Ukukhethwa nokusetha ingxenye yevalvu yendlela yokulungiselela imodeli yedivayisi kagesi yevalvu
1. Uma ububanzi bepayipi bungakhudlwana kuno-50mm, i-valve yeglobe kufanele isetshenziswe; lapho ububanzi bepayipi bukhulu kuno-50mm, i-valve yesango ne-butterfly valve kufanele isetshenziswe; 2. Lapho izinga lokugeleza lidinga ukulungiswa, ukucindezela kwamanzi kufanele kulungiswe ngokulawula i-valve ne-globe valve.
Umgomo wokukhetha ama-valve azosetshenziswa kumapayipi okuhambisa amanzi
1. Uma ububanzi bepayipi bungaphansi kuka-50mm, i-valve yeglobhu kufanele isetshenziswe. Uma ububanzi bepayipi bukhulu kuno-50mm, i-valve yesango ne-butterfly valve kufanele isetshenziswe
I-2, idinga ukulungisa ukugeleza, ingcindezi yamanzi kufanele isebenzise i-valve yokulawula, i-valve yokumisa
3. Amavalvu esango kufanele asetshenziswe lapho ukumelana nokugeleza kwamanzi kukuncane (njengepayipi lokumunca iphampu yamanzi)
4. I-valve yesango kanye ne-butterfly valve izosetshenziswa engxenyeni yepayipi lapho ukugeleza kwamanzi kunezindlela ezimbili, futhi ivalve yokumisa ngeke isetshenziswe.
5. I-valve ye-Butterfly ne-valve yebhola kufanele isetshenziselwe indawo encane yokufaka
6. Engxenyeni yepayipi evame ukuvulwa futhi ivaliwe, i-valve yokumisa kufanele isetshenziswe
7, ipayipi lokuphuma lephampu lamanzi elinesikali esikhulu kufanele lisebenzise ivalvu enezinto eziningi
(2) Ukuma kwevalvu epayipini lokuphakela amanzi
1. Ipayipi lokuphakela amanzi lesifunda okuhlalwa kuzo lisuka engxenyeni yamapayipi ehamba phambili yepayipi likamasipala lokuphakela amanzi
2. Ama-node wenethiwekhi yamapayipi ayindilinga yangaphandle ezindaweni zokuhlala kufanele abekwe ngokuvumelana nezidingo zokuhlukaniswa. Uma ingxenye yepayipi ye-annular yinde kakhulu, ama-valve ahlukene kufanele asethwe
3, kusukela epayipini elikhulu lokuhlinzeka ngamanzi ezindaweni zokuhlala kusukela ekuqaleni kwepayipi legatsha noma ekuqaleni kwepayipi lasendlini
4. Ipayipi lasendlini, imitha yamanzi kanye nesikhuphukeli segatsha ngasinye (phansi kwesikhuphukeli, ingxenye engaphezulu nengezansi yesikhuphukeli senethiwekhi yamapayipi ayindandatho aqondile)
I-5, ipayipi legatsha lenethiwekhi yepayipi, ipayipi elixhumayo ngenethiwekhi yepayipi legatsha
6, ipayipi lokuhambisa amanzi endlini ezindlini, ezindlini zangasese zomphakathi, njll. kusukela ekuqaleni kwepayipi lokusabalalisa amanzi, amapayipi egatsha okusabalalisa amanzi izindawo zokusabalalisa amanzi kumasethi amathathu nangaphezu kuka-3
7, ipayipi lokuphuma lephampu lamanzi, iphampu yokunisela yokunisela
8. Amapayipi amanzi ethangi lokungena nokuphuma kanye namapayipi okukhipha amanzi
9, izinto zokusebenza (ezifana ne-heater, umbhoshongo wokupholisa, njll.) ipayipi lokugcwalisa amanzi
10, izinto zikagesi ezihlanzekile (ezinjengezinkulu, zokuchamela, indishi yokuwasha, ishawa, njll.) zepayipi lokusabalalisa
I-11, ezinye izesekeli, njenge-automatic exhaust valve, i-valve yokusiza ukucindezela, isinqamuli sesando samanzi, igeji yokucindezela, ibholithi yokufafaza, i-valve yokunciphisa ukucindezela kanye nedivayisi yokuvimbela ukugeleza okubuyela emuva ngaphambi nangemuva.
