Kusankha ndi kukhazikitsa gawo la valve ya njira yokonzekera chipangizo chamagetsi cha valve

1. Pamene m'mimba mwake sali wamkulu kuposa 50mm, valavu yapadziko lonse iyenera kugwiritsidwa ntchito; pamene m'mimba mwake chitoliro ndi chachikulu kuposa 50mm, valavu pachipata ndi valavu gulugufe ayenera kugwiritsidwa ntchito; 2. Pamene kuthamanga kwa madzi kumayenera kusinthidwa, kuthamanga kwa madzi kuyenera kusinthidwa ndi valve yoyendetsa ndi globe valve.
Mfundo yosankha ma valve kuti agwiritse ntchito mapaipi amadzi
1. Pamene kukula kwa chitoliro ndi kosakwana 50mm, valavu ya globe iyenera kugwiritsidwa ntchito. Pamene kukula kwa chitoliro ndi chachikulu kuposa 50mm, valavu ya chipata ndi valavu ya butterfly iyenera kugwiritsidwa ntchito
2, muyenera kusintha otaya, kuthamanga kwa madzi kuyenera kugwiritsa ntchito valavu yowongolera, valavu yoyimitsa
3. Mavavu a pachipata akuyenera kugwiritsidwa ntchito pomwe madzi samatha kuyenda pang'ono (monga chitoliro cha pampu yamadzi)
4. Vavu yachipata ndi valavu ya butterfly idzagwiritsidwa ntchito pa chitoliro chomwe madzi akuyenda njira ziwiri, ndipo valavu yoyimitsa siigwiritsidwe ntchito.
5. Vavu ya butterfly ndi valavu ya mpira ziyenera kugwiritsidwa ntchito poika malo ochepa
6. Mu gawo la chitoliro lomwe nthawi zambiri limatsegulidwa ndi kutsekedwa, valve yoyimitsa iyenera kugwiritsidwa ntchito
7, chitoliro chachikulu cha mpope chamadzi chiyenera kugwiritsa ntchito valavu yambiri
(2) Malo a valve paipi yamadzi
1. Mapaipi operekera madzi m'boma lokhalamo amachokera ku gawo lotsogola la mapaipi operekera madzi a tauni
2. Nsonga zapanja zozungulira zozungulira zozungulira m'madera okhalamo ziyenera kukhazikitsidwa malinga ndi zofunikira zolekanitsa. Ngati gawo la chitoliro cha annular ndi lalitali kwambiri, ma valve ogawa ayenera kukhazikitsidwa
3, kuchokera ku chitoliro chachikulu cha madzi m'madera okhalamo kuyambira pachiyambi cha chitoliro cha nthambi kapena chiyambi cha chitoliro cha banja
4. Chitoliro cham'nyumba, mita ya madzi ndi chokwera cha nthambi iliyonse (pansi pa chokwera, chapamwamba ndi chapansi cha chokwera chokwera ndi chokwera cha mphete chokwera)
5, mphete chitoliro maukonde nthambi chitoliro, kulumikiza chitoliro kudzera nthambi chitoliro maukonde
6, mapaipi operekera madzi m'nyumba m'nyumba, zimbudzi za anthu, etc. kuyambira chiyambi cha chitoliro chogawa madzi, kugawa madzi kunthambi kugawa madzi mu 3 ndi seti yoposa 3.
7, madzi mpope potulukira chitoliro, kudziletsa ulimi wothirira mpope suction mpope
8. Mapaipi olowera m'thanki yamadzi ndikutulutsa ndi mapaipi otulutsa
9, zipangizo (monga chotenthetsera, kuzirala nsanja, etc.) madzi kudzaza chitoliro
10, zida zaukhondo (monga zazikulu, zokodzera, beseni lochapira, shawa, etc.)
11, zida zina, monga valavu yotulutsa yokha, valavu yopumira, chowongolera nyundo yamadzi, choyezera kuthamanga, sprinkler bolt, valavu yochepetsera kupanikizika ndi chipangizo choletsa kubweza chisanachitike ndi pambuyo pake.
12. Valavu yotulutsa madzi iyenera kukhazikitsidwa kumunsi kwa maukonde operekera madzi
(zitatu) fufuzani ma valve
Ma valve owunikira ayenera kusankhidwa molingana ndi malo oyika, kuthamanga kwa madzi patsogolo pa valve, zofunikira zosindikizira pambuyo potseka ndi kukula kwa nyundo yamadzi yomwe inayambika potseka, ndi zina zotero.
1. Pamene kuthamanga kwa madzi kusanayambe valavu ndi yaying'ono, mtundu wa swing, mtundu wa mpira ndi valve yoyang'ana shuttle iyenera kusankhidwa.
2. Pamene ntchito yopuma mpweya itatha kutseka ikufunika kwambiri, valve yowunikira yokhala ndi kasupe yotseka iyenera kusankhidwa
3. Pamene nyundo yamadzi ikufunika kuti ifooke ndi kutsekedwa, ndi bwino kusankha valavu yotseka yotseketsa kapena valavu yotsekera pang'onopang'ono yokhala ndi chipangizo chonyowa.
4, fufuzani kuphulika kwa valve kapena spool, iyenera kutseka pansi pa mphamvu yokoka kapena masika
(4) Ma valve a chekeni adzayikidwa mu mapaipi operekera madzi
Mu chitoliro; Pa chitoliro cholowera cha chotenthetsera chamadzi chotsekedwa kapena zida zamadzi; Pa mpope potulutsira madzi; Pa potuluka chitoliro gawo la thanki madzi, madzi nsanja ndi upland dziwe la chitoliro chomwecho.
Zindikirani: ma valve owunika safunikira pazigawo za mapaipi okhala ndi zoletsa kubweza kwa chitoliro.
(5) Malo a chipangizo chopopera paipi yamadzi
1, kugwiritsa ntchito kwapakatikati kwa netiweki yamadzi, kutha kwa netiweki ya chitoliro ndi malo apamwamba ayenera kukhazikitsidwa ndi valavu yotulutsa yokha
2. Vavu yozimitsira yokha kapena valavu yamanja yakhazikitsidwa pachimake cha gawo la chitoliro ndi kuwunjika kowonekera kwa mpweya mu netiweki yamadzi.
3, chipangizo chamadzi chopumira mpweya, mukamagwiritsa ntchito tanki yamadzi yodzaza mpweya, kufananitsa kwa netiweki yogawa madzi kuyenera kukhala ndi valavu yotulutsa yokha.
Muyezo uwu umagwira ntchito pagalimoto yamagalimoto, kuwongolera kwamagetsi, valavu yachipata chimodzi, valavu yapadziko lonse lapansi, valavu yobowola, diaphragm valavu, valavu ya mpira, valavu ya pulagi, valavu ya butterfly ndi zida zina zamagetsi zamagetsi (zomwe zimatchedwa zida zamagetsi). Mphepete mwa nyanjayi ili ndi zinthu zomwe, malinga ndi muyezo wapadziko lonse lapansi, zimapanga zomwe zili mulingo wapadziko lonse lapansi. Zosindikizidwa zomwe zawonetsedwa ndizovomerezeka panthawi yomwe mulingowu umasindikizidwa. Miyezo yonse imawunikidwanso ndipo omwe akugwiritsa ntchito muyezowu akuyenera kufufuza mwayi wogwiritsa ntchito mitundu ya *** yamiyezo iyi.
