Yini inqubo yokukhetha yama-valves

Izindlela zokukhetha i-Valve: Ukucatshangelwa kobukhulu obuningi ukuqinisekisa ukuhambisana kohlelo

Ukukhetha i-valve kufanele kubhekwe izici eziningi zokuhlangabezana nezidingo zokusebenza okuphephile, ezinzile, nokusebenza kahle kohlelo. Izindlela zokukhetha ezibalulekile zimi ngokulandelayo:

Izici eziyi-1.FLUID

Uhlobo lwe-Fluid: Ngamagesi, amagesi ajwayelekile angakukhetha ama-valve e-Gate, ama-valves e-njll. Amagesi ahlanganayo futhi aqhumayo kufanele akhethwe ngokubekwa kahle kukaBeaning kanye nokumelana nomlilo kanye nokuphikiswa, okufana nama-valve ebhola anezinhlaka ezilwa nomlilo. Ngokuya koketshezi, kunezinketho ezahlukahlukene zamanzi ahlanzekile; Ngoketshezi oluqukethe izinhlayiya eziqinile, ama-valve avimbela ukugqoka njengama-plug valve kufanele akhethwe ukuvikela ukugqoka nokuvinjwa; Ama-Complocinage uketshezi adinga ama-valve enziwe ngezinto zokulwa nokugqwala, njengensimbi engenasici nama-valves angenabala kanye nama-valve epulasitiki, kuya nge-medium.

Ukushisa kwe-fluid: Amanzi aphezulu okushisa (ngenhla kwama-450 ℃) kufanele akhethe ama-valve amelana namazinga okushisa aphezulu, njenge-chromium molybdenum steel ama-valves aphakathi kwesango lokushisa elisetshenziswa kumapayipi okushisa. Ama-fluids okushisa aphansi (ngezansi -40 ℃) adinga ama-valves anokulimala okuhle okushisa, nama-valves okushisa aphansi avame ukusetshenziswa ku-nitrogen ye-nitrogen ne-liquid oksijini.

Ingcindezi ye-fluid: Amanzi aphansi aphansi (ngaphansi kwe-1.6MPA), ama-valve ebanga elijwayelekile angakhethwa; I-High Pressure Fluids (Ingcindezi Ephakathi ne-1.6-10MPA, ingcindezi ephezulu enkulu kune-10MPA) idinga ukusetshenziswa kwama-valves aphezulu wengcindezelo, njengama-valve asuka phezulu.

· I-fluid viscosisite: uketshezi oluphansi lwe-viscoids lunezinketho eziningi zokukhethwa; Uketshezi oluphezulu lwe-viscofity luthambekele ekunamathelayo kanye nokuvinjelwa, ngakho-ke kuyadingeka ukukhetha ama-valves wesango kanye nama-valve ebhola anomthamo ophakeme wokugeleza kanye nokuvinjelwa okuphansi. Uma kunesidingo, afakazeleki kagesi noma ama-pneumatic kufanele asetshenziswe.

Umsebenzi we-2.process

· Sika umsebenzi I-valve evaliwe ivalwe kahle futhi ilungele izikhathi ezinezidingo eziphezulu zokubekwa uphawu; I-Valve Valve ishintsha ngokushesha futhi ibeka uphawu ngokuthembekile, ilungele ukuvula njalo nokuvala; Ama-butterfly ama-valves anesakhiwo esilula nevolumu elincane, elenza lilungele amapayipi aphansi aphansi.

· Umsebenzi wokulungiswa Kunezinhlobo ezifana nesihlalo esisodwa, isihlalo esiphindwe kabili, kanye nama-valves alawulwa yi-Sleeve.

· Umsebenzi wokuhlola Ama-Swing Check Valves anokumelana okuphansi koketshezi futhi alungele ububanzi obukhulu bokufakwa okuvundlile.

Umsebenzi Wokuvikelwa Kwezokuphepha: I-Valve yezokuphepha ivimbela imishini noma ingcindezi yepayipi kusuka kunani elishiwoyo, futhi ivule ngokuzenzakalela ukukhipha uketshezi lapho ingcindezi ephezulu kakhulu; I-burding disc iyithuluzi lokuphepha elahla elilahlayo eliqhuma futhi likhiphe uketshezi lapho ingcindezi ifinyelela inani lokuqhuma.
