I-Butterfly Valve vs Ball Valve: Isikhokelo sokuthelekisa

Ekuthengweni kweemveliso zoshishino, iivalvu zebhola kunye neevalvu zebhabhathane ziintlobo zeevalvu eziqhelekileyo, nganye inomgaqo wayo wokusebenza owahlukileyo kunye neemeko ezifanelekileyo.

Yintoni ivalvu yebhola

IIvalvu yeBholaIlawula ulwelo ngokujikelezisa ibhola, kwaye ukusebenza kwayo kokutywina kugqwesile, ngakumbi kufanelekile kwiimeko zokusebenza ezinobushushu obuphezulu, uxinzelelo oluphezulu kunye nemidiya ye-viscosity ephezulu. Ulwakhiwo lwayo luquka umzimba wevalvu, ibhola, iringi yokutywina kunye nezinye izinto, kwaye ibhola kunye nesihlalo sevalvu zihambelana ngokusondeleyo ukuqinisekisa isiphumo sokutywina.

Yintoni ivalvu yebhabhathane

IIvalvu yebhabhathaneIlawula ulwelo ngokujikelezisa ipleyiti yebhabhathane. Inesakhiwo esilula, kulula ukuyifaka, ingabizi kwaye iyasebenza, kwaye ifanelekile ngakumbi kwiimeko zemidiya eziphantsi koxinzelelo kunye ne-viscosity ephantsi, ezifana nokucoca amanzi, i-petrochemical kunye neminye imboni.

Xa ivalvu yebhabhathane ivuliwe, iya kuvelisa ukumelana okuthile nolwelo, ngoko ke ifaneleke ngakumbi kwindawo ethontsiza uxinzelelo oluphantsi. Ulwakhiwo lwayo ikakhulu lwenziwe ngepleyiti yebhabhathane, isiqu sevalvu, isihlalo sevalvu, njl.njl., kwaye inqanaba lokuvula lepleyiti yebhabhathane linokulungiswa ngokulula. Ivalvu yebhola isetyenziswa kakhulu kwiindawo zoshishino ezifuna ukutywinwa okungqongqo kunye nendawo exinezelekileyo ngenxa yokuxhathisa kwayo uxinzelelo oluphezulu, ubushushu obuphezulu kunye nemidiya ye-viscosity ephezulu.

Ukuthelekiswa kweenkcukacha ezithile phakathi kwevalvu yebhabhathane kunye nevalvu yebhola

Ivalvu yebhabhathane kunye nevalvu yebhola zinomahluko omkhulu kwiinkalo ezininzi, kubandakanya ulwakhiwo, ukusebenza, iimeko zokusetyenziswa, njl.

Umahluko kwisakhiwo

Ivalvu yebhabhathane yenziwe kakhulu ngumzimba wevalvu, isihlalo sevalvu, ipleyiti yevalvu kunye nesiqu sevalvu, kwaye zonke izixhobo zayo zibonakala. Ivalvu yebhola yenziwe ngumzimba wevalvu, umongo wevalvu kunye nesiqu sevalvu, kwaye ulwakhiwo lwayo lwangaphakathi lubonakala kancinci.

Umahluko ekusebenzeni

‌1. Ukusebenza kokutywina‌:

Ukusebenza kokutywina kwevalvu yebhabhathane kubi kancinci kunevalvu yebhola, ingakumbi kwindawo enoxinzelelo oluphezulu. Ukuthembeka kokutywina kwevalvu yebhola kuphezulu, kwaye isenokugcina isiphumo sokutywina esizinzileyo emva kokutshintsha rhoqo.

2. I-torque yokusebenza:

I-torque yokusebenza yokuvula nokuvala yevalvu yebhola idla ngokuba nkulu kuneyevalvu yebhabhathane, kodwa ubomi bevalvu yebhola buhlala bude kuneyevalvu yebhabhathane. Ukumelana noxinzelelo: Iivalvu zebhola zihlala zilungele uxinzelelo oluphezulu, ukuya kuthi ga kwi-100 yeekhilogram, ngelixa uxinzelelo oluphezulu lweevalvu zebhabhathane lungama-64 eekhilogram kuphela.

3. Ulawulo lokuhamba kwamanzi:

Iivalvu zebhabhathane zinomsebenzi olungileyo wokulawula ukuhamba kwamanzi kwaye zifanelekile ukusetyenziswa njengeevalvu zokulawula; ngelixa iivalvu zebhola zisetyenziselwa kakhulu imisebenzi yokutshintsha, kwaye ukusebenza kokulawula ukuhamba kwamanzi kubi kancinci.

4. Ukuguquguquka kokusebenza:

Iivalvu zebhabhathane zinokuguquguquka okungcono kokusebenza kunye nesantya sokusebenza esicothayo; iivalvu zebhola zinzima kakhulu ukuzisebenzisa kodwa zikhawuleza xa zisebenza.

5. Umahluko wesimo sesicelo ‌ Ububanzi obusebenzayo ‌:

Iivalvu zebhabhathane zihlala zifanelekile kwiipayipi ezinkulu ngenxa yesakhiwo sazo esilula, ubunzima obulula, kunye nomgangatho omncinci; ngelixa iivalvu zebhola zisetyenziswa kakhulu kwiipayipi ezincinci neziphakathi.

6. Ukuguquguquka okuphakathi:

Iivalvu zebhabhathane zisebenza kakuhle kakhulu xa zithutha udaka kwaye zifanelekile kwiimeko ezinoxinzelelo oluphantsi kunye nobukhulu obukhulu; iivalvu zebhola zifanelekile kwiindawo ezahlukeneyo zolwelo, kuquka iindawo eziqulathe iifayibha kunye namasuntswana amancinci aqinileyo.

7.Uluhlu lobushushu:

Iivalvu zebhola zinoluhlu olubanzi lobushushu olusebenzayo, ngakumbi ukusebenza okuzinzileyo kwiindawo ezinobushushu obuphezulu; ngelixa iivalvu zebhabhathane zisebenza ngcono kwiindawo ezinobushushu obuphantsi

Isishwankathelo

Kukho umahluko omkhulu phakathi kweevalvu zebhola kunye neevalvu zebhabhathane ngokwesakhiwo, umgaqo wokusebenza, kunye neemeko ezifanelekileyo. Xa uthenga, kuyimfuneko ukukhetha ngokufanelekileyo uhlobo lwevalvu ngokweemeko ezithile zokusebenza kunye neemfuno ukuqinisekisa ukusebenza okuqhelekileyo kunye nokusebenza ngokufanelekileyo kwenkqubo.
