I-Parallel Slide Gate Valve: Umhlahlandlela Ophelele Wezici, Izinhlobo Nezinhlelo Zokusebenza

Iyini i-Parallel Slide Gate Valve

I-Parallel Slide Gate Valve iyi-valve eshelelayo elawula ukuvulwa/ukuvalwa ngama-disc e-parallel gate. Ilungu layo lokuvala (i-gate disc) linezindawo zokuvala ezicwebezelisiwe kakhulu, ezisicaba ezihambisana kahle nesihlalo, ikakhulukazi ezisetshenziselwa ukuvala noma ukuxhumanisa ukugeleza kwemidiya.

Isimiso Sokusebenza

Ivalvu yesango elihambisanayo isebenzisa isakhiwo sediski esihambisanayo esikabili. Indlela yokushayela ihambisa isango ngokuqondile ukuze ivule/ivale indlela yoketshezi. Isango linembobo elingana nobubanzi bangaphakathi bepayipi. Ukujikeleza isondo lesandla noma ukusebenzisa i-actuator kuphakamisa/kwehlisa isiqu kanye nesango. Lapho imbobo yesango ihambisana nepayipi, uketshezi luyageleza (ivalvu iyavuleka). Lapho isango livimba indlela yokugeleza (imbobo ibuyele ekamelweni levalvu), ivalvu iyavala.

Izingxenye Eziyinhloko Zamavalvu Esango Elihambisanayo

I-Valve Body & Gate Disc

Umzimba ubunjiwe noma wenziwe ngensimbi yekhabhoni, insimbi engagqwali, njll., ugcina amadiski esango ahambisanayo. Umklamo wamadiski amabili uthuthukisa ukuvalwa. Ukunyakaza kwamadiski aqondile kulawula ukugeleza.

Ukuhlanganiswa Kwesiqu Nokuvala

Isiqu (i-alloy/insimbi engagqwali) sixhuma esangweni ngemicu. Izingxenye zokuvala zifaka izihlalo ze-alloy eziqinile, i-PTFE, noma izindandatho ze-graphite eziqinisekisa ukuvalwa okuqondiswayo.

Indlela Yokushayela

Ama-actuator ahambisana nezindinganiso ze-API 6D, asekela ukusebenza ngesandla, ngogesi, noma ngomoya. Izinketho ezingamelani nokuqhuma ziyatholakala.

Isakhiwo Sokuvala

Inezihlalo ezintantayo ezinokufakwa kusengaphambili ukuze kufakwe uphawu oluqondiswe kabili. Izinto zokwakha: i-graphite eqinisiwe, i-PTFE.

Ezinye Izingxenye Ezibalulekile

Isikhwama Se-Yoke: Ithusi le-aluminium linciphisa i-torque yokusebenza.

Indandatho Yesihlalo: Ishiselwe ukuze kube lula ukuyilungisa.

Amavalvu Esango Leslayidi Elihambisanayo Elinomoya Uma Liqhathaniswa Nelingenamoya

Umehluko omkhulu usekwakhekeni, emsebenzini, kanye nokusetshenziswa. Amavalvu angenawo umoya anembobo yokunciphisa ingcindezi, ukufaka ama-pig, kanye nokuvikela izihlalo emapayipini amade. Amavalvu angenawo umoya afanela izinhlelo ezivaliwe ngaphandle kwezidingo zokufaka ama-pig.

Umehluko Wesakhiwo Nokusebenza

• Umklamo Wemigodi Yomoya:

Umoya ophumayo:Imbobo (elingana nosayizi ojwayelekile) kudiski engezansi. Ivuleke ngokuphelele = imbobo ihambisana nesihlalo ukuze kuncishiswe ukugeleza/ukucindezeleka.

Okungangenisi umoya:Akukho mbobo. Umsele wesihlalo uvezwa ezindlebeni uma uvuliwe.

• Ukuvikelwa Kwesivalo:

Umoya ophumayo:Imbobo ihlala ivikela izihlalo ekugugulekeni kwemidiya eqondile, okwandisa isikhathi sokuphila.

