Kuwulula Kusiyana: Mpira vs. Valvu Yoyang'anira - Ndi Uti Umene Umalamulira Kwambiri

Valavu ya Mpira vs. Valavu Yowunikira - Kuyerekeza Kothandiza

Ngati mudagwirapo ntchito pa makina opachikira mapaipi, mwina mudakumanapo ndi funso ili:Kodi ndiyenera kugwiritsa ntchito valavu ya mpira kapena valavu yowunikira?Amaoneka mosiyana, amagwira ntchito mosiyana, ndipo amakwaniritsa zolinga zosiyanasiyana — komabe anthu ambiri amawasokoneza.

Ndikukumbukira ndikuthandiza fakitale yaying'ono yoyeretsera madzi otayidwa zaka zingapo zapitazo. Anayika valavu yoyezera komwe kumafunika valavu ya mpira, ndipo zotsatira zake zinali kutaya mphamvu nthawi zonse. Cholakwika chaching'ono chimenecho chinawawonongera masiku atatu othetsa mavuto. Choncho tiyeni tikonze zinthu kamodzi kokha.

Kodi Valavu Iliyonse Imakhala Yapadera Bwanji?

Valavu ya Mpira - Chowongolera Mayendedwe a Manual

Valavu ya mpira imagwiritsa ntchito mpira wopanda kanthu wokhala ndi dzenje pakati. Mukatembenuza chogwirira madigiri 90, dzenjelo limagwirizana ndi chitoliro (kutsegula) kapena kulitseka (kutseka). Ndicho chokha — chosavuta, chachangu, komanso chodalirika.

Kumene kumawala:

• Kutseka kwadzidzidzi (kotala la kutembenuka = ​​kuyima nthawi yomweyo)
• Mizere ya gasi kapena mafuta opanikizika kwambiri
• Mapulogalamu omwe mukufuna kusindikizidwa mwamphamvu ngakhale patatha miyezi ingapo osagwiritsa ntchito

Nkhani yeniyeni: Ma valve a mpira si abwino kwambiri pobowola bwino. Ngati muyesa kuwasunga otseguka kwa nthawi yayitali, mpandowo ukhoza kutha mosagwirizana.

Valavu Yoyang'anira - Woyang'anira Wodziyimira Payokha

Valavu yoyezera ilibe chogwirira. Imatseguka madzi akamayenda patsogolo, ndipo imatseka yokha madzi akabwerera m'mbuyo kapena kuyima. Palibe chifukwa chochitirapo kanthu ndi munthu.

Kumene kumawala:

• Mizere yotulutsira madzi pampu (imaletsa kubwerera kwa madzi pamene pampu yasiya kugwira ntchito)
• Mapampu a Sump m'zipinda zapansi
• Makina a nthunzi kapena ma condensate komwe kuyenda kwa madzi kumbuyo kungawononge zida

Chomwe chimakwiyitsa anthu: Ma valve owunikira amatha "kutseka" ngati madziwo asiya mwadzidzidzi. Phokoso lomveka bwino si phokoso lokha - limatha kuswa malo olumikizira mapaipi pakapita nthawi.

Valavu ya Mpira vs. Valavu Yowunikira: Kusiyana Kwakukulu

1. Magwiridwe antchito ndi kapangidwe:

- Ma Vavu a Mpira: Yodziwika ndi mpira wozungulira wokhala ndi bore, ma valve a mpira amawongolera kuyenda kwa mpirawo pozungulira mpirawo madigiri 90. Amapereka kutseka mwachangu, kutsika pang'ono kwa mphamvu, komanso kuwongolera kuyenda kwa mpweya mbali zonse ziwiri. Yabwino kwambiri poyatsa/kuzima m'mafakitale amafuta, gasi, ndi mankhwala.

- Ma Valuvu Oyang'anira: Yopangidwa kuti ilole kuyenda kwa madzi kuyenda mbali imodzi, ma valve owunikira amaletsa kuyenda kwa madzi kubwerera m'mbuyo. Amasowa mphamvu yowongolera ndi manja ndipo amadalira mphamvu yamadzi kuti atsegule/kutseka. Amagwiritsidwa ntchito kwambiri m'makina amadzi, mapampu, ndi HVAC.

2. Kugwira Ntchito Mwanzeru:

- Ma valve a mpira amagwira ntchito bwino kwambiri m'malo otentha kwambiri komanso opanikizika chifukwa cha kutseka kwawo kolimba.

- Onetsetsani kuti ma valve akuyang'anira chitetezo m'makina omwe kupewa kubwerera kwa madzi ndikofunikira koma kumafuna kusamaliridwa kochepa.

3. Mapulogalamu:

- Ma valve a mpira ndi omwe amalamulira kwambiri pazochitika zotseka ndi zotsekereza.

