupira ni solvent-weld socket kugirango uhuze PVC ihoraho, imitwe yomutwe kugirango ihuze ibikoresho bitandukanye, impande zomekeranye kumiyoboro minini, hamwe nubumwe bwukuri kugirango ubone serivisi nziza.

Ubwoko bwihuza wahisemo busobanura uburyo valve ihuza imiyoboro yawe.Sockcyangwa "kunyerera" ikoreshwa kumiyoboro ya PVC, ikora umurongo uhoraho, udashobora kumeneka ukoresheje sima ya solvent. Ibi biroroshye kandi byizewe cyane.Urudodoguhuza (NPT cyangwa BSPT) bigufasha gusunika valve kumuyoboro wogoshywe, nibyiza cyane guhuza PVC nibice byicyuma, ariko bisaba gufunga umugozi no gushiraho witonze kugirango wirinde kumeneka. Ku miyoboro minini (mubisanzwe hejuru ya santimetero 2),flangedihuriro rikoreshwa. Bakoresha bolts na gaze kugirango bakore kashe ikomeye, itekanye, kandi byoroshye gukurwaho. Ariko kugirango ibungabunge byimazeyo mumiyoboro mito, ntakintu gikubita aUbumwe nyabwoindanga. Igishushanyo gifite ibice bibiri byubumwe bikwemerera gukuraho burundu umubiri wo hagati wa valve kugirango usanwe cyangwa usimburwe mugihe iherezo ryihuza rikomeza gufatirwa kumuyoboro. Nibyiza byisi byombi: guhuza gukomeye na serivisi yoroshye.

Kugereranya Ubwoko Bwihuza

Ni ubuhe bwoko butandukanye bwa MOV?

Ushaka gukoresha sisitemu yawe, ariko "MOV" isa nkibikoresho byinganda bigoye. Ntabwo uzi neza inkomoko yimbaraga, amahitamo yo kugenzura, kandi niba ari ningirakamaro kumushinga wawe.

MOV isobanuraMoteri ikoreshwa na moteri, ni valve iyo ari yo yose igenzurwa na actuator. Ubwoko bubiri bwingenzi nuburyo bukoresha amashanyarazi, bukoresha moteri yamashanyarazi, hamwe na pneumatike ikora, ikoresha umwuka ucogora kugirango ikore valve.

MOV ntabwo ari ubwoko bwihariye bwa valve; ni valve isanzwe hamwe na actuator yashizwemo. Ubwoko bwa actuator nicyo cyingenzi.Amashanyarazinibisanzwe cyane kumipira ya PVC muri sisitemu yamazi. Bakoresha moteri ntoya kugirango bafungure valve ifunguye cyangwa ifunze kandi iraboneka mumashanyarazi atandukanye (nka 24V DC cyangwa 220V AC) kugirango bahuze inkomoko yawe. Nibyiza kubisabwa nka zone zohira zikoresha, gufata amazi, cyangwa kuzuza ikigega cya kure.Indwara ya pneumatikekoresha imbaraga zumwuka uhumeka kugirango ufate valve ifunguye cyangwa ifunze vuba cyane. Zirakomeye cyane kandi zizewe ariko zisaba compressor yo mu kirere n'imirongo yo mu kirere gukora. Mubisanzwe mubibona gusa munganda nini zinganda aho umwuka wugarijwe usanzwe uri mubikorwa remezo. Kuri benshi mubakiriya ba Budi, abakoresha amashanyarazi batanga impirimbanyi nziza yo kugenzura, igiciro, kandi byoroshye.

Ni irihe tandukaniro riri hagati yubwoko bwa 1 nubwoko bwa ball ball?

Urimo usoma urupapuro rwihariye hanyuma urebe "Andika 21 Ball Valve" kandi udafite ibimenyetso icyo bivuze. Ufite impungenge ko ushobora kubura amakuru yingenzi kubyerekeye umutekano cyangwa imikorere yayo.

Iri jambo risanzwe ryerekeza ku gisekuru cyukuri cyumupira wumupira uva mubirango byihariye. "Ubwoko bwa 21 ″ bwabaye bugufi kubushakashatsi bugezweho, bukora neza cyane burimo umutekano wingenzi hamwe nibikoreshwa nkibikoresho byangiza ubumwe.

Ijambo "Ubwoko 1 ″ cyangwa" Ubwoko 21 ″ ntabwo aribipimo rusange mubikorwa byose, ariko bivuga ibishushanyo mbonera byagize isoko. Tekereza kuri "Ubwoko bwa 21 ″ nkugereranya ibipimo bigezweho, bihebuje kuri valve yubumwe nyabwo. Mugihe twashushanyaga indangagaciro nyayo yubumwe bwa Pntek, twashizemo amahame atuma ibishushanyo byiza cyane. Ikintu cyingenzi cyane niGuhagarika-Umutekano wubumwe. Ubu ni uburyo bwumutekano aho ibinyomoro bifite urudodo rufunga, bigatuma bidashoboka guhita ucukumbura no gufungura sisitemu mugihe iri mukibazo. Ibi birinda guhungabana. Ibindi bintu bisanzwe biranga ubu buryo birimoIkibaho kabiri O-impetakurwego rwo hejuru rwo kumeneka kurutoki na anIgikoresho cyo kwishyiriraho(akenshi kuri ISO 5211 isanzwe) ituma byoroha kongeramo amashanyarazi nyuma. Ntabwo ari valve gusa; ni umutekano, wizewe, kandi uzaza-sisitemu igizwe.

Umwanzuro

Ubwoko bune nyamukuru bwa valve bwerekeza kumiterere yumubiri, ariko gusobanukirwa kwukuri guturuka kukumenya icyambu, guhuza, nuburyo bwo gukora. Ubu bumenyi butuma uhitamo valve nziza kumurimo uwo ariwo wose.
