Vavu yoyang'ana gulugufe

Vavu yoyang'ana gulugufeamatanthauza valavu yomwe imatsegula ndi kutseka diskiyo malingana ndi kutuluka kwa sing'anga yokha, ndipo imagwiritsidwa ntchito kuteteza sing'angayo kuti isabwererenso.Imatchedwanso valavu yoyendera, valavu yanjira imodzi, valavu yobwerera kumbuyo, ndi valavu yakumbuyo.Valve yowunikira ndi mtundu wa valve yodziwikiratu, ntchito yake yayikulu ndikuletsa kutuluka kwapakati kwa sing'anga, kuteteza mpope ndi mota yoyendetsa kuti zisabwerere, komanso kutulutsa kwapakati pa chidebe.Ma valve owunika amathanso kugwiritsidwa ntchito popereka mapaipi a machitidwe othandizira pomwe kupanikizika kumatha kukwera pamwamba pa kuthamanga kwa dongosolo.Ma valve owunikira amatha kugawidwa m'mabwalo oyendera (ozungulira molingana ndi pakati pa mphamvu yokoka), kukweza ma valavu (akuyenda motsatira axis), ndi ma valve owunika agulugufe (akuzungulira pakati).

Ntchito
 
Ntchito ya valve yoyang'ana gulugufe ndikungolola sing'anga kuyenda mbali imodzi ndikuletsa kuyenda mbali imodzi.Nthawi zambiri valavu yamtunduwu imagwira ntchito yokha.Pansi pa mphamvu yamadzimadzi yomwe ikuyenda mbali imodzi, valavu ya valve imatsegulidwa;pamene madzi amadzimadzi akuyenda mosiyana, kuthamanga kwamadzimadzi ndi kudzidzidzimutsa kwa valavu ya valve kumachita pampando wa valve, motero kumadula kutuluka.
 
Zomangamanga
 
Ma valve a gulugufe amaphatikiza ma valve oyendera ndi ma valve okweza.Valavu yoyang'ana swing ili ndi makina a hinge ndi diski ya valve ngati chitseko chomwe chimakhazikika momasuka pampando wokhazikika wa valve.Pofuna kuonetsetsa kuti phokoso la valve likhoza kufika pamalo oyenera a mpando wa valavu nthawi zonse, valve clack imapangidwa mu hinge mechanism kuti valve clack ikhale ndi malo okwanira kuti atembenuke ndipo imapangitsa kuti valavu ikhale yolimba komanso yogwirizana ndi mpando wa valve.Chovala cha valve chikhoza kupangidwa ndi chitsulo, chikopa, mphira, kapena chophimba chopangira chikhoza kuikidwa pazitsulo, malingana ndi zofunikira za ntchito.Pamene swing check valve yatsegulidwa kwathunthu, kuthamanga kwamadzimadzi kumakhala kosalekeza, kotero kuti kuthamanga kutsika kudzera mu valve kumakhala kochepa.Disiki ya valve ya valve yokweza valavu imakhala pamtunda wosindikizira wa mpando wa valve pa thupi la valve.Pokhapokha kuti diski ikhoza kukwezedwa ndikutsitsa momasuka, valavu yotsalayo ili ngati valve yotseka.Kuthamanga kwamadzimadzi kumakweza diski kuchokera pamalo osindikizira mpando, ndipo kubwerera kumbuyo kwa sing'anga kumapangitsa kuti diski igwerenso pampando ndikudula kutuluka.Malinga ndi momwe amagwiritsidwira ntchito, valavu ya valve imatha kukhala zitsulo zonse, kapena ikhoza kukhala ngati mphira ya rabara kapena mphete ya mphira yomwe imayikidwa pa valve clack frame.Mofanana ndi valavu yotseka, njira yamadzimadzi kudzera mu valavu yowunikira imakhalanso yopapatiza, kotero kuti kuthamanga kutsika kupyolera mu valavu yowunikira ndi yaikulu kuposa ya valavu ya swing check valve, ndipo kuthamanga kwa valve check check valve kumachepetsedwa. kawirikawiri.Vavu yamtunduwu nthawi zambiri iyenera kuyikidwa mopingasa mu payipi.
 
