Yenzani i-valve?

I-valve iwukunamathiselwe kwepayipi esetshenziselwa ukuvula nokuvala amapayipi, ukulawula isiqondiso sokugeleza, ukulawula nokulawula imingcele (izinga lokushisa, ingcindezi kanye nezinga lokugeleza) kwendawo edluliswayo. Ngokusho komsebenzi wayo, ingahlukaniswa ngama-valve avaliwe,hlola ama-valve, ama-valve okulawula, njll.

Amavalvu ayizingxenye zokulawula ezinhlelweni zokuthutha uketshezi, ezinemisebenzi yokuvala, ukulawula, ukuphambukisa, ukuvimbela ukugeleza okubuyela emuva, ukuqiniswa kwengcindezi, ukuphambukisa noma ukukhululeka kwengcindezi yokuchichima. Amavalvu ezinhlelo zokulawula uketshezi asukela kumavalvu alula ukuvala kuya kumavalvu ayinkimbinkimbi kakhulu asetshenziswa ezinhlelweni zokulawula ezizenzakalelayo.

Amavaluvu angasetshenziswa ukulawula ukugeleza kwezinhlobo ezahlukene zoketshezi olunjengomoya, amanzi, isitimu, imidiya eyonakalisayo ehlukahlukene, ama-slurries, amafutha, izinsimbi eziwuketshezi kanye nemidiya ekhipha imisebe. Ngokusho kwempahla, ama-valve nawo ahlukaniswe abeama-valve ensimbi, amavalvu ensimbi enziwe ngensimbi, amavalvu ensimbi engagqwali (201, 304, 316, njll.), amavalvu ensimbi e-chrome-molybdenum, i-chromium-molybdenum vanadium steel valves, amavalvu ensimbi e-duplex, amavalvu epulasitiki, amavalvu enziwe ngokwezifiso angajwayelekile, njll.

Hlela

Ngokusebenza nokusetshenziswa

(1) Ivalvu yokuvala shaqa

Lolu hlobo lwe-valve lusetshenziselwa ukuvula nokuvala. Ifakwe unomphela endaweni yokungena nokuphumayo yemithombo ebandayo neyokushisa, indawo yokungena nokuphuma kwezinto zokusebenza, kanye nomugqa wegatsha wamapayipi (okuhlanganisa nezikhuphukeli), futhi ingasetshenziswa njengevalufu yokukhipha amanzi kanye nevalvu yokukhulula umoya. Ama-valve ajwayelekile okuvala ahlanganisaama-valve esango, ama-valve embulunga, ama-valve ebhola namavalve uvemvane.

Ama-valve esangoingahlukaniswa ibe induku evulekile kanye nenduku emnyama, inqama eyodwa nenqama ephindwe kabili, inqama ye-wedge nenqama ehambisanayo, njll. Ukuqina kwe-valve yesango akukuhle, futhi kunzima ukuvula i-valve yesango elikhulu; Ubukhulu bomzimba we-valve buncane ngokuhambisana nokugeleza kwamanzi, ukumelana nokugeleza kuncane, futhi ububanzi obujwayelekile be-valve yesango bukhulu.

Ngokusho kokuqondisa kokugeleza kwe-medium, i-valve yembulunga ihlukaniswe yaba izinhlobo ezintathu: uhlobo oluqondile, uhlobo lwe-engeli yesokudla kanye nohlobo lokugeleza okuqondile, futhi kukhona izinduku ezivulekile nezinduku ezimnyama. Ukuqina kokuvala kwe-valve yembulunga kungcono kunaleyo ye-valve yesango, umzimba we-valve mude, ukumelana nokugeleza kukhulu, kanye nobukhulu obujwayelekile be-DN200.

I-spool ye-valve yebhola iyibhola elivulekile. Isiqu se-valve esebenza ngepuleti senza ibhola livuleke lapho libheke eksisi yepayipi, futhi livaleka ngokugcwele lapho liphenduka u-90°. I-valve yebhola inokusebenza okuthile kokulungiswa futhi ivala ngokuqinile.

I-spool ye-uvemvane valveiyidiski eyindilinga ezungeza ku-shaft eqondile ye-axis yepayipi eqondile. Lapho indiza ye-valve plate ihambisana ne-axis yepayipi, ivuliwe ngokugcwele; Lapho indiza yenqama i-perpendicular ku-axis yepayipi, ivalwe ngokugcwele. Ubude bomzimba we-butterfly valve buncane, ukumelana nokugeleza kuncane, futhi intengo iphakeme kunaleyo yama-valve esango nama-valve embulunga.

