Ama-valve ebholaziyizakhi ezisemqoka ezinhlelweni zokulawula uketshezi, enikeza ukusebenza okuthembekile emikhakheni ehlukahlukene. Ukukhetha phakathi kwe-zethusi nensimbi yensimbi yensimbi, noma kunjalo, kungaba ngumsebenzi oyinselele. Indwangu ngayinye iletha izakhiwo ezihlukile nezinzuzo etafuleni, okwenza kubalulekile ukuqonda umehluko wazo ngokuningiliziwe. Kulesi siqondisi esiphelele, sizohlaziya zombili izinketho ukukusiza wenze isinqumo esihle kakhulu sohlelo lwakho lokusebenza.
1. Ukwakheka kwezinto ezibonakalayo nezakhiwo
I-Brass Ball valves
I-Brass yi-alloy yethusi ne-zinc, ngamanani alandela ezinye izinsimbi ezinjengokuholela ukuze athuthukise amakhono. Izici zalo ezibalulekile zifaka:
• Ukulwa:Kubunjwe kalula futhi kufakwe imishini, okwenza ama-valves ethusi abiza kakhulu ukukhiqiza.
• Ukumelana nokugqwala:Ukumelana nokugqwala nokugqwala ezindaweni ezingathathi hlangothi noma ezilimazayo.
• Ukuqhutshwa kwe-Thermal:Ukusebenza okuhle kakhulu kokushisa, okulungele izinhlelo ezinezidingo zokushisa eziphakathi.
Ama-valve ensimbi engagqwali
Insimbi engenasici i-alloy eyakhiwe nge-iron, chromium, kanye ne-nickel. Izakhiwo zayo ezihlukile zifaka:
• Amandla aphezulu:Ekwazi ukubekezelela ukucindezela okukhulu kanye nokucindezelwa kwemishini.
• Ukuphikiswa okuhlukile kokugqwala:I-Chromium yakha ungqimba olungenangqondo ngaphezulu, ukuvikela ngokumelene ne-oxidation kanye nokuhlaselwa kwamakhemikhali.
• Ukubekezelela izinga lokushisa:Isebenza ngempumelelo kulo lonke uhla lokushisa olubanzi.
2. Ukumelana nokuqina: ukuqhathanisa okuningiliziwe
Ukuphikiswa kokugqwala kungenye yezinto eziyinhloko okufanele ucabangele lapho ukhetha impahla ye-valve yebhola.
• Ithusi:Ithusi liphikisana nokugqwala ezindaweni ezihlanzekile namakhemikhali amancane. Kodwa-ke, itholakala ekuthobeni, inqubo lapho iZinc ikhipha khona ngaphansi kokuvezwa isikhathi eside kwezinto ezi-acidic noma ze-alkali, zenze buthaka okubonakalayo. I-Brass nayo ayinconyelwa ukusetshenziswa ngamanzi olwandle noma ama-chlorine-rich system.
• Insimbi engagqwali:Insimbi engenasici, ikakhulukazi amamaki afana ne-304 no-316, ihlinzeka ngokumelana kahle nokugqwala, ngisho nasezindaweni ezinolaka. Thayipha insimbi engama-316 engagqwali, ukucebiswa nge-molybderum, inikeza ukuvikeleka okuthuthukile ngokumelene ne-chloride pitting futhi ilungele izinhlelo zasolwandle.
I-valve yensimbi engenasici
3. Amandla, ukuqina, kanye nokuphila isikhathi eside
Amandla nokuqina kunquma amandla we-valve okwenza ngaphansi kwengcindezi.
• I-Brass Ball valves:Ama-valves we-Brass aqinile anele ngokwanele izinhlelo zokusebenza zansuku zonke kodwa angahle aze akhubazeke ngaphansi kwengcindezi ephezulu noma izimo zokushisa eziphakeme. Ngenkathi ihlala isikhathi eside ezindaweni ezingezinhle, isikhathi sazo sokuphila sincipha kuzilungiselelo ezinolaka.
• Ama-valves wensimbi engenasici:Ama-valves ensimbi engagqwali axclul ngokuqina, ukugcina ubuqotho ngaphansi kwengcindezi enkulu, izinga lokushisa kanye nengcindezi yemishini. Lokhu kubenza balungele izinhlelo zokusebenza ezifunwa kwezimboni nezezinto eziphakeme, lapho ukuthembeka kubalulekile.
