Kodi Valavu ya Chipata ndi Chiyani mu Mapaipi: Ntchito, Kuyerekeza, ndi Opanga Apamwamba

Kodi Valavu ya Chipata ndi Chiyani mu Mapaipi?

A valavu ya chipatandi gawo lofunikira kwambiri mu mapaipi ndi mapaipi, lopangidwa kuti liziwongolera kuyenda kwa madzi kapena mpweya mwa kukweza kapena kutsitsa "chipata" chathyathyathya (chokhala ndi diski yooneka ngati wedge kapena yofanana) mkati mwa valavu. Chipatacho chikatsegulidwa bwino, chimabwerera m'mbuyo kupita ku bonnet ya valavu, zomwe zimapangitsa kuti madzi aziyenda bwino. Chikatsekedwa, chipatacho chimatseka mipando m'thupi la valavu, ndikuletsa kuyenda konse. Mavalavu a chipata amagwiritsidwa ntchito makamaka pamapulogalamu otsegula/otsekam'malo molamulira kayendedwe ka madzi, zomwe zimapangitsa kuti zikhale zoyenera kwambiri pamakina omwe amafunika kutsekedwa kwathunthu kapena kutsekedwa kwathunthu.

Zinthu Zofunika Kwambiri pa Ma Valves a Chipata

- Kapangidwe Kolimba:Yopangidwira malo omwe ali ndi mphamvu yamagetsi komanso kutentha kwambiri.

- Kukana Kuyenda Kochepa:Kutsika kochepa kwa mphamvu ya mpweya ikatsegulidwa kwathunthu.

- Kuyenda kwa Mayendedwe Awiri:Ikhoza kuyikidwa mbali iliyonse ya kayendedwe ka madzi.

- Zipangizo Zodziwika:Mkuwa, chitsulo chosungunuka, chitsulo chosapanga dzimbiri, kapena PVC, kutengera momwe zimagwiritsidwira ntchito.

Ma Valves a Chipata ndi Ma Valves a Mpira: Kusiyana Kwakukulu

Ngakhale ma valve onse a chipata ndi ma valve a mpira amagwira ntchito ngati zida zowongolera kuyenda kwa madzi, mapangidwe awo ndi momwe amagwiritsidwira ntchito zimasiyana kwambiri:

Nthawi Yosankha Valavu ya Chipata:

- Kwa machitidwe omwe amafuna madzi okwanira kapena osagwiritsidwa ntchito kawirikawiri (monga mitsinje ikuluikulu yamadzi).

- M'malo otentha kwambiri kapena opanikizika kwambiri.

Nthawi Yosankha Valavu ya Mpira:

- Kwa machitidwe omwe amafunika kugwira ntchito pafupipafupi kapena kusintha kayendedwe ka madzi.

- Mu mapaipi amadzi kapena mipanda ya gasi m'nyumba.

Opanga Ma Vavu a Chipata: Osewera Ofunika

Ma valve a pachipata amapangidwa ndi opanga ambiri padziko lonse lapansi komanso m'madera osiyanasiyana. Miyezo yaubwino, kusankha zinthu, ndi ziphaso (monga ISO, ANSI, API) ndi zinthu zofunika kwambiri posankha wogulitsa.

Opanga Ma Vavu Otsogola a Chipata

1. Emerson (ASCO):Amadziwika ndi ma valve apamwamba kwambiri m'mafakitale okhala ndi uinjiniya wolondola.

2. Kampani ya Crane:Amapereka ma valve osiyanasiyana kuti agwiritsidwe ntchito m'malo ovuta.

3. AVK International:Amadziwika bwino ndi ma valve ogawa madzi ndi gasi.

4. Velan Inc.:Mtsogoleri wapadziko lonse lapansi pa ma valve ogwira ntchito bwino.

5. Kampani ya NSW:Wopanga Ma Vavu Waluso ndi Fakitale ya Ma Vavu a Mpira, Fakitale ya Ma Vavu a Chipata, Fakitale ya Ma Vavu a Chongani/Globe/Plug/Butterfly ndi Fakitale ya Pneumatic actuator

Makampani Opanga Ma Valve a Chipata cha China: Malo Ogulitsira Padziko Lonse

China yakhala ngati wosewera wamkulu pakupanga ma valve a zipata, kuphatikizakugwiritsa ntchito bwino ndalamandi miyezo yabwino yowongolera. Ubwino waukulu ndi monga:

- Mitengo Yopikisana:Ndalama zochepa zogulira antchito ndi zopanga poyerekeza ndi misika ya kumadzulo.

- Kukula:Kutha kupanga mabuku ambiri kuti agawidwe padziko lonse lapansi.

- Kupita Patsogolo kwa Ukadaulo:Kugwiritsa ntchito makina a CNC ndi macheke aukadaulo wokha.

- Utsogoleri wa Kutumiza Zinthu Kunja:Mitundu yaku China mongaSUFA, Valavu ya NSWndiYuanda Valveamagwiritsidwa ntchito kwambiri pochiza madzi, mafuta ndi gasi, komanso machitidwe a HVAC padziko lonse lapansi.

Zinthu Zofunika Kuziganizira Mukagula ku China:

- Tsimikizani ziphaso (monga ISO 9001, CE, API).

- Pemphani malipoti oyesera zinthu (MTRs) pa ntchito zofunika kwambiri.

- Gwirizanani ndi ogulitsa odalirika kuti mupewe zinthu zabodza.

Mapeto

Ma valve a pachipata akadali ofunikira kwambiri m'makina a mapaipi kuti azimitsidwe bwino m'malo ovuta. Ngakhale ma valve a mpira amapambana pakugwiritsa ntchito zinthu zosiyanasiyana komanso mosavuta, ma valve a pachipata ndi ofanana ndi omwe amagwiritsidwa ntchito ndi mphamvu zambiri komanso kuthamanga kwa madzi. Popeza China ikulamulira gawo lapadziko lonse lapansi lopanga ma valve, ogula amatha kupeza ma valve apamwamba kwambiri pamitengo yopikisana - bola ngati apereka makasitomala ovomerezeka komanso kuwunika bwino kwambiri.

Pomvetsetsa mphamvu za ma valve a pachipata ndi opanga awo, akatswiri a mapaipi amatha kupanga zisankho zolondola zogwirizana ndi zosowa za makina awo.
