Ngaba iivalve zebhabhathane zibuyela kabini?

I-Butterfly Valve luhlobo lwesixhobo sokulawula ukuhamba ngekota-turn motion motion , Isetyenziswa kwimibhobho yokulawula okanye ukwahlula ukuhamba kolwelo ( ulwelo okanye iigesi ) , Nangona kunjalo, umgangatho olungileyo kunye nokusebenza ivelufa yebhabhathane kufuneka ixhotyiswe ukutywinwa okulungileyo. . Ngaba iivalve zebhabhathane zibuyela kabini? Ngokwesiqhelo sahlulahlula ivalve yebhabhathane ibe ziivalve zebhabhathane eziNxibelele kunye nevalve yebhabhathane eccentric.
Siza kuxoxa malunga nevalve yebhabhathane elungeleleneyo bidirectional njengalapha ngezantsi:

Yintoni ivalve yebhabhathane eNxibeleleyo?

Ivalve yebhabhathane econcentric yazi njengeevalufa zebhabhathane ezikwaziyo ukumelana nezihlalo okanye zero-offset zebhabhathane , Amalungu azo abandakanya :Ivalve yomzimba , idiski , isihlalo , isiqu kunye netywina . i-shaft okanye isiqu sisembindini wediski . Oku kuthetha ukuba i-disc ijikeleza ngaphakathi kwesihlalo esithambileyo, Izinto zokuhlala zingabandakanya i-EPDM, i-NBR Viton Silicon Teflon Hypalon okanye i-elastomer.

Isebenza njani ivalve yebhabhathane egxininisiweyo?

Ukwakhiwa kwevalve yebhabhathane kulula kakhulu , kukho iindlela ezintathu ze actuator yokusebenza :I-Lever Handle yobukhulu obuncinci , Ibhokisi ye-Worm Gear yeevalvu ezinkulu ukwenza kube lula ukulawula kunye nokusebenza okuzenzekelayo ( kubandakanywa i-Actuator yoMbane kunye ne-Pneumatic )
Ivalve yebhabhathane isebenza ngokujikelezisa idisk (okanye ivane) ngaphakathi kombhobho ukulawula ukuhamba kolwelo. I-disk ifakwe kwi-stem edlula kumzimba we-valve, kwaye ukuguqula i-stem ijikeleze i-disk ukuba ivule okanye ivale i-valve, Njengoko i-shaft ijikeleza, i-disc ivula indawo evulekileyo okanye evulekileyo, ivumela ulwelo ukuba luhambe ngokukhululekileyo. Kwindawo evaliweyo, i-Shaft ijikeleza i-disc ukuvala ukuhamba ngokupheleleyo kunye nokutywina i-valve.

Ngaba iivalve zebhabhathane zibuyela kabini?

I-Bidirectional-indlela inokulawula ukuhamba kumacala omabini ,Njengoko besithetha , umgaqo osebenzayo weevalvu unokufikelela kwiimfuno .Ngoko iivalve zebhabhathane ezigxininisiweyo zineendlela ezimbini , Zininzi iinzuzo zokusebenzisa ivalve yebhabhathane ephakathi .
1 Iyonga kakhulu kunolunye uhlobo lwevalvu ngenxa yoyilo lwazo olulula kunye nemathiriyeli embalwa efunekayo kulwakhiwo . Ukongiwa kweendleko kubonakaliswa ubukhulu becala kwiivalvu ezinkulu.
2 Ukusebenza ngokulula, ukufakwa kunye nokugcinwa, ukulula kwevalve yebhabhathane kwenza kube lula kwaye kukhawuleze ukuyifaka, inokunciphisa iindleko zabasebenzi, Uyilo olulula ngokwendalo, oluneendawo ezimbalwa ezihambayo, kwaye ngenxa yoko iindawo zokunxiba ezimbalwa, kunciphisa kakhulu ukugcinwa kwazo. iimfuno.
3 Uyilo olukhaphukhaphu kunye nolucwengekileyo kunye nobuso obuncinci ukuya kobuso umlinganiso wevalve yebhabhathane egxininisiweyo, Ikwazi ukufakwa kwaye isetyenziswe kwindawo enomda wesithuba, Zifuna indawo encinci xa kuthelekiswa nezinye iindidi zevalvu, njengesango okanye iivalvu zeglowubhu, kwaye ukubumbana kwazo kwenza kube lula. zombini ufakelo kunye nokusebenza , ngakumbi kwiinkqubo ezipakishwe ngokuxineneyo .
4 Ukusebenza ngokukhawuleza, i-angle-engile (i-90-degree) uyilo olujikelezayo lubonelela ngokuvula nokuvala ngokukhawuleza. Olu phawu lubalulekile kwii-aplikeshini apho impendulo ekhawulezayo iyimfuneko, njengakwiinkqubo zokuvala kaxakeka okanye iinkqubo ezineemfuno zolawulo ezichanekileyo. Ukukwazi ukuvula nokuvala ngokukhawuleza kwandisa ukuphendula kwenkqubo, ukwenza iivalve zebhabhathane ezigxininisiweyo zifaneleke ngakumbi ukulawulwa kokuhamba kunye nokulawula / ukuvala kwiinkqubo ezifuna ixesha eliphezulu lokusabela.

Okokugqibela, ivalve yebhabhathane emacala omabini eneempawu zokutywina zombini ngenxa yokutywinwa kwayo okulastiki phakathi kwesitulo sevalve kunye nediski yebhabhathane, Ukuqinisekisa ukutywinwa okungaguquguqukiyo nokuba ulwelo luya ngakulo icala.
