Kukambitsirana pakugwiritsa ntchito ma valve owonetsa ma valve owongolera ma hydrant m'nyumba zokwera

Chidule: Lingaliro la ma valve okwera okwera omangira chowongolera choyatsira moto pogwiritsa ntchito zokambirana zama valve
Mawu ofunikira: valavu yamagetsi yamagetsi yamagetsi yamagetsi yamoto yokwera kwambiri
Malinga ndi zomwe zili mu "Code for Fire Prevention Design of High-Rise Civil Buildings", m'kati mwa makina opangira moto wamkati, payipi yamadzi iyenera kugawidwa m'magawo angapo **, ndipo valavu iyenera kukhala ndi zizindikiro zoonekeratu zotseguka ndi zotseka. Izi zili choncho kuti chiwerengero cha ma hydrant standpipes sichicheperapo pamene chitoliro chikugwiritsidwa ntchito.
Ndi chitukuko cha zomangamanga zamakono, kumanga mapaipi osiyanasiyana pofuna kukongola kuyenera kubisika momwe kungathekere kukongoletsa, kotero, mapaipi a hydrant padenga, chubu bwino, ali ponseponse, koma ili ndi vuto, ndilo valve yolamulira. chitoliro choyatsira moto sichingayang'anire, kuyambitsa chowongolera moto chikhoza kugwiritsidwa ntchito bwino. Nazi zitsanzo:
Ntchito ya "State Grid Control Center of Ministry of Electric Power" imakhudza malo omanga oposa 50,000 square metres, okhala ndi zipinda zitatu zapansi ndi 27 pamwamba pa nthaka. Kutalika kwa nyumbayi kumapitilira 110 metres. Ndi nyumba yanzeru yophatikizira kupanga ndi kutumiza, ntchito zamaofesi ndi misonkhano, ndipo kuchuluka kwake kwazinthu zopanga zokha ndizosowa ku China. Popanga makina opopera mankhwala opangira vinyo, ndimagwiritsa ntchito ma valve owonetserako kutsogolo kwa zizindikiro zonse zakuyenda kwa madzi, kotero kuti mawonekedwe a dongosolo akhoza kuwonetsedwa kumalo olamulira moto, ndipo mavuto angapezeke powonekera bwino. Kuonjezera apo, kulamulira kwa madzi a moyo ndi kumenyana ndi moto, ndi kuyamba ndi kuyimitsidwa kwa mpope wamoto kumayang'aniridwa bwino. Ndi valavu yokhayo yamagetsi opangira moto molingana ndi mafotokozedwe a valavu wamba, ili ndi zizindikiro zoonekeratu za kutsegula ndi kutseka, koma sizingasonyezedwe mu malo oyendetsera moto, kuwonjezera apo, ma valve awa ali mu chubu bwino. ndi denga la zosowa zokongoletsa, khalidwe la ogwira ntchito panopa silingatsimikizire kudalirika kwa dongosolo. M'dongosolo lachitetezo chamoto pakuvomerezedwa, ngakhale utsogoleri wa likulu la projekiti yautumiki, magawo omanga ndi mayunitsi apangidwe ndizovuta kwambiri, wapanga kutumizidwa ndi kukonzanso koyambirira, kutsatiridwa bwino, koma pogwira ntchito ya dipatimenti yozimitsa moto zenizeni. kuvomereza, koma pali vuto, pali chopopera chamoto pa standpipe mulimonsenso sichingatuluke m'madzi, ndi zina zinayi ndizabwinobwino, Sitingapeze vuto pamalo owongolera moto. Pambuyo poyang'anitsitsa, adapeza kuti ma valve oyendetsa kumapeto onse awiri akukwera adatsekedwa chifukwa chokonzekera, ndipo ogwira ntchito sanatsegule ma valve pambuyo pokonza, zomwe zimapangitsa kuti moto usagwe.
Ndikuganiza kuti, ngati aliyense amaona kuti ndi yofunika kwambiri, amawonekerabe vuto lamtunduwu, ndipo nthawi zambiri zimakhala zovuta kufa ziwalo zambiri sadziwa kuti ndi vuto lanji lomwe lidzawonekere. Izi zikugwirizana ndi ngati makina oyendetsera moto ndiye chinsinsi chakugwiritsa ntchito bwino kwamavuto, ndikupewa izi kuwoneka * * njira yodalirika ndikuwotcha ma hydrant system ma valve owongolera amayikidwa mu valavu ya chizindikiro, ndi valavu yotseguka kuti iwonetse pakati. wa kuwongolera moto, kotero kuti oyang'anira oyang'anira kuyang'anira, ngakhale mtengo wakula, komabe, Chiŵerengero cha ndalama ku dongosolo lonse lamagetsi oyaka moto akadali ochepa kwambiri, ndipo angapangitse kuti chitetezo chonse cha moto chitetezeke ** kusintha, chomwe Ndikuganiza kuti ndizofunikira ndalama.