- Onetsetsani kuti ma valve akuwala m'makina omwe amafunikira kupewa kubwereranso kwa madzi.

Mbali ndi Mbali: Tebulo Loyerekeza Mwachangu

Mitundu Yodziwika Yomwe Mudzakumane Nayo

Kusintha kwa ma valve a mpira

• Mpira woyandama: Yodziwika kwambiri, yotsika mtengo, imagwira ntchito bwino pa mphamvu yochepa mpaka yapakati.
• Trunnion yokwera: Thandizo lowonjezera la kuthamanga kwa magazi (taganizirani mapaipi amafuta).
• V-port: Mpira wapadera wokhala ndi notch yooneka ngati V — umalola kuwongolera kayendedwe ka madzi pang'ono, osati kungoyatsa/kuzima kokha.

Yang'anani kusintha kwa ma valavu

• Kuyang'ana kozungulira: Chophimba cholumikizidwa chimatseguka. Chimagwira ntchito bwino kwambiri m'mapaipi opingasa.
• Kuyang'ana chikwezero: Disiki imakwezedwa mmwamba ndi pansi. Yabwino pa nthunzi kapena madzi othamanga kwambiri.
• Mbale ziwiri / cheke cha wafer: Yopapatiza kwambiri, imakwanira pakati pa ma flange. Yodziwika bwino m'malo opapatiza.

Ndinawonapo valavu yowunikira mbale ziwiri itayikidwa molunjika mu fakitale ya mankhwala - ndipo idagwira ntchito bwino chifukwa kapangidwe kake kothandizidwa ndi masika kankatha kuthana ndi mphamvu yokoka. Koma kuyang'ana kokhazikika kwa swing kukanalephera pamenepo. Zambiri ndizofunikira.

Momwe Mungasankhire Valavu Yoyenera (ndi Wopereka)

Musanagule, dzifunseni mafunso atatu:

1. Kodi ndikufunika chitetezo chowongolera ndi manja kapena chodzitetezera chokha?

   • Ngati mukufunasiyani kuyenda kwa madzi ngati pakufunika→ valavu ya mpira
   • Ngati mukufunalekani kuyenda mobwerera m'mbuyo zokha→ valavu yoyezera
   • Nthawi zina mumafunika zonse ziwiri motsatizana — inde, ndizofala.

2. Kodi kuthamanga kwanga, kutentha kwa thupi langa, ndi madzi anga ndi otani?

   • Mankhwala owononga? Gwiritsani ntchito chitsulo chosapanga dzimbiri kapena ma valve a mpira okhala ndi PTFE.
   • Madzi otayira akuda? Chotsukira chopangidwa ndi rabara chingathe kupirira kuposa chachitsulo.

3. Kodi ndani amene angandipatse?

   • Funsani malipoti a mayeso (kuyesa kuthamanga kwa mpweya, kuyeza kutayikira kwa madzi pampando).
   • Onetsetsani ngati ali ndi kukula kofanana kapena akufunika maoda apadera — nthawi yopezera zinthu imawononga mapulojekiti.
   • Yang'anani ISO 9001, koma musapembedze ziphaso. Ndaona ogulitsa ovomerezeka akupereka zinthu zoipa. Funsani maumboni ochokera kumakampani ofanana.

Nkhani Yachidule Yokhudza Kusankha kwa Ogulitsa

Kasitomala wanga ankafuna ma valve 20 a mainchesi 6 kuti agwiritse ntchito pompu yothirira. Mtengo wotsika kwambiri unachokera kwa wogulitsa wosadziwika pa intaneti. Anasunga 30% pasadakhale - koma patatha miyezi itatu, ma valve awiri sanatseke. Madzi anaswa nangula wa konkire. Ndalama zokonzera zinawononga ndalama zokwana khumi.

Tsopano nthawi zonse ndimanena kuti:Mtengo ndi zomwe mumalipira; mtengo ndi zomwe mumapeza.Wogulitsa wodalirika adzakupatsani ziphaso zofunikira, makanema oyesera, ndi chitsimikizo chomveka bwino. Musasiye zimenezo.

Chigamulo Chomaliza - Ndi Chiti "Chimene Chimalamulira Wamkulu"?

Palibe. Yankho lenileni ndi limenelo.

• Ma valve a mpira ndi mafumu a kutseka kwa manja.
• Ma valve oyesera ndi ngwazi zopewera kubwerera kwa madzi.

Simungasinthe chimodzi ndi china. Kusankha koyenera kumadalira kwathunthu zosowa za makina anu. Ngati mukufuna ntchito zonse ziwiri, ikani zonse ziwiri — ingosiyani malo okwanira okonzera.
