Iimveliso
Ivalvu yeButterfly eSebenzayo ePhakamileyo
✧ Inkcazo
I-High Performance Butterfly Valve yethu yivalvu yokujika kabini (ephindwe kabini) eyilwe ngekota yokujika eyenzelwe inkonzo ethembekileyo yokuvula/ukuvala kunye nokuqhobosha. Inika ukuvalwa okuqinileyo, i-torque ephantsi yokusebenza, kunye nobomi benkonzo ende - enye indlela engabizi kakhulu kuneevalvu zebhola okanye zeplagi.
Njengomvelisi weevalvu zeebhabhathane zobungcali, sinikezela ngobukhulu obuqala kwi-2″ ukuya kwi-48″ (DN50–DN1200), iiklasi zoxinzelelo eziyi-150, 300, kunye ne-600, kunye neentambo ze-wafer, i-lug, okanye i-flanged.
✧ Kutheni Ufanele Ukhethe Le Valve Yebhabhathane Esebenza Kakhulu?
•Uyilo lwe-offset kabini– Idiski iphakamisa isihlalo ngaphakathi kwe-7°, inciphisa ukuguguleka kwaye inciphisa i-torque.
•Ukutywinwa kweendlela ezimbini– Izihlalo ze-PTFE, RTFE, okanye zesinyithi ziqinisekisa ukuba akukho kuvuza (iKlasi VI).
•Iphedi yokufakela ye-ISO 5211– Ukufakelwa kwe-actuator ngqo ngaphandle kwezibiyeli ezongezelelweyo.
•Izixhobo– Intsimbi yekhabhoni yeWCB, intsimbi engagqwaliyo yeCF8/CF8M, i-duplex, kunye neenketho ze-alloy.
•Uluhlu lobushushu– Izihlalo ze-PTFE: -29°C ukuya kuma-200°C; izihlalo zesinyithi: -196°C ukuya kuma-550°C.

✧ Fumana iKoteshini yeXabiso Namhlanje
✧ Ulwazi lweeValve zeButterfly ezisebenza kakuhle - Iqela leNjineli yoMvelisi weeValve zaseNSW
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 oluSebenza ngokuPhezulu
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 seValve
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:
1. Emva kokuhlanganiswa:
Xa ihlanganiswe ngaphandle koxinzelelo, isihlalo sisebenza ngepleyiti yebhabhathane. Oku kuvumela ukutywinwa kweqamza ukusuka kwinqanaba le-vacuum ukuya kwinqanaba eliphezulu loxinzelelo lwevalvu.
2. Uxinzelelo lwe-Axial:
Iprofayili yesihlalo se-G idala isitywino esiqinileyo njengoko ipleyiti ishukuma. Uyilo lokufakwa kwesihlalo lunciphisa ukunyakaza okugqithisileyo kwesihlalo.
3. Uxinzelelo kwicala lokufaka:
Uxinzelelo lujika isihlalo siye phambili, lukhulisa amandla okuvala. Ukufakwa kwindawo yokugoba kwenzelwe ukuvumela ukujikeleza kwesihlalo. Le yindlela ekhethwayo yokufakela. Isihlalo seValve yeButterfly eSebenzayo ePhakamileyo sinomsebenzi wememori. Isihlalo sibuyela kwimo yaso yokuqala emva kokulayisha. Amandla esihlalo okubuyela kwimeko yaso yangaphambili achazwa ngokulinganisa ukuguquka okusisigxina kwesihlalo. Ukuguquka okuphantsi okusisigxina kuthetha ukuba izinto zinememori engcono - azinangxaki yokuguquka okusisigxina xa kufakwa umthwalo. 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.
• Uyilo lokuPakisha iStem kunye neeBearing
Ingongoma yokugqibela yokuthelekisa sisitywino esithintela ukuvuza kwangaphandle kwindawo yesiqu.
Njengoko ubona ngezantsi, iivalvu ezinerabha 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 ye-shaft esezantsi ayinayo inkxaso ye-stem, ngoko ke ukuba amasuntswana aya kwindawo ye-shaft ephezulu okanye esezantsi, 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.