Okungangenisi umoya:Izihlalo zingase ziguge uma zivuliwe; ukuthembeka kwazo kuphansi.

Izimo Zohlelo Lokusebenza

Izinzuzo Zokusebenza

•Ukuqeda Ukucindezeleka: Kuvula umoya ongaphakathi kwengcindezi phezulu, kuvimbele ukucindezeleka ngokweqile ekukhuleni kwemidiya.

•Ukusebenza Kahle Kokugeleza: Ukwehla kwengcindezi okuphansi okunendlela yokugeleza ebushelelezi (kufanelekile uwoyela ongahluziwe, igesi yemvelo).

•Ukulungisa: Ukuhlanza i-Pigging kususa amapayipi agciniwe, kunciphisa isikhathi sokungasebenzi.

Izici Zesakhiwo

•Isakhiwo Sokuvala: Izivalo ze-O-ring + izihlalo ezintantayo ezilayishwe kusengaphambili zivumela ukuvala okuqondiswayo. I-torque yokusebenza iphansi ngo-50% kunezivalo ezijwayelekile.

•Isakhiwo Sokupakisha: Ukupakisha okuzivalayo kudinga ukulungiswa okuncane. Ukusebenza okulula nokuvala okuthembekile. Ukufakwa kwamafutha okusizayo kuqinisekisa ukuthi akukho ukuvuza.

•Umklamo Wendlela Yokugeleza: Indlela yokugeleza eqondile egcwele inciphisa ukulahleka kwengcindezi. Isekela ukugoba kwamapayipi.

•Idivayisi Yokuqeda Ukucindezeleka: Ivimbela umonakalo wangaphakathi wokucindezeleka ngokweqile.

•Ukuhlukaniswa:

NgeDrayivu:Kwenziwe ngesandla, Okusebenzisa umoya, Okusebenza ngogesi.

Ngomsebenzi:I-Oilfield, i-Oilline, i-Oilline, i-Gas.

Izinkambu Zohlelo Lokusebenza

→Uwoyela negesi: Amavalvu amakhulu okudlulisa igesi eluhlaza/yemvelo (kufika ku-15.0MPa). Asetshenziswa ezinhlelweni zokudonsa umoya kanye nendawo yokugcina izinto. Ihambisana ne-API 6D.

→Imboni Yamakhemikhali: Ilawula imidiya ebolile (ama-asidi, ama-slurries) isebenzisa izivalo ze-PTFE/graphite.

→Imboni Yamandla: Ilawula ukugeleza kwamanzi/kwentuthu epholile ezitshalweni ezishisayo, zenuzi kanye nezamanzi. Ithuthukisa ukusebenza kahle kwamandla.

→Umasipala kanye Nezemvelo: Ulawula amanzi angcolile/igesi ezinhlelweni zokuhlanza/zokukhipha amanzi. Kusetshenziswa ekuhlinzekweni kwamanzi/ekukhipheni amanzi.

→Ezinye Izimboni: Ukudluliselwa kwensimbi okuhlanzekile kakhulu (i-metallurgy), ukuhlukaniswa kwemidiya engcolile (i-pharma), ukulawulwa koketshezi oluhlanzekile (ukudla).

Izinzuzo kanye nokungalungi

Izinzuzo

1. Ukumelana Nokugeleza Okuphansi: Umklamo oqondile ogcwele imbobo ≈ ukumelana kwesigaba samapayipi amafushane. Umthamo wokugeleza ophezulu.

2. Ukuvala Okuhle Kakhulu: Amadiski okuvala kabili (insimbi + isihlalo esithambile esihlanganisiwe) aqinisekisa ukuvalwa okuqinile. Aphatha ukuguquguquka kwengcindezi/kwezinga lokushisa.

3. Isakhiwo Esilula: Ukukhiqiza nokunakekela okulula. Izindleko eziphansi zomjikelezo wokuphila.
