Kodi Valavu ya Gulugufe Yopatukana Katatu ndi Chiyani? Mosiyana ndi Mtundu Wozungulira

Kodi Valavu ya Gulugufe Yopatukana Katatu ndi Chiyani: Kusiyana Pakati pa Valavu ya Gulugufe Yozungulira ndi Yogwira Ntchito Kwambiri

Mu gawo la ma valve a mafakitale, ma valve a gulugufe amagwiritsidwa ntchito kwambiri polamulira madzi chifukwa cha kapangidwe kake kakang'ono komanso kutsegula ndi kutseka mwachangu. Ndi chitukuko cha ukadaulo, kapangidwe ka ma valve a gulugufe kakhala kokonzedwa nthawi zonse, zomwe zimapangitsa mitundu yosiyanasiyana mongavalavu ya gulugufe yapakati, valavu ya gulugufe iwiri yosiyanandivalavu ya gulugufe yozungulira katatuNkhaniyi iyamba ndi mfundo za kapangidwe kake, kuyerekeza magwiridwe antchito ndi malingaliro osankha, ndikusanthula mozama zabwino zazikulu zavalavu ya gulugufe yozungulira katatu, ndi kufufuza momwe mungasankhire zinthu zapamwambaopanga mavavu a gulugufendiogulitsa.

Kugawa ndi Makhalidwe a Ma Valves a Gulugufe

 1. Valavu ya Gulugufe Yozungulira

 - Makhalidwe a kapangidwe kake: Mbale ya valavu ndi yolumikizana ndi tsinde la valavu, pamwamba pake potsekerapo pamakhala pofanana, ndipo mpando wa valavu nthawi zambiri umapangidwa ndi zinthu zofewa (monga rabala).

- Ubwino: Mtengo wotsika, kapangidwe kosavuta, koyenera kupsinjika pang'ono komanso kutentha kwabwinobwino.

- Zoyipa: Kukana kwakukulu kwa kukangana, ndipo magwiridwe antchito otsekera amachepa ndi kuwonjezeka kwa kutentha ndi kupanikizika.

- Zochitika zogwiritsira ntchito: mikhalidwe yogwirira ntchito yosautsa monga kuyeretsa madzi, HVAC, ndi zina zotero.

2. Valavu ya Gulugufe Yaiwiri Yozungulira

- Makhalidwe a kapangidwe kake:

- Kusasinthika koyamba: tsinde la valavu limapatuka pakati pa mbale ya valavu kuti lichepetse kukangana kwa kutsegula ndi kutseka.

- Kusasinthasintha kwachiwiri: pamwamba pa chitseko cha valavu pamakhala chosiyana ndi mzere wapakati wa payipi kuti pakhale chitseko chosakhudzana ndi kukhudzana.

- Ubwino: mphamvu yaying'ono yotsegulira ndi kutseka, magwiridwe antchito abwino otsekera kuposa valavu ya gulugufe yapakati.

- Zoyipa: zinthu zotsekera zimatha kukalamba kutentha kwambiri komanso kupanikizika kwambiri.

- Zochitika zogwiritsira ntchito: mapaipi apakati ndi otsika mphamvu m'mafakitale a mafuta ndi mankhwala.

3. Valavu ya Gulugufe Yozungulira Katatu

- Makhalidwe a kapangidwe kake:

- Kusasinthika koyamba: tsinde la valavu limapatuka pakati pa mbale ya valavu.

- Kusasinthasintha kwachiwiri: malo otsekera mbale ya valavu amapatuka kuchoka pakati pa payipi.

- Kusasinthasintha kwachitatu: kapangidwe ka ngodya ya pamwamba pa koni yotsekera kamapangitsa kuti ikhale yolimba kwambiri.

- Ubwino:

- Kutsegula ndi kutseka kwa zero: Mbale ya valavu ndi mpando wa valavu zimalumikizana pokhapokha zikatsekedwa, zomwe zimatalikitsa moyo wa ntchito.

- Kutentha kwambiri komanso kukana kuthamanga kwambiri: Zisindikizo zachitsulo zimatha kupirira kutentha kwambiri kuposa 400℃ ndi milingo ya Class 600.

- Kusindikiza mbali ziwiri: Yoyenera kugwira ntchito movutikira pomwe sing'anga imayenda mbali zonse ziwiri.

- Zochitika zogwiritsira ntchito: Makina ofunikira okhala ndi kutentha kwambiri komanso kuthamanga kwambiri monga mphamvu, petrochemical, ndi LNG.

4. Vavu ya Gulugufe Yapamwamba Kwambiri

- Tanthauzo: Kawirikawiri imatanthauza valavu ya gulugufe yokhala ndi mawonekedwe awiri kapena atatu, omwe ali ndi mphamvu yochepa, kutseka kwakukulu komanso moyo wautali.

- Ubwino waukulu: Ikhoza kusintha ma valve ena a chipata ndi ma valve a mpira ndikuchepetsa mtengo wa makina a mapaipi.

