Iivalvu zizixhobo eziqhelekileyo kummandla wokulawula ulwelo kwaye zisetyenziselwa ukulawula ukuhamba kwamanzi. Ngokwesakhiwo kunye nomsebenzi wabo, iivalve zinokwahlulwa zibe ziindidi ezininzi. Oku kulandelayo ngumenzi wevalve yeTianjin ukwazisa ubume kunye nokuhlelwa kwevalve:
Okokuqala, isakhiwo sevalve:
1. Umzimba we-Valve: inxalenye ephambili ye-valve, ejongene nokulungisa nokuxhasa amanye amacandelo.
2. I-Valve disc (idiski) : Inxalenye elawula ukuvulwa kunye nokuvalwa kwevalve yokuhamba kwamanzi.
3. Isihlalo seValve: kunye nediski ukwenza itywina, ukulawula ulwelo kunye nokucima.
4. Umphezulu wokutywina: indawo yokudibanisa phakathi kwediski yevalve kunye nesihlalo, ngomphezulu wokutywina ukufezekisa ukusebenza kokutywinwa kwevalve.
5. I-rod shaft: idibaniswe ne-disc ye-valve ukudlulisa amandla okusebenza kunye nokulawula ukuvulwa kunye nokuvalwa kwevalve.
6. Isixhobo sokuSebenza: esisetyenziselwa ukulawula i-valve switch, ingabandakanya isixhobo sokusebenza ngesandla, isixhobo sombane, isixhobo somoya, njl.
Okwesibini, ukuhlelwa kweevalvu:
1. Ukuhlelwa ngokwefomu yolwakhiwo:
- Iivalve zekhathalogu: i-disc okanye i-disc ihamba inyuka kwaye ihla kwi-axis kumgca othe ngqo, njengama-valve eglowubhu, i-valve yokukhangela, njl.
-I-valve yeplagi: i-disc okanye i-disc ijikeleza i-axis, njengeevalve zebhola, i-butterfly valves, njl.
-I-valve ephezulu yokumelana: Yongeza iziteshi ezimxinwa kwi-valve ukwandisa ukunyanzeliswa kokuhamba kwamanzi, njengama-valve e-throttle, i-valve yesango, njl.
2. Ukuhlelwa ngokusetyenziswa:
- Ivalve yokumisa: isetyenziselwa ukulawula ulwelo oluvuliweyo noluvalayo, olufana nokumisa ukuphuma kwamanzi okanye ukulawula ulwelo.
- Khangela ivalve: isetyenziselwa ukuthintela ukubuyela ngasemva kolwelo, ukuthintela ukuhamba komqolo.
-Ivalve yokulawula: isetyenziselwa ukulawula izinga lokuhamba, uxinzelelo okanye ubushushu bolwelo.
- Ivalve yokhuseleko: isetyenziselwa ukukhulula uxinzelelo xa uxinzelelo ludlula ixabiso elimiselweyo ukuphepha umonakalo kwisixhobo okanye imibhobho.
- Ivalve yokukhupha: isetyenziselwa ukususa igesi kumbhobho ukuqinisekisa ukusebenza okuqhelekileyo kolwelo.
3. Ngokusetyenziswa kokuhlelwa kwemidiya:
-Ivalve yamanzi: isetyenziselwa ukulawula ukuhamba kwamanzi, njengevalve yokubonelela ngamanzi, ivalve yokuhambisa amanzi, njl.
- Ivalve yegesi: isetyenziselwa ukulawula ukuhamba kwegesi, njengevalve yokulawula igesi, ivalve yebhola yomoya, njl.
-Ivalve ye-oyile: isetyenziselwa ukulawula ukuhamba kweoli, njengevalve yokulawula i-hydraulic, ivalve yokutywinwa kweoli, njl.
-Ivalve yomphunga: isetyenziselwa ukulawula ukuhamba komphunga, njengevalve elawula umphunga, ivelufa yamandla omphunga, njl.
4. Yahlula ngokwenqanaba loxinzelelo:
-Ivalve yoxinzelelo oluphantsi: ilungele indawo yokusebenza yoxinzelelo oluphantsi, ngokuqhelekileyo ingaphantsi kwe-1.6MPa.
-Ivalve yoxinzelelo oluphakathi: ifanelekile kwindawo yokusebenza yoxinzelelo oluphakathi, ngokubanzi phakathi kwe-1.6MPa kunye ne-10MPa.
-Ivalve yoxinzelelo oluphezulu: ilungele indawo yokusebenza yoxinzelelo oluphezulu, ngokubanzi ingaphezulu kwe-10MPa.
Oku ngasentla kukwakheka kunye nokuhlelwa kwevalve. Xa ukhetha i-valve efanelekileyo, kuyimfuneko ukuqwalasela ngokubanzi iimfuno ezithile zobunjineli kunye neempawu zeendaba, kwaye ukhethe umenzi we-valve ophezulu ukuqinisekisa ukuthembeka kunye nobomi benkonzo yevalve. Ukufumana udliwano-ndlebe oluthe kratya kunye nesikhokelo, kuyacetyiswa ukuba uqhagamshelane nabavelisi beevalvu abaziingcali.