(2) Hlola i-valve

Lolu hlobo lwevalvu lusetshenziselwa ukuvimbela ukugeleza emuva kwendawo ephakathi nendawo, futhi lisebenzisa amandla e-kinetic oketshezi ukuze lizivule futhi livale ngokuzenzakalelayo lapho ligeleza libheke kolunye uhlangothi. Ukuma lapho kuphuma khona iphampu, lapho kuphuma khona isicupho, nakwezinye izindawo lapho ukugeleza koketshezi okubuyela emuva kungavunyelwe. Kunezinhlobo ezintathu zama-valve okuhlola: uhlobo lokuvula olujikelezayo, uhlobo lokuphakamisa kanye nohlobo lwe-clamp. Endabeni yama-valve okuhlola ama-swing, uketshezi lungageleza kuphela lusuka kwesobunxele luye kwesokudla futhi luvale ngokuzenzakalelayo lapho lugeleza lubheke kolunye uhlangothi. Ukuze uthole ama-valve okuhlola okuphakamisa, i-spool iphakamisa ukuze yenze indlela njengoba uketshezi lugeleza ukusuka kwesokunxele ukuya kwesokudla, futhi i-spool iyavalwa uma icindezelwa esihlalweni lapho ukugeleza kubuyiselwa emuva. Kuvalvu yokuhlola i-clamp-on, lapho uketshezi lugeleza lusuka kwesobunxele luye kwesokudla, i-valve core iyavulwa ukuze yakhe indlela, futhi i-valve core icindezelwa esihlalweni se-valve futhi ivalwe lapho ukugeleza okuhlehlayo kubuyiselwa emuva.

(3) Ukulawulaama-valve

Umehluko wengcindezi phakathi kwengaphambili nangemuva kwe-valve uqinisekile, futhi lapho ukuvulwa kwe-valve evamile kushintsha ebangeni elikhulu, izinga lokugeleza lishintsha kancane, futhi lapho lifinyelela ekuvuleni okuthile, izinga lokugeleza lishintsha kakhulu, okungukuthi. , ukusebenza kokulungisa kubi. I-valve yokulawula ingashintsha i-spool stroke ukuze iguqule ukumelana kwe-valve ngokuya ngesiqondiso nosayizi wesignali, ukuze kuzuzwe injongo yokulawula i-valve yokugeleza. Ama-valve okulawula ahlukaniswe abe ama-valve okulawula ama-manual kanye nama-valve okulawula okuzenzakalelayo, futhi kunezinhlobo eziningi zama-valve okulawula ngesandla noma othomathikhi, futhi ukusebenza kwawo kokulungiswa nakho kuhlukile. Ama-valve okulawula okuzenzakalelayo ahlanganisa ama-valve okulawula ukugeleza azisebenza wona kanye nama-valve okulawula ukuhluka okuzisebenza ngokwawo.

(4) Vacuum

I-vacuum ihlanganisa ama-vacuum ball valve, ama-vacuum baffle valves, ama-vacuum vacuum valves, ama-vacuum vacuum valves, njll. Umsebenzi wayo usesistimu ye-vacuum, isici sesistimu ye-vacuum esetshenziselwa ukushintsha indlela yokuhamba komoya, ukulungisa ivolumu yokugeleza komoya, inqanyuliwe. noma ukuxhuma ipayipi kubizwa ngokuthi i-vacuum valve.

(5) Izigaba ezinenhloso ekhethekile

Izigaba zenhloso ezikhethekile zifaka ama-valve ezingulube, ama-vent valves, ama-blowdown valves, ama-exhaust valves, izihlungi, njll.

I-valve yokukhipha umoya iyingxenye ewusizo ebaluleke kakhulu ohlelweni lwamapayipi, esetshenziswa kakhulu kuma-boilers, ama-air conditioner, uwoyela negesi, ukuphakelwa kwamanzi namapayipi okukhipha amanzi. Ivamise ukufakwa endaweni eyalayo noma endololwaneni ukuze kukhishwe igesi eningi epayipini, kuthuthukiswe ukusebenza kahle kokusetshenziswa kwamapayipi kanye nokunciphisa ukusetshenziswa kwamandla.

Noma iyiphi irabha ehleziuvemvane valve, i-valve yesango, i-Y-stainer, i-valve yokulinganisa,i-valve yokuhlola ipuleti elicwecwe kabiliimibuzo, ungaxhumana nayoI-valve ye-TWSifektri. Futhi ungachofoza kuwebhusayithi yethu ethi https://www.tws-valve.com/ ukuze uthole ulwazi olwengeziwe.
