Isebenza Kanjani Ivalvu Yebhola: Umhlahlandlela Ophelele - Ivalvu Ye-NSW

Isingeniso: Ingxenye Ebalulekile Ezinhlelweni Zoketshezi

I-valve yebhola isebenza ngokujikeleza ibhola eliyindilinga elinembobo ebholiwe ukulawula ukugeleza koketshezi.Uma imbobo ihambisana nepayipi, ivalvu ivulekile; uma ijikeleziswa ngama-degree angu-90, ingxenye eqinile yebhola ivimba ukugeleza, ihlinzeke ngokuvala okuqinile ngokunciphisa ukucindezela.

Ukuqonda ukuthi i-ball valve isebenza kanjani kubalulekile konjiniyela, amaqembu okulungisa, kanye nochwepheshe bokuthenga ababandakanyeka ezinhlelweni zamanzi ezimboni.amavalvu ebholazivame ukubonwa njengamadivayisi alula okuvula/ukuvala, ukwakheka kwawo kwangaphakathi, izinto zokwakha, kanye nokucushwa kwawo kuthinta ngqo ukuphepha kokusebenza, ukusebenza kahle, kanye nezindleko eziphelele zobunikazi.

Lo mhlahlandlela udlula ngale kwencazelo eyisisekelo. Uhlanganisaukuqonda kobuchwepheshe ezingeni lobunjiniyelangeukucatshangelwa kokuthola okusebenzayo kanye nomjikelezo wokuphila, kusiza onjiniyela kanye nabathengi ukuthi benze izinqumo ezinolwazi.

Isebenza Kanjani Ivalvu Yebhola? (Kuchazwa Isimiso Sokusebenza)

I-valve yebhola isebenza ku-isimiso sokusebenza sekota:

1. Isikhundla Esivulekile
   Uma isibambo noma i-actuator ihambisana nepayipi, imbobo yangaphakathi yebhola ihambisana nendlela yokugeleza. Uketshezi ludlula ngaphandle kokuphazanyiswa okuncane kanye nokulahlekelwa yingcindezi.

2. Isikhundla Esivaliwe
   Ukujikeleza isibambo noma i-actuator ngama-degree angu-90 kuphendula ibhola ukuze uhlangothi lwayo oluqinile luvimbele ukugeleza. Isihlalo esingezansi sicindezelwa ngokuqinile ebholeni yingcindezi yesistimu, okudalauphawu olusizwa ukucindezela.

Ukuqonda Kobunjiniyela:
I-torque yokusebenza ye-ivalvu yebholaayihlali njalo. I-torque ephezulu kakhulu yenzeka ngesikhathi sokuqhekeka kokuqala (“i-torque yokuphumula ukuze isebenze”). Amanani e-torque anembile anikezwa umenzi abalulekile ekulinganisweni kwe-actuator okulungile kanye nokuthembeka kwesikhathi eside.

Umhlahlandlela Wokuklama Nokukhetha Amavalvu Ebhola Wezicelo Zezimboni

Ukuthembeka kwevalvu yebhola kuvela ekwakhiweni kwayo okuqinile kwemishini, kodwa ukusebenza kuyahlukahluka kakhulu kuye ngemininingwane yokwakha kanye nokukhethwa kwezinto.

Izingxenye Eziyinhloko Nokucatshangelwa Kwezinto Ezibalulekile

Umzimba weValve

Umzimba usebenza njengengxenye eyinhloko yokugcina ingcindezi. Izinto ezivamile zifaka phakathi insimbi yekhabhoni (i-WCB), insimbi engagqwali (316), kanye nensimbi engagqwali ephindwe kabili. Ukukhetha kuncike esigabeni sengcindezi, izinga lokushisa, ukumelana nokugqwala, kanye nezindleko.

Inothi Lokuthola Imithombo:
Qinisekisa njalo izitifiketi zokuhlolwa kwezinto (ama-MTC) ngokuhambisana nezindinganiso ze-ASME noma ze-ASTM.

Ibhola

Ibhola liqukethe imbobo yokugeleza futhi liyajikeleza ukulawula ukugeleza. Ukuqeda okungaphezulu kanye nokwemboza okufana ne-chrome plating eqinile noma i-ceramic coating kuthuthukisa ukumelana nokuguguleka futhi kunciphisa ukugabha.

Ngezinhlelo zokusebenza zokulawula,Amabhola e-V-portinikeza ukunemba okuthuthukisiwe kokugoqa uma kuqhathaniswa nemiklamo ejwayelekile ye-round-port.

Izihlalo

Izihlalo zakha uphawu phakathi kwebhola nomzimba we-valve. Izinto ezivamile zezihlalo zifaka:

• I-PTFE / RPTFE:Ukungqubuzana okuphansi, okulungele izinsizakalo eziningi

• Ama-polymer athuthukisiwe kanye ne-PEEK:Kwamazinga okushisa aphezulu kanye nokucindezela

• Izihlalo zensimbi:Kuyadingeka ngezinsizakalo ezirhabaxa noma ezishisa kakhulu

Amavalvu ebhola aphephile emlilweni kumele ahambisaneI-API 607 ​​noma i-ISO 10497amazinga.

Isiqu

Isiqu sidlulisela i-torque kusuka ku-actuator kuya ebholeni.isiqu esingaphumikuyisici esibalulekile sokuphepha. Ukupakisha i-graphite enezindandatho eziningi eneziphethu ezithwala izinto eziphilayo kuqinisekisa ukuvalwa kwesikhathi eside kanye nokunciphisa ukukhishwa kwegesi okusabalele.

Izinhlobo zama-Ball Valve: I-Full Port, i-Reduced Port, kanye ne-Trunnion Mounted

Ukukhetha uhlobo lwe-ball valve olufanele kungenye yezinqumo ezibaluleke kakhulu kwezobuchwepheshe nakwezentengiselwano.

