Segment Ball Valve, Segment Wafer Ball Valve, V mtundu wa Ball Valve

Mawu Oyamba

Vavu yamtunduwu ndi ya valavu yokhazikika ya mpira komanso ndi valavu imodzi yosindikizira mpira.Kusintha kwabwino kwambiri mu valavu ya mpira, mawonekedwe othamanga ndi ofanana peresenti, ndipo chiŵerengero chosinthika ndi 100: 1.Kung'ambika kwake kooneka ngati V kumameta ubweya ndi mpando wachitsulo, makamaka koyenera kwa media okhala ndi ulusi, tinthu ting'onoting'ono tolimba, slurry.

Vavu ya mpira imakhala ndi kuzungulira kwa digirii 90, kupatula kuti thupi la pulagi ndi lozungulira lomwe lili ndi zozungulira kudutsa dzenje kapena njira yodutsa mumzere wake.Vavu ya mpira imagwiritsidwa ntchito makamaka mu payipi kudula, kugawa ndikusintha njira yoyendetsera sing'anga.Imangofunika kuzunguliridwa madigiri 90 ndipo torque imatha kutsekedwa mwamphamvu.Mavavu a mpira ndi oyenera kugwiritsidwa ntchito ngati ma valve osinthira ndi otseka, koma zomwe zachitika posachedwa zapanga ma valve a mpira kuti azitha kuyendetsa bwino komanso kuyendetsa bwino, monga ma valve a V-ball.

Makhalidwe

Oyenera kugwira ntchito pafupipafupi, kutsegula ndi kutseka mwachangu, kulemera kwapang'onopang'ono, kukana kwamadzimadzi pang'ono, kapangidwe kosavuta, voliyumu yaying'ono, kulemera kwapang'onopang'ono, kukonza kosavuta, kusindikiza kwabwino, kosalephereka ndi njira yoyika, njira yoyendetsera sing'anga imatha kukhala yosasunthika. , palibe kugwedezeka, phokoso lochepa .

1. Mapangidwe a monolithic a thupi la valve: Thupi la valve la mtundu wa clamp ndi valavu ya mtundu wa V-mtundu wa flange ndi mbali zonse zomwe zimakhala ndi mbali, zomwe zimakhala zolimba kwambiri ndipo zimakhala zosavuta kuyambitsa ndi kutayikira.

2. Mapiritsi apamwamba ndi otsika odzipangira okha: Thupi la valve liri ndi zitsulo zapamwamba komanso zochepetsera zodzipangira zokha, zomwe zimakhala ndi malo akuluakulu okhudzana ndi tsinde la valve, mphamvu yonyamula katundu ndi coefficient yaing'ono, yomwe imachepetsa mphamvu ya valve.

3, mpando valavu akhoza kusankhidwa malinga ndi zosowa za sing'anga ndi zikhalidwe ntchito, zitsulo zolimba chisindikizo kapena PTFE zofewa chisindikizo: chitsulo cholimba chisindikizo mpando kusindikiza pamwamba pamwamba aloyi olimba, ozungulira zolimba chrome kapena kuwotcherera utsi, nitriding ion ndi kuumitsa mankhwala. , Moyo wautumiki wa malo osindikizira umakulitsidwa ndipo kukana kwa kutentha kumakhala bwino;chofewa chosindikizira PTFE mpando valavu kapena analimbitsa PTFE valavu mpando ali ndi ntchito yabwino kusindikiza ndi kukana dzimbiri, ndipo ali lonse kusinthasintha.

4. Economic and practicability: Thupi la valve ndi lolemera kwambiri, tsinde la valve torque ndi laling'ono, ndipo zizindikiro zofanana za pneumatic kapena magetsi oyendetsa magetsi ndizochepa, zomwe zimakhala zotsika mtengo poyerekeza ndi mitundu ina ya ma valve oyendetsa.

5, sing'anga amazolowera zosiyanasiyana: chifukwa cha kukameta ubweya mphamvu pakati pa V woboola pakati kutsegula V ndi valavu mpando, ndi yosalala ndi wozungulira otaya njira ya patsekeke valavu, sing'anga si zophweka kudziunjikira mkati mkati, kotero ndi oyenera madzi sing'anga, Oyenera dongosolo kulamulira ndi CHIKWANGWANI ndi olimba tinthu media.

Mapangidwe ndi kupanga miyezo

1. Flange muyezo: ASME B 16.5, EN 1092-1: 2001, GB/T 9113.1-2010, JB/T 79.1-1994, HG/T20592-2009

2. Kutentha-kutentha: ASME 816.34-2003, IS0 7005-1

3. Muyezo wa kutalika kwa kamangidwe: Mtundu wa clip: mtundu wamalonda wa Flange: ISAS75.04-1995, IEC/DIN534-3-2

4, atengere kutentha osiyanasiyana: -29 °C -1 ~ 500C yachibadwa kutentha mtundu 2goC_2500C sing'anga kutentha mtundu 2goC_3500C mkulu kutentha mtundu

5, kusindikiza ndi kuyesa mphamvu miyezo

Mphamvu ndi kusindikiza mayeso muyezo: GB/T 4213-2007

Mulingo wosindikizira Wolimba: Ngati wogwiritsa ntchito alibe zofunikira zapadera, muyezo wotsatira wa tebulo umagwiritsidwa ntchito.Wogwiritsa ntchito akapempha, akhoza kuchitidwa molingana ndi mulingo wa GB/T 4213-2007?V.Kuthamanga kwa mayeso a mphamvu ndi 1.5 nthawi za kukakamiza mwadzina.Kuyesa kwa chisindikizo pa kulongedza ndi ku flange kumachitika pa kukakamiza kwa 1.1 nthawi zambiri.Chisindikizo cha mpando chimayesedwa molingana ndi kusiyana kwakukulu kwa kuthamanga.Pamene kusiyana kwakukulu kwa kuthamanga sikumveka bwino, yesetsani kuyesa kwa 1.0MPa (kuthamanga kwa madzi), pamene kusiyana kwakukulu kwa kuthamanga kuli kochepa kuposa 0.6MPa, kuyesako kumachitidwa ndi mphamvu ya 0.6MPa, ndipo sing'anga imayesedwa ndi madzi ndi dzimbiri. ndi scale inhibitor.
