Valavu yowona ya mpira wolumikizana ndi valavu ya magawo atatu yokhala ndi ulusi wolumikizana. Kapangidwe kameneka kamakulolani kuti muchotse thupi lonse lapakati valavu kuti mugwiritse ntchito kapena kusinthana popanda kudula chitoliro.

Ichi ndi chimodzi mwazinthu zomwe ndimakonda kufotokozera zibwenzi monga Budi ku Indonesia. Thevalavu ya mpira wowonasi gawo chabe; ndiyothetsa mavuto. Kwa aliyense wa makasitomala ake mu processing mafakitale, mankhwala madzi, kapena aquaculture, downtime ndiye mdani wamkulu. Kukhoza kuchitakukonza mu miniti, osati maola, ndi mwayi wamphamvu. Kumvetsetsa ndikugulitsa izi ndi njira yomveka bwino yopangira mwayi wopambana pomwe makasitomala ake amasunga ndalama ndikumuwona ngati katswiri wofunikira.

Kodi pali kusiyana kotani pakati pa valavu ya mpira ndi valavu ya mpira?

Mukuwona valavu ya 2-piece ndi valve yowona. Onse awiri amasiya madzi, koma imodzi imawononga ndalama zambiri. Mukudabwa ngati mtengo wowonjezerawo ndi woyenera pa polojekiti yanu.

Kusiyana kwakukulu ndikukonza mumzere. Vavu yokhazikika ya mpira ndiyokhazikika, pomwe thupi lenileni la valavu ya mpira limatha kuchotsedwa papaipi kuti likonzedwe pambuyo pa kukhazikitsa.

Funso ili likufika pamalingaliro amtengo wapatali. Ngakhale kuti onsewa ndi mitundu ya ma valve a mpira, momwe amalumikizirana ndi dongosolo amasintha zonse zokhudzana ndi ntchito yawo yayitali. Valavu yokhazikika ya mpira, kaya 1-chidutswa kapena 2-chidutswa, imalumikizidwa mwachindunji ndi chitoliro. Akamamatidwa kapena kulumikizidwa mkati, amakhala gawo la chitoliro. Mapangidwe enieni a mgwirizano ndi osiyana. Zimakhala ngati chigawo chochotsedwa. Kwa makasitomala a Budi, kusankha kumabwera ku funso limodzi: Kodi nthawi yopuma ndi yotani?

Tiyeni tifotokoze:

Kodi valavu ya mpira wa mgwirizano imagwira ntchito bwanji?

Mukuwona mtedza waukulu pa valve koma simukumvetsa momwe zimagwirira ntchito. Izi zimapangitsa kuti zikhale zovuta kufotokozera phindu kwa makasitomala anu, omwe amangowona valavu yamtengo wapatali.

Zimagwira ntchito pogwiritsa ntchito magawo atatu: tailpieces ziwiri zomwe zimagwirizanitsa ndi chitoliro ndi thupi lapakati. Mtedza waumodzi umapindikira pazidutswa ta mchira, ndikumangirira thupi motetezedwa ndi mphete za O.

Kapangidwe kake ndi kodabwitsa m'kuphweka kwake. Nthawi zambiri ndimatenga imodzi kuti ndiwonetse Budi momwe zidutswazo zimayenderana. Kumvetsetsa zimango kumapangitsa mtengo wake kumveka bwino nthawi yomweyo.

The Components

1. Central Body:Ili ndiye gawo lalikulu lomwe lili ndi mpira, tsinde, ndi chogwirira. Imagwira ntchito yeniyeni yowongolera kuyenda.
2. Zamchira:Izi ndi nsonga ziwiri zomwe zimakhala zosungunulira mpaka kalekale (zomatira) kapena zomangika pamapaipi. Iwo ali ndi flanges ndi grooves kwa O-mphete.
3. Mtedza wa Union:Izi ndi zazikulu, mtedza wa ulusi. Iwo amatsetsereka pa tailpieces.
4. O-mphete:Mphete za mphirazi zimakhala pakati pa thupi lapakati ndi m'mbuyo, zomwe zimapangitsa kuti chisindikizo chikhale cholimba, chosakhala ndi madzi chikaunikizidwa.

