Namhlanjesi siragela phambili nokukhuluma ngeenqabo zokufaka amavalvu:
I-Tabou 12
Iinqophiso namamodeli wevalvu efakiweko awahlangabezani neemfuneko zokuklama.
Ukwenza isibonelo, umfutho wevalvu ungaphasi komfutho wokuhlolwa kwesistimu; ivalvu yesango lephayiphu yamagatja wamanzi wokuphakela lokha ububanzi bephayiphu bungaphasi nofana bulingana nama-50mm; i-dry kanye ne-risers yokufuthumeza amanzi atjhisako; begodu iphayiphu yokudonsa yepompo yomlilo yamukelaivalvu yevivane.
Imiphumela: ithinta ukuvulwa nokuvalwa okujayelekileko kwevalvu begodu ilungise ukujamelana, ukugandeleleka neminye imisebenzi. Ngitjho nanyana kubangele ukusebenza kwesistimu, ukulimala kwevalvu kukateleleka bona kulungiswe.
Iinlinganiso: Yazi ububanzi bokusetjenziswa kwamavalvu ahlukahlukeneko, begodu ukhethe ukucaciswa namamodeli wamavalvu ngokuya ngeemfuneko zokuklama. Umfutho wevalvu uzakuhlangabezana neemfuneko zomfutho wokuhlolwa kwesistimu. Ngokuya ngekhodi yokwakha: ivalvu yokumisa izakusetjenziswa lokha ububanzi bephayiphu bungaphasi nofana bulingana nama-50mm; ivalvu yesango izakusetjenziswa lokha ububanzi bephayiphu bungaphezu kwama-50mm. Ukufuthumala kwamanzi atjhisako omileko, ivalvu yokulawula eqondileko kufanele isetjenziswe ivalvu yesango, iphayiphu yokudosa ipompo yamanzi womlilo akukafaneli isetjenziswe ivalvu yevithamini.

Iinsetjenziswa ezikulu, imitjhini nemikhiqizo esetjenziswa ekwakhiweni ayinawo amadokhumenti wokuhlola ikhwalithi yezobuchwepheshe nofana isitifiketi somkhiqizo esihlangabezana namazinga wamanje wesitjhaba nofana weNgqongqotjhe.
Imiphumela: ikhwalithi yephrojekthi engakafaneli, iingozi ezingaba khona, angeze yalethwa ngesikhathi, kufanele isetjenzwe kabutjha begodu ilungiswe; okurholela ekulibazisekeni kokwakha nokwanda kwabasebenzi nezinto ezifakwako.
Iinlinganiso: Iinsetjenziswa ezikulu, imitjhini nemikhiqizo esetjenziswa emaphrojekthini wokuphakelwa kwamanzi nokufuthumeza kufanele ibe namadokhumende wokuhlola ikhwalithi yezobuchwepheshe nofana isitifiketi somkhiqizo esihambisana namazinga wamanje akhutjhwe mbuso nofana uMnyango; okwanje, ibizo lomkhiqizo, imodeli, ukucaciswa, ikhodi yekhwalithi yezwe, ilanga lokulethwa, ibizo lomkhiqizi nendawo, isitifiketi sokuhlola nofana ikhodi kuzokutjengiswa.

Ivalvu iphendukile
Imiphumela: i-velve yokuhlola, i-throttle valve, i-pressure reducing valve, i-check valve namanye ama-valve anendlela, nangabe ifakwe iphendukile, i-throttle valve izokuthinta umphumela wesevisi nepilo; ivalvu yokunciphisa umfutho ayisebenzi, ivalvu yokuhlola ingabangela ingozi.
Iinlinganiso: ivalvu jikelele, enetshwayo lokuqondisa emzimbeni wevalvu; nangabe akunjalo, kufanele ikhonjwe kuhle ngokuya ngomthetho wokusebenza kwevalvu. Umgodi wevalvu we-stop valve awulinganiko, uketshezi kufanele luvumele bona ludlule emlonyeni wevalvu ukusuka phasi ukuya phezulu, ukwenzela bona ukujamelana kwe-fluid kube mncani (okunqunywa bujamo), ukuvula umsebenzi (ngebanga lokugandeleleka okuphakathi phezulu), ukuvala okuphakathi akugandeleli ukupakisha, ukutlhogonyelwa kulula. Kungakho i-valve yokujama ingakghoni ukulungiswa.