Vavu yowongolera molingana ndi kagayidwe kazinthu zamapangidwe (1) kudzera pampando umodzi wowongolera valavu: valavu * * yogwiritsidwa ntchito kwambiri, imakhala ndi kutayikira kwina  kupanikizika kovomerezeka kosiyana siyana  kuyenda kovutirapo ndi mawonekedwe a mawonekedwe osavuta, motero ndikoyenera kutayikira kolimba, kusiyana kwakung'ono kwapang'onopang'ono kwa sing'anga yoyera, koma mawonekedwe ang'onoang'ono a kukula kwa dzina la valve (DN (2) molunjika kudzera pamipando iwiri yowongolera: mosiyana ndi valavu yowongoka yokhala ndi mpando umodzi, ili ndi mawonekedwe a kutayikira kwakukulu komanso kusiyana kwakukulu kovomerezeka, kotero ndiyoyenera pamisonkhano yapa media yoyera yokhala ndi zofunikira zotayirira komanso zazikulu. kusiyana kwa kuthamanga kwa ntchito. Chisamaliro chiyenera kulipidwa ngati kuchuluka kwa kutayikira kwa valve kumakwaniritsa zofunikira zoyendetsera ndondomeko posankha valavu.
(3) Valavu ya manja: valavu ya manja imagawidwa kukhala chisindikizo chimodzi ndi kusindikiza kawiri zigawo ziwiri, zoyambazo ndizofanana ndi valavu imodzi yapampando, yoyenera pazochitika zapampando umodzi. Chotsatirachi ndi chofanana ndi valavu yokhala ndi mipando iwiri, yoyenera pazochitika ziwiri za valve. Valve yamanja imakhalanso ndi mawonekedwe okhazikika, kutsitsa kosavuta komanso kutsitsa, koma mtengo wake ndi 50% ~ 200% kuposa valavu yapampando umodzi, valavu yapampando iwiri, imafunikiranso gasket yapadera yokhotakhota. Valavu ya sleeve ndiyotsika kwambiri kuposa valavu imodzi-mpando, valavu yapampando iwiri.
(4) valavu ya Angle, mawonekedwe a throttle ndi ofanana ndi valavu yapampando umodzi, koma kuyenda kwa thupi ndikosavuta, komwe kumagwira ntchito kutayikira kumafuna  nthawi zoyera zapakati ndi zofunikira za kupanikizika kosiyana ndi chitoliro cha makona anayi.
(5) valavu yanjira zitatu: ili ndi mayendedwe a 3, imatha kusintha valavu iwiri yowongoka yokhala ndi mpando umodzi, yomwe imagwiritsidwa ntchito ngati shunt ndi confluence ndikuyenda magawo awiri, kusiyana kwa kutentha sikupitilira 150 ℃. Pamene DN≤80 mm, valavu ya confluence ingagwiritsidwe ntchito pazochitika za shunt.
(6) Valavu ya diaphragm: njira yosavuta yoyendera, diaphragm imakhala ndi magwiridwe antchito ena oletsa dzimbiri, oyenera sing'anga yodetsedwa, sing'anga yofooka yambiri yoduka kawiri.
Vavu ya butterfly (7) : ndi yofanana kuyika gawo la thupi, ndipo thupi limafanananso ndi mpando, kotero kuti "kudziyeretsa" ndikwabwino, zina  kulemera kwa voliyumu. Oyenera odetsedwa sing'anga ndi lalikulu m'mimba mwake, lalikulu otaya, lalikulu kuthamanga kusiyana. Pamene Dn> 300 mm, nthawi zambiri amamaliza ndi valavu butterfly.
(8) Vavu ya mpira: "O" mtundu wa valavu ya mpira ikatsegulidwa kwathunthu kwa valavu yotseguka, "kudziyeretsa" ndikwabwinoko, koyenera makamaka kwaukhondo, fiber medium nthawi ziwiri zodulira. Vavu ya "V" BALL ili ndi mawonekedwe osinthika pafupifupi ofanana, oyenera osayera, okhala ndi fiber media, nthawi zowongolera zosinthika. Ma valve a mpira ndi okwera mtengo kwambiri.
(9) Eccentric rotary valve: valavu pakati pa gulugufe ndi valavu ya mpira, "kudziyeretsa" ntchito yabwino, yoyendetsera bwino ntchito, ikhoza kudulidwa, kotero ndi yoyenera kwa sing'anga yodetsedwa, zofunikira zowonongeka pazochitika zazing'ono zolamulira, koma mtengo wa valve ndi wokwera mtengo.
Zoyamba 6 mwazinthu 9 izi ndi mavavu owongolera stroko, ndipo 3 yomaliza ndi mavavu owongolera sitiroko. Monga kugwiritsa ntchito valavu yowongolera, ndikofunikira kufotokozera momveka bwino mawonekedwe awo ndi zinthu zomwe zimafunikira chisamaliro. Mitundu yonse yazinthu zosiyanasiyana, zotsogola zimasinthika m'magulu 9 awa azinthu, ndikosavuta kumvetsetsa magulu 9 azinthu kuti azitha kugwiritsa ntchito bwino zinthu zina.