Malinga ndi kapangidwe kake ndi njira yoyika, valavu yoyang'anira ingagawidwe kukhala:
1. Disiki ya valavu yoyang'ana gulugufe imakhala yofanana ndi diski, ndipo imazungulira kuzungulira tsinde la mpando wa valve.Chifukwa njira yamkati ya valavu imakhala yowongoka, kukana kwa kayendedwe kake kumakhala kochepa kusiyana ndi valavu yowunikira gulugufe.Ndiwoyenera kutsika kochepa komanso osabwerera.Nthawi zazikuluzikulu zokhala ndi zosintha pafupipafupi, koma zosagwirizana ndi kutulutsa kwamphamvu, komanso kusindikiza kwake sikuli bwino ngati mtundu wonyamulira.Vavu yoyang'ana gulugufe imagawidwa m'mitundu itatu: valavu imodzi, valavu iwiri ndi valavu yambiri.Mitundu itatuyi imagawidwa makamaka molingana ndi m'mimba mwake ya valve.Cholinga chake ndikuletsa sing'anga kuti isayime kapena kuyenderera chammbuyo ndikufooketsa ma hydraulic shock.
2. Valavu yoyang'ana gulugufe: Malinga ndi mawonekedwe a diski, imagawidwa m'mitundu iwiri: 1. Valovu yoyang'ana yokhala ndi diski yothamanga pakatikati pakatikati pa thupi la valve.Vavu yoyang'ana gulugufe imatha kukhazikitsidwa paipi yopingasa.Mpira wozungulira ukhoza kugwiritsidwa ntchito pa diski ya valve yaing'ono-diameter check valve.Maonekedwe a valavu ya butterfly check valve ndi ofanana ndi valavu ya globe (yomwe ingagwiritsidwe ntchito mofanana ndi valavu ya globe), kotero kuti mphamvu yake yokana madzimadzi imakhala yaikulu.Mapangidwe ake ndi ofanana ndi valve yoyimitsa, ndipo thupi la valve ndi disc ndilofanana ndi valve yoyimitsa.Kumtunda kwa diski ya valve ndi kumunsi kwa chivundikiro cha valve kumakonzedwa ndi manja otsogolera.Chiwongolero cha disc chikhoza kusunthira mmwamba ndi pansi momasuka mu manja otsogolera ma valve.Pamene sing'anga imayenda kunsi kwa mtsinje, chimbale chimatsegula ndi kukankhira kwa sing'anga.Imagwera pampando wa vavu kuti ateteze sing'anga kubwerera kumbuyo.Mayendedwe apakati polowera ndi njira zotulutsira zowongoka zowongoka za butterfly ndi perpendicular kumayendedwe a mpando wa valve;valavu yoyang'ana yowongoka imakhala ndi njira yofanana ndi njira yolowera ndi yotuluka ngati njira ya mpando wa valve, ndipo kukana kwake kothamanga kumakhala kochepa kusiyana ndi mtundu wowongoka;2. Valovu yoyang'ana momwe diski imazungulira mozungulira pini pampando wa valve.Vavu yoyang'ana gulugufe ili ndi mawonekedwe osavuta ndipo imatha kukhazikitsidwa paipi yopingasa, osasindikiza bwino.
3. Vavu yoyang'ana pamzere: valavu yomwe chimbale chake chimayenda pakatikati pa thupi la valve.Vavu yoyang'ana pamzere ndi mtundu watsopano wa valve.Ndi yaying'ono kukula kwake, yopepuka kulemera, komanso yabwino pakukonza ukadaulo.Ndi imodzi mwa njira zachitukuko za ma valve cheke.Koma coefficient ya kukana kwamadzimadzi ndi yayikulu pang'ono kuposa ya swing check valve.
4. Valavu yowunikira: Vavu iyi imagwiritsidwa ntchito ngati madzi ophikira ndi madzi otsekera.Ili ndi ntchito yokwanira ya valavu yokweza ndi valavu yoyimitsa kapena valavu.
Kuonjezera apo, pali ma valavu owunika omwe sali oyenerera kuyika pampu, monga ma valve a phazi, masika, mtundu wa Y ndi ma valve ena.

