Guhitamo umupira wumupira bisa nkibyoroshye kugeza ubonye amahitamo yose. Toranya ibitari byo, kandi ushobora guhura nogutemba kugabanijwe, kugenzura nabi, cyangwa no kunanirwa kwa sisitemu.

Ubwoko bune bwingenzi bwimipira yashyizwe mubikorwa n'imiterere yabyo: umupira wamaguru ureremba, umupira wa trunnion ushyizwemo umupira wuzuye, icyambu cyuzuye, hamwe na valve yagabanutse. Buri kimwe gikwiranye ningutu zitandukanye nibisabwa.

Nkunze kuvugana na Budi, umuyobozi ushinzwe kugura umwe mubafatanyabikorwa bacu muri Indoneziya, kubyerekeye guhugura itsinda rye ryo kugurisha. Imwe mu mbogamizi nini kubacuruzi bashya nuburyo butandukanye bwa valve. Basobanukiwe nibikorwa byibanze kuri / kuzimya, ariko noneho bakubitwa namagambo nka "trunnion^[1], ”“ L-port, ”cyangwa“kureremba^[2]. ” Umukiriya arashobora gusaba valve kumurongo wumuvuduko ukabije, kandi umucuruzi mushya ashobora gutanga valve isanzwe ireremba mugihe valve ya trunnion aricyo gikenewe rwose. Gucamo ibice ibyiciro byoroshye, byumvikana nibyingenzi. Ntabwo ari ugucuruza ibicuruzwa gusa kugirango umushinga ubashe gutsinda.

Ni ubuhe bwoko bune bw'imipira?

Ukeneye valve, ariko kataloge yerekana ubwoko bwinshi. Gukoresha nabi birashobora gukora icyuho muri sisitemu cyangwa bivuze ko wishyuye amafaranga menshi kubintu udakeneye.

Imipira yumupira akenshi ishyirwa mubikorwa byumupira wabo hamwe nubunini bwa bore. Ubwoko bune busanzwe ni: kureremba na trunnion-byashizweho (kubufasha bwumupira) hamwe na port-port hamwe no kugabanya-icyambu (nukugurura ubunini). Buriwese atanga impuzandengo itandukanye yimikorere nigiciro.

Reka tubisenye byoroshye. Ubwoko bubiri bwa mbere bujyanye nuburyo umupira ushyigikiwe imbere ya valve. A.umupira wamaguru^[3]ni Ubwoko Bisanzwe; umupira ufatirwa mumwanya wo hasi no hejuru. Nibyiza kubisanzwe bisanzwe. A.trunnion^[4]ifite ibikoresho byongera imashini - uruti hejuru na trunnion hepfo - gufata umupira. Ibi bituma biba byiza kumuvuduko mwinshi cyangwa nini cyane. Ubwoko bubiri bukurikira bujyanye nubunini bwumwobo unyuze mumupira. A.icyambu(cyangwa byuzuye-bore) valve ifite umwobo ingana nu muyoboro, bigatuma nta mbogamizi zibuza. A.Kugabanukavalve ifite umwobo muto. Nibyiza rwose mubihe byinshi kandi bituma valve iba nto kandi ihendutse.

Kugereranya Ubwoko Bune Bukuru

Nigute ushobora kumenya niba umupira wumupira ufunguye cyangwa ufunze?

Ugiye guca mu muyoboro, ariko uzi neza ko valve ifunze? Ikosa ryoroshye hano rirashobora gukurura akajagari gakomeye, kwangirika kwamazi, cyangwa no gukomeretsa.

Urashobora kumenya niba aumupira wamaguruirakinguye cyangwa ifunze urebye aho ikiganza gihagaze ugereranije n'umuyoboro. Niba ikiganza kibangikanye n'umuyoboro, valve irakinguye. Niba ikiganza ari perpendicular (gukora ishusho ya “T”), valve ifunze.

Iki nigice cyibanze kandi cyingenzi cyubumenyi kubantu bose bakorana numupira wumupira. Umwanya wikiganza ni icyerekezo cyerekana neza umupira. Ubu buryo bworoshye bwo gushushanya nimwe mumpamvu nyamukuru imipira yumupira ikunzwe cyane. Nta gushidikanya. Nigeze kumva inkuru ivuye i Budi ivuga ku mukozi muto wo kubungabunga ikigo cyihuta. Yitegereje kuri valve atekereza ko yazimye, ariko ni irembo rya kera ryakera ryasabaga impinduka nyinshi, kandi ntashobora kumenya uko rihagaze. Yakoze gutema maze yuzura icyumba. Numupira wumupira, iryo kosa ntirishoboka gukora. Igihembwe-cyerekezo cyibikorwa hamwe numwanya usobanutse utanga ibitekerezo byihuse, bidasobanutse: kumurongo ni "kuri," hakurya ni "kuzimya." Iyi ngingo yoroshye nigikoresho gikomeye cyumutekano.

