Ama-valve okusakaza ama-valve enziwe ngokuphonsa.Ngokuvamile, izilinganiso zokucindezelwa kwamavalvu okuphonswa ziphansi kakhulu (ezifana ne-PN16, PN25, PN40, kodwa zikhona futhi ezinengcindezi ephezulu, ezingafinyelela ku-1500Lb, 2500Lb), futhi eziningi zazo zingaphezu kwe-DN50.Amavalvu omgunyathi akhiwe futhi asetshenziswa ngokujwayelekile kumapayipi ebanga eliphezulu anamacaliber amancane uma kuqhathaniswa, ngokuvamile angaphansi kwe-DN50.
1. Ukulingisa
1. Ukubunjwa: Kuyinqubo yokuncibilikisa insimbi ibe uketshezi oluhlangabezana nezimfuneko ezithile bese luluthela esikhunjeni.Ngemuva kokupholisa, ukuqiniswa, nokuhlanza, ukusakaza (ingxenye noma okungenalutho) okunomumo onqunywe kusengaphambili, usayizi nokusebenza kuyatholakala.Ubuchwepheshe obuyisisekelo bemboni yesimanje yokukhiqiza imishini.
2. Uvolo owenziwe ngensimbi nawo unezindleko eziphansi, futhi ungabonisa ukusebenza kahle kwawo ukonga izingxenye ezinezimo eziyinkimbinkimbi, ikakhulukazi ezinezimbotshana zangaphakathi eziyinkimbinkimbi;ngesikhathi esifanayo, inokuguquguquka okubanzi kanye nezakhiwo ezingcono zemishini.
3. Izinto (ezifana nensimbi, ukhuni, uphethiloli, izinto zokumodela, njll.) nezinto zokusebenza (ezifana neziko lensimbi, izixube zesihlabathi, imishini yokubumba, imishini ewumgogodla yokwenza, imishini yokuthungula, imishini yokudubula, amapuleti okusansimbi, njll.) edingekayo ekukhiqizeni ukusakaza ) Ingaphezulu, futhi izokhiqiza uthuli, igesi eyingozi nomsindo futhi ingcolise imvelo.
4. Ukusakaza kuwuhlobo lobuchwepheshe bokucubungula okushisayo kwensimbi isintu esiye sakwazi ngaphambili, nomlando weminyaka engaba ngu-6000.
Ngo-3200 BC, kwavela ukukhishwa kwamasele ethusi eMesopotamiya.Phakathi kwekhulu le-13 BC kanye nekhulu le-10 BC, iShayina ingene endundumeni yokubukisa ngethusi.
Ubuciko bufinyelele ezingeni eliphezulu kakhulu, njenge-Simuwu Fangding Ding engu-875 kg evela ebukhosini bakwa-Shang, ipuleti le-Zenghou Yizun kusukela ku-Warring States Period, kanye nesibuko esikhanyayo esivela ku-Western Han Dynasty zonke zimelela ukulingisa kwasendulo.
umkhiqizo.Ukubunjwa kwasekuqaleni kwakuthonywe kakhulu izitsha zobumba, futhi okuningi kokubunjwa kwakungamathuluzi noma izitsha zokukhiqiza ezolimo, inkolo, nokuphila.
Umbala wobuciko unamandla.Ngonyaka wama-513 ngaphambi kokuzalwa kukaKristu, iShayina yaphonsa insimbi yokuqala emhlabeni (isisindo esingamakhilogremu angama-270), engatholakala kumarekhodi abhaliwe.
Cishe ngekhulu lesi-8, iYurophu yaqala ukukhiqiza insimbi.Ngemuva kweNguquko Yezimboni ngekhulu le-18, ukulingisa kwangena esikhathini esisha sokusebenza ezimbonini ezinkulu.
Ekhulwini lama-20, ukuthuthukiswa okusheshayo kokulingisa kuye kwathuthukiswa.I-Nodular cast iron, insimbi egayiwe ethambile, insimbi engagqwali ye-ultra-low, i-aluminium yethusi, i-aluminium silicon, nama-alloys e-aluminium-magnesium athuthukiswe ngokulandelana.
Ukusakaza izinto zensimbi ezifana ne-titanium-based and nickel-based alloys, futhi kusungulwe inqubo entsha yokujova insimbi empunga.Ngemuva kweminyaka yawo-1950s, kwavela ukumodela okunengcindezi ephezulu kwesihlabathi esimanzi,
Ukumodela kwesihlabathi sokuqina kwamakhemikhali nokwenza ingqikithi, ukumodela kwengcindezi engalungile, okunye ukulingisa okukhethekile, ukuqhunyiswa kwesibhamu nobunye ubuchwepheshe obusha.
5. Kunezinhlobo eziningi zokulingisa, ezihlukaniswe zibe: ①Ukubunjwa kwesihlabathi okuvamile, okuhlanganisa izinhlobo ezi-3 zesihlabathi esiluhlaza, isihlabathi esomile nesihlabathi esiqiniswe ngamakhemikhali.②Ukubunjwa okukhethekile, ngokwezinto zokumodela, kungahlukaniswa ngokusakazwa okukhethekile ngesihlabathi samaminerali emvelo kanye netshe njengezinto eziyinhloko zokumodela (njengokubunjwa kokutshalwa kwezimali, ukubunjwa kobumba, ukuphonsa igobolondo leshabhu yokusebenzela, ukuphonsa ingcindezi engemihle, ukuphonsa okuqinile, ukubunjwa kwe-ceramic) Njll.) kanye nokusakazwa okukhethekile ngensimbi njengento eyinhloko yokubumba (njengokubunjwa kwensimbi yensimbi, ukucindezela ukucindezela, ukusakaza okuqhubekayo, ukukhishwa kwengcindezi ephansi, ukukhishwa kwe-centrifugal, njll.).
6. Inqubo yokubunjwa ngokuvamile ihlanganisa: ①Ukulungiswa kwezibunjwa (iziqukathi ezenza insimbi ewuketshezi ibe ukubunjwa okuqinile).Izibunjwa zingahlukaniswa zibe isihlabathi, insimbi, i-ceramic, ubumba, i-graphite, njll, ngokusho kwenani lezikhathi zokusetshenziswa.Ngokulahlwayo, okuhlala isikhathi eside futhi unomphela, ikhwalithi yokulungiswa kwesikhunta yisici esiyinhloko esithinta ikhwalithi yokukhipha;②Ukuncibilika nokuthululwa kwezinsimbi ezisansimbi, izinsimbi ezisansimbi (ama-alloys) ikakhulukazi zihlanganisa insimbi ekhonjiwe, insimbi ekhonjiwe kanye nama-alloys angeyona ayoni;③ Ukucubungula nokuhlolwa kokusakaza.Ukucutshungulwa kwe-casting kuhlanganisa ukususwa kwemizimba yangaphandle enkabeni nangaphezulu kokubunjwa, ukususwa kwezikhuphukeli ezithelayo, ukufoshwa kwama-burrs nama-drape seams, kanye nokwelashwa kokushisa, ukubunjwa, ukwelapha ukugqwala kanye nomshini onzima.Ngenisa i-valve yephampu

I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.

Imikhiqizo emikhulu:I-Butterfly Valve,I-Ball Valve,Ivalve yesango,Hlola Valve,I-Globe Vavlve,I-Y-Strainers,I-Acurator kagesi,Ama-Acurator Womoya.