Inothi Lobunjiniyela:
Amavalvu ebhola afakwe ku-trunnionukusekela ibhola kuzo zombili izinhlangothi, kunciphisa umthwalo wesihlalo kanye ne-torque yokusebenza, okwenza kube kuhle kakhulu kwizicelo ze-Class 600+ kanye nobubanzi obukhulu.

Izicelo ze-Common Ball Valve

Ngenxa yokuvalwa kwawo okuqinile, ukusebenza okusheshayo, kanye nezidingo zokunakekelwa eziphansi, ama-ball valve asetshenziswa kabanzi emikhakheni yezimboni:

• Amapayipi kawoyela negesi

• Ukucubungula ngamakhemikhali kanye ne-petrochemical

• Ukwelashwa kwamanzi kanye nokukhishwa usawoti emanzini

• Izinhlelo zokuphehla ugesi

• Ukudla, iziphuzo, kanye nokucubungula imithi (ama-valve ebhola lenhlanzeko)

Umklamo we-ball valve ofanele kakhulu uncike ku-uhlobo lwemidiya, ingcindezi, izinga lokushisa, imvamisa yomjikelezo, kanye nezidingo zokuphepha.

Amavalvu Ebhola Asetshenziswa Ngesandla Nangokuzenzakalelayo

Amavalvu Ebhola Enziwe Ngesandla

Amavalvu ebhola asetshenziswa ngesandla asebenzisa izibambo ze-lever noma ama-gearbox. Alula, ashibhile, futhi afanele ukusetshenziswa njalo.

Amavalvu Ebhola Azenzakalelayo

Amavalvu ebhola azenzakalelayo asebenzisa ama-actuator kagesi, omoya, noma e-hydraulic ukuze asebenze kude noma njalo.

Icebiso Lokuthenga:
Qinisekisa ukuthi i-valve kanye ne-actuator mounting interface ziyahambisana, ngokuvamileI-ISO 5211amazinga.

Amavalvu Ebhola Akhethekile Emisebenzi Ethile

• Ama-V-Port Ball Valve:Yakhelwe ukulawula ukugeleza kanye nokugoba

• Amavalvu Amabhola Anezimbobo Eziningi (ayizindlela ezi-3 / ayizindlela ezi-4):Isetshenziselwa ukuphambukisa, ukuxuba, noma ukushintsha ukugeleza

• Amavalvu Ebhola Elikhipha Umoya Ophansi (LE):Yenzelwe ukunciphisa ukukhishwa kwegesi okusabalele futhi ihambisane ne-ISO 15848

Ngezicelo ezikhipha ukungcola okuphansi, imibiko yokuhlola eqinisekisiwe kufanele ihlale idingeka ngesikhathi sokuthola.

Ukufakwa, Ukugcinwa, kanye Nezindleko Zomjikelezo Wokuphila

Izindlela Ezinhle Zokufaka

1. Hlukanisa futhi unciphise ukucindezeleka kwepayipi ngaphambi kokufakwa

2. Qinisekisa ukuhambisana kahle kwe-flange ngaphandle kokuphoqa

3. Ngesikhathi sokushisela, vikela izihlalo zangaphakathi ekushiseni okweqile

4. Sebenzisa izivalo zokuzivikela ngesikhathi sokuthutha nokugcina

Ukulungiswa Nokuxazulula Izinkinga

• Zungezisa ama-valve ngezikhathi ezithile ukuze uvimbele ukunamathela

• Hlola ukupakisha isiqu kanye nezimpawu zomzimba ukuze kutholakale ukuvuza kwangaphandle

• Ukuvuza kwangaphakathi kuvame ukukhombisa umonakalo wesihlalo noma ibhola

• Gcina izingxenye ezibalulekile zama-valve abaluleke kakhulu

Ukuhlaziywa Kwezindleko Zomjikelezo Wempilo: Ngale Kwentengo Yokuqala

Ngokombono wokuthengwa, ukukhethwa kwamavalvu ebhola kufanele kusekelwe kuIzindleko Eziphelele Zobunikazi (i-TCO)kunokuba kube yintengo yeyunithi kuphela:

1. Izindleko Zokuthola:I-valve, i-actuator, izesekeli

2. Izindleko Zokufaka:Kuthonywa usayizi, isisindo, kanye nobunzima

3. Izindleko Zokusebenza:Ukulahlekelwa yingcindezi, ukusetshenziswa kwamandla, ukulungiswa

4. Izindleko Zengozi:Isikhathi sokungasebenzi, izehlakalo zokuphepha, kanye nemiphumela yokwehluleka

Isiphetho: Ukuvumelanisa Izidingo Zobunjiniyela Nokuthola Amasu

Amavalvu ebholakungase kubonakale kulula, kodwa ukusebenza kwabo kuwumphumela wobunjiniyela obucophelelayo kanye nokukhetha okunolwazi. Onjiniyela kumele bachaze ngokucacile izimo zokusebenza, kuyilapho abathengi kumele bahlole inani lesikhathi eside besebenzisa ukuhlaziywa kwezindleko zomjikelezo wokuphila.

Njengoba izinhlelo zezimboni zithuthuka,amavalvu ebhola ahlakaniphile futhi anikwe amandla yinzwakuba yinto ebaluleke kakhulu ekugcinweni kwezibikezelo kanye nokuhlanganiswa kwedijithali.

Ngokuhlanganisa ukuqonda okuqinile kokuthi i-ball valve isebenza kanjani nemikhuba yokuthola amasu, izinhlangano zingafinyelela imisebenzi ephephile, ukuthembeka okuthuthukisiwe, kanye nembuyiselo ephezulu ekutshalweni kwezimali.
