Forged National Standard Globe Valve

Ochwepheshe abaningi bonjiniyela abathenga ama-valve amapayipi bavame ukukhathazeka ngokuhlangabezana nezinkinga. Bangase bahlangane nemikhiqizo enobukhulu obungalungile obungakwazi ukufakwa, noma ama-valve aphuka ngokushesha ngemva kokusetshenziswa. Ikakhulukazi ezimweni ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu, noma yiziphi izinkinga zingase zibe nzima kakhulu. Ivalvu yethu yembulunga esezingeni likaZwelonke eyakhiwe yakhelwe ngokukhethekile izimo ezinzima kangaka.

Izinzuzo eziyinhloko

Umzimba we-valve wenziwe nge-A105N yensimbi eyenziwe ngekhabhoni engumgunyathi, ehlukile kunemizimba ejwayelekile yamavalvu enziwe. Inqubo yokubumba iqeda amaphutha angabonakali njengama-pores kanye nezimbobo zesihlabathi ensimbi, okwenza isakhiwo siminyene futhi sinikeze ukwanda okuqondile komthamo wokuthwala ingcindezi. Le valve yembulunga yembulunga ejwayelekile efojiwe ingamelana nezinga lokushisa eliphakeme elingu-425°C futhi ingaphakathi kwengcindezi ye-PN16. Ngisho nokuguquguquka kwengcindezi phakathi kwamapayipi esitimu kungaphathwa ngendlela enokwethenjelwa. Indawo yokuvala isebenzisa i-Samtler cobalt-based hard alloy welding, engagugi futhi imelana nokuklwebheka. Ingakwazi ukumelana namashumi ezinkulungwane zokuvuleka nokuvalwa ngaphandle kokuvuza. Isiqu se-valve senziwe ukwelashwa kokucisha kanye ne-nitriding, okuyenza imelane nokugqwala. Ngisho nemithombo yezindaba eyonakalisa kancane, ayesabi. Ngaphezu kwalokho, ukupakisha kungashintshwa ku-inthanethi ngaphandle kokumisa nokudiliza yonke i-valve, okwenza ukulungiswa kube lula kakhulu.

Imininingwane yobuchwepheshe

Lena i-J41H-16C DN25 PN16 abantu abavame ukubuza ngayo. Ububanzi obujwayelekile bungama-25mm, ingcindezi yokulinganisa ingu-1.6MPa, i-valve body material i-A105N, indlela yokuxhuma iwukuxhuma kwe-flange okujwayelekile, futhi ukwakheka nokukhiqiza kuhambisana ngokugcwele nezinga lezwe le-GB12235. Ubude besakhiwo namazinga we-flange wonke ahambisana ne-HG/T20592. Ukuhlolwa nokuhlolwa kuphinde kwaphumelela izinga le-JB/T9092. Bonke ubukhulu bulawulwa ngokunembile, futhi uma butholakele, bungakwazi ukuxhunywa ngokuqondile epayipini ngaphandle kokulungiswa. Ngaphezu kwalokho, i-valve yethu yeglobu ye-globe ejwayelekile ingashintshwa ibe izinto ezahlukahlukene ngokuya ngezimo zakho zokusebenza. Insimbi engagqwali ne-alloy steel ingasetshenziswa. Ingakwazi ukuhlangabezana nezidingo zemidiya ehlukene.

Izinzuzo zokuncintisana

Uma kuqhathaniswa nezimbangi, izimboni eziningi ezincane zisebenzisa imizimba yama-valve ukusindisa izindleko. Zingase zibukeke zifana, kodwa kunemigodi yesihlabathi ngaphakathi, futhi ziyavuza ngemva kokuzisebenzisa unyaka owodwa noma emibili. Ezimweni ezinengcindezi ephezulu, bavame ukuba nezingozi zokuphepha. Inqubo yethu yokubumba, nakuba ibiza kakhulu, inamandla omzimba we-valve ephakeme izikhathi ezingu-1.5 kunaleyo yokuphonsa. Ubude bempilo bungaphindwa kabili. Ivalvu yethu yembulunga esezingeni likaZwelonke eqanjiwe ingamelana nokuguguleka kwemithombo yezindaba equkethe izinhlayiya futhi ngeke iphuke kalula. Ngokuhamba kwesikhathi, kubiza kakhulu futhi akudingi ukushintshwa kwama-valve njalo, okugcina isikhathi sokukhiqiza.

Kungani ukhethe thina?

Siyi-Huadu Valves, amashumi eminyaka sisebenza ekukhiqizeni ama-valve. Yonke imikhiqizo yethu ikhiqizwa efekthri yethu. Kusukela ekungeneni kwezinto zokusetshenziswa kuze kube sekuqedweni kwemikhiqizo eqediwe, zonke izinyathelo ziyahlolwa. Asilokothi sisebenzise imikhiqizo esezingeni eliphansi ukukhohlisa noma ubani. Ngaphezu kwalokho, sinenani elikhulu lemikhiqizo esitokweni. Lokhu kucaciswa kwe-DN25 kungathunyelwa ngqo kusuka endaweni yokugcina izinto ngaphandle kokuthi ulinde umjikelezo omude wokukhiqiza. Siphinde sinikeze ngezinsizakalo zokwenza ngokwezifiso. Ama-flange akhethekile nezinto ezikhethekile zingakhiqizwa. Sibambe iqhaza kumaphrojekthi amaningi amakhulu futhi sinolwazi oluningi.
