3. Ivalvu yebholo
Ivalvu yebholo yavela kuvalvu yeplagi. Ingcenye yayo yokuvula nokuvala yi-sphere, begodu i-sphere ijikeleza nge-90° ukuzombeleza i-eksisi yesiqu sevalvu ukufikelela umnqopho wokuvula nokuvala. I-valve yebholo isetjenziswa khulu emaphayiphini ukusika, ukusabalalisa, nokutjhugulula indlela yokugeleza kwe-medium. Ivalvu yebhola eyakhiwe ngokuvuleka okufana ne-V nayo inomsebenzi omuhle wokulawula ukugeleza.
Ifemu ye-TWS valve inikela nge-valve ye-butterfly ye-wafer eqinileko YD37A1X3-16Q, i-Double flanged concentric butterfly valveD34B1X3-16Q, Ivalvu ye-butterfly ye-double flanged eccentric ngokuya nge-Ser.13 nofana i-series 14, i-BS5163/F4/F5 /ANSI CL150 i-rabber seated gate valve, i-Y-strainer, i-balancing valve, i-back flow preventer.
3.1 Iinzuzo:
Inokujamelana nokugeleza okuphasi khulu (pheze 0).
Njengombana ingekhe ibambeke ngesikhathi sokusebenza (nangabe kungekho ukuthambisa), ingasetjenziswa ngokuthembeka eendaweni ezibolako kanye namanzi anezinga eliphasi lokubilisa.
Ingafinyelela ukuvala okupheleleko ngaphakathi kwezinga elikhulu lokugandeleleka kanye namazinga womtjhiso.
Ingakghona ukuvula nokuvala msinyana. Isikhathi sokuvula nokuvala kwezinye izakhiwo siyi-0.05 ukuya ku-0.1 imizuzwana, okuqinisekisa bona singasetjenziswa eenhlelweni ezizenzakalelayo zamabhanka wokuhlola. Lokha nawuvula begodu uvala ivalvu msinyana, akukho umthelela ngesikhathi sokusebenza.
Ihlangothi lokuvala eliyindilinga lingahlala ngokuzenzakalelako endaweni yomngcele.
⑥-- Indawo yokusebenza ivalwe ngokuthembekileko ku-valve.
Q6 Lokha ivalvu nayivulekile begodu ivaliwe ngokupheleleko, iindawo zokuvala zebhola nesihlalo sevalvu zihlukaniswe phakathi. Ngalokho-ke, umphakathi ogeleza nge-valve ngebelo elikhulu angeze wabanga ukuguguleka kwendawo yokuvala.
Inesakhiwo esincani nesisindo esilula. Ingathathwa njengesakhiwo sevalvu esizwakalako khulu seenhlelweni eziphakathi nendawo ezinezinga lokutjhisa eliphasi.
Iivalvuumzimba uyalingana. Khulukhulu ngesakhiwo somzimba wevalvu, ingakghona ukujamelana nokugandeleleka okuvela epayipini.
Ingcenye yokuvala ingakghona ukujamelana nomehluko omkhulu wokugandeleleka ngesikhathi sokuvala.
⑪ Ivalvu yebholo enomzimba wevalvu ohlanganiswe ngokupheleleko ingangcwatshwa ngqo ngaphasi komhlaba, ivikele iingcenye zangaphakathi zevalvu ekugqwaleni. Isikhathi sayo esiphezulu sokusebenza singafinyelela eminyakeni ema-30, okwenza bona ibe yi-valve ehle khulu yamapayipi we-oli negesi yemvelo.
3.2 Ububi:
Into ekuluivalvuindandatho yokuvala isihlalo yevalvu yebholo yi-polytetrafluoroethylene (PTFE). Ayingeneli pheze kizo zoke izinto zamakhemikhali begodu ineemfanelo ezifana ne-friction coefficient encani, ukusebenza okuzinzileko, ukujamelana nokuguga, ibanga elibanzi lokutjhisa elisebenzako, nokusebenza okuhle khulu kokuvala. Kodwana, ubujamo obubonakalako be-PTFE, okufaka hlangana i-coefficient ephezulu yokunwebeka, ukuzwela ukugeleza okubandako, nokudlulisa ukutjhisa okumbi, kutlhoga bona ukuklanywa kwesivalo sesihlalo sevalvu kufanele kwenziwe eduze nezakhiwo lezi. Ngalokho-ke, lokha into yokuvala nayiqina, ukuthembeka kokuvala kuyaphazamiseka. Ngaphezu kwalokho, izinga lokujamelana nokutjhisa kwe-PTFE liphasi, begodu lingasetjenziswa kwaphela emazingeni womtjhiso angaphasi kwe-180°C. Lokha amazinga womtjhiso adlula inani leli, into yokuvala izokuguga. Nakuqalwa ukusetjenziswa kwesikhathi eside, kuvamise ukusetjenziswa kwaphela ku-120°C.
Ukusebenza kwayo kokulawula kumbi khulu kunaleyo ye-globe valve, khulukhulu ema-valve we-pneumatic (nofana ama-valve wegezi.
5. Plaga ivalvu
Ivalvu yepulagi itjho ivalvu ejikelezako lapho ingcenye yokuvala inesimo sepulanga. Ngokujika 90°, ukuvuleka kwendlela epulagini kwenziwa bona kukhulumisane nofana kuhlukaniswe nokuvuleka kwendlela emzimbeni wevalvu, ukufikelela ukuvulwa nofana ukuvalwa kwevalvu. Ibizwa nangokuthi yi-cock, i-stopcock, nofana isango elijikelezako. Ubujamo bepulaki bungaba buyisilinda nofana bube yikhoni. Kunemihlobo eminengi yayo, okufakahlangana umhlobo oqondileko, umhlobo oneendlela ezintathu, kanye nomhlobo oneendlela ezine. Umthetho wayo ufana khulu newevalvu yebholo.
5.1 Iinzuzo:
Ilungele ukusetjenziswa kanengi, ngokuvulwa nokuvala okurhabako nokulula.
Ukujamelana noketshezi kuncani.
Inesakhiwo esilula, ivolumu encani, isisindo esilula, begodu kulula ukuyitlhogomela.
Inokusebenza okuhle kokuvala.
Akuvinjelwe yindlela yokufaka, indlela yokugeleza kwe-medium ingaba ngokungakhethi.
Akukho ukudlidliza, begodu umsindo uphansi.
5.2 Ububi:
Indawo yokuvala inkulu khulu, okurholela ekutheni kube ne-torque enengi khulu nokungatjhuguluki okwaneleko.
⑧ Ithintwa bunzima bayo, ubukhulu be-valve diameter bulinganiselwe.
Ekusetjenzisweni kwamambala, nangabe ivalvu ekulu iyatlhogeka, kufanele kusetjenziswe isakhiwo sepulagi esibuyela emuva, okungenzeka bona kuthinte umphumela wokuvala.
Imininingwana eminengi, ungayithinta simahlaIvalvu ye-TWSifekthri.
