Yintoni iValve yeSango kwiPlumbing
A ivalvu yesangolicandelo elibalulekileyo kwiinkqubo zemibhobho kunye nemibhobho, eyilelwe ukulawula ukuhamba kolwelo okanye iigesi ngokunyusa okanye ukwehlisa "isango" elithe tyaba (idiski efana ne-wedge okanye ehambelanayo) ngaphakathi komzimba wevalvu. Xa ivuliwe ngokupheleleyo, isango libuyela umva kwibhonethi yevalvu, livumela ukuhamba okungenamkhawulo. Xa ivaliwe, isango livala izihlalo emzimbeni wevalvu, limise ukuhamba ngokupheleleyo. Iivalvu zesango zisetyenziselwa ikakhuluusetyenziso oluvuliweyo/olucinyiweyoendaweni yokulawula ukuhamba kombane, nto leyo eyenza ukuba zilungele iinkqubo apho kufuneka ukuhamba kombane ngokupheleleyo okanye ukucima ngokupheleleyo.
Iimpawu eziphambili zeeValve zeSango
- Uyilo Oluhlala Luhleli:Yakhelwe iindawo ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu.
- Ukumelana Nokuhamba Okuphantsi:Uxinzelelo oluncinci luyehla xa luvuliwe ngokupheleleyo.
- Ukuhamba kweendlela ezimbini:Ingafakwa kwicala ngalinye lokuhamba komoya.
- Izixhobo eziqhelekileyo:I-brass, i-cast iron, i-stainless steel, okanye i-PVC, kuxhomekeke kwindlela esetyenziswa ngayo.
IiValve zeSango vs. IiValve zeBhola: Umahluko oPhambili
Nangona zombini iivalvu zesango kunye neevalvu zebhola zisebenza njengezixhobo zokulawula ukuhamba kwamanzi, uyilo lwazo kunye neemeko zokusetyenziswa zahlukile kakhulu:
| Uphawu | Ivalvu yeSango | Ivalvu yeBhola |
| Umsebenzi | Intshukumo ethe tye (isango liya phezulu/ezantsi). | Intshukumo yokujikeleza (ibhola ijikeleza ngama-90 degrees). |
| Ulawulo lokuhamba kwamanzi | Ukuvula/ukucima kuphela; hayi okokucinezela. | Ifanelekile ukuvula/ukucima kunye nokuhamba okungaphelelanga. |
| Ukuqina | Idla ngokunxitywa xa isetyenziselwa ukuqhobosha. | Ihlala ixesha elide xa isebenza rhoqo. |
| Ixabiso | Ngokwesiqhelo ixabisa kancinci kwiidayamitha ezinkulu. | Ixabiso liphezulu, kodwa ixesha elide lokuphila. |
| Iimfuno Zendawo | Uyilo olude ngenxa yokuhamba kwesiqu. | Incinci kwaye ayisebenzisi kakhulu indawo. |
Ukukhetha nini iValve yeSango:
- Kwiinkqubo ezifuna ukuhamba kwamanzi ngokupheleleyo okanye ukusebenza okungacwangciswanga rhoqo (umz., imibhobho yamanzi ephambili).
- Kwiindawo ezinobushushu obuphezulu okanye ezinoxinzelelo oluphezulu.
Ukukhetha iValve yeBhola nini:
- Kwiinkqubo ezifuna ukusebenza rhoqo okanye ukulungiswa kokuhamba kwamanzi.
- Kwimibhobho yamanzi okanye imigca yegesi yokuhlala.
Abavelisi beValve yeSango: Abadlali abaPhambili
Iivalvu zesango ziveliswa ngabavelisi abaninzi behlabathi nabakwimimandla. Imigangatho yomgangatho, ukhetho lwezinto eziphathekayo, kunye neziqinisekiso (umz., i-ISO, i-ANSI, i-API) zezona zinto zibalulekileyo xa ukhetha umthengisi.
Abavelisi beValve yeSango abaPhambili
1. U-Emerson (ASCO):Yaziwa ngeevalvu zodidi lwemizi-mveliso ezinobunjineli obuchanekileyo.
2. Inkampani yeCrane:Ibonelela ngeendidi ezahlukeneyo zeevalvu kwiindawo ezinzima.
3. I-AVK yamazwe ngamazwe:Ingcali kwiivalvu zokusasazwa kwamanzi negesi.
4. I-Velan Inc.:Inkokeli yehlabathi kwiivalvu ezisebenza kakuhle.
5. Inkampani yaseNSW:Umenzi weeValve zobungcali oneFektri yeeValve zeBhola, iFektri yeeValve zeSango, iFektri yeeValve zeCheck/Globe/Plug/Butterfly kunye neFektri ye-actuator yePneumatic
Ushishino lweeValve zeSango laseTshayina: I-Global Hub
I-China ivele njengomdlali ophambili kwimveliso yeevalvu zesango, idibanisaukusebenza kakuhle kweendlekokunye nemigangatho ephucukileyo yomgangatho. Iingenelo eziphambili ziquka:
- Amaxabiso akhuphisanayo:Iindleko zabasebenzi nemveliso ziphantsi xa kuthelekiswa neemarike zaseNtshona.
- Ukukhula:Ubuchule bokuvelisa imiqulu emikhulu ukuze isasazwe kwihlabathi liphela.
- Uphuhliso lweTekhnoloji:Ukwamkelwa koomatshini be-CNC kunye nokuhlolwa komgangatho ozenzekelayo.
- Ubunkokeli bokuthumela kwamanye amazwe:Iimpawu zaseTshayina ezifanaI-SUFA, Ivalvu ye-NSWkunyeI-Yuanda Valvezisetyenziswa kakhulu kwiinkqubo zokunyanga amanzi, ioyile negesi, kunye neenkqubo ze-HVAC kwihlabathi liphela.
Izinto ekufuneka uziqwalasele xa uthenga ivenkile eTshayina:
- Qinisekisa iziqinisekiso (umz., ISO 9001, CE, API).
- Cela iingxelo zovavanyo lwezinto (ii-MTR) kwizicelo ezibalulekileyo.
- Sebenzisana nabathengisi abathembekileyo ukuze uphephe iimveliso zomgunyathi.
Isiphelo
Iivalvu zesango zihlala zibalulekile kwiinkqubo zemibhobho ukuze zivaleke ngokuthembekileyo kwiindawo ezifuna amandla amaninzi. Ngelixa iivalvu zebhola zibalasele ngokuguquguquka kunye nokulula kokusetyenziswa, iivalvu zesango azinakuthelekiswa nokusetyenziswa koxinzelelo oluphezulu, oluhamba ngokupheleleyo. Njengoko iTshayina ilawula icandelo lemveliso yeevalvu zehlabathi, abathengi banokufikelela kwiivalvu zesango ezikumgangatho ophezulu ngamaxabiso akhuphisanayo—ukuba nje babeka phambili ababoneleli abaqinisekisiweyo kunye nokuhlolwa komgangatho okungqongqo.
Ngokuqonda amandla eevalvu zesango kunye nabavelisi bazo, iingcali zemibhobho zinokwenza izigqibo ezinolwazi ezilungiselelwe iimfuno zenkqubo yazo.