Kagwiritsidwe ndi kagwiritsidwe ntchito:
Valve iyi imagwiritsidwa ntchito ngati chipangizo choletsa kubwereranso kwa sing'anga pamapaipi amakampani.
 
Kuyika ndikofunikira
 
Kuyika valavu cheke kuyenera kulabadira zinthu zotsatirazi:
1. Musalole kuti valavu ya cheki ikhale yolemera mu payipi.Ma valve akuluakulu a cheki ayenera kuthandizidwa paokha kuti asakhudzidwe ndi kupanikizika komwe kumapangidwa ndi makina a mapaipi.
2. Mukayika, tcherani khutu kumayendedwe apakati apakati ayenera kukhala ogwirizana ndi momwe muvi wavotera ndi thupi la valve.
3. Kukweza valavu yoyang'ana yoyang'ana yoyima iyenera kuikidwa paipi yowongoka.
4. Chovala choyang'ana chokwera chokwera chokwera chiyenera kuikidwa paipi yopingasa.
 
1. Mfundo yogwirira ntchito ndi mafotokozedwe ake:
Pogwiritsa ntchito valavu iyi, sing'anga imayenda motsatira muvi womwe wawonetsedwa pachithunzichi.
2. Pamene sing'anga imayenda m'njira yodziwika, valavu ya valve imatsegulidwa ndi mphamvu yapakati;pamene sing'anga imayenda chammbuyo, chosindikizira pamwamba pa valavu ya valve ndi mpando wa valve umasindikizidwa chifukwa cha kulemera kwa valavu ya valve ndi zochita za mphamvu yobwerera kumbuyo.Tsekani pamodzi kuti mukwaniritse cholinga choletsa sing'anga kuyenda chammbuyo.
3. Malo osindikizira a thupi la valve ndi valavu clack amatengera zitsulo zosapanga dzimbiri zowotcherera.
4. Kutalika kwapangidwe kwa valve iyi kumagwirizana ndi GB12221-1989, ndipo kukula kwa kugwirizana kwa flange kumagwirizana ndi JB/T79-1994.
 
Kusungirako, Kuyika ndi Kugwiritsa Ntchito
5.1 Mapeto onse a valavu ayenera kutsekedwa, ndipo pali chipinda chowuma ndi mpweya wabwino.Ngati yasungidwa kwa nthawi yayitali, iyenera kuyang'aniridwa pafupipafupi kuti zisawonongeke.
5.2 Valavu iyenera kutsukidwa isanakhazikitsidwe, ndipo zolakwika zomwe zimachitika panthawi yoyendetsa ziyenera kuchotsedwa.
5.3 Pakuyika, muyenera kuyang'ana mosamala ngati zizindikiro ndi mayina pa valve zikukwaniritsa zofunikira kuti mugwiritse ntchito.
5.4 Valavu imayikidwa papaipi yopingasa ndi chophimba cha valve pamwamba.
9. Zolephera zotheka, Zomwe Zimayambitsa ndi Njira Zothetsera:
1. Kutayikira pamphambano ya valavu thupi ndi bonati:
(1) Ngati mtedzawo sulimbitsidwa kapena kumasulidwa mofanana, ukhoza kusinthidwanso.
(2) Ngati pali kuwonongeka kapena dothi pamtunda wosindikizira wa flange, malo osindikizira ayenera kudulidwa kapena dothi lichotsedwe.
(3) Ngati gasket yawonongeka, iyenera kusinthidwa ndi yatsopano.
2. Kutayikira pamalo osindikizira a valve clack ndi mpando wa valve
(1) Pali dothi pakati pa malo osindikizira, omwe amatha kutsukidwa.
(2) Ngati malo osindikizira awonongeka, pewaninso kapena kukonzanso ndi kukonza.