Chifukwa chiyani valavu ya gulugufe ya eccentric katatu ndiyo chisankho choyamba chamakampani

 1. Kusanthula ubwino wa kapangidwe kake

- Kapangidwe ka chisindikizo cholimba chachitsulo: Yopangidwa ndi chitsulo chosapanga dzimbiri, chitsulo chosakanikirana ndi zinthu zina, imapirira dzimbiri komanso kusweka.

- Malo otsekera okhala ndi mawonekedwe ozungulira: kukhudzana pang'onopang'ono kumapangidwa potseka, ndipo chisindikizocho chimakhala cholimba.

- Kapangidwe ka chitetezo cha moto: mitundu ina imakwaniritsa satifiketi ya API 607 ​​​​yosapsa ndi moto ndipo ndi yoyenera malo oopsa.

2. Kuyerekeza ndi valavu ya gulugufe iwiri yosiyana

3. Milandu yogwiritsira ntchito mafakitale

- Makampani opanga magetsi: imagwiritsidwa ntchito mu makina ophikira madzi a boiler, yolimba ku nthunzi yotentha kwambiri.

- Mankhwala a Petrochemical: Lamulirani zinthu zowononga m'magawo oyambitsa kusweka kwa zinthu.

- Kusungira ndi mayendedwe a LNG: Sungani kudalirika kotseka pansi pa kutentha kochepa kwambiri.

Momwe mungasankhire opanga ndi ogulitsa ma valavu apamwamba kwambiri a gulugufe 

1. Yang'anani mphamvu zaukadaulo

- Ma Patent ndi ziphaso: Ikani patsogoloopangaomwe ali ndi ukadaulo wa ma valve a gulugufe atatu odziwika bwino ndipo ali ndi satifiketi ya API 609 ndi ISO 15848.

- Zotheka kusinthaKodi mungapereke ma valve okhala ndi kukula kosakhala kwachizolowezi komanso zipangizo zapadera (monga Monel, Inconel).

2. Yang'anani kuwongolera khalidwe la kupanga

- Kuyesa zinthuMalipoti ofunikira (monga miyezo ya ASTM) amafunika.

- Kuyesa magwiridwe antchitoKuphatikizapo mayeso otseka ndi mayeso a moyo (monga ma 10,000 otseguka ndi otseka popanda kutuluka).

3. Yang'anani mtengo ndi kuthekera kotumizira

- Ubwino wa mafakitale aku China:

- Mpikisano pamitengoChitchainaogulitsa mavavu a gulugufeamadalira kupanga kwakukulu, ndipo mtengo wake ndi wotsika ndi 30%-50% poyerekeza ndi wa mitundu yaku Europe ndi America.

- Kutumiza mwachangu: Kuchuluka kokwanira kwa zinthu zokhazikika, zomwe zimathandiza milungu iwiri kapena inayi yotumizira.

4. Yang'anani ntchito yogulitsa pambuyo pogulitsa

- Perekani malangizo okhazikitsa pamalopo, kukonza nthawi zonse komanso kupereka zida zina.

Zochitika zamtsogolo za ma valve a gulugufe amitundu itatu

1. Kusintha kwanzeru: Masensa ophatikizidwa ndi ma module a IoT kuti aziwunika momwe valavu ilili nthawi yeniyeni.

2. Kugwiritsa ntchito zinthu zoyera zachilengedwe: Gwiritsani ntchito kapangidwe kopanda kutayikira kwa madzi komanso mpweya woipa wochepa (chitsimikizo cha ISO 15848).

3. Kukula kwa gawo la kutentha kochepa kwambiri: Imagwira ntchito pamavuto ogwirira ntchito monga hydrogen yamadzimadzi (-253℃) ndi helium yamadzimadzi.

Mapeto 

Valavu ya gulugufe yozungulira katatuyakhala valavu yokondedwa kwambiri ya mapaipi a mafakitale otentha kwambiri komanso opanikizika kwambiri chifukwa cha kapangidwe kake kolimba kachitsulo komanso nthawi yayitali yogwirira ntchito. Kaya kuyerekeza ubwino wa ntchito ndivalavu ya gulugufe iwiri yosiyanakapena kusiyanitsa zochitika zogwiritsira ntchito ndivalavu ya gulugufe yapakati, ndikofunikira kusankhawopanga mavavu a gulugufendi ukadaulo wodalirika komanso mtengo wabwino.Mafakitale a ma valve a gulugufeku China akukhala maziko ofunikira pakugula padziko lonse lapansi chifukwa cha unyolo wawo waukadaulo wokhwima komanso zabwino zake. Ngati mukufuna kudziwa zambirivalavu ya gulugufe yogwira ntchito kwambirimagawo aukadaulo kapena pezani mtengo, chonde titumizireni uthenga - katswiri wopereka mayankho a ma valavu!
