✧ Incazelo
Imishini inobuqili obuqinile obuphephile futhi obuthembekile, inyunyana iphela ngesihlalo se-valve yesango nesango libekwe uphawu lwensimbi esebenzisa ukubekwa uphawu kwensimbi, futhi kube lula ukuvula, amaphethelo amabili e-valve namapayipi axhunyiwe ngokunyakaza okuyindilinga. Ukuxhumeka okushukumisayo kwendandatho ye-rubber seal efana ne- "O" akusona isidingo esiphakeme ngokuqondile kwamaphethelo womabili amapayipi, ukusebenza kwalo seal kulungile kakhulu ngemuva kokufakwa ngemuva.
I-VUD yesango lesango, elinomklamo ophakeme umsebenzi wokunemba ubuhlakani kanye nomgomo ofakazelwe ngzonke ahlangabezana nezidingo zokumba ezinokhahlo enkundleni yanamuhla kawoyela.
I-valve ivumelana nobukhulu obujwayelekile be-flange kanye nokulinganisa ingcindezi kwengcindezi yokusebenza kwe-3000 ne-5000 PSI yokusebenza, usayizi ojwayelekile ngu-2 ", 3", insizakalo yokushisa kuze kube ngu-400 ° F.
Ukuxhumeka kokuphela kwe-Flanged-Mand-Lolu hlobo lokuxhumeka kokuphela aludingi ukuguqulwa noma ukushelela i-valve. Ama-flanges ahlanganisiwe e-RTJ axhunyiwe kumaphayiphu wepayipi ngama-bolts namantongomane.
Ukuxhumeka kokuphela okuhlanganisiwe - lolu hlobo lokuxhumeka kokuphela, futhi luphethwe njenge-screw, lufanele izinhlelo zokusebenza ezifika ku-7500psi. I-Line Pipe (LP) nemicu engu-8 iyatholakala.
Ukuxhumeka kokuphela kwe-Butt Weld - Lolu hlobo lokuxhumana kokuphela lukhiqizwa ukufanisa uxhumano lwe-Pip Weld. Imikhawulo emibili ebekiwe iboshelwe ndawonye futhi ifakwe endaweni. Ukuxhumeka kwe-Welded kulungele izinhlelo zokusebenza lapho kukhishwa khona ipayipi.
Isexwayiso se-Welding: Ngaphambi kokufudumala, isihlalo sesihlalo nophawu lwe-bonnet kumele lususwe emzimbeni we-valve.
