Ukukhetha nendawo yama-valve

1, Ukukhetha i-valve nendawo yokubeka: (1) Ama-valve asetshenziswa epayipini lokuphakela amanzi ngokuvamile akhethwa ngokuvumelana nalezi zimiso ezilandelayo: 1. Uma ububanzi bepayipi bungekho ngaphezu kuka-50mm, i-valve yokumisa kufanele isetshenziswe. Uma ububanzi bepayipi bukhulu kuno-50mm, ivelu yesango kanye ne-butterfly valve kuzosetshenziswa 2. Lapho ukugeleza nokucindezela kwamanzi kudingeka kulungiswe, i-valve elawulayo kanye ne-valve yokumisa kufanele kusetshenziswe 3. I-valve yenqama kufanele isetshenziselwe izingxenye ezincane. ukumelana namanzi (njengasepayipini lokumunca iphampu lamanzi) 4. Ivalve yesango kanye nevalve uvemvane kufanele kusetshenziswe engxenyeni yepayipi lapho ukugeleza kudinga ukugeleza ngezindlela ezimbili, futhi ivalvu yokumisa akufanele isetshenziswe 5. Ivalve yovemvane nevalve yebhola kufanele zisetshenziselwe izingxenye ezinendawo encane yokufaka 6. Ivalvu yokumisa kufanele isetshenziselwe ingxenye yepayipi evame ukuvulwa futhi ivalwe 7. Amavalvu emisebenzi eminingi kufanele asetshenziswe epayipini lokuphuma lepompo elinomthamo omkhulu (2) Amavalvu kufanele kuhlinzekwe ngalezi zingxenye ezilandelayo zepayipi eliphakela amanzi: 1. Ipayipi lokuphakela amanzi ezindaweni zokuhlala lisuka engxenyeni yepayipi lepayipi eliphakela amanzi likamasipala 2. Indawo yoxhaxha lwamapayipi ayindandatho yangaphandle endaweni yokuhlala kufanele ibekwe ngokwezidingo ze ukwehlukana. Uma ingxenye yepayipi le-annular iyinde kakhulu, kuyancomeka ukuthi umise i-valve yesigaba 3. Ingxenye yokuqala yepayipi legatsha noma indawo yokuqala yepayipi elixhumayo elisuka epayipini elikhulu lokuphakela amanzi lezindawo zokuhlala 4. Ipayipi lasendlini, imitha yamanzi kanye isikhuphukeli segatsha ngasinye (iphansi kwesikhuphukeli kanye nengxenye engenhla nengezansi yesikhuphukeli senethiwekhi yamapayipi annular) 5. Ipayipi elikhulu lenethiwekhi yepayipi eliyiringi kanye nepayipi elixhumayo ngenethiwekhi yamapayipi egatsha 6. Indawo yokuqala yepayipi yokusabalalisa exhunywe endlini. ipayipi elihambisa amanzi endlini, endlini yangasese yomphakathi, njll. lizosethwa lapho indawo yokusabalalisa epayipini legatsha lokusabalalisa lingaphezu kwama-3 7. Ipayipi lokuphuma kwamanzi lephampu yamanzi, iphampu yokudonsa yepompo ezizigcwalisayo 8. Amapayipi okungena naphuma amanzi namapayipi okuchitha amathangi amanzi 9. Amapayipi angenisa amanzi kanye nawokwenza izinto zokusebenza (njengehitha, umbhoshongo wokupholisa, njll.) 10. Amapayipi okusabalalisa izinto zikagesi zangasese (njengamakhulu, izindawo zokuchamela, izitsha zokugezela, amashawa, njll.) 11. Ezinye izesekeli, njenge-automatic exhaust valve, i-pressure relief valve, i-hammer eliminator yamanzi, i-pressure gauge, i-sprinkler, njll., i-valve yokunciphisa ingcindezi kanye ne-backflow preventer, njll. 12. Ingxenye ephansi kakhulu yenethiwekhi yokuphakelwa kwamanzi kufanele ifakwe ukukhishwa kwamanzi. i-valve (3) Ngokuvamile, i-valve yokuhlola izokhethwa ngokusho kwendawo yokufaka, ingcindezi yamanzi phambi kwe-valve, izidingo zokusebenza zokuvala uphawu emva kokuvala nosayizi wesando samanzi okubangelwa ukuvala 1. Uma ukucindezela kwamanzi kuphambi kwe-valve, jika , ama-valve okuhlola amabhola kanye ne-shuttle kufanele akhethwe 2. Uma ukusebenza kokuvala emva kokuvala kuqinile, kunconywa ukukhetha i-valve yokuhlola nge-spring yokuvala 3. Uma kudingekile ukuba buthaka isando samanzi sokuvala, kunconywa ukuba ukhethe Ukuvala ngokushesha ivalvu yokuhlola ukuthulisa noma i-valve yokuhlola ukuvala kancane enomshini wokumanzisa 4. I-valve ye-valve noma umgogodla we-valve ye-valve yokuhlola uzokwazi ukuzivala ngokwawo ngaphansi kwesenzo samandla adonsela phansi noma entwasahlobo (4)) Amavalvu okuhlola azohlinzekwa izingxenye ezilandelayo zepayipi lokuphakela amanzi: Epayipini elingenisa amanzi; ku-heater yamanzi evaliwe noma impahla yamanzi; epayipini lokuphuma kwepompo lamanzi; epayipini lokuphuma lethangi lamanzi, umbhoshongo wamanzi kanye nechibi lasezintabeni lapho indawo yokungena amanzi namapayipi aphumayo ahlanganyela ipayipi elilodwa. Qaphela: ingxenye yepayipi ene-pipe backflow preventer ayidingi ukufaka i-valve yokuhlola. (5) Imishini yokukhipha umoya kufanele ihlinzekwe ezingxenyeni ezilandelayo zepayipi lokuphakela amanzi: 1. Kuhleloxhumano lokuphakela amanzi ngezikhathi ezithile, ivalvu yokukhipha umoya ezenzakalelayo kufanele isethwe ekugcineni nendawo ephakeme kakhulu yenethiwekhi yamapayipi 2. Inethiwekhi yokuphakelwa kwamanzi isobala ukushintshashintsha nokuqoqwa komoya endaweni yepayipi, kanye nevalvu yokukhipha igesi ezenzakalelayo noma ivalve eyenziwa ngesandla isethwe endaweni ephakeme kakhulu yesigaba ukuze ikhiphe 3. Uma ithange lamanzi elinomfutho womoya elizenzakalelayo lisetshenziselwa idivayisi yokuphakela amanzi ngomfutho womoya, indawo ephakeme kakhulu yoxhaxha lokusatshalaliswa kwamanzi kufanele ifakwe i-automatic exhaust valve
