Iyini i-Gate Valve
A ivalvu yesangoilawula ukugeleza koketshezi ngokuphakamisa noma ukwehlisa isango (wedge) ngokuqondile. Yakhelweimisebenzi ephelele yokuvula/yokuvala– hhayi ukulawulwa kokugeleza – inikeza ukumelana okuncane kokugeleza kanye nokuvala okuphezulu. Njengoba isetshenziswa kabanzi ku-oyili/igesi, izitshalo zamakhemikhali, kanye nokukhiqizwa kukagesi, ukuthembeka kwayo kwenza kube yinto ebalulekile ezinhlelweni zokusekela.
Isimiso Sokusebenza Se-Gate Valve
Isango lihamba liqonde ngqo ekugelezeni koketshezi. Uma liphakanyisiwe ngokugcwele, livumela ukugeleza okungenamkhawulo; uma lehliswa, lidala ukuvala okuqinile ezihlalweni zamavalvu.Ungalokothi uvule ingxenyeama-valve esango – lokhu kubangela ukuguguleka kwesivalo kanye nomonakalo wokudlidliza.
Izinyathelo Ezi-5 Ezibalulekile Zokugcina Ama-Valve Esango
Ukugcina kahle izinto kuvimbela ukugqwala futhi kuqinisekisa ukuthi ama-valve okusekelayo ayasebenza uma kudingeka.
1. Indawo Efanele Yokugcina Izinto
–Ngaphakathi Nokomile: Gcina ezindaweni ezivaliwe, ezinomswakama ophansi (<60% RH).
–Gwema Izinto Ezilimazayo: Gcina kude namakhemikhali, usawoti, noma intuthu ene-asidi.
–Ukulawula Izinga Lokushisa: Gcina izinga lokushisa liyi-5°C–40°C (41°F–104°F).(Bheka indinganiso ye-ISO 5208: Umswakama owedlulele ungaholela kalula ekugqwaleni kwezingxenye zensimbi kanye nokuguga kwezivalo zerabha.)
- Amavalvu amakhulu namancane kufanele agcinwe ngokwehlukana:Amavalvu amancane angafakwa emashalofini, futhi amavalvu amakhulu kufanele ahlelwe kahle phansi kwendlu yokugcina impahla, kuyilapho kuqinisekiswa ukuthi indawo yokuxhuma i-flange ayithinti phansi.
- Ukugcina ama-valve ngaphandle:Kumelwe uqiniseke ukuthi uzimboza ngezinto ezingangeni emvuleni nezingenalo uthuli, njenge-tarpaulin, i-linoleum, njll. (Uma izimo zivuma, kunconywa ukuthi ungazigcini ngaphandle)
Amathiphu:Gcina ivalvu yesango ngaphakathi futhi ugcine igumbi lomile futhi linomoya.
2. Ukulungiswa kweValvu
–Vala iSango: Kuvimbela ukungena kothuli.
–Amachweba OkuvalaSebenzisa izivalo ze-PVC noma amapulagi ambozwe nge-wax kuma-flange.
–Gcoba Iziqu: Faka amafutha asezingeni eliphezulu eziqwini eziveziwe.
Amathiphu:Zombili iziphetho zendlela kumele zivalwe ngephepha le-wax noma amashidi epulasitiki ukuze kuvinjelwe ukungena kokungcola.
3. Iphrothokholi Yokugcina Yesikhathi Eside
–Ukuhlolwa Kwamakota: Hlola ukugqwala, ubuqotho besivalo, kanye nokugcotshwa.
–Jikelezisa Amasondo Esandla: Jika ama-degree angu-90 njalo ezinyangeni ezi-3 ukuze uvimbele ukubhajwa.
–Imibhalo: Ama-valve ethegi anosuku lokugcina kanye nezingobo zokuhlola.
- Ukwelashwa kokungagqwali:
1. Amavalvu ensimbi (njengamavalvu esango namavalvu okumisa) adinga ukugcotshwa ngowoyela noma amafutha alwa nokugqwala, ikakhulukazi izindawo ze-flange, amalunga anezintambo kanye nezinye izingxenye ezitholakala kalula.
2. Uma igcinwe isikhathi eside (izinyanga ezingaphezu kwezingu-6), kunconywa ukuthi uhlole futhi ufake i-anti-gland agent njalo ezinyangeni ezi-3 (ngokwezinga le-API 598).
4. I-Valve Yesango Lensimbi Engagqwali Neyekhabhoni Ehlukile
- Ingozi Yokugqwala Kwe-Galvanic:
1. Ukuthintana + umswakama kudala iseli le-electrochemical.
2. Insimbi yekhabhoni iba yi-anode, igqwala ngokushesha.
3. Insimbi engagqwali (i-cathode) yonakele ungqimba lwayo oluvikelayo, okusheshisa ukugqwala kwesikhathi esizayo.
- Ukufuduka Kwekhabhoni (Ukuguqulwa Kwekhabhoni):
1. Ukuxhumana okuqondile kuvumela ama-athomu ekhabhoni ukuthi asuke ensimbini yekhabhoni aye ensimbini engagqwali.
2. Lokhu kuphazamisa isakhiwo sensimbi engagqwali, kunciphisa kakhulu ukumelana kwayo nokugqwala.
- Izindlela Ezinhle Zokugcina Isitoreji:
1. Indawo Yokugcina Ehlukile: Gcina njalo ezindaweni ezihlukile.
2. Ibanga Elincane: Gcina okungenani ukwahlukana okungu-50 cm (20 inches), ikakhulukazi ezindaweni ezinomswakama.
3. Ukuthintana Kwesikhashana: Sebenzisa izithiyo ezomile, ezingavumeli ukuhanjiswa kwamanzi (ukhuni, ipulasitiki, irabha) noma izimbozo ezivikelayo.
