Kodi mungasankhe bwanji valavu yolondola?

M'magulu osiyanasiyana amadzimadzi, chekeni ndi zinthu zazikulu kuti muchepetse kusunthira kwa media ndipo amagwiritsidwa ntchito kwambiri m'madzi ndi ngalande, mafuta amagetsi, mafakitale ena. Ngakhale valavu ya cheke imawoneka yosavuta posankha, posankha zenizeni, ngati malo ogwirira ntchito, malo okhazikitsa kapena mikhalidwe yapakatikati sanyalanyazidwa, ndikosavuta kuyambitsa zolephera kapena kuwonongeka kwa dongosolo.

Kwa ogwira ntchito makampani ogwirira ntchito, kumvetsetsa bwino mfundo zogwirira ntchito ndi malingaliro a cheke sizingakulitse moyo wautumiki wa zida, komanso kuchepetsa ndalama zokonzanso. Otsatirawa afotokoza momwe angasankhire mwasayansi oyenera kuchokera pazigawo zingapo.

1. Vonjatsani zofunikira

Gawo loyamba posankha aChongani valavundikumvetsetsa magawo oyambira a sing'anga. Kuphatikiza:

Mtundu wamadzimadzi (madzi oyera, mafuta, nthunzi, zamadzimadzi, etc.)

Kutentha kwapakatikati (kutentha kochepa, kutentha kwapakatikati kapena kutentha kwambiri)

Kukakamizidwa (kaya ndi dongosolo lambiri)

Kaya zili ndi tinthu tokha (monga chimbudzi, matope matope)

Zinthu zosiyanasiyana zogwirira ntchito zimakhala ndi zofunikira zosiyanasiyana kapangidwe kake ka Vevu. Mwachitsanzo, kutentha kwambiri komanso njira zopindika kwambiri, zisindikizo za mphira ziyenera kupewedwa, ndipo zisindikizo zachitsulo zimayang'ana patsogolo.

Fuose mtundu woyenera woyenera

Chongani MavalveItha kugawika mitundu yotsatirayi malinga ndi kapangidwe kake:

Valani valavu: Yoyenera kukhazikitsa mapaipi opingasa, oyenera nthawi zambiri ndi okwera kwambiri komanso kutseka pafupipafupi komanso kutseka. Kapangidwe kake kali kopindika, koma kukhazikitsidwa kwa kukhazikitsa ndikokhazikika.

Swing Check Valve: Kutha kwamphamvu kwambiri, kutaya pang'ono, koyenera mapaipi akati komanso ochepa.

Freefffly Check Vavve: Kukula kochepa, kulemera kopepuka, kugwiritsidwa ntchito kwambiri m'magulu okhala ndi malo okhazikitsa, monga kumanga madzi amadzi.

Vesi la mpira: Woyenerera mapaipi okhala ndi tinthu tating'onoting'ono kapena ma vidio, omwe amatha kupewa blockge.

Onani maupangiri ophatikizika: Opangika makamaka pamapampu amadzi, amatha kuchepetsa mphamvu yamadzi pamndandanda.

Mukamagula, muyenera kusankha mtundu wokhala ndi maziko oyenera kutengera kutengera kwa dongosolo, malo okhazikitsa ndi mawonekedwe apakatikati.

3.Pawunikidwe pazinthu ndi zida zokopa

Zipangizo zazikulu zofufuzira mavu ambiri nthawi zambiri zimaphatikizira chitsulo, chitsulo cha kaboni, chitsulo chosapanga dzimbiri, ndi zina zambiri posankha, muyenera kuganizira za kutentha kwake:

Makina amadzi wamba nthawi zambiri amagwiritsa ntchito chitsulo kapena mkuwa

Zakumwa zakuthengo zimatha kugwiritsa ntchito chitsulo chosapanga dzimbiri

Katundu wachitsulo kapena alloy mawonekedwe amalimbikitsidwa kuti azipanikizika kwambiri komanso kutentha kwambiri

Kuphatikiza apo, zinthu zokopa zopindika za chekeyo zimakhudza mwachindunji chipilala ndi moyo wa ntchito. Zisindikizo zofewa ndizoyenera kwa media yoyera kutentha, pomwe Zisindikizo zachitsulo ndizoyenera kutentha kwambiri kapena kudetsedwa

4.Chamarf.

Chongani MavalveNthawi zambiri amakhala ndi zofunika kwambiri pakuwongolera. Kukhazikitsa kolakwika kumapangitsa valavu kuti isasokoneze ndi kuyandikira kwambiri. Malangizo otsatirawa ayenera kumvetsetsa mukagula:

Kodi pali malo okwanira kukhazikitsa thupi la valavu

Kodi chiwonetsero cha mapaipi chimalola kusankha mtundu wina (monga mtundu wokweza ukhoza kukhazikitsidwa kokha)

Ndizosavuta kuyang'ana mtsogolo ndi kukonza

Ngati malo ali ochepa, ofukula kapena owoneka bwino

5. Kuganizira zachuma komanso chitsimikiziro cha mtundu

Ngakhale valavu ya cheke ndi gawo laling'ono, kamodzi kulephera kumachitika, zingayambitse dongosolo Reflux, kuwonongeka kwa zida kapena kukhazikika. Chifukwa chake, pogula, simungathe kuyang'ana pamtengo. Malangizo otsatirawa akuyenera kuyang'ana pa:

Kaya malonda adutsa mukuyendera bwino

Kaya wogulitsa amapereka chithandizo chosankha

Kaya valve ndi njira yokonzanso zoyembekezera

Kusankha wopanga valavu yokhala ndi gawo lokhazikika komanso thandizo laukadaulo lidzachepetsa kwambiri ngozi zomwe pambuyo pake zimachita.

Pogula mavavu, ndikofunikira kuti musankhe ndikugula yoyenera

Kusankhidwa kwa mavesi kumawoneka kosavuta, koma kumafuna mbali zambiri za chiweruzo chaukadaulo. Kwa ogula makampani, kumvetsetsa mtundu wake, zochitika zomwe zimagwiritsidwa ntchito, komanso ntchito yoyambayo ndi gawo loyamba kuti muwonetsetse dongosolo la dongosololi. Ndikulimbikitsidwa kulumikizana mokwanira ndi mainjiniya panthawi yosankhidwa, ndipo ngati kuli kotheka, kulumikizana ndi wopanga kapena malingaliro.

Takhala tikulingalira za mavesi a mafakitale a mafakitale kwa zaka zambiri, ndipo zopangidwa zathu zimaphimba mitundu yosiyanasiyana ya mavesi, othandizira, chitsogozo chaukadaulo ndi ntchito kukhazikitsa kukhazikitsa. Ngati muli ndi mafunso panjira yosankha, chonde khalani omasukaLumikizanani nafe.
