Muyenera kugula mavavu a mpira, koma onani zosankha za "1-chidutswa" ndi "2-piece". Sankhani yolakwika, ndipo mutha kukumana ndi zotulutsa zokhumudwitsa kapena kudula valavu yomwe ikanakonzedwa.

Kusiyana kwakukulu ndiko kumanga kwawo. A1-chidutswa cha mpira valveali ndi thupi limodzi, lolimba ndipo silingathe kupatulidwa kuti likonzedwe. A2-chidutswa cha mpira valveamapangidwa ndi zigawo ziwiri zosiyana, kulola kuti disassembled kukonza zigawo zamkati.

Izi ndi mwatsatanetsatane zomwe ndimakambirana nthawi zonse ndi anzanga ngati Budi ku Indonesia. Kwa manejala ogula, kumvetsetsa kusiyana kumeneku ndikofunikira. Zimakhudza mwachindunji mtengo wa polojekiti, kukonza kwanthawi yayitali, komanso kukhutira kwamakasitomala. Zingawoneke ngati tsatanetsatane yaying'ono, koma kusankha molondola ndi njira yosavuta yoperekera mtengo waukulu kwa makasitomala ake, kuchokera kwa makontrakitala ang'onoang'ono kupita kwa makasitomala akuluakulu ogulitsa mafakitale. Chidziwitso ichi ndi chofunikira pa mgwirizano wopambana.

Kodi pali kusiyana kotani pakati pa 1 piece ndi 2 piece mpira valve?

Mukuyesera kusankha vavu yotsika mtengo kwambiri. Popanda kumvetsetsa kusiyana kwa mapangidwewo, mutha kusankha valavu yotsika mtengo yomwe ingakuwonongereni ndalama zambiri pakapita nthawi ndikusintha ntchito.

Valve yachidutswa 1 ndi gawo losindikizidwa, lotayidwa. Valavu ya 2-piece imawononga pang'ono koma ndi chinthu chokonzedwa, chanthawi yayitali. Chisankhocho chimadalira kulinganiza mtengo woyambira ndi kufunikira kokonzanso mtsogolo.

Kuti tithandize Budi ndi gulu lake kupanga malingaliro abwino, nthawi zonse timagwiritsa ntchito tebulo losavuta lofananizira. Izi zimathetsa kusiyana kothandiza kuti makasitomala ake athe kuwona zomwe akulipira. Kusankha "koyenera" nthawi zonse kumatengera zosowa za ntchitoyo. Kwa mzere waukulu wothamanga kwambiri, kukonzanso ndikofunikira. Kwa mzere wothirira kwakanthawi, valavu yotaya imatha kukhala yangwiro. Cholinga chathu ku Pntek ndikupatsa mphamvu anzathu ndi chidziwitso ichi kuti athe kutsogolera makasitomala awo moyenera. Gome ili pansipa ndi chida chomwe ndimagawana ndi Budi kuti izi zimveke bwino.

Kumvetsetsa tchatichi ndi gawo lofunikira kwambiri pakusankha bwino.

Kodi pali kusiyana kotani pakati pa gawo 1 ndi gawo 2 valavu ya mpira?

Mumamva kasitomala akufunsa "gawo 1" kapena "gawo 2" valavu. Kugwiritsa ntchito mawu olakwika ngati awa kungayambitse chisokonezo, kuyitanitsa zolakwika, ndikupereka mankhwala olakwika pantchito yovuta.

"Gawo 1" ndi "Gawo 2" sizinthu zamakampani. Mayina olondola ndi “chidutswa chimodzi” ndi “chidutswa chiŵiri.” Kugwiritsa ntchito mawu oyenerera ndikofunikira kuti pakhale kulumikizana komveka bwino komanso kuyitanitsa kolondola mumayendedwe ogulitsa.

Nthawi zonse ndimatsindika kufunika kwa chilankhulo cholondola kwa Budi ndi gulu lake logula zinthu. Mu malonda a padziko lonse, kumveka ndi chirichonse. Kusamvetsetsana pang'ono mu terminology kumatha kupangitsa kuti chidebe cha zinthu zolakwika chifike, zomwe zimapangitsa kuchedwetsa kwakukulu ndi mtengo wake. Timawatcha "chidutswa chimodzi" ndi "zidutswa ziwiri" chifukwa zimalongosola momwe thupi la valve limapangidwira. Ndizosavuta komanso zomveka. Pamene gulu la Budi limaphunzitsa anthu ogulitsa malonda, ayenera kutsindika kugwiritsa ntchito mawu olondola awa. Imakwaniritsa zinthu ziwiri:

1. Imateteza Zolakwa:Zimatsimikizira kuti malamulo ogula omwe amatumizidwa kwa ife ku Pntek ndi olondola, kotero timatumiza katundu weniweni womwe amafunikira popanda kumveka kulikonse.
2. Amamanga Mphamvu:Pamene ogulitsa ake angathe kukonza kasitomala modekha (“Mukufuna valavu ya 'zigawo ziwiri', ndiroleni ndikufotokozereni ubwino wake…”), amadziika ngati akatswiri, kukulitsa chidaliro ndi kukhulupirika. Kulankhulana momveka bwino sikumangokhalira kuchita bwino; ndi gawo lalikulu labizinesi yopambana, yaukadaulo.

