A.Kuyika vavu pachipata
Chipata cha valve, yomwe imatchedwanso kuti valve valve, ndi valve yomwe imagwiritsa ntchito chipata kuti iwonetsetse kutsegula ndi kutseka, ndikusintha kayendedwe ka mapaipi ndikutsegula ndi kutseka payipi mwa kusintha gawo la mtanda.Ma valve a zipata amagwiritsidwa ntchito kwambiri pamapaipi omwe amatsegula kapena kutseka kwathunthu pakati pamadzimadzi. Kuyika ma valve pachipata nthawi zambiri kulibe zofunikira zolowera, koma sikungatembenuzidwe.
B.Kuyika kwadziko valavu
Valavu ya globe ndi valve yomwe imagwiritsa ntchito diski ya valve kuti iwonetsetse kutsegula ndi kutseka. Sinthani kuyenda kwapakati kapena kudula gawo lapakati posintha kusiyana pakati pa diski ya valve ndi mpando wa valve, ndiko kuti, kusintha kukula kwa gawo la njira. Mukayika valavu yotseka, chidwi chiyenera kuperekedwa ku kayendetsedwe ka madzi.
Mfundo yomwe iyenera kutsatiridwa poika valavu ya globe ndi yakuti madzi a m'mipope amadutsa mu dzenje la valve kuchokera pansi mpaka pamwamba, omwe amadziwika kuti "otsika ndi otsika", ndipo saloledwa kuyiyika kumbuyo.
C.Kuyika valavu yoyendera
Onani valavu, yomwe imatchedwanso check valve ndi valve ya njira imodzi, ndi valve yomwe imatsegula ndi kutseka pansi pa zochitika za kusiyana kwapakati pakati pa kutsogolo ndi kumbuyo kwa valve. Ntchito yake ndikupangitsa kuti sing'anga iziyenda mbali imodzi yokha ndikuletsa sing'angayo kubwerera kumbuyo. Malinga ndi mapangidwe awo osiyanasiyana,fufuzani ma valve zikuphatikizapo Nyamulani mtundu, swing mtundu ndi gulugufe wafer mtundu. Nyamulani valavu cheke amagawidwa yopingasa ndi ofukula. Pamene khazikitsa ndichekeni valavu, chidwi chiyenera kuperekedwanso ku kayendetsedwe ka kayendedwe ka sing'anga ndipo sichikhoza kukhazikitsidwa mobwerera.
D.Kuyika valavu yochepetsera kuthamanga
Valavu yochepetsera kupanikizika ndi valavu yomwe imachepetsa kukakamiza kolowera kumayendedwe ena ofunikira potuluka mwa kusintha, ndipo imadalira mphamvu ya sing'anga yokhayo kuti ingopangitsa kuti kutulutsako kukhale kokhazikika.
1. Gulu la ma valve ochepetsera kuthamanga lomwe limayikidwa molunjika limayikidwa pakhoma pamtunda woyenera kuchokera pansi; gulu la valve kuchepetsa kuthamanga lomwe limayikidwa mozungulira nthawi zambiri limayikidwa pa nsanja yokhazikika.
2. Chitsulo chogwiritsira ntchito chimayikidwa pakhoma kunja kwa ma valve awiri olamulira (omwe amagwiritsidwa ntchito pa ma valve a globe) kuti apange bracket, ndipo chitoliro chodutsa chimamangiriridwanso pazitsulo kuti chikhale chofanana ndi kugwirizanitsa.
3. Vavu yochepetsera kupanikizika iyenera kuikidwa molunjika paipi yopingasa, ndipo sayenera kupendekera. Muvi womwe uli pa thupi la vavu uyenera kuloza komwe kukuyenda kwapakati, ndipo sayenera kuikidwa kumbuyo.
4. Ma valve a globe ndi magetsi othamanga kwambiri ndi otsika ayenera kuikidwa kumbali zonse ziwiri kuti ayang'ane kusintha kwa mphamvu isanayambe kapena itatha. Kutalika kwa payipi kuseri kwa valavu yochepetsera kupanikizika kuyenera kukhala 2#-3# yokulirapo kuposa m'mimba mwake ya chitoliro cholowera kutsogolo kwa valavu, ndipo chitoliro chodutsa chiyenera kukhazikitsidwa kuti chikonze.
5. Chitoliro chofanana ndi chitoliro cha nembanemba chochepetsera valavu chiyenera kulumikizidwa ndi payipi yotsika. Mapaipi apansi apansi ayenera kukhala ndi ma valve otetezera kuti atsimikizire kuti dongosololi likuyenda bwino.
6. Mukagwiritsidwa ntchito pochepetsera nthunzi, chitoliro chopopera chiyenera kukhazikitsidwa. Kwa machitidwe a mapaipi omwe amafunikira kuyeretsedwa kwakukulu, fyuluta iyenera kuikidwa pamaso pa valve yochepetsera kuthamanga.
7. Pambuyo pa gulu la valve kuchepetsa kupanikizika, valavu yochepetsera kuthamanga ndi valve yotetezera iyenera kuyesedwa, kuthamangitsidwa ndi kusinthidwa malinga ndi zofunikira za mapangidwe, ndipo chizindikiro chosinthidwa chiyenera kupangidwa.
