9. Kurongedza & Kutumira – Cryogenic Globe Valve (-196°C)
Kurongedza
- Dziviriro:Mavharuvhu ese akaputirwa nepepa rinodzivirira ngura kana bepa reVCI. Maflanges nekubatanidza kwekupedzisira kwakafukidzwa nemapurasitiki kana mablange esimbi anovhara.
- Kudzivirira Kuguma:Zvivharo zvepurasitiki zvemagumo eSW/NPT; maflange esimbi ane magasket emagumo akaputirwa. Zvivharo zvemabutt zvakadzivirirwa nemapurasitiki kana simbi.
- Mabhokisi emapuranga:Kune mavharuvhu madiki, mayuniti ega ega kana akawanda akaiswa mumabhokisi emapuranga akasimba ane furo. Mabhokisi eplywood emhando yepamusoro anotumirwa kunze kwenyika ane mabraces emakona.
- Matanda eSimbi:Pamavharuvhu makuru, mapuranga esimbi ega ega ane zvitsigiro zvakapinza. Mavharuvhu akasimbiswa nemabhaudhi pachigaro.
- Chinobvisa tsvina:Mabhegi eSilica gel desiccant akaiswa mumabhokisi kuti anwe hunyoro.
Kutumira
- Nzira yekufambisa:Kutakura zvinhu nendege kwemavharuvhu ekukurumidzira; kutakurwa kwezvinhu negungwa kwemavharuvhu makuru uye kuodha zvinhu zvakawanda.
- Kuisa mumidziyo:Mavharuvhu madiki anoiswa mupallet uye anoiswa mumidziyo; mavharuvhu makuru ari mumidziyo yakatsetseka.
- Kunyora mazita:Kereti yega yega yakanyorwa nenhamba ye vharuvhu, saizi, kirasi yekumanikidza, zvinhu, nhamba ye serial, uye mirairo yekubata.

10. Mabhenefiti eSimbi yeWomic & Mibvunzo Inowanzo bvunzwa - Cryogenic Globe Valve (-196°C)
Sei Uchifanira Kushanda NeWomic Steel Kuti Uwane Cryogenic Globe Valves?
Saizi Yakazara: 1/2" – 24" (DN15 – DN600), Kirasi 150 – Kirasi 900.
Kurapa kweDeep Cryogenic pa -196°C - kunovimbisa kugadzikana kwezvikamu (sekureva kweBS 6364).
Kushanda kwe cryogenic kwakavimbiswa - mavharuvhu 100% akaedzwa pa -196°C pa BS 6364.
Kuvakwa kwebhoneti ine bhoti - kuvharwa kwakavimbika uye kuri nyore kugadzirisa.
Bhoneti yakatambanudzwa ine drip plate - yakajairika kune mavharuvhu ese e cryogenic globe.
Kuburitsa hutsi hushoma - ISO 15848-1 Kirasi A kana B yekurongedza.
Sarudzo yezvinhu zvemuviri: LCB, LCC, CF3, CF3M, CF8, CF8M.
Sarudzo yezvigaro: PCTFE (chigaro chikuru che cryogenic), RPTFE, PEEK, Stellite.
Kumaka kwePED 2014/68/EU CE.
Nguva dzekutungamira dzinokwikwidzana: mavhiki 8-12 ekugadzirisa kwakajairika.
Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa) - Cryogenic Globe Valve (-196°C)
Mubvunzo: Ndeupi musiyano uripo pakati pevharuvhu yeglobe inonzi cryogenic nevharuvhu yeglobe yakajairwa?
A: Mavharuvhu eCryogenic globe ane zvinhu zvakakosha zvisingawanikwe mumavharuvhu akajairwa: bhoneti yakatambanudzwa ine drip plate yekudzivirira stem seals; kurapwa kwakadzika kwezvikamu zvese zvecryogenic; zvinhu zvechigaro zvakanongedzerwa (PCTFE, PEEK) zvekupisa kwakaderera; kurongedza kwakaderera kwekubuda kwemhepo; uye kuyedzwa kwekushanda kwecryogenic kunofanirwa kuteverwa zvichienderana neBS 6364.
Mubvunzo: Ndeipi tembiricha shoma yekushanda kwemavharuvhu enyu e cryogenic globe?