Ni irihe tandukaniro riri hagati yubwoko bwa T na L imipira yumupira?

Ugomba kuyobya imigezi, ntuyihagarike gusa. Gutumiza valve isanzwe ntabwo bizakora, kandi gutumiza indege itari nziza irashobora kohereza amazi ahantu habi rwose.

T-ubwoko na L-ubwoko bwerekana imiterere ya bore mumupira wa valve-3. Ubwoko bwa L burashobora gutandukanya imigezi kuva kumurongo umwe ujya murimwe. Ubwoko bwa T burashobora gukora kimwe, wongeyeho burashobora guhuza ibyambu uko ari bitatu hamwe.

Nibintu bisanzwe bitera urujijo kubantu bagura valve yabo ya mbere yinzira 3. Reka dutekereze kuri valve ifite ibyambu bitatu: hepfo, ibumoso, niburyo. AnL-Icyambu^[5]valve ifite dogere 90 igoramye ikoresheje umupira. Umwanya umwe, uhuza icyambu cyo hepfo nicyambu cyibumoso. Hamwe na kimwe cya kane, ihuza icyambu cyo hepfo nicyambu cyiburyo. Ntishobora guhuza ibyo uko ari bitatu. Nibyiza byo gutembera gutemba kuva isoko imwe kugera kubintu bibiri bitandukanye. A.T-Port^[6]valve ifite ishusho ya "T" yacukuwe mumupira. Ifite amahitamo menshi. Irashobora guhuza epfo ibumoso, hepfo iburyo, cyangwa irashobora guhuza ibumoso iburyo (kurenga hepfo). Byibanze, ifite kandi umwanya uhuza ibyambu uko ari bitatu icyarimwe, byemerera kuvanga cyangwa gutandukana. Ikipe ya Budi ihora ibaza umukiriya: “Ukeneye kuvanga imigezi, cyangwa guhinduranya hagati yabo?” Igisubizo gihita kibabwira niba hakenewe T-Port cyangwa L-Port.

L-Port na T-Port Ubushobozi

Ni irihe tandukaniro riri hagati ya trunnion na ball ball ireremba?

Sisitemu yawe ikora munsi yumuvuduko mwinshi. Niba uhisemo umupira usanzwe, igitutu kirashobora kugorana guhinduka cyangwa no gutera kashe kunanirwa mugihe.

Muri valve ireremba, umupira "ureremba" hagati yintebe, usunitswe nigitutu. Muri valve ya trunnion, umupira uhambirizwa mumashanyarazi hejuru no hepfo (trunnion), ikurura umuvuduko kandi igabanya imihangayiko kumyanya.

Itandukaniro ni byose bijyanye no gucunga imbaraga. Mubisanzweumupira wamaguru^[7], iyo valve ifunze, umuvuduko wo hejuru usunika umupira cyane kuntebe yo hasi. Izo mbaraga zikora kashe. Mugihe bigira akamaro, ibi nabyo bitera guterana amagambo menshi, bishobora gutuma valve igora guhinduka cyane cyane mubunini bunini cyangwa munsi yumuvuduko mwinshi. A.trunnion^[8]gikemura iki kibazo. Umupira ushyizwe mumwanya na trunnion ushyigikiwe, ntabwo rero usunikwa numugezi. Umuvuduko ahubwo usunika intebe zuzuye amasoko kumupira uhagaze. Igishushanyo gikurura imbaraga zidasanzwe, bikavamo urumuri rwo hasi cyane (biroroshye guhinduka) hamwe nubuzima burebure. Niyo mpanvu kubikorwa byinganda zikoreshwa cyane, cyane cyane munganda za peteroli na gaze, trunnion valve nibisabwa. Kuri sisitemu nyinshi za PVC, imikazo ni mike bihagije kuburyo valve ireremba ikora neza.

Kureremba na Trunnion Umutwe-ku-mutwe

Umwanzuro

Ubwoko bune bwingenzi bwa valve - kureremba, trunnion, icyambu-cyuzuye, hamwe no kugabanya-icyambu - bitanga amahitamo kubisabwa byose. Kumenya itandukaniro riri hagati yabo, nubwoko bwihariye nka L-port na T-port, byemeza ko wahisemo neza.
