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 iyasetyenziswa, ulwakhiwo lweplagi eguqulweyo kufuneka lusetyenziswe, oluya kuchaphazela ngokulula isiphumo sokutywinwa.
