Kodi mavuto ogwiritsira ntchito ma valve a chipata ndi ati?

Mwayika valavu ya chipata, koma tsopano muyenera kuchepetsa kuyenda kwa madzi, osati kuyimitsa. Kuyesa kugwiritsa ntchito valavu ya chipata pachifukwa ichi kungawononge valavu mwachangu ndikuyambitsa mavuto mu payipi yanu.

Ma valve a chipata ndi osagwira bwino ntchito. Amatha kugwedezeka ndikupangitsa kuti mipando ndi ma disc awonongeke akatsegulidwa pang'ono. Amachedwanso kugwira ntchito ndipo amatha kutsekeka chifukwa cha kusungunuka kwa matope.

Ma valve a chipata amapangidwira ntchito imodzi: kutseguka kwathunthu kapena kutsekedwa kwathunthu.

Kodi ndingagwiritse ntchito valavu ya saddle pa PVC?

Muyenera kugwiritsa ntchito chingwe chamadzi cha PVC chomwe chilipo kale kuti mulumikizane pang'ono. Valavu yoyika chidebe cha mpando imawoneka ngati yankho lachangu komanso losavuta, koma mukuopa kuti ingawononge chitoliro cha pulasitiki.

Ayi, simuyenera kugwiritsa ntchito muyezovalavu ya chishalopa chitoliro cha PVC. Ma valve a chishalo amagwira ntchito pobowola chitolirocho, zomwe zimapangitsa kuti PVC ing'ambike ndikulephera, zomwe zimapangitsa kuti pakhale kutuluka madzi ambiri.

Iyi ndi mfundo yofunika kwambiri yachitetezo yomwe ndimayigogomezera nthawi zonse ndi Budi. Ma valve a saddle adapangidwira mapaipi olimba achitsulo monga mkuwa. Ali ndi pini yakuthwa yomwe mumayikoka kuti muboole khoma la paipi kuti mupange pompo yamadzi. Njira iyi ndi tsoka kwa PVC. PVC ndi yolimba, komanso ndi chinthu chosagwira ntchito bwino. Izi zikutanthauza kuti ngati mupanga malo akuthwa a kupsinjika, monga dzenje lochokera ku pini yoboola, ming'alu imayamba mosavuta ndikudutsa pakhoma la paipi. Kupanikizika kosalekeza kwa madzi kudzagwiritsa ntchito malo ofooka awa. Sangatuluke nthawi yomweyo, koma pakapita nthawi, ndi kusintha kwa kuthamanga ndi kutentha, dzenje laling'ono limenelo lidzakhala ming'alu yayikulu ndipo paipi idzaphulika. Njira yolondola yolumikizira mzere wa PVC ndikugwiritsa ntchito "t-shirt yokwera pahatchi"kapena" chogwirira." Zolumikizira izi zimamatira kapena kulumikiza chitolirocho, kenako mumagwiritsa ntchito chobowolera kuti mupange dzenje loyera, zomwe zimapangitsa kuti chitolirocho chikhale cholimba komanso chosataya madzi popanda kuwononga kapangidwe ka chitolirocho.

Kodi valavu yolowera pachipata yomwe imagwiritsidwa ntchito kwambiri komanso yomwe imagwiritsidwa ntchito kwambiri ndi iti?

Muyenera kusunga valavu yodziwika bwino ya chipata chogawa madzi. Mukufuna kupereka yomwe makasitomala anu amafunsa kawirikawiri kuti zinthu zanu zikhale zosavuta.

Mtundu wofala kwambiri komanso wogwiritsidwa ntchito kwambiri nditsinde losakwera (NRS), mphero yolimba,valavu ya chipata yokhala ndi mpando wolimbaImakondedwa chifukwa cha kapangidwe kake kakang'ono, kulimba, komanso koyenera kugwiritsa ntchito madzi apansi panthaka komanso mapaipi wamba.

Mtundu uwu ndi ntchito yodziwika bwino m'makampani opanga madzi, ndipo ndi valavu yomwe makasitomala a Budi mwina amaidziwa bwino. Tiyeni tiwone chifukwa chake ndi yotchuka kwambiri. "Sinde losakwera" limatanthauza kuti ndi laling'ono kwambiri, lomwe ndi labwino kwambiri poyiyika m'malo opapatiza kapena pansi pa nthaka, chifukwa simukusowa malo owonjezera kuti tsinde lisunthire mmwamba ndi pansi. "Sinde lolimba" limatanthauza chipata chosavuta, cholimba, chokhala ndi chidutswa chimodzi mkati, chomwe ndi chodalirika komanso chotsika mtengo. Gawo lofunika kwambiri ndi "chokhazikika bwino." Izi zikutanthauza kuti chipata chachitsulo chimakutidwa ndi rabara (monga EPDM). Valavu ikatseka, mphero ya rabara iyi imakanikiza thupi losalala lamkati la valavu, ndikupanga chisindikizo cholimba ngati thovu. Kapangidwe kameneka ndi kabwino kwambiri potseka kuposa mipando yakale yachitsulo ndi chitsulo ndipo kamaletsa dothi kuti lisagwidwe pansi, ndikutsimikizira chisindikizo chabwino kwa nthawi yayitali. Ndi kuphatikiza kwa kapangidwe kakang'ono, kodalirika, komanso kosataya madzi komwe kwapangitsa kuti ikhale muyezo wapadziko lonse lapansi wamagetsi amadzi.

Kodi njira zina zosinthira valavu ya chipata ndi ziti?

Mukufuna valavu yoyatsa/kutseka, koma valavu yolowera ikuwoneka yochedwa kwambiri kapena si yoyenera kugwiritsidwa ntchito. Muyenera kudziwa njira zina zomwe zilipo kuti musankhe bwino.

Njira ziwiri zazikulu zomwe zingasankhidwe m'malo mwa ma valve a chipata ndi ma valve a gulugufe. Ma valve a mpira ndi abwino kwambiri potseka mwachangu, kotala la ma payipi m'mapaipi ang'onoang'ono. Ma valve a gulugufe ndi chisankho chotsika mtengo cha mapaipi akuluakulu.

Kusankha pakati pa ma valve awa kumadalira ntchito yonse.valavu ya mpiraNdi njira yabwino kwambiri yogwiritsira ntchito chitoliro chilichonse chofika mainchesi 4 m'mimba mwake. Chimagwiritsa ntchito mpira wachitsulo wokhala ndi dzenje mkati mwake. Kutembenuza chogwirira cha madigiri 90 kumagwirizanitsa dzenje ndi chitoliro kuti chiziyenda bwino kapena kuchitembenuza motsutsana ndi madzi kuti chizimitse kwathunthu. Izi zimapangitsa kuti chizigwira ntchito mwachangu kwambiri, ndipo mutha kuwona malo ake pongoyang'ana chogwiriracho. Chimakhalanso bwino kwambiri pakuchepetsa madzi kuposa valavu ya chipata. Pa mapaipi akuluakulu kwambiri, monga chitoliro chamadzi cha mainchesi 12, valavu ya chipata imakhala yayikulu komanso yokwera mtengo. Apa ndi pomwevalavu ya gulugufendi yabwino kwambiri. Imagwiritsa ntchito diski yopyapyala pakati pa chitoliro chomwe chimazungulira madigiri 90 kuti chitseguke kapena kutsekedwa.
