Ivalvu yeButterfly eSebenzayo ePhakamileyo
✧ Inkcazo
Ivalvu yebhabhathane esebenza kakhulu luhlobo lwevalvu eyenzelwe ukusetyenziswa ngokungxamisekileyo efuna ukuvalwa okuthembekileyo, amandla oxinzelelo oluphezulu, kunye nokuvalwa okuqinileyo. Ezi valve zisetyenziswa kakhulu kumashishini afana neoyile negesi, ukucubungula iikhemikhali, ukuvelisa umbane, kunye nokucoca amanzi, phakathi kwezinye. Zibonakaliswa kubuchule bazo bokubonelela ngolawulo lokuhamba kakuhle kunye nokumelana neemeko zokusebenza ezinzima. Ezinye zeempawu eziphambili zeevalvu zebhabhathane ezisebenzayo ziquka: Ukuvala Ngokuqinileyo: Ezi valve zenzelwe ukunciphisa ukuvuza kunye nokubonelela ngetywina elithembekileyo nakwiindawo ezinoxinzelelo oluphezulu okanye ubushushu obuphezulu. Ulwakhiwo Oluqinileyo: Iivalvu zebhabhathane ezisebenzayo kakhulu zihlala zakhiwa ngezinto ezihlala ixesha elide, njengentsimbi engagqwaliyo okanye ii-alloys zangaphandle, ukumelana ne-corrosive okanye i-abrasive media. Ukusebenza kweTorque ephantsi: Iivalvu ezininzi zebhabhathane ezisebenzayo kakhulu zenzelwe ukusebenza kwe-torque ephantsi, okuvumela ukusebenza ngokufanelekileyo kunye nokunciphisa ukuguguleka kwezinto zevalvu. Uyilo Olukhuselekileyo Emlilweni: Ezinye iivalvu zebhabhathane ezisebenzayo kakhulu zenzelwe ukuhlangabezana nemigangatho ekhuselekileyo emlilweni, zibonelela ngomaleko owongezelelweyo wokhuseleko xa kwenzeka ingozi yomlilo. Amandla Oxinzelelo Oluphezulu: Ezi valve zifanelekile kwizicelo ezifuna amandla okuphatha uxinzelelo oluphezulu. Xa ukhetha ivalvu yebhabhathane esebenza kakhulu, kubalulekile ukuqwalasela izinto ezifana nesicelo esithile, iimeko zokusebenza, ukuhambelana kwezinto, imigangatho yeshishini, kunye nokuqwalaselwa kwendalo. Ubungakanani kunye nokukhetha okufanelekileyo kubalulekile ukuqinisekisa ukuba ivalvu ihlangabezana neemfuno zokusebenza zesicelo esicetywayo.
✧ Iimpawu zeValve yeButterfly eSebenza kakuhle
Iivalvu zeButterfly ezisebenza kakuhle kakhulu zinezihlalo zepolymer compound ezinobomi obungenamda kunye nokumelana okuphezulu kakhulu kweekhemikhali - zimbalwa iikhemikhali ezaziwayo ukuba zichaphazela iipolymers ezisekwe kwi-fluorocarbon, nto leyo eyenza ezi mveliso zibe nomtsalane kwiivalvu zemizi-mveliso. Umgangatho wazo udlula owerabha okanye ezinye iipolymers ze-fluorocarbon ngokubhekiselele kuxinzelelo, ubushushu kunye nokumelana nokuguguleka.
Uyilo lweValve iyonke
Isiqu seHigh Performance Butterfly Valve asikho embindini kwiiplani ezimbini. I-offset yokuqala ivela kumgca ophakathi wevalvu, kwaye i-offset yesibini ivela kumgca ophakathi wepayipi. Oku kubangela ukuba idiski ihlukane ngokupheleleyo nediski kwiidigri ezimbalwa zokusebenza ukusuka kwisihlalo. Jonga umfanekiso ongezantsi:
Uyilo lwesihlalo
Ngokuphathelele isihlalo, njengoko bekutshiwo ngaphambili, ivalvu enerabha ivalwa ngokucinezela kwisingxobo serabha. Uyilo lwesihlalo se-G se-High Performance Butterfly Valve. Umfanekiso ongezantsi uchaza indlela yokuhlala echaphazeleka ngayo kwiimeko ezi-3:
Emva kokuhlanganiswa: xa kuhlanganiswa phantsi koxinzelelo
Xa ihlanganiswe ngaphandle koxinzelelo, isihlalo sisebenza ngepleyiti yebhabhathane. Oku kuvumela ukutywinwa kweqamza ukusuka kwinqanaba le-vacuum ukuya kwinqanaba eliphezulu loxinzelelo lwevalvu.