8. Mukatsuka valavu yochepetsera kuthamanga, tsekani valavu yochepetsera mphamvu ndikutsegula valavu yothamangitsira.
E.Kuyika misampha
Ntchito yaikulu ya msampha wa nthunzi ndiyo kutulutsa madzi osungunuka, mpweya ndi mpweya wa carbon dioxide mu nthunzi mumchitidwe wa nthunzi mwamsanga; pa nthawi yomweyo, akhoza basi kuteteza kutayikira kwa nthunzi kumlingo waukulu. Pali mitundu yambiri ya misampha, iliyonse imakhala ndi machitidwe osiyanasiyana.
1. Ma valve otseka (ma valve otseka) ayenera kukhazikitsidwa patsogolo ndi pambuyo pake, ndipo fyuluta iyenera kuikidwa pakati pa msampha ndi valavu yotseka kutsogolo kuti chiwonongeko cha m'madzi otsekedwa zisatseke msampha.
2. Chitoliro choyendera chiyenera kuikidwa pakati pa msampha wa nthunzi ndi valve yotseka kumbuyo kuti muwone ngati msampha wa nthunzi umagwira ntchito bwino. Ngati nthunzi yochuluka imatulutsa pamene chitoliro choyendera chikutsegulidwa, zikutanthauza kuti msampha wa nthunzi wathyoka ndipo uyenera kukonzedwa.
3. Cholinga chokhazikitsa chitoliro chodutsa ndikutulutsa madzi ambiri osungunuka panthawi yoyambira ndikuchepetsa kutsitsa kwa msampha.
4. Pamene msampha umagwiritsidwa ntchito kukhetsa madzi osungunuka a zida zotenthetsera, uyenera kuyikidwa pansi pazida zotenthetsera, kuti chitoliro cha condensate chibwererenso molunjika ku msampha wa nthunzi kuti madzi asasungidwe. zida zotenthetsera.
5. Malo oyikapo ayenera kukhala pafupi ndi malo okhetsera madzi momwe angathere. Ngati mtunda uli patali kwambiri, mpweya kapena nthunzi zimawunjikana mu chitoliro chowonda kutsogolo kwa msampha.
6. Pamene payipi yopingasa ya chitoliro chachikulu cha nthunzi ndi yaitali kwambiri, vuto la ngalande liyenera kuganiziridwa.
F.Kuyika kwa valve yotetezera
Valavu yotetezera ndi valve yapadera yomwe mbali zotsegula ndi zotseka zimakhala zotsekedwa nthawi zambiri pansi pa mphamvu yakunja. Pamene kupanikizika kwa sing'anga mu zipangizo kapena payipi ikukwera kupitirira mtengo wotchulidwa, imatulutsa sing'anga kupita kunja kwa dongosolo kuti ateteze kupanikizika kwapakatikati mu payipi kapena zipangizo kuti zisapitirire mtengo wotchulidwa. .
1. Musanakhazikitse, mankhwalawa ayenera kuyang'aniridwa mosamala kuti atsimikizire ngati pali chiphaso chovomerezeka ndi buku la mankhwala, kuti afotokoze kupanikizika kosalekeza pochoka ku fakitale.
2. Valve yachitetezo iyenera kukonzedwa pafupi kwambiri ndi nsanja kuti iwonetsedwe ndi kukonza.
3. Valve yachitetezo iyenera kuyikidwa molunjika, sing'angayo iyenera kutuluka kuchokera pansi kupita pamwamba, ndipo tsinde la valve liyenera kuyang'aniridwa.
4. Mwachizoloŵezi, ma valve otseka sangathe kukhazikitsidwa kale komanso pambuyo pa valavu yachitetezo kuti atsimikizire chitetezo ndi kudalirika.
5. Kuchepetsa kuthamanga kwa ma valve otetezeka: sing'anga ikakhala yamadzimadzi, nthawi zambiri imatulutsidwa mu payipi kapena kutsekedwa; pamene sing'angayo ndi gasi, nthawi zambiri imatulutsidwa kumlengalenga;
6. Sing'anga yamafuta ndi gasi nthawi zambiri imatha kutulutsidwa mumlengalenga, ndipo potulutsira chitoliro cha valve yachitetezo iyenera kukhala 3m pamwamba kuposa nyumba zoyandikana nazo, koma zotsatirazi ziyenera kutayidwa motsekedwa kuti zitsimikizire chitetezo.
7. Kutalika kwa chitoliro cha anthu kuyenera kukhala kofanana ndi kukula kwa chitoliro cha valve; kutalika kwa chitoliro chotulutsa sikuyenera kukhala kocheperako kuposa kutulutsa kwa valve, ndipo chitoliro chotulutsa chiyenera kupita panja ndikuyika ndi chigongono, kuti chitolirocho chiyang'ane malo otetezeka.
8. Pamene valavu yachitetezo imayikidwa, pamene kugwirizana pakati pa valavu yotetezera ndi zipangizo ndi payipi ikutsegula kuwotcherera, kutsegula kwake kuyenera kukhala kofanana ndi m'mimba mwake mwadzina la valve yotetezera.
