I-Parallel Slide Gate Valve: Isikhokelo sokugqibela seempawu, iintlobo kunye nezicelo

Yintoni iValve yeSango leSilayidi eliParallel

I-Parallel Slide Gate Valve yivalvu etyibilikayo elawula ukuvulwa/ukuvalwa ngeediski zesango ezityibilikayo. Ilungu layo lokuvala (idiski yesango) lineendawo zokutywina ezicwebezelayo nezithe tyaba ezihambelana kakuhle nesihlalo, ezisetyenziselwa ikakhulu ukuvala okanye ukuqhagamshela ukuhamba kwemidiya.

Umgaqo Wokusebenza

Ivalvu yesango elihambahambayo isebenzisa isakhiwo sediski esihambahambayo esiphindwe kabini. Indlela yokuqhuba ihambisa isango ngokuthe nkqo ukuze ivule/ivale indlela yolwelo. Isango linembobo elingana nobubanzi bangaphakathi bombhobho. Ukujikeleza ivili lesandla okanye ukusebenzisa i-actuator kuphakamisa/kwehlisa isiqu kunye nesango. Xa imbobo yesango ihambelana nombhobho, ulwelo luyahamba (ivalufa iyavuleka). Xa isango livala indlela yokuhamba (imbobo ibuyele kwigumbi levalvu), ivalvu iyavalwa.

Izinto ezibalulekileyo zeeValve zeSango leSilayidi eziParallel

Idiski yoMzimba weValve kunye neSango

Umzimba wenziwe ngentsimbi yekhabhoni, intsimbi engatyiwayo, njl.njl., enendawo yeediski zesango ezihambelanayo. Uyilo lweediski ezimbini luphucula ukutywinwa. Intshukumo yediski ethe nkqo ilawula ukuhamba.

I-Stem kunye ne-Sealing Assembly

Isiqu (i-alloy/intsimbi engatyiwayo) siqhagamshela kwisango ngemisonto. Izinto zokutywina ziquka izihlalo ze-alloy eziqinileyo, i-PTFE, okanye iiringi ze-graphite eziqinisekisa ukutywinwa kwecala ngalinye.

Indlela yokuqhuba

Ii-Actuators ziyahambelana nemigangatho ye-API 6D, exhasa ukusebenza ngesandla, ngombane, okanye ngomoya. Kukho iindlela zokuthintela ukuqhuma.

Ulwakhiwo lokutywina

Inezihlalo ezidadayo ezinokufakwa kwangaphambili ukuze zitywinwe kwicala ngalinye. Izinto ezisetyenziswayo: igrafiti eqinisiweyo, i-PTFE.

Ezinye Izinto Ezibalulekileyo

I-Yoke Sleeve: I-aluminium bronze inciphisa i-torque yokusebenza.

Indandatho Yesihlalo: Idityaniswe ukuze kube lula ukuyilungisa.

Iivalvu zeSango leSlide eziVulwayo kunye neziNgenazo iiVenkile

Umahluko ophambili usekwe kwisakhiwo, umsebenzi, kunye nokusetyenziswa. Iivalvu ezivulela umoya zinomngxuma wokunciphisa uxinzelelo, ukugquma, kunye nokukhusela isihlalo kwimibhobho emide. Iivalvu ezingenayo imingxunya zilungele iinkqubo ezivaliweyo ngaphandle kweemfuno zokugquma.

Umahluko kwiSakhiwo kunye neMisebenzi

• Uyilo lweMingxunya yoVula:

Umoya ovuthuzayo:Umngxuma (olingana nobukhulu obuqhelekileyo) kwidiski esezantsi. Ivuleke ngokupheleleyo = umngxuma uhambelana nesihlalo sokukhulula ukuhamba/uxinzelelo.

Ayinamoya:Akukho mngxuma. Umngxuma wesihlalo uvezwa kwimidiya xa uvuliwe.

• Ukhuseleko lweSitywina:

Umoya ovuthuzayo:Umngxuma uhlala ukhusela izihlalo ekukhukulisekeni kwemidiya ngqo, nto leyo eyandisa ubomi bazo.

Ayinamoya:Izihlalo zinokubola xa zivuliwe; ukuthembeka kwazo akusenakwenzeka.
