Kukho iintlobo ezininzi zeevalvu, kwaye nganye ineenzuzo zayo kunye nokungalunganga.Nazi iingenelo ezintlanu eziphambili kunye nezingeloncedo, kubandakanywa iivalvu zesango, iivalvu zebhabhathane, iivalvu zebhola, iivalvu zeglowubhu kunye neevalvu zeplagi.Ndiyathemba ukukunceda.
Ivalve yeNkuku: ibhekisa kwivalve ejikelezayo evalekileyo emile okwe-plunger.Emva kokujikeleza kwe-90 °, i-port yeshaneli kwiplagi yevalve inxibelelana okanye yahlulwe kwi-channel port kumzimba wevalvu ukuphumeza ukuvula okanye ukuvala.Ubume beplagi yevalve ingaba yi-cylindrical okanye i-conical.Umgaqo ngokusisiseko ufana naleyo yevalve yebhola.Ivalve yebhola iphuhliswa ngesiseko sevalve yeplagi.Isetyenziswa ikakhulu ukugrumba indawo yeoli, kwaye ikwasetyenziswa kushishino lwepetrochemical.
inzuzo:
①Isetyenziselwa ukusebenza rhoqo, ngokukhawuleza kwaye kulula ukuvula nokuvala.
②Ukuxhathisa ulwelo kuncinci.
③ Elula, encinci, ubunzima obulula, kulula ukuyigcina.
④Ukusebenza kakuhle kokutywinwa.
⑤ Ngokuxhomekeke kumda wesalathiso sofakelo, ulwalathiso lokuhamba kwendlela ephakathi lunokuba lukhuni.
⑥Akukho ngcangcazelo kunye nengxolo ephantsi.
isiphene:
①Isigqubuthelo sikhulu kakhulu, kwaye itorque enkulu kakhulu kwaye ayibhetyebhetye ngokwaneleyo.
②Ubunzima bomzimba buchaphazeleka, kwaye umgangatho ulinganiselwe.
③Ekusetyenzisweni okwenyani, ukuba ivalve enkulu isetyenzisiwe, ulwakhiwo lweplagi eguqulweyo kufuneka lusetyenziswe, oluya kuchaphazela ngokulula isiphumo sokutywinwa.
