Amavalvu angamathuluzi ajwayelekile emkhakheni wokulawula uketshezi futhi asetshenziselwa ukulawula ukugeleza koketshezi. Ngokusho kwesakhiwo nokusebenza kwawo, ama-valve angahlukaniswa abe yizinhlobo eziningi. Okulandelayo ngumkhiqizi we-valve we-Tianjin ukwethula isakhiwo nokuhlukaniswa kwe-valve:
Okokuqala, isakhiwo se-valve:
1. Umzimba we-valve: ingxenye eyinhloko ye-valve, enesibopho sokulungisa nokusekela ezinye izingxenye.
2. I-valve disc (idiski) : Ingxenye elawula ukuvulwa nokuvalwa kwevalvu ukuze kugeleze uketshezi.
3. Isihlalo se-valve: ne-disc ukwenza uphawu, ukulawula uketshezi nokuvala.
4. Indawo yokuvala: indawo yokuxhumana phakathi kwe-valve disc kanye nesihlalo, ngokusebenzisa indawo yokuvala ukuze kuzuzwe ukusebenza kokuvala kwe-valve.
5. I-rod shaft: ixhunywe ne-valve disc ukudlulisa amandla okusebenza nokulawula ukuvulwa nokuvalwa kwe-valve.
6. Idivayisi yokusebenza: esetshenziselwa ukulawula ukushintshwa kwe-valve, ingabandakanya idivayisi yokusebenza ngesandla, idivayisi kagesi, idivayisi yomoya, njll.
Okwesibili, ukuhlukaniswa kwama-valve:
1. Ukuhlukaniswa ngokwesakhiwo:
- Ama-valve ekhathalogi: i-disc noma i-disc iya phezulu naphansi eksisi ngomugqa oqondile, njengama-globe valves, ama-valve okuhlola, njll.
- I-valve yokuxhuma: i-disc noma i-disc izungeza i-eksisi, njengama-valve ebhola, ama-butterfly valves, njll.
- I-valve yokumelana okuphezulu: Engeza iziteshi ezincane ku-valve ukwandisa ukumelana nokugeleza kwamanzi, njengama-throttle valve, ama-valve esango, njll.
2. Ukuhlukaniswa ngokusetshenziswa:
- Ivalvu yokumisa: isetshenziselwa ukulawula ukuvuleka nokuvala uketshezi, njengokumisa ukugeleza koketshezi noma ukulawula uketshezi.
- Hlola i-valve: isetshenziselwa ukuvimbela ukubuyela emuva koketshezi, ukuvimbela ukugeleza kokuhlehla.
- Ivalvu yokulawula: isetshenziselwa ukulawula izinga lokugeleza, ingcindezi noma izinga lokushisa loketshezi.
- Ivalvu yokuphepha: isetshenziselwa ukukhulula ingcindezi lapho ingcindezi idlula inani elibekiwe ukuze kugwenywe ukulimala kwezinto zokusebenza noma amapayipi.
- Ivalvu yokukhipha umoya: isetshenziselwa ukukhipha igesi epayipini ukuze kuqinisekiswe ukusebenza okuvamile koketshezi.
3. Ngokusebenzisa ukuhlukaniswa kwemidiya:
- I-valve yamanzi: isetshenziselwa ukulawula ukugeleza kwamanzi, njenge-valve yokuhlinzeka ngamanzi, i-drainage valve, njll.
- I-valve yegesi: isetshenziselwa ukulawula ukugeleza kwegesi, njenge-valve yokulawula igesi, i-pneumatic ball valve, njll.
- I-valve yamafutha: isetshenziselwa ukulawula ukugeleza kukawoyela, njenge-valve yokulawula i-hydraulic, i-valve yophawu lwamafutha, njll.
- I-Steam valve: isetshenziselwa ukulawula ukugeleza kwesitimu, njenge-valve elawula umusi, i-valve yamandla omusi, njll.
4. Hlukanisa ngezinga lokucindezeleka:
- I-valve yokucindezela okuphansi: ifanele indawo yokusebenza enengcindezi ephansi, ngokuvamile ingaphansi kwe-1.6MPa.
- I-valve yokucindezela okuphakathi: ifanele indawo yokusebenza yengcindezi ephakathi, ngokuvamile phakathi kwe-1.6MPa ne-10MPa.
- I-valve yokucindezela okuphezulu: ifanele indawo yokusebenza enomfutho ophezulu, ngokuvamile ingaphezu kuka-10MPa.
Okungenhla yisakhiwo nokuhlukaniswa kwe-valve. Lapho ukhetha i-valve efanele, kuyadingeka ukucabangela ngokucophelela izidingo ezithile zobunjiniyela kanye nezici zemidiya, bese ukhetha umenzi we-valve wekhwalithi ephezulu ukuqinisekisa ukwethembeka nokuphila kwesevisi ye-valve. Ukuze uthole ukubonisana okuningiliziwe kanye nesiqondiso, kunconywa ukuthi uxhumane nabakhiqizi be-valve abangochwepheshe.