Ivalvu ayenzi iindlela zokuvikela umtjhiso nokupholisa
Iindlela: amanye amavalvu kufanele abe neensetjenziswa zangaphandle zokuvikela, lokhu kukuvikela ukutjhisa nokuvikela emakhazeni. Iphayiphi yomtjhiso wokuvikela ukutjhisa kesinye isikhathi ifakwa esendlalweni sokuvikela. Ngimuphi umhlobo wevalvu okufanele uvikelwe namkha ubanda, ngokuya ngeemfuneko zokukhiqiza. Ngokomthetho, lapho umkhathi osevalvu wehlisa khulu amazinga womtjhiso, kuzokuthinta ukusebenza kuhle kokukhiqiza nofana kuqandise ivalvu, itlhoga ukuvikelwa, ngitjho nokulandelela umtjhiso; lapho ivalvu ivezwe khona, ingakhiqizi namkha ibangela isithwathwa nezinye izinto ezimbi, kuyatlhogeka bona igcine ibanda. Iinsetjenziswa zokuvikela ukutjhisa zifaka hlangana i-asbestos, ikotoni ye-slag, i-glass wool, i-perlite, ihlabathi ye-diatom, i-vermiculite; izinto zokuzivikela emakhazeni zifaka hlangana ikhokho, i-perlite, i-foam, iplastiki, njll.

Ivalvu yokukhipha amanzi ayifakwa ngokudlula
Iinlinganiso: amanye amavalvu, ngaphezu kweensetjenziswa zokuvikela ezitlhogekako, kodwana anendlela yokudlula kanye nethulusi. Indlela yokudlula ifakwe ukusiza ukugcinwa kwesithiyo samanzi. Amanye amavalvu, nawo afakwe i-bypass. Ukuthi kufakwe i-bypass kuya ngobujamo bevalvu, ukuqakatheka kanye neemfuneko zokukhiqiza.

I-filler beyingakatjhugululwa qobe
Iinlinganiso: ivalvu ye-inventory, enye i-filler ayikalungi, eminye ayivumelani nokusetjenziswa kwemidiya, okutlhoga ukubuyiselwa kwe-filler.
Ivalvu iqalene neenkulungwana zeenhlobo zemidiya ehlukileko, begodu incwadi yokugcwalisa ihlala izaliswa ngemirabhu yepuleti ejayelekileko, kodwana lokha nayisetjenziswako, ukupakisha kufanele kuvumelane nemidiya.
Lokha nawutjhugulula isigcwalisi, sicindezele ngokujikeleza. I-lap joint ngayinye ingamadigri ama-45, begodu indandatho nendandatho yokuhlangana ngamadigri ali-180. Ukuphakama kokupakisha kufanele kucabangele ikamelo lokuragela phambili nokucindezela isivalo, begodu njenganje, ingcenye engezansi yesivalo kufanele ibe nokujula okufaneleko, okungaba yi-10-20% yokujula okupheleleko kwegumbi lokupakisha.
Ngaphandle kwalokho, i-Tianjin Tanggu Water Seal Valve Co., Ltd. yi-elastic seat valve esekela amabhizinisi, imikhiqizo yi-elastic seat wafer butterfly valve,i-lug butterfly valve,ifletjhi ephindwe kabili, ifletjhi ephindwe kabiliivalvu yevithamini engakajayeleki, ivalvu yokulinganisa,i-wafer dual plate check valve, Y-Strainer njalonjalo. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyazikhakhazisa ngokunikela ngemikhiqizo esezingeni eliphezulu ehlangabezana namazinga aphezulu webubulo. Ngamavalvu wethu ahlukahlukeneko, ungasithemba bona sizokunikela ngesisombululo esihle khulu sehlelo lakho lamanzi. Sithinta namhlanjesi ukufunda kabanzi ngemikhiqizo yethu nokuthi singakusiza njani.
