Ukuhlaziywa Kwezinzuzo Nokungalungile Kwezinhlobo Ezinhlanu Ezivamile Zama-Valve 2

3. I-Ball Valve

I-valve yebhola yavela ku-valve yepulaki. Ingxenye yayo yokuvula nokuvala iyindilinga, futhi indilinga ijikeleza ngama-90° izungeze i-axis yesiqu se-valve ukuze kufezwe injongo yokuvula nokuvala. I-valve yebhola isetshenziswa kakhulu kumapayipi ukusika, ukusabalalisa, nokushintsha indlela yokugeleza kwe-medium. I-valve yebhola eklanywe ngokuvulwa okunobume obungu-V nayo inomsebenzi omuhle wokulawula ukugeleza.

Ifektri ye-TWS valve inikeza i-valve ye-butterfly ehlala isikhathi eside e-wafer YD37A1X3-16Q, i-Double flanged concentric butterfly valveD34B1X3-16Q, Ivalvu yebhabhathane engavamile ephindwe kabili ngokwe-Ser.13 noma uchungechunge 14, ivalvu yesango elihlala irabha ye-BS5163/F4/F5 /ANSI CL150, i-Y-strainer, ivalvu yokulinganisela, isivimbeli sokugeleza emuva.

3.1 Izinzuzo:

① Inokumelana nokugeleza okuphansi kakhulu (cishe u-0).

② Njengoba ingeke ibambeke ngesikhathi sokusebenza (uma kungekho lubricant), ingasetshenziswa ngokuthembekile ezindaweni ezibolile kanye nasezintweni ezimanzi ezibila kancane.

③ Ingafinyelela ukuvala okuphelele ngaphakathi kwebanga lokucindezela nokushisa elikhulu.

④ Ingafinyelela ukuvulwa nokuvalwa okusheshayo. Isikhathi sokuvula nokuvala kwezinye izakhiwo singamasekhondi angu-0.05 kuya kwangu-0.1 kuphela, okuqinisekisa ukuthi ingasetshenziswa ezinhlelweni ezizenzakalelayo zamabhentshi okuhlola. Lapho ivula futhi ivala ivalvu ngokushesha, akukho mthelela ngesikhathi sokusebenza.

⑤ Ingxenye yokuvala eyindilinga ingahlala ngokuzenzakalelayo endaweni yomngcele.

⑥-- Indawo yokusebenza ivalwe ngokuthembekile ku-valve.

Q⑦ Uma ivalvu ivuliwe ngokuphelele futhi ivaliwe ngokuphelele, izindawo zokuvala zesphere kanye nesihlalo sevalvu ziyahlukaniswa nendawo yokuvala. Ngakho-ke, indawo yokuvala egeleza ngevalvu ngesivinini esikhulu ngeke ibangele ukuguguleka kwezindawo zokuvala.

⑧ Inesakhiwo esincane kanye nesisindo esincane. Ingabhekwa njengesakhiwo sevalvu esifanelekile kakhulu sezinhlelo ezisezingeni eliphansi lokushisa.

⑨ IivalvuUmzimba ulingana. Ikakhulukazi ngesakhiwo somzimba sevalvu ehlanganisiwe, ungamelana kahle nokucindezeleka okuvela epayipini.

⑩ Ingxenye yokuvala ingamelana nomehluko wokucindezela okuphezulu ngesikhathi sokuvala.

⑪ Ivalvu yebhola enomzimba wevalvu ohlanganisiwe ngokuphelele ingangcwatshwa ngqo ngaphansi komhlaba, ivikele izingxenye zangaphakathi zevalvu ekugqwaleni. Isikhathi sayo esiphezulu senkonzo singafinyelela eminyakeni engama-30, okwenza ibe yivalvu efanelekile kakhulu yamapayipi kawoyela negesi yemvelo.

3.2 Okubi:

① OkuyinhlokoivalvuIzinto zokuvala isihlalo ze-valve yebhola yi-polytetrafluoroethylene (PTFE). Ayisebenzi cishe kuzo zonke izinto zamakhemikhali futhi inezici eziphelele ezifana ne-coefficient encane yokungqubuzana, ukusebenza okuzinzile, ukumelana nokuguga, ububanzi bokushisa obusebenzayo, kanye nokusebenza okuhle kakhulu kokuvala. Kodwa-ke, izakhiwo zomzimba ze-PTFE, okuhlanganisa i-coefficient ephezulu yokwanda, ukuzwela ekugelezeni okubandayo, kanye nokuqhuba kahle kokushisa, kudinga ukuthi ukwakheka kwe-valve seat seal kumele kwenziwe ngalezi zakhiwo. Ngakho-ke, lapho izinto zokuvala ziqina, ukuthembeka kwe-seal kuyaphazamiseka. Ngaphezu kwalokho, izinga lokumelana nokushisa le-PTFE liphansi kakhulu, futhi lingasetshenziswa kuphela emazingeni okushisa angaphansi kuka-180°C. Lapho izinga lokushisa lidlula leli nani, izinto zokuvala zizoguga. Uma kucatshangelwa ukusetshenziswa kwesikhathi eside, ngokuvamile kusetshenziswa kuphela ku-120°C.

② Ukusebenza kwayo kokulawula kubi kancane kunokwe-globe valve, ikakhulukazi kuma-pneumatic valve (noma ama-electric valve).

5. I-Plug Valve

I-valve yepulaki ibhekisela ku-valve ejikelezayo lapho ingxenye yokuvala isesimweni se-plunger. Ngokujikeleza ngo-90°, ukuvulwa kwendlela epulaki kwenziwa ukuze kuxhumane noma kuhlukaniswe nokuvulwa kwendlela emzimbeni we-valve, kufezwe ukuvulwa noma ukuvalwa kwe-valve. Ibizwa nangokuthi i-cock, i-stopcock, noma i-rotary gate. Ukuma kwe-plug kungaba yi-cylindrical noma i-conical. Kunezinhlobo eziningi zayo, kufaka phakathi uhlobo oluqondile, uhlobo lwezindlela ezintathu, kanye nohlobo lwezindlela ezine. Isimiso sayo sifana kakhulu nolwe-ball valve.

5.1 Izinzuzo:

① Ifanele ukusetshenziswa njalo, ivuleka futhi ivale ngokushesha nangokulula.

② Ukumelana noketshezi kuncane.

③ Inesakhiwo esilula, inomthamo omncane, isisindo esincane, futhi kulula ukuyinakekela.

④ Isebenza kahle ekuvaleni.

⑤ Njengoba ingavinjelwanga yindlela yokufaka, indlela yokugeleza kwe-medium ingaba ngokungahleliwe.

⑥ Akukho ukudlidliza, futhi umsindo uphansi.

5.2 Okubi:

⑦ Indawo yokuvala inkulu kakhulu, okubangela i-torque eningi kakhulu kanye nokuguquguquka okwanele.

⑧ Uma ithintekile isisindo sayo, ubukhulu be-valve bunqunyelwe.

Ekusetshenzisweni kwangempela, uma kudingeka ivalvu enkulu, kufanele kusetshenziswe isakhiwo sepulaki ebuyela emuva, okungenzeka ukuthi sithinte umphumela wokuvala.