Uxinzelelo lwe-Axial:
Iprofayili yesihlalo se-G idala isitywino esiqinileyo njengoko ipleyiti ishukuma. Uyilo lokufakwa kwesihlalo lunciphisa ukunyakaza okugqithisileyo kwesihlalo.
Uxinzelelo kwicala lokufaka:
Uxinzelelo lujika isihlalo siye phambili, nto leyo eyandisa amandla okuvala. Ukufakwa kwindawo yokugoba kwenzelwe ukuvumela ukujikeleza kwesihlalo. Le yindlela ekhethwayo yokuqhoboshela.
Isihlalo seHigh Performance Butterfly Valve sinomsebenzi wememori. Isihlalo sibuyela kwimo yaso yokuqala emva kokulayisha. Amandla esihlalo okubuyela kwimo achazwa ngokulinganisa ukuguquka okusisigxina kwesihlalo. Ukuguquka okuphantsi okusisigxina kuthetha ukuba izinto zinememori engcono - azinangxaki yokuguquka okusisigxina xa umthwalo ufakwa. Ngenxa yoko, ukulinganisa ukuguquka okuphantsi okusisigxina kuthetha ukuphuculwa kokubuyiselwa kwesihlalo kunye nexesha elide lokuphila kwesitywina. Oku kuthetha ukuphuculwa kokuvalwa phantsi koxinzelelo kunye nokujikeleza kobushushu. Ukuguquka kuchaphazeleka bubushushu.
Ukupakisha isiqu kunye noyilo lweebhereyitha
Ingongoma yokugqibela yokuthelekisa sisitywino esithintela ukuvuza kwangaphandle kwindawo yesiqu.
Njengoko ubona ngezantsi, iivalvu ezifakwe ngerabha zine-stem seal elula kakhulu, engaguqukiyo. Uyilo lusebenzisa i-stem bushing ukumisa phakathi kwe-shaft kunye nee-U-cups ezimbini zerabha ukuvala i-medium ukuthintela ukuvuza.
Akukho hlengahlengiso lwenziwayo kwindawo evaliweyo, oko kuthetha ukuba ukuba kukho ukuvuza, ivalvu kufuneka isuswe kumgca kwaye ilungiswe okanye itshintshwe. Indawo esezantsi yeshaft ayinayo inkxaso yesiqu, ngoko ke ukuba amasuntswana aya kwindawo ephezulu okanye esezantsi yeshaft, i-drive torque iyaphakama, nto leyo ebangela ukuba kube nzima ukusebenza.
Iivalvu zeButterfly ezisebenza kakuhle eziboniswe ngezantsi zenzelwe ukupakisha okuhlengahlengiswayo ngokupheleleyo (itywina leshaft) ukuqinisekisa ukuba ixesha elide lokusebenza kwaye akukho kuvuza kwangaphandle. Ukuba kukho ukuvuza okwenzekayo ngokuhamba kwexesha, ivalvu ine-packing gland ehlengahlengiswayo ngokupheleleyo. Jika kuphela iringi ye-nut ngexesha de kuphele ukuvuza.
✧ Iingenelo zeValve yeButterfly eSebenza kakuhle
Ngexesha lenkqubo yokuvula nokuvala ivalvu yeglobhu yentsimbi eyenziweyo, kuba ukungqubana phakathi kwediski nomphezulu wokutywina womzimba wevalvu kuncinci kunokwevalvu yesango, ayigugi.
I-stroke yokuvula okanye yokuvala yesiqu sevalvu imfutshane kakhulu, kwaye inomsebenzi wokunqunyulwa othembekileyo kakhulu, kwaye ngenxa yokuba utshintsho lwesango lesihlalo sevalvu luhambelana ne-stroke yediski yevalvu, lufanelekile kakhulu ekulungiseni isantya sokuhamba. Ke ngoko, olu hlobo lwevalvu lufanelekile kakhulu ekunqunyulweni okanye ekulawuleni nasekugobeni.