4. Ukushisa nokuphendula kwengcindezi
Izimo zokusebenza zohlelo lwakho zidlala indima ebaluleke kakhulu ekukhetheni kwezinto ezibonakalayo.
• Ithusi:Ama-valves webhola lethusi asebenza ngempumelelo ezinhlelweni ezinamazinga okushisa afinyelela ku-200 ° F (93 ° C) kanye nengcindezi ezungeze ama-300 psi. Zilungele kahle izinhlelo zezimboni zokuhlala nezikhangayo.
• Insimbi engagqwali:Ama-valves ensimbi engagqwali angaphatha izimo ezimbi kakhulu, ngokubekezelelana okushisa okudlula 400 ° C (204 ° C) nezingcindezi ezidlula 1 000 psi. Zenzelwe izindawo ezifunwayo ezifana nezinhlelo ze-Steam, ukucubungula kwamakhemikhali, kanye namapayipi aphezulu.
Ukucatshangelwa kwe-5.URirolal and Safety
• Ithusi:Kuqukethe amanani okuhola okuhola, angenzakale amanzi aphathekayo uma engahlanganisi kahle noma ahlanganiswe. Izinketho ze-Heath-Free Brass ziyatholakala ukuze zithobele amazinga okuphepha okuphuza amanzi, njengaleyo echazwe e-US ephephile yokuphuza amanzi.
• Insimbi engagqwali:Insimbi engenabungozi futhi engeyona eye-anobuthi, yensimbi engenabuci, yensimbi ilindelwe ukufaka izicelo ezibandakanya amanzi aphathekayo, amakhamishini kanye nokukhiqizwa kokudla. Ngokwengeziwe, kuphinde kwatholakala, okwenza kube ukukhetha okunobungane kwemvelo.
Izidingo ze-6.Maintweint
• Ithusi:Ama-valves ethusi adinga ukulungiswa okuncane ezindaweni ezithambile. Kodwa-ke, ezimweni ezilonakalisayo, ukuhlolwa okuvamisile kungadingeka ukuthola izimpawu zokuqala zokuzithoba.
• Insimbi engagqwali:Ama-valves ensimbi angenasici alungiswa kancane futhi agcine ukubukeka kwawo nokusebenza kwawo ngokuhamba kwesikhathi, ngisho nasezimweni ezinzima. Ukuhlanza okujwayelekile kungadingeka ezindaweni ezingcolisayo zokugcina ukusebenza kahle.
7. Izici okufanele zicatshangelwe lapho ukhetha
Ukwenza ukukhetha okulungile, hlola lezi zinto:
• Imvelo Yokusebenza:Hlola izinga lokushisa, ingcindezi, kanye nokuchayeka ezintweni ezilimazayo.
• Izingqinamba zesabelomali:Ibhalansi izindleko eziphambili ngokulondolozwa kwesikhathi eside.
• Izidingo zesicelo:Qondanisa izakhiwo ezibonakalayo ezifunweni ezithile zohlelo.
• Ukulandela umthetho wokulawula:Qinisekisa ukuhambisana namazinga wezimboni ukuze uvikeleke ekuphepheni nasekusebenzeni.
Ukugcina
Ukukhetha i-Valve Valve Material-yethusi efanele noma insimbi engenasici-idinga ukuhlaziya ngokucophelela kwezidingo zohlelo lwakho lokusebenza.I-Brass Ball valvesNikeza isixazululo esisebenza ngempumelelo yezimo ezilinganiselayo, ezedlula zonke izilungiselelo zokuhlala kanye nezinhloso ezijwayelekile.Ama-valve ensimbi engagqwali, ngakolunye uhlangothi, ukukhethwa kokuzikhethela kwezindawo ezifunwayo lapho amandla, ukumelana nokugqwala, nokuphila isikhathi eside kubaluleke kakhulu.
Ngokuqonda izakhiwo eziyingqayizivele nezinzuzo zento ngayinye, ungenza isinqumo esinolwazi esiqinisekisa ukusebenza kahle, ukuphepha, kanye nokusebenza kwezindleko zephrojekthi yakho. Noma ngabe ngohlelo lwamapayipi endlu noma ipayipi lezezimboni, izinto ezifanele zebhola lezinto ze-valve zingenza wonke umehluko.
