Inkqubo yokusebenza ivalve ikwayinkqubo yokuhlola nokuphatha ivalve. Nangona kunjalo, le micimbi ilandelayo kufuneka ithathelwe ingqalelo xa isebenza ivalve.
I-①higy ivalve yobushushu. Xa iqondo lobushushu liphuma ngaphezulu kwe-200 ° C, iibhloko ziyatshiswa kwaye zenziwe i-ted, ekulula ukwenza itywina likhululwe. Ngeli xesha, iibhotile kufuneka "zishushu", kwaye ayifanelekanga ukwenza ishushu iqinile kwindawo evalwe ngokupheleleyo yevali, ukuphepha i-valve ekubeni ivulwe kamva.
I-②in ixesha lokuba amaqondo obushushu aphantsi kwe-0 ℃, anikele ingqalelo ekuvuleni iplani ye-valve yeevalves ezimisa amanzi afanelekileyo kunye namanzi afakiweyo, ukuze aphelise ivalve. Nika ingqalelo kwilondolozo lobushushu beevalvu ezingakwaziyo ukuphelisa ukuqokelelwa kwamanzi kunye neevali ezisebenza ngethutyana.
③ Ukupakisha i-gandm akufuneki icinezelwe ngokuqinileyo, kwaye umsebenzi oguquguqukayo we-valve stem kufuneka iphumelele (kuphosakele ukucinga ukuba i-valve ye-valve i-valte kwaye ikhule i-valque). Phantsi kwemeko yezinto ezikhuselayo, ukupakisha akunakutshintshwa okanye zongezwa phantsi koxinzelelo.

⑤ Umqhubi kufuneka abe nencwadi ekhethekileyo yelog okanye incwadi erekhodiweyo, kwaye anikele ingqalelo ekurekhoda ukusebenza kweevalva ezahlukeneyo, ngakumbi iivasta ezibalulekileyo, amaqondo obushushu aphezulu kunye neevalva eziphezulu, kubandakanya izixhobo ezizodwa. Kuya kufuneka kuqatshelwe ukusilela, unyango, iinxalenye ezitshintshiweyo, njl njl, ezi zinto zibalulekile kumqhubi ngokwawo, abasebenzi bokulungisa kunye nomenzi. Seka i-log ekhethekileyo ngoxanduva olucacileyo, oluyingenelo ukomeleza abaphathi.
Ixesha lokuphumla: Mar-15 ukuya ku-522