A: Mavharuvhu edu e cryogenic globe akajairwa akapihwa sevhisi ye -196°C pa BS 6364. Kune sevhisi ye liquid hydrogen (-253°C) kana liquid helium (-269°C), tinopa magadzirirwo akasarudzika.
Mubvunzo: Chii chinonzi kurapwa kwe deep cryogenic uye nei kuchidikanwa?
A: Kurapa kwakadzika kwe cryogenic inzira yekutonhodza zvikamu zvevharuvhu kusvika -196°C kwemaawa masere. Izvi zvinoshandura austenite yakachengetwa, zvinoderedza kushushikana kwakasara, uye zvinovimbisa kugadzikana kwehukuru pakupisa kwekushanda.
Mubvunzo: Ndezvipi zvinhu zvechigaro zvamunokurudzira pabasa re -196°C?
A: Pabasa re -196°C, tinokurudzira PCTFE sechigaro chikuru. PCTFE inochengetedza hunhu hwayo hwemakanika uye inopa chisimbiso chakanaka pakupisa kwe cryogenic.
Mubvunzo: Kuongororwa kwekushanda kwe cryogenic kunosungirwa here?
A: Maererano neBS 6364 neISO 28921-1, kuyedzwa kwekushanda kwe cryogenic kunosungirwa kumavharuvhu anoshandiswa muLNG uye sevhisi ye cryogenic. Womic inoita 100% kuyedzwa kwekushanda kwe cryogenic.
Q: Munopa chisimbiso chebellows here kana pasina kuburitsa mvura?
A: Ehe. Pakushandisa kwakakosha kusingadi kuti dzinde risabude (senge mvura ine njodzi kana inodhura), tinopa dhizaini yechisimbiso chebellows chine chigaro chekumashure chechipiri.
Q: Ndeipi nguva yakajairika yekutungamira kwemavharuvhu epasi pe cryogenic?
A: Nguva yakatarwa yekuendesa zvinhu imavhiki 8-12 ekugadzirisa zvinhu zvakajairwa. Kune saizi hombe (> 12") kana zvinhu zvakakosha, nguva yakatarwa imavhiki 12-16.

Mashandisirwo:Kudzora nekudzora kuburitswa kwechigadzirwa chenitrogen yemvura (-196°C) uye oxygen yemvura (-183°C). Dhizaini yekumanikidza: 5.0 MPa. Bhoneti yakawedzerwa ine drip plate, inoshandiswa nevhiri reruoko.
Matambudziko ehunyanzvi nemhinduro:
1. Kudzora kuyerera kwakarurama pa -196°C kuti chigadzirwa chive chakachenaZvinodiwa pakuchena kwechigadzirwa cheASU (99.999% yegiredhi remagetsi) zvinoda kudzorwa kwakaringana kwekuyerera kwemvura. Mavharuvhu eWomic ane zvigaro zvePCTFE uye madhisiki eStellite akaomarara kuti akwanise kudzikamisa tambo. Mavharuvhu ese 120 akapfuura bvunzo ye cryogenic pasina kubuda kwemvura.
2. Kurapa kwakadzama kwe CF3M bodiesMiviri yeCF3M yakaumbwa inogona kubatwa neaustenite yakachengetedzwa. Womic yakarapa cryogenic cycles nhatu (-196°C, maawa gumi nemaviri pacycle). Kuongororazve kwakaratidza kuti hapana kukanganiswa.
3. Kurongedza kushoma kwekubuda kwemhepo kunopa basa reokisijeniKushanda kweokisijeni kunoda kuchena kwakasimba uye kurongedza mweya usina kusvibiswa zvakanyanya. Womic inopihwa ISO 15848-1 Class A packing ine mafuta anoenderana neokisijeni.
4. Kuongororwa kwevamwe neBVMutengi aifanira kuona ongororo kubva kuBureau Veritas. BV yakapa zvitupa mukati memazuva gumi.
Mhedzisiro:Kuwedzerwa kweASU kwakatanga kushanda zvakanaka. Mavharuvhu ese e120 cryogenic globe ave achishanda pa -196°C kwemwedzi inopfuura 18 pasina zviitiko zvekugadzirisa.
