Yiziphi izinhlobo zama-valve?

i-valve iyisisetshenziswa esiwumshini esilawula ukugeleza, isiqondiso, ingcindezi, izinga lokushisa, njll. yendawo yoketshezi egelezayo. I-valve iyingxenye eyisisekelo ohlelweni lwamapayipi. Ukufakwa kwamavalvu kuyafana ngokobuchwepheshe namaphampu futhi kuvame ukuxoxwa njengesigaba esihlukile. Ngakho yiziphi izinhlobo zama-valve? Ake sibheke ndawonye.

Njengamanje, izindlela ezisetshenziswa kakhulu zokuhlukanisa ama-valve emazweni ngamazwe nasekhaya yilezi ezilandelayo:

1. Ngokwezici zesakhiwo, ingahlukaniswa ngokuya kokuqondisa kwelungu elivalayo ngokuhlobene nesihlalo se-valve:

1. Ukuma kwesango lesigaba: Ucezu oluvalayo luhamba phakathi nendawo yesihlalo sevalvu.

2. Isimo sesango: Ucezu oluvalayo luhamba phakathi nendawo yesihlalo sevalvu eqondile.

3. Iqhude nebhola: Ingxenye yokuvala i-plunger noma ibhola, elizungeza umugqa ophakathi nendawo.

4. Swing shape; ucezu lokuvala luzungeza i-eksisi ngaphandle kwesihlalo se-valve.

5. Isimo sesitsha: Idiski yelungu elivalayo izungeza i-eksisi esesihlalweni sevalvu.

6. Umumo wevalvu yesilayidi: Ucezu oluvalayo luslayida luye ohlangothini olubheke esiteshini.

2. Ngokwemodi yokushayela, ingahlukaniswa ngezinhlobo ezahlukene zokushayela:

1. Ugesi: Ishayelwa izinjini noma ezinye izinto zikagesi.

2. I-Hydraulic: iqhutshwa (amanzi, amafutha).

3. I-pneumatic; sebenzisa umoya ocindezelwe ukushayela i-valve ukuvula nokuvala.

4. Imanuwali: Ngosizo lwesondo lesandla, isibambo, i-lever noma i-sprocket, njll., iqhutshwa ngabasebenzi, futhi lapho i-torque yokudlulisela inkulu, ifakwe igiya lezikelemu, igiya namanye amadivaysi okunciphisa amandla.

Okwesithathu, ngokwenhloso, ngokwezinjongo ezahlukene ze-valve zingahlukaniswa zibe:

1. Ngokuphulwa: kusetshenziselwa ukuxhuma noma ukusika imidiya yamapayipi, njengama-valve eglobhu, ama-valve esango, ama-ball valve, ama-butterfly valves, njll.

2, ukusetshenziswa okungabuyiseli: kusetshenziselwa ukuvimbela okuphakathi ukuthi kungagelezi emuva, njenge-valve yokuhlola.

3, ukulungiswa: okusetshenziselwa ukulungisa ingcindezi nokugeleza kwe-medium, njenge-valve yokulawula, i-valve yokunciphisa ingcindezi.

4. Ukusabalalisa: kusetshenziselwa ukuguqula isiqondiso sokugeleza kwe-medium futhi kusabalalise okuphakathi, njengeqhude elinezindlela ezintathu, i-valve yokusabalalisa, i-valve yesilayidi, njll.

5. I-valve yokuphepha: Uma ingcindezi yendawo ephakathi idlula inani elishiwo, isetshenziselwa ukukhipha okuphakathi okweqile ukuze kuqinisekiswe ukuphepha kwesistimu yamapayipi nezinto zokusebenza, njengama-valve okuphepha nama-valve ezimo eziphuthumayo.

6. Ezinye izinjongo ezikhethekile: njengezicupho, ama-valve okukhipha umoya, ama-drain valve, njll.
