Ivalvu mtjhini ovame khulu emabhizinisini wamakhemikhali. Kubonakala kulula ukufaka amavalvu, kodwana nangabe awulandeli ithekhnoloji efaneleko, kuzokubanga iingozi zokuphepha. Namhlanjesi ngithanda ukwabelana nawe ngesipiliyoni sokufakwa kwevalvu.
1. Ukuhlolwa kwamanzi emazingeni womtjhiso angakalungi ngesikhathi sokwakha ebusika.
Imiphumela: ngombana itjhubhu iyaqanda msinyana ngesikhathi sokuhlolwa kwe-hydraulic, itjhubhu iyaqanda.
Iindlela: linga ukwenza ukuhlolwa kwamanzi ngaphambi kokufaka isicelo ebusika, begodu ngemva kokuhlolwa kokugandeleleka ukuvuthela amanzi, khulukhulu amanzi asevalvu kufanele asuswe enetheni, ngaphandle kwalokho ivalvu izokurusela, iqhwa elinzima. Iphrojekthi kufanele yenziwe ebusika, ngaphasi kwezinga lokutjhisa elihle langaphakathi, begodu amanzi kufanele aphephetheke ahlanzeke ngemva kokuhlolwa komfutho.
2, Ukuhlolwa kwamandla we-hydraulic wesistimu yamapayipi nokuhlolwa kokuqina, ukuhlolwa kokuvuza akwanele.
Imiphumela: ukuvuza kwenzeka ngemva kokusebenza, okuthinta ukusetjenziswa okujayelekileko.
Iindlela: Lokha ihlelo lamaphayiphi nalihlolwa ngokuya kweemfuneko zokuklama kanye neenqophiso zokwakha, ngaphezu kokurekhoda inani lomfutho nofana ukutjhuguluka kwezinga lamanzi ngesikhathi esibekiweko, khulukhulu hlola ngokutjheja bona ingabe kunomraro wokuvuza.
3, ipuleti yefletjhi yevalvu ye-Butterfly enepuleti yefletjhi yevalvu ejayelekileko.
Imiphumela: ubukhulu bepleyidi ye-flange ye-valve ye-velve kanye ne-valve flange ejayelekileko ubukhulu buhlukile, ububanzi bangaphakathi be-flange buncani, begodu idiski ye-valve ye-butterfly yikulu, okurholela ekutheni ingavuleki namkha ivuleke khulu begodu yenza bona i-valve ilimale.
Iinlinganiso: ipuleti ye-flange kufanele isetjenziswe ngokuya ngobukhulu be-butterfly valve flange.
4. Indlela yokufaka ivalvu ayikalungi.
Ukwenza isibonelo: ukugeleza kwamanzi (umtjhiso) we-valve yokuhlola iphambene nephawu, isiqu se-valve sifakwe phasi, i-valve yokuhlola efakwe ngokuvundlileko ukuthatha ukufakwa okujameleko, i-valve yesango le-stem ekhuphukako nofanaivalvu yevivane yokuvala okuthambilekoisibambo asivulekile, vala isikhala, njll.
Imiphumela: ukubhalelwa kwevalvu, ukutlhogonyelwa kweswitjhi kubudisi, begodu ishafu yevalvu eqale phasi kanengi kubangela ukuvuza kwamanzi.
Iinlinganiso: ngokuqinileko ngokuya kwemiyalo yokufaka ivalvu yokufaka, vula ivalvu yesango le-rod ukugcina ukuphakama kokuvuleka kwesiqu sevalvu, ivalvu ye-butterfly icabangela ngokuzeleko isikhala sokujikeleza kwesibambo, zoke iinhlobo zesiqu sevalvu angeze zaba ngaphasi kwendawo evundlileko, ingasaphathwa yehla.
5. Iinqophiso namamodeli wevalvu efakiweko awahlangabezani neemfuneko zokuklama.
Ukwenza isibonelo, umfutho wevalvu ungaphasi komfutho wokuhlolwa kwesistimu; ipayipi legatja lamanzi wokuphakela lamukela iivalvu yesangolokha ububanzi bephayiphu bungaphasi nofana bulingana nama-50mm; iphayiphu yokudonsa yepompo yomlilo yamukela ivalvu yevithamini.
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.
6. Ukuphenduka kwevalvu
Imiphumela:ivalvu yokuhlola, ivalvu yokwehlisa umfutho namanye amavalvu anendlela, nangabe ifakwe iphendukile, ivalvu ye-throttle izokuthinta umphumela wesevisi nepilo; ivalvu yokwehlisa umfutho ayisebenzi, ivalvu yokuhlola ingabangela ingozi.
Iinlinganiso: ivalvu jikelele, enetshwayo lokuqondisa emzimbeni wevalvu; nangabe akunjalo, kufanele ikhonjwe kuhle ngokuya ngomthetho wokusebenza kwevalvu. Ivalvu yesango akukafaneli iphendulwe (okutjho bona, isondo lesandla libe phasi), ngaphandle kwalokho kuzokwenza bona umtjhini ohlala esikhaleni se-boncover isikhathi eside, kube lula ukubola isiqu sevalvu, begodu kube budisi khulu ukufaka isigcwalisi. Amavalvu wesango lesiqu esikhuphukako awafakwa ngaphasi kwehlabathi, ngaphandle kwalokho ayabola isiqu sevalvu esivulekileko ngebanga lomswakama.Ivalvu yokuhlola yokujinga, ukufakwa ukuqinisekisa bona izinga leshafti lephini, ukwenzela bona liguquguquke.
