Chifukwa Chimene Mukufunikira Kuthandizira Mpweya Wotulutsa Mpweya / Vuto mu Njira Yanu Yothirira

Chifukwa Chimene Mukufunikira Kuthandizira Mpweya Wotulutsa Mpweya / Vuto mu Njira Yanu Yothirira

 

Nthawi zambiri sitimaganizira za mpweya pamene tikukonzekera ulimi wothirira, komabe, ndi chinthu choyenera kuganizira.Zinthu zitatu zomwe zimadetsa nkhawa kwambiri ndi izi:

  1. Pamene mapaipi anu sadzaza ndi madzi, amakhala odzaza ndi mpweya.Mpweya umenewu uyenera kutulutsidwa pamene madzi amadzaza mizere.
  2. Pa ntchito yachibadwa ya ulimi wothirira wanu, mpweya wosungunuka umatuluka m'madzi ngati mawonekedwe a thovu.
  3. Pakutseka kwa makina, vacuum imatha kuwoneka ngati madzi akutuluka m'mapaipi ngati mpweya wokwanira sunalowe m'mizere.

Iliyonse mwazovutazi zitha kuthetsedwa ndi kukhazikitsa koyenera kwa mpweya wolowera mpweya ndi ma vacuum.Izi zingalepheretse kuwonongeka kwa zigawo zofunika kwambiri mu ulimi wanu wothirira.

Tidzachita zonse zomwe tingathe kuti tifotokoze zomwe zikukhudzidwa ndi mpweya ndi vacuum mupaipi yothirira;mitundu yosiyanasiyana ya ma valve: Ma valve Odzipangira (Opitirira) Otulutsa Mpweya, Mpweya / Vacuum Relief Valves ndi Combination Air / Vacuum Relief ndi Air Release Valves;ndi kuyika koyenera kwa ma valve othandizira awa.

 

Mpweya Wotsekeredwa mu Chitoliro Chopanikiza

 

Kodi mpweya umalowa bwanji m'mapaipi?

M'madera ambiri amthirira, mapaipi amakhala odzaza ndi mpweya pamene dongosololi silikugwiritsidwa ntchito.Pamene njira yanu yothirira imatseka madzi ambiri amatuluka kudzera mu emitters kapena ma valve oyendetsa galimoto omwe mungakhale nawo ndipo amasinthidwa ndi mpweya.Kuphatikiza apo, mapampu amatha kuyambitsa mpweya m'dongosolo.Pomaliza, madzi pawokha amakhala pafupifupi 2% mpweya ndi voliyumu.Mpweya wosungunuka umatuluka ndi kusintha kwa kutentha kapena kupanikizika mu dongosolo mwa mawonekedwe a thovu laling'ono.Kuthamanga kwa chipwirikiti ndi kuthamanga kwa madzi kumawonjezera mpweya wosungunuka.

 

 

Kodi mpweya wotsekeredwa umakhudza bwanji dongosolo?

Madzi amatha kuwirikiza nthawi 800 kuposa mpweya, kotero kuti mpweya wotsekeka umapanikizidwa pamene makinawo adzaza, amaunjikana pamalo okwera ndikupanga matumba a mpweya omwe angayambitse kuwonongeka.Ngati kudzikundikira kwa mpweya kumachotsedwa mwadzidzidzi kungayambitse madzi ochuluka, otchedwa nyundo yamadzi, yomwe imakhala ndi zotsatira zowononga pa mapaipi, zopangira ndi zigawo zikuluzikulu.Kufa kwa pampu ndi vuto lina.Izi zimachitika pamene kutuluka kwamadzimadzi kumayimitsidwa ndipo chopopera chopopera chikupitiriza kutembenuka kuchititsa kuti kutentha kwamadzi kukwera mpaka kufika pamtunda umene ukhoza kuwononga mpope.Kuwonongeka kwa cavitation kumadetsanso nkhawa.Cavitation ndi kupanga thovu kapena voids mu madzi kuti pamene implode kungayambitse ting'onoting'ono mantha mafunde amenenso kuwononga chitoliro makoma ndi zigawo zikuluzikulu.Mpweya wotsekeka umapezeka makamaka m'makina otsika kwambiri kapena m'mipopi yayitali pomwe matumba a mpweya amatha kuletsa kapena kuyimitsa kutuluka ngati samasulidwa.

 

Kodi njira zopewera mpweya wotsekeredwa ndi ziti?

Choyamba ndi kukhazikitsa ma valve otsitsimula kapena kutulutsa mpweya pamalo enaake mu dongosolo lanu.Izi zitha kukhala ma valve odzithandizira okha kapena ma hydrants kapena ma valve oyendetsedwa pamanja.Kenako, chepetsani nsonga zapamwamba kapena nsonga zamasanjidwe anu momwe mungathere.Kumbukirani kuti kuthamanga kwa madzi kumakankhira thovu la mpweya kupita kumalo okwera kotero konzani dongosolo lanu molingana makamaka pamapangidwe otsika kwambiri.Ngati mukugwiritsa ntchito pampu, sungani kuyamwa pang'ono pang'onopang'ono kwamadzi kuti mupewe kutulutsa mpweya ndi madzi.

 

Zovuta za Vacuum

 

Kodi vacuum ndi chiyani?

Vacuum imatanthauzidwa ngati malo opanda kanthu.Vutoli limachitika mukachotsa chinthu pamalo ozungulira ndipo palibe chomwe chingalowe m'malo mwake.Choncho ngati madzi akutuluka mupaipi ndipo mpweya sungathe kutulutsidwa, mofananamo, kuti ulowe m'malo mwake, ndiye kuti vuto la vacuum limachitika lomwe lingayambitse mapaipi kugwa.