Kuti muyike, mumamatira zitsulo zam'mbuyo pa chitoliro. Kenaka, mumayika thupi lapakati pakati pawo ndikungolimbitsa mtedza wa mgwirizanowu ndi dzanja. Mtedza umakanikiza thupi motsutsana ndi O-rings, kupanga chisindikizo chotetezeka, chosadukiza. Kuti muchotse, mumangosintha ndondomekoyi.

Kodi cholinga cha trunnion mu valavu ya mpira ndi chiyani?

Mumamva mawu oti "trunnion mounted" ndikuganiza kuti akugwirizana ndi "mgwirizano weniweni." Chisokonezo ichi ndi owopsa chifukwa ndi mbali zosiyana kwambiri za ntchito zosiyana kwambiri.

Trunnion alibe chochita ndi mgwirizano. Trunnion ndi pini yamkati yomwe imathandizira mpira kuchokera pamwamba ndi pansi, yomwe imagwiritsidwa ntchito muzitsulo zazikulu kwambiri, zothamanga kwambiri, osati ma valve a PVC.

Iyi ndi mfundo yofunikira kwambiri yomwe ndimapereka kwa onse omwe timagwira nawo ntchito. Kusokoneza mawuwa kungayambitse zolakwika zazikulu zamatchulidwe. "Mgwirizano" amatanthauzamtundu wa kugwirizana kwakunja, pamene "trunnion" amatanthauzamakina othandizira mpira wamkati.

Mavavu ambiri a PVC a mpira, kuphatikiza zitsanzo zathu za Pntek, amagwiritsa ntchito mapangidwe a "mpira woyandama" pomwe kukakamiza kumakankhira mpira kumpando wakumunsi. A trunnion ndi yogwiritsa ntchito monyanyira kuposa momwe mungasamalire madzi.

Kodi vavu ya mgwirizano ndi chiyani?

Mukumva makontrakitala akufunsa "valavu ya mgwirizano" ndipo mukuganiza kuti akutanthauza valavu ya mpira. Kupanga lingaliro kungatanthauze kuyitanitsa chinthu cholakwika ngati angafunike ntchito ina.

"Valovu ya mgwirizano" ndi liwu lodziwika bwino la valavu iliyonse yomwe imagwiritsa ntchito kulumikizana kwa mgwirizano pakuchotsa pamzere. Ngakhale mtundu wodziwika bwino ndi True Union Ball Valve, mitundu ina ilipo, mongaTrue Union Check Valves.

Mawu oti "mgwirizano" amafotokoza mawonekedwe a kulumikizana, osati ntchito ya valve. Ntchito ya valavu imatsimikiziridwa ndi makina ake amkati-mpira wowongolera / kuzizimitsa, njira yowunika kuteteza kubwerera, ndi zina zotero. Ku Pntek, timapanganso True Union Check Valves. Amapereka phindu lofanana ndendende ndi mavavu athu enieni a mpira: kuchotsa mosavuta ndi kusamalira. Ngati valavu yoyang'ana iyenera kutsukidwa kapena kasupe m'malo mwake, mukhoza kuchotsa thupi popanda kudula chitoliro. Pamene kasitomala afunsa gulu la Budi "valavu ya mgwirizano," ndi mwayi waukulu wosonyeza luso pofunsa funso losavuta lotsatila: "Zabwino. Kodi mukufunikira valavu ya mpira wa mgwirizano kuti muwonetsere / kuzimitsa, kapena valavu yoyang'anira mgwirizano kuti mupewe kubwereranso?" Izi zimamveketsa dongosolo ndikumanga chikhulupiriro.

Mapeto

Valavu yeniyeni ya mpira imalola kuti ma valve achotsedwe popanda kudula chitoliro. Chofunikira ichi chimapulumutsa nthawi, ntchito, ndi ndalama zambiri pamakina aliwonse