Kodi valavu ya 1 piece mpira ndi chiyani?

Mufunika valavu yosavuta, yotsika mtengo yogwiritsira ntchito yosafunikira. Mukuwona valavu yotsika mtengo ya 1-chidutswa koma kuda nkhawa kuti mtengo wake wotsika umatanthauza kuti idzalephera nthawi yomweyo, ndikuyambitsa mavuto ambiri kuposa momwe imayenera.

Valavu ya mpira wa 1-piece imapangidwa kuchokera ku thupi limodzi lopangidwa. Mpira ndi zisindikizo zimayikidwa, ndipo valavu imasindikizidwa kosatha. Ndi njira yodalirika, yotsika mtengo yogwiritsira ntchito zomwe kukonzanso sikofunikira.

Ganizirani za valavu ya mpira wa 1 ngati kavalo wogwirira ntchito zosavuta. Mawonekedwe ake ndi thupi lake - ndi chidutswa chimodzi cholimba cha PVC. Mapangidwe awa ali ndi zotsatira zazikulu ziwiri. Choyamba, ili ndi njira zochepa zotayikira, popeza palibe misomali ya thupi. Izi zimapangitsa kuti ikhale yodalirika pamtengo wake. Chachiwiri, ndizosatheka kutsegula kuti mutumikire zigawo zamkati. Ngati chisindikizo chatha kapena mpira wawonongeka, valavu yonse iyenera kudulidwa ndikusinthidwa. Ichi ndichifukwa chake timawatcha "mavavu otaya" kapena "otaya". Nthawi zambiri amakhala ndi "doko lochepetsedwa,” kutanthauza kuti dzenje la mpirawo ndi laling'ono kuposa m'mimba mwake la chitoliro, lomwe limatha kuletsa kuyenda pang'ono.

• Njira zothirira m'nyumba.
• Mizere ya madzi akanthawi.
• Mapulogalamu otsika kwambiri.
• Nthawi iliyonse yomwe mtengo wa ntchito yosinthira ndi yocheperapo kuposa mtengo wapamwamba wa valve yokonzanso.

Kodi valavu yamagulu awiri ndi chiyani?

Pulojekiti yanu ikuphatikiza njira yovuta yomwe singakwanitse kutsika. Mukufunikira valavu yomwe siili yolimba koma imatha kusungidwa mosavuta kwa zaka zambiri popanda kutseka dongosolo lonse.

Vavu yamagulu awiri imakhala ndi thupi lopangidwa kuchokera ku zigawo ziwiri zazikulu zomwe zimalumikizana. Kapangidwe kameneka kamapangitsa kuti valavu ikhale yosiyana kuti iyeretse, kutumikira, kapena kubwezeretsa mpira wamkati ndi zisindikizo.

Thevalavu yamitundu iwirindiye chisankho chokhazikika cha akatswiri pamapulogalamu ovuta kwambiri. Thupi lake limapangidwa m'magawo awiri. Theka limodzi limakhala ndi ulusi, ndi zina zomangiramo, kugwedeza mpira ndi zisindikizo (monga mipando ya PTFE yomwe timagwiritsa ntchito ku Pntek) molimba. Ubwino waukulu ndikukonza. Ngati chisindikizo chimatha pambuyo pa zaka zambiri zautumiki, simufunika chocheka chitoliro. Mutha kungopatula valavu, kumasula thupi, kusintha zida zosindikizira zotsika mtengo, ndikuziphatikizanso. Yabweranso mumphindi zochepa. Ma valve awa amakhala pafupifupi nthawi zonse "doko lathunthu,” kutanthauza kuti bowo mumpira ndi lofanana ndi chitoliro chofanana ndi chitoliro, kuonetsetsa kuti ziro sizimadutsa.

• Industrial process mizere.
• Njira zazikulu zoperekera madzi ku nyumba.
• Pampu ndi kusefa kudzipatula.
• Dongosolo lililonse lomwe kuchuluka kwa kuthamanga kuli kofunikira komanso kudalirika kwanthawi yayitali ndiye chinthu chofunikira kwambiri.

Mapeto

Chosankhacho ndi chophweka: ma valve a 1-piece ndi otsika mtengo ndipo amatha kutaya ntchito zosafunikira. Ma valve a 2-piece ndi okhoza kukonzedwa, oyenda mokwanira pamakina aliwonse omwe kudalirika komanso kufunika kwa nthawi yayitali ndikofunikira kwambiri.