5. Imithetho Ebalulekile Yokwenza Kusebenze Kahle Isitoreji Samavalvu
- Ukuhlonza Ukubhala Ikhodi Yombala
• Amavalvu ensimbi engagqwali → Itheyiphu eluhlaza okwesibhakabhaka
• Amavalvu ensimbi yekhabhoni → Itheyiphu ephuzi
Kuvimbela amaphutha okuphathwa kokubona kanye nokugqwala kwe-galvanic.
- Indawo Yokuklanywa Kwempahla Ye-FIFO
• Izindawo zokugcina ezinikezelwe zivumela ukuzungezisa kokuqala kokuphuma
• Kuqeda ukuphelelwa yisikhathi kwesitoko (okubalulekile kuma-valve okusekelayo)
- Ukuhlukaniswa Kwezindleko Nokuvikelwa
• Hlukanisa amavalvu ensimbi engagqwali (kubiza izikhathi ezingu-3-5 ngaphezulu)
• Kuvimbela ukusetshenziswa kabi ngengozi kanye nomonakalo wokugqwala
- Ukuqaliswa Kobunjiniyela
• Ukucaciswa Kwendlela
• Isikhala sezindawo zokuhlukanisa ≥500mm
• Amaphedi enjoloba angahambisani nogesi angu-8-10mm okuhlukaniswa ngamakhemikhali
*Ukuthobela: Kuhlangabezana nezindinganiso ze-GB/T 20878-2017.*
Amathiphu Ochwepheshe Ababalulekile
• Amazinga ezinto eziqoshwe nge-laser (isib., “i-WCB”) ezindikimbeni zamavalvu
• Gcina i-RH engaphansi kuka-45% ezindaweni zokugcina impahla
• Amavalvu esango lokugcina aqonde phezulu – ukubekwa okuvundlile kuphazamisa ukuvalwa okuphuthumayo
Ukuqhathaniswa Kwezindlela Zokugcina I-Backup Gate Valve
Ukulungiswa Kwevalvu Yesango: Izinqubo Ezi-4 Eziyinhloko
1. Ukunakekelwa Kokusebenza Okuvamile
–Gcoba Imicu: Faka i-molybdenum disulfide paste kuma-stem nuts njalo ngekota.
–Ingaphandle Elihlanzekile: Sula ukungcola/imfucumfucu njalo ngenyanga ngezindwangu ezingagugi.
–Hlola Amasondo Esandla: Qinisa amabhawodi akhululekile ngokushesha ukuze ugweme ukungalungi kahle.
2. Ukupakisha/Ukunakekelwa Kwezindlala
–Hlola njalo ngekota: Bheka ukuvuza okuzungeze isiqu.
–Lungisa Amantongomane E-Gland: Qinisa kancane kancane uma kuvela ukukhala –ungacindezeli ngokweqile.
–Buyisela UkupakishaSebenzisa intambo efakwe i-graphite njalo eminyakeni emi-2-5.
3. Izindlela Ezinhle Zokugcoba
| Inkinga | Isixazululo |
| Ukugcotshwa okunganele | Faka amafutha kuze kube yilapho ephuma ezivalweni |
| Ukugcoba ngokweqile | Yeka uma ukumelana kukhula (ubuningi be-3,000 PSI) |
| Igrisi Eqinisiwe | Hlanza nge-parafini ngaphambi kokugcoba kabusha |
4. Ukunakekelwa Kwesistimu Yokudlulisela
–Ama-gearbox: Shintsha uwoyela minyaka yonke (kunconywa i-ISO VG 220).
–Ama-Actuator kagesi: Hlola izivalo zomswakama kabili ngonyaka.
–Ukweqa Okwenziwa Ngokuzithandela: Bhalisa njalo ngenyanga ukuze uvimbele ukuquleka.
Amathiphu Akhethekile Ama-Backup Valve
–Ukukhululeka Ekucindezelekeni: Vula amapulagi okukhipha amanzi ngaphambi kokugcoba ukuze uvimbele ukuqhuma kwesivalo.
–Ukubeka Indawo: Amavalvu esango lesitoloivaliwe ngokupheleleukugcina izimpawu zomlilo zibambekile.
–Amakhithi Ezimo Eziphuthumayo: Gcina izinto zokupakisha ezisele kanye namantongomane eduze.
Isiphetho: Ukukhulisa Isikhathi Sokuphila Sevalvu
Landela le mithetho yama-valve esango asekelayo athembekile:
1. Isitoreji= Yomile, ivaliwe, futhi ibhaliwe.
2. Ukulungiswa= Ukugcoba okuhleliwe kanye nokuhlolwa.
3. Ukulungiswa= Lungisa ukuvuza ngokushesha.
Ngokubeka phambili ukunakekelwa okusebenzayo, ugwema ukwehluleka kwama-valve okungu-80% - okubaluleke kakhulu ezinhlelweni eziphuthumayo.