 

Momwe mungapewere zinthu za vacuum.

Kuyika ma vacuum relief valves m'malo enaake mkati mwa ulimi wanu wothirira.Zikatere, kuchuluka kwa mpweya kumalowetsamonso kuchuluka kwa madzi otuluka m'mipope.Kupumula kwa vacuum kumalepheretsanso kuyamwa kwa dothi ndi zinyalala kudzera mu emitters, motero kumachepetsa kutsekeka kwa emitters yanu.

 

Ma valve a Air

 

Mitundu yotsatirayi ya ma valve a mpweya ndi zigawo za hydro-mechanical zomwe zimatulutsira mpweya kapena kutuluka mupaipi yothirira.Ma valve onse atatuwa nthawi zambiri amakhala otseguka, omwe nthawi zambiri amakhala ndi chipangizo chamtundu wa mpira woyandama chomwe chimamatira panjira yotseguka pomwe makina akukanikizira kenako amatsika pomwe mphamvu yamkati ifika kupsinjika kwa mumlengalenga komwe kumalola mpweya kubwerera m'dongosolo.

 

Makina Odziyimira Pawokha (Wopitilira) Wotulutsa Mpweya

Mpweya wamtundu uwu uli ndi kachidutswa kakang'ono kamene kamapitirizabe kutulutsa mpweya wochepa pambuyo poti makinawo akukakamiza ndipo mpweya waukulu / mpweya wotsekemera umatsekedwa.Kachidutswa kakang'ono kamene kamatuluka nthawi zambiri sikokwanira kulowetsa mpweya wokwanira pakatsekeka kuti tipewe kupanga vacuum.

 

Mpweya Wotulutsa / Vavu Yothandizira Kupuma

Valavu yamtunduwu nthawi zambiri imatchedwa kinetic air valve, valve yaikulu ya orifice air, vacuum breaker komanso ngakhale mpweya wothandizira mpweya.Izi zidzatulutsa mpweya wochuluka pamene mapaipi akudzaza kapena kukanikiza komanso kulowetsa mpweya m'dongosolo pamene mizere ikutha kapena kuchepetsa kuthamanga.Komabe, sangathe kumasula timatumba tating'ono ta mpweya totsalira timene timapanga pamene akugwira ntchito.Chithunzi chili m'munsichi chikuwonetsa kachitidwe ka Vavu ya Air/Vacuum.

  1. Mpweya wodutsa mpweya monga dongosolo limadzaza ndi madzi.
  2. Dongosolo lodzaza ndi kupanikizika, valavu imadzaza madzi ndikutseka mpweyawo.
  3. Pakutseka kwadongosolo, kutsika kwapakati kumapangitsa kuti kuyandama kugwe ndipo mpweya umakokedwa munjira yoletsa kutsekeka.

 

 

Kuphatikiza Air / Vacuum Relief ndi Air Release Valve

Monga momwe dzinalo likusonyezera, valavu iyi, yomwe imadziwikanso kuti valavu iwiri ya orifice, imagwira ntchito zina ziwirizo mu unit imodzi.Kulola mpweya wochuluka kulowa ndi kutuluka pakufunika, komanso, kutulutsa mpweya wochepa mosalekeza panthawi yogwira ntchito.Ma valve ophatikizana a mpweya / vacuum angagwiritsidwe ntchito m'malo mwa mitundu ina.

Onani kusankha kwathu kwa Air/Vacuum Relief Valves Pano.

 

Kuyika

 

Ma valve a mpweya amagwiritsidwa ntchito pazitsulo zazikulu zamadzi ndi mizere yotumizira, yomwe imayikidwa pazitali kwambiri mu dongosolo;pa drip line lateral malekezero;pakusintha kwamakalasi, monga, kutsetsereka kusanachitike komanso pambuyo pake;m'njira zazitali zopingasa;nthawi zambiri isanayambe kapena itatha kudzipatula kapena ma valve otseka;ndi mbali ya kutulutsa kwa mapampu a chitsime chakuya.Ndikofunika kuti mpweya wa mpweya ukhazikitsidwe pamalo okwera chifukwa mpweya umakwera, ndipo monga tafotokozera pamwambapa, kuthamanga kwa madzi kudzakankhira mpweya kumalo okwera kwambiri.Kukonzekera kungawoneke kukhala kovuta, koma kuyika bwino ndikofunikira kuti njira yothirira igwire bwino ntchito.

Kuyika bwino ndikofunikiranso kwambiri.Ma valve ayenera kuikidwa molunjika kokha.Kuyika kokhazikika kumakhala pamwamba pa chokwera chitoliro chofanana ndi cholowera cha valve.Nthawi zambiri, valavu yodzipatula (yotseka) imayikidwa pansipa kuti isamalidwe mosavuta.

 

Kukula kwa Vavu

 

Kufananiza kukula kwa valavu ndi kukula kwa chitoliro ndiupangiri wokhazikika pakupumira pang'ono kwa mpweya / vacuum.Pamafamu athu ang'onoang'ono kapena amthirira a eni nyumba okhala ndi 1 "ndi pansi pa chitoliro, ma valve athu a mpweya ½" - 1" ndi okwanira pamene akugwirizana ndi kukula kwa chitoliro.Opanga ambiri amalimbikitsa 2 "ndipo ma diameter a mapaipi amafunikira kukula kwa valavu 2".

Kwa machitidwe akuluakulu kapena ovuta kwambiri kuwerengera kuti mudziwe kukula koyenera, kuchuluka ndi malo a ma valve pa ntchito iliyonse kungakhale kovuta kwambiri.Tikukulimbikitsani kulankhulana ndi katswiri wothirira wothirira kuti agwiritse ntchito mwaukadaulo.
