Ivalvu yeBhola vs Ivalvu yeSango: Uthelekiso lwabavelisi

Iivalvu zoshishinozibalulekile ekulawuleni ukuhamba kolwelo kwimibhobho, kodwa ukukhetha uhlobo olufanelekileyo kuxhomekeke ekuqondeni iimpawu zazo ezikhethekileyo. Iivalvu ezimbini ezisetyenziswa kakhulu—Ivalvu yeBhola vs Ivalvu yeSango—zisebenza ngeenjongo ezahlukeneyo. Eli nqaku liphonononga iinkcazo zazo, izakhiwo, imisebenzi, iimeko ezifanelekileyo zokusetyenziswa, abavelisi, kunye namaxabiso ukukunceda wenze izigqibo ezinolwazi.

Xa kufikwa kwizicelo zoshishino, ukhetho phakathiIvalvu yebhola kunyeIvalvu yesangoibalulekile kubavelisi. Zombini ezi ntlobo zeevalvu zisebenza imisebenzi ebalulekileyo ekulawuleni ukuhamba kolwelo, kodwa zineempawu ezahlukileyo ezenza zilungele iimeko ezahlukeneyo. 

Iinkcazo: Zithini iiValve zeBhola kunye neeValve zeSango 

Iivalvu zeBhola

Aivalvu yebholaisebenzisa ibhola ejikelezayo enebhore ukulawula ukuhamba kolwelo. Xa isiphatho silungelelanisa ibhore nombhobho, ivalvu iyavuleka; ukuyijikelezisa ngeedigri ezingama-90 kuyayicima indlela yokuhamba. Iivalvu zebhola zaziwa ngokusebenza ngokukhawuleza kunye nokuvala ngokuqinileyo.

Iivalvu zeSango

Aivalvu yesangoisebenzisa isango elityibilikayo (idiski ethe tyaba okanye efana ne-wedge) ukuqala okanye ukumisa ukuhamba. Isango lihamba ngokuthe nkqo kwicala lolwelo, nto leyo eyenza ukuba lilungele ukusetyenziswa xa livuliwe/licinyiwe kodwa lingafanelekanga xa licinezelwa.

Uthelekiso lweSakhiwo: Uyilo kunye neeCandelo

Ulwakhiwo lweValve yeBhola

Umzimba weValve yeBhola:Incinci, ineziphelo ezifakwe imisonto okanye ezijijekileyo.

Izicelo: Amatyala okusetyenziswa afanelekileyo 

Ixesha lokusebenzisa iiValve zeBhola

Amashishini:Ioyile negesi, ukucutshungulwa kweekhemikhali, i-HVAC.

Imeko:Ukusebenza rhoqo, ukuvala ngokuqinileyo (umz., imigca yegesi), ulwelo olubolayo.

Ixesha lokusebenzisa iiValve zeSango

Amashishini:Unyango lwamanzi, izikhululo zombane, ukumbiwa kwemigodi.

Imeko:Iimfuno zokuhamba ngokupheleleyo/ukungabikho kwemiqathango (umz., imibhobho yamanzi), ukusebenza okungaxhaphakanga.

Uthelekiso loMvelisi: Iimpawu eziPhambili 

Abavelisi beValve yeBhola ephezulu

1. UEmerson (uFisher):Iivalvu ezisebenza kakuhle kwiindawo ezinobungozi.

2. Inkonzo yokusasaza:Uyilo olunokulungiselelwa ukusetyenziswa kwimizi-mveliso.

3. Iivalvu ze-APOLLO:Iindawo zokuhlala/iindlela zorhwebo ezingabizi kakhulu.

4. Iivalvu zaseNSW: Umenzi weValve yeBhola yokuSebenza evela eTshayina

Abavelisi beValve yeSango eliPhezulu

1. UVelan:Iivalvu ezinzima zokuvelisa umbane.

2. Ubunjineli beeKreyini:Izinto ezimelana nokugqwala.

3. IVALVU YE-NSWAmava eminyaka engama-20 kwi-Gate Valve Manufacturing

Uthelekiso lwamaxabiso: Iindleko zokuqala nezexesha elide 

Iivalvu zeBhola:Iindleko eziphezulu kwangaphambili (50–500+) ngenxa yobunjineli obuchanekileyo kunye nezitywini. Iindleko zokugcina izinto ziphantsi ngokuhamba kwexesha.

Iivalvu zeSango:Ixabiso liphantsi ekuqaleni (30–300 nangaphezulu) kodwa kusenokufuneka isihlalo/isango litshintshwe rhoqo

Yeyiphi iValve Ofanele Uyikhethe 

Khetha iivalvu zebholaukuze isebenze ngokukhawuleza, ivalwe ngokuqinileyo, kwaye isetyenziswe rhoqo.

Khetha iivalvu zesangokwiinkqubo ezinoxinzelelo oluphezulu ezinemida encinci yokuhamba kwamanzi.

Ngokuvavanya izinto ezinje ngoxinzelelo, uhlobo lolwelo, kunye nokuphindaphinda kokusebenza, ungakhetha ivalvu ephucula ukusebenza kakuhle kunye nokunciphisa iindleko kwiprojekthi yakho.

Ulwazi loMvelisi weValve yeBhola

Iivalvu zebhola zaziwa ngokusebenza kwazo ngokukhawuleza kunye nokukwazi kwazo ukuvala kakuhle.umenzi wevalvu yebholaNgokwesiqhelo igxininisa ubulula boyilo, oluvumela ulawulo olulula lokuvula/ukucima kunye nokunciphisa uxinzelelo. Idiski engqukuva, okanye ibhola, ngaphakathi kwevalvu iyajikeleza ukuvumela okanye ukuvala ukuhamba, okwenza ukuba ilungele ukusetyenziswa okufuna ukuvalwa ngokukhawuleza. Ukongeza, iivalvu zebhola zihlala ixesha elide kwaye zinokusingatha iindawo ezinoxinzelelo oluphezulu, nto leyo eyenza ukuba zibe lukhetho olukhethwayo kumashishini afana neoyile negesi, unyango lwamanzi, kunye nokulungiswa kweekhemikhali.

Izinto ekufuneka uziqwalasele xa usenza iSango leValve

Kwelinye icala, iivalvu zesango zenzelwe ukusetyenziswa ngokupheleleyo.umenzi wevalvu yesangoidla ngokubonisa amandla evalvu okubonelela ngokuhamba komgca othe tye ngokumelana okuncinci. Ngokungafaniyo neevalvu zebhola, iivalvu zesango azifanelekanga kwiinjongo zokubhoboza, njengoko zinokubangela ukuxinana kunye nokuguguleka. Nangona kunjalo, zibalasele kwizicelo apho kufuneka ukuvala ngokupheleleyo, njengakwiipayipi kunye neenkqubo zamanzi ezinkulu. Indlela yesango ivumela ukuvalwa okuqinileyo, okuthintela ukuvuza xa ivaliwe ngokupheleleyo.

Isiphelo

Ukhetho phakathiivalvu yebhola vs ivalvu yesangokuxhomekeke kwiimfuno ezithile zesicelo. Iivalvu zebhola zilungele ukuvalwa ngokukhawuleza kunye neemeko zoxinzelelo oluphezulu, ngelixa iivalvu zesango zilungele ngcono usetyenziso olufuna ukumelana okuncinci kokuhamba kwamanzi. Abavelisi kufuneka baqwalasele ngononophelo ezi zinto xa bekhetha uhlobo olufanelekileyo lweevalvu kwiiprojekthi zabo, beqinisekisa ukusebenza kakuhle kunye nokuthembeka kwiinkqubo zabo.