12. Ivalvu yokukhipha amanzi kufanele isethwe engxenyeni engezansi yenethiwekhi yokuphakelwa kwamanzi
(okuthathu) hlola ukukhetha kwevalvu
Ama-valve okuhlola kufanele akhethwe ngokuya ngendawo yokufaka, ingcindezi yamanzi ngaphambi kwe-valve, izidingo zokusebenza kokuvala ngemva kokuvala kanye nobukhulu besando samanzi esiqaliswe lapho kuvalwa, njll. :
1. Lapho ingcindezi yamanzi ngaphambi kokuba i-valve incane, uhlobo lwe-swing, uhlobo lwebhola kanye ne-shuttle check valve kufanele kukhethwe.
2. Uma ukusebenza kwe-airtight ngemva kokuvala kuyadingeka ngokuqinile, i-valve yokuhlola enentwasahlobo yokuvala kufanele ikhethwe
3. Lapho isando samanzi sidingeka ukuba sibe buthakathaka futhi sivalwe, kungakuhle ukuthi ukhethe i-valve yokuhlola ukuvala ukuvala ngokushesha noma i-valve yokuhlola yokuvala kancane enomshini wokuthambisa.
4, hlola i-valve break noma i-spool, kufanele ikwazi ukuvala ngaphansi kwesenzo samandla adonsela phansi noma amandla entwasahlobo
(4) Amavalvu okuhlola kufanele afakwe emapayipini okuhambisa amanzi
Epayipini; Epayipini lokungena le-heater yamanzi evaliwe noma imishini yamanzi; Epayipini lokuphuma kwepompo lamanzi; Engxenyeni yepayipi lokuphuma ethangini lamanzi, umbhoshongo wamanzi kanye nechibi elikhuphukayo lepayipi elifanayo.
Qaphela: ama-valve okuhlola awadingeki ezingxenyeni zamapayipi anezivimbeli zokubuyela emuva kwamapayipi.
(5) Indawo yomshini wokukhipha amanzi wepayipi lokuphakela amanzi
1, ukusetshenziswa ngezikhathi ezithile kwenethiwekhi yamapayipi okuhambisa amanzi, ukuphela kwenethiwekhi yamapayipi nendawo ephakeme kufanele kusethwe nge-automatic exhaust valve.
2. Ivalvu yokukhipha umoya okuzenzakalelayo noma ivalvu eyenziwa ngesandla isethwe endaweni ephakeme kakhulu yengxenye yepayipi ngokunqwabelana komoya okungenasisekelo kunethiwekhi yokuphakelwa kwamanzi.
I-3, idivayisi yokuhambisa amanzi okucindezela komoya, lapho kusetshenziswa i-othomathikhi yokugcwalisa umoya ithangi lamanzi lomfutho womoya, ukuqhathaniswa kwenethiwekhi yokusabalalisa amanzi kufanele kufakwe i-automatic exhaust valve.
Leli zinga lisebenza ekushayeleni kwezimoto, ekulawuleni ukuthintana kukagesi, i-valve yesango lesivinini esisodwa, i-globe valve, i-drill I valve, i-diaphragm valve, i-valve yebhola, i-plug valve, i-butterfly valve namanye amadivaysi kagesi ama-valve (ngemuva kwalokhu okubizwa ngokuthi amadivaysi kagesi). Ibhishi elilandelayo liqukethe izinhlinzeko, ngokubhekisela kuleli zinga lamazwe ngamazwe, ezihlanganisa izinhlinzeko zaleli zinga lamazwe ngamazwe. Izinhlelo ezibonisiwe zisebenza ngesikhathi sokushicilelwa kwaleli zinga. Wonke amazinga angaphansi kokubuyekezwa futhi amaqembu asebenzisa leli zinga kufanele ahlole ukuthi kungenzeka yini ukusebenzisa izinguqulo ezingu-*** zamazinga alandelayo.
